This review indicates that estrogen loss during menopause significantly impacts skin health, while estrogen treatment may increase skin collagen, thickness, and elasticity, though effects on other skin characteristics are inconsistent.

This study observed specific expression patterns of three zebrafish estrogen receptor genes during development, highlighting robust co-expression of esr2a and esr2b in primary neuromasts, branchial arches, and other tissues.

This study found that cyclosporin A treatment enhances hair growth in mice by inhibiting calcineurin-NFAT1 activity, which alters keratinocyte differentiation and apoptosis-related gene expression in hair follicles.

This study found that Insig deficiency in the skin of mice causes cholesterol precursors to accumulate, leading to defective hair development and skin abnormalities, which were alleviated by simvastatin treatment.

This study found that reducing BMP signaling in mouse nipple epithelia, achieved through Noggin overexpression, can convert them into hairy skin with pilosebaceous units.

In this study using a mouse model and human hair follicle cells, shikimic acid was found to promote hair growth and may serve as a new therapeutic agent for alopecia.

This study found that dual 5α-reductase inhibition in rats led to decreased sperm motility and altered morphology, resulting in subfertility.

This review discusses the strategies and progress in developing bioengineered organ replacement therapies but reports no new clinical results, highlighting the potential for future regenerative solutions.

In this study, researchers reported that CD34 expression in the isthmic region of canine hair follicles suggests a potential stem cell compartment in this area.

This study found significant differences in gene expression between newborn and adult skin, with infant skin notably increasing processes related to ECM organization, cell adhesion, and collagen fibril organization.

Saw palmetto extract can block the enzyme that converts testosterone in pig prostate cells.

This study reports that 4-(alkylthio)- and 4-(arylthio)-benzonitriles showed moderate sebum reduction as androgen receptor antagonists when applied topically in a validated animal model.

Among cultured sebocytes, this study found that bilobetin significantly inhibited lipid production induced by IGF-1, suggesting potential for use in acne treatment.

In this review, the authors aim to improve the differential diagnosis between hyperandrogenic PCOS and NCAH, which could lead to more personalized treatment strategies for patients experiencing hyperandrogenism.

This study developed a new proteomic method to identify and assess ancient hair proteins using only small amounts of sample, providing insights into hair protein alteration processes over time.

Diphenyl ethers can potentially reduce excess oil production when applied on the skin, helping treat conditions like acne.

This review discusses current airway regeneration research efforts and reports no new experimental results, highlighting the need for clinical interventions to enhance airway repair.

This study found that an imbalance of selenium in a C57BL/6 mouse model led to hair loss with color change and was linked with changes in hair follicle apoptosis markers.

This review covers the current procedure for follicular unit hair transplantation, noting that recent advancements have made the results natural and undetectable, but it presents no new experimental findings.

In this article, the authors reviewed essential terminology and recommendations for creating a welcoming healthcare environment for transgender patients and providing gender-affirming therapy, emphasizing the unique health needs and disparities faced by this population.

This study synthesized and characterized new 2-hydroxypyrrolidine/piperidine derivatives using FeCl₃·6H₂O as a catalyst, but it reports no biological or clinical results.

This study found that platelet-rich plasma improved the healing of skin wounds in sheep compared to honey by reducing early inflammation and enhancing collagen synthesis and organization.

This study found that Oriental melon leaf extracts promoted hair growth in a mouse model and cultured human hair follicles, suggesting potential use as a treatment for hair loss.

This study reported that CoFe2O4 magnetic nanoparticles efficiently catalyzed the synthesis of minoxidil from 2,6-diamino-4-chloro-pyrimidine N-oxide, achieving a 95% yield with sustained reusability.

This study found that the metabolic profile of finasteride in pigs closely matches that of humans, supporting the use of pigs for studying human drug metabolism.

This study reviewed 54 articles to examine how continuous exposure to air pollution causes hair damage, hair loss, and scalp conditions due to oxidative stress and inflammation, and highlighted anti-inflammatory substances that could mitigate these effects.

This study examined the relationship between asprosin levels and polycystic ovary syndrome, finding no statistically significant difference in asprosin levels between patients and healthy controls, although differences in fetuin a levels were significant.

This review discusses the role of ferritin in iron homeostasis and its potential utility in diagnosing iron deficiency as a cause of hair loss, while noting that ferritin's impact on skin and hair disorders is not fully understood.

This article discusses the limitations of relying on literature and regulatory documents for pharmaceutical evidence, proposing public health decisions be based on independent trials like those by the Mario Negri Institute.

This study outlined the complexities of common scalp conditions like dandruff and alopecia, emphasizing the need for comprehensive treatment strategies that include modern diagnostic techniques and address underlying factors to enhance therapy effectiveness and improve patients' quality of life.
