Research progress of the role of Kisspeptin in puberty onset
Kisspeptin activates the hypothalamic-pituitary-gonadal axis (HPGA) and regulates the pulsatile secretion of gonadotropin-releasing hormone (GnRH) through KNDy neurons, thereby regulating the initiation of the pubertal phase. This review focuses on the mechanism of GnRH regulation by Kisspeptin and…

A cell line resistant to avian leukosis virus subgroup B infection
The expression of env proteins that bind to viral cell receptors on avian leukosis virus (ALV)-susceptible cells can block ALV infection. In this study, we constructed a cell line (DF-1/B) by expressing the ALV-B env protein in DF-1 cells. PCR, immune fluorescence assay, Western blot, and immune…

Optimization of Dry Deep Fractionation Process of Cottonseed Oil with PLC Temperature Control and Diaphragm Pressure Filtration and Evaluation of Its Cold Resistance Performance
Xinjiang cottonseed oil accounts for over 60% of China’s total domestic production. However, the content of long-chain saturated fatty acids such as palmitic acid in its fatty acid profile is as high as 21%~26%. This makes the oil prone to cloud and precipitate under the extremely low-temperature…

Median Effective Concentration of Ropivacaine for Femoral Nerve Block Maintaining Motor Function During Knee Arthroscopy in Two Age Groups
BACKGROUND: Femoral nerve block combined with general anesthesia is commonly used for patients undergoing knee arthroscopy in ambulatory care centers. An ideal analgesic agent would selectively (differentially) block sensory fibers, with little or no effect on motor nerves. Ropivacaine is…
