Characterization and analysis of conserved motifs in a peroxisomal ATP-binding cassette transporter (The American Society forBiochemistry and Molecular Biology, Inc., 1996)The adrenoleukodystrophy protein (ALDP) and the 70-kDa peroxisomal membrane protein are half ATP-binding cassette (ABC) transporters in the human peroxisome membrane. Both are implicated in genetic disorders of peroxisome ...

(NEW YORK ACAD SCIENCES, 1996)The adrenoleukodystrophy protein (ALDP) and the 70-kDa peroxisomal membrane protein (PMP70) are half ATP binding cassette (ABC) transporters in the peroxisome membrane. ALDP is defective in X-linked adrenoleukodystrophy ...
-
(Universidad Nacional del Sur y Consejo de Investigaciones Científicas y Técnicas, 1996)The etherification reaction of mechanic pulp (MP) with dimethylsulphate (DMS) in homogeneous media was studied using a 2 5-1 fractional factional experimental design. In according to this model the quantity of DMS/2 g ...
-
(Asociación Chilena de Microbiología, 1996)Las xilanasas son enzimas, producidas por hongos y bacterias que degradan el xilano de las hemicelulosas vegetales y tienen una importante aplicación en el bioblanqueamiento de la celulosa. A partir de compost, se ...
-
(MARCEL DEKKER INC, 1996)A continuous flow injection reaction-stopped flow detection method using derivative spectrophotometry was developed for the determination of cobalt and iron in mixtures. A conventional two-channel flow injection manifold ...
-
(GORDON BREACH SCI PUBL LTD, 1996)Structural investigations using X-ray diffraction on methacrylate and acrylate based polymers with different side-chain mesogenic units are presented. The measurements were carried out by means of diffractometers with one ...
-
(1996)The antipyretic and antiinflammatory properties of the infusions and methanol extracts of the whole plant of Cuscuta chilensis Ker-Gawl. and of the aerial parts of Cestrum parqui L'Herit. and Psoralea glandulosa L. were ...
-
(Elsevier B.V., 1996)Loratadine, a potent antihistamine drug, is not directly electroreducible at a dropping mercury electrode; however, by means of a nitration procedure it is possible to obtain a nitro-loratadine derivative which has been ...
-
(1996)The preparation of the copper(II) complex formulated as [Cu(DPA)(Ac)2]·2H2O is given (DPA: di(2-pyridyl)amine, Ac: acetate). The structure of this complex was determined by single-crystal X-ray analysis. It crystallizes ...
-
(Elsevier Ireland Ltd, 1996)The reactivity of the electrochemically generated nitro radical anion from nifedipine, a nitro aryl 1,4-dihydropyridine derivative, with relevant endobiotics and thiol-containing xenobiotics, was quantitatively assessed ...
-
(Marcel Dekker Inc.Taylor & Francis, 1996)The EPR spectra of radicals obtained by electrohytical reduction of 2-nitroimidazole and 4-nitroimidazole were measured in mixed solvents. The behavior of the nitrogen coupling constants with the solvent composition is ...
-
Study of a procedure for the obtainment of methylcellulose from mechanic pulp in homogeneous media (1996)The etherification reaction of mechanic pulp (MP) with dimethylsulphate (DMS) in homogeneous media was studied using a 25-1 fractional factorial experimental design. In according to this model the quantity of DMS/2 g of ...
-
(Swets en Zeitlinger B.V., 1996)The antipyretic and antiinflammatory properties of a new sesquiterpene, spartidienedione, isolated from Psila spartioides (Asteraceae) were evaluated in rabbits and guinea pigs. At the dose of 25 mg/kg, this substance ...
