All organisms with sexual reproduction undergo a process of mating, which essentially involves the encounter of two individuals belonging to different sexes. During mate search, both sexes should mutually optimize their encounters, thus raising a question of how they achieve this. Here, we show that a population with sexually dimorphic movement patterns achieves the highest individual mating su...

A sample of 460 low-income women completed a mate preference questionnaire and surveys that assessed family background, life history, conscientiousness, sexual motives, self-ratings (e.g., looks), and current circumstances (e.g., income). A cluster analysis revealed two groups of women: women who reported a strong preference for looks and money in a short-term mate and commitment in a long-term...

Differentiation and secondary metabolism are correlated processes in fungi that respond to light. In Aspergillus nidulans, light inhibits sexual reproduction as well as secondary metabolism. We identified the heterotrimeric velvet complex VelB/VeA/LaeA connecting light-responding developmental regulation and control of secondary metabolism. VeA, which is primarily expressed in the dark, physica...

Contaminants of emerging concern (CECs) in treated municipal effluents have the potential to adversely impact exposed organisms prompting elevated public concern. Using transcriptomic tools, we investigated changes in gene expression and cellular pathways in the liver of male fathead minnows (Pimephales promelas) exposed to 5% concentrations of full secondary-treated (HTP) or advanced primary-t...

BACKGROUND Puberty is a complex and dynamic period in development during which individuals transition from the juvenile to adult state. Regulated by multiple genetic and endocrine controls, it is characterized by somatic growth and sexual maturation. Sexual precocity is defined as the appearance of secondary sexual characteristics before the lower limit of the normal age for pubertal onset. D...

We herein present a case of a 27-year-old woman with all features of secondary amenorrhea and secondary sexual characteristics.

Chromosome aberrations or genetic syndromes associated with cloacal-bladder exstrophy complex have rarely been reported. The aim of this report is to describe a 14 year-old female Brazilian patient with a complex urogenital malformation, short stature, lack of secondary se-xual characteristics and Y chromosome aberration. A girl with cloacal bladder exstrophy complex was referred for evaluation...

BACKGROUND Numerous health problems are initiated in childhood and adolescence. For example, obesity, which has increased significantly in recent years, often begins in early life. The objective of this study is to describe social inequalities in obesity and other health problems among adolescents, by sex. METHODS Data were from a cross-sectional study conducted in a representative sample of ...

The purpose of the present study was to examine gender differences in perceptions of basic psychological needs support from the teacher and peers in physical education. The 659 Estonian secondary school students (310 boys and 349 girls; M age=13.57 years, SD=0.62) completed questionnaires assessing the perceptions of autonomy, competence, and relatedness need support from both the teacher and p...

Purpose: This study aimed to analyze rumination levels of transsexual women before and after gender affirmation surgery (GAS). Rumination scores may represent a broader measure of GAS success and an alternative to patient-reported satisfaction, quality of life, well-being, or the presence of "caseness" for anxiety or depression as previously established in the literature. Methods: Thirty-nine t...
