Outline Activities
A purpose of my research is to elucidate a new somatic DNA recombination mechanism at developmental stages in the central nervous system.
Another research is to aim to identify genomic regions of which instability is associated with aging, including telomeric regions.
I have focused on telomeric structural changes as aging- or disease-associated genomic alterations of aged people with chronic diseases for the last 5 years.
From 2012 academic year, I conducted a　large-scale　epidemiological research with a questionnaire　of clinical history and hot spa-bathing in collaboration with the Beppu city office and the Beppu Medical Association. I have published this epidemiological study in Sciecne Reports (18; 133: 2018). I introduced this epidemiological study and therapeutic effects for severe chronic pains of fibromyalgia syndrome at 26 th international congress of applied psychology in Paris in July 2014, at 10th FENS Forum in Copenhagen in July 2016, and in the memorial lecture of 30th anniversary of sister city-ship between Rotorua and Beppu in New Zealand in June 2017.
