This study found differences in urinary androgen and estrogen concentrations between male pattern baldness patients treated with finasteride and healthy controls, suggesting potential biomarkers for post-finasteride syndrome.

This study developed a precise and reliable UV spectrophotometric method for determining finasteride concentration in bulk and tablets, demonstrating strong linearity and accuracy.

This study found that a herbal formulation optimized with specific concentrations of plant extracts showed promising antifungal activity against Malassezia furfur.

This study found that hair follicle cells' growth in vitro is influenced by the concentration of androgens and antiandrogens, with papilla cells and outer root sheath keratinocytes showing distinct sensitivity.

This study found that spironolactone reduced fish fecundity and caused masculinization of females at certain concentrations, while having no effect on Daphnia magna reproduction, underscoring concerns for environmental exposure to vertebrates.

This study found that nonobese women with idiopathic hirsutism had significantly lower nitrite/nitrate concentrations and higher fibrinogen levels compared to controls, but similar levels to women with PCOS.

This study found that nonobese women with idiopathic hirsutism exhibited lower nitrite/nitrate concentrations and higher fibrinogen levels compared to control subjects, but these were similar to levels in women with polycystic ovary syndrome.

This review discusses the pharmacological properties and clinical applications of cyproterone acetate and similar antiandrogens, noting previous failures in local applications due to concentration limitations; it reports no new empirical results.

Minoxidil absorbs poorly through skin, with low risk of side effects at 1-2% concentration.

This study found that multiple ion channel modulators, used here at clinical concentrations, increased intracellular calcium release in prostate and breast cancer cell lines.

This study developed a reliable RP-HPLC-DAD method, finding that amino acid concentrations in bleached hair decrease with higher hydrogen peroxide levels, notably affecting cystine.

This study reported that phytosome formulations of citrus flavonoids naringenin and naringin showed significantly increased oral bioavailability and plasma drug concentration in rabbits, suggesting that phytosome technology effectively addresses the pharmacokinetic limitations of these compounds.

This study observed that applying a cream containing secretome from Bovine Umbilical Vein Endothelial Cells promoted healing and regeneration in burn wounds in rats, particularly at a 15% concentration.

This study found that finasteride and melengestrol acetate exhibit varying levels of toxicity to freshwater mussels, amphipods, and mayflies, but current environmental concentrations suggest minimal direct effects on these aquatic invertebrates.

This review discusses various chromatographic methods for analyzing finasteride in biological fluids and provides no clinical findings, focusing on detection techniques for different concentration levels.

This preclinical study found that Mesenchymal Stem Cell-derived Conditioned Media formulations were safe and effective in rat and mouse models for treating chemotherapy- and radiation-induced oral mucositis, demonstrating improved tissue regeneration and healing, most notably at higher concentrations.

This phase 1 study reported that after administering supratherapeutic doses of cortexolone 17α‐propionate, a topical antiandrogen intended for hair loss treatment, there was no effect on the QTc interval, indicating no measurable cardiac safety concerns in the concentration range tested.

This study suggests that decreased SHBG levels and increased FAI, free testosterone, and DHEAS concentrations are effective in diagnosing PCOS in epidemiological studies of women of reproductive age.

In this study, a novel electrochemical sensor using a molecularly imprinted polymer was developed for the sensitive detection of minoxidil, successfully measuring its concentration in real samples.

This study found that cotreatment with graphene oxide and indole-3-acetic acid significantly inhibited root development in Brassica napus, with the inhibition increasing as indole-3-acetic acid concentration rose.

This review reports that sonidegib and vismodegib, two Hedgehog inhibitors used for treating advanced basal cell carcinoma, have similar efficacy and safety profiles, but differ in pharmacokinetics, with sonidegib achieving peak concentration more rapidly and reaching steady state later than vismodegib.

This study found that minoxidil absorption through the skin increased with longer contact times, reaching over 75% of the maximum absorption within four hours.

This study found that hair absorbs significant amounts of NaBr from solution, with absorption increasing linearly with solution concentration and additional effects noted with acidic or basic solutions.

This study found that hair treatment materials commonly used in Iraq and from international sources had radon, radium, and uranium concentration levels below international safety limits, suggesting they are safe for use.

This study found petroleum ether to be more effective than methanol at extracting β-sitosterol from Eclipta alba, with higher concentrations detected using HPTLC and HPLC methods. The extracted materials contained metals within safety limits.

This study reported that pentoxifylline-loaded liposomes, optimized using a statistical design method, achieved a maximum encapsulation efficiency of 84.23% and a controlled 72-hour drug release, potentially improving therapeutic delivery of the drug with limited bioavailability.

In this study, a 15% ethanol extract of Moringa oleifera leaves was most effective in improving wound healing, scab formation, and hair growth in hyperglycemic rats, compared to povidone iodine and lower extract concentrations.

This study reports that in a rat model of myocardial infarction, Zn-Cu ion sequential therapy improved cardiac function and cardiomyocyte metabolic activity by precisely regulating ion concentrations and maintaining elevated levels of the Per2 protein, important for cellular repair.

This study found that Eclipta alba extracts exhibit 5α-reductase inhibitory activity, with the methanolic extract showing a higher concentration of β-sitosterol compared to petroleum ether extract, indicating potential for treating androgenic conditions like male pattern baldness.

In this study, nanoemulsion formulations were found to significantly enhance the skin retention of the antiseptic agent triclosan, with the optimal mixture being a low surfactant concentration, as demonstrated through quantitative and qualitative analysis using tape-stripping and micro CT scans.
