1. Effects of aqueous and hydroalcoholic extracts and ultra-highly diluted solutions of Palicourea marcgravii (Ribiaciae) in rats. / Efeitos dos extratos aquoso e hidro-alcoólico e das soluções ultradiluídas de Palicourea marcgravii (Rubiaceae) em ratos.
A Palicourea marcgravii (Pm), a planta tóxica mais importante no Brasil, é responsável por cerca da metade das mortes por intoxicação natural em bovinos no País. A intoxicação cursa com evolução superaguda e morte súbita, atribuída ao ácido monofluoroacético, substância de alta toxidez para diversos mamíferos, inclusive o homem. A terapêutic

2. The Metabolism of Organic Acids by a Marine Pennate Diatom 1
Cocconeis diminuta, a marine benthic diatom, metabolizes acetate and lactate-14C. In the light, the major product was lipid, whereas in the dark, CO2 was the major product. Analysis of proteins synthesized in the presence of acetate or lactate showed that radioactivity was incorporated predominantly into the glutamate family of amino acids and those amino ac

3. Fermentative Metabolism of Chlamydomonas reinhardii1: III. Photoassimilation of Acetate
The anaerobic photodissimilation of acetate by Chlamydomonas reinhardii F-60 adapted to a hydrogen metabolism was studied utilizing manometric and isotopic techniques. The rate of photoanaerobic (N2) acetate uptake was approximately 20 μmoles per milligram chlorophyll per hour or one-half that of the photoaerobic (air) rate. Under N2, cells produced 1.7 mol

4. The Kok Effect in Chlamydomonas reinhardi1
A Haxo-Blinks rate-measuring oxygen electrode together with a modulated light source gave an average current signal (change in net O2 exchange) and a modulated current signal (photosynthetic O2 evolution). Using this apparatus, net O2 exchange and photosynthetic O2 evolution at low intensities have been studied in the green alga, Chlamydomonas reinhardi. At
