SlugAtlas, a histological and 3D online resource of the land slugs Deroceras laeve and Ambigolimax valentianus.

Due to their distinctive anatomical characteristics, land slugs are appealing research subjects from a variety of angles, including stem cell biology, regeneration, embryonic development, allometry, and neurophysiology. Here we present SlugAtlas, an anatomical and histological online resource of the land slugs Deroceras laeve and Ambigolimax valentianus. The atlas is composed of series of histological sections on the horizontal, sagittal, and transversal planes for both species with 3D viewing tools of their major organs.

Analyzing the gut microbiota and microbial-associated metabolites of tomato-based sauces.

Red Cooked Sauce (RCS) and Red Raw Sauce (RRS) are a mixture of natural crops that have a promising content of bioactive compounds (BC). The aim was to determine the effect of the indigestible fraction (IF) during the colonic fermentation in RCS and RRS by studying the two-way relationship between gut microbiota composition and microbial metabolites produced from BC fermented in the TNO in vitro dynamic model of the human colon (TIM-2). Total BC in undigested and predigested RRS, 957 and 715 mg/100 g DW, respectively, was significantly higher (p < 0.

Metagenome-Assembled Genome of " Aramenus sp. CH1" from the Chichon volcano, Mexico.

The Chichon volcano contains several thermal manifestations including an acidic crater lake. Here we report a metagenome-assembled genome of " Aramenus sp. CH1," a archaeon inhabiting the crater lake from the Chichon volcano.

Cultivation of gastrointestinal microbiota in a new growth system revealed dysbiosis and metabolic disruptions in carcinoma-bearing rats.

A challenge in the study of gastrointestinal microbiota (GITm) is the validation of the genomic data with metabolic studies of the microbial communities to understand how the microbial networks work during health and sickness. To gain insights into the metabolism of the GITm, feces from healthy and sick rats with cancer were inoculated in a defined synthetic medium directed for anaerobic prokaryote growth (INC-07 medium). Significant differences between cultures of healthy and sick individuals were found: 1) the consumption of the carbon source and the enzyme activity involved in their catabolism (e.

Microbial community structure, physicochemical characteristics and predictive functionalities of the Mexican tepache fermented beverage.

Tepache is a native beverage from Mexico, which is usually elaborated with pineapple shells, brown cane sugar and is fermented naturally. Beneficial health effects have been attributed to its consumption; however, the total ecosystem of this beverage including chemicals (substrates for microbial growth, prebiotics, etc) and microbiota (probiotics), and potential functionality had not been studied. In this work, the analysis of the tepache beverage for its physicochemical characteristics, as well as its structure of microbial communities and the predictive metabolic functionalities was carried out.

Metagenomic and metabolic analyses of poly-extreme microbiome from an active crater volcano lake.

El Chichón volcano is one of the most active volcanoes in Mexico. Previous studies have described its poly-extreme conditions and its bacterial composition, although the functional features of the complete microbiome have not been characterized yet. By using metabarcoding analysis, metagenomics, metabolomics and enzymology techniques, the microbiome of the crater lake was characterized in this study.

Changes in Intestinal Microbiota and Predicted Metabolic Pathways During Colonic Fermentation of Mango ( L.)-Based Bar Indigestible Fraction.

Mango ( L.) peel and pulp are a source of dietary fiber (DF) and phenolic compounds (PCs) that constituent part of the indigestible fraction (IF). This fraction reaches the colon and acts as a carbon and energy source for intestinal microbiota.
