This case series describes three siblings with hereditary vitamin D-resistant rickets, highlighting variations in their clinical presentations.

Some people have a genetic variation that makes them less effective at breaking down drugs.

This study investigates the complex impact of bariatric surgery on skin disorders, reporting improvements in conditions like acanthosis nigricans and psoriasis, while new issues such as xeroderma and alopecia may also emerge postoperatively.

This study observed that patients with alopecia areata had significantly lower serum 25-hydroxyvitamin D levels than healthy controls, with a trend toward even lower levels in more severe cases.

This article reviews the biology of epithelial stem cells and their role in tissue self-renewal, maintenance, and regeneration, and it highlights the clinical implications of understanding their signaling pathways, but it presents no new clinical findings.

Finasteride helps regrow hair and shrink prostate by reducing DHT, with some sexual side effects.

In this study, oral administration of Lactococcus lactis strain H61 to senescence-accelerated mice was linked to reduced bone density loss, less skin ulcer incidence, and reduced hair loss, along with altered immune responses.

This study found that male germ-free rats fed semisynthetic diets do not grow as rapidly as their conventional counterparts and require dietary biotin for normal metabolism and folic acid biosynthesis.

This review found little evidence supporting zinc as a first-line treatment for dermatological conditions, except in cases of systemic zinc deficiency, and suggests further research is needed.

This review discusses the use of zinc in treating dermatological conditions and concludes that, aside from systemic zinc deficiency, its efficacy as a primary treatment is unproven, though it may be useful as a supplementary therapy.

This study found that a bacterial endophyte from Zea nicaraguensis effectively targets and colonizes plant root hair cells, promoting growth and solubilizing insoluble phosphorus for nutrient uptake.

This study created a humanized mouse model of hereditary vitamin D-resistant rickets that lacks alopecia, indicating the mutant receptor's potential to explore the syndrome's characteristics beyond vitamin D binding.

This article discusses the popularity and issues of fad diet books like "The Beverly Hills Diet," and reports no new research findings on effective or safe weight loss methods.

This article offers strategies for managing acne effectively and safely, emphasizing treatment optimization, patient tailoring, and addressing antimicrobial resistance, but reports no new clinical results.

This study presents a detailed overview of lymphatic vessel development and highlights the role of abnormal lymphangiogenesis in various diseases, suggesting that targeting lymphangiogenic factors may improve treatment strategies.

This review discusses the role of biotin in metabolism and the consequences of its deficiency, reporting no new clinical results.

In this study conducted on Iraqi individuals with celiac disease not on a gluten-free diet, researchers observed elevated serum urea and creatinine levels, which may indicate an increased risk of renal dysfunction, alongside decreased magnesium, zinc, and vitamin C compared to healthy controls.

This study found that Iraqi women with PCOS who carry the reference wild type alleles of OCT1 had a significant hormonal and metabolic response to metformin, unlike those with mutant alleles.

In this study, Brazilian patients with inflammatory bowel diseases had a higher prevalence of skin lesions, including alopecia, xerosis, striae, and acne, compared to healthy controls.

This research outlines how retinoids, compounds based on vitamin A, activate nuclear receptors to influence cellular processes such as differentiation and carcinogenesis, with benefits like anti-inflammatory properties but requiring careful management of dose-dependent side effects.

This article discusses the challenges and methodologies in veterinary clinical trials, emphasizing the need for robust protocols and statistical rigor, without presenting new experimental results.

In this study, researchers assessed vitamin D3 levels in adolescents, finding a suboptimal average of 22.00 ng/ml, and demonstrated that supplementing with 1000 IU/day of vitamin D3 significantly raised levels and improved physical and mental potential over two months.

In this study, the Mason gastric bypass resulted in significant weight loss, with most patients losing over 25% of their total weight and maintaining it, despite some risk of complications.
