This report describes a 27-year-old patient with Ehler-Danlos syndrome who also presented with hypophosphatasia and mastocytosis, and suggests enzyme replacement therapy might alleviate symptoms in such overlapping genetic conditions.

This review discusses the uses and toxicological data of eleven unsaturated halogenated hydrocarbons, including dichloroacetylene, allyl chloride, hexachlorobutadiene, β-chloroprene, vinyl chloride, trichloroethylene, and perchloroethylene, but presents no new findings.

This study found that human peptidylarginine deiminase type III is the predominant isoform in hair follicles and may modulate structural proteins during hair and hair follicle formation.

This study identified a germline variant in PLCD1 as a major risk allele for familial trichilemmal cysts, requiring a subsequent somatic mutation in the same allele for cyst formation.

In this study, topical phenylephrine significantly reduced hair shedding and increased the force needed to pluck hair in women undergoing cosmetic procedures, suggesting its potential utility for traction alopecia.

This study identified several genetic variants associated with cattle hair coat length, which may help breed more heat-tolerant animals by facilitating efficient heat loss.

This study found no statistically significant relationship between androgenic alopecia and the PON1 ML55 and QR192 genetic polymorphisms, despite a higher frequency of the PON 55 L allele in patients.

This article reports that mutations in the PADI3 gene, affecting its activity or localization, cause uncombable hair syndrome and are linked to central centrifugal cicatricial alopecia, particularly among women of African ancestry.

This study concluded that pseudopelade is an autosomal dominant condition, distinct from other forms of alopecia, characterized by atrophic hair follicle loss and notable familial association.

This study found that mice lacking sPLA2-IIE had distinct skin abnormalities, particularly affecting hair follicles, highlighting the differing roles of sPLA2 isoforms in mouse skin.

This study found that topical diphenylcyclopropenone was effective in treating severe alopecia areata but had a high relapse rate and was often accompanied by side effects like eczema and lymphadenopathy.

This study found that the collagen-binding fusion protein PTH-CBD significantly improved hair regrowth and follicle health in mice after chemotherapy, suggesting potential as a therapy for chemotherapy-induced alopecia.

This study identified a cytochrome P450 enzyme, CYP-pa1 from Pseudonocardia autotrophica, as responsible for the specific hydroxylation of cyclosporin A at the 9th N-methyl leucine, suggesting potential for biotechnological applications.

Researchers found a new mutation in the HR gene causing hair loss and skin bumps in a Pakistani family.

This study found that cepharanthine can inhibit gastric cancer cell activity by inducing oxidative stress and altering energy metabolism, suggesting its potential for gastric cancer treatment.

This study found that a significant portion of alopecia areata patients achieved at least partial hair regrowth with diphenylcyclopropenon therapy, which was more effective in certain subtypes and disease durations.

In this study, PA-011, a traditional Chinese medicine extract, was shown to improve hair growth in alopecia areata model mice by reducing skin inflammation and altering skin microbiota, indicating its potential therapeutic role for this condition.

In this study, a new formulation of human placental extract showed antioxidant and neurite outgrowth activities, significantly reduced hair graying in mice, and alleviated neuropathy symptoms, suggesting potential therapeutic benefits.

In this case report, a 9-year-old boy with diffuse alopecia areata showed improvement with topical diphencyprone immunotherapy, suggesting it as a safe and effective treatment option in pediatric cases of alopecia areata resistant to other therapies.

Certain peptides can prevent hair loss in young rats caused by a cancer drug.

This study found that the small signaling peptide RALF22 plays a key role in root hair growth response to volatile compounds emitted by Penicillium aurantiogriseum through ethylene, auxin, and photosynthesis signaling in Arabidopsis.

This study identified a 69 bp deletion in the KRT75 gene as the cause of the frizzle feather trait in chickens, affecting feather curling.

This case study reports that a 35-year-old woman developed nonscarring alopecia following the cosmetic use of poly-L-lactic acid on her face and hairline.

This study identified a compound heterozygous mutation in a hairless rhesus macaque, which was associated with skin abnormalities similar to those in hairless mice and humans with APL.

This study found that elevated TSPEAR expression in colorectal cancer was associated with poor overall prognosis and correlated with tumor infiltrating immune cells, suggesting its potential as a predictive biomarker.

This study found that increased PHGDH expression in mice led to earlier melanin and melanocyte presence in hair follicles but did not induce cancer.

This study found that a hair conditioner using peptides from Pneumatophorus japonicus heads improved damaged hair's structure, gloss, and smoothness more effectively than a commercial wheat protein conditioner by increasing amino acid content and interacting with hair keratin.

This study found that PPARα agonists provided protective effects in mouse models of alopecia areata by promoting early reversal of the condition and inhibiting T effector cell function, indicating potential therapeutic value for this inflammatory condition.

In this study, PP-PTKL exhibited antioxidant, anti-inflammatory, and pro-melanogenic effects in laboratory settings, suggesting its potential role in preventing or treating hair greying. Further animal and human studies are needed to verify these findings.
