This article reviews the complex signaling pathways between epithelial and mesenchymal cells crucial for hair follicle morphogenesis, highlighting the Wnt pathway's role as a master regulator without reporting new experimental findings.

This study highlights that the mammalian target of rapamycin complex 2 (mTORC2)-Akt signaling axis is essential for hair follicle stem cells to return to their niche and regenerate effectively by regulating metabolic pathways.

In this study, higher expression levels of aromatase and steroidogenic acute regulatory protein were correlated with increased estrogen synthesis and fewer hair follicles in human skin, suggesting a link to elastic fiber formation and hair growth.

This study found that finasteride treatment in male rats led to enduring effects on depressive-like behavior, hippocampal neurogenesis and neuroinflammation, and gut microbiota composition after withdrawal.

This study found that Pep-1-mediated mitochondrial transplantation was as effective as PRP therapy in restoring hair loss related to aging in mice, with distinct improvements in hair and skin-related measures.

This study found that, among fertile egg donors, the AR gene CAG polymorphism was associated with differences in antral follicle count but did not impact ovarian response to gonadotrophins.

This article describes how PESCADOR software assists in creating detailed biological pathway charts from PubMed abstracts, focusing on hair and breast development case studies without providing new clinical results.

This study reported successful recovery of biologically active recombinant murine Wnt3a without detergent, suggesting usefulness for structure-activity studies avoiding detergent-related issues.

This study documented a case where Ayurvedic treatments for plaque psoriasis significantly reduced the severity of symptoms, as measured by an 84% improvement in the Psoriasis Area and Severity Index score from 6.5 to 1.04.

This study found that combining platelet-rich plasma with 4% hydroquinone was more effective in reducing melasma symptoms than using hydroquinone alone.

This article reviews the impact of Covid-19 vaccinations on disease severity and mortality, noting challenges with new virus mutations and the importance of vaccine compatibility for future efficacy, but reports no new clinical results.

This review describes the roles of 5α-reductase isozymes in prostate development and pathology and reports no new clinical results.

This review discusses the role of estrogens in hair follicle cycling and the skin, highlighting the need for more research on estrogen signaling pathways and their interactions with other factors in hair biology.

This review discusses the influence of menopausal status on hair parameters in women without alopecia, finding significant differences in hair growth rate, percentage anagen, and hair diameter distributions, particularly in the frontal scalp.

This review discusses the mechanisms of skin aging, highlighting the roles of stem/progenitor cells, genetic and environmental factors, and suggests potential for cell-based therapies, but reports no new experimental findings.

In this study, BPA rapidly increased dendritic spine and synapse densities in cultured rat hippocampal neurons, with involvement of estrogen receptors and ERK1/2 and p38 pathways, but disrupted dihydrotestosterone's effects on synaptic plasticity.

This study found that older patients with Cushing's syndrome had fewer typical symptoms of hypercortisolism, more comorbidities, and were more often treated conservatively compared to younger patients.

Healthy aging can be promoted through physical activity, lifestyle changes, and certain treatments.

This review discusses the role of keratins in epithelial cell stress protection and cancer, highlighting their potential as multifunctional regulators and diagnostic markers, without presenting new research findings.

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 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 the biochemical properties and clinical significance of 5 alpha-reductase isozymes and reports no new clinical results.

This study found that using a Picosecond IR Laser (PIRL) on mouse skin led to less tissue damage and scarring compared to conventional surgical lasers and tools.

This review discusses genetic and environmental factors contributing to autoimmunity in alopecia areata and reports no new clinical findings, emphasizing the need for further study on its aetiology and pathophysiology.

This article reviews the complex pathophysiology of polycystic ovary syndrome, highlighting how genetic, hormonal, and environmental factors contribute to its diverse symptoms, and reports no new results.

This review discusses the isolation, structure, and bioactivity of lignans and neolignans from 2016 to mid-2018, reporting no new clinical results but highlighting their potential protective properties against diseases such as cancer and neurodegeneration.
