in this research, in order to develop new relationships with reasonable accuracy for estimation of the ‎submerged hydraulic jump characteristics, a study has been conducted experimentally. experiments have ‎been done in a rectangular channel with a length of 9 m, a width of 0.5 m and a depth of 0.45 m. froude ‎numbers in these tests range from 3.5 to 11.5 and between submergence ratios of 0.1 t...

The recently published article by Gadaleta and co-workers has demonstrated that activation of the bile acid (BA) nuclear receptor, Farnesoid X receptor a (FXR), affords multi-level protection against intestinal inflammation and inflammatory bowel disease (IBD) in mice. Of the numerous avenues of research into IBD diagnosis and treatment that are opened by these findings, the questions posed by ...

Weaning has been described as one of the most stressful events in the life of horses. Given the importance of the interaction between the gut-brain axis and gut microbiota under stress, we evaluated (i) the effect of two different weaning methods on the composition of gut microbiota across time and (ii) how the shifts of gut microbiota composition after weaning affect the host. A total of 34 fo...

Nonalcoholic fatty liver disease (NAFLD) is the most prevalent chronic liver disease in developed countries. Recent studies indicated that the modification of gut microbiota plays an important role in the progression from simple steatosis to steatohepatitis. Epidemiological studies have demonstrated consumption of fish oil or perilla oil rich in n-3 polyunsaturated fatty acids (PUFAs) protects ...

The gut microbiotas of zebrafish and mice share six bacterial divisions, although the specific bacteria within these divisions differ. To test how factors specific to host gut habitat shape microbial community structure, we performed reciprocal transplantations of these microbiotas into germ-free zebrafish and mouse recipients. The results reveal that communities are assembled in predictable wa...

The human distal gut hosts a bustling community comprising thousands of different kinds of bacteria. Fortunately, most of these intestinal residents don’t cause disease but instead play key roles in nutrition, metabolism, pathogen resistance, and immune response regulation. Unfortunately, these beneficial bacteria are just as susceptible to the antibiotics we take to treat pathogenic bacteria. ...

Preterm neonates have an immature gut and metabolism and may benefit from total parenteral nutrition (TPN) before enteral food is introduced. Conversely, delayed enteral feeding may inhibit gut maturation and sensitize to necrotizing enterocolitis (NEC). Intestinal mass and NEC lesions were first recorded in preterm pigs fed enterally (porcine colostrum, bovine colostrum, or formula for 20-40 h...

Changes in the relative abundances of many intestinal microorganisms, both those that naturally occur in the human gut microbiome and those that are considered pathogens, have been associated with a range of diseases. To more accurately diagnose health conditions, medical practitioners could benefit from a molecular, culture-independent assay for the quantification of these microorganisms in th...

Diet is one of the primary drivers that sculpts the form and function of the mammalian gut microbiota. However, the enormous taxonomic and metabolic diversity held within the gut microbiota makes it difficult to isolate specific diet-microbe interactions. The objective of the current study was to elucidate interactions between the gut microbiota of the mammalian herbivore Neotoma albigula and d...
