This study found that keratin 17 and TNFα play interdependent roles in regulating hair follicle cycling, with TNFα required for the anagen–catagen transition and its ablation partially rescuing hair cycling defects in K17-null mice.

This study found that PRP combined with dalteparin and protamine microparticles may enhance hair growth by increasing hair thickness compared to PRP alone.

This study found that women with androgenetic alopecia or alopecia areata have significantly lower serum ferritin levels than those without hair loss, suggesting a potential link between these types of alopecia and decreased iron stores.

This review discusses the effects of estrogen on skin and reports no new clinical results; it highlights estrogen's potential benefits on skin thickness, collagen quality, and hair follicle life cycle.

This review explores recent findings on regulatory T cells, focusing on their unique functions in non-lymphoid tissues and new mechanisms of action, but presents no original clinical results.

This systematic review found that Janus kinase inhibitors have shown beneficial effects for psoriasis and alopecia areata, with promising preliminary results in other skin conditions, though more research is needed to define dosing and safety profiles.

This study found that women with polycystic ovary syndrome have higher rates of nonalcoholic fatty liver disease, with androgen excess contributing to the risk.

This study found that fibromyalgia prevalence is slightly higher in patients with systemic lupus erythematosus compared to those with arthritis, but fibromyalgia-ness does not bias the SLE Activity Questionnaire.

This study concluded that daily treatment with 1 mg finasteride did not affect spermatogenesis or semen production in young men and had small, reversible effects on prostate volume and serum PSA.

In this study, researchers found that androgenetic alopecia significantly harms quality of life, particularly in younger patients, those with more severe or long-term alopecia, and those who have sought non-medical hair care.

In this study, tapering prednisone followed by 2% topical minoxidil helped limit hair loss in some patients with alopecia areata, with 30% to 47% showing over 25% hair regrowth initially.

This review discusses the etio-pathogenetic factors in benign prostatic hyperplasia and their role in the development of lower urinary tract symptoms but reports no new research findings.

This study found that traction alopecia risk was higher in adults than children and increased further when traction was combined with chemically relaxed hair.

In this study, older men using 5α-reductase inhibitors for prostatic enlargement did not show increased risk of suicide, but had elevated risks of self-harm and depression.

This review discusses the essential roles and complex regulation of PP2A in various physiological processes and reports no clinical results; the authors highlight the need for further mouse model research to explore PP2A's therapeutic potential.

This study found that early-onset androgenetic alopecia in individuals of European ancestry is significantly associated with increased odds of Parkinson's disease and is influenced by specific genetic loci, including some linked to reduced fertility.

This review discusses the role of Wnt/β-catenin signaling in hair follicle regeneration and highlights recent progress in developing hair loss treatments targeting this pathway, but reports no new clinical results.

This study reported that women with PCOS had higher levels of depression, anxiety, and perceived stress compared to those without PCOS, with stress potentially mediating these associations.

This review discusses the features of regulatory T cells and the modulation of Foxp3, emphasizing post-translational modifications' impact on Treg function but reports no new clinical results.

This study found that stimulating the olfactory receptor OR2AT4 in human hair follicles with a synthetic sandalwood odorant promotes hair growth ex vivo by decreasing apoptosis and increasing IGF-1 production.

This review explores animal models of alopecia areata, particularly focusing on the insights they've provided into the disease's immune mechanisms and potential treatment approaches, without reporting new experimental data.

This study found that the AR-E211 A allele is associated with a lower risk of both metastatic prostate cancer and androgenetic alopecia in an Australian population.

This review discusses the therapeutic potential of costunolide for various diseases, highlighting its bioactivity and mechanisms, but it reports no new experimental results.

This study found that blue light at a wavelength of 453 nm promoted hair growth ex vivo, potentially through interacting with OPN3 receptors in human hair follicles.

This study found that PRO 160/120 and Finasteride showed similar effectiveness in improving urinary symptoms and quality of life in patients with benign prostatic hyperplasia over 48 weeks.

Hormonal treatment in transgender women reduces semen quality, but stopping treatment may improve it.

This study found that in thin cutaneous melanomas, tumor regression is associated with a higher risk of sentinel lymph node involvement.

This study found that endocrine therapy for breast cancer is associated with a pattern of hair loss similar to androgenetic alopecia, negatively impacting quality of life despite mild severity.

This article reviews the role of perifollicular regulatory T cells in maintaining hair follicle integrity in the context of hidradenitis suppurativa and calls attention to inflammatory mechanisms without reporting new clinical results.

This review discusses how macro-environmental factors such as intradermal adipose tissue and sex hormones influence hair and feather stem cell niches, suggesting environmental targets for regenerative medicine, but reports no new clinical results.
