In this study, hair samples from breast cancer patients showed increased β-sheet structures and lipid content, with spectral markers successfully identifying cancer in a blind test but also producing false positives.

Machine learning can use blood tests to help predict moderate-to-severe alopecia areata.

This study found that the total testosterone/dihydrotestosterone ratio is significantly higher in women with polycystic ovary syndrome and is associated with a worse metabolic profile in both PCOS and healthy women.

This study found that orlistat significantly reduced weight and total testosterone levels in Iranian women with polycystic ovary syndrome after 12 weeks of treatment.

In this case report, a male patient with hair loss showed unusually high testosterone levels without other symptoms or supplement use; follow-up testing revealed normal levels, showcasing the importance of considering testosterone-protein binding differences and using equilibrium dialysis for accurate assessment.

This study observed that "physiological" hyperandrogenism due to elevated total testosterone was associated with a 23.5% incidence of arterial hypertension, unlike hyperandrogenism due to elevated DHT levels.

This study found that patients with systemic lupus erythematosus and diffuse hair loss showed non-scarring alopecia without inflammation and a decrease in total hair follicles.

In this report, a preterm neonate was found to have total irreversible hair loss due to congenital atrichia, confirmed by a mutation in the human hairless gene on chromosome 8p22, illustrating this rare autosomal recessive disorder.

This study found that Hibiscus rosa-sinensis dried leaves extract displayed the strongest pancreatic lipase inhibitory activity among 37 tested plant extracts, showing potential as an anti-obesity agent with effects comparable to the pharmaceutical drug orlistat in reducing plasma triacylglycerol levels in rats.

This review discusses the controversial cardiovascular safety and efficacy of subcutaneous testosterone therapy in postmenopausal women, noting that its long-term use appears safe, but CV risk assessments remain disputed.

This study found that in men, elevated androgen levels can occur at any age, with older men potentially exhibiting increased total testosterone due to higher levels of SHBG, and younger men showing various clinical manifestations like acne and alopecia.

This study found that acupressure on specific points improved health-related quality of life and reduced total testosterone levels and clinical symptoms in patients with polycystic ovary syndrome compared to controls.

This study found that a low estrogen-containing oral contraceptive normalized hormone levels and improved symptoms in women with polycystic ovary disease, with minimal side effects reported.

In this study, it was found that higher test anxiety negatively correlated with lower OSCE performance among medical students at Taif Medical College, with female students experiencing a greater impact than males.

This study found that Mueller-Hinton Agar performed better than Dermasel Agar for antifungal susceptibility testing of feline dermatophytes, providing reliable susceptibility data for effective antifungal therapy.

This study found that the 4Kscore model, when adjusted for kallikrein marker changes due to finasteride use, improved the prediction of high-grade prostate cancer compared to adjusted total PSA alone in men taking 5-α-reductase inhibitors.

This study found that adding Cinnamomum zeylanicum bark extract to a powder shampoo formulation significantly improved antioxidant activity without affecting its cleansing ability, although its clinical effectiveness remains to be tested.

In a clinical observation study, researchers documented a case of total alopecia in an 11-year-old child, highlighting a potential link to genetic conditions such as autoimmune polyendocrinopathy candidiasis-ectodermal dystrophy (APECED syndrome) requiring further genetic and serological testing to verify the diagnosis.

This review discusses the importance of physical examinations in trichology, emphasizing their role in diagnosing conditions like alopecia and hair dystrophies, and reports no new clinical results.

In this study, finasteride reduced oxidative stress, apoptosis, and inflammation in liver, kidney, and testis tissues of diabetic rats while boosting antioxidants, indicating potential protective effects that require further human trials for clinical application.

This study found that while a transscrotal testosterone patch increases serum testosterone levels in hypogonadal men with AIDS and weight loss, it does not improve weight, body cell mass, or quality of life.

This study found that a 5-mg daily dose of transdermal testosterone cream in postmenopausal women restored testosterone levels to those typical of premenopausal women.
