An international research group conducting final-phase clinical trials on a new treatment drug for Alzheimer's disease says it has confirmed the drug's efficacy in slowing the progression of the illness.
The Japanese pharmaceutical company Eisai has been testing the drug lecanemab together with the University of Tokyo, Yale University's School of Medicine and others.
Foreign researchers have called on the Japanese government to ease its entry restrictions to allow foreign students to re-enter the country.
The researchers who have been studying in Japan for many years made the appeal at an online news conference on Wednesday. They took part from the prefectures of Hiroshima and Fukuoka, and elsewhere.
A group of researchers at the University of Tokyo says symptoms of 10 out of 11 COVID-19 patients were alleviated after taking a pancreatitis drug Futhan together with an anti-flu drug Avigan.
The team used a combination of Futhan and Avigan on the 11 patients suffering serious pneumonia in April. Futhan is normally used for acute pancreatitis, as well as other diseases that cause blood clots in various parts of the body.
Researchers in Japan are working on a new way to estimate the death toll from the coronavirus in the country, using a method called "excess mortality."
The method estimates the death tally from an epidemic by comparing the expected number of fatalities if there had been no outbreak with the death toll that was actually recorded.
Teams of researchers from across the world have reported on how some patients infected with the new coronavirus have recovered.
A group at the US Centers for Disease Control and Prevention published a report in a medical magazine on the treatment of a 35-year-old male patient who returned from Chinese city of Wuhan, the epicenter of outbreak. He was confirmed to have been infected after complaining of coughing and a fever.
A group of researchers says global warming could slow down the speed of typhoons passing over or near Japan, leading to greater damage.
The group is led by Munehiko Yamaguchi, a senior researcher at the Japan Meteorological Agency's Meteorological Research Institute.
