In “The Cutest Little Baby Face: A Hormonal Link to Sensitivity to Cuteness in Infant Faces,” Sprengelmeyer et al. (2009) reported results from three fascinating studies designed to test humans’ ability to discriminate among infants on the basis of cuteness. The first study indicated that women of reproductive age are superior to men and older women in this regard, and the second study revealed...

Many genes participate in the process of ovarian germ cell development, while the combined action mechanisms of these molecular regulators still need clarification. The present study was focused on determination of differentially expressed genes and gene functions at four critical time points in chicken ovarian development. Comparative transcriptional profiling of ovaries from embryonic day 5.5...

Ovulation has long been associated with an increased risk in ovarian cancer, yet the underlying molecular mechanisms remain obscure. Two aspects of ovulation have been linked to ovarian cancer pathogenesis. The first is the impact of repetitive tissue injury and repair that occurs with each ovulatory event. The second is the release of follicular fluid that accompanies the follicular rupture an...

introduction: the role of ovarian hormones and nitric oxide (no) in learning and memory and their interaction has been widely investigated. the present study carried out to evaluate different effect of l-name on spatial learning and memory of ovariectomized (ovx) and sham operated rats. methods: 32 rats were divided into 4 groups: 1) sham 2) ovx 3) sham-ln and 4) ovx-ln. the animals of groups 3...

Vasculogenic minicry (VM), an alternative blood supply modality except to endothelial cells-mediated vascular network, is a potential therapeutic target for ovarian cancer due to VM correlated with poor prognosis in ovarian cancer patients. Accelerated extracellular matrix (ECM) degradation is prerequisite for VM formation induced by epithelial-mesenchymal transition (EMT). Previous reports dem...

In fish as in other vertebrates, the diverse functions of thyroid hormones are mediated at the peripheral tissue level through iodothyronine deiodinase (dio) enzymes and thyroid hormone receptor (tr) proteins. In this study, we examined thyroid hormone regulation of mRNAs encoding the three deiodinases dio1, dio2 and dio3 - as well as three thyroid hormone receptors trαA, trαB and trβ - in init...

Circulating gonadal hormones have been linked to variation in the structure and function of adult human brain, raising question how cognition is affected by sex adulthood. The impacts progestogens estrogens are special interest due widespread use hormone supplementation. Multiple studies analyzed relationships between ovarian mental rotation performance, one largest known cognitive differences;...

Background. Hormone disorders, stress-oxidative and inflammation in ovarian tissue cause no- ovulation in women with polycyclic ovarian syndrome (PCOS). Several studies have shown the role of exercises in control of sex hormones. Objectives. The aim of this study was to investigate the effect of 6 weeks of swimming training (ST) on serum levels of sex hormones, antioxidant enzymes and oxidativ...
