This study reports a good correlation between the curvature of human eyelashes and the displacement of the neutral axis, influenced by the non-uniform thickness of the outer cuticle layer.

This study found that Hoxc13 gene expression, influenced by melatonin, was associated with hair follicle activity in Cashmere goats, with in vitro evidence suggesting effects on genes relevant to follicle development.

This study found that among patients with systemic lupus erythematosus, the absence of skin rash and low levels of complement C3 were significant risk factors for developing lupus nephritis, with their combination demonstrating good predictive diagnostic value.

This study found that in South Asian women with PCOS, the severity of non-alcoholic fatty liver disease is strongly linked to early renal dysfunction, as indicated by increased serum creatinine and urinary albumin levels, and reduced eGFR.

This study found that among patients with seborrheic dermatitis, the "dandelion" vascular conglomerate observed through trichoscopy was correlated with Malassezia scalp colonization.

This study found no significant difference in serum prolactin levels between vitiligo patients and healthy controls, nor any significant association between prolactin gene polymorphism and vitiligo severity, except for a significant relation with BMI.

In this case report, a 64-year-old woman diagnosed with both NMOSD and SLE showed mild improvement in vision and recovered from thrombocytopenia after treatment with glucocorticoids and Rituximab, highlighting the importance of accurate diagnosis and tailored treatment for overlapping autoimmune disorders.

This study found that male pattern baldness in European males is strongly heritable and associated with genetic markers linked to earlier puberty, bone density, and pancreatic function.

This study found that selecting Angus cattle for early puberty reduced their prolactin levels, which may indicate a response to changing day length.

In this study, heritability analyses in twins and siblings revealed that genetic factors predominantly influence hair diameter and curvature, with notable sex differences in their genetic impact.

This study found a negative correlation between serum iron levels and the duration of hair loss in patients with alopecia.

This study found that patients with alopecia areata who have low vitamin D levels and high CRP levels are more likely to develop the universalis form of the condition, indicating a need for more aggressive treatment in these cases.

This study found that women with chronic diffuse hair loss had low serum ferritin levels, indicating a significant association with decreased iron stores.

In this study, a significant positive correlation between clinical hyperandrogenism and free androgen index was found in younger women with PCOS, but not in older women.

In this study, correlations between urinary and serum androgen metabolites were examined in girls aged 6-13, revealing that summed urinary metabolites strongly correspond with circulating androstenedione and testosterone levels, though individual variations depend on participant characteristics such as age and body measurements.

This study confirmed that 25(OH)D3 can be detected in hair samples from healthy young adults, but no correlation was found between hair and serum 25(OH)D3 concentrations, indicating limited potential as a standalone biomarker.

This study found a weak and negative correlation between depression and adiponectin levels in women with polycystic ovary syndrome, which was statistically significant.

In this study, ritlecitinib treatment for 12 and 24 weeks downregulated immunity-related genes and upregulated hair keratin genes in patients with alopecia areata, correlating with scalp hair regrowth response.

In this observational study of female undergraduate students, researchers found a significant correlation between the use of eyelash extensions and ocular side effects such as itching, lashes pulling out, and heavy eyelids, affecting 54% of participants during or after use.

In this study, researchers surveyed 100 women with PCOD or PCOS and found no statistical correlation between the diagnosis and common symptoms like irregular menstruation or infertility, suggesting a need for further research with larger samples.

This study found that ZP4 expression was highest among PCOS patients with regular menstrual cycles, which may be linked to mature follicle presence, but no correlation with clinical indices was observed.

This study indicates that higher thyroid-stimulating hormone levels may be linked to post-COVID-19 hair loss in women, while ferritin levels showed no significant correlation.

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.

High testosterone to epitestosterone ratio in hair could predict male-pattern baldness.

This study found that while serum prolactin levels were higher in women with hirsutism, the relationship between prolactin levels and hirsutism severity was not statistically significant.

This study observed that in 210 infertile women with PCOS, stress significantly negatively impacted quality of life, with infertility-related quality being particularly low, and noted income, BMI, acne, and hirsutism as influential factors.

In this study, analyzing over 400 million tweets revealed a broader and milder spectrum of COVID-19 symptoms than clinical research, and illustrated symptom evolution and co-occurrence throughout the pandemic.

In this study, hyperandrogenemia in young women with polycystic ovary syndrome was linked to higher blood pressure, independent of factors like age, insulin resistance, obesity, or dyslipidemia.

This study highlights that patients with pemphigus experiencing cutaneous involvement endure pruritus levels approaching those of bullous pemphigoid, impacting their quality of life alongside other autoimmune blistering diseases.

This study found a significant decline in serum zinc levels among women of African descent using hair relaxers and experiencing alopecia, with age at first exposure potentially influencing alopecia development.
