Variations in the gut of craniid (inarticulated) brachiopods.

Zoolog Sci

Department of Geology, University of Otago, Box 56, Dunedin 9054, New Zealand.

Published: August 2014

Specimens of six species (from two genera) of inarticulated craniid brachiopod were dissected and the gut examined and compared. The gut of the five Novocrania Lee & Brunton 2001 species were very similar, except for some variations in the configuration of the pylorus-intestine. The gut of Neoancistrocrania Laurin 1992 had two distinctly different features from Novocrania; the pharynx-esophagus-stomach forms a dorsally directed half loop and the pylorus-intestine is straight. Neoancistrocrania has four unique soft-tissue features and should remain a separate genus from Novocrania.

Background: The human gut microbiota develops in concordance with its host over a lifetime, resulting in age-related shifts in community structure and metabolic function. Little is known about whether these changes impact the community's response to microbiome-targeted therapeutics. Providing critical information on this subject, faecal microbiomes of subjects from six age groups, spanning from infancy to 70-year-old adults (n = six per age group) were harvested.

Human milk oligosaccharides (HMOs), the third most abundant solid component in human milk, vary significantly among women due to factors such as secretor status, race, geography, season, maternal nutrition and weight, gestational age, and delivery method. In recent studies, HMOs have been shown to have a variety of functional roles in the development of infants. Because HMOs are not digested by infants, they act as metabolic substrates for certain bacteria, helping to establish the infant's gut microbiota.

Research Network on Chronicity, Primary Care and Health Promotion (RICAPPS), 37005 Salamanca, Spain.

Background: Recent research highlights the potential role of sex-specific variations in cardiovascular disease. The gut microbiome has been shown to differ between the sexes in patients with cardiovascular risk factors.

Objectives: The main objective of this study is to analyze the differences between women and men in the relationship between gut microbiota and measures of arterial stiffness.

Sex-Based Differences in the In Vitro Digestibility of MCT Emulsions Stabilized by Various Emulsifiers.

Consumer sex influences phenotypic differences in digestive functions that may underlie variations in food disintegration. This study used an in vitro digestion model to test the hypothesis that emulsions follow distinct digestive pathways in men and women. Model emulsions were prepared using medium-chain triglycerides stabilized by beta-lactoglobulin, alpha-lactalbumin, or lactoferrin, and by three non-protein emulsifiers: Tween 80, lecithin, and sucrose esters.

Variations in extracellular vesicle shedding of Cystoisospora suis stages (Apicomplexa: Coccidia).

Int J Parasitol

Institute of Parasitology, Department for Biological Sciences and Pathobiology, University of Veterinary Medicine Vienna, Veterinärplatz 1 A-1210 Vienna, Austria.

Cystoisospora suis, a porcine enteral parasite of the order Coccidia, is characterized by a complex life cycle, with asexual and sexual development in the epithelium of the host gut and an environmental phase as an oocyst. All developmental stages vary greatly in their morphology and function, and therefore excrete different bioactive molecules for intercellular communication. Due to their complex development, we hypothesized that the extracellular vesicles (EVs) cargo is highly dependent on the life cycle stages from which they are released.
