In this study, finasteride dose-dependently inhibited stress-induced increases in allopregnanolone in rats, while enhancing 20alpha-reduction of progesterone without affecting 3alpha-dihydroprogesterone or 11-deoxycorticosterone levels.

This study used proteomics to identify various proteins in human hair, which may help develop novel biomarkers for hair health, disease, and aging.

Artificially inducing hair regrowth in mice can change the normal pattern and timing of hair growth, with minimal color differences between old and new fur.

This study found that while hair follicles can be viably maintained in vitro for 7 days, their morphology suggests a shift to the resting phase, likely due to isolation.

In this animal study, rats given high doses of ethynylestradiol showed dose-related estrogenic effects, delayed tumor onset in females, and no overall increase in tumor incidence compared to controls.

This study suggests that genetic factors significantly influence adrenal androgen levels and the progression of puberty, with adrenal cortex maturation appearing independent of the hypothalamic-pituitary-gonadal axis.

Androgens don't directly affect hair cell growth or protein production.

This study found that feeding norethindrone acetate to albino rats over two years caused various dose-related health effects, such as growth retardation and liver changes, but did not increase overall tumor incidence.

Detecting steroid esters in cattle hair is inconsistent and influenced by sampling factors.

This study reported that administering finasteride reduced levels of certain neuroactive androgens in rat brains, suggesting peripheral origin for most 3α,5α-Adiol and brain synthesis for 3α,5α-A.

This study found that experimentally induced calcification in rat skin led to rapid and localized mineralization in hair follicles, progressing to more extensive calcification with prior hypercalcemic treatment.

This study observed that radioactive sulphur appeared in rat and mouse hair follicles more quickly than in lambs, possibly linked to faster hair growth rates in the rodents.

This research observed that while organic farming systems in Southern Norway showed decreased phosphorus over time and variable nitrogen retention, the mulching of plant material could enhance vegetable yields, suggesting a need for innovative nutrient management strategies in organic farming.

This study found that stilbamidine and hydroxystilbamidine can inhibit the release of specific enzymes from lysosomes and mitochondria in rabbit liver at certain concentrations, with effects similar to cortisol and chloroquine.

Different hair types from various ethnic groups affect hair shine due to characteristics like thickness and shape.

This study found that the 16th-century mummified hair from a female mummy in Paju was remarkably well-preserved, with the hair's ultrastructural features maintained likely due to a calcium-rich surface coat.

In this study, the bark of Spondias mombin showed potential anti-tumor effects in rats with induced cancer, reducing symptoms like hair loss and low food intake, but tachycardia was noted as a possible side effect.

Microscopic hair features can identify different Cauda Cervi species.

This study found that an adult female farm-raised blue fox exhibited an abnormal hair growth cycle and seasonal estradiol variation, with a delayed winter coat cycle resulting in spring shedding.

This study found that methyl nonanoate and methyl caprate significantly enhanced the skin penetration of minoxidil compared to solutions with other common enhancers like Azone, DMSO, or DEET.

In this study, epidermal growth factor expression significantly correlated with the development of secondary hair follicles in Jining Gray goats until two months of age.

This study provides detailed macro and microscopical observations of Tridax procumbens Linn. leaf, which could aid in its identification.

This study found that Sophora flavescens extract promoted hair growth in mice by advancing the hair cycle and may inhibit acne-causing bacteria, though it did not affect in vitro hair follicle cell growth.

This study found that treating permed hair with diethylene glycol monoethylether significantly reduced the formation of split ends, making it similar to untreated normal hair in terms of split ends generation.

This report describes four cases of monilethrix in children and concludes that periodic inhibition of keratin synthesis, not a metabolic defect, may explain the hair abnormality.
