This review discusses the links between particulate matter exposure and skin diseases, highlighting oxidative stress and inflammation as key mechanisms; it reports no new clinical results.

The guidelines advise against using testosterone and DHEA in women for most conditions due to safety and effectiveness concerns, but suggest considering testosterone for postmenopausal women with low sexual desire.

This review explores the hypothesis that polycystic ovary syndrome may originate in fetal life due to genetic predispositions and environmental influences, but it reports no new clinical findings.

This review discusses strategies for developing semi-solid topical generic products to match the quality of reference-listed drugs, using concepts like quality by design and reverse-engineering, but reports no new results.

Epirubicin is as effective as doxorubicin for cancer treatment with less heart damage, but doesn't work on doxorubicin-resistant cancers.

This literature study reviews the consequences of hair loss due to chemotherapy and nursing care interventions but reports no new clinical results.

This study found that keratin K14 expression occurs early in epidermal cell differentiation, while a hair-specific keratin is expressed later in hair matrix cells, suggesting developmental divergence between the two cell types.

This study found that dermal Shh signaling regulates specific dermal papilla signatures essential for maintaining hair follicle development, suggesting that the Shh-Noggin signaling loop is crucial for hair morphogenesis.

This review summarizes recent advances in Treg cell biology, focusing on Foxp3's role in immune regulation and therapeutic reprogramming for immune dysregulatory disorders, but reports no new clinical results.

This review examines the epidemiology, pathophysiology, diagnosis, and management strategies for non-classic congenital hyperplasia due to 21-hydroxylase deficiency, and provides evidence-based recommendations for its treatment and genetic counseling.

This review discusses various treatment options for adult female acne, highlighting the need for tailored approaches due to individual patient needs and reports no clinical outcomes.

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 identified a distinct "exogen" phase in the hair cycle during which hair shedding occurs, primarily coupled with the anagen phase, rather than as part of the telogen phase.

This article provides guidelines for molecular genetic testing of congenital adrenal hyperplasia due to 21-hydroxylase deficiency, focusing on quality requirements, methodologies, and variant classification; it reports no new clinical results.

This study found that the transcription factor p63 is crucial for horizontal basal cell differentiation in the olfactory epithelium, suggesting a p63-dependent mechanism activates reserve stem cells after injury.

This study found that serum androgen levels in premenopausal women may be influenced by genetic variants of the androgen receptor and estrogen receptor β genes.

This study found that the retinoid all-trans retinoic acid induced a catagen-like stage in human scalp hair follicles, suggesting upregulation of TGF-beta2 as a contributing mechanism.

This review discusses different preparation and application methods of platelet-rich plasma in dental regenerative medicine and reports no new results, highlighting its potential and associated controversies.

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 article discusses the complexities of diagnosing and managing polycystic ovary syndrome in adolescents and highlights the lack of established diagnostic criteria and unclear clinical implications, without presenting new clinical findings.

This review suggests that isotretinoin's effects on severe acne and various cancers may result from apoptosis, which might also explain its adverse effects through genetic variability.

This review found that infliximab, golimumab, and some forms of radiotherapy significantly improved nail psoriasis compared to controls, although they could have serious adverse effects and are not commonly used specifically for nail issues.

This study found that men receiving enzalutamide and other androgen-deprivation therapies may be at increased risk for QT prolongation and torsades de pointes.

This study found that brain-derived neurotrophic factor (BDNF) inhibited hair shaft elongation and induced premature catagen development in cultured human hair follicles, partially through transforming growth factor β2.

This review discusses the physiological roles of ovarian androgens in follicle development and atresia, emphasizing their contributions to polycystic ovary syndrome and normal follicle maturation but provides no new clinical results.

This review discusses the incidence, reversibility, and impact of chemotherapy-induced alopecia and concludes that scalp cooling is the most effective prevention method in most cases, though some questions remain.

Certain fungi and bacteria help orchid seeds germinate and plants grow better.

This study reports that C3H/HeJ mice and DEBR rats serve as effective models for screening potential treatments for human alopecia areata, despite certain challenges in predictability and cost.

In this study, researchers observed that hyperandrogenic PCOS patients exhibited distinct miRNA and TGFβ signaling gene expression patterns in granulosa cells, suggesting these factors may play a role in PCOS pathogenesis.

This review explores lifestyle modifications for women with polycystic ovary syndrome, discussing dietary, physical, and supplementation strategies, but reports no new clinical results.
