Environmental DNA sequencing primers for eutardigrades and bdelloid rotifers

Environmental DNA sequencing primers for eutardigrades and bdelloid rotifers SUMMARY: This article talked about using soil eutardigrades and bdelloid rotifer primers to quickly and easily identify these organisms directly. Due to the fact that there are so many types of microorganisms in soil, many of which are still unidentified and unable to be cultured in… Continue reading Environmental DNA sequencing primers for eutardigrades and bdelloid rotifers

Ingestion of Lactobacillus strain regulates emotional behavior and central GABA receptor expression

Ingestion of Lactobacillus strain regulates emotional behavior and central GABA receptor expression in a mouse via the vagus nerve SUMMARY: This study looked at the effects of Lactobacillus rhamnosus on GABA receptors and the role of the vagus nerve in the gut-brain connection. Results showed that L. rhamnosus decreased cortisone levels in stressed out mice… Continue reading Ingestion of Lactobacillus strain regulates emotional behavior and central GABA receptor expression

Air Pollution, Early Life Microbiome, and Development

Air Pollution, Early Life Microbiome, and Development SUMMARY: This is a short review of how environmental factors during pregnancy could possibly affect the baby’s development after birth. Effects include being more prone to allergies, obesity, and autism. Many of the results turned out to be inconclusive. The authors give the following reasons: gut microbiota changes… Continue reading Air Pollution, Early Life Microbiome, and Development

Variation in the human immune system is largely driven by non-heritable influences

Variation in the human immune system is largely driven by non-heritable influences SUMMARY: This study was a twin study. The researchers looked at different elements of the immune system: T-cells, NK cells, B-cells, cytokines, etc. and saw that the development of these cells were influenced by non-heritable factors such as the environment and random epigenetic… Continue reading Variation in the human immune system is largely driven by non-heritable influences

Effects of Fat Loss on Inflammation

Substantial fat mass loss reduces low-grade inflammation and induces positive alteration in cardiometabolic factors in normal-weight individuals SUMMARY: This study looked at “normal weight female physique athletes” and how weight loss (specifically loss of visceral fat) decreased inflammation and increased enzymes that were beneficial for cardiovascular health. Results showed that weight loss upregulated genes that… Continue reading Effects of Fat Loss on Inflammation

How Bacteria Genes Change with Dryness

Environmental filtering of bacterial functional diversity along an aridity gradient SUMMARY: Genes of soil bacteria sampled in the Tibetan Plateau showed that as the environment got drier, the less diverse the genes were. Researchers wanted to compare bacterial gene diversity with the already-known diversity of genes in large animals in various environments. There were less… Continue reading How Bacteria Genes Change with Dryness
