Antibiotic resistant characteristics from 16S rRNA [PDF]

arXiv, 2012
Background: Microbiota have evolved to acclimate themselves to many environments. Humanity is become ever increasingly medicated and many of those medications are antibiotics. Sadly, Microbiota are adapting to medication and with each passing generation they become more difficult to subdue.

Gut Microbiota Colonization in Early Life Influences Susceptibility to Adulthood Hepatic Lipid Accumulation in High‐Fat‐Diet‐Fed Mice

Advanced Science, EarlyView.
This study indicates that perinatal antibiotic exposure elevates susceptibility to high‐fat‐diet‐induced hepatic lipid accumulation via disrupting early‐life gut microbiota colonization. The decreased Lactobacillus colonization inhibits primary‐to‐secondary bile acid conversion, lowering secondary bile acids, enhancing adulthood intestinal lipid ...

Prediction analysis for microbiome sequencing data [PDF]

arXiv, 2017
One primary goal of human microbiome studies is to predict host traits based on human microbiota. However, microbial community sequencing data present significant challenges to the development of statistical methods. In particular, the samples have different library sizes, the data contain many zeros and are often over-dispersed.

Nutrition and microbiota

Nutrición Hospitalaria, 2023
The microbes that reside in our human body make up our microbiota, and their genes are known as the microbiome. The gut microbiota is involved in a wide variety of functions. At present there is considerable evidence indicating that in the last 60 years there has been an important change in the composition of our microbiota.

The Semi‐Natural Climate Chambers across Latitudes: A Broadly Applicable Husbandry and Experimental System for Terrestrial Ectotherms under Climate Change

Advanced Science, EarlyView.
Assessing species' vulnerabilities across geographical gradients is essential for biodiversity conservation under climate change. To address this challenge, the semi‐natural climate chamber across latitudes (SCCAL) is developed, a validated system capable of simulating thermal environments for ecological experiments without reliance on water or ...

Simple fabrication of an electrospun polystyrene microfiber filter that meets N95 filtering facepiece respirator filtration and breathability standards

Journal of Applied Polymer Science, Volume 140, Issue 5, February 5, 2023., 2023
The COVID‐19 pandemic led to a backlog of filtration material for N95 Filtering Facepiece Respirators (FFRs). An alternative face mask filter material is presented, consisting of an unsupported, nonwoven layer of uncharged polystyrene microfibers. This microfiber material meets NIOSH N95 FFR filtration and breathability requirements, demonstrates ...

Food Additives And Microbiota

Northern Clinics of Istanbul, 2019
The use of food additives in food production is inevitable in this modern world. Although only a safe amount of food additives is approved, their safety has always been questioned. To our knowledge, the effects of food additives on microbiota have not been investigated in a detailed manner in the literature so far.

A Model of Epigenetic Inheritance Accounts for Unexpected Adaptation to Unforeseen Challenges

Advanced Science, EarlyView.
A general model of inheriting changes that are acquired during the lifetime of individuals demonstrates tremendous benefits to the population, including escape from extinction in changing environments. Contrasting the model with experimental data shows that inheritance of acquired changes enables rapid adaptation to unforeseen challenges, and accounts ...

Multi‐omics analyses reveal the interaction between colonic microbiota and host in Min and Yorkshire pigs

Animal Research and One Health, EarlyView., 2023
In the present study, we created the weight gain models with Min and Yorkshire pigs and conducted the metagenomics and metabolomics of colon contents and transcriptomics of colon tissue. Further, we revealed the characteristics and functions of the colonic microbiota in Min and Yorkshire pigs and analyzed their interactions with the host. Overall, this

Habitat Fluctuations Drive Species Covariation in the Human Microbiota [PDF]

arXiv, 2015
Two species with similar resource requirements respond in a characteristic way to variations in their habitat -- their abundances rise and fall in concert. We use this idea to learn how bacterial populations in the microbiota respond to habitat conditions that vary from person-to-person across the human population. Our mathematical framework shows that
