In this animal study, researchers found that cedrol, a constituent from Platycladus orientalis, significantly promoted hair growth in a dose-dependent manner in female C57BL/6 mice, surpassing results from blank control and 2% minoxidil groups over 21 days.

In this study, CD4+CD25+FoxP3+ Regulatory T cells were found to reduce TGF-b1 induced lung fibrosis and fibrocyte accumulation in mice, partly by suppressing fibroblast growth factor 9.

This study reported that the aqueous ethanol extract of Lygodii Spora demonstrated in vitro testosterone 5alpha-reductase inhibition and in vivo anti-androgenic activity, potentially due to oleic, linoleic, and palmitic acids.

This study concluded that five-alpha-reductase inhibitors may reduce prostate cancer risk but could increase the risk of high-grade prostate cancer in men regularly screened for the disease.

In this study, experimentally induced weight loss in merino sheep led to a decrease in wool fiber diameter and increased expression of certain high sulfur and glycine-tyrosine proteins, potentially impacting wool quality and industry preferences.

This review found evidence supporting the effectiveness and safety of topical minoxidil for treating female pattern hair loss, though many included studies were at high risk of bias.

These drugs raise prostaglandin-like material in dog blood, possibly causing blood vessel widening.

This review discusses azelaic acid's mechanisms and uses in dermatology, noting its effectiveness in treating conditions like rosacea, acne, and melasma, but reports no new clinical results.

A fungal infection can look like a different scalp condition in teens, leading to wrong treatment until proper tests are done.

In this study, rice bran supercritical CO2 extract demonstrated potential to promote hair growth in mice, increasing hair follicles and growth factor expression, similarly to 3% minoxidil.

This review reports that 100 mg/day spironolactone improved hair growth more than placebo and was more effective in reducing hair growth than finasteride and low-dose cyproterone acetate, but its effectiveness for acne remains unclear due to small sample sizes.

This review discusses the complexity of neuroactive steroid therapies for neuroprotection and reports no new clinical findings, suggesting potential unexpected effects in the brain compared to systemic levels.

In this study, patients with seasonal affective disorder were found to have increased functional connectivity in certain brain networks and higher low-frequency fluctuations compared to healthy controls, which aligns with their attentional and psychomotor symptoms.

In this study, 13-cis-5S*,8S*-epidioxy-5,8-dihydroretinoic acid was found to be significantly more cytotoxic to cancer cell lines than other retinoic acid analogs evaluated.

This review discusses recent advances in understanding the Eda pathway's role in developmental biology, and highlights ongoing trials and areas for further research, including Eda's potential involvement in cell processes and disease.

This study found that combining fractional erbium-glass laser therapy with topical minoxidil significantly improved hair density and diameter in men with androgenetic alopecia compared to using minoxidil alone over a 24-week period, with no serious adverse events reported.

This review discusses the development of an algorithmic guideline for treating androgenetic alopecia in Asian patients, using the BASP classification to address limitations of previous guidelines, and reports no clinical results.

In this study, mannosylerythritol lipids from soybean oil notably increased fibroblast and papilla cell viability, suggesting potential as a hair growth agent.

This study found that minoxidil nanoparticles increased drug delivery to hair follicles and improved hair growth more effectively in mice than conventional minoxidil formulations.

This review assessed evidence on laser therapies for alopecia areata, reporting that the 308-nm excimer laser showed hair regrowth in several studies, while more research is needed for other laser types.

This article reviews age-related changes in facial structure at a cellular level and summarizes potential solutions for rejuvenation surgery, but reports no new clinical results.

This study found that Dutasteride, a 5α-reductase inhibitor, demonstrated neuroprotective effects by preventing the MPTP-induced decline of dopaminergic markers in a Parkinson's disease mouse model.

This review discusses androgen manipulation strategies for conditions like benign prostatic hyperplasia and prostatic carcinoma but reports no new clinical results.

Finasteride affects prostate weights and pituitary activity differently with age.

In this randomized clinical trial, the authors reported that adipose-derived stem cell constituent extract topical solution increased hair density and thickness in patients with androgenetic alopecia over 16 weeks compared to placebo.

This literature review reported that fractional lasers, like the 1550-nm nonablative erbium-glass laser, may enhance hair regrowth by stimulating a wound healing process, but more randomized controlled trials are needed to confirm their effectiveness and optimize treatment parameters.

This study found that Cacumen platycladi extract significantly promoted hair growth and reduced dihydrotestosterone levels by inhibiting 5α-reductase activity in an androgen-sensitive mouse model.

This study found that polymeric nanoparticles retained more minoxidil and facilitated superior drug permeation compared to lipid nanoparticles, although premature drug release affected formulation performance.

This study concludes that rhesus macaques are a suitable model for testing the pharmacological properties of finasteride and other 5aR inhibitors, due to their biochemical similarity to humans.

This review found that oral methotrexate plus oral prednisone may improve disease activity or damage in juvenile active morphea compared to placebo plus prednisone, but adverse events may slightly increase.
