Enhancing the production of aquatic animals is crucial for fishery management and aquaculture applications. Ovaries are specialized tissues that play critical roles in producing oocytes and hormones. Significant biochemical changes take place during the sexual maturation of Portunus trituberculatus, but the genetics of this process has not been extensively studied. Transcriptome sequencing can ...

The concentrations of the adrenal steroids dehydroepiandrosterone (DHA), dehydroepiandrosterone sulfate (DHAS), and delta 4-androstenedione (delta 4-A) have been measured by RIA before and after sexual maturation in plasma of rodents, domestic animals, and primates to determine whether these species exhibit and adrenarchal process comparable to man. The average concentrations of DHA and DHAS we...

The objective of this study was to assess the longitudinal changes in blood pressure in black and white adolescent girls and evaluate potential determinants of changes in blood pressure, including sexual maturation and body size. A total of 1213 black and 1166 white girls, ages 9 or 10 years at study entry, were followed up through age 14 with annual measurements of height, weight, skinfold thi...

BACKGROUND There is limited data on sexual maturation among girls with intellectual, sensory, or physical disabilities. OBJECTIVES The present cross-sectional study was conducted to assess the sexual maturation of girls with these disabilities in special schools. METHODS In this cross-sectional study, we evaluated the onset and progression of sexual maturation in 642 six to 18-year-old girl...

The dyslipidemia associated with excess weight is a risk profile global call for cardiovascular disease (CVD). The aim of this study was to investigate the association between dyslipidemias and other risk factors for cardiovascular diseases (CVD) in adolescents, considering sexual maturation. A cross-sectional study was carried out with 432 adolescents from public schools, aged 10-19 years. The...

OBJECTIVE The neonatal and/or prepubertal androgen milieu affects sexual maturation. In rodents, neonatal chronic testosterone treatment, which is used as a model of polycystic ovary syndrome (PCOS), results in the onset of vaginal opening occurring earlier in the pubertal period. DESIGN In the present study, the changes in hypothalamic Kiss1 (a gonadotropin-releasing hormone (GnRH)-stimulati...

Photoperiod, or length of day, has a predictable annual cycle, making it an important cue for the timing of seasonal behavior and development in many organisms. Photoperiod is widely used among temperate and polar animals to regulate the timing of sexual maturation. The proper sensing and interpretation of photoperiod can be tightly tied to an organism's overall fitness. In photoperiodic mammal...

A newly developed Semantic Misattribution Procedure (SMP), a semantic variant of the Affect Misattribution Procedure (AMP), was used in three studies as an indirect measure of sexual interest. Using a known-group approach, homosexual men (Study 1 & 2), heterosexual men (Study 1 to 3) and heterosexual women (Study 3) were asked to guess the meaning of briefly presented Chinese ideographs as “sex...

In the present work, histochemical and biochemical studies were conducted to analyze changes in the pattern of autonomic innervation during sexual maturation, using the rat epididymis as a model. Glyoxylic acid histochemistry and immunohistochemical studies against dopamine beta-hydroxylase (DbetaH) and acetylcholinesterase (AChE) indicated a reduction in the amount of catecholaminergic and ACh...
