L-arginine has been studied in combination with the standard of care, oral type-5 phosphodiesterase (PDE-5) inhibitors, for erectile dysfunction. The efficacy of a combination of L-arginine, nicotinic acid, and propionyl-L-carnitine (PLC) with and without the PDE-5 inhibitor, vardenafil, was assessed in men with diabetes and erectile dysfunction.
Oroville Dam. Once called the ninth wonder of the world, the Oroville Dam is the tallest dam in the United States, besting Hoover Dam by more than 40 feet. Built between 1962 and 1968, the Oroville Dam is comprised of more than 85 million cubic yards of earth. Tours are available by appointment only.
Managers at the nation's tallest dam made a critical mistake by allowing the lake behind it reach its highest level ever. That's according to Bill Connolly, a Butte County supervisor in California whose district includes Oroville Dam. The Associated Press reported Wednesday that dam managers obtained an uncommon exemption from the Army Corps of Engineers to bypass a rule that would have required them to release huge amounts of water from the rapidly filling dam.
