Effect of L. on Improving Insulin Secretory Capacity and Resistance in Elderly Patients Aged 80 Years Old or Older Who Develop Diabetes After COVID-19 Infection.

(1) Background: It has been reported that people affected by COVID-19, an infectious disease caused by SARS-CoV-2, suffer from various diseases, after infection. One of the most serious problems is the increased risk of developing diabetes after COVID-19 infection. However, a treatment for post-COVID-19 infection diabetes has not yet been established.

Granulomatous inflammatory responses are elicited in the liver of PD-1 knockout mice by genome mutagenesis.

Introduction: Programmed death-1 (PD-1) is a negative regulator of immune responses. Upon deletion of PD-1 in mice, symptoms of autoimmunity developed only after they got old. In a model experiment in cancer immunotherapy, PD-1 was shown to prevent cytotoxic T lymphocytes from attacking cancer cells that expressed neoantigens derived from genome mutations.

[Migration of Metals Contained in Laminated Films for Food Packaging].

Multilayer laminated films are widely used as food packaging materials. The substances contained in these films have the potential to migrate into food in contact, but the actual situation is unknown. In this study, we first determined the contents of 24 elements in 42 food laminate bags by ICP-OES and ICP-MS.

Japan's Conditional/Time-Limited Early Approval System in Regenerative Medicine: A Case Study of Rise and Falls of Autologous Skeletal Myoblast Sheets.

Japan's conditional/time-limited early approval program, initiated in 2014, aimed to advance regenerative medicine by expediting market access. However, the withdrawal of autologous skeletal myoblast sheets (Heartsheet) due to ineffectiveness raises concerns about the balance between rapid approval and scientific integrity. While the program seeks to boost innovation, it risks endorsing costly, unclear treatments under national health care.
