the purification, properties and characterization of three forms of alpha-l-fucosidase from monkey brain.	alpha-l-fucosidase (alpha-l-fucoside fucohydrolase, ec 3.2.1.51) has been purified to apparent homogeneity (about 22 000-fold over the crude homogenate) from monkey brain. values of kinetic constants for the purified enzyme were as follows: ph optimum, 5.0; km, 0.22 mm; v, 913 mumol/mg per h. alpha-l-fucose was a competitive inhibitor (ki, 0.275 mm) of the enzyme. evidence for the involvement of sulphydryl group(s) and carboxyl group containing amino acid(s) in the catalytic process is presented ...	1978	96860
phycobiliprotein synthesis in protoplasts of the unicellular cyanophyte, anacystis nidulans.	stable and metabolically active protoplasts were prepared from the unicellular cyanophyte, anacystis nidulans, by enzymatic digestion of the cell wall with 0.1% lysozyme. the yield of protoplasts from intact algal cells was approx. 50%. incorporation of l-[u-14c]leucine into cold trichloroacetic acid-insoluble material from protoplasts preparations was linear for 1.5 h and continued for an additional 2.5 h. incorporation of radiolabeled leucine into hot trichloroacetic acid-insoluble material fr ...	1978	96857
differential effects of prostaglandin synthetase stimulators on inhibition of cyclooxygenase.	the different effects of prostaglandin synthetase stimulators on inhibition of the cyclooxygenase by structurally distinct classes of nonsteroidal antiinflammatory agents suggest that the enzyme is altered by interaction with these stimulators. reversible stimulation of prostaglandin synthetase activity by phenols and some other compounds and the relative influence of these stimulators on inhibitors of the cyclooxygenase were determined quantitatively. two distinct classes of inhibitors were est ...	1978	96853
behaviour of solute and particle markers in the stomach of sheep given a concentrate diet.	1. fistulated sheep given a concentrate diet were used to study the behaviour of solute ([51cr]edta) and particle ([103ru]phenanthroline) markers in the stomach under conditions of continuous feeding. 2. an injection of a mixed dose of [51cr]edta and [103ru]phenanthroline was given into the rumen and the time course of marker concentrations in the rumen and the abomasum was recorded. the curves were analysed on the assumption that the stomach of the sheep could be represented as two mixing compa ...	1978	96850

phospholipid content and activity of pure uridine diphosphate-glucuronyltransferase from rat liver.	rat liver phospholipids were radioactively labeled in vivo before purification of udp-glucuronyltransferase to homogeneity. the pure enzyme contained very little phospholipid (approx. 0.7 mol of phospholipid/mol of protein). the solubilization detergent lubrol 12a9 appeared to act as a phospholipid substitute, capable of supporting udp-glucuronyltransferase activity. phospholipase c did not inhibit the pure enzyme activity and pure udp-glucuronyltransferase was stimulated by 40--100% by the addi ...	1978	96816

[the myocardiopathies of hereditary neuro-muscular diseases].	this joint work has studied the cardiomyopathies occurring in hereditary neuro-muscular disorders (270 cases). the duchenne type of disorder (74 cases) was responsible for asystole (4 cases), for cardiomegaly, and especially for abnormalities of the ecg (59 cases)--q waves and large r waves in v1 and v6. the cardiomyopathy was of the hypokinetic type, with histological evidence of degeneration of the myocardial fibres. dystrophia myotonica of steinart (23 cases) caused conductive disorders (17 c ...	1999	96758
sodium iron nafeedta as an iron fortification compound in central america. absorption studies.	studies were performed in seven children and 98 adults to compare the proportion of iron absorbed when administered as ferric sulfate (fe2(so4)3), nafeedta, hemoglobin (hb), and ferrous ascorbate. studies in children (mostly iron deficient) showed that when the compounds were given with a milk-rice-sugar formula totalling 5 mg fe, iron from hemoglobin was absorbed best, followed by nafeedta and by fe2(so4)3 (mean percent absorption +/-sd = 34.5 +/- 1.5, 8.6 +/- 1.9 and 3.3 +/- 1.5, respectively) ...	1999	96688
