-
(1988)The enthalpies of the reaction between glutathione and amoxycillin have been measured directly using a flow microcalorimeter. Comparative results are obtained by using an ac polarographic method previously developed in our ...
-
(2008)Properties of inclusion complexes between morin (M) and β-cyclodextrin (βCD), 2-hydroxypropyl-β-cyclodextrin (HPβCD) and Heptakis (2,6-O-di methyl) β-cyclodextrin (DMβCD) such as aqueous solubility and the association ...
-
(2004)To evaluate the potential use of mesquite (Prosopis chilensis (Mol) Stuntz) seed gum, the behaviour of the gum was studied using two extraction methods (alkaline and acid), different pH values, two concentrations (0.2 and ...
-
(1992)Two forms of ATP-diphosphohydrolase were identified in Solanum tuberosum tuber var. Ultimus. Their hydrolytic activity ratios (ATPase/ADPase) were over 10 for form A and 1 for form B. In the potato tuber homogenate the ...
-
(1993)Four sodium polysoaps from poly[malcic anbydride-co-styrene] were synthesized and the surface properties of their aqueous solutions at the air-water interface were determined. The surface tension lowering was directly ...
-
(2004)The oxidation of D-galacturonic acid by Cr-VI yields the aldaric acid and Cr-III as final products when a 30-times or higher excess of the uronic acid over Cr-VI is used. The redox reaction involves the formation of ...
-
(2004)Gelation of fresh (unfrozen) raw surimi-type paste (RS paste) from horse mackerel (T. murphyi) was studied in the presence of κ-carrageenan (0.5, 1, 2% Cκ) and KCl (0.5-2%) as a substitute for NaCl. Gelation was traced by ...
-
(2006)HTLV-1-associated myelopathy/tropical spastic paraparesis (TSP/HAM) is a chronic CNS disease characterized by axomyelinic degeneration of the long axons of corticospinal tracts. Levels of NGF, NT-3, NT-4/5, BDNF, GDNF, ...
-
(2008)A series of five compounds containing the bicyclo-[3.3.0]octa-2,6-diene skeleton are described, namely tetra-methyl cis,cis-3,7-dihydroxy-bicyclo-[3.3. 0]octa-2,6-diene-2,4-exo,6,8-exo-tetracarboxyl-ate, C16H18O10, (I), ...
-
(2002)We discuss a nonhomogeneous population of pulsatil integrate-and-fire neural oscillators, coupled through purely inhibitory synapses. For instantaneous communication, we provide a strategy to generate synaptic couplings ...
-
(Instituto de la Grasa, 2007)The announcement made by Swedish researches in April 2002 concerning the detection of acrylamide in many different foods, has generated a great deal of scientific publications coming from different parts of the world. The ...
-
(2008)Despite many advances achieved to date, heart failure (HF) remains a leading cause of morbidity and mortality. There is a widely-accepted consensus that HF and diabetes are strongly linked by at least 3 mechanisms: associated ...
-
(2004)Biomineralization leads to the formation of inorganic crystals with unique, ordered, refined shapes that are regulated by specific macromolecules. This process has been a source of inspiration for exploring novel approaches ...
-
(2007)The oxydiacetate-bridged copper(II) complex [Cu(oda)(1,10-phen)] · 3H2O (oda = oxydiacetate dianion, 1,10-phen = 1,10-phenanthroline) has been characterized. The complex is dinuclear and centrosymmetric with each copper ...
-
(2004)The synthesis and phase characterization of three homologous series of liquid crystalline acrylic and methacrylic monomers, consisting of 21 new compounds are presented. They are based on ω-hexyloxy- and ω-undecyloxysali ...
-
(2007)The methoxycarbonylation of alkenes catalyzed by palladium(ii) complexes with P,N-donor ligands, 2-(diphenylphosphinoamino)pyridine (Ph 2PNHpy), 2-[(diphenylphosphino)methyl]pyridine (Ph 2PCH2py), and 2-(diphenylphosphin ...
-
(2007)Three new dinuclear Zn(II) complexes [Zn(L)(μ1,1-N3)Zn(L)(N3)] · 1.5H2O (1), [Zn(L)(μ1,1-NCO)Zn(L)(NCO)] · 1.5H2O (2) and [Zn(L)(μ1,1-NCS)Zn(L)(NCS)(OH2)] (3) have been synthesized from a potentially tetradentate N2O2-donor ...
-
(1980)We describe a procedure for the preparation of various metal thiourea complexes of the type [M(CO)5L] in which M Cr or W and L TU (thiourea), TMTU (tetramethylthiourea), DptTU (NN′-di-p-totyl thiourea); DtBTU = (NN′-di-t-butyl ...
-
(2007)Hepcidin (Hepc) is considered a key mediator in iron trafficking. Although the mechanism of Hepc action in macrophages is fairly well established, much less is known about its action in intestinal cells, one of the main ...
-
(Society of Biology of Chile, 2007)The antioxidant effect of 5-Aminosalicylic acid (5-ASA) on copper-mediated LDL oxidation was followed either by the emitted chemiluminiscence (CL) or by UV-vis spectroscopy. 5-ASA addition extends the lag phase in a ...
