Sex differences in long-term outcomes among acute ischemic stroke patients with diabetes in China
Conclusions These findings suggest that it is crucial to establish the individual scheme of therapy for every patient by different risk factors of stroke, strengthen the rehabilitation of stroke, and carry on the health education early for the secondary prevention of stroke in patients with diabetes mellitus (DM).

Daily variation in time-trial sporting performance: A systematic review
Chronobiol Int. 2022 Jul 11:1-16. doi: 10.1080/07420528.2022.2090373. Online ahead of print.ABSTRACTFew functional measures related to time-trial display diurnal variation. The diversity of tests/protocols used to assess time-trial performance on diurnal effects and the lack of a standardised approach hinder agreement in the literature. Therefore, the aims of the present study were to investigate and systematically review the evidence relating to time-of-day differences in time-trial measures and to examine the main aspects related to research design important for studies of a chronobiological nature. The entire content of...

Stem Cells for Cell-Based Therapies
The world of stem cells We know the human body comprises many cell types (e.g., blood cells, skin cells, cervical cells), but we often forget to appreciate that all of these different cell types arose from a single cell—the fertilized egg. A host of sequential, awe-inspiring events occur between the fertilization of an egg and the formation of a new individual: Embryonic stem (ES) cells are also called totipotent cells. The first steps involve making more cells by simple cell division: one cell becomes two cells; two cells become four cells, etc. Each cell of early development is undifferentiated; that is, it is...

BMI Modifies the Association Between Depression Symptoms and Serum Copper Levels
Biol Trace Elem Res. 2022 Nov 27. doi: 10.1007/s12011-022-03505-y. Online ahead of print.ABSTRACTDepression is one of the most common mental disorders which dramatically threatens public health and wellness. Copper has been known to be involved in many biological processes that could help explaining the occurrence of depression. However, studies focusing on its effect have yielded mixed results. The present study aims to evaluate the association between serum copper levels and depression symptoms. It also investigates the effect of modification of BMI (body mass index) on depression symptoms. A total of 5419 US adults aged...
