This study reports a case of an ovarian steroid cell tumor with malignant potential, presenting unusually with osteopenia and low weight instead of the expected virilizing symptoms.

In this study, 17β-estradiol increased VEGF production in differentiated THP-1 cells, while dihydrotestosterone counteracted this effect by modulating adenylate cyclase activity.

This study found that modifying biphasic calcium phosphate/poly(methyl methacrylate) bone cement with human hair keratin improves its hydrophilicity, mechanical properties, and supports bone repair in rats, indicating potential for orthopedic applications.

In this study, researchers found that mitochondrial complex I plays a crucial role in regulating innate immunity and bone remodeling, with Ndufs4 deletion causing systemic inflammation and osteopetrosis through various metabolic shifts and cellular mechanisms.

This study found that applying BMP2 stimulated limited regeneration of the amputated P2 bone in mice, but only when applied during a specific "regeneration window" after injury.

This study found that encapsulating dermal papilla spheroids in alginate hydrogel with extracellular matrix proteins increased alkaline phosphatase activity, suggesting an enhanced manipulation of dermal papilla activity.

This study found that women with hyperandrogenic amenorrhea do not show reduced bone mineral density compared to controls, indicating they may be protected from osteopenia.

This study found that perifollicular mineralization in old toy poodle bitches was associated with high mineralization levels in other tissues.

This study identifies cartilage oligomeric matrix protein (COMP) as a key extracellular matrix component in human hair follicle cycling, potentially regulated by TGFβ signaling, and suggests its importance in normal hair follicle biology.

This study found that iodine deficiency, iodine excess, or the presence of antithyroid substances affected growth and behavior in Wistar rats, leading to various symptoms such as lethargy and alopecia.

This study suggests that Ecklonia cava, particularly its component dioxinodehydroeckol, may promote hair growth by enhancing dermal papilla and outer root sheath cell activity in culture and mice models.

This research developed a zinc-doped nanocomposite using biodegradable materials, observing effective bone targeting and regeneration capabilities in vivo, with no observed cytotoxicity in the MG63 cell line, potentially due to blocking Farnesyl Diphosphate Synthetase to inhibit osteoclastic activity and promote osteogenesis.

This article reviews various updates in dermatology, including drug safety alerts and treatment options, and reports no new clinical results.

In this study, estetrol (E4) treatment was associated with increased hair growth in ex vivo human hair follicles, suggesting its potential as a treatment for hair loss disorders.

This study associated ivory-colored areas observed through trichoscopy with steroid deposits in the dermis among patients with steroid-induced atrophy on the scalp.

This paper considers fibrodysplasia ossificans progressiva as a segmental progeroid syndrome, which may help uncover mechanisms of normal aging and suggest targets for new treatments.

This case report discusses a young woman who developed bilateral osteonecrosis of the femoral head after corticosteroid treatment for alopecia areata, underscoring the risk of this complication in patients undergoing such therapy.

This study found that copper levels varied significantly by gender, while young infants had higher levels of copper, zinc, calcium, magnesium, and iron compared to older age groups.

This study suggests that human trichohyalin may function as a flexible rod linking keratin intermediate filaments and as a scaffold protein in hair follicle and epidermis cell envelopes.

This theoretical research project proposes the Carnivore Follicular Integrity Framework, suggesting that animal-based diets may support hair follicle stability through various evolutionary and mechanistic pathways.

This study found that experimentally induced calcification in rat skin led to rapid and localized mineralization in hair follicles, progressing to more extensive calcification with prior hypercalcemic treatment.

This study found that boehmite accelerates hair regrowth by promoting human dermal papilla cell proliferation and enhancing signaling pathways involved in the hair follicle cycle.

This study found that the keratin matrix in mammalian hard α-keratins is crucial for maintaining stiffness in water by controlling intermediate filament hydration.

In this study, hair shafts from trichothiodystrophy patients with ERCC2 mutations revealed abnormal cuticle structures and protein imbalances compared to normal hair shafts.

This study found that incorporating cell-adhesive ligands into 3D peptide hydrogels supports the survival and osteogenic differentiation of human amniotic mesenchymal stem cells.

This study suggests that low phosphorus and ethylene may influence root hair density through separate pathways, with ethylene manipulation affecting root hair growth in Arabidopsis thaliana.

This study observed that increasing the γ-kerateine content in meta-kerateine materials led to reduced elasticity, solidity, and hydrolytic stability, and decreased hepatocyte attachment support.
