Hippocampal Neurogenesis

Exercise counteracts junk food's depression-like effects through gut-brain metabolic signaling

Researchers found that voluntary running exercise mitigates cafeteria diet-induced behavioral changes via hormonal and microbial pathways. The study revealed specific metabolites, such as anserine and indole-3-carboxylate, were decreased by the cafeteria diet but partially restored by exercise.

Tat-heat shock protein 10 ameliorates age-related phenotypes in the hippocampus

A new study found that HSP10 treatment improved exploratory preferences, object contacts, and swimming time in aged mice, while also increasing proliferating cells and differentiated neuroblasts. The protein also mitigated age-related gene reductions and increased sirtuin 3 levels.

Eating sea squirts may reverse the signs of ageing, study shows

A new study suggests that supplementing a diet with Ascidiacea, also known as sea squirts, reverses some main signs of aging in animal models. The researchers found that plasmalogens, vital to body processes, decrease with age and contribute to neurodegenerative diseases like Alzheimer's and Parkinson's.

Old neurons can block neurogenesis in mice

Researchers discovered that old neurons can block neurogenesis in mice, highlighting excessive senescence as a driving factor behind aging. By destroying senescent cells, the study showed enhanced hippocampal neurogenesis and cognitive function in middle-aged mice.

Rigol DP832 Triple-Output Bench Power Supply

Rigol DP832 Triple-Output Bench Power Supply powers sensors, microcontrollers, and test circuits with programmable rails and stable outputs.

“Second-hand” psychological stress can lead to depression in mice, finds study

Researchers at Tokyo University of Science discover that vicarious social defeat can cause psychological stress in mice, leading to depression and decreased neurogenesis. The study sheds light on the pathophysiology of depression and may lead to the development of novel antidepressants.
