Heterochrony of puberty in the European badger (Meles meles) can be explained by growth rate and group-size: Evidence for two endocrinological phenotypes.

open access: yesPLoS ONE, 2019
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

open access: yesPLoS ONE, 2022
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

Identification of the TSSK4 Alternative Spliceosomes and Analysis of the Function of the TSSK4 Protein in Yak (Bos grunniens)

open access: yesAnimals, 2022
In mammals, the testis-specific serine/threonine kinase (TSSK) is essential for spermatogenesis and male fertility. TSSK4 belongs to the family of the testis-specific serine/threonine-protein kinase (TSSK), with a crucial role in spermatogenesis.

Sexual maturity and shape development in cranial appendages of extant ruminants

open access: yesEcology and Evolution, 2016
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

open access: yesAnnals of Human Biology, 1975
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]

open access: yes, 2015
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.

Genomic Diversity and Clinical Variability in Pediatric Primary Cutaneous Anaplastic Large Cell Lymphoma: A Case Series

open access: yesPediatric Blood &Cancer, EarlyView.
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

open access: yesCiência Rural, 2016
: 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 ...
