This study found that men with androgenetic alopecia had significantly lower serum vitamin D levels compared to controls and the deficiency strongly correlated with the severity of the condition.

This scoping review suggests that physiological differences in skin structure may affect how individuals with different skin tones respond to pressure ulcer development, emphasizing the need for targeted prevention strategies.

This study found that melatonin may enhance hair follicle stem cell viability by downregulating the nuclear receptor RORA, which otherwise inhibits cell proliferation and promotes apoptosis.

In this study, researchers observed that telogen hair was more prevalent than anagen hair in both male and female agoutis over a one-year period in Teresina-PI, regardless of dry or rainy seasons, with no significant differences in dermal follicular volume between the sexes.

This study developed and tested two methods to accurately quantify hair growth rates in polar, black, and grizzly bears using dye application and isotopically labelled amino acids, revealing growth rate variations by individual and season.

This study examined Prunus mira populations in the Qinghai-Tibetan Plateau and found high genetic diversity and substantial phylogeographic structure, suggesting geographic isolation limits gene flow; the researchers propose conservation strategies to preserve genetic resources.

This study found that patients with alopecia, particularly alopecia areata and female pattern hair loss, often have vitamin D deficiency, suggesting that screening for vitamin D could benefit these patients.

This study suggests moving away from using rigid racial categorizations and outdated typologies in favor of analyzing detailed trait patterns, providing a foundation for future research on human variation and hair traits in relation to population affinity.

This study found that supplementing pregnant Hanshan white cashmere goats' diets with selenium yeast led to higher birth weights, improved cashmere quality and yield, and enhanced hair follicle development in their offspring, possibly through increased antioxidant capacity.

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 found that short-day photoperiod treatment in Shanbei white cashmere goats enhanced cashmere growth, increased secondary follicle density, and altered hormone levels and gene expression related to hair follicle development.

In this study, higher Fitzpatrick skin type, non-summer season, and non-White race were associated with vitamin D insufficiency in US children with alopecia areata.

This study found no significant difference in serum ferritin, zinc, and 25-hydroxy vitamin D levels between women with chronic telogen effluvium and healthy controls, although suboptimal levels were common in both groups.

This abstract only contains a stylized text design and provides no research findings or clinical results.

This article reviews the case of a patient diagnosed with basal cell nevus syndrome and reports no new research findings.

This study found that lower urinary tract symptoms were linked to reduced functional ability in older adults, with distinct associations for nocturia in men and frequency, urgency, and overactive bladder in women.

This study found that family caregivers reported significantly longer sleep onset latency compared to carefully matched non-caregiving controls, with depressive symptoms predicting poorer sleep quality among caregivers.

This article reviews how stem cell exhaustion contributes to aging, emphasizing the balance between proliferation and quiescence as crucial for long-term stem cell maintenance, but it reports no new results.

This case study describes a 31-year-old man with myotonia and a history of hypertrophic cardiomyopathy and androgenic alopecia, who presented with arm and leg weakness.

In this study, GERD symptoms were found to be significantly related to acid exposure time and the intensity of excessive daytime sleepiness, which depends on circulating ghrelin levels.

This clinical case report describes a 72-year-old man who experienced significant weight loss and frequent loose stools over eight months, presenting with fatigue.

This study identified hemoglobin level as the strongest biological predictor of fatigue in systemic lupus erythematosus patients, highlighting its association with disease activity and systemic inflammation.

This letter humorously reflects on aging and disputes the notion of "Geezer syndrome" linked to the Great Depression, emphasizing resilience and growth in knowledge over time.

This study reports that even minimal improvements in SLE-related fatigue and skin symptoms are meaningful to patients, supporting the content validity of the FACIT-Fatigue scale for measuring these effects.

This article examines the Ayurvedic perspective on the aging process, detailing how physical, emotional, and metabolic changes occur naturally over time, affecting various body systems, and highlights the role of Vayu dosha during the final stage of life, Vriddhavastha.

This meta-analysis found that rheumatoid arthritis patients experience poorer sleep quality compared to healthy controls, including reduced total sleep time and efficiency, longer sleep latency, and increased wakefulness after sleep onset.

This study highlights the increasing prevalence of premature graying (Premature Canities) in young adults, linking it to factors such as oxidative stress, genetic predisposition, and environmental pollution, with notable concern in tropical and developing countries.

This study found that depression, anxiety, and sleep disturbance were associated with male lower urinary tract symptoms, but these factors did not predict improvement after evaluation and treatment over time.

This article argues that polysomnographic studies recommended for factitious leg ulcers in patients may be based on faulty assumptions about causality related to unusual sleep disorders.

This study found that individuals with homozygous loss-of-function mutations in PLAAT3 experience a novel type of partial lipodystrophy linked to defects in white adipose tissue differentiation and function.
