This study evaluated the potential toxicity of oral dihydroartemisinin in SD rats, finding that female rats experienced greater toxic effects than males, particularly at higher doses, but these effects were reversible after a 4-week recovery period.

This study found that the manual hair transplantation method HFE may offer better precision and cosmetically satisfying results with minimal tissue trauma for treating androgenetic alopecia in men.

This study found that the absence of the vitamin D receptor disrupts hair follicle structure during the first catagen in mice, linked to increased expression of the hairless gene.

This study observed significant differences in the skin microbiome between hidradenitis suppurativa patients and healthy individuals, notably with decreased β-diversity and a distinct abundance of certain bacteria in affected skin.

This article reports a case of rhabdomyolysis in a patient two hours after consuming the freshwater fish Mylossoma duriventre, suggesting a possible link to Haff disease from an unidentified toxin.

This study found that mutations in exon 3 of the hr gene are strongly associated with congenital hypotrichosis in Valle del Belice sheep, suggesting a potential genetic link to the disorder.

This case report highlights that a patient developed alopecia areata following treatment with sofosbuvir and ribavirin for chronic hepatitis C.

This study found that human hair keratin bridges effectively induced nerve regeneration and demonstrated good biocompatibility and controlled degradation when used in rats with peripheral nerve defects.

This article describes a new instrument, the KD spreader, designed to help novice physicians perform follicular unit extraction hair transplantation with reduced trauma and operator fatigue, but it does not report new clinical results.

This review discusses the potential of using high-throughput and high-content screening methods for drug repositioning in rare diseases and reports no new results.

This study found that hair follicle stem cells from hidradenitis suppurativa patients showed alterations in cell cycle regulation and DNA replication, potentially linking genetic predisposition to the skin inflammation characteristic of the disease.

The authors concluded that increased expression of the HSD11B1 gene in adipose tissue correlates with obesity markers and predicts insulin resistance, but this association is independent of polycystic ovary syndrome when adiposity is controlled for.

This study evaluated the safety and effectiveness of HASHA, a new hyaluronic acid injectable, for chin augmentation in adults with chin retrusion. HASHA significantly improved chin appearance and satisfaction over 12 months compared to controls, with only mild or moderate transient adverse events.

This article reviews the pathophysiology of hidradenitis suppurativa and suggests that a complex interplay of genetic, immunological, and biomechanical factors contributes to the condition, but presents no new clinical findings.

This case report details two consanguineous patients with cerebral autosomal recessive arteriopathy, both having the same HTRA1 gene mutation, but exhibiting different clinical presentations, including one with epileptic seizures and lobar hemorrhages—previously undocumented in this condition.

This report details two patients with Hutchinson-Gilford Progeria syndrome who exhibited generalized shiny skin in infancy and had a novel mutation in the LMNA gene.

This study explores the expression and function of 11β-HSD1 in human hair follicles and its potential regulation of glucocorticoid effects on dermal papilla cells, but reports no definitive findings on 11β-HSD1's role.

This source reports that a study by Liu et al. analyzed genetic factors influencing adalimumab response in hidradenitis suppurativa, finding a specific genetic variant (SNP rs59532114) associated with an inadequate response to the treatment due to increased abscess and inflammatory nodule counts.

In this study, the researchers compared the pharmacokinetics and tissue distribution of dihydroartemisinin in nanostructured lipid carriers versus in solution, finding longer mean residence times and variable organ accumulation with the nanostructured lipid carriers.

This study explored the effects of DPP, a 15-PGDH inhibitor, on human follicle dermal papilla cells damaged by dihydrotestosterone and observed that DPP enhanced wound healing, reduced reactive oxygen species, and increased hair growth in ex vivo human hair follicle cultures.

Graft-versus-host disease is a complication where donor immune cells attack the recipient's body, often affecting the skin, liver, and gastrointestinal tract.

This abstract contains no research findings; it describes website service information and options for accessing content from JAMA Dermatology.

This study developed a composite product from decellularized human placental connective tissue matrix and placental extract, finding that the combination showed improved biochemical and mechanical properties compared to each component alone, suggesting its potential use for treating chronic and deeper wounds.

This review discusses the genetic, autoinflammatory, and keratinization factors involved in hidradenitis suppurativa and presents the concept of classifying it as an autoinflammatory keratinization disease, but reports no new clinical results.

This review discusses the roles of the hairless (HR) protein as a corepressor, particularly its impact on RORα-mediated transcriptional repression, and reports no new experimental findings.

This report describes a clinical case of a 38-year-old man diagnosed with Birt-Hogg-Dubé syndrome, confirmed by genetic testing, highlighting the presentation of multiple renal tumors and bilateral lung cysts.

This study found that hippocampus sparing whole brain radiation therapy (HS-WBRT) using multi-field intensity modulated radiation therapy prevents alopecia without compromising cognitive function compared to traditional whole brain radiation therapy.

This study found that in male rats, hesperidin co-administration ameliorated finasteride-induced testicular toxicity by reducing oxidative stress and improving antioxidant status, sperm parameters, and enzyme activity compared to finasteride treatment alone.

This study found that patient-derived HGF significantly accelerates wound healing in diabetic mice, particularly improving skin structure and flexibility, and rHGF plays a key role in boosting hair growth.

In this study, the researchers reported that a newly developed PYGL inhibitor, HTPI, enhanced hair growth in an ex-vivo culture by reducing oxidative damage in hDPCs and inhibiting glycogen degradation in hORSCs, showing potential as a treatment for hair loss comparable to minoxidil.
