This study suggests that the floral secretions of Brasiliorchis schunkeana may attract Diptera as potential pollinators, but field observations are needed to confirm this pollination syndrome.

This study found that hair cortisol levels in black-tailed prairie dogs, influenced by factors like predation risk and lactation, were associated with reproductive success, supporting the Cort-Adaptation hypothesis.

This study found that the peach gene CTG134, involved in auxin-ethylene interactions, plays a role in hormonal regulation during root hair formation in Arabidopsis and tobacco.

This study reports that hair samples can be used to track chronic hormone levels, revealing stress, reproductive, and sodium regulation patterns in wildebeest related to environmental factors.

This chapter reviews the biology and biochemistry of hormones involved in male sexual development and physiology, without reporting new research findings.

This study found that allopregnanolone has a bimodal effect on prolactin secretion in sheep, stimulating PRL mRNA expression but inhibiting hormone release under stress and pregnancy conditions.

This study observed that the binding of certain hormones in rat skin varies cyclically with the hair cycle phases, with testosterone showing maximum binding in the catagen phase.

In this study, researchers examined the genetic factors impacting cortisol and DHEA concentrations in the hair of healthy pigs; they found that cortisol levels were heritable and genetically correlated with behavioral stress responses, suggesting these hormones could potentially serve as indicators for selecting disease-resilient pigs.

This study found that in captive mouflon rams, reproductive and physical maturation, marked by changes in hormone levels and physical attributes, progresses gradually across their life span, with sexual maturity tied closely to physical maturity.

This study engineered a bioluminescent yeast strain responsive to androgenic chemicals, demonstrating rapid and sensitive detection suitable for high-throughput screening and environmental monitoring.

This study found that the cosmetic olfactory receptor agonist cyclohexyl salicylate may stimulate hair growth and expand stem cell progeny, suggesting potential as a cosmetic adjuvant for hair loss.

This study investigated the Mandarin duck as a model for understanding lifelong developmental changes, finding that male sail feather morphogenesis involves a combination of local morphogenetic programs, epigenetic regulation, and hormonal cues, with increased female estrogen levels observed before the mating season.

This study found that a specific amino-pyridine compound showed potent androgen receptor antagonist activity, stimulating hair growth in mice and reducing sebum production in a hamster model.

Male and female mice have different skin thickness, and hormones affect their skin and hair growth differently.

This study found that several new pregnane derivatives, especially steroids 16 and 19, demonstrated higher antiandrogenic activity on male hamster models than the commonly used finasteride.

In this study, melatonin administration enhanced various cellular and structural features of the scrotal skin in Soay rams, including increased thickness, cell count, and gland activity.

This study found that feather patterning is primarily self-organizing and dynamic, relying on both genetic and epigenetic controls, with implications for similar processes like fingerprints and pigmentation.

This study found that the pituitary gland is crucial for normal pelage color cycles in weasels, with certain hormones influencing regrowth of pigmented or white hair after molting.

This review discusses how the CRH/POMC systems may regulate human hair follicle pigmentation and highlights the concept of "self-similarity" in melanocortin systems at both local and systemic levels, without presenting new experimental results.

This study found that prenatal exposure to certain pesticides may lead to earlier breast development in girls, potentially associated with higher androgen levels.

This study found that host androgens like testosterone promote Staphylococcus aureus pathogenesis and skin infections by activating the agr quorum sensing system, revealing a mechanism for sex-dependent differences in these infections.

This study observed that circulating testosterone affects baseline sex differences in voiding function in C57BL/6J mice, with prostate lobe mass having a lesser impact.

This study found that steroid hormone levels in human hair correlate significantly with those in serum, suggesting hair may be a viable medium for assessing hormonal status.

The researchers reported that during early embryogenesis and larval development in Silurana tropicalis, inhibiting steroidogenic enzymes cyp19 and srd5beta affects genes related to thyroid and reproductive systems.

This research found that Leydig cells significantly rely on synthesizing omega-6 HUFAs to support male steroid hormone production, highlighting a new role for these fatty acids in the male reproductive system.

This study found that hair and nails can effectively measure hormone changes such as testosterone, estrogen, and progesterone during the peripubertal period in dogs, with variations observed between males and females at specific developmental stages.

This study established a protocol using anti-steroid antibodies to differentially label epidermal cell contributors, suggesting potential applications in simplifying complex trace DNA mixtures before profiling.

In this study, germ-free male mice showed altered levels of certain neuroactive steroids in the brain and periphery, suggesting microbiota may influence neuroendocrine pathways that support brain functioning.

This review explores the complex endocrine functions of human skin and its role as a peripheral endocrine organ, but reports no new clinical results.

This study developed and validated a comprehensive method using mass spectrometry to profile sex (pro)hormones in plasma, with results showing reliable calibration and detection of 31 analytes in samples from pre- and postmenopausal women and men, while addressing potential over- or underestimations in analyte concentrations.
