Association Between the Gut #Microbiota and Blood #Pressure in a Population Cohort of 6953 Individuals
https://2medical.news/2020/08/17/association-between-the-gut-microbiota-and-blood-pressure-in-a-population-cohort-of-6953-individuals/

Several small‐scale animal studies have suggested that gut microbiota and blood pressure (BP) are linked. However, results from human studies remain scarce and conflicting. We wanted to elucidate the multivariable‐adjusted association between gut metagenome and BP in a large, representative, well‐phenotyped population sample. We performed a focused analysis to examine the previously reported inverse associations between sodium intake and Lactobacillus abundance and between Lactobacillus abundance …

Vitamin D was superior to placebo for both primary outcomes (mean differences in CAP …
CMS121, a fatty acid synthase inhibitor, protects against excess lipid peroxidation and inflammation and alleviates cognitive loss in a transgenic mouse model of #Alzheimer’s disease
https://2medical.news/2020/08/19/cms121-a-fatty-acid-synthase-inhibitor-protects-against-excess-lipid-peroxidation-and-inflammation-and-alleviates-cognitive-loss-in-a-transgenic-mouse-model-of-alzheimers-disease/

The oxidative degradation of lipids has been shown to be implicated in the progression of several neurodegenerative diseases and modulating lipid peroxidation may be efficacious for treating Alzheimer’s disease (AD). This hypothesis is strengthened by recent findings suggesting that oxytosis/ferroptosis, a cell death process characterized by increased lipid peroxidation, plays an important role in AD-related toxicities. CMS121 is a small molecule developed against these aspects …
An electrophysiological marker of #arousal level in humans
https://2medical.news/2020/08/20/an-electrophysiological-marker-of-arousal-level-in-humans/

Deep non-rapid eye movement sleep (NREM) and general anesthesia with propofol are prominent states of reduced arousal linked to the occurrence of synchronized oscillations in the electroencephalogram (EEG). Although rapid eye movement (REM) sleep is also associated with diminished arousal levels, it is characterized by a desynchronized, ‘wake-like’ EEG. This observation implies that reduced arousal states are not necessarily only defined by synchronous oscillatory activity. …

Modeling the Onset of #Symptoms of #COVID-19
https://2medical.news/2020/08/30/modeling-the-onset-of-symptoms-of-covid-19/

COVID-19 is a pandemic viral disease with catastrophic global impact. This disease is more contagious than influenza such that cluster outbreaks occur frequently. If patients with symptoms quickly underwent testing and contact tracing, these outbreaks could be contained. Unfortunately, COVID-19 patients have symptoms similar to other common illnesses. Here, we hypothesize the order of symptom occurrence could help patients and medical professionals more quickly distinguish …
