This narrative review highlights that endurance, skill-oriented athletes, and physique-oriented competitors such as bodybuilders face accelerated degradation of fillers and botulinum neurotoxin due to elevated basal metabolic rates and other factors, and raised concerns about psychological conditions like body dysmorphic disorder in these populations.

This study explored the experiences of adolescents with alopecia and their parents, highlighting the emotional distress caused by the condition and the inadequate response of healthcare professionals to their needs.

This study found a statistically significant increase in glycosylated hemoglobins among patients with adult-acquired panhypopituitarism undergoing long-term GH replacement therapy, with two developing diabetes requiring treatment.

This review discusses recent research on the relationship between gut microflora and depression, highlighting the potential for new insights into the pathogenesis and treatment of major depressive disorder.

This study observed that while dexamethasone-cyclophosphamide pulse therapy is relatively free from hypertension and diabetes compared to conventional steroids in pemphigus patients, it frequently causes generalized weakness and flushing.

This review covers recent findings on stem cell plasticity under normal and cancerous conditions but presents no new experimental results, highlighting implications for regenerative medicine and cancer treatments.

This review explores the hormonal regulation of hair growth and changes with season, age, and sexual development, and calls for improved treatments for hair disorders.

This study found that human skin expresses proenkephalin, whose expression is upregulated by environmental stress and varies in pathological conditions, increasing in psoriasis and decreasing in melanocytic tumors.

This study reports that X chromosomes often show greater differentiation between human populations than autosomes, likely due to a mix of demography and selection pressures.

This study reports that eccrine sweat glands in mice predominantly develop on the footpads, offering a reference for skin research involving genetically engineered mice.

In this review, the role of DHT in male-type obesity and metabolic diseases is discussed, with increased levels potentially exacerbating cardiovascular disease risk; the paper reports no new results.

This study reports that finasteride treatment in men with androgenetic alopecia appears to restore caspase and XIAP expression in hair follicles to levels similar to those in individuals without the condition.

This study found that neural crest-derived hair follicle cells in mice can differentiate into osteoblast-like cells, suggesting a potential application for bone regenerative therapies.

Pigs are a good model for studying human hair growth and disorders.

This study found that women aged 21-26 with PCOS showed significant differences in biochemical and hormonal profiles, such as blood sugar and hormone levels, compared to healthy individuals, suggesting an increased incidence of PCOS in this age group.

This study utilized a mouse model of traumatic brain injury to reveal that acute neurotrauma triggers widespread lipid metabolism reprogramming and storage lipid accumulation in microglial and monocyte populations, leading to lysosomal dysfunction, inhibited autophagy, and exacerbated inflammation through a pathological feedback loop.

In this study, researchers in Baghdad, Iraq found that men with hair loss had higher body fat mass and haematocrit values, and lower blood pressure compared to men without hair loss, suggesting potential links between metabolic and hematologic changes and baldness.

This study found that dermal papilla cell-conditioned medium can protect against UV-induced skin aging in a mouse model by modulating ferroptosis pathways, highlighting its potential for treating oxidative stress-related skin conditions.

In this study, researchers found that disrupting the PRL gene in mice led to earlier hair molting, especially in females, suggesting that PRL inhibits murine hair cycle events.

This study found that the dermal papilla of the hair follicle regulates stem cell quiescence and regeneration by modulating Shh and Wnt signaling pathways, highlighting the importance of signaling cross talk in regeneration.

This study found that disrupting the PRL gene in mice alters the timing of hair cycling events, causing earlier molts and changes in hair characteristics, particularly affecting female mice more significantly.

This study found that Na2SiO3 accelerated hair regrowth in mice, indicating potential for treating alopecia, though it did not significantly alter enzyme activity compared to distilled water.

This study found that ocu-miR-205 affects signaling pathways, promoting the apoptosis of dermal papilla cells and influencing hair follicle density in Rex rabbits.

This study found that ocu-miR-205 promotes apoptosis in dermal papilla cells, alters hair follicle signaling pathways, and affects hair density in Rex rabbits.

This study found that ocu-miR-205 promotes the apoptosis of dermal papilla cells and the transformation of hair follicles from growth to regression and resting phases in Rex rabbits.

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 review discusses the impact, pathophysiology, and health risks of obesity and the metabolic syndrome in polycystic ovarian syndrome, emphasizing the potential life-saving benefits of recognition and treatment, but it reports no new results.

This study found that manipulating prolactin levels in New Zealand Wiltshire sheep induces wool follicle growth cycles, revealing gene expression changes that suggest roles for specific genes in follicle function.

This systematic review found that probiotic supplementation improved sleep quality, reduced depressive symptoms, and enhanced aspects of quality of life in women with PCOS, though the findings are limited by a small number of studies and variable methods.

This research identified unique gut microbiota patterns in alopecia areata patients, with potential as diagnostic biomarkers and suggesting avenues for microbiota-focused therapies.
