Nesfatin-1/NUCB2, which is associated with the control of appetite and energy metabolism, was reported for the first time to be expressed in the hypothalamus. However, recent studies have shown that nesfatin-1/NUCB2 was expressed not only in the hypothalamus, but also in various tissues including digestive and reproductive organs. We also demonstrated that nesfatin-1/NUCB2 was expressed in the ...
Caprine arthritis encephalitis is a worldwide, multisystemic disease caused by a small ruminant lentivirus. Although the main route of transmission is oral, detection of proviral DNA of the caprine arthritis encephalitis virus (CAEV) in caprine semen has been previously described. However, the presence of viral antigens in the male reproductive tract has apparently never been reported. The obje...
Hormones are a vital component of reproductive processes, intimately acting on both sexes through proteins of pituitary origin that affect the gonads, and steroids of gonadal origin that affect the accessory organs and secondary sexual characters. Reproductive behavioral success is the capability of an organism to outcompete other organisms for a mate and to achieve copulation. Aside from its c...
Y chromosomes are different from other chromosomes because of a lack of recombination. Until now, complete sequence information of Y chromosomes has been available only for some primates, although considerable information is available for other organisms, e.g., several species of Drosophila. Here, we report the gene organization of the Y chromosome in the dioecious liverwort Marchantia polymorp...
Sexuality consists of three aspects that are interrelated and inseparable, biological, physiological and social. The biological aspect considers the individual’s capability to give and to receive pleasure. In consequence, it covers the functionality of the sexual organs and the physiology of human sexual response cycle. Diagnostic imaging modalities, such as single photon emission computed tomo...
Cryopreservation of male germ cells is a strategy to conserve animal species and strains of animals valuable to biomedical research. We tested whether mouse male germ cells could be cryopreserved without cryoprotection by simply freezing epididymides, testes, or whole bodies. The reproductive organs were isolated from killed mice and frozen for 1 week to 1 year at -80 degrees C before spermatoz...
Ticks are important vectors of numerous human diseases and animal diseases. Feeding stimulates spermatogenesis, mating and insemination of male factors that trigger female reproduction. The physiology of male reproduction and its regulation of female development are essentially a black box. Several transcriptomes have catalogued expression of tick genes in the salivary glands, synganglion and m...
Abstract Oilseed rape ( Brassica napus L.) is sensitive to heat stress during the reproductive stage, but it not clear whether male and female organs differ in their sensitivity stress. In this study, full diallel crossing experiments were conducted among four genotypes of B. under control, moderate high conditions for five days immediately before two after crossing. General combining ability (...
