This study reports that the completeness of DNA degradation in hair during cornification varies among individuals and affects the success rates of forensic hair DNA analysis.

Mouse tail skin has different keratinization near hair follicles and scales.

This microscopy study examined the non-keratinous regions of human hair fibers, revealing detailed morphology that could help understand how external influences affect hair structure.

This study describes the structure and composition of the epidermal horny layer in elephant seals, noting that its keratinized cells are attached without a specialized fission zone, differing from the sloughing mechanism in reptiles.

This study found that hydrolyzed wheat proteins extensively penetrated both untreated and chemically treated hair, primarily occupying areas like the endocuticle and cortex.

This study characterized the mouse profilaggrin gene, finding it structurally identical to its human counterpart, and noted differences in protein-coding regions that could impact epidermal differentiation.

This study suggests that melatonin may have a radioprotective role against X-ray-induced skin damage in rats, as evidenced by milder injury markers in pretreated animals.

This review discusses the interplay between signaling/transcription factor-mediated and epigenetic mechanisms in skin development and regeneration, highlighting the need for further exploration of epigenome reorganization in these processes.

This study used electron microscopy to characterize tissues on telogen hair roots, finding that tissue quality, including nucleated and nonnucleated epithelial cells, may play a crucial role in DNA typing for forensic analysis.

This case study describes a previously unknown association of the PIBIDS complex with autoimmune thyroiditis and autoimmune hemolytic anemia in a five-year-old Indian child.

This study found that mice lacking the type 3 IP(3) receptor in their hair follicles experienced repetitive hair loss and regrowth, indicating disrupted hair-cycle regulation potentially linked to specific signaling pathways.

This review explores how cell and mouse models have contributed to understanding the mechanisms of human aging, particularly focusing on Hutchinson-Gilford Progeria Syndrome, and reports no new clinical results.

This study describes the presence of holes in hair fibers, absent in hair follicles, likely forming from daily care actions and removal of extractable substances.

This study found that mutations in the hairless gene in mice disrupt hair follicle integrity during catagen, leading to baldness due to disintegrating epithelial structures and loss of normal dermal papilla.

In this animal study, atorvastatin co-administered with trastuzumab reversed trastuzumab-induced cognitive impairment (chemo-brain) and improved its anti-cancer efficacy without causing hair loss.

This article reports electron microscope studies on the structure of hair and wool, but it does not present new clinical findings.

This review explains the mechanical composition and molecular interactions that determine hair's mechanical properties, without providing any new experimental findings.

The document explains how hair is studied in forensics to identify its source and its role in criminal investigations.

This case report describes a 78-year-old farmer with idiopathic pulmonary fibrosis who developed cutaneous Alternaria alternata infections, which improved with reduced prednisolone and itraconazole treatment, with no recurrence after two years.

In this study, researchers observed that human sebaceous glands can regenerate in a mouse model using transplanted human skin, potentially offering a tool to study sebaceous gland biology and regeneration.

The document concludes that sex hormones are crucial for mammalian reproduction, health, and behavior, and require more research for therapeutic use.

This study found that 86% of patients with follicular non-Hodgkin's lymphoma were alive and nearly two-thirds remained in complete remission eight years after initial treatment with the radioimmunotherapy drug Bexxar.

This study found that lower GPX4 mRNA levels in polymorphonuclear neutrophils of systemic lupus erythematosus patients were negatively associated with disease activity and serological markers, suggesting a diagnostic value for GPX4 mRNA.

Metformin and thiazolidinediones are similarly effective for PCOS, but metformin is often preferred due to fewer side effects.

In this study, male patients treated with 150 mCi of radioactive iodine showed no negative impact on fertility, but long-term studies with larger groups are needed to further assess hormonal effects and sperm health after this treatment.

This article describes protocols for isolating and expanding human epidermal neural crest stem cells and discusses their potential for cell-based therapies in regenerative medicine, but reports no new clinical results.

This study examined developing hair cortex with electron microscopy and found that keratin fibrils form between specific regions in hair follicles and aggregate into twisted cables.

This study investigated the role of NLRP3 inflammasomes in alopecia areata and found that outer root sheath cells may contribute to inflammation by increasing IL-1β and HMGB1 secretion when stimulated with double-stranded RNA.

This study found that C57BL/6 mice with a diet containing specific levels of vitamin A showed alterations in retinoid metabolism and increased frequency of cicatricial alopecias, suggesting dietary factors may play a role in this condition.

This review discusses hair follicle stem cells for wound healing and reports no new clinical results, noting their potential but emphasizing the need for further understanding and safety in clinical applications.
