This study identified the presence of the enzyme 1 alpha-hydroxylase in various extrarenal tissues, suggesting its potential role in modulating vitamin D function in peripheral tissues.

This study found that tribuloside, a flavonoid from Tribulus terrestris L., enhances melanin production in human melanocytes, zebrafish, and human skin samples without causing toxicity, potentially through inhibiting PDE to increase cAMP levels and promote the melanin biosynthesis pathway.

In this case study, hypertrichosis in a patient with hemophilia and hepatitis C may have been induced by IFN-alpha treatment, despite the drug usually causing hair loss.

This study found widespread localization of parathyroid hormone-related protein in normal and cancerous canine tissues, suggesting a potential physiological role as a paracrine or autocrine factor.

This study found that intrathyroidal injection of autologous platelet-rich plasma improved thyroid function and symptoms in hypothyroidism patients, without adverse events over one year.

In this study, phenylthiocarbamide intake was associated with hair graying in rats, while switching to tap water led some rats to regain their original fur color, suggesting dietary factors influence pigmentation.

This study found that increased intracellular expression of thymosin β4 is necessary and sufficient to induce PAI-1 gene expression in endothelial cells, potentially mediated through Ku80 as a novel receptor.

This article reviews the need for multicenter clinical trials to establish reference data for ultrasound screening protocols for Down syndrome and reports no new findings.

This article discusses solitary hirsutism, emphasizing that treatment is mostly cosmetic unless contraception is also desired, and reports no new clinical results.

This study reports that variation in the ovine TCHH gene may influence wool fibre curvature, with specific gene variants affecting the mean fibre curvature in sheep.

This thesis reveals that tenuazonic acid inhibits plant plasma membrane H+-ATPase, suggesting its potential as a herbicide due to its impact on root elongation and cell viability in Arabidopsis thaliana.

This case report describes a post-menopausal woman with severe hirsutism whose high testosterone levels decreased after gonadotropin suppression, indicating residual hormone-producing tissue responsive to gonadotropins.

In this study, TASP0382088 showed potent selective inhibition of the ALK5 receptor, significantly reducing Smad2 phosphorylation in mouse skin following topical application.

In this study, researchers tested a tea leaf ethanol extract (Camellia sinensis) hair tonic and found it increased average hair growth compared to positive and negative controls over 28 days, but exhibited some instability and inhomogeneity after accelerated testing.

This article reviews the structure and regulation of the ITGB6 gene and discusses its role in integrin αvβ6 expression, with no new experimental results reported.

This study found that supplementing Liaoning cashmere goats with HMBi increased cashmere length while decreasing its diameter, attributed to changes in Met-related metabolites and elevated expression of genes related to the Met cycle and cell differentiation pathways such as Wnt and MAPK.

This case report describes a 4-year-old dog successfully managed for primary hypothyroidism and concurrent Babesia gibsoni infection, treated with thyroxine, Diminazine aceturate, antibiotics, and supportive therapies, resulting in clinical improvement and negative blood smear for Babesia by day 30.

This narrative review discusses the hormonal control of hair growth, particularly focusing on dihydrotestosterone and its role in the pilosebaceous unit and androgen-related hair conditions, and does not report new findings.

In this study, reversible ageusia in a patient was strongly suggested to be caused by losartan, with potential implications for angiotensin receptor involvement in taste disturbance.

This article reports on three new cases of Birt–Hogg–Dubé Syndrome and emphasizes the role of genetic analysis in its diagnosis due to clinical challenges.

This study demonstrated that tocotrienol supplementation increased hair number in individuals with hair loss compared to a placebo, likely due to its antioxidant effects.

This study found that untreated hirsute patients have lower expression of type 2 17β-HSD mRNA in scalp hairs, indicating potential disturbances in androgen metabolism, compared to treated hirsute patients.

In this study, 35.4% of telogen effluvium patients showed ferritin deficiency and 34.2% had vitamin D deficiency, suggesting these should be included in TE screening; TSH testing should be individualized.

In this case report, a 70-year-old woman with a history of autoimmune hypothyroidism experienced alternating hypothyroidism and hyperthyroidism over a decade, highlighting the potential role of thyrotropin receptor autoantibodies in these fluctuations.

This study found that treatment with PTH-CBD stimulated hair growth in mice with alopecia areata, with increased levels of beta catenin indicating activation of the Wnt pathway.

Traditional Persian medicine helped a woman with resistant hyperthyroidism improve and stabilize her condition.

This study highlights two newly discovered metabolic disorders of biotin, showing distinct skin and hair symptoms and severe complications like acidosis and ketosis.
