(NATL ACAD SCIENCES, 2000-11-21)The voltage- and Ca2+-acttiated K+ (K-V,K-Ca) channel is expressed in a variety of polarized epithelial cells seemingly displaying a tissue-dependent apical-to-basolateral regionalization, as revealed by electrophysiology. ...
-
(BIOPHYSICAL SOCIETY, 2001-05)The mechanism by which the cytoskeletal protein actin affects the conductance of amiloride-sensitive epithelial sodium channels (ENaC) was studied in planar lipid bilayers. In the presence of monomeric actin, we found a ...
-
(ELSEVIER, 2006-10-01)Magnetic properties of sulfide spinels derived from the lutetium manganese thiospinel MnLu2S4 are reported. In this first approach, we have partially substituted lutetium by other lanthanides or by some transition metal ...
-
(MARCEL DEKKER INC, 2001-01-12)Salicylideneaniline presents an electronic absorption band spectrum of complex patterns between 200 and 450 nm. However, we have successfully developed the electronic transition assignments of this molecular compound and ...
-
(ELSEVIER SCIENCE BV, 2006-01-25)Indoline-2-thione (BC) and benzimidazole-2-thione (BN) are two aromatic compounds containing a NCS synthonic unit in a heterocyclic ring of five centres, where the main electronic absorption bands are localized in the ...
-
(URBAN & FISCHER VERLAG, BRANCH OFFICE JENA, 2005-03)Changes in the activity of catalase (Cat) and in the levels of H2O2 were followed throughout dormancy in buds of grapevines (Vitis vinifera L.). In grapevines grown in the Elqui valley in Chile, a region with warm-winters, ...
-
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2003-11)We report multiproxy analyses of a sediment core obtained from Laguna Aculeo that spans the past 7500 years. Laguna Aculeo (33degrees50'S, 70degrees55'W) is one of the few natural inland lakes located in the Mediterranean ...
-
(ELSEVIER, 2003-10)The recent availability of an incomplete genomic sequence from Acidithiobacillus ferrooxidans allowed us to continue and strengthen the demanding task of investigating the proteome and its functional implications in this ...
-
(ELSEVIER, 2003-11)The mode of action of cyclosporine (CsA) has been ascribed to its capacity to inhibit IL-2 and IFNgamma production by T cells, two cytokines implicated in allograft rejection. Recently, it has been reported that upon ...
-
(NATL ACAD SCIENCES, 2003-11-25)GFP-promoter experiments have previously shown that at least nine genes encoding potassium channel subunits are expressed in Caenorhabditis elegans muscle. By using genetic, RNA interference, and physiological techniques ...
-
(ELSEVIER SCI LTD, 2005-07)Some selected issues regarding integrated pest management (IPM) development and adoption in Latin America are explored in relation to the characteristics of Latin American farmers, and the strategies of donors and practitioners ...
-
(ELSEVIER, 2003-11-28)We have carried out an ab initio study designed to shed some light on the aurophilic attractions between Au(I) and Au(III) in the [PH3Au(I)C(L)=C(L)Au(III)(R)(2)PH3] (where R = -H, -CH3; L = -H, -CH3) model. Calculations ...
-
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2003-12-01)The properties of the microheterogeneous systems formed by mixtures of cetyltrimethylammonium bromide (CTAB) and an alternating copolymer of maleic acid and styrene, MAS, and their anionic monoesters, MAS-n with n = 2, 4, ...
-
(ELSEVIER SCIENCE, 2003-10-15)We demonstrate how to improve the switching power and performance of all-optical nonlinear couplers by introducing linear control waveguides. In particular, we demonstrate this idea for a three-core coupler consisting of ...
-
(ELSEVIER SCIENCE, 2003-10)Candidate genes have been identified in the almost complete genome sequence of Acidithiobacillus ferrooxidans that are potentially involved in several physiological processes of relevance to the application of this ...
-
Binding of microtubule-associated protein 1B to LIS1 affects the interaction between dynein and LIS1 (PORTLAND PRESS LTD, 2005-07-15)For neuronal migration to occur, the cell must undergo morphological changes that require modifications of the cytoskeleton. Several different MAPs (microtubule-associated proteins) or actin-binding proteins are proposed ...
-
(ELSEVIER SCIENCE, 2005-07)It has been suggested that complementary proteins are involved in autoimmunity through a network involving idiotype-anti-idiotype reactions termed 'autoantigen complementarity'. We propose that complementary proteins, which ...
-
(PERGAMON-ELSEVIER SCIENCE, 2005-01-24)The global electrophilicity index evaluated at the ground state of benzylating and acylating agents shows a quantitative linear relationship with the experimental substrate selectivity index evaluated for a series of ...
-
(Elsevier, 2005)We studied the attraction between [Pt(PH3)(3)] and Tl(I) in the [Pt(PH3)(3)]-Tl+ complex using ab initio methodology. We found that the changes around the equilibrium distance Pt-Tl and in the interaction energies are ...
-
(ELSEVIER SCIENCE BV, 2005-03-29)The electrochemical reduction of carbon dioxide was studied on a glassy carbon electrode modified with either polymeric M-tetrakis aminophthalocyanines (M = Co, Ni, Fe) or with the polymeric free ligand, in aqueous ...
