RFamide-related peptide-3 (RFRP-3) has been proposed as a key inhibitory regulator of mammalian reproduction. To further determine the potential mechanisms and sites of action of RFRP-3, we systematically investigated the direct effect of RFRP-3 on the female pig reproductive axis in vitro. Initially, we confirmed that G protein-coupled receptor 147(More)
Heat stress can cause systemic physiological and biochemical alterations in living organisms. In reproductive systems, heat stress induces germ cell loss and poor quality semen. However, until now, little has been known about such a complex regulation process, particularly in the perspective of metabolism. In this study, serum, hypothalamus, and epididymis(More)
Criminal geographical profile is a methodology of investigation, which makes use of correlation between crime location and crime base of criminal to find out the most probable place of the crime base. We introduce a model to predict the future serial crime location with aid of criminal geographic profiling and the time and locations of past crime scenes. In(More)
Gonadotropin-inhibitory hormone (GnIH), a key regulator of vertebrate reproduction, was identified in the Japanese quail in 2000, and RFamide-related peptide-3 (RFRP-3) was found to be a mammalian GnIH ortholog. To further determine its role in the reproductive system of male Xiaomeishan pigs, we systematically investigated changes in GnIH and its receptors(More)
Neuropeptide W (NPW), a novel hypothalamic peptide, is an endogenous ligand for the orphan G protein-coupled receptors GPR7 (NPBWR1) and GPR8 (NPBWR2). Although several studies have implicated NPW in the regulation of feeding and energy metabolism in many species, the precise physiological function of NPW in pigs remains unclear. In this study, we cloned(More)
Neuromedin U (NMU) is a highly conserved neuropeptide that performs a variety of physiological functions in animals via neuromedin U receptor-1 (NMUR1) and neuromedin U receptor-2 (NMUR2). In this study, we cloned the pig NMU, NMUR1 and NMUR2 genes. Bioinformatics analysis demonstrated that the pig NMU cDNA encoded the amino acids(More)
This paper analyzes the unreasonable relationship between the growths of revenue and decrease of profit. Then, using the operating model of Apple and other successful foreign operators' cases, it points out that the intellectualization would be the only way for Chinese telecom operators. This paper makes use of the Smart Pipe structure and the contrast(More)
Kisspeptin is a peptide encoded by the Kiss 1 gene and is also called metastin. Previous studies have generally focused on several functions of this peptide, including metastasis, puberty, vasoconstriction and reproduction. However, few studies have focused on the cardiac functions of kisspeptin. In the present study, cardiac histomorphology was observed(More)
Neuromedin B is one member of a family of bombesin-like peptides, which performs a variety of physiological functions via their receptor (NMBR) in most mammals. However, the genes encoding NMB and NMBR and their functions especially reproduction of the pigs are currently not fully understood. To research the physiological functions of NMB, we cloned and(More)
