Reading hominin life history in fossil bones and teeth: methods to test hypotheses regarding its evolution

Biological Reviews, EarlyView.
ABSTRACT Human life history is derived compared to that of our closest living relatives, the great apes. It has been suggested that these derived traits are causally related to aspects of our ecology, social behaviour and cognitive abilities. However, resolving this requires that we know the evolutionary trajectory of our distinctive pattern of growth,

Prolactin-adjusted ACTH ratio in predicting lateralization of acth source during simultaneous bilateral inferior petrosal sinus sampling in patients with Cushing's disease

Indian Journal of Endocrinology and Metabolism, 2019
Introduction: Prolactin-adjusted adrenocorticotropic hormone (ACTH) ratio is used to improve the diagnostic accuracy of bilateral inferior petrosal sinus sampling (BIPSS) for lateralization of pituitary adenoma.

Uterine Notch2 facilitates pregnancy recognition and corpus luteum maintenance via upregulating decidual Prl8a2.

PLoS Genetics, 2021
The maternal recognition of pregnancy is a necessary prerequisite for gestation maintenance through prolonging the corpus luteum lifespan and ensuring progesterone production.

Duration and mode of delivery: Does maternal sleep matter?

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective Poor sleep quality in late pregnancy has been identified as a risk factor for operative deliveries. In this study, we investigated the associations between maternal sleep throughout pregnancy and its impact on both the duration and mode of delivery.

Endometrial Stromal Cell Senescence: A Non‐Negligible Factor in Recurrent Pregnancy Loss

iMetaMed, EarlyView.
As populations age, links between female reproductive aging and infertility are increasingly evident. Cellular senescence, characterized by near‐irreversible cell‐cycle arrest and accumulation of damage, can impair tissue function. In the endometrium, aberrant senescence of endometrial stromal cells (EnSCs) may compromise receptivity, hinder embryo ...

Variation in prolactin is related to variation in sexual behavior and contact affiliation. [PDF]

PLoS ONE, 2015
Prolactin is associated with both maternal and paternal care and appears important in developing a bond between parent and infant. In contrast with oxytocin, another hormone important in infant care, there is scant information on the role of prolactin in

Steroidopathies and hormonal imbalance in children and adolescents with autism spectrum disorder

JCPP Advances, EarlyView.
Abstract Background Autism Spectrum Disorder (ASD) is a complex neurodevelopmental condition with a multifactorial etiology, many aspects of which remain unclear. Emerging evidence suggests a potential association between ASD and clinical manifestations resulting from hormonal imbalances, henceforth named “steroidopathies.” The present study aims to ...

Prolactin and cancer: Has the orphan finally found a home?

Indian Journal of Endocrinology and Metabolism, 2012
Prolactin has, for long, been associated with galactorrhea and infertility in women while its role in men is largely unknown. Recently, expression of prolactin in various other tissues like the breast, prostate, decidua, and the brain has been recognized.

Molecular Investigations on Angiogenesis and Oxidative Stress in Roe Deer (Capreolus capreolus) Bucks' Testes Throughout the Reproductive Cycle

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Animals with seasonal reproductive cycles, as the Roe deer (Capreolus capreolus), have developed mechanisms to synchronize reproduction with the environmental cycle in order to optimize reproductive success through melatonin. Angiogenesis and oxidative stress are key processes in spermatogenesis, contributing to testicular remodeling and ...

Prolactin – friendly lactation hormone or hostile cancerogenic factor?

Journal of Education, Health and Sport, 2019
Prolactin is a hormone secreted by lactotrophic cells of the pituitary gland and its main function is stimulating lactation. Binding prolactin by its membrane receptor leads to the activation of signalling pathway that enables cell proliferation and ...
