Twelve long-distance runners were evaluated by physical examination, electrocardiogram, vectorcardiogram, chest x-ray film, and echocardiogram; and the results were compared to the findings in 12 normal control subjects. The athletes showed a significantly higher frequency of gallop rhythms with a third or fourth heart sound. Fiectrocardiographic and vectorcardiographic abnormalities consisting...

Katz 's new clothes Katz's new view about language and linguistics comes in two parts: platonism and nonreductionism. Those of us who have been skeptical about the empirical basis for claims that have arisen from within linguistics will welcome Katz's defection to our side in respect of platonism, but we will be dismayed by his refusal to adopt the rest of our methodology concerning reductionis...

Toxoplasma gondii is a widely distributed protozoan pathogen that causes devastating ocular and central nervous system disease. We show that the endochin-like quinolone (ELQ) class of compounds contains extremely potent inhibitors of T. gondii growth in vitro and is effective against acute and latent toxoplasmosis in mice. We screened 50 ELQs against T. gondii and selected two lead compounds, E...
