Chromosome mapping of repetitive sequences in Anostomidae species: Implications for genomic and sex chromosome evolution
(2012-12-01)
Background: Members of the Anostomidae family provide an interesting model system for the study of the influence of repetitive elements on genome composition, mainly because they possess numerous heterochromatic segments ...
Population dynamics, sex ratio and size at sex change in a protandric simultaneous hermaphrodite, the spiny shrimp Exhippolysmata oplophoroides
(Springer, 2010-12-01)
One of the main goals of sex allocation theory is understanding sex ratio evolution. However, theoretical studies predicting sex ratios in species with unusual sexual systems, such as protandric simultaneous (PS) ...

Proteomic profile of sex-sorted bull sperm evaluated by SWATH-MS analysis
(2018-11-01)
The identification of distinct proteins present on the membrane of spermatozoa with X and Y chromosomes allows the development of immuno-sexing techniques. The aim of this study, therefore, was to use mass spectrometry to ...

STIM and Orai proteins: players in sexual differences in hypertension-associated vascular dysfunction?
(PORTLAND PRESS LTD, 2010)
Sex-associated differences in hypertension have been observed repeatedly in epidemiological studies; however, the mechanisms conferring vascular protection to females are not totally elucidated. Sex-related differences in ...
COVID-19 and Sex Differences: Mechanisms and Biomarkers
Men are consistently overrepresented in Severe Acute Respiratory Syndrome Coronavirus 2
(SARS-CoV-2) infection, and COVID (COrona- VIrus-Disease)-19 severe outcomes, including

Determination of equine fetal sex by Doppler ultrasonography of the gonads
(Wiley-Blackwell, 2014-11-01)
Reasons for performing the studyThe identification of fetal sex in horses by location of the genital tubercle between 55 and 70 days of pregnancy is hampered by the large amount of allantoic fluid, extensive fetal movements ...
Crosstalk Between Retinoic Acid and Sex-Related Genes Controls Germ Cell Fate and Gametogenesis in Medaka
(Frontiers Media Sa, 2021-01-18)
Sex determination (SD) is a highly diverse and complex mechanism. In vertebrates, one of the first morphological differences between the sexes is the timing of initiation of the first meiosis, where its initiation occurs ...
