(Academic Press Inc., 1995)Eggs of the leech Theromyzon rude were studied under dissecting, fluorescence, light, and electron microscopes. The sperm-derived centrosome divides and separates at early first interphase. The female pronucleus forms ...
-
(1995)The reptilian brain is characterized by a structure that bulges into the lateral ventricle, cabled dorsal ventricular ridge (DVR). The DVR was originally considered to be a part of the basal ganglia, although more recent ...
-
(1995)1. 1. Streptozotocin-induced diabetes produced significant changes on the drug metabolizing enzyme machinery of rat kidney microsomes. 2. 2. It reduced the cytochrome P-450 content by 30%, this effect being reversed by ...
-
(1995)A procedure for recovery and separation of molybdenum (VI) and copper (II) from acid leaching residual solution of Chilean molybdenite concentrate by solvent extraction is studied. The process for the recovery of metals ...
-
(1995)Plant defense against pathogens involves mechanisms that include the expression of several genes, which could be located in any of the three compartments that contain genomes in plant cells: nuclei, mitochondria and ...
-
(TAYLOR & FRANCIS LTD LONDON, 1995-02)The behaviour of a large number of paramagnetic metallo-mesogenic molecules with Cu and VO in different mesophases in a magnetic field was investigated by EPR techniques and magnetic susceptibility measurements. The ...
-
(ELSEVIER SCIENCE BV, 1995-03-01)D-Fructose and 1,10-phenanthroline form complexes with Co(III). Configurations about Co(III) are assigned from the CD and ORD spectra of the separated Lambda and Delta diastereomers, and Lambda strongly predominates in the ...
-
(PORTLAND PRESS, 1995-06)Laccase is one of the ligninolytic enzymes found in liquid cultures of the fungus Ceriporiopsis subvermispora in defined medium. As an approach to a clarification of the role of laccases during the attack on lignin by the ...

-
(PERGAMON-ELSEVIER SCIENCE LTD, 1995-07)This is a first-approach study tending to correlate solar radiation and temperature with total particulate matter in Santiago, Chile, a city heavily polluted by this contaminant. Experimental data for monthly average total ...
-
(ELSEVIER SCIENCE BV, 1995-07-15)The fungus Penicillium purpurogenum produces several extracellular xylanases. The two major forms (xylanases A and B) have been purified and characterized. After ammonium sulfate precipitation and chromatography in Bio-Gel ...
-
(Dustri-Verlag Dr Karl Feistle, 1995-11)Dibekacin pharmcokinetics was studied in 3 healthy volunteers, 5 patients with renal failure presenting Cl-cr, between 4.0 and 67 ml min (-1) per 1.73 m(2) of body surface and 5 anephric patients given as a 30 minute ...
-
(ELSEVIER SCIENCE BV, 1995-12-20)L-Sorbose and two molecules of 1,10-phenanthroline form a complex with Co(III) which has the Lambda configuration about Co(III), based on CD and ORD spectra, The H-1 NMR signals of alpha-L-sorbopyranose and its mixed ...
-
(INIA. Estación Experimental Carillanca, 1996)Se formularon y optimizaron galletas mangueadas con un alto contenido de fibra para suplir parte de los requerimientos nutricionales de los adultos mayores. Se usó fibra de lupino dulce (Vitafiber), y polidextrosa y ...
-
(Instituto Antártico Chileno, 1996)Si bien la Antártica se considera clásicamente como el lugar mas limpio del planeta, el aumento de la actividad humana en ella ha ido modificando lentamente esta apreciación. En este trabajo se estudió la calidad de las ...
-
(CLATCAMA, 1996)The squeezing flow of frankfurte material was studied, using lubrication, at constant compression rate (lmm/s) and area, on three formulation variants containing, respectively, high, medium and low protein contents,(relatively). ...
-
(Sociedad Chilena de Química, 1996)El azometin-ilido de la 2-p-metoxifenil-4-fenil-2-oxazolin-5-ona reacciona por ciclo adición 1,3-dipolar con ambos tautómeros del 1-nitroso-2-naftol. La reacción forma dos naftoxazoles: 2-fenilnafto[1,2-d]oxazol,2-p-met ...
