This study suggests that the ADIPOQ gene polymorphism may influence the risk of alopecia areata in Egyptians, with adiponectin levels potentially serving as a marker for hair loss severity.

This study found that Syzygium aromaticum oil may improve the anagen/telogen ratio in testosterone-induced alopecia in mice, indicating potential as an alternative treatment to minoxidil for androgenic alopecia.

In this study, male Wistar rats with obesity showed reduced depressive-like behaviors, brain inflammation, and oxidative stress after long-term finasteride treatment, suggesting potential benefits of finasteride in obese conditions, while lean rats experienced adverse effects including metabolic disturbances and depressive-like behaviors.

In this rodent study, researchers found that the drug finasteride may reduce anxiety and depression-like behaviors in a model of aging, despite inducing metabolic disturbances and depressive-like behaviors in young rats, suggesting potential considerations for its use in elderly populations.

In this study, chronic exposure to finasteride induced metabolic disturbances and depression-like behaviors in young male rats, similar to those caused by obesity, but did not worsen anxiety or depression in obese rats.

This review summarizes recent findings on how the dysregulated PI3K/Akt/mTOR pathway contributes to immune-mediated inflammatory skin disorders and discusses the potential of natural products, synthetic compounds, and biologic agents in their treatment. However, it emphasizes the need for further research to develop effective therapies.

The researchers reported a high incidence of hyperuricemia in women with PCOS, with positive correlations to testosterone, SHBG, HOMA-IR, and LDL levels, but negative correlations to HbA1C, FPG, and FSI.

In this review, the authors emphasize the importance of understanding drug chemical structures to help general physicians better manage and treat acne, although no specific results are reported.

In this study, data from multiple sources found that Baricitinib significantly promoted hair regrowth and improved patient-reported outcomes in those with severe alopecia, with minimal side effects, over a 36-week period.

This study reports a case where a patient with rheumatoid arthritis and alopecia areata saw significant improvement in both conditions after switching to daily upadacitinib treatment, specifically achieving complete hair regrowth within six months.

This review discusses the molecular mechanisms of androgens and androgen receptors in skin disorders, particularly androgenetic alopecia, and reports no new clinical results; it highlights potential areas for future treatment development.

This study found that androgens inhibit hair follicle stem cell differentiation by disrupting the Wnt signalling pathway in dermal papilla cells, but Wnt activation can restore differentiation.

This review discusses current experimental approaches for regenerating human hair follicles using tissue engineering and isolated cells, but reports no successful strategies with adult cells yet found.

This study found that composite skin constructs containing dermal papilla cells promoted better skin healing and hair regeneration in nude mice, highlighting their role in tissue-engineered skin for severe injuries.

This study found that DKK1 and WNT10b are paracrine factors that modulate hair follicle stem cell differentiation inhibition, contributing to androgenetic alopecia by affecting Wnt signaling in androgen-sensitive dermal papilla cells after dihydrotestosterone stimulation.

Targeting androgen receptors with antiandrogen oligonucleotides could effectively treat hair loss.

This study found that androgens downregulate BMP2 in dermal papilla cells, inhibiting hair follicle stem cell differentiation, while BMP2 addition may restore hair lineage differentiation through the Wnt/β-catenin pathway.

This research developed a zinc-doped nanocomposite using biodegradable materials, observing effective bone targeting and regeneration capabilities in vivo, with no observed cytotoxicity in the MG63 cell line, potentially due to blocking Farnesyl Diphosphate Synthetase to inhibit osteoclastic activity and promote osteogenesis.

This study found that both CO2 laser combined with topical methotrexate and calcipotriol plus betamethasone treatments improved nail psoriasis similarly, but some symptoms showed no improvement.

Minoxidil helps hair growth by improving blood vessel function.

Androgens reduce hair growth by affecting cell differentiation and blood vessel formation.

This study found that BMPs can counteract the inhibitory effects of androgens on hair follicle stem cell differentiation, highlighting their critical role in the pathway dysregulation seen in androgenetic alopecia.

This study found that in laboratory settings, dermal papilla cells cultured as spheroids showed significantly higher hair inductive potential and angiogenic factor expression compared to monolayer cultures.

This study found that dihydrotestosterone alters the balance of Wnt pathway regulators in dermal papilla cells, hindering hair follicle stem cell differentiation and contributing to hair follicle miniaturization.

This study concluded that bone morphogenetic proteins are crucial for hair follicle stem cell differentiation and that their downregulation by androgens may contribute to the development of androgenetic alopecia.

This study found that Bone morphogenetic proteins (BMPs) play a crucial role in dermal papilla cells' ability to induce hair follicle stem cell differentiation, and that androgens may impair this process by downregulating BMPs.

This study reports that six shampoo brands in Saudi Arabia generally comply with the national specifications, demonstrating good physicochemical properties such as foam stability and pH levels.

This study found that presynaptic inhibition of Aαβ cutaneous primary afferents in cats is mostly mediated by GABAergic interneurons that also contain glycine.

This study reports that CD200R expression is significantly reduced in a mouse model of scarring alopecia, suggesting a potential role for this pathway in immune regulation and hair follicle protection.
