In this study, a specific retinoic acid receptor antagonist caused severe craniofacial anomalies in mouse fetuses when administered early in pregnancy, but not limb anomalies, highlighting developmental stage-specific roles of retinoic acid.

This study found that treatment with ritlecitinib or brepocitinib was effective in improving scalp hair loss for patients with alopecia areata over 24 weeks compared to placebo.

This study used machine learning to identify molecular predictors of drug response in alopecia areata, suggesting a tool for predicting treatment efficacy based on gene signatures.

In this study, researchers developed an optimized formulation of a traditional ethnomedicinal recipe from East Nusa Tenggara, which demonstrated strong antioxidant activity and significantly enhanced hair growth in a mouse alopecia model, compared to control groups.

This study found that the methanolic heartwood extract of Avicennia marina significantly inhibited the enzyme 5 alpha-reductase type 1 in a cell-based assay, suggesting potential anti-androgenic effects for treating androgenic alopecia.

In this research, Sertoli cell line model ST38c demonstrated that the androgen receptor regulates hormone pathways through specific coregulators, suggesting roles for SRC-2 and HBO1 in testicular development and androgen responsiveness.

The study found that a pomade containing bay leaf extract significantly promoted hair growth in New Zealand White rabbits, with the 30% extract formula demonstrating the highest growth compared to lower concentrations and a control without extract.

This study found that a specific amino-pyridine compound showed potent androgen receptor antagonist activity, stimulating hair growth in mice and reducing sebum production in a hamster model.

This study found that in female androgenetic alopecia, androgen receptors are highly positive in affected areas, supporting their role as regulators of genetically predisposed hair follicles despite normal serum hormone levels.

This study found that a 30 Gy radiation dose was most effective in an experimental rabbit model of radiodermatitis, causing significant tissue changes and prolonged effects compared to lower doses and a control group.

This study observed that hairless HRS/J mice were resistant to Bacillus anthracis infection at the skin's surface, suggesting resistance may be due to increased dermal neutrophils rather than non-functional hair follicles.

This study aimed to determine the phenolic compound composition in Equisetum arvense stem extracts using HPLC, as the plant is commonly used in cosmetics for skin and hair care, but results are not reported here.

This study observed that the compound EM-402 reduced 5α-reductase activity and sebaceous gland size in the flank organs and ears of hamsters, indicating potent localized anti-androgenic effects without systemic action.

The abstract highlights that a thorough physical examination, including specific considerations like umbilical examination and joint palpation, is crucial for diagnosing and managing the health of neonatal ruminants, as reported in this guide for veterinarians.

Baricitinib helps regrow hair in teens with severe alopecia areata.

This study found that MOOEW Hair Tonic had a Return of Investment of over 100%, indicating significant potential for profitable and sustainable business opportunities.

This study found a recurrent nonsense mutation in the HR gene linked to atrichia with papular lesions in two Kashmiri families, suggesting whole exome sequencing as an efficient method for diagnosis and genetic counseling.

This study reported that acupuncture combined with topical Aloe vera and celery gel reduced hair loss from alopecia androgenetica after 28 days of treatment.

This study identified a mutant in Arabidopsis with shorter root hairs due to early growth cessation, implicating the IRE gene in regulating root hair growth duration.

In this case report, a 1.5-year-old Pomeranian named Beb with respiratory and skin issues was diagnosed with pneumonia and demodecosis; following a two-week treatment including antibiotics, ivermectin, and supportive care, Beb's symptoms resolved, and hair regrowth was observed.

This study reports that a sarcoptic mange outbreak, likely originating from mange-infected llamas from a governmental program, dramatically reduced vicuña and guanaco populations in San Guillermo National Park, Argentina.

This study demonstrated that an AR-EGFP transgene can restore AR function and fertility in Sertoli cell-specific AR knockout mice, highlighting its potential use in understanding androgen receptor functions.

This study found that patients with alopecia areata have distinct mRNA and lncRNA expression profiles between normal and bald scalp areas, identifying differentially expressed genes and revealing potential biomarkers for diagnosis, with keratin family genes possibly playing a key role in the disease's pathogenesis.

In this study, a novel compound named AH-001 demonstrated effective androgen receptor protein degradation, reducing hair loss progression in a mouse model of androgenetic alopecia, with minimal systemic exposure and side effects, suggesting potential for safer treatment.

This study used infrared spectroscopic imaging and scanning electron microscopy to reveal that alopecic hair has more irregular laminated structures and differing chemical profiles than normal hair, suggesting changes related to alopecia progression.

This review examines the potential roles of azathioprine and methotrexate in treating alopecia areata, concluding that both can be effective as monotherapy or in combination therapy.

This study presents a DNA-analytical method that can reliably identify and differentiate cashmere, fine wool, yak, and camel hair fibers in both untreated and processed samples.

This study in Gansu alpine fine-wool sheep identified two SNPs in the KRT71 gene that significantly affect wool length, with distinct expression patterns observed in hair follicles, suggesting KRT71 as a candidate gene for enhancing wool production traits.

This abstract outlines the genetic and biological processes of hair growth, highlighting that various hair disorders can have significant medical, aesthetic, and psychological impacts, though specific research findings or results were not reported.

This review discusses nonsteroidal selective androgen receptor modulators and their potential therapeutic applications but reports no new clinical findings.
