Rep., 10.1038/s41598-023-44161-z, 13, 16908, 2023.10, The transport and accumulation of orally administered functional food-derived peptides in the brain was not fully explored. Thus, in the present study, we aimed to provide critical evidence regarding brain accumulation of a memory-improving soy dipeptide, Tyr-Pro, following oral administration. Stable isotope-labeled Tyr-Pro (Tyr-[13C5,15N]Pro) was orally administered to male ICR mice at 10 or 100 mg/kg. Surprisingly, the intact labeled Tyr-Pro exhibited maximal plasma and brain levels 15 min after administration (plasma: area under the curve [AUC 0–120 min], 1331 ± 267 pmol·min/mL-plasma; brain: AUC 0–120 min of 0.34 ± 0.11 pmol·min/mg-dry brain, at 10 mg/kg). In addition, we detected labeled Tyr-Pro in the brain parenchyma, indicating a validated blood–brain-barrier (BBB) transportability. Moreover, we confirmed the preferable accumulation of Tyr-Pro in the hypothalamus, hippocampus, and cortex with > 0.02 pmol/mg-tissue. In conclusion, we provided the first evidence that orally administered Tyr-Pro at 10 mg/kg directly entered the blood circulation with an absorption ratio of 0.15%, of which 2.5% of Tyr-Pro was transported from the plasma to the mouse brain parenchyma..  |

HUVECs were cultured with 1 μM hesperidin for 2 h, following the measurements of nitric oxide (NO) production and vasomotor-related receptors’ expression. Hesperidin significantly promoted NO production (224.1 ± 18.3%, P was upregulated (141.2 ± 12.5%, P production. When a transient receptor potential vanilloid 1 (TRPV1) was knocked down by silencing RNA or Ca2+/calmodulindependent kinase II (CaMKII) and p38 mitogen-activated protein kinase (p38 MAPK) were inhibited, the increased MasR expression by hesperidin was abrogated. The inhibitions of CaMKII and endothelial NO synthase (eNOS) abolished the hesperidininduced NO production. The structure−activity relationship analysis of flavonoids demonstrated that the B ring of the twisted flavonoid skeleton with a hydroxy group at the 3′ position was a crucial factor for TRPV1 stimulation. Taken together, it was demonstrated that hesperidin may stimulate TRPV1-mediated cascades, leading to the activation of two signaling axes, CaMKII/p38 MAPK/MasR expression and CaMKII/eNOS/NO production in HUVECs.. |

We thus investigated the AdipoR1-agonistic potential of YP-related tripeptides in the soybean protein sequence. Among the 17 soybean candidate tripeptides, those elongated at the C-terminus of YP (0.1 μM YPG, 140 ± 16%; 0.1 μM YPE, 141 ± 22%; 0.1 μM YPP, 145 ± 19%; 0.1 μM YPQ, 143 ± 20%; p AdipoRon (163 ± 52%, p indicating that the two tripeptides had an AdipoR1 agonistic effect. CHARMM-GUI-aided molecular dynamics simulation in a virtual phospholipid membrane revealed that YPG and YPP were stably positioned at the binding pockets of AdipoR1 (binding free energy alternative adiponectin-like potential via their preferential binding to AdipoR1.. |

Nano Mater., doi.org/10.1021/acsanm.1c03890, 5, 2187-2194, 2023.02, There is no analytical system to directly and simultaneously detect taste- and odor-active compounds. Graphite carbon black (GCB) nanoparticles, a chemical adsorbent for a variety of compounds, including gaseous molecules, which consists of nanoparticles made from multilayered sheets of sp2-conjugated atomic carbon, have the characteristics required for a surface-assisted laser desorption ionization−mass spectrometry (SALDI-MS) material. Thus, in this study, GCB-LDI-MS was developed for the simultaneous detection of taste- and odor-active compounds. The proposed GCB-LDI-MS successfully detected volatile compounds, including ethyl esters, alcohols, fatty acids, and aldehydes with up to 16 carbons (maximum carbon number of the tested compounds), which could not be detected by conventional matrix-assisted-LDI-MS. Moreover, a series of taste-active compounds (e.g., amino acids and sugars) and various volatile compounds (e.g., ethyl esters, aldehydes, alcohols, fatty acids, and lactones) as a mixture in liquid samples were also detected by the present GCB-LDI-MS. Thus, the proposed simple and rapid detection technique can digitize the analysis of flavor compounds, which provides an analytical concept for flavor scanning to evaluate the palatability of food products.. |

To overcome this challenge, a fluorescence-assisted spraying method was developed for a constant matrix amount employing an MSdetectable fluorescent reagent, rhodamine 6G (R6G), which was sprayed with the matrix. To form a homogeneous matrix crystal on the tissue section, a matrix solution, 1,5-diaminonaphthalene (10 mg/mL), containing R6G (40 μg/mL) and O-dinitrobenzene (ODNB, 10 mg/mL) was sprayed until the desired constant fluorescence intensity was achieved. Compared with that obtained via conventional cycle-number-fixed spraying [relative standard deviation (RSD) = 31.1%], the reproducibility of the relative MS intensity of the analyte [ferulic acid (FA), RSD = 3.1%] to R6G was significantly improved by the fluorescence-assisted matrix spraying. This result indicated that R6G could be employed as an index of the matrix amount and an MS normalizing standard. The proposed matrix spraying successfully quantified nifedipine (0.5−40 pmol/mm2 in the positive mode, R2 = 0.965) and FA (0.5−75 pmol/mm2 in the negative mode, R2 = 0.9972) in the kidney section of a rat. Employing the quantitative MALDI-MS imaging assay, FA, which accumulated in the kidney of the rat after 50 mg/kg was orally administered, was visually determined to be 3.5, 3.0, and 0.2 μmol/g tissue at 15, 30, and 60 min, respectively.. |

Food Chem., 69, 49, 15165-15174, 2021.12, Apart from the physiological effects of glyceollins, information regarding their tissue distribution is scarce in the literature. Thus, the aim of this study is to clarify the distribution of glyceollins in rat organs. Glyceollins I and III were orally administered to Sprague-Dawley rats (1.0 mg/kg) with daidzein as control, and their accumulations in organs were investigated by liquid chromatography-time-of-flight/mass spectrometry (LC-TOF/MS). Glyceollins accumulated in intact and conjugated forms in circulatory organs with a Tmax of 0.5 h, in the following order of descending preference: liver, kidney, heart, lung, soleus muscle, and abdominal aorta. The accumulation of hydrophobic glyceollin I was more than 1.5 times higher than that of III. In contrast, daidzein and hydroxy equol were detected only in the liver and kidneys at lower concentrations (1/100 times) than those of glyceollins. In conclusion, prenylated isoflavones, glyceollins, were preferentially distributed in circulatory organs as intact, sulfated, or glucuronidated forms up to 6 h after the intake.. |

Based on the structure of the AdipoR1 agonist, AdipoRon, 15 synthetic dipeptides were targeted to promote glucose uptake in L6 myotubes. Tyr-Pro showed a significant increase in glucose uptake among the dipeptides, while other dipeptides, including Pro-Tyr, failed to exert this effect. Tyr-Pro induces glucose transporter 4 (Glut4) expression in the plasma membrane, along with adenosine monophosphate-activated protein kinase (AMPK) activation. In AdipoR1-knocked down cells, the promotion by Tyr-Pro was ameliorated, indicating that Tyr-Pro may directly interact with AdipoR1 as an agonist, followed by the activation ofAMPK/Glut4 translocation in L6 myotubes. Molecular dynamics simulations revealed that a Tyr-Pro molecule was stably positioned in the two potential binding pockets (sites 1 and 2) of the seven-transmembrane receptor, AdipoR1, anchored in a virtual 1- palmitoyl-2-oleoyl-phosphatidylcholine membrane. In conclusion, we demonstrated the antidiabetic function of the Tyr-Pro dipeptide as a possible AdipoR1 agonist.. |

Thoromb. Vasc. Biol., 41, 11, e498-e511, 2021.11, OBJECTIVE: To clarify the pathogenesis of human atheroma, the origin of deposited lipids, the developmental mechanism of liponecrotic tissue, and the significance of the oxidation of phospholipids were investigated using mass spectrometry-aided imaging and immunohistochemistry. APPROACH AND RESULTS: Atherosclerotic lesions in human coronary arteries were divided into 3 groups: pathologic intimal thickening with lipid pool, atheroma with lipid core, and atheroma with necrotic core. The lipid pool and lipid core were characterized by the deposition of extracellular lipids. The necrotic core comprised extracellular lipids and liponecrotic tissue. The proportion of cholesteryl linoleate in cholesteryl linoleate+cholesteryl oleate fraction in the extracellular lipid and liponecrotic regions differed significantly from that of the macrophage foam cell–dominant region, and the plasma-derived components (apolipoprotein B and fibrinogen) were localized in the regions. The liponecrotic region was devoid of elastic and collagen fibers and accompanied by macrophage infiltration in the surrounding tissue. Non–oxidized phospholipid (Non-OxPL), OxPL, and Mox macrophages were detected in the three lesions. In the atheroma with lipid core and atheroma with necrotic core, non-OxPL tended to localize in the superficial layer, whereas OxPL was distributed evenly. Mox macrophages were colocalized with OxPL epitopes. CONCLUSIONS: In human atherosclerosis, plasma-derived lipids accumulate to form the lipid pool of pathologic intimal thickening, lipid core of atheroma with lipid core, and necrotic core of atheroma with necrotic core. The liponecrotic tissue in the necrotic core appears to be developed by the loss of elastic and collagen fibers. Non-OxPL in the accumulated lipids is oxidized to form OxPL, which may contribute to the lesion development through Mox macrophages. |

Plasma samples taken from the tail vein up to 8 h after admin- istration were analyzed by matrix-assisted laser desorption/ionization (MALDI) and liquid chromatography- time-of-flight (LC-TOF) mass spectrometry (MS). In total, 126 signals were detected by MALDI-MS. Among the signals, nine oligopeptides (SEL, KGPL, SILGA, DSEL, GDANI, SYFV, CLQSC, GEQPRPF, and LVINEGDA) were successfully identified as β-conglycinin-derived peptides by LC-TOF/MS at a plasma concentration of 0.75–756 pmol/mL. The results demonstrated that β-conglycinin could be the dietary source protein for the oligopeptides produced prior to entering the circulating bloodstream of rats.. |

In this study, with the aid of matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) ima- ging, intestinal absorption of acylated anthocyanins was visually investigated. Anthocyanin extracts from purple carrots were orally administered to Sprague-Dawley rats. Acylated cyanidins were absorbed into portal and circulating blood systems in their intact form, and aglycon; cyanidin 3-O-(6-O-feruloyl-β-D-glucopyranosyl)- (1 → 6)-[β-D-xylopyranosyl-(1 → 2)]-β-D-galactopyranoside (Cy3XFGG), and showed a high absorption of 39.3 ± 0.1 pmol/mL-plasma at 60 min after administration. MALDI-MS imaging analysis of the rat jejunum membranes showed that an organic anion transporting polypeptide (OATP) transporter was involved in Cy3XFGG transport, while deacylated anthocyanins were incorporated through both the glucose transporter 2 and OATP routes. In conclusion, acylated anthocyanin, Cy3XFGG, can be absorbed in its intact form through intestinal OATP.. |

Funct. Foods, https://doi.org/10.1016/j.jff.2020.104273, 75, 104273, 2020.12, [URL], The study investigated the effects of theaflavins, which are intestinally non-absorbable compounds, on intestinal glucose transport in Caco-2 cells. 13C6-Glucose transport experiments clearly revealed that glucose transport across Caco-2 cells was significantly (p μM theaflavins for 24 h, the expression of SGLT1 expression was significantly (p difference in GLUT2 expression was observed. The theaflavin-induced inhibition of glucose transport was reversed by the inhibition of influx routes mediated by OATP and MCT transporters. A Wes analysis established that theaflavin-induced phosphorylation of AMPK was significantly (p endoplasmic reticulum Ca -release and CaMKK β. These findings demonstrated for the first time that theaflavins can inhibit glucose transport across Caco-2 cell monolayers through the suppression of SGLT1 expression partly via the activation of the intracellular Ca2+/CaMKK β/AMPK signaling pathway.. |

At the end of the protocol, a significant (P < 0.05) reduction in the systolic blood pressure (SBP) of approximately 60 mmHg was observed in the SHRs with the intake of hesperidin and Mikan tea. No change in the heart rate was observed between groups. Hesperidin altered the impaired vasomotor response in 28-week-old SHRs. Investigation of receptor expression related to mitogen-stimulated vasomotor action revealed that the Mas receptor (MasR) in the aorta of hesperidin-administered SHRs was up-regulated, while no changes in angiotensin II-type 1 and type 2 receptor expressions were observed. An increase in cAMP levels was confirmed in the aorta of hesperidin-administered SHRs, demonstrating that anti-hypertensive hesperidin plays a role in vessel regulation via the upregulated-MasR/cAMP axis.. |

GC analysis of extracts from the culture media of breast cancer cell lines (MCF-7, SK-BR-3, and YMB-1) using a solid-phase Porapak Q extraction revealed that two compounds of moderate volatility, 1-hexadecanol and 5-(Z)-dodecenoic acid, were detected with markedly higher amount than those in the medium of fibroblast cell line (KMST-6). Furthermore, LC-TOF/MS analysis of the extracts clarified that in addition to the above two fatty acids, the amounts of five unsaturated fatty acids [decenoic acid (C10:1), decadienoic acid (C10:2), 5-(Z)-dodecenoic acid (C12:1), 5-(Z)-tetradecenoic acid (C14:1), and tetradecadienoic acid (C14:2)] in MCF-7 medium were higher than those in medium of KMST-6. Interestingly, H2O2-oxidation of 5-(Z)-dodecenoic acid and 5-(Z)-tetradecenoic acid produced volatile aldehydes that were reported as specific volatiles in breath from various cancer patients, such as heptanal, octanal, nonanal, decanal, 2-(E)-nonenal, and 2-(E)-octenal. Thus, we concluded that these identified compounds over-produced in breast cancer cells in this study could serve as potential precursors producing reported cancer-specific volatiles.. |

| 28. | Takashi Ichinose, Hiroyasu Murasawa, Tomoko Ishijima, Shinji Okada, Keiko Abe, Saki Matsumoto, Toshiro Matsui, Shigeki Furuya, Tyr-Trp administration facilitates brain norepinephrine metabolism and ameliorates a short-term memory deficit in a mouse model of Alzheimer’s disease, PloS one, 10.1371/journal.pone.0232233, 15, 5, e0232233, 2020.05, [URL], The physiological actions of orally ingested peptides on the brain remain poorly understood. This study examined the effects of 39 orally administered synthetic Tyr-containing dipeptides on the enhancement of brain norepinephrine metabolism in mice by comparing the concentration of 3-methoxy-4-hydroxyphenylethyleneglycol (MHPG). Although Tyr-Tyr administration increased blood and cerebral cortex (Cx) Tyr concentrations the most, Tyr-Trp increased Cx MHPG concentration the most. The oral administration of Tyr-Trp ameliorated a short-term memory deficit of a mouse model of cognitive dysfunction induced by amyloid beta peptide 25–35. Gene expression profiling of mouse brain using a microarray indicated that Tyr-Trp administration led to a wide variety of changes in mRNA levels, including the upregulation of genes encoding molecules involved in catecholamine metabolism. A comparative metabolome analysis of the Cx of mice given Tyr-Trp or Tyr-Tyr demonstrated that Tyr-Trp administration yielded higher concentrations of Trp and kynurenine pathway metabolites than Tyr-Tyr administration, as well as higher L-dopa levels, which is the initial product of catecholamine metabolism. Catecholamines were not significantly increased in the Cx of the Tyr-Tyr group compared with the Tyr-Trp group, despite a marked increase in Tyr. Presumably, Tyr-Trp administration enhances catecholamine synthesis and metabolism via the upregulation of genes involved in Tyr and Trp metabolism as well as metabolites of Tyr and Trp. These findings strongly suggest that orally ingested Tyr-Trp modulates the brain metabolome involved in catecholamine metabolism and contributes to higher brain function.. |

This fermented tea contained hesperidin which has the high water-soluble property. We investigated the effects of feeding hesperidin derived from fer-mented tea leaves for 12 weeks on blood pressure in volunteers. Methods Thirty nine Subjects with high-normal blood pressure and stage I hypertension participated in a randomized, double-blind, placebo-controlled, parallel-group comparative test. Subjects consumed test beverage containing 1.20g fermented tea leaves or placebo beverAâge without tea leaves for 12 weeks. Systolic and diastolic blood pressures were measured every 4 weeks. Results Beverage containing fermented tea leaves reduced systolic blood pressures after the start of feeding. Also, systolic blood pressures were significantly lower in the test beverage group than in the placebo beverage group during feeding period. Conclusions The results suggested that feeding hesperidin derived from fermented lea leaves made by mixing thinned satsuma Mandarin fruit and tea leaves has an effect decreasing systolic blood pressures in subjects with high-nomial blood pressure and stage I hypertension.. |

To achieve complete separation, a cation-exchange/reversed-phase mixedmode copolymer resin column containing 0.81 wt% sulfo groups was used for the simultaneous LC-MS assay. The analyzed catecholamines were dopamine (DA), norepinephrine (NE), and epinephrine (E), while the metabolites lacking amino groups were 3,4-dihydroxyphenylacetic acid (DOPAC), homovanillic acid (HVA), and 3-methoxy-4- hydroxyphenylglycol (MHPG). The metabolites were separated and detected using LC-MS, on columns with and without sulfo groups. However, we could not achieve adequate separation of catecholamines on both columns using a gradient elution of 0 - 50 (v/v)% methanol containing 0.1 (v/v)% formic acid (FA). When volatile ion-pairing reagents were added to the mobile phase, they improved the retention and detection of catecholamines on the sulfonated mixed-mode column. Under optimized elution conditions, which involved a linear gradient elution of water containing 0.1 (v/v)% FA to 50 (v/v)% acetonitrile in 50 mM ammonium formate at 40°C and a 0.20 mL/min rate, all six target molecules were simultaneously detected within 25 min, when using negative mode LC-MS on a sulfonated mixed-mode column. The limits of detection (LODs) for DA, NE, E, DOPCA, HVA, and MHPG were determined to be 20.7, 12.6, 74.6, 1110, 18.7, and 3196 nM, respectively. Moreover, the established LC-MS assay allowed the detection of endogenous DA, NE, and HVA, in normal mouse brain samples at concentrations higher than 20, 9, and 4 pmol/mg, respectively.. |

Nectoux, Chizumi Abe, Shu Wei Huang, Naoto Ohno, Junji Tabata, Yuji Miyata, Kazunari Tanaka, Takashi Tanaka, Haruo Yamamura, Toshiro Matsui, Absorption and Metabolic Behavior of Hesperidin (Rutinosylated Hesperetin) after Single Oral Administration to Sprague-Dawley Rats, Journal of Agricultural and Food Chemistry, 10.1021/acs.jafc.9b03594, 67, 35, 9812-9819, 2019.09, [URL], We investigated the absorption and metabolic behavior of hesperidin (hesperetin-7-O-rutinoside) in the blood system of Sprague-Dawley rats by liquid chromatography- and matrix-assisted laser desorption ionization mass spectrometries (LC-MS and MALDI-MS). After a single oral administration of hesperidin (10 mg/kg), which was expected to be absorbed in its degraded hesperetin form, we detected intact hesperidin in the portal vein blood (tmax, 2 h) for the first time. We successfully detected glucuronized hesperidin in the circulating bloodstream, while intact hesperidin had disappeared. Further MS analyses revealed that homoeriodictyol and eriodictyol conjugates were detected in both portal and circulating blood systems. This indicated that hesperidin and/or hesperetin are susceptible to methylation and demethylation during the intestinal membrane transport process. Sulfated and glucuronized metabolites were also detected in both blood systems. In conclusion, hesperidin can enter into the circulating bloodstream in its conjugated forms, together with the conjugated forms of hesperetin, homoeriodictyol, and/or eriodictyol.. |

In the present study, MALDI-MSI was used as a visualisation technique to investigate the intestinal absorption of polyphenols. Nifedipine/phytic acid-aided MALDI-MSI was performed to visualise theaflavin-3′-O-gallate (TF3′G) and epicatechin-3-O-gallate (ECG) in the rat jejunum for 50-µM, 60-min transport experiments. Non-absorbable TF3′G was successfully visualised at the apical region, whereas absorbable ECG was detected throughout the rat jejunum. MALDI-MSI was also performed to determine the transport routes of the target metabolites. Signals corresponding to TF3′G and ECG in the membranes were diminished following treatment with inhibitors targeting the monocarboxylic acid transporter and organic anion transporting polypeptides. Enhanced visualisation of TF3′G was achieved by inhibiting efflux routes. Our findings demonstrated that the present MALDI-MSI can provide critical spatial informations on intestinal absorption of targets, by which TF3′G and ECG were incorporated into intestinal tissues, followed by efflux back to the apical compartment. In addition, MALDI-MSI analyses suggested that TF3′G was resistant to phase II metabolism during the influx/efflux processes, whereas ECG was susceptible to methylation and sulphation reactions. In conclusion, inhibitor-aided MALDI-MSI could serve as a powerful in situ visualisation technique for verifying intestinal transport routes and investigating the metabolism of penetrants.. |

The aim of this study was to identify the BBB-transportable peptides using in situ mouse perfusion experiments. Based on the structural features of Gly-N-methylated Gly (Gly-Sar), a reported BBB-transportable compound, 18 dipeptides were synthesized, and were perfused in the mouse brain for two minutes. Among the synthesized dipeptides, Gly-Sar, Gly-Pro, and Tyr-Pro were transported across the BBB with K i values of 7.60 ± 1.29, 3.49 ± 0.66, and 3.53 ± 0.74 µL/g·min, respectively, and accumulated in the mouse brain parenchyma. Additionally, using MALDI-MS/MS imaging analysis of Tyr-Pro-perfused brain, we provide evidence for Tyr-Pro accumulation in the hippocampus, hypothalamus, striatum, cerebral cortex, and cerebellum of mouse brain.. |

In accordance with administration protocols, ingestion by SDT began between the ages of 11 and 16 weeks which corresponded to normal and prediabetic stages, respectively. Daily intake of RV (4.3 mg/kg/day) led to a significant reduction in fasting blood glucose level (BGL) in 28-wk SDT (fasting BGL: control, 133.8±12.8 mg/mL; RV, 98.5±19.8 mg/mL), while no anti-diabetic effect was obtained in SDT fed from 27 weeks of age. These results demonstrated that RV has physiological potential to suppress promotion of diabetes, but not to improve the developed of onset.. |

Previously, we have shown that a cluster of non-coding RNAs, Eleanors (ESR1 locus enhancing and activating non-coding RNAs) formed RNA cloud and upregulated the ESR1 gene in the nuclei of LTED cells. Eleanors were inhibited by resveratrol through ER. Here we prepared another polyphenol, glyceollin I from stressed soybeans, and identified it as a major inhibitor of the Eleanor RNA cloud and ESR1 mRNA transcription. The inhibition was independent of ER, unlike one by resveratrol. This was consistent with a distinct tertiary structure of glyceollin I for ER binding. Glyceollin I preferentially inhibited the growth of LTED cells and induced apoptosis. Our results suggest that glyceollin I has a novel role in LTED cell inhibition through Eleanors. In other words, LTED cells or endocrine therapy-resistant breast cancer cells may be ready for apoptosis, which can be triggered with polyphenols both in ER-dependent and ER-independent manners.. |

We demonstrated that soybean protein hydrolysate (SPH) diet suppresses age-related cognitive decline via the upregulation of BDNF in a mouse model of senescence. Our purpose was to identify novel bioactive peptides in SPH, which enhance BDNF expression. We treated mouse primary astrocytes with SPH as well as with its positively charged chromatographic fraction. Significant increases in the expression of BDNF were observed in the treatment with positively charged fraction of SPH. Among the synthesized peptides, the dipeptide glycine-arginine (GR) increased BDNF expression in vitro, and LC-TOF-MS analysis showed the presence of GR in the SPH. Furthermore, its administration in vivo increased the expression of BDNF in the cerebral cortex and the number of neurons in hippocampus and cerebral cortex. These data indicate that GR might promote neurogenesis by upregulating BDNF levels.. |

The HILIC column was composed of a glycidyl methacrylate-ethylene glycol dimethacrylate copolymer attached to 8 wt% polyethyleneimine. Seven monosaccharides (reducing aldoses: D-xylose, D-allose, and D-glucose; non-reducing ketoses: D-fructose, D-psicose, D-sorbose, and D-tagatose) were targeted. In individual HPLC analysis of both aldoses and ketoses, elution with 90 v/v% acetonitrile permitted successful detection and separation only for the non-reducing ketoses. Besides, elution of a mixture of ketoses and aldoses with 85 v/v% acetonitrile containing 5 mmol/L sodium 1-octanesulfonate (OS) (pH 4.8) enabled the simultaneous separation of all seven monosaccharides within 40 min. The polyethyleneimine-attached HILIC column allowed discriminant HPLC analysis for non-reducing ketoses using elution with 90 v/v% acetonitrile, whereas elution with 85 v/v% acetonitrile containing 5 mmol/L OS simultaneously detected both ketoses and aldoses.. |

Notably, sea urchin-administered (250, 500, 1000 mg/kg) mice exhibited lower body, liver, and visceral fat weights, lower plasma levels of aspartate aminotransferase and alanine aminotransferase, and lower hepatic triacylglycerol levels than those fed carboxymethyl cellulose (CMC). Despite the high levels of cholesterol found in sea urchins, intake of these organisms had no effect on plasma cholesterol levels among the mice tested. Additionally, sea urchin consumption resulted in enhanced levels of arachidonic acid and docosahexaenoic acid within mouse livers. Lastly, mice fed HFD with sea urchin (500 mg/kg) exhibited increased mRNA expression of uncoupling protein-1 within brown adipose tissue, compared with those fed HFD with CMC. In conclusion, consumption of sea urchin might provide a protective effect against the development of obesity and/or nonalcoholic fatty liver disease.. |

Tomatoside A could not penetrate through Caco-2 cell monolayers, as observed in the transport experiments using liquid chromatography-mass spectrometry. The treatment of cells with 10 μM tomatoside A for 3 h resulted in a 46.0% reduction in glucose transport as compared to untreated cells. Western blotting analyses revealed that tomatoside A significantly (p < 0.05) suppressed the expression of glucose transporter 2 (GLUT2) in Caco-2 cells, while no change in the expression of sodium-dependent glucose transporter 1 was observed. In glucose transport experiments, the reduced glucose transport by tomatoside A was ameliorated by a protein kinase C (PKC) inhibitor and a multidrug resistance-associated protein 2 (MRP2) inhibitor. The tomatoside A-induced reduction in glucose transport was restored in cells treated with apical sodium-dependent bile acid transporter (ASBT) siRNA or an ASBT antagonist. These findings demonstrated for the first time that the nontransportable tomato seed steroidal saponin, tomatoside A, suppressed GLUT2 expression via PKC signaling pathway during the ASBT-influx/MRP2-efflux process in Caco-2 cells.. |

However, no study investigating the prevention of impaired glucose tolerance at the prediabetic stage by anti-diabetic functional foods has been reported. Thus, the present study aimed to evaluate the anti-prediabetic effect of rose hip in a prediabetic rat model. RESULTS: Spontaneously diabetic Torii (SDT) rats were supplemented with hot-water extract of rose hip at a dose of 100 mg kg–1 body weight day–1 for 12 weeks. The results obtained showed that the supplementation of rose hip extract improved impaired glucose tolerance, promoted insulin secretion, preserved pancreatic beta-cell function and suppressed plasma advanced glycation end-products formation of methylglyoxal-derived hydroimidazolone (MG-H1) residue and Nϵ-carboxymethyl-lysine residues (e.g. MG-H1, control: 465.5 ± 43.8 versus rose hip: 59.1 ± 13.0 pmol mg protein–1, P < 0.05) in SDT rats at the prediabetic stage (12–20 weeks old). CONCLUSION: The present study provides the first evidence showing that a hot-water extract of rose hip could exert an anti-prediabetic effect in a rat model.. |

Three kinds of dipeptides, glycyl-sarcosine (Gly-Sar), Trp-His, and captopril (a dipeptidomimetic drug), a Gly-Sar-Sar tripeptide, a Gly-Sar-Sar-Sar tetrapeptide, and a Gly-Sar-Sar-Sar-Sar pentapeptide were administered at doses of 10 mg/kg each to 8- and 40-week-old SHRs. The peptides were all detected in their intact forms in the blood. There was a significantly promoted absorption of di/tripeptides in aged SHRs compared with young SHRs. In contrast, the absorption of tetra/pentapeptides was not affected by aging. PepT1 expression in the mid-jejunum was significantly increased in 40-week-old SHRs compared with 8-week-old SHRs, whereas aging did not alter the expression of claudin-1, a tight junction related protein. Thus, the present results suggest that SHR aging may enhance the absorption of di/tripeptides through the enhanced PepT1 transport route, although oligopeptides may be absorbed in an age-independent manner.. |

Among five identified compounds, 5′-methylthioadenosine (MTA) exhibited comparable vasorelaxant effect (EC50 of 190 ± 40 μM) with adenosine, a known vasodilator, on 1 μM phenylephrine (PE)-contracted Sprague-Dawley rat aortic rings. MTA induced vasorelaxation in an endothelium-independent manner and independent of the adenosine receptors. MTA reduced a CaCl2-induced vasocontraction stimulated by 1 μM PE, whereas the effect was abolished in a 60 mM KCl-induced vasocontraction. This indicates that MTA was not involved in the suppression of extracellular Ca2+ influx. MTA significantly (P 2+ channel (VDCC). In conclusion, the underlying mechanism(s) of MTA-induced vasorelaxation involves the inhibition of Ca2+/CaMK II/VDCC phosphorylation pathway, resulting in the suppression of intracellular Ca2+ concentration in aortic rings.. |

This study aimed to get insights into the metabolic behaviors of some typical diabetes-related metabolites in plasma of male Spontaneously Diabetic Torii (SDT) rats during pathogenic progress of diabetes and to assess in vivo if the variation in these metabolites related to the progression of prediabetic stage. To address this question, SDT rats and Sprague Dawley (SD) rats as control were maintained from the age of 7 to 25 weeks. Five typical advanced glycation end products (AGEs) residue of plasma protein and their free adducts were determined by liquid chromatography with tandem mass detection over the duration of the investigation. The SDT rats exhibited impaired glucose tolerance since the age of 12 weeks and developed diabetes with significantly elevated fasting glucose levels after 22 weeks. At the prediabetic stage (12–21 weeks), no significant differences were observed on AGEfree adducts levels of SDT rats compared with SD rats. However, methylglyoxal- derived hydroimidazolone (MG-H1) residue contents of plasma protein were significantly elevated in SDT rats at the age of 16 weeks, whereas other AGE residues of plasma protein did not show marked difference. The present study has revealed significant increase in MG-H1 residue content of plasma protein at the prediabetic stage of a spontaneously diabetic rat model, irrespective of unaltered fasting blood glucose and constant plasma levels of other AGEs.. |

A matrix-assisted laser desorption/ionization-imaging mass spectrometry (MALDI-IMS) technique was used to visualize the distribution of tocopherol acetate in films during the migration process. A phytic acid-aided MALDIIMS using 2',4',6'-trihydroxyacetophenone as a matrix allowed us to successfully visualize the absorbed tocopherol acetate in both ethylene-vinyl acetate copolymer (EVA) and low-density polyethylene (LDPE) films after 1 weekstorage of tocopherol acetate at 40°C. The IMS technique allowed us to also visualize the actual distribution of tocopherol acetate inside the EVA/barrier/EVA laminated films, in which tocopherol acetate sorption was blocked at the barrier layer.. |

This effect was also observed in the endothelium-denuded aorta. Among the adenine analogues, N-methyladenine and benzimidazole still evoked an apparent relaxation effect, while 1-, 3- or 7-methyladenine and imidazole were no longer vasodilators. These findings demonstrate that the imino group from the uncharged imidazolium moiety in adenine played a key role in the relaxation of the contracted aorta.. |

Perylene and cellulose acetate (CA) were used as a fluorescent reagent and a polymer material, respectively. Perylene dissolved in the additives triethylene glycol diacetate (TEGDA) and glycerol triacetate (GTA) was added to the CA film. Then, the evaluation of two types of CA films, a closed-system cellulose acetate (CCA) sample and an open-system cellulose acetate (OCA) sample, was conducted. At optimized CLSM conditions (with a scanning range at a 20-lm depth from the CA film surface with 1-μm intervals and a scanning speed of 1 fps), the sorption of perylene at the inner CA film was determined. The D values of perylene in the CA film were calculated pursuant to Fick's second law. Higher D values of perylene mixed with TEGDA versus those of perylene mixed with GTA were commonly obtained for the CCA sample (TEGDA: 8.9 × 10-15 m 2/s > GTA: 1.7 × 10-15 m2/s) and the OCA sample (TEGDA: 11 × 10-15 m2/s > GTA: 3.3 × 10-15 m 2/s) because of the higher chemical affinity of TEGDA with perylene than that of GTA. Perylene indicated a higher D value and was homogeneously distributed in the case of the OCA sample; we found that diffusivity and distribution of perylene in CA film were largely affected by the multistratification treatment. We also proved that the deeper the film depth was, the lower the diffusivity of perylene was, regardless of the types of additives and films. The factors considered for the film-depth dependence of D were a gradual increase in the diffusion pathway for perylene caused by additive diffusion and the concentration dependence of the perylene D.. |

As a result of reversed-phase high-performance liquid chromatography (HPLC) separations, five prominent peaks in the acidic fraction of TBSP were obtained at 260 nm. Among the five collected peaks, we successfully identified four compounds by nuclear magnetic resonance (NMR) and mass spectrometry (MS) measurements: (+)-osbeckic acid as a dimer ([M - H]- m/z: 371.2 > 184.9 > 140.9), 5-hydroxymethyl-2-furoic acid, protocatechuic acid, and p-hydroxybenzoic acid. A vascular contractive measurement in 1.0 μM phenylephrine-contracted Sprague-Dawley rat thoracic aorta rings revealed that (+)-osbeckic acid dimer evoked a potent vasorelaxant effect with an EC50 value of 887 μM compared to other isolates (EC50: 5-hydroxymethyl-2-furoic acid, 3610 μM; protocatechuic acid, 2160 μM; p-hydroxybenzoic acid, no inhibition).

The aim of this study, therefore, was to identify α-glucosidase inhibitors in the antihyperglycaemic tea product. Results: LG tea had a threefold higher maltase-inhibitory activity (IC50 0.065 mgdried extractm L-1) than either the constituent loquat leaf or green tea alone. In addition, LG tea favourably inhibited maltase action rather than sucrase action. As a result of bioguided high-performance liquid chromatography separations of LG tea, theasinensin A, theasinensin B, strictinin and 1,6-digalloylglucose were newly identified asmaltase inhibitors with IC50 values of 142, 225, 398 and 337 μmol L-1 respectively, along with previously identified catechins and theaflavins. Conclusion: Judging from the magnitude of the α-glucosidase-inhibitory contribution of each isolated compound to the overall inhibition of LG tea, catechins were the main candidates responsible for α-glucosidase or maltase inhibition in LG tea, followed by theaflavins, theasinensins, strictinin and 1,6-digalloylglucose.. |

A 13-wk oral administration of SFS was performed daily in 8- to 21-wk-old SHRs with a dose of 200 mg/kg of body weight/d. The systolic (SBP) and diastolic (DBP) blood pressures were measured for each week during the experimental period. As a result, a significant (P 21-wk: 27 mmHg, ΔDBP21-wk: 20 mmHg). In contrast to such substantial effect by SFS intake, angiotensin I-converting enzyme activities in blood and local organs as well as pharmaceutical parameters such as serum Na+ or K+ level did not show any significant difference between in both SFS and control groups. Vasoconstriction experiment using thoracic aorta rings from 21-wk SHRs provided an interesting result that the rings from the SFS group evoked a >2-fold higher increase in the angiotensin II-stimulated constrictive response compared with the rings from the control group (P = 0.012), which suggested that the SFS-intake would be effective in possessing a higher vessel tone.Practical Application: In this study, we investigated the antihypertensive effect of newly fermented SFS in SHRs. As a result of 13-wk SFS-administration, we found a significant antihypertensive effect of the SFS. This finding strongly demonstrates that the developed SFS would be greatly beneficial for health and useful for health-related industries.. |
| 92. | Takashi Hasegawa, Toshiro Matsui, Kiyoshi Matsumoto, Application of confocal laser scanning microscope technique to visualize dynamic sorption behavior of perylene in cellulose acetate film, Journal of Applied Polymer Science, 10.1002/app.31392, 116, 3, 1552-1557, 2010.05, [URL], Additives distributed in a polymer film were visualized by a confocal laser scanning microscope (CLSM) in this study. Cellulose acetate (CA) was used as the polymer film material. Perylene as a fluorescence reagent and glycerol triacetate (GTA) as a plasticizer for CA, respectively, were selected and mixed for visualizing the absorption of perylene into CA. Under optimized CLSM conditions of an objective lens (dry, 20×) and diode laser (408 nm, 290-330 μW), a fluorescent penetrant, perylene, in GTA solution was detected in CA casting film within around 9 μm depth of the film in 60 minutes after starting the sorption study. It was also found that the fluorescence intensity of perylene became lower with the film depth. This finding suggested that CLSM could visualize the sorption behavior of perylene as a dynamic diffusion process. Analytical conditions, such as a scanning range along the Z axis (±10 or ±30 μm from an air-contact surface of the CA film) and a scan speed (1 or 30 fps) of CLSM, did not affect the fluorescence intensity of the sorbed perylene. It was concluded that a newly developed analytical methodology using CLSM was sufficient for visualizing the perylene penetrant across the cross-sectional distribution of the CA film, being capable of monitoring the sorption behavior of compounds in polymer materials without any destruction of a given absorbed film.. |

Perylene and cellulose acetate (CA) were used as a fluorescent reagent and a polymer material, respectively. Perylene dissolved in additives of glyc-erol triacetate (GTA), triethylene glycol diacetate (TEGDA), 1,3-butylene glycol diacetate (BGDA), paraffin liquid, and poly(ethylene glycol) 200 (PEG) were added onto CA film. At optimized CLSM conditions (scanning range of a 10 lm-depth from the CA film surface with 1 lm intervals and a scanning speed of 1 fps), the sorption of perylene at the inner CA film was determined. Diffusion coefficients of perylene in the CA film were calculated according to Fick's second law. When perylene was dissolved in TEGDA, the highest diffusion coefficient, 8.9 × 10-15 m 2/s, among the additives was obtained because of high affinity of TEGDA with perylene, whereas the lowest diffusion coefficient was observed in paraffin liquid, which showed a low affinity with perylene. The diffusion coefficients of perylene in GTA, BGDA, and PEG also revealed that physical parameters, such as molecular size and viscosity, of the additives were additional factors affecting the perylene diffusivity in the CA film.. |

The three acylated sophoroses were determined as 6-O-(E)-caffeoyl-(2-O-(6-O-acyl)-β-D-glucopyranosyl)-D-glucopyranoses, where acyl was (E)-caffeoyl, p-hydroxybenzoyl, and (E)-feruloyl, respectively. The four acylated anthocyanins were also determined as cyanidin 3-O-(6-O-(E)-caffeoyl-(2-O-(6-O-(E)-feruloyl)β-D-glucopyranosyl) -β-D-glucopyranoside), in addition to peonidin 3-O-(6-O-(E)-caffeoyl-(2-O- (6-O-acyl)D-glucopyranosyl)-β-D-glucopyranosides), where acyl was (E)-caffeoyl, p-hydroxybenzoyl, and (£)-feruloyl, respectively. The diacylated sophoroses showed higher antioxidant capacity than that of monoacylated analogue 6-caffeoylsophorose, so the multiacylation established to enhance their antioxidant capacity. Similarly, 5-deglucosylated anthocyanins also gave somewhat stronger antioxidation than corresponding sweet potato anthocyanins. In rat intestinal α-glucosidase inhibition study, the diacylated sophoroses preferably inhibited maltase rather than sucrase with an IC50 value of <300 μM, indicating a potential role as antidiabetic phytochemicals. These acylated polyphenols in a red vinegar were expected to play important functional roles for health.. |

Synthetic 15 Trp-His (WH) skeleton analogues were used for rat aorta ring's force measurements, since WH was found to be a vasoactive di-peptide so far. Among the synthesized peptides consisted of both His and Trp amino acid residues, His-Arg-Trp (HRW) was found to evoke the most potent vasodilation with an EC50 value of 1.2 ± 0.08 mM in an endothelium-independent manner, while no effect was evoked by a mixture of individual amino acids. In addition to the structure of tri-peptides-activity relationship, chemically modified HRW analogues, i.e., 1- or 3-methyl-His-Arg-Trp and His-citrulline-Trp demonstrated the structural importance of tri-peptide to evoke the vasoactivity as following factors: (1) Neutral imidazole and indole groups from His and Trp residues at N- and C-terminals, respectively and (2) basic amino acids at the middle position. In mitogen (10 μM angiotensin II or 50 μM Bay K8644)-stimulated vascular smooth muscle cells, vasoactive HRW (100 μM) caused significant [Ca2+]i reduction to an extent of >30%. Thus, our results suggest that HRW caused vasodilation action via an endothelium-independent mechanism which probably involves the suppression of extracellular Ca2+ influx through voltage-gated l-type Ca2+ channel.. |

The fermented tea obtained by tea-rolling processing of tea and loquat leaves had a strong, distinctive flavor and a plain aftertaste, which differed from usual black, green, and oolong teas. The phenolic constituents were similar to those of black tea. However, the concentrations of theaflavin 3-O-gallate, theaflavin 3,3′-di-O-gallate, and thearubigins were higher in the tea leaves kneaded with loquat leaves than in tea leaves kneaded without loquat leaves. The results from in vitro experiments suggested that acceleration of catechin oxidation was caused by the strong oxidation activity of loquat leaf enzymes and a coupled oxidation mechanism with caffeoyl quinic acids, which are the major phenolic constituents of loquat leaves.. |

Through an Ussing transport investigation of SFS across caco-2 cell monolayers, three di-peptides, Ala-Phe, Phe-Ile and Ile-Phe, were successfully identified from the SFS as transportable inhibitory peptides. Ala-Phe and Ile-Phe, but not Phe-Ile, exhibited ACE-inhibitory activity with IC50 values of 165.3 μM and 65.8 μM, respectively. Kinetic studies revealed that Ile-Phe (Km: 3.1 mM, Papp: 2.4 × 10-6 cm/s) exhibited greater affinity toward the transport compared with Ala-Phe (Km: 48.1 mM, Papp: 1.4 × 10-6 cm/s) and Phe-Ile (Km: 12.7 mM, Papp: 1.4 × 10-6 cm/s).. |

It was initially demonstrated that theaflavins and catechins preferentially inhibited maltase rather than sucrase in an immobilized AGH inhibitory assay system. For the maltase inhibitory effects of theaflavins, the effects were observed in descending order of potency of theaflavin (TF)-3-O-gallate (Gal) > TF-3,3′-di-O-Gal > TF-3′-O-Gal > TF. This suggests that the AGH inhibition induced by theaflavins is closely associated with the presence of a free hydroxyl group at the 3′-position of TF as well as the esterification of TF with a mono-Gal group. In addition, the R-configuration at the 3′-position of TF-3-O-Gal showed a higher inhibitory activity than the S-configuration. As a result of a single oral administration of maltose (2 g/kg) in rats, a significant reduction in blood glucose level was observed at a dose of 10 mg/kg of TF-3-O-Gal, demonstrating for the first time that TF-3-O-Gal can suppress glucose production from maltose through inhibition of AGH in the gut.. |

Immobilized AGH (iAGH) inhibition study by synthetic inhibitors (acarbose and voglibose) revealed that the magnitude of inhibition differed from that in the free AGH (fAGH) study: IC50 value of acarbose in iAGH-maltase assay system, 340 - 430 nM; fAGH, 11 nM. iAGH-maltase inhibition by both inhibitors was influenced by blocking reagents with different functional groups (COOH, OH, CH3, and NH2 groups). On the other hand, significant iAGH-sucrase inhibitory activity was observed only when using the negatively charged support induced by 0.1 M β-alanine. The K(m) values obtained in the iAGH assay system were similar to those from the fAGH method. With natural inhibitors, the iAGH-sucrase inhibitory activity of D-xylose, with in vivo glucose suppression, increased twice compared to that in fAGH. Green tea extract gave almost the same inhibition for both AGH assay systems.. |

The toxicity test of AG50W fraction purified from the WG hydrolysate and IVY in tidy mice revealed that 1 week median lethal concentrations of AG fraction and IVY were less than 100 and 10 mg/kg, respectively. As a result of an intravenous administration test of both inhibitors in spontaneously hypertensive rat (SHR), the mean arterial blood pressure (MAP) significantly decreased with the dose; the MAP reduction of 10.3 and 19.2 mmHg was observed at a dose of 50 mg/kg of AG fraction and 5 mg/kg of IVY, respectively. In addition to this behavior, the MAP gradually decreased after the 5 mg/kg of IVY injection (time to give a maximum reduction; 8 min), and the reduction was held for 20 min. By using rat and human plasma, IVY was found to be metabolized by the action of aminopeptidase in plasma to form a subsequent ACE inhibitor, Val- Tyr (VY). Thus, the intake of IVY as a physiologically functional food would serve in the lowering of blood pressure (BP) by the combined depressor effect of itself and its metabolite after the absorption.. |

There were no differences in supine plasma levels of Ang I, Ang II, and Ang (5-8) between the NT and HT groups: Ang I, 304 ± 43 fmol/ml vs. 293 ± 15 fmol/ml; Ang II, 32 ± 6 fmol/ml vs. 43 ± 10 fmol/ml; Ang (5-8), 176 ± 22 fmol/ml vs. 133 ± 32 fmol/ml. In addition, there were no significant differences between groups in any of these Ang levels when measured after standing for 60 min. However, the HT group showed significantly reduced supine and upright plasma Ang (3-8) and Ang (3-4) levels as compared to the NT group. In particular, the supine plasma level of Ang (3-4) (71 ± 13 fmol/ml-plasma) in the HT group was significantly (1/3-fold) lower than that in the NT group (197 ± 35 fmol/ml-plasma). An inverse correlation between the plasma level of Ang (3-4) and the upright systolic blood pressure (r = -0.627, p < 0.02, n = 13) was observed, indicating that the metabolism of Ang (3-4) might have been associated with the change in blood pressure.. |

The sorptions of ethyl hexanoate, octanal, and octanol into LDPE film were ∼1.7, 16.5, and 2.5 times higher than those in the 0% (v/v) ethanol solution, respectively (for EVOH film, the sorption increments of these compounds were ∼6.2, 3.5, and 4.1 times, respectively). To better understand this phenomenon, the solvent properties of ethanol solutions were investigated. The dielectric constants were roughly unchanged in the range 5-15% (v/v) ethanol. According to the results obtained by 1H NMR measurement, in which the difference in proton chemical shift from water-d (HDO) and ethyl alcohol-d (EtOD) became maximum at 23% (v/v) ethanol solution, the structural change of water induced by the addition of ethanol would be great up to 23% (v/v) ethanol. These results accurately reflected the sorption behavior. Therefore, the specific sorption behavior of flavor compounds from an ethanol solution would be brought about by the heterogeneous water-ethanol structure.. |

Human plasma (10 ml) ultrafiltered with a Molucut L (< M.W. 5000) was put directly on a reversed-phase column for HPLC with an UV detector. The fractions containing each angiotensin were derivatized with 0.1 mM NDA in the presence of cyanide for 60 min at ambient temperature. The derivatized angiotensin (NDA-ANG) was injected onto the HPLC system with a fluorometric detector. Excitation and emission wavelengths were set at 420 nm and 490 nm, respectively. The peak areas of NDA-ANG were linearly related with the amount of angiotensin applied, and were highly reproducible (3.5%, n=5). The concentrations of ANG I, II and III in plasma, calculated from the respective calibration curve, were 315.8 pg/ml, 19.2pg/ml and <1.3pg/ml, respectively. The concentration of ANG II obtained by this fluorometric method coincided with that (22.6 pg/ml) by radioimmunoassay.. |

Eleven new ACE inhibitory peptides, constructed with 2 to 4 amino acid residues, were isolated from the hydrolyzate. The ACE inhibitory activity of each was mostly below 100 μM of IC50 value; the maximal inhibitory activity was observed for Lys-Trp (IC50 = 1.63 μM). The isolated peptides inhibited ACE competitively, except for Met-Tyr with non-competitive inhibition. As the result of sequence homology, Arg-Val-Tyr isolated from the hydrolyzate was found in the primary structure of angiotensins I, II, and III, and of des Asp[1]-angiotensin I.. |

Considering the practical application of preparations as a functional food material, the best proteolytic conditions with respect to taste, solubility and ACE inhibitory activity were a 0.3 wt% addition of the enzyme and 17-h proteolysis at 50°C and pH 9.0. The preparations under these conditions had potent activity (IC50=0.26 mg protein/ml). Fractionation of the preparations on an ODS column with ethanol resulted in the production of more potent inhibitors. The most potent activity was obtained when eluting with 10% ethanol (IC50=0.015 mg protein/ml). This fraction was apparently rich in acidic amino acids, poor in hydrophobic ones, and effective for use as a physiologically functional food material by virtue of little bitterness, a fish odor and powerful ACE inhibitory activity.. |

Knowledge of their bioavailabilities and metabolism is important for understanding the mechanisms underlying their benefits. Thus, mass spectrometry (MS)-based analytical techniques, such as liquid chromatography-MS (LC-MS), that are capable of highly sensitive and simultaneous detection of absorbed polyphenols and their metabolites are essential tools in this field. Matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) imaging is currently used in biological sciences for visualizing the spatial information of various compounds, such as peptides, proteins, lipids, drugs, and food compounds, in various biological tissues. However, the application of MALDI-MS imaging to polyphenols is challenging owing to the lack of appropriate matrix reagents for visualizing (or detecting) polyphenols absorbed in target biological tissues. This review highlights the development of the MALDI-MS imaging technique for the detection and visualization of food-derived polyphenols. First, the development of new matrices and matrix additives for the detection and visualization of polyphenols is discussed, followed by their introduction to inhibitor-aided MALDI-MS imaging for the elucidation of intestinal absorption routes and the metabolic behaviors of polyphenols. The MALDI-MS imaging technique shows great potential as a novel analytical tool for elucidating the bioavailabilities of food-derived polyphenols.. |
| 12. | Weilin Shen, Toshiro Matsui, Intestinal absorption of small peptides a review, International Journal of Food Science and Technology, 10.1111/ijfs.14048, 2019.06, [URL], Peptides display diverse structural features because of their varied amino acid compositions. The structural diversity often imparts them complex physiological functions, or possible health-beneficial effects. Some small peptides (di-/tripeptides) exert preventive effects against conditions such as hypertension, hypercholesterolaemia and atherosclerosis. Despite their health benefits, a limited understanding of peptide absorption may hinder their extensive application. Therefore, this review briefly introduces the in vitro and in vivo findings on the intestinal absorption of small peptides and potential factors affecting their absorption.. |

Development of a new cancer detection method is expected to become a breakthrough to solve various problems for early detection. It has been reported that there is the specific odors of cancer by using bio olfaction such as dogs, and it has been recognized that there is the odors of cancer. Cancer cells acquire malignant traits as a result of metabolic changes originating from genetic mutation. The cancer specific odorous substances may be considered to be the end products of their metabolic changes. Omics researches such as genomics, proteomics, and metabolomics have been extensively performed to comprehensively analyze changes in DNA, RNA, protein, metabolism and its products specific to cancer for the purpose of developing a new cancer detection marker. It is thought that the research on the odor of cancer is also on the line of omics research. It is difficult to identify cancer-specific odorants buried in various environmental substances. However, it is expected that human will be able to acquire the technology, from the fact that they can be recognized by biological olfaction. We are continuing the research with the dream that identification of the odorous substances as a new cancer detection marker and sensor development for it will lead to the happiness of colleagues in the world.. |
