The Ryukyu long-furred rat, (Rodentia: Muridae), is an endangered species endemic to the Tokunoshima, Amami-Oshima, and Okinawajima Islands, which are part of Japan's southwestern islands. During the pathological examination of a deceased wild individual from Tokunoshima Island, lymphoma and infection with three nonnative parasites, (Nematoda: Angiostrongylidae) (Nematoda: Trichosomoididae) and (Cestoda: Taeniidae), were identified. Among these, is a zoonotic species, with invasive rats as the final hosts and mollusks as intermediate hosts. Although the presence of has been widely reported across the southwestern islands of Japan, this is the first record of this species on the Tokunoshima Island. With this study, infection in wild is now confirmed in populations from all three islands where this species is found.

Background: Japan is a country often subject to natural disasters, influenced by a rapidly increasing aging demographic. The current research aims to analyze the food distribution for elderly evacuees who were relocated to a care facility in Wajima City, administered by the non-profit organization Tokushukai Medical Assistant Team (TMAT), post the Noto Peninsula Earthquake on 1 January 2024. A significant portion of the shelter's inhabitants were elderly individuals.

Article Synopsis
  • Habu snakes, a type of pit viper found in southwestern Japan, show physiological differences between populations on the islands of Tokunoshima and Amami-Oshima due to varying environmental factors.
  • Research focused on the aortas of these snakes revealed that Tokunoshima Habu exhibited stronger contractile responses to certain substances like angiotensin II and acetylcholine compared to those from Amami-Oshima.
  • The study found that acetylcholine caused contractions in the aortas of both populations, a discovery that had not been previously reported in snakes, suggesting significant differences in how these snakes react to vasoconstrictors.

Article Synopsis
  • * Three neuroemergency cases during the pandemic highlighted the effectiveness of telehealth, as it facilitated two out of three patients' transport to tertiary hospitals, saving significant costs.
  • * The findings suggest that tele-healthcare not only offers economic benefits during emergencies but also emphasizes the need for reliable systems that can operate during power outages, advocating for sustainable solutions like solar energy in preparation for disasters.
