This study analyzed the Chinese version of the Symptom Checklist-90 and suggested revising 18 items to improve its quality and relevance.

This study found that enzymatic conversion of Arg-51 in S100A3 protein to citrulline promotes homotetramer assembly, potentially increasing Ca²⁺ binding required for hair cuticular barrier formation.

This study revealed that human keratin-associated protein genes are expressed in specific patterns in hair fiber regions and vary in size, with some variations distinct across different populations.

Recent hair loss research shows some progress, especially in understanding male pattern baldness, but effective treatments for many types of hair loss are still lacking.

In this report, the author shares experiences from a six-month curricular internship, highlighting activities such as arterial pressure monitoring in a community pharmacy and addressing off-label rituximab use at a hospital, alongside discussions of hair loss treatments and nutritional supplementation for dysphagia in the elderly.

This study found that examining the microscopic and ultramicroscopic structures of donkey and horse hair can help differentiate between the species based on distinct differences in hair cuticle and brain substance patterns.

This research observed that, in domestic cats like Maine Coon and Rex breeds, a "piebald" coat color pattern is likely influenced by the Silver locus, although the specific mutations involved are yet to be published.

This study found distinct localization patterns of S100 family proteins in hair follicles, suggesting their differential roles in normal hair follicle physiology.

This article reviews common hair growth abnormalities in children, emphasizing the importance of distinguishing normal development from potential signs of metabolic disorders and indicates no new clinical results.

This study establishes a catalog of human type I hair keratins and identifies their specific roles and expression patterns during hair differentiation and growth in scalp follicles.

This study identified novel compound heterozygous mutations in the DSG4 gene in a Japanese patient with congenital hypotrichosis, suggesting overlap between localized autosomal recessive hypotrichosis and monilethrix.

This study reports the cloning and sequencing of two type II hair-specific keratin genes, ghHb1 and ghHb6, located on chromosome 12q13, which are expressed during hair growth.

This study found that excessive heat caused the most significant structural changes in hair from Caucasian and Afro samples, especially when combined with other treatments like bleaching and straightening.

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 discusses the clinical presentations of alopecia areata, introduces guidelines for treatment studies, and explores potential changes in cutaneous innervation, but reports no new clinical results.

This study investigated the hair structure of wild pigs in the Balıkesir region using stereomicroscopy and scanning electron microscopy, finding distinct bifurcation patterns, but concluded that pig bristles used in brushes likely wouldn't retain these features, complicating species identification.

This study found that using a microscope can effectively distinguish between human and animal hair based on microscopic characteristics, making it a critical tool in forensic investigations.

This case study found that a 7-year-old girl's crystalline cataract had sulfur-containing amino acids likely cystine, and was associated with abnormal hair conditions.

This study visualized mitochondrial metabolism in cultured bovine hair follicles and plucked human hairs, finding that ROS and mitochondrial polarization correlate in specific hair follicle regions, particularly near keratin deposition sites.

This article discusses recent findings on piedra infections in hair and their keratinolytic activities, but reports no new clinical results.

In this study, researchers explored how hair follicle orientation is affected in the rosette fancy mouse and found that a mutation in the PCP gene Fzd6 caused reversed hair orientations in the posterior region, leading to the formation of unique whorls.

This article reports a case of a 19-month-old boy with scalp erythematous papules and hair loss, showing no improvement with initial treatment.

The authors discuss that hair loss affecting the occipital scalp is understudied and may be caused by factors like movement irritation and clothing occlusion; this lack of data can lead to missed diagnoses and inadequate treatment.

This study suggests that seasonal rhythm genes in cashmere goat skin are differentially expressed with changing daylight, potentially affecting hormone transformation and light sensitivity.

This article provides a diagnostic guide for clinicians to differentiate between various hair shaft disorders by using a structured question-by-question approach but does not report new clinical findings.

This paper reviews plica polonica, a rare hair disorder linked historically to poor hygiene and now to severe self-neglect or medical conditions, and outlines various treatment and preventive strategies but reports no new findings.

This study found that Prss53-mutated rabbits exhibited curved hair and skeletal dyskinesia, suggesting a link between Prss53 loss and these traits, potentially involving disrupted calcium metabolism.

The document concludes that individualized treatments for hair issues are effective, certain hair changes can indicate neurocutaneous diseases, specific lotions improve skin health, laser hair removal works but needs more study on long-term effects, men's cosmetics are diverse, peeling is effective but can have side effects, and facial pigmentation is often due to overactive skin cells.

This study found that medical students have limited awareness and understanding of plastic surgery beyond cosmetic procedures, prompting the development of new educational modules to enhance their knowledge.

Mammalian hair scales change from smooth to wavy due to friction.
