In this study, women with hirsutism and amenorrhea showed lower serum estradiol and sex hormone binding globulin concentrations but higher levels of unbound testosterone compared to normal individuals.

This study identified a mutation in the KRTHB6 gene in two monilethrix families of Indian origin, linking specific genetic variations to different severities of hair defects within the families.

This study found that hHbl gene expression is localized in the cortical cells of the human hair shaft and is notably high in pilomatricoma cells transitioning to hair shaft keratinocytes.

This study found that human keratinocytes express a sodium-dependent multivitamin transporter for biotin, pantothenic acid, and lipoic acid, including a highly specific biotin transport component.

This study found that transgenic cashmere goats overexpressing thymosin beta-4 have a higher secondary to primary hair follicle ratio, suggesting potential for increased cashmere yield.

This study suggests that topically applied thyroid hormones T3 and T4 promote hair growth on human scalp tissues ex vivo, highlighting potential therapeutic use for hair loss conditions like androgenetic alopecia.

This study suggests that BTP levels in cerebrospinal fluid might help diagnose CIDP and predict therapy response but require validation in larger cohorts.

This study presents a method using liquid chromatography tandem mass spectrometry to quantify biotin in plasma and serum, and explores how high biotin intake can interfere with diagnostic immunoassays that utilize biotin-streptavidin technology, potentially leading to misdiagnosis of endocrine disorders.

This study found that in lamivudine-resistant hepatitis B patients, tenofovir significantly reduced HBV DNA levels faster and more consistently than adefovir, reaching undetectable levels in all treated patients by 44 weeks.

Early diagnosis and treatment of TPP can prevent complications.

This review discusses the free hormone hypothesis for measuring "free" testosterone and critiques its theoretical basis and clinical application, noting it lacks critical empirical testing and has inconsistent utility in assessing androgen status.

This study found a novel nonsynonymous genetic variant in the hHb1 gene of a family with monilethrix, which differs from ten previously reported pathogenic mutations.

In this study, transgenic mice with a truncated latent transforming growth factor-beta-binding protein showed reduced keratinocyte proliferation and alterations in the hair cycle due to mis-localization of transforming growth factor-beta.

This study observed that TBX3 mRNA expression levels were region-specific and correlated with pigmentation patterns in dun Mongolian horses, providing insights into the genetic mechanisms behind their distinctive Bider markings.

In this study, treatments combining betamethasone and anovulatory steroids significantly reduced testosterone production in women with hirsutism, with many reporting improved hirsutism and acne, although clinical benefit did not consistently correlate with testosterone reduction.

This review discusses multiple physiological roles of parathyroid hormone-related protein, such as cartilage mineralization and hair follicle regulation, and reports no new experimental results.

This article reports a case of hair loss and pigmentation changes in a man after using propylthiouracil alongside iodine solution for thyroid and diabetic conditions, providing clinical observations without broader conclusions.

This review covers the connection between thyroid diseases and skin conditions like alopecia, dermatitis, and vitiligo, and highlights the need for further research on the role of thyroid hormones in skin health.

This study found that high levels of parathyroid hormone-related protein expression can result in the production of shorter hair shafts, likely through effects on angiogenesis.

This study suggests that abnormal hair cycles in Hr mutant mice may be caused by HR protein overexpression, which down-regulates miR-31 and increases Tgf-β2 expression.

Thymic peptides can either promote or inhibit human hair growth.

This study found that the transcription factor HB24 plays a critical role in root hair elongation in Arabidopsis thaliana by promoting the conversion of indole-3-butyric acid to indole-3-acetic acid through regulation of IBR1 expression.

In this study, human-hair artificial tendon material showed good biocompatibility and variable degradation rates in rabbits, depending on treatment time, with minimal inflammatory reactions observed.

This study found that the truncated hHb1-DeltaN transcript in breast cancer cells is produced by a cryptic intron promoter and responds to DNA demethylation, potentially altering cancer cell adhesion.

This review explores the complex relationship between thyroid hormones and skin, discussing potential mechanisms and known interactions but reports no new clinical results, emphasizing the need for further research.

This study identified two novel point mutations in the hHb6 gene associated with monilethrix, suggesting these mutations could serve as diagnostic markers for this genetic hair disorder.

This study found that hirsutism in women is associated with elevated androgen hormone levels and increased serum TNFα, suggesting a link between androgen-driven inflammatory responses and excessive hair growth.

This study found that human TMEM2 does not function as a hyaluronidase but is involved in regulating hyaluronan metabolism.

This study found that salivary testosterone concentrations correlated better with hirsutism in women compared to serum testosterone measures, suggesting it may be an effective method for assessing bioavailable testosterone.

In this study, the authors reported that taking 20 mg or more of biotin can interfere with thyroid function tests, potentially leading to false diagnoses of conditions like Grave's disease.
