This study found that the severity of female pattern hair loss in premenopausal women was associated with clinical signs of hyperandrogenism, such as hirsutism and acne, but not with biochemical parameters.

This study found that Arabidopsis mutants with disrupted auxin conversion pathways displayed low auxin phenotypes and increased biosynthetic gene expression, suggesting a feedback mechanism maintains auxin homeostasis.

This study found that cadmium levels were significantly higher in women with chronic telogen effluvium compared to healthy controls, suggesting cadmium toxicity might contribute to this hair shedding condition.

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.

In this study involving rats with letrozole-induced polycystic ovary syndrome, Agaricus subrufescens significantly reduced blood glucose, total cholesterol, testosterone levels, and renal markers, suggesting its potential protective effects on both metabolic and reproductive parameters.

This study in neonatal rats found that inhibiting neurosteroid synthesis with finasteride unexpectedly reduced the severity and duration of neonatal seizures following birth asphyxia, maintained cognitive functions, but increased anxiety-like behaviors, highlighting a complex role of neurosteroids in hypoxic-ischemic encephalopathy outcomes.

This study found that early biochemical screening and molecular confirmation are crucial for distinguishing profound from partial biotinidase deficiency, which supports timely treatment and management in symptomatic children.

This study reports the development of a novel protocol to purify human TRPV3 ion channels, revealing functional properties and differences in ligand interactions, enabling further structural and functional research.

This study observed that extracellular ATP (eATP) levels outside Arabidopsis root cells vary inversely with the expression of AtAPY1 and AtAPY2 apyrases, suggesting these enzymes regulate eATP concentrations crucial for root growth.

This study found that S. scabiei infestation in rabbits leads to epidermal thickening possibly due to apoptosis-related proliferation and keratinization of the skin.

This study found that female pattern hair loss in Saudi women was associated with lower hematological parameters and serum ferritin levels, suggesting iron deficiency may contribute to the disease.

This study found that women with polycystic ovary syndrome had significantly higher levels of the protein fetuin-A compared to healthy controls.

This study found that women experiencing hair loss after recovering from COVID-19 had significantly lower Vitamin D and ferritin levels and higher testosterone and triglyceride levels compared to those without hair loss, indicating a potential link between these factors and the condition.

This study found that total testosterone, DHEA-S, and free androgen index may help distinguish menstrual irregularities from increased risk of polycystic ovary syndrome in adolescents.

This study found no association between serum zinc levels and alopecia areata severity in patients.

This study found that in males with mild COVID-19, treatment with dutasteride, along with standard therapy, may reduce viral shedding and inflammation compared to placebo.

This review synthesizes current knowledge on choriogenesis, the final stage of oogenesis in insects, by exploring the role of follicle cells, regulatory mechanisms of gene expression, and the biochemical makeup of the eggshell, while also highlighting structural diversity and adaptations across insect species.

In this study, researchers observed that even a single session of hair dyeing can damage hair fibers, with significant worsening of mechanical properties and protein composition after three or more consecutive treatments, emphasizing the need to consider the cumulative impacts of dyeing on hair health.

This study found that iron therapy improved nonhematological symptoms and cognitive function in women with iron deficiency anemia, highlighting the need for attention to these symptoms in improving quality of life.

This review discusses the roles of metabolism, reactive oxygen species, intracellular pH, and cell morphology in influencing cell fate decisions during stem cell differentiation but reports no new experimental results.

In this study, researchers found that glycan profiles in epidermal stem cells differed between young and old mice, suggesting these changes may serve as molecular markers for aging.

This article reviews various methods and introduces new imaging technologies to assess the effects of hair shaping treatments on hair chemistry and structural integrity, without reporting clinical results.

This review discusses the mechanisms by which laser treatment affects hair structures and growth, highlighting its potential for permanent hair reduction and associated skin damage, but reports no new experimental results.

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.

In this animal study, topical VEGF gel increased hair growth and thickness in Mesocricetus auratus, although it was not completely inert, highlighting the need for further toxicity confirmation.

This review discusses how using hydrogels as a three-dimensional culture platform for mesenchymal stem cells might affect the production of extracellular vesicles, highlighting challenges in standardization and opportunities to boost EV yield via combined hydrogels and bioreactor methods.

This study aims to compare the safety and effectiveness of bariatric surgery versus medical care on ovulation rates in women with PCOS and obesity, as current observational data suggests surgery may improve fertility prospects, but no randomized trial has yet confirmed this effect.

This study reports that subcutaneous testosterone pellets in peri- and postmenopausal women provided sustained hormone release and potential benefits for sexual function, but raised concerns about safety, variability, and dosing inconsistencies.

This study found that serum prolactin levels were significantly higher in patients with psoriasis, alopecia areata, and vitiligo compared to healthy controls, and prolactin levels were also correlated with disease severity in psoriasis and alopecia areata patients.
