This review discusses the potential role of vitamin D deficiency in cardiovascular and renal diseases and suggests that supplemental vitamin D could benefit cardiovascular outcomes, especially in African American and postmenopausal women; it reports no new clinical findings.

This study describes a case series of nine patients experiencing symptoms of selenium toxicity after consuming a liquid dietary supplement with an excess amount of selenium.

This study highlights conflicting evidence on the safety and efficacy of nutritional supplements for hair loss in breast cancer patients, emphasizing the need for oncologist management and further research.

A Western diet may increase acne risk, while a Mediterranean diet and certain supplements can help reduce it.

This review discusses the potential risks associated with skin, hair, and nail supplements, highlighting concerns about safety, efficacy, and lack of regulation but reports no new clinical results.

This study found that in male badgers, seasonal molting and hair growth are influenced by cycles of plasma testosterone and thyroxine, with hormones affecting the timing and progression of these processes.

This research highlights that engineered mice lacking the vitamin D receptor show multiple health issues similar to human vitamin D deficiency, underscoring the widespread impacts of the vitamin D endocrine system.

CD200 is not a reliable marker for identifying stem cells in all skin types.

This narrative review highlights the potential of naturally occurring compounds to target specific molecular pathways and overcome resistance in advanced and recurrent papillary thyroid cancer, offering new therapeutic possibilities beyond traditional treatments like surgery and lifelong hormone replacement.

This study investigated differences in gene expression in the mammary glands of SLICK and wild-type Holstein cattle, finding limited differences overall but identifying enriched pathways related to arachidonic acid metabolism and oxytocin production, which merit further exploration.

In this review, dermatological symptoms associated with various eating disorders, such as anorexia nervosa, bulimia nervosa, binge eating disorder, and pica, were examined, highlighting the potential role of dermatologists and psychiatrists in early diagnosis and interdisciplinary treatment approaches.

In this study, the safety of finasteride in rats varied depending on dosing time, while its effectiveness on prostate weight reduction remained consistent.

This study surveyed dermatologists in Greece and Italy and found significant variability and challenges in the diagnosis and treatment of alopecia areata, including limited use of severity scores and diverse treatment approaches, particularly for special site involvement and chronic cases.

This review discusses the role of oxidative stress in hair greying and suggests that understanding melanocyte susceptibility at different follicular locations may help develop therapies for preventing and reversing the process; it reports no new experimental results.

Bone-marrow and epidermal stem cells help heal wounds differently, with bone-marrow cells aiding in blood vessel formation and epidermal cells in hair growth.

This study proposes a two-step method that may enhance the generation of stem-like epidermal cells with superior proliferation and differentiation potential for skin regeneration.

This review examines the direct-to-consumer genetic testing market, highlighting the available tests, regulatory issues, and calls for increased oversight, and reports no new results.

This study found that C8/144B antibody exclusively binds to the hair follicle bulge and not the epidermal stratum basale, with cytokeratin 19 serving as a key marker of certain basal keratinocytes that decrease with age.

This thesis presents research conducted in partial fulfillment of a Master's degree in Software Systems Engineering but does not report new empirical findings.

In this study, fenugreek seed extract showed significant androgenic and spermatogenic effects in male rats, likely through inhibiting testosterone metabolism, without impacting cardiovascular health.

This review discusses the diversification of tea products and their associated health benefits, highlighting the economic challenges faced by tea-producing countries and the global marketing strategies of the tea industry, but reports no new experimental findings.

This study aims to assess how daily life factors affect sleep patterns and describe individual sleep changes across the year, with results to be published in future research.

This study found that the circadian clock regulates the activation state of murine epidermal stem cells, affecting tissue homeostasis and susceptibility to tumorigenesis when disrupted.

This study found that polycomb-group-mediated repression plays a key role in regulating hair follicle stem cell states and lineage progression by distinct mechanisms in adult mouse skin.

This protocol describes using two-photon laser-scanning microscopy to study hair regeneration in live mice, offering detailed imaging capabilities for observing hair follicle stem cell behavior and manipulating cellular populations.

This study found that four days of simulated night shift work in healthy adults reduced insulin sensitivity, suggesting a potential increased risk of type 2 diabetes.

This study found that temperature affects the influence of daylength on prolactin secretion and hair growth in dairy goats, without significant involvement of melatonin.

Continuous light exposure in rats leads to PCOS-like symptoms and suggests sleep habits might affect the disorder's development.

This review examines the recent progress in using bioactive molecules for skin regenerative medicine and reports no new clinical results; the authors suggest this method could become a promising strategy for in situ skin regeneration.

This study found that keratinocyte stem/progenitor cell-conditioned medium significantly enhanced hair growth in mice and increased the proliferation of human hair follicle cells.
