This study found that among mother-infant pairs during the COVID-19 pandemic, lower maternal hair cortisol concentrations during pregnancy, combined with higher levels at six weeks postpartum, were associated with poorer infant developmental outcomes at six months.

This study found that blocking androgen receptors in male rats during the perinatal period led to permanently increased estrogen and ER-a expression in the hypothalamus, affecting sexual preference in adulthood.

This study suggests that Sonic hedgehog from hair follicles may support the proliferation of dentate neural stem cells in mice through transport by platelets during the perinatal period.

This study observed that hair cortisol levels increased during pregnancy and positively correlated with certain systemic cytokines postpartum, suggesting potential associations with perinatal outcomes.

Finasteride and DEHP exposure during development can change reproductive markers in rats.

This study reported that prenatal exposure to dihydrotestosterone altered long-term androgen metabolism in juvenile male rats, suggesting different regulatory mechanisms for 5a-reductase in hypothalamic versus pituitary tissues.

This study found that perinatal androgen deprivation in male rats increased serum estrogen levels and enhanced exploratory behavior, indicating that elevated estrogen may affect brain sex differentiation and related behaviors.

In this study, perinatal androgen deprivation in male rats led to elevated estrogen levels and a lack of sexual motivation towards gonadally-intact female rats.

This study observed that perinatal androgen deprivation in male rats increased serum estrogen levels, which was associated with improved spatial working memory and increased body weight.

This study constructed a comprehensive atlas of prenatal human skin, revealing that innate immune cells, such as macrophages, play a crucial role in skin morphogenesis by interacting with non-immune cells, influencing hair follicle formation and angiogenesis beyond their traditional immune functions.

This study found rapid changes in gene expression in mouse skin cells from the fetal to early postnatal stages, identifying specific markers for different fibroblast types and driver genes in dermal cell differentiation.

In this study, a missense mutation in the MAP2 gene was found to be associated with reduced hair follicle density, leading to the hairless phenotype in pigs.

This study reports that various surgical techniques for scalp reconstruction in children with hair loss at the Hair Clinic Poznan resulted in very good aesthetic outcomes and minimized complications.

In this study, researchers found that mast cells in Erythema Toxicum lesions in newborns are actively involved in the immune response around hair follicles, but do not express the antimicrobial peptide LL-37.

This review discusses the roles of mesenchymal stem cells in wound healing, particularly their interactions with immune cells, and highlights the potential and current limitations of MSC-based therapies for tissue regeneration.

This study indicated that the mineralocorticoid receptor (MR) plays a transient role in regulating epidermal differentiation during late embryonic stages, with glucocorticoid receptor (GR) potentially compensating for MR loss during the perinatal period.

This study found that prenatal exposure to finasteride in pregnant rats significantly disrupted male reproductive development, confirming its use as a positive control for androgen-related reproductive effects.

This review discusses the prenatal care guidelines for women with systemic lupus erythematosus and emphasizes the need for disease activity control to reduce maternal and fetal complications; it reports no new results.

This study observed that reduced in utero exposure to the neurosteroid allopregnanolone increased anxiety-like behavior in female guinea pigs during the juvenile period without affecting long-term allopregnanolone levels.

This case report describes a 2-month-old male with biotinidase deficiency whose seizures and skin symptoms improved dramatically with oral biotin supplementation.

In this case study, a 10-month-old minority infant from Xinjiang, China, with acrodermatitis enteropathy caused by an SLC39A4 gene mutation showed clinical improvement and increased zinc levels following zinc supplementation, highlighting the importance of early genetic testing and customized treatment in managing the disorder.

This review discusses sex differences in the neuroendocrine response to stress, focusing primarily on rodent studies, and highlights open questions about the roles of gonadal hormones and sex chromosomes.

This study found that testosterone and dihydrotestosterone are crucial for synaptic transmission and spine density in male hippocampal neurons, suggesting sex-specific effects of neurosteroids on brain development.

This case study reports a two and a half-month-old with biotinidase deficiency who showed rapid seizure improvement with biotin treatment after presenting with convulsions and neurological symptoms.

This case report describes a 12-year-old male dog with hepatoid cell carcinoma, showing significant health improvement after a month of bioregulatory therapy, including gastroenteropathy resolution, hair regrowth, and restored vision.

This article reviews the development, classification, and embryology of hypospadias and reports no new findings; the authors highlight its unknown cause and discuss associated anatomical anomalies.

This abstract reviews the characteristics and health risks associated with polycystic ovary syndrome and does not report new findings, highlighting the syndrome's multifactorial nature.

This study found that early life stress significantly affects hedonic sensitivity to high-palatable food by altering gonadal hormones in prenatally-stressed male and female rats, with sex-dependent changes in reward-related behaviors and neurochemistry.

This study found that neonatal administration of finasteride reduced sensitivity to alcohol's motor-stimulating effects and increased preference for novelty and initial alcohol consumption in rats, suggesting a role in alcohol vulnerability.

This study found that women with PCOS were more likely to have longer anogenital distances, indicating possible intrauterine origins linked to prenatal androgen exposure.
