This study investigated the formation of a specific chemical crosslink in hair proteins and explored the role of transamidase enzymes in hair follicles.

This review analyzes the traditional Iranian medicine uses of Citrullus colocynthis and compares them with modern phytotherapy findings, reporting no new clinical results but noting safety concerns and dosage considerations.

This systematic review suggests that current evidence does not support routinely discontinuing gender-affirming hormone treatments before surgery, especially testosterone and spironolactone, due to limited data on related perioperative risks.

This study observed that androgen treatment increased ROS production and TGF-β1 secretion in rat hair follicle dermal papilla cells, suggesting that the androgen-induced TGF-β1 is mediated by ROS.

This study found that vertical sections of alopecia biopsy specimens had a higher concordance rate with the original combined diagnosis compared to transverse sections alone, although both methods have their pros and cons.

This study suggests that changes in expressed transcripts and splice isoforms may explain the transition from curly to straight fleece in Chinese Tan sheep as they age.

This study reports that corneal transient amplifying cells can be reprogrammed into epidermal cells capable of forming hair follicles in response to embryonic dermis signals.

This study found that human keratinocytes express a sodium-dependent multivitamin transporter for biotin, pantothenic acid, and lipoic acid, including a highly specific biotin transport component.

This review discusses hairstyling practices in the black community linked to traction alopecia, categorizes them by risk, and offers guidance for dermatologists on management and patient education but reports no new clinical results.

This study found that the microRNA miR-22 is a key regulator of the hair cycle, influencing hair loss by promoting the transition from growth to rest phases and repressing keratinocyte differentiation.

This study found that human hair follicle stem cells formed more colonies and adhered more rapidly, while transit-amplifying cells showed significantly greater mobility.

This review highlights the potential of permeation enhancers to improve the delivery of active ingredients across the skin, optimizing therapeutic outcomes despite challenges posed by individual variability and environmental factors, according to the authors' analysis of current understanding and applications in skincare and transdermal therapies.

This study measured the lengths and depths of different portions of occipital scalp hair follicles and suggested cutting below 1 mm for hair regeneration procedures to avoid damaging the bulge zone.

This study found that Transcutol-containing vesicles improved the delivery of minoxidil to deeper skin layers in vitro but did not facilitate its permeation through the skin.

This study found that transgenic mice expressing human keratin K8 in the epidermis showed increased progression of skin lesions toward malignancy, suggesting a role for K8 in the development of invasive skin cancer.

Transamidases are present in the epidermis but their exact role is unclear.

This review discusses transdermal drug delivery using hydrogel-forming microneedles and highlights their potential for disease treatment, but notes challenges in their clinical application.

This review found an increasing trend in research on sperm DNA fragmentation over the past 20 years, especially focusing on lifestyle factors, asthenozoospermia, and varicocele, with the TUNEL technique as a predominant method.

In this study, researchers introduced calcium carbonate-based carriers for transdermal drug delivery, observing efficient transport of substances and systemic absorption in rats, suggesting potential applications in regenerative medicine and dermatology beyond conventional topical treatments.

This study found that dimethylarsinic acid significantly accelerates skin tumor development in hair follicle-targeted K6/ODC transgenic mice.

This study observed that targeted expression of the neu oncogene in transgenic mice led to significant epidermal hyperplasia and a carcinoma-like appearance, suggesting a crucial role for erbB2 signaling in epidermal proliferation and carcinogenesis.

This research observed that during the catagen phase, the inner root sheath of hair follicles becomes an early target, highlighting its potential role in maintaining hair follicle homeostasis.

This study identified key genes and miRNAs involved in feather morphogenesis in Zhedong White geese, highlighting a negative correlation between FOXO3 and miR-144-y.

This study demonstrated that a specific 9-kbp fragment of the bovine keratin 6 gene effectively directs tissue-specific and inducible expression in transgenic mice, suggesting potential applications for targeted gene therapy in hyperproliferative skin conditions.

This study identified morphotype-specific gene expression patterns in feathers, enhancing understanding of the molecular and cellular processes involved in feather development and diversification.

This study found that D'orenone blocks root hair growth by increasing PIN2 protein abundance, leading to reduced auxin concentration, but external auxin can reverse these effects.

Hair transplantation successfully treated a woman's hair loss caused by a tight ponytail.

This study found that transgenic mice overexpressing the SSAT gene under a metallothionein promoter suffered delayed hair loss and were highly sensitive to polyamine analogues, which led to significant liver changes and mortality.

This review summarizes the use of 3D printing technologies for creating microneedles and evaluates their associated benefits, challenges, and regulatory considerations, but does not present new experimental results.
