Subcellular remodeling of the T-tubule membrane system: The limits of myocardial recovery revealed? (Lippincott Williams and Wilkins, 2017)
-
(SOC MEDICA SANTIAGO, 2008-09)Background: Type I familial hyperaldosteronism is caused by the presence of a chimaeric gene CYP11B1/CYP11B2 which encodes an enzyme with aldosterone synthetase activity regulated by adernocorticotrophic hormone (ACTH). ...
-
(AOAC INTERNATIONAL, 2006-04)A rapid and simple continuous method for the extraction of nifedipine from tablets was developed by using pressurized hot water at 150 degrees C. This is the first time that subcritical water was applied to the extraction ...
-
(2006)Copper-embedded low-density polyethylene (LDPE) composites were fabricated using different copper concentrations in the polymer matrix. The copper particles were spherical with a mean particle size between 200 and 300 nm. ...
-
(Elsevier B.V., 2017)Tetra-tert-butyl-cis,cis-3,7-dihydroxybicyclo[3.3.0]octa-2,6-diene-2,4-exo-6,8-exo-tetracarboxylate (I) and tetra-tert-butyl-cis,cis-3,7-dimethoxybicyclo[3.3.0]octa-2,6-diene-2,4-exo-6,8-exo-tetracarboxylate (II) were ...
-
(ELECTROCHEMICAL SOC INC, 2009)The electrochemical reduction of 1-methyl-4-nitro-2-carboxyimidazole (RNO2COOH) in a nonaqueous medium produced two reduction signals, which were influenced by the dissociation of the compound. The first reduction signal ...
-
(Elsevier Science SA, 2018)Lercanidipine (LERCA) is a third generation antihypertensive drug belonging to the 1,4-dihydropyridine's family, which has been reported to induce photoallergic and/or phototoxic effects in patients with long term treatment. ...
-
(The American Society of Photobiology, 2014)The electronic nature of substituents attached to the 4-aryl moiety of 1,4-dihydropyridines strongly affects the photophysical and photochemical behavior of these family of compounds. The presence of an electron donor ...
-
(CHEMICAL SOC JAPAN, 2002-09)Hydroxyl and phenyl radical spin trapping rates by alpha-phenyl-N-t-butylnitrone (PBN, N-benzylidene-t-butylamine N-oxide) and its analogs were determined using a competitive trapping method. Hydroxyl radical was generated ...
-
(1994)AM1 full geometry optimization of seven substituted cyclic hydroxamic acids (Hx) was performed. A qualitative correlation between Elumo vs Hammett's σP was observed. The reactivity of these 7-substituted Hx with hard ...
-
(ELECTROCHEMICAL SOC INC, 2001-10)We have synthesized three nitrocompounds in order to mimic the model structure of some relevant drugs such as nifedipine, nitrendipine, nisoldipine, nimodipine, and related ones, in order to investigate the effect of ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2005-06-28)The title compound (sucrose Co(phen)(2)) is a dication with the Delta-configuration at Co(III) and ligation through O-2(g) and OH-1(f). Earlier geometrical optimization with semi-empirical PM3(tm) parameters had fitted ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2002-10-01)The two 1,10-phenanthroline ligands in the mixed Delta-cobalt(III) complex with sucrose are in different environments relative to the sucrose ligand as shown by differences in their H-1 NMR signals and predicted by structural ...
-
(PUBLIC LIBRARY SCIENCE, 2011-12-28)One of the several uses of sucrose detergents, as well as other micelle forming detergents, is the solubilization of different membrane proteins. Accurate knowledge of the micelle properties, including size and shape, are ...
-

-
(MDPI, 2022)Simple Summary Honey is biologically desirable for antioxidant powers and antiradical capacities. However, pesticide use in farming means that any nearby beehives might become contaminated with undesirable and often harmful ...
-
(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 ...
-
(2005)A series of phenethylamine derivatives with various ring substituents and with or without N-methyl and/or C-alpha methyl or ethyl groups was synthesized and assayed for their ability reversibly to inhibit monoamine oxidase ...
-
(2011)The intracellularly-occurring Cu(I)-glutathione complex (Cu(I)-[GSH](2)) has the ability to reduce molecular oxygen into superoxide radicals (O-2(center dot-)). Based on such ability, we addressed the potential of this ...
