For some years now, urinary amino acid screening for inborn errors of metabolism has been routine in many institutions. In the early 1960’s, Cox and White (1) as well as Barness et a!. (2) showed the importance of measuring methylmalonate excretion in the urine of patients suffering from pernicious anemia. Since that time, detection of non-nitrogenous organic acids has taken on an importance si...

Treatment of hemoglobin with H&S and 02 gives rise to the formation of a green pigment, sulfhemoglobin. In contradistinction to the transformation of hemoglobin into HbOz, HbCO, Meth-Hb, and other hemoglobin derivatives the transformation into sulfhemoglobin is not reversible. The nature of this reaction is as yet unknown (1). An attempt.was made therefore to isolate the prosthetic group of sul...

L-chicoric acid is a dominant phenolic compound in lettuce (Lactuca sativa L.) and has been shown to accumulate in response to many abiotic stresses and crop management practices. It is a potent inhibitor of human immunodeficiency virus (HIV-1) integrase needed for the replication of this virus and for the productive infection of the host cell. L-chicoric acid has been found to act synergistica...

This study was performed to investigate the effects of antibiotic, organic acid, probiotic and prebiotic supplementation on performance, egg shell quality, pH value of gastrointestinal (GI) tract and small intestinal morphology of laying hens. The experiment was a completely randomized design with 160 laying hens strain (W-36) from 32 to 42 weeks of age, with five treatments, four replicates an...

Humic substances (HS) reportedly enhance moisture retention of soil. However, no information is available as to the effects of HS on sand-based golf course putting greens. HS have acidic functional groups (COOH) that are reaction sites on the molecule. An greenhouse experiment was conducted to evaluate the effect that the acidic functional groups in humic acid, tannic acid and citric acid have ...
