research Serum Metabolomics Study of Polycystic Ovary Syndrome Based on Liquid Chromatography–Mass Spectrometry
Women with PCOS have different levels of certain fats and proteins in their blood, which could help diagnose the condition.
research A new label-free screen for steroid 5α-reductase inhibitors using LC-MS
Researchers developed a new method to find substances in herbs that can block a specific enzyme linked to hair loss.
research Simultaneous determination of minoxidil and minoxidil sulfate by high-performance liquid chromatography with UV-detection and its applications
The study developed a method to detect minoxidil and its sulfate form, found that minoxidil sulfate is temperature-sensitive, and identified a way to potentially increase its stability for hair loss treatment.
research Picogram determination of finasteride in human plasma and semen by high-performance liquid chromatography with atmospheric-pressure chemical-ionization tandem mass spectrometry
Method detects finasteride in plasma and semen with high sensitivity and accuracy.
research Defining hyperandrogenaemia according to the free androgen index in Chinese women: a cross-sectional study
FAI values above 6.4 may suggest high androgen levels and increased metabolic risks in Chinese women of reproductive age.

A new method accurately measures nine steroid hormones in human serum with high sensitivity.
research Pharmacokinetics of a transdermal testosterone cream in healthy postmenopausal women
A 5 mg dose of transdermal testosterone cream effectively restores testosterone levels in postmenopausal women.
research Determination of Vitamin B3 Vitamer (Nicotinamide) and Vitamin B6 Vitamers in Human Hair Using LC-MS/MS
The method can measure vitamin B3 levels in human hair accurately.
research A Non-Invasive Hair Test to Determine Vitamin D3 Levels
The hair test for vitamin D could be a useful alternative to blood tests, providing a longer-term vitamin D status, but more research is needed.
research The impact of COVID-19 pandemic and lockdown on chronic stress assessed by hair cortisol analysis via LC-MS/MS
Chronic stress increased after lockdown, especially in young adults and females.
research Exploring the Impact of the Microbiome on Neuroactive Steroid Levels in Germ-Free Animals
Gut microbes significantly affect brain steroid levels.
research Evaluating the diagnostic accuracy of androgen measurement in polycystic ovary syndrome: a systematic review and diagnostic meta-analysis to inform evidence-based guidelines
Androgen measurement helps diagnose PCOS, but accuracy varies, needing standard methods.
research Experimental and computational approaches for measuring minoxidil solubility in propylene glycol + water mixtures at different temperatures
Minoxidil dissolves better in propylene glycol and water as temperature and propylene glycol amount increase.
research Effect of Testosterone Supplementation With and Without a Dual 5α-Reductase Inhibitor on Fat-Free Mass in Men With Suppressed Testosterone Production
Testosterone's muscle-building effects do not require its conversion to DHT.
research Androgen Profiling by Liquid Chromatography–Tandem Mass Spectrometry (LC-MS/MS) in Healthy Normal-Weight Ovulatory and Anovulatory Late Adolescent and Young Women
The research found that anovulatory young women have higher androgen and hormone levels than those who ovulate, suggesting immature hormonal regulation rather than a specific condition.
research Anticoagulant-free preparation of autologous platelet-rich plasma (PRP) / fluid platelet-rich fibrin (f-PRF): a pre-clinical comparative performance study
Exprecell™ is as effective as traditional methods but produces more f-PRF and is simpler to use.
research High-performance liquid chromatography–diode array and electrospray-mass spectrometry analysis of non-allowed substances in cosmetic products for preventing hair loss and other hormone-dependent skin diseases
The method effectively identifies banned substances in hair loss and skin disease cosmetics.
research Estimation of serum aldosterone, free testosterone and DHEA-S and scalp androgen and aldosterone receptors in female androgenetic alopecia. Is the mystery solved?
High aldosterone and free testosterone levels link to female hair loss; testing aldosterone may predict hypertension risk.
research Simultaneous determination of androgens and prostaglandins in human urine using ultra-high-performance liquid chromatography–tandem mass spectrometry
Researchers developed a reliable way to measure hormones in urine, showing that a baldness treatment doesn't change hormone levels.
research Development of a Liquid Chromatography/Mass Spectrometry-Based Inhibition Assay for the Screening of Steroid 5-α Reductase in Human and Fish Cell Lines
A new method was created to test the effectiveness of Dihydrotestosterone (DHT) inhibitors, like finasteride and dutasteride, in human and fish cells. The results showed fish cells are more sensitive to these treatments, and dutasteride works better than finasteride in all tested cells.
research Mesenchymal Stem Cell Secretome: Toward Cell-Free Therapeutic Strategies in Regenerative Medicine
The secretions of mesenchymal stem cells could be used for healing without using the cells themselves.
research Design and In Vitro Evaluation of Finasteride-Loaded Liquid Crystalline Nanoparticles for Topical Delivery
LCN may improve finasteride delivery for hair loss treatment.
