Effect of differences in residual feed intake on gastrointestinal microbiota of Dexin fine-wool meat sheep.

In this study, we examined the effects of different residual feed intakes (RFIs) on nutrient digestibility and the microbiota of the digestive tract of Dexin fine-wool sheep. Fifty 70-day-old Dexin fine-wool meat lambs were selected as the experimental group and fed in a single pen for 100 days. Based on their mid-term metabolic weight, 100-day average daily weight gain and daily feed intake, the male Dexin lambs were divided into a low-RFI group (13), a mid-RFI group (18), and a high-RFI group (11).

Effect of ellagic acid on body weight, nutrient digestibility, fecal microbiota, and urolithin A metabolism in Thoroughbred horses.

This study aimed to investigate the effects of ellagic acid (EA) supplementation on body weight (BW), nutrient digestibility, fecal microbiota, blood biochemical indices, and urolithin A metabolism in 1-yr-old Thoroughbred horses. A group of 18 1-yr-old Thoroughbred horses, with an average weight of 339.00 ± 30.

Combined Adsorption and Covalent Linking of Paclitaxel on Functionalized Nano-Graphene Oxide for Inhibiting Cancer Cells.

Developing targeted delivery nanosystems for delivering chemotherapeutic anticancer drugs specifically to cancerous tissues with improvement in the specificity of drugs for different cancer cells can result in high therapeutic efficacy and low toxicity in healthy tissues. Herein, we proposed the synthesis of a multifunctional nanodelivery system, folic acid (FA) decorating nanographene oxide (nGO) functionalized with poly(ethylene glycol) (PEG), called pGO-FA, with good biocompatibility and good delivering performance of a hydrophobic water-insoluble anticancer drug of paclitaxel (PTX). 4-br-PEG-NH, FA, and PTX were attached to PEG-functionalized nGO (pGO) through a combined chemical and physical force to form a nanosized complex, pGO-FA-PTX, defined as the nanodrug system.

Efficient nanobiocatalytic systems of nuclease P1 immobilized on PEG-NH2 modified graphene oxide: effects of interface property heterogeneity.

The use of graphene oxide (GO) nanosheets for functional enzyme support has attracted intensive interest owing to their unique planar structure and intriguing physical and chemical properties. However, the detailed effects of the interface properties of GO and its functionalized derivatives on active biomolecules are not well understood. We immobilize nuclease P1, a common industrial nucleic acid production enzyme, on pristine and amino poly(ethylene glycol) (PEG-NH2) modified GO nanosheets with interface property heterogeneity using two approaches, physical adsorption and chemical crosslinking.
