This study observed distinct post-marketing safety signal patterns for baricitinib and tofacitinib in adult AA, influenced by their differing regulatory uses and real-world contexts, and emphasizes the need for future studies to validate these findings.

This study presented a new wearable textile-based device with near-infrared OLEDs that significantly reduced cell aging markers and improved cell migration in vitro, suggesting it as a promising, non-invasive phototherapy option for hair follicle treatment and hair-loss management.

This study observed that in individuals with stroke, the GNRI has a significant negative association with FI and FISI, mediated by the SII index and OBS, suggesting the importance of anti-inflammatory and antioxidant strategies to reduce FI risk.

This study on Dorper sheep identified important genetic factors influencing hair follicle development, finding that expression patterns and genes like DBI, FZD3, and ZDHHC21 play a crucial role in wool shedding, which could help improve understanding of mammalian skin-related traits and human hair advancement.

This study found that extracts of mesenchymal stem cells (MSC-extract) and their protein components (MSC-protein) enhanced the proliferation and migration of periodontal ligament cells and induced significant periodontal tissue regeneration, showing potential as a new cell-free treatment for periodontal disease.

This study analyzed data from 2083 patients with alopecia areata in Europe and found that those with atopic, autoimmune, or psychiatric comorbidities encountered more severe disease and were more likely to require advanced treatments compared to those without comorbid conditions.

This review of Cedrus libani highlights its potential as a source of natural antioxidants and antimicrobials and notes that it may offer analgesic and anti-inflammatory benefits; however, further toxicological and clinical studies are necessary to confirm its safety and efficacy for treating human diseases.

This study found that Sol/ASC-DP nanoparticles could enhance the skin permeability of minoxidil due to improved stability and hydrophobic interactions in the nanoparticle structure.

This research explores if COVID-19, analogous to SARS-CoV, may result in long-term pulmonary fibrosis in recovered patients, although current evidence on the persistence or resolution of lung changes over time remains unknown.

This study provides new insights into the identification and expression patterns of miRNAs in wool follicles, which could improve understanding of wool follicle development in sheep.

This review discusses definitions of polycystic ovary syndrome and reports no new clinical results; the authors support using modified 1990 NIH criteria and acknowledge ongoing evolution as research advances.

This review discusses the definition of polycystic ovary syndrome proposed by the AE-PCOS Society Task Force, emphasizing hyperandrogenism, ovarian dysfunction, and excluding related disorders, while noting potential variations needing more research.

This review examines the relationship between polycystic ovary syndrome and cardiovascular disease risk, but reports no new clinical findings; the panel calls for guidelines to prevent CVD in this population.

This paper reviews the diagnostic criteria, etiological factors, and treatment approaches for PCOS, highlighting the importance of considering metabolic issues such as insulin resistance and obesity, but reports no new findings.

This review discusses the neurobiology of sexual function and reports no new results; the authors cover multiple endocrine and neurotransmitter influences on sexual desire, arousal, and orgasm stages.

This study found that IL-17A-producing γδ T cells play a key role in bone fracture healing by promoting bone formation, with deficiencies leading to impaired repair in mice.

This study found that altering cell culture conditions to form three-dimensional papilla spheroids can restore the ability of human dermal papilla cells to induce hair growth in adult skin.

This review discusses the role of 5α-reductase in prostate development and BPH, and reports no new clinical results; ongoing trials are exploring dual isozyme inhibitors for improved treatment efficacy.

This review explores possible reasons for why male COVID-19 patients experience more severe symptoms and higher fatality rates than female patients but provides no new clinical results.

This review discusses recent advances in skin penetration mechanisms, specifically focusing on the enhanced understanding of the follicular pathway and its implications for transdermal therapies, immune system targeting, and nanoparticle safety.

This article discusses the influence of estrogens on hair follicle growth and metabolism, suggesting a significant role alongside androgens in hair growth control but reports no new clinical results.

This review examines the functions of vitamin D and its receptor in skin and explores how these are regulated, reporting no new clinical results.

Humans lost body hair relatively recently in evolution.

This article provides contact information for Bruce A. Morgan and features no new research findings.

This review discusses how Western diet may contribute to acne vulgaris through insulin signaling and metabolomic changes, promoting a dietary approach for management, but reports no new experimental results.

This study demonstrated that stress inhibited hair growth in mice, likely through substance P-dependent activation of immune cells, highlighting a brain-hair follicle connection.

This study highlights that the ACIP strongly recommends COVID-19 vaccination and booster doses for pregnant women, those breastfeeding, or trying to conceive, due to the safety of non-live vaccines in these groups and the protection they also offer to infants.

Different ethnic groups have unique hair growth patterns, with African hair growing slower and less dense, Asian hair growing fast but sparse, and Caucasian hair being densest; men are more likely to experience hair loss than women.

This review discusses the potential use of liposomal formulations to enhance the effectiveness of cosmeceutical delivery through the skin barrier, with no new clinical results reported.

This paper reviews the use of interferons, particularly alfa interferon, in treating cutaneous T-cell lymphoma, noting its substantial efficacy both alone and in combination therapies with predictable, generally well-tolerated side effects.
