research ς1Receptor-Related Neuroactive Steroids Modulate Cocaine-Induced Reward
Neuroactive steroids affect cocaine's rewarding effects through the ς1 receptor.
research Ozone interactions with human hair: Ozone uptake rates and product formation
Ozone reacts more with unwashed hair, producing compounds due to scalp oils, which could lower ozone exposure but increase exposure to reaction products.
research Transfollicular Drug Delivery: Penetration of Drugs Through Human Scalp Skin and Comparison of Penetration Between Scalp and Abdominal Skins In Vitro
Drugs penetrate scalp skin better than abdominal skin, with scalp hair follicles aiding in higher drug delivery.
research Liver transplantation for propionic acidemia in children
Liver transplantation is a viable option for children with propionic acidemia, improving quality of life and diet, but does not remove all risks and long-term brain outcomes are uncertain.
research BIOTIN-RESPONSIVE ALOPECIA AND DEVELOPMENTAL REGRESSION
Biotin treatment can significantly improve hair loss and motor functions in certain metabolic disorders.
research Potential adverse effects of long-term testosterone therapy
Long-term testosterone therapy can cause hormone suppression, affect prostate and heart health, and alter physical characteristics, but does not increase prostate cancer risk and needs more research for full risk assessment.
research Oestrogen functions in skin and skin appendages
