Journal of Diabetes, Volume 15, Issue 1, Page 7-14, January 2023., 2023 Highlights Red blood cell (RBC) lifespan variation, is the main cause of variation in glycosylated hemoglobin (HbA1c), independent of blood glucose levels. This study highlighted the important impact of RBC lifespan on HbA1c test value in T2DM with HbA1c test value <7%. We discovered that the HbA1c test value in type 2 diabetes (T2DM) patients with RBC

Combined effects of life‐history traits and human impact on extinction risk of freshwater megafauna
Conservation Biology, Volume 35, Issue 2, Page 643-653, April 2021., 2021 Abstract Megafauna species are intrinsically vulnerable to human impact. Freshwater megafauna (i.e., freshwater animals ≥30 kg, including fishes, mammals, reptiles, and amphibians) are subject to intensive and increasing threats. Thirty‐four species are listed as critically endangered on the International Union for Conservation of Nature (IUCN).
