Puberty is a key stage in mammalian ontogeny, involving endocrinological, physiological and behavioural changes, moderated by intrinsic and extrinsic factors. Thus, not all individuals within one population achieve sexual maturity simultaneously.

Changes in gut microbiota composition with age and correlations with gut inflammation in rats
Increasing evidences indicate that gut microbiota composition is associated with multiple inflammatory diseases. However, little is known about how gut microbiota changes with age and correlations with gut inflammation at sexual maturity stage of healthy

Sexual maturity and shape development in cranial appendages of extant ruminants
Morphological disparity arises through changes in the ontogeny of structures; however, a major challenge of studying the effect of development on shape is the difficulty of collecting time series of data for large numbers of taxa.

Sexual maturation in Turkish boys
Ages of onset and attainment of various stages of secondary sexual characters were assessed from cross-sectional data on 1530 city schoolboys in Istanbul, Turkey. The subjects were grouped into four socio-economic classes. Ages of onset of pubic hair (11.80 years), axillary hair (13.15 years), facial hair (14.45 years) and laryngeal development (13.37 ...

Mature Modifications and Sexual Dimorphism [PDF]
Allometric growth between different parts of the shell often hampers the identification of mollusk shells, particularly in such cases where preadult shell growth varies strongly. Especially in gastropods, the terminal aperture is often less variable and yields morphological information essential for species determination (e.g. Vermeij 1993; Urdy et al.

ABSTRACT Primary cutaneous anaplastic large cell lymphoma (pcALCL) is a rare pediatric CD30‐positive T‐cell lymphoproliferative disorder with an excellent prognosis, but its genomic drivers are poorly defined. We report three children with skin‐limited disease demonstrating striking molecular heterogeneity, including NPM::ALK, NUP214::FRK, and a novel ...

Canonical correlation analysis applied to production and reproduction traits of meat type quails
: Data from 629 meat type quails were used to study association between two different sets of traits: egg production and reproduction. Traits related to reproduction were: body weight at 42 days (W42), average egg weight (AEW), age at sexual maturity ...
