research Recent Advances in Neuropeptide-Related Omics and Gene Editing: Spotlight on NPY and Somatostatin and Their Roles in Growth and Food Intake of Fish
New tools show that in fish, NPY increases feeding and somatostatin decreases it.
research The Roles of Non-Coding RNA in the Development and Regeneration of Hair Follicles: Current Status and Further Perspectives
Non-coding RNAs are important for hair growth and could lead to new hair loss treatments, but more research is needed.
research Gender Differences in Production and Circulating Levels of Sex Hormones and Their Impact on Aging Skin
Men and women experience skin aging differently due to changes in sex hormone levels with age.
research Hedonic Sensitivity to Natural Rewards Is Affected by Prenatal Stress in a Sex-Dependent Manner
Prenatal stress changes how male and female rats enjoy rewards differently, linked to sex hormones.
research Changes in Androgen Levels in Menopausal Women
Menopausal women have higher androgen levels, which can cause symptoms like facial hair growth and low sexual desire.
research Testosterone Enhances Expression and Functional Activity of Epithelial Sodium Channel, Cystic Fibrosis Transmembrane Regulator, and Sodium Hydrogen Exchanger in Vas Deferens of Sex-Steroid Deficient Male Rats
Testosterone changes how certain channels work in male rat reproductive tracts, affecting fertility-related fluid balance.
research Cross-Sex Hormone Therapy in Australia: The Prescription Patterns of Clinicians Experienced in Adult Transgender Healthcare
Australian doctors experienced in adult transgender healthcare mostly prescribe intramuscular testosterone and oral estradiol, recommend mental health assessments before hormone therapy, and support improved training and guidelines.
research Frontal Fibrosing Alopecia: Just Lichen Planopilaris?
Frontal Fibrosing Alopecia may be a complex condition linked to hormonal changes in women, not just a form of Lichen Planopilaris.
