This study found that, despite a major depletion of SOX2-expressing stem cells in the pituitary, there was no effect on endocrine cell homeostasis or response to certain stressors in adult mice.

This review summarizes recent research into the effects of GLP-1 receptor agonists on skin processes, noting potential benefits for wound healing but also potential cosmetic concerns like facial fat loss and decreased collagen, highlighting the need for more clinical studies to clarify their dermatological impact.

This review highlights that hormones significantly influence the wound healing process by coordinating cellular and molecular activities, and hormonal therapy is emerging as a promising treatment, with current research focusing on optimizing dosages and minimizing side effects.

This study found that female adolescents with pilonidal sinus disease had significantly higher insulin levels and HOMA-IR scores, suggesting hyperinsulinemia may be a risk factor for the condition.

This study found that hypothyroidism in women with PCOS significantly increased insulin resistance and obesity, which might worsen metabolic issues and impact conditions like hair loss and infertility.

This article discusses differences in hair loss among monozygotic female twins despite identical genetics and reports no new clinical findings.

This research abstract provides no results, focusing on the equal contributions of the authors in the field of molecular, cellular, and developmental biology from Yale University.

This review discusses how acute exposures to environmental and internal stressors can quickly alter skin functions, leading to various dermatological symptoms, and calls for more research on these short-term effects.

This study used multi-omics analysis to explore how wheat roots adapt to temperature stress, revealing that distinct hormonal signaling pathways are linked to iron homeostasis and drive root morphological changes, supporting the idea of an 'iron-dependent hormonal trade-off' model.

This study found that humanized mouse models expressing mutated or reduced levels of the vitamin D receptor were able to maintain normal mineral homeostasis and prevent typical symptoms of vitamin D resistance.

This review discusses the plasticity of stem cell populations and their ability to switch between functions for tissue homeostasis and regeneration, emphasizing environmental and hormonal influences, and reports no new results.

In this study, a very low-calorie ketogenic diet significantly improved metabolic and hormonal profiles in obese men, but did not significantly enhance most semen parameters except for sperm motility.

This chapter discusses various skin functions and structures involved in protection, immune response, and homeostasis, but it reports no new research findings.

This animal study found that testosterone treatment increased vas deferens fluid secretion rate in rats, with potential implications for male fertility through the upregulation of AQP-1, 2, and 9 proteins.

This study explores the correlation between sirtuins' expression, histone deacetylation, and redox status in young and old monozygotic twins to understand their role in age-related mechanisms.

This study explored how root hairs integrate opposing growth signals but did not report new conclusive findings on the activation of known molecular players in polar growth.

The skin's layers protect, sense, and regulate the body's internal balance, but can be prone to cancer.

This scoping review evaluates the connection between hypoxia and declining sex hormonal signaling in middle-aged individuals, proposing a "middle-aging hypovascularity hypoxia hypothesis" as a potential mechanism influencing age-related diseases, with implications for developing strategies to maintain healthspan.

This study found that metformin's metabolic benefits, such as reducing fat content and improving insulin sensitivity, were less pronounced in men with early-onset androgenic alopecia compared to those with normal hair growth, possibly due to differences in systemic inflammation and vitamin D status.

In this narrative review, the authors observed that prolonged stress, by increasing cortisol and affecting androgenic hormones, can harm hair follicles, leading to inflammation and worsening of alopecia areata and androgenetic alopecia.

In this study, treatment with insulin sensitizers significantly increased adipose tissue GLUT4 mRNA expression and improved insulin resistance, menstrual patterns, and androgen profiles in PCOS patients, with rosiglitazone being more effective than metformin.

This study observed two distinct phenotypes among North Indian women with PCOS: obese hyperinsulinaemic dysglycemic women from Delhi and lean hyperandrogenic women from Srinagar, despite being in the same region.

The study discusses how stress can lead to telogen effluvium, a form of hair loss, by triggering hormonal imbalances and affecting microcirculation and hair follicle homeostasis. It highlights both medicinal and non-medicinal interventions, such as relaxation techniques and gentle care rituals, as potential treatment strategies.

This chapter discusses the role of hormones in regulating reproductive biology and outlines how the endocrine system, particularly the brain and pituitary gland, controls these hormonal processes.

This study elucidates a mechanism for male pattern baldness involving chronic scalp tension leading to follicular hypoxia, rather than purely hormonal factors, and proposes a treatment targeting electrolyte, vascular, and neurological factors to restore balance.

This study elucidates a mechanism for male pattern baldness involving tension in scalp muscles that leads to reduced blood flow and hypoxia around hair follicles, proposing a multi-targeted therapeutic approach.

The document concludes that sex hormones are crucial for mammalian reproduction, health, and behavior, and require more research for therapeutic use.

This analysis discusses the role of genetic factors, particularly male hormones and specific gene variants, in influencing sex differences and potential susceptibility to severe COVID-19 outcomes, but notes that conclusive evidence is lacking, highlighting the need for larger studies.

The researchers reported that in mice, prolactin signaling in the skin epithelium inhibits hair follicle stem cell activation, promoting quiescence during periods of high serum prolactin like pregnancy and lactation.

This review explores the significant impacts of hormonal changes within normal physiological ranges and suggests examining low-dose effects from chemicals disrupting hormonal activity; it presents no new clinical results.
