Scientists publish recipe for making blood vessel cells from patient stem cells

by NIH, National Eye Institute (NEI) Graphical abstract. Credit: STAR Protocols (2023). DOI: 10.1016/j.xpro.2023.102292 Researchers at NIH’s National Eye Institute have published a detailed protocol for making three cell types that are key components to form blood vessels and capillaries. The technique enables researchers to make tissues for study and potentially for future treatments. “This protocol generates vascular endothelial cells, pericytes,...

Ear acupuncture with beads may help with shedding pounds

by European Association for the Study of Obesity Credit: CC0 Public Domain Ear acupuncture using metal beads can help reduce weight, body mass index (BMI), and body fat in combination with a restricted diet, according to new research being presented at this year’s European Congress on Obesity (ECO) in Dublin, Ireland (May 17-20). The study by Dr. Takahiro Fujimoto...

Scientists identify mutated gene behind mirror movement disorder

by the University of Montreal Arhgef7 is required for Netrin-1–mediated commissural axon guidance. (A) The mean mRNA expression, fragments per kilobase of transcript per million mapped reads (fpkm), (± SEM) of Arhgef7 and Dcc in dissociated commissural neurons (n = 3). (B) Dissociated commissural neurons were fixed and immunostained for Arhgef7 and Dcc. Scale bar,...

Magnetic stimulation treats depression by fixing “backwards” brain signals

By Michael Irving May 17, 2023 Stanford scientists have uncovered a new mechanism behind depression – and shown how magnetic stimulation can help treat it. Depositphotos Stanford scientists have discovered a major biological mechanism behind severe depression, and shown how to treat it. Signals between two key parts of the brain seem to flow the...

Dietary recommendations for cardiovascular health challenged by new evidence on saturated fatty acids’ effects on LDL-C and Lp(a) levels

A recent perspective piece published in The American Journal of Clinical Nutrition discussed current dietary recommendations to reduce the intake of saturated fatty acids and modulate the risk of cardiovascular disease while highlighting the impact of lower saturated fatty acid intake on low-density lipoprotein cholesterol (LDL-C) and lipoprotein A. Study: Lipoprotein(a) and Diet – A Challenge...
