This study determined that a total testosterone concentration of ≥5.1 nmol/L identified androgen-producing tumors in women with severe hyperandrogenemia, while a lower threshold of ≥2.2 nmol/L was found for diagnosing pathologic hyperandrogenism in postmenopausal women.

This study developed and validated a method using hair samples to simultaneously detect bisphenols and parabens, enabling the quantification of these endocrine disruptors in a hospital population’s hair.

This study found that a modest increase in dietary zinc over six months resulted in a detectable increase in sulfur and zinc counts in individual hairs, suggesting a non-invasive method to monitor zinc intake effects.

This study developed a new method using liquid chromatography-tandem mass spectrometry to measure multiple steroid hormones in hair, requiring significantly fewer strands than previous methods, with high accuracy and precision.

Coconut oil can penetrate hair better than mineral oil, potentially protecting against damage.

This study on Qatari patients with Woodhouse-Sakati syndrome highlights the high incidence and diverse clinical presentation due to a specific genetic variant, emphasizing early diagnosis for effective management.

This study used a newly validated method to find that one-year finasteride treatment resulted in no significant differences in urinary androgen and prostaglandin levels between male pattern baldness patients and normal controls.

This study reports a novel LSS gene mutation in an Egyptian family with alopecia intellectual disability syndrome 4, expanding the known clinical and genetic features of the condition.

This review outlines the urgent need for effective therapeutic interventions against coronaviruses, as current vaccines are challenged by virus mutations, and emphasizes developing safe, affordable, and broad-spectrum antivirals for both human and porcine coronaviruses.

This study validated a highly selective and fast LC–MS/MS method for accurately measuring levels of tadalafil and finasteride in human plasma, adhering to international bioanalytical guidelines.

This study assessed whether the elemental composition of human hair could serve as a marker for kidney stones, cholelithiasis, hypertension, and diabetes, but it reports only variations in element content along hair regions.

The woman likely died from acute arsenic poisoning, not chronic exposure.

This study adds evidence suggesting a genetic component to frontal fibrosing alopecia, with daughters experiencing an earlier onset than their mothers, although the clinical pattern remains similar to non-familial cases.

This review addresses clinical findings in parathyroid disease and discusses the metabolism of calcium, phosphorus, vitamin D, and parathyroid hormone, reporting no new results.

Inositol helped cure hair loss around rats' eyes and improved their growth.

This study developed and validated a highly sensitive LC-MS/MS method for detecting multiple steroid hormones in urine and serum/plasma, demonstrating its potential for use in large-scale biomonitoring studies.

This study describes a new method using high-resolution mass spectrometry for analyzing multiple steroids in human scalp hair, with newborn hair showing the highest steroid concentrations among examined age groups.

This study identified the major component of katuk leaf water extract as an alkaloid compound with a molecular mass of 406.3131 m/z, named (S, S)-5,5′-amino-4,4′-dihexyl-propyldihydropyrazol-3,3′-one.

This study described cases of alopecia areata occurring after COVID-19 vaccination and highlights management using both topical and systemic therapies.

This study observed that multiple familial trichoepitheliomas commonly presented with a cribriform histopathological tumor pattern, differentiating them from solitary trichoepitheliomas.

This study developed and validated a highly sensitive method using ultrahigh-performance liquid chromatography with tandem mass spectrometry for accurately analyzing nine neuroactive steroids in human serum, which could enhance understanding of disease pathophysiology and support new biomarker and therapeutic discovery.

In this study, researchers reported that women with polycystic ovary syndrome in a German-speaking population had higher probabilities of depression, anxiety, sleep disorders, and obstructive sleep apnea, all associated with BMI and insulin resistance.

This study successfully established and validated a method using LC-MS/MS to measure multiple androgens in plasma, finding that individuals with acne had higher levels of certain androgens compared to those with obesity.

This study found that higher levels of dihydrotestosterone in the parietal region of the scalp may correlate with the clinical presentation of androgenetic alopecia.

This study found that patients with androgenetic alopecia had deficiencies in certain trace elements and vitamins, which were linked to distinct patterns of hair loss connected to androgen levels.

This study found that the proposed LC-MS/MS method accurately quantified the drug content in split tablets of finasteride and terbinafine, revealing significant variability and suggesting that non-scored tablets should not be split.

This study reported the development of a workflow that combines SIMS and X-ray elemental mapping techniques for multimodal imaging at the single cell level, successfully applied to visualize elements, metals, and lipids in porcine skin without loss or delocalization.

This study found that ATR-FTIR spectroscopy combined with machine learning effectively differentiated alopecia areata patients from healthy controls with an AUC of 0.85, and also showed promise in predicting treatment response, particularly through alterations in the Amide I band.

This study used enhanced Raman spectroscopy to successfully detect ultra-low levels of free testosterone in women with PCOS, suggesting a potential low-cost method for early diagnosis.

This cross-sectional study examined gender-affirming surgeries in Canada, finding significant variation in provincial insurance coverage, with Prince Edward Island covering the most procedures and Nunavut the least, while noting a general lack of in-province procedures in the territories.
