This report describes a unique case of hereditary vitamin D-resistant rickets (HVDRR) in a dog, caused by a VDR gene mutation resulting in severe hypocalcemia and bone issues, which presented with symptoms similar to those observed in humans.

β-estradiol slows hair growth in mice.

In this study, researchers developed a new classification system for anterior hairline types among Asian males without androgenetic alopecia, finding MM, RM, and ML to be the most common types.

This study found that early-onset male androgenetic alopecia is associated with abnormal lipid metabolism and lower levels of certain serum markers, which may serve as risk factors or protective factors for the condition.

This case report describes an unusual nail tumor termed "onycholemmal horn" in a 77-year-old woman, highlighting its distinct histopathological features and the importance of excisional biopsy for accurate diagnosis.

Panthenol is more effective than hydrolyzed protein at improving hair roughness and reducing breakage.

This study found that using standardized photography for patients with hair loss improves clinical documentation, which in turn can enhance patient care and treatment outcomes.

Viral reactivation is rare at the time of DRESS diagnosis in the U.S.

This study found that microwave-assisted Opuntia humifusa extract improved antioxidant and anti-inflammatory properties to counteract particulate matter's harmful effects on HaCaT keratinocytes.

This study found that women with polycystic ovary syndrome have more pronounced metabolic alterations and higher androgen levels compared to women with eumenorrheic hyperandrogenism, suggesting EuHyperA may be a milder form of PCOS.

In this study, researchers developed a mathematical model of outer hair cell hair bundles that replicates experimental responses to mechanical stimuli, providing insights into the stimulus-dependent adaptation mechanisms and the functional significance of their three-row stereocilia configuration in mammalian hearing.

This article reviews the essential role of vitamin D in bone health and its various clinical applications but reports no new clinical findings.

This article discusses the importance of routine karyotyping in patients with congenital adrenal hyperplasia, as it may reveal the presence of Turner syndrome and recommends early diagnosis and treatment; it reports no new clinical results.

In this case study, a 62-year-old woman with ovarian hyperthecosis experienced normalization of elevated testosterone levels and improvement in hirsutism and hair loss following bilateral salpingo-oophorectomy.

This study highlights a rare case of ovarian hyperthecosis in a 58-year-old postmenopausal woman, presenting with polycythemia and severe hyperandrogenism symptoms, with resolution of symptoms following laparoscopic bilateral oophorectomy.

This article provides guidelines for molecular genetic testing of congenital adrenal hyperplasia due to 21-hydroxylase deficiency, focusing on quality requirements, methodologies, and variant classification; it reports no new clinical results.

This study found that 1,25 dihydroxyvitamin D3 significantly increased the expression and activity of vasculoprotective natriuretic peptide receptor-A in cultured inner medullary collecting duct cells, suggesting a potential mechanistic role in cardiovascular and renal benefits.

This study found that oxybenzone is very stable under light exposure, contradicting previous findings of its oxidation to semiquinone after solar irradiation.

This article reports two cases where ovarian hyperthecosis caused hyperandrogenism in postmenopausal women, confirmed by imaging and resolved after bilateral oophorectomy.

This review discusses the role of vitamin D and its receptor in maintaining skin and hair follicle health, but it reports no new clinical findings.

In this study, Tmem30b was identified as a key regulator of outer hair cell structure in mice, and its modulation may offer a therapeutic approach for certain types of hearing loss.

In this review, the authors noted that while baricitinib, a treatment for refractory rheumatoid arthritis and severe alopecia areata, shows promising efficacy, it may pose risks of serious infections and malignancy due to immune downregulation.

This study found that baricitinib, a selective Janus kinase inhibitor, led to significantly improved scalp coverage in alopecia areata patients over 36 weeks compared to placebo, though adverse effects like acne and urinary tract infections were reported.

This study suggests that 1,25-dihydroxyvitamin D(3) and fibroblast growth factor 23 form a crucial axis in regulating phosphate balance, akin to its role in calcium regulation, and explores novel VDR interactions including with curcumin.

This study reported that men with more significant hair loss experience greater negative psychosocial effects, particularly noticeable in younger age groups.

This article reviews the role and clinical applications of 1,25-dihydroxyvitamin D3 and parathyroid hormone-related peptide in dermatology, with a focus on psoriasis treatment, and reports no new experimental findings.

This study found that in SAMP8 mice, phenotypic changes in outer hair cells or the stria vascularis, possibly due to oxidative deficiencies, may predict variability in age-related hearing loss before outer hair cell loss occurs.

This study found that minoxidil increases the expression of a reporter gene linked to hair growth in cultured hair follicles from transgenic mice, suggesting a potential model for studying hair biology.

This study found that vitamin D was positively associated with serum ferritin levels in Korean women without metabolic syndrome, but this association was not observed in those with metabolic syndrome.

This study observed that knocking out the 1α-hydroxylase gene in mice resulted in rickets and growth retardation, demonstrating the enzyme's crucial role in vitamin D function in animals.
