The virus linked to a rare disease was found in a patient's blood and urine before skin symptoms appeared.
research 5α-Reductase Inhibitors: Evaluation of Their Potential Confounding Effect on GC-C-IRMS Doping Analysis
5α-reductase inhibitors can interfere with doping tests by masking banned substances.
research Felinine Excretion in Domestic Cat Breeds: A Preliminary Investigation
Shorthaired and hairless cat breeds excrete more felinine than longhaired breeds.
research Relationship Between Contact Time of Applied Dose and Percutaneous Absorption of Minoxidil From a Topical Solution
Longer contact time increases minoxidil absorption, but doesn't affect metabolism.
research Glycol Ethers and Neurodevelopment: Investigating the Impact of Prenatal Exposures
Exposure to certain glycol ethers during pregnancy may be linked to lower verbal comprehension in children.
research Testosterone and Doping Control
The document concludes that better biomarkers are needed to detect long-term oral testosterone use in athletes.
research Time Lags Between Various Maturity Measures and Spermarche
Certain maturity signs appear before and after the first release of sperm in boys.
