The reproductive success of sibling cocklebur plants (Compositae: Xunthium strumarium) was monitored after growth at different levels of availability of water and nutrient resources. Variation in reproductive success among individual plants was related to physiological, structural, and phenological characteristics. Reproductive success increased with increased availability of resources, but the...
Salvia miltiorrhiza bunge(SM) is a popular herb for alleviating menopausal symptoms, although the scientific evidence of applying SM to estrogen replacement therapy is limited. In this study, we characterized the estrogenic activity of SM using in vivo models of immature and ovariectomized (OVX) mice and performed in vitro studies focusing on the estrogen receptor (ER) pathway for further molec...
Testing the optimal defense hypothesis in nature: Variation for glucosinolate profiles within plants
Plants employ highly variable chemical defenses against a broad community of herbivores, which vary in their susceptibilities to specific compounds. Variation in chemical defenses within the plant has been found in many species; the ecological and evolutionary influences on this variation, however, are less well-understood. One central theory describing the allocation of defenses in the plant i...
Transglutaminases are a family of enzymes that are known for their protein cross-linking abilities. Transglutaminases have been investigated very little in female reproductive tissues. We hypothesized that transglutaminase proteins were present and active in the virgin rat uterus and cervix. In both tissues, real time RT-PCR identified transglutaminase 1, 2, 3, and 4 mRNA, and immunohistochemis...
Zika virus (ZIKV), an emerging flavivirus, has recently spread explosively through the Western hemisphere. In addition to symptoms including fever, rash, arthralgia, and conjunctivitis, ZIKV infection of pregnant women can cause microcephaly and other developmental abnormalities in the fetus. We report herein the results of ZIKV infection of adult rhesus macaques. Following subcutaneous infecti...
Many anatomical differences exist between males and females; these are manifested on a molecular level by different hormonal environments. Although several molecular differences in adult tissues have been identified, a comprehensive investigation of the gene expression differences between males and females has not been performed. We surveyed the expression patterns of 13,977 mouse genes in male...
Cadmium (Cd) is one of the most toxic environmental heavy metals to organisms. The prominent toxic effects of Cd on reproductive organs are very well known. Gonad histopathology is a valuable tool for the assessment of endocrine disruption compounds EDCs effects on fish. The aim of this study was to evaluate the reproductive toxicity of cadmium chloride (CdCl2) on histopathology of Zebrafish (D...
Background: There is a rapidly growing trend in the consumption of herbal remedies in the developing countries. The Phoenix dactylifera date palm pollen (DPP) is used in the traditional medicine for male infertility. The aim of this study was to determine the effects of orally administered DPP on the reproductive system of adult male rats. Methods: Fifty Sprague-Dawley rats were maintained acco...
Background and purpose: Multiple line of evidence suggested that diabetes has adverse effects on male sexual and reproductive functions. The aim of present study was to investigate the protective effect of colostrum (COL) on sperm parameters, sex hormones, testes histopathological changes, and oxidative stress in diabetic rats. Materials and methods: In this experimental study, 30 diabetic m...
