MODULATION OF GUT MICROBIOTA THROUGH PHYSICAL ACTIVITY IN INDIVIDUALS WITH OBESITY - A SYSTEMATIC REVIEW.

Overweight/obesity (OW/OB) have been associated with gut dysbiosis, changes in gastrointestinal motility and sedentary behavior, contributing to metabolic and inflammatory alterations. This systematic review aims to assess the evidence supporting the influence of physical activity and exercise on gut microbiota composition and diversity in OW/OB and was conducted according to PRISMA guidelines, using Medline, Embase, Ebsco and Scopus databases. Risk of bias was assessed with RoB 2 for randomized controlled trials (RCT), ROBINS-I for non-RCT and JBI Critical Appraisal tool for cross-sectional studies.

Optimization of lung tissue pre-treatment by bead homogenization for subsequent culturomics.

The discovery that the lung harbors a diverse microbiome, as revealed by next-generation sequencing, has significantly altered our understanding of respiratory health and disease. Despite the association between the lung microbiota and disease, the nature of their relationship remains poorly understood, and culture isolation of these microorganisms could help to determine their role in lung physiology. Current procedures for processing samples from the lower respiratory tract have been shown to affect the viability of microorganisms, so it is crucial to develop new methods to improve their survival.

Nanoemulsions Based on Soluble Chenopodin/Alginate Complex for Colonic Delivery of Quercetin.

Inflammatory bowel disease (IBD) is an autoimmune disorder caused by uncontrolled immune activation and the subsequent destruction of the colon tissue. Quercetin (Qt) is a natural antioxidant and anti-inflammatory agent proposed as an alternative to mitigate IBD. However, its use is limited by its low oral bioavailability.

Acute Administration of Calafate (Berberis microphylla) Extract Induces the Expression of Thermogenic Markers and Modulates Gut Microbiota in Mice Fed a High-Fat Chow Diet.

Introduction: Obesity, characterized by excess adipose tissue, is a major public health problem worldwide. Brown adipose tissue (BAT) and beige adipose tissue participate in thermogenesis through uncoupling protein 1 (UCP1). Polyphenols including those from Calafate (a native polyphenol-rich Patagonian berry), are considered as potential anti-obesity compounds due to their pro-thermogenic characteristics.

Sucralose and stevia consumption leads to intergenerational alterations in body weight and intestinal expression of histone deacetylase 3.

Objectives: It is unclear whether parental consumption of non-nutritive sweetener (NNS) can affect subsequent generations. The aim of this study was to determine whether chronic parental consumption of sucralose and stevia in mice affects body weight gain and liver and intestinal expression of histone deacetylase 3 (Hdac3) in these animals and in the subsequent first filial (F1) and second filial (F2) generations.

Methods: Male and female mice (n = 47) were divided into three groups to receive water alone or supplemented with sucralose (0.
