This study introduces a tabletop technique demonstrating that endogenous biomagnetic fields from human hair can induce red blood cells agglutination and Rouleaux formations.

This study found that testosterone, finasteride, and castration in rats decreased serum thyroxin levels, with testosterone also affecting body and prostate weights.

This study found that α-ketoglutarate protected dermal papilla cells from oxidative stress by enhancing the Nrf2 pathway and mitigating cell damage through the ERK/Nrf2 axis.

This study found that testosterone therapy improved physical performance and strength in older men with low testosterone over 36 months, whether administered alone or with finasteride.

This review explores the significant impacts of hormonal changes within normal physiological ranges and suggests examining low-dose effects from chemicals disrupting hormonal activity; it presents no new clinical results.

This study found that finasteride users had higher odds of testicular abnormalities, obesity, and other conditions, highlighting the need for confounder adjustment in studies on its association with male breast cancer.

This study found that augmenting or reducing allopregnanolone activity in the BNST affected contextual fear expression in rats, suggesting sex differences in anxiety may be linked to neuroactive steroid regulation.

This article discusses the potential effects of exogenous testosterone, highlighting that its impact on prostate cancer progression, cardiovascular health, and behavior remains uncertain and needs further investigation.

This study found that administering testosterone increased the expression of sexual behavior and elevated serum testosterone and DHT levels in female capuchin monkeys, hinting at potential insights into testosterone use and its risks in humans.

This review highlights the potential of nanotechnology for hair follicle regeneration, focusing on strategies such as hair cycle modulation, progenitor cell stimulation, and wound-induced hair neogenesis, while also discussing regulatory challenges that may affect the development of these innovative approaches.

This article discusses a report on reversible alopecia associated with fluconazole therapy and mentions other possible causes of hair loss but presents no new findings.

This study confirmed that the diffusion of cortisol from blood is a biologically endogenous source of hair cortisol, correlating significantly with salivary cortisol levels in healthy humans.

This review discusses the use of hair analysis for examining stress and reproduction hormone levels in wildlife and highlights the need for more comprehensive physiological validations across species.

The researchers reported that various environmental factors and higher testosterone levels were linked to different patterns of hair loss in women with androgenic alopecia.

In this study, testosterone and finasteride were found to increase insulin and zinc levels while decreasing chromium levels in male adult rats, suggesting potential effects on the glucose cycle.

This study found that transient non-lethal levels of endogenous ROS in cultured human hair follicles promoted entry into the growth phase by activating the hair follicle stem cell niche.

In this study, researchers developed a method to measure steroid hormones in hair and found that body hair typically contains higher levels of cortisone and testosterone compared to scalp hair, but hair pigmentation did not affect hormone concentrations significantly.

This research indicates that androgens may drive hidradenitis suppurativa in some patients, as they show higher testosterone levels compared to nonaffected controls, and testosterone-lowering medications are established treatments for milder cases.

In this study, researchers observed that obese women experienced heightened levels of endogenous intoxication shortly after undergoing a cesarean section, which may point to potential complications. Further research is needed to create effective strategies for preventing and treating post-operative complications in this population.

This case report describes an adolescent girl with polycystic ovarian syndrome and endogenously elevated androgen levels who developed a hepatic adenoma, suggesting a link between the two conditions.

This study found that testosterone therapy improved physical performance, strength, lean body mass, and serum cholesterol in older men with low testosterone levels, with or without the addition of finasteride.

This study found that environmental factors such as smoking, alcohol consumption, exercise, and testosterone levels may significantly influence various forms of hair loss in male identical twins.

This study found that exogenous zinc improved the viability of ultralong random skin flaps in Wistar rats by reducing oxidative damage and increasing protective protein levels.

In this study of hydroponically grown tomatoes, the authors reported that adding melatonin at 10-30 μmol·L-1 effectively enhanced lateral root development, root hair growth, biomass accumulation, and root activity by influencing related gene expression and hormone levels.

This review analyzed observational studies on endogenous sex steroids and CVD risk, reporting mixed findings: lower testosterone and higher estradiol levels were associated with increased CVD risk, but significant literature gaps remain.

In this study, researchers found that both direct and witnessed trauma in mice are associated with reduced levels of the neurosteroid allopregnanolone, potentially influencing PTSD outcomes, and that treatment with synthetic neurosteroids may mitigate fear responses linked to observed trauma.

This study found that metyrapone and etomidate provide dose-dependent anticonvulsant effects against seizures, with delayed effectiveness linked to increased neurosteroid levels.

In this study, researchers found that both direct and witnessed trauma in mice were linked to lower levels of the neurosteroid allopregnanolone, and that boosting neurosteroidogenesis may alleviate PTSD-like symptoms, suggesting potential treatment strategies for PTSD stemming from either trauma type.

In this study, Quercetin-loaded black seed oil nanoemulsion effectively mitigated testosterone-induced testicular oxidative stress and inflammation in rats undergoing exercise and restraint stress, with improved antioxidant levels and reduced inflammatory markers compared to other treatment groups.

This study found that metabolite levels in hair samples differ significantly by hair color and segment, leading to recommendations for best practices in hair metabolomic studies.
