Kresoxim-methyl (KM) is a broad spectrum strobilurin fungicide that has been used widely on crops around the world. In the present study, we aimed to investigate the toxic effects of KM using various sublethal endpoints during zebrafish (Danio rerio) larval development. Results showed that the LC values of KM to zebrafish at multiple life stages (embryo, larvae, juvenile and adult) were 0. Read More

In females, a hallmark of puberty is the luteinizing hormone (LH) surge that triggers ovulation. Puberty initiates estrogen positive feedback onto hypothalamic circuits, which underlie the stimulation of gonadotropin releasing hormone (GnRH) neurons. In reproductively mature female rodents, both estradiol (E2) and progesterone (P4) signaling are necessary to stimulate the surge release of GnRH and LH. Read More

Strigolactones (SLs) are a family of terpenoid allelochemicals that were recognized as plant hormones only a decade ago. They influence a myriad of both above- and belowground developmental processes, and are an important survival strategy for plants in nutrient-deprived soils. A rapidly emerging approach to gain knowledge on hormone signaling is the use of traceable analogs. Read More

Prostate specific membrane antigen (PSMA) may be targeted for both diagnostic and therapeutic purposes in the management of prostate cancer (PCa). In pre-clinical models, androgen blockade (AB) increases expression of PSMA in both hormone sensitive and castrate resistant xenotypes. The aim of this study was to evaluate the effect of AB treatment on Ga68PSMA-11 PET imaging in hormone naive (Luteinising hormone-releasing hormone (LHRH) ± bicalutamide), and in castrate resistant men (enzalutamide or abiraterone) with metastatic PCa.

In breast cancer cells, some topologically associating domains (TADs) behave as hormonal gene regulation units, within which gene transcription is coordinately regulated in response to steroid hormones. Here we further describe that responsive TADs contain 20- to 100-kb-long clusters of intermingled estrogen receptor (ESR1) and progesterone receptor (PGR) binding sites, hereafter called hormone-control regions (HCRs). In T47D cells, we identified more than 200 HCRs, which are frequently bound by unliganded ESR1 and PGR. Read More

The juvenile hormones (JHs) are a family of insect acyclic sesquiterpenoids produced by the corpora allata (CA), a pair of endocrine glands connected to the brain. They are involved in the regulation of development, reproduction, behavior, caste determination, diapause, stress response, and numerous polyphenisms. In the post-genomics era, comprehensive analyses using functional 'omics' technologies such as transcriptomics, proteomics and metabolomics have increased our understanding of the activity of the minute CA.

Insects utilize an open circulatory system to transport nutrients, waste, hormones and immune factors throughout the hemocoel. The primary organ that drives hemolymph circulation is the dorsal vessel, which is a muscular tube that traverses the length of the body and is divided into an aorta in the head and thorax, and a heart in the abdomen. The dorsal vessel is myogenic, but its rhythmicity is modulated by neuropeptides and neurotransmitters. Read More

Juvenile hormone (JH) has both gonadotropic and non-gonadotropic roles in eusocial insects. There is controversy over whether the non-gonadotropic role is novel, related specifically to social evolution, or is a second conserved role. Study of subsocial insects suggests that when JH is non-gonadotropic, the specific associations of high JH, low vitellogenin, suppressed ovarian development and elevated metabolism may parallel those in workers of eusocial insects.

Enhancing testosterone production in males is a continuous research direction for many scientists in the field, due to its role as a principal sex hormone and as a crucial modulator of well-being and general health in humans. Since 1978, there have been more than 30 studies that have connected coenzyme Q and testosterone. Such a link is attributable to the vigorous biological role of coenzyme Q as a crucial member in the energy production route in humans and animals, which is thought to have a positive influence on testosterone production, and hence on infertility, particularly male infertility.

Hormonal dynamics after infection were compared in two cultivars-more resistant SY Alister and more sensitive Hornet, in order to elucidate responses associated with efficient defense. Both cultivars responded to infection by the early transient elevation of active cytokinins (predominantly -zeatin) and auxin indole-3-acetic acid (IAA) in leaves and roots, which was longer in Hornet. Moderate IAA levels in Hornet roots coincided with a high expression of biosynthetic gene (contrary to , , ). Read More

Recommendations presented are evidence-based, insofar as this is possible, given that the levels of evidence are weak or moderate due to small sample sizes and nonuniform diagnostic criteria used in many studies. High-grade endometrioid carcinomas include FIGO grade 3 endometrioid carcinomas, serous carcinomas, clear cell carcinomas, undifferentiated carcinomas, and carcinosarcomas. Read More

The primary function of the female reproductive tract (FRT) is to enable successful reproduction, yet the biologic mechanisms required to accomplish this, which include fluctuating sex hormones and tolerance of semen and a semi-allogeneic fetus, can leave this unique mucosal environment susceptible to pathogenic challenge. Consequently, the FRT has evolved specialized innate and adaptive immune responses tailored to protecting itself from infection without compromising reproductive success. A family of innate immune cytokines that has emerged as important regulators of these immune responses is the type I IFNs. Read More

Endurance champions may have 40% more RBCV than controls and RBCV may increase up to 10% following months of regular exercise training in healthy individuals. Read More
