Establishment and application of a new 4/6 infarct nephrectomy rat model for moderate chronic kidney disease.

Purpose: To develop a new 4/6 infarct nephrectomy (INx) model rat mimicking moderate chronic kidney disease (CKD) and to evaluate its application.

Methods: We modified the conventional 5/6 INx rat model to create the 4/6 INx model by ligating the renal artery branch to induce infarction of one-third of the left kidney after right kidney removal and compared biochemically and histologically both models. To demonstrate the application of the 4/6 INx model, the effects of a supplementary compound containing calcium carbonate, chitosan, palm shell activated charcoal etc.

Pain and physical activity changes during the COVID-19 state of emergency among Japanese adults aged 40 years or older: A cross-sectional study.

Understanding the relationship between pain and physical activity (PA) levels is beneficial for maintaining good health status. However, the impact of pain on changes in PA during the coronavirus disease 2019 (COVID-19) pandemic is unknown. The purpose of this study was to examine whether PA levels pre-, during, and post-COVID-19 state of emergency differ between Japanese adults who had pain after the COVID-19 state of emergency and those who did not.
