Sex-specific costs of rearing a nestling and its implications in the brood sex ratio of Magellanic penguins
(Springer, 2021-08)
In birds, possible explanations for a bias in brood sex ratio include differential cost of rearing nestlings of different sexes, and different parental fitness returns related to offspring sex. We studied brood sex ratio ...
Sex differences in body fluid homeostasis: Sex chromosome complement influences on bradycardic baroreflex response and sodium depletion induced neural activity
(Pergamon-Elsevier Science Ltd, 2015-12)
Clinical and basic findings indicate that angiotensin II (ANG II) differentially modulates hydroelectrolyte and cardiovascular responses in male and female. But are only the activational and organizational hormonal effects ...
Blow flies, synanthropy and sex ratio: are the deviations in the sex proportion linked to human transformation of landscapes?
(Elsevier Science, 2021-07)
In most species, several factors like time of emergence, age at maturation, reproductive life span, survival of males and females, mating behavior, differential resource use, and migration patterns may affect the adult sex ...
Estradiol-dependent axogenesis and Ngn3 expression are determined by XY sex chromosome complement in hypothalamic neurons
(Nature Research, 2020-12)
Hypothalamic neurons show sex differences in neuritogenesis, female neurons have longer axons and higher levels of the neuritogenic factor neurogenin 3 (Ngn3) than male neurons in vitro. Moreover, the effect of 17-β-estradiol ...
Empathy, sex and fluid intelligence as predictors of theory of mind
(Elsevier, 2013-04)
Individual differences in theory of mind (ToM) are affected by a variety of factors. We investigated the relationship between empathy, sex and fluid intelligence (FI) as predictors of ToM in a random probabilistic sample ...
Determining Sex of Magellanic Penguins Using Molecular Procedures and Discriminant Functions
(Waterbird Society, 2002)
Kinetic activity of the sex chromosomes of Mormidea paupercula (Pentatomidae, Heteroptera)
(Czech Academy of Sciences, 2010-07)
InMormidea paupercula (n = 6 + XY in males), the presence of a CMA3-bright band in the telomeric regions on both sexchromosomes allowed the analysis of the kinetic activity of the sex univalents and XY pseudobivalent at ...
Gonadal hormone-independent sex differences in GABAA receptor activation in rat embryonic hypothalamic neurons
(Wiley Blackwell Publishing, Inc, 2020-03)
Background and Purpose: GABAA receptor functions are dependent on subunit composition, and, through their activation, GABA can exert trophic actions in immature neurons. Although several sex differences in GABA-mediated ...
Does gender leave an epigenetic imprint on the brain?
(Frontiers Media S.A., 2019-02)
The words “sex” and “gender” are often used interchangeably in common usage. In fact, the Merriam-Webster dictionary offers “sex” as the definition of gender. The authors of this review are neuroscientists, and the words ...
Postprandial glycemic response in different bakery formulations with adequate palatability: Sex-related effects
(Emerald, 2021-08)
Purpose: Hyperglycemic diets are a critical risk factor for diabetes and other chronic diseases; therefore, food innovation is encouraged. In this sense, starchy foods with a better postprandial glycemic response (PGR) ...
