Pyruvic acid is one of the most reactive substances among those of importance in cellular metabolism. When carbohydrate is split during fermentation, pyruvic acid is the main end-product of the resulting series of phosphorylated oxidation-reductions. It thus becomes the immediate source for the formation of both lactic acid and alcohol. Pyruvic acid is decarboxylated by yeast; it may react with...

Goniothalamus spp. are widely distributed is the island of Borneo. About 40 species of Goniothalamus have been recorded in Borneo. Goniothalamus spp. are widely used in traditional medicinal practices in Borneo especially in treating diarrhea, fever, skin diseases, antidotes and most commonly used as postparturation aids and as abortifacient. Some of the species are also being used as natural i...

The synthesis of a proline-rich cyclic heptapeptide, fanlizhicyclopeptide A (8), previouslyisolated from the fruits of Annona squamosa (sugar-apples), is described via coupling oftetrapeptide l-prolyl-l-tyrosyl-l-leucyl-l-proline methyl ester with tripeptide Boc-glycyl-lvalyl-l-proline followed by cyclization of the linear fragment having seven amino acid units.Structure of the synthesized cycl...

We have assembled this mini-monograph on adult lead exposure to provide guidance to clinicians and public health professionals, to summarize recent thinking on lead biomarkers and their relevance to epidemiologic research, and to review two key lead-related outcomes, namely, cardiovascular and cognitive. The lead standards of the U.S. Occupational Safety and Health Administration are woefully o...
