This case report describes acute liver injury in a 5-year-old Caucasian girl after ingesting the Chinese herbal product Shou-Wu-Pian, suggesting a potential link between this unregulated herbal remedy and hepatotoxicity.

This study found that the fungus Microsporum gypseum enzymatically degrades keratin in human hair, with the sequence of degradation reflecting the keratinization and cystine content of individual hair components in vitro.

This study reports that a novel frameshift mutation in the HTRA1 gene in a CARASIL pedigree led to reduced HTRA1 protein and increased TGF-β1 expression, potentially causing severe CARASIL and peripheral small arterial disease.

In this animal study, pigs on a biotin-deficient diet showed significant hair loss, weak and brittle claws, and skin lesions after 8–10 weeks, with tissue necrosis observed microscopically after 15 weeks.

In this study using ex vivo porcine ear skin, researchers found that standard nail varnish applied gently creates effective follicular closures, preventing penetration of certain substances like fluorescein sodium salt and caffeine into hair follicles, whereas solvent-free varnish and rapid application techniques were less effective.

This study found that trichohyalin is expressed in cancerous tongue epithelial cells, while plectin-1 expression may indicate malignancy.

Unknown factors significantly affect hair growth in skin grafts.

This case study reported that a 13-year-old cat with paraneoplastic alopecia due to an intraabdominal apocrine adenocarcinoma exhibited ventrally distributed alopecia and shiny skin, with necropsy showing telogenisation and miniaturisation of the hair follicles.

In this case report, researchers document the first known instance of a dog developing both uveodermatological syndrome and alopecia areata concurrently, similar to occurrences in human patients, and provide a detailed overview of the clinical presentation, diagnosis, treatment, and follow-up.

This review discusses different types of hair loss, their potential causes, and advances in treatments, and reports no new clinical findings.

This study observed that PCAT1 and HOTAIR gene expressions were significantly lower in individuals with androgenic alopecia compared to healthy controls, suggesting their potential involvement in the condition's pathogenesis.

This study found that Katsuwonus pelamis heart hydrolysates promoted hair growth in human dermal papilla cells, a 3D hair follicle organoid model, and C57BL/6 mice, suggesting its potential as a bioactive hair growth ingredient.

This study found that androgen inactivation pathways in scalp sebaceous glands change with age, specifically noting that AKR1C expression, including AKR1C4 previously thought liver-specific, declines with age and is sex dependent, which could impact hair follicle health during aging.

This study found that overexpressing the gene OsPRX83 in rice plants enhanced osmotic and oxidative stress tolerance compared to wild-type and mutant rice, showing potential for engineering drought-resistant rice varieties through ABA-dependent pathways and ROS scavenging.

This study identified a novel genetic mutation, c.429delC in the hairless gene, associated with atrichia with papular lesions in two Pakistani families.

This study found that topically applied nano-Zinc oxide accumulated in hair follicles and induced apoptosis in hair follicle stem cells, indicating a potential risk to skin homeostasis.

This study found that deoxycorticosterone-derived neurosteroids modulate GABA A receptor function and may influence stress-induced changes in seizure susceptibility by elevating seizure thresholds in animal models.

In this study, researchers examined a new propylene glycol-free 5% minoxidil lotion for 6 months among individuals with androgenic alopecia and found it demonstrated good clinical efficacy, with 74% showing a positive response, and very high cosmetic acceptability and tolerability, comparable to traditional formulations.

This study found that the hairless gene product (Hr) suppresses VDR-mediated gene activation by directly interacting with the vitamin D receptor, potentially affecting hair follicle function.

This review discusses the role of the EGF receptor/ligand system in skin homeostasis and its implications for keratinocyte stem cells and reports no new clinical results.

Overexpressing the epigen gene in mice leads to enlarged sebaceous glands and greasy fur.

In this study, Waved-5 mice with reduced EGFR signaling showed nearly normal skin and hair follicle function but experienced a transient reduction in subcutaneous fat.

This review highlights the potential of microneedles for immunotherapy, emphasizing their ability to enhance immune responses and reduce side effects through precise and stimuli-responsive delivery, especially in tumor treatment, while also noting the limitations and areas for improvement in current systems.

This review discusses transdermal drug delivery using hydrogel-forming microneedles and highlights their potential and challenges for clinical application, but it reports no new clinical findings.

In this study, isatin-gallate hybrids were synthesized and assessed, with compound 3b showing significant in vitro antioxidant and cytotoxic activities, and the series displaying moderate efficacy in inhibiting coronavirus activity through in silico analysis.

This study found that the methylation level at CpG III site 4 of the KRT17 gene promoter significantly influences wool production in Angora rabbits, suggesting its potential as an epigenetic marker for breeding high wool yield.

This case study reported a rare occurrence of cicatricial alopecia linked to zolpidem-induced sleep-related amnestic behavior, highlighting the importance of a comprehensive medication history for accurate diagnosis.
