In this study, researchers observed that a significant number of women in Eket, Nigeria, have low testosterone levels, while a subset with high free testosterone may have polycystic ovary syndrome.

This study found significantly higher levels of Toll-Like Receptor 4, interferon gamma, and interleukin-17 in Iraqi patients with alopecia areata compared to controls, suggesting these immune markers play a crucial role in the disease's development and could be targets for future treatments.

This study found that children with alopecia areata had higher levels of oxidative stress markers but showed no significant differences in depression and suicide tendencies compared to healthy peers.

This study found that patients with onychomycosis had higher serum ceruloplasmin levels than healthy controls, which were also positively correlated with both disease duration and severity.

This study found that Egyptian women with frontal fibrosing alopecia had lower serum PPARγ levels and a higher occurrence of PPARG gene polymorphism compared to healthy controls, suggesting a potential role for PPARγ in the condition's development.

This study observed that elderly women exhibited a tendency for higher personal anxiety and increased brain DC-potential indicators, with distinct energy cost patterns in different brain regions compared to elderly men.

In this study of women treated for dermatological conditions in West Midlands, England, low vitamin D levels were significantly linked to hair loss, especially in women aged 35-45, suggesting vitamin D's potential role in prevention and treatment of hair loss in this group.

This pilot study found no significant relationship between blood and hair mineral concentrations in generally healthy adults, though hair analysis may have potential for assessing long-term mineral trends.

This study found that women with polycystic ovary syndrome had significantly higher serum and intrafollicular levels of anti-Müllerian hormone compared to normovulatory women, indicating a potential marker for ovarian hyperstimulation syndrome risk.

This study suggests that in women with androgenic alopecia and men with premature balding, enhanced 5α-reductase activity and altered androgen conjugation, favoring sulfurylation, may be involved in scalp hair loss.

This study determined that the upper normal cut-off levels for free testosterone, dehydroepiandrosterone sulfate, and total testosterone among reproductive-age women in China are 26 pmol/L, 4.92 μmol/L, and 2.39 nmol/L, respectively.

This study found that injecting interferon gamma into C3H/HeJ mice did not alter the frequency or onset of alopecia areata, suggesting the protein alone does not trigger the disease.

This study emphasizes the necessity of confirming elevated testosterone levels detected by immunoassay with liquid chromatography-tandem mass spectroscopy before pursuing more complex diagnostic evaluations.

In this study, women with polycystic ovary syndrome showed significantly higher levels of DHEA, IL-6, and TNF-α compared to healthy controls, indicating a possible link between these biomarkers and PCOS.

This study found that women with idiopathic hyperandrogenemia had higher urinary Bisphenol A levels compared to healthy controls, suggesting a potential role of this chemical in the condition.

This article reviews the genetic associations between MTHFR mutations, homocysteine levels, and autoimmune diseases, without reporting new experimental results.

Finasteride can cause gum swelling and bleeding, but stopping the drug helps recovery.

In this study involving adult mice, the researchers identified that double-stranded RNA-mediated activation of toll-like receptor 3 stimulates wound-induced hair neogenesis, potentially reflecting mechanisms used in facial rejuvenation treatments.

This review discusses how sex hormone levels and local steroid synthesis influence gender differences in aging skin, reporting no new clinical results.

This study found that dermal papilla cells from balding scalp hair follicles have significantly higher levels of androgen receptors than those from non-balding follicles, supporting their in vivo androgen response.

This study suggests that cerebrospinal fluid levels of the neurosteroids allopregnanolone and pregnanolone correlate negatively with PTSD and negative mood symptoms, with potential sex-specific differences in synthesis enzyme blocks.

This systematic review suggests that current evidence does not support routinely discontinuing gender-affirming hormone treatments before surgery, especially testosterone and spironolactone, due to limited data on related perioperative risks.

This study found that women with female pattern hair loss had increased 5α-reductase isozymes and decreased aromatase mRNA levels, potentially affecting their response to treatment.

This study observed that adding simvastatin to ongoing metformin treatment reduced certain androgen levels in women with non-classic congenital adrenal hyperplasia and abnormal glucose metabolism, suggesting a potential therapeutic benefit.

This study suggests that analyzing hair samples with a liquid chromatography-mass spectrometric assay may offer a reliable method to measure average quarterly vitamin D levels, potentially complementing blood tests.

This study found that pelage abnormalities in Harlequin mutant mice are linked to severe AIF deficiency and associated with altered expression of genes related to hair structure.

This study demonstrates that genome-edited epidermal stem cells can continuously monitor blood glucose levels in vivo and potentially aid in diabetes treatment through skin somatic gene therapy.

This study found that serum GPER-1 levels were significantly higher in patients with androgenetic alopecia compared to healthy controls, suggesting a potential role in the condition's pathogenesis, independent of gender.

This study found that patients with age-related cataracts had significantly lower levels of manganese, selenium, vanadium, and zinc in their serum compared to healthy controls, with low serum selenium and zinc levels showing an independent association with an increased risk of cataracts.
