[Protective effects of salidroside on vascular endothelial cells in rats with frostbite after chronic hypoxia].

To investigate the protective effects of salidroside on endothelial cells in rats with frostbite after chronic hypoxia. Healthy male SD rats, randomly divided into 3 groups with 10 rats in each group, which included the sham injury group, the model group, and the model +salidroside group. The rats in each group were placed in a composite low-pressure chamber to simulate a environment with a pressure of 54.

Effect of Yak Meat to the Daily Ration of Scalded Rats for Wound Healing.

Objective: Treatment of burn wound healing involves infection, nutrition, psychology and rehabilitation, and proper nutritional support can promote wound healing, enhance immune function and reduce the incidence of complications. This study aimed to investigate the effects of feed containing yak meat on scalded rats' body condition and wound healing.

Methods: Adopting a two-factor factorial design, the growth performance, food intake, body weight, and Lee's index of rats were measured.

miRNAs expression profile in bast of ramie elongation phase and cell wall thickening and end wall dissolving phase.

MicroRNAs (miRNAs) are 20-24 nucleotide long non-coding RNAs that play critical regulatory roles during plant development, organ morphogenesis, and cell fate determination and differentiation. In this study, miRNA microarray chips were used to explore the expression profile of ramie miRNAs between the bast of fiber elongation phase and those of cell wall thickening and end wall dissolving phase. There are 150 and 148 credible miRNAs in the bast of fiber elongation phase and cell wall thickening and end wall dissolving phase, respectively.

Cloning and expression profiling of the VLDLR gene associated with egg performance in duck (Anas platyrhynchos).

Background: The very low density lipoprotein receptor gene (VLDLR), a member of the low density lipoprotein receptor (LDLR) gene family, plays a crucial role in the synthesis of yolk protein precursors in oviparous species. Differential splicing of this gene has been reported in human, rabbit and rat. In chicken, studies showed that the VLDLR protein on the oocyte surface mediates the uptake of yolk protein precursors into growing oocytes.

[Expression of cyclin-dependent kinase 2-associated protein 1 in chicken embryos of different sexes].

To investigate the expression and functions of cyclin-dependent kinase 2-associated protein 1 (cdk2ap1) screened by suppression subtractive hybridization in chicken embryo development, a pair of primers was designed to amplify the cdk2ap1 fragment by RT-PCR and subsequently the fragment obtained was cloned into the plasmid pGEM-T. Sense and antisense probes labeled with digoxigenin were generated using SP6 and T7 RNA polymerases, respectively, and used to examine cdk2ap1 expression in chicken embryos of both sexes by whole-mount in situ hybridization. In both sexes, cdk2ap1 was expressed in the head mesenchyme, rhombencephalon, optic vesicles, spinal neural tube, and forelimb of 4.
