Effects of a feed additive blend on broilers challenged with heat stress.

In conclusion, the feed additive blend protected intestines during heat stress from the decrease in villus height and crypt depth, and from the increase in villus width. Especially in the jejunum, heat stress played an important role by modulating oxidative stress and inflammation, impairing gut integrity and nutrient transport, and such deleterious effects were alleviated by the feed additive blend. RESEARCH HIGHLIGHTS Jejunum is the most sensitive intestinal segment during heat stress. Heat stress affects the expression of tight junctions and nutrient transporters. Feed management helps to alleviate the disturbances caused by heat stress. A blend of MCFA, organic acids and a polyphenol protects broilers under heat stress.

Abstract The dehydration reaction of tetraamino porphyrin and 4,4'-biphenyldicarboxaldehyde was performed for the synthesis of a novel covalent organic framework (COF), which was decorated on magnetic Fe3O4 to obtain core-shell structured Fe3O4@COFs nanospheres for the first time, for effective extraction and enrichment of sulfonamides (SAs). The morphology and structure of the synthesized nanospheres were characterized through various methods. The extraction conditions for six SAs including sulfadiazine, sulfamerazine, sulfamethazine, sulfamonomethoxine, sulfamethoxazole, sulfadimethoxine were systematically opti...

Discussion Athletes, whether recreational or competitive, who participate in weight sensitive sports commonly gain or lose weight to achieve a particular body type or to improve performance. Athletes in duration or aesthetic sports (such as distance running, diving, dance, etc.) attempting to lose weight to be able to move the body against gravity better. Sports that emphasize strength and power including combat sports (such as football, wrestling, mixed martial arts, body building, etc.) often have athletes attempting to gain weight and lean muscle mass to improve performance. This is felt to increase the strength-to-weig...

In this study, for developing a scaffold for tissue engineering from fish processing wastes, a hierachial collagen/gelatin/chitosan novel porous scaffold was fabricated using blends of collagen and gelatin extracted from the skins of Marine big eye snapper Priacanthus humrur. Scaffolds were developed by mechanical spinning of chitosan and by mixing of collagen and gelatin solutions followed by freeze drying and subsequent crosslinking of polymers. The scaffolds were evaluated for rheological properties – porosity, apparent density and swelling capacity to assess their mechanical property.Gelatin/chitosan composition ...

In this study, GO was mixed with poly(vinyl alcohol) (PVA) and used as a fiber precursor, which greatly improves the electrochemical properties. The above solution was uniformly coated onto the surfaces of gold chip to form GO NFs via electrospinning. AuNPs were coated onto the surface of GO NFs and then incorporated organic-inorganic hybrid nanoflower [Cu nanoflower-glucose oxidase (GOx) and horseradish peroxidase (HRP)]. The electrochemical experiments revealed that Cu-nanoflower@AuNPs-GO NFs exhibited outstanding electrochemical catalytic nature, and selectivity for the conversion of glucose to gluconic acid in the pres...

This study aimed to elucidate the mechanisms underlying the poor rejection of small pesticides by polyamide-based RO membranes. Rejection of the selected TOrCs (four N-nitrosamines and 158 pesticides) was primarily governed by size exclusion, charge interactions, and dipolar interactions when evaluated at high water temperatures. Further investigation indicated that small and uncharged secondary amide pesticides showed low and highly variable rejections, compared to similarly sized counterparts with no amide functional groups. Remarkably, three secondary amide pesticides that have no other atoms holding a high partial nega...
