In this study, researchers found that glycan profiles in epidermal stem cells differed between young and old mice, suggesting these changes may serve as molecular markers for aging.

In a study on the effects of stromal vascular fraction (SVF) and platelet-rich plasma (PRP) on hair growth in nude mice, researchers found that both treatments promoted hair growth, with SVF showing a stronger effect.

This study found that double-fermented green coffee bean extracts displayed strong antioxidant, anti-inflammatory, and dermal papilla cell growth-promoting activities, suggesting potential use in cosmetics for scalp and hair health.

This study observed significantly higher hair cortisol concentrations in foals compared to mares, with a strong positive correlation between the two, suggesting that hair cortisol can reflect maternal and fetal cortisol exposure during the last trimester of gestation in horses.

This study found that psoriasis patients on biologic therapy had significantly lower anti-COVID19 IgG antibody levels after vaccination compared to healthy individuals not on biologic treatment.

This study found that Samhwang-Sasimtang herbal extract may enhance hair growth in mice, as indicated by increased hair follicle activity and reduced growth inhibition factors compared to a control.

This review discusses the hormonal and genetic factors influencing acne development, emphasizing the role of androgens and insulin signaling but reports no new clinical results.

This study found that mesenchymal cell processes from the dermal papilla contact epithelial hair matrix cells through gaps in the basal lamina during hair matrix cell differentiation in mouse vibrissa follicles.

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 the role of cytochrome P450 enzymes in skin metabolism and drug development for skin diseases, highlighting their importance and suggesting further research, but reports no new experimental findings.

This study validated a method for measuring cortisol levels in hair, which may serve as a biomarker for chronic stress in both humans and various animals.

This study found that certain C57BL/6 mouse substrains have a genetic vulnerability to skin lesions resembling central centrifugal cicatrical alopecia in humans, potentially worsened by high vitamin A levels.

The researchers found that plant extracts from Papaver rhoeas L., Clitoria ternatea L., and Carthamus tinctorius L. are effective natural cosmetic dyes, offering intense and stable colors without cytotoxicity.

This study found that the S. epidermidis A/C lineage is more pathogenic due to its metabolic and genomic versatility, which allows it to adapt quickly from a commensal to a pathogenic lifestyle.

In this study, researchers observed a significant association between female androgenetic alopecia and coronary artery disease in women under 55, supporting a link similar to that seen in men.

This study found that overexpression of sPLA2-X in mice was associated with alopecia and hair follicle abnormalities, highlighting its potential role in hair follicle homeostasis.

This review discusses recent advancements in therapies for ichthyosis, highlighting promising prospects in protein replacement and gene therapy, but it reports no new clinical results.

This article discusses the role of sex hormones in COVID-19 fatality differences between sexes and reports no new clinical results, suggesting that future strategies should consider sex-specific approaches.

A specific mutation in PA-PLA1α causes abnormal hair growth.

In this study, women with the GG polymorphism of the MMP1 gene promoter were found to have a higher likelihood of being diagnosed with polycystic ovary syndrome.

In a study on mice, cow placenta extract showed strong antioxidant activities and reduced collagen damage, suggesting it could help delay skin aging caused by D-galactose.

Hair enzyme activity predicts minoxidil success in Brazilian women with hair loss.

This study found that diazepam had an exaggerated effect on GABA-related inhibitory tone in diabetic neuropathic mice compared to normal mice, potentially due to mitochondrial dysfunction affecting neurosteroid synthesis.

This review discusses recent advancements in responsive-hydrogel dressings for diabetic wound healing, highlighting their design, responsiveness, and degradation behavior, and evaluating their potential advantages and limitations in clinical applications.

This study found that diazepam has an exaggerated effect on GABAergic inhibitory tone in diabetic neuropathy mouse models, likely due to upregulated neurosteroidogenic enzymes responding to mitochondrial dysfunction.

This article reviews the presentations from the First Symposium of Ichthyosis Experts in Spain, held to address the challenges in organizing care for ichthyosis patients, and reports no new clinical results.

This study reviewed the evidence on minoxidil's effectiveness for androgenetic alopecia, finding that 5% topical minoxidil is the most effective monotherapy for men, while 2% is similarly effective for women. Genetic markers can predict response, and new formulations like foam and gel improve tolerability.

This source reports that for treating keloids and hypertrophic scars, combination pharmacotherapy targeting multiple sites is generally more effective than using a single drug, though outcomes of individual therapies vary and the development of satisfying treatments is ongoing.

This study found increased infiltration of specific immune cells, such as γδ T cells and CD8+ T cells, in the bald scalp of male androgenetic alopecia patients, and identified four key immune-related genes potentially involved in hair loss development through interferon-γ signaling pathways.

This study reported that black sesame oil significantly stimulated hair regrowth in mice, suggesting its potential for promoting hair growth or preventing hair loss in humans.
