We consider a class of seven-dimensional N = 1 supersymmetric orbifold GUTs in which the Standard Model (SM) gauge couplings and one of the Yukawa couplings (top quark, bottom quark or tau lepton) are unified, without low energy supersymmetry, at MGUT ≃ 4× 10 GeV. With gauge-top quark Yukawa coupling unification the SM Higgs boson mass is estimated to be 135± 6 GeV, which increases to 144± 4 Ge...

this experiment was conducted to examine effects of different levels of niacin on the gut and liver histology and also some activity of the liver enzymes in the blood serum of common carp. a control diet (containing 30 mg niacin kg-1 commercial diet) and four other diets were prepared which had 50, 70, 90 and 110 mg niacin per kg of commercial diet, added by spraying. fish with initial average ...

a total of 240, one-day-old quail chicks (coturnix coturnix japonica) were used to study the effects of artichoke leaf meal (alm) and vitamin e in diet on growth performance, ileal microbial populations and intestinal morphology in a 42-d trial. this experiment was performed as a completely randomized design with 4 replicates of 15 quails each, using a 4 × 2 factorial arrangement with diet and ...

Plumb Beach, Brooklyn, New York in USA is an important horseshoe crab breeding and nursery ground that has experienced substantial anthropogenic influence, including pollution, erosion and subsequent restoration. Since little is known about the relationship between sediment microbial communities and juvenile horseshoe crab survival, next generation sequencing was used to characterize and compar...

obesity: gut microbiota during development of obesity in cloned pigs DTU Orbit (18/06/2017) Changes in the gut microbiota of cloned and non-cloned control pigs during development of obesity: gut microbiota during development of obesity in cloned pigs Background Obesity induced by a high-caloric diet has previously been associated with changes in the gut microbiota in mice and in humans. In thi...

Studies in mice indicate that the gut microbiota promotes energy harvest and storage from components of the diet when these components are plentiful. Here we examine how the microbiota shapes host metabolic and physiologic adaptations to periods of nutrient deprivation. Germ-free (GF) mice and mice who had received a gut microbiota transplant from conventionally raised donors were compared in t...

Methanogenesis represents an important electron sink reaction in the hindgut of soil-feeding termites. This is the first comprehensive analysis of the archaeal community structure within the highly compartmentalized intestinal tract of a humivorous insect, combining clonal analysis and terminal restriction fragment (T-RF) length polymorphism (T-RFLP) fingerprinting of the archaeal communities i...

Eczema is a common skin condition that impairs children's daily life activities and quality of life. Previous research shows that gut microbiome composition plays an important role in the development of eczema. The present review summarizes evidence on environmental factors related to altered gut microbiota in children with eczema. We searched Medline, PubMed, Embase, and the Cochrane database ...

Glycosylation is an essential post-translational modification, which determines the function of proteins and important processes such as inflammation. β-1,4-galactosyltransferase I (βGalT1) is a key enzyme involved in the addition of galactose moieties to glycoproteins. Intestinal mucins are glycoproteins that protect the gut barrier against invading pathogens and determine the composition of t...

We analysed the spatio-temporal sequence of events concerning the morphology, physiology and ecology of the gut of piglets during the 2 weeks following weaning, in order to provide a limited number of variables that could be relevant markers of the gut post-weaning changes. An experiment was conducted on sixty piglets fasted for 2 d, then administered a weaning diet with a moderate or a high co...
