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

The evolution of diatoms and their biogeochemical functions

The evolution of diatoms and their biogeochemical functions SUMMARY: This article talks about the evolution, cell structure, and ecological role of diatoms. The first section is an introduction to what diatoms are. The second section talks about the evolution of photosynthesis (from cyanobacteria to eukaryotes with chloroplast). The third section explains the significance of the… Continue reading The evolution of diatoms and their biogeochemical functions

Serotonin as a link between the gut-brain-microbiome axis in autism spectrum disorders

Serotonin as a link between the gut-brain-microbiome axis in autism spectrum disorders SUMMARY: This paper reviews the studies looking at the connection between serotonin production, microbiome, and autism. The first two sections give some basic information on serotonin, its reuptake transporter, and the gut-brain connection. Sections three and four talk about changes in serotonin (either… Continue reading Serotonin as a link between the gut-brain-microbiome axis in autism spectrum disorders

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
