(1996)Wheats and triticales resistant to Russian wheat aphid (RWA). Diuraphis noxia, contained medium to very high concentrations of hydroxamic acids. Feeding behaviour and performance of RWA in wheat seedlings differing in ...
-
(ELSEVIER SCIENCE BV, 2008-06)Inducible defenses are a form of phenotypic plasticity that potentially modify direct interactions between various members of an ecological community, generating traitmediated indirect effects. In this work, the hypothesis ...

(1986)Enzyme preparations with variable phospholipid contents were obtained by removing lipids from sarcoplasmic reticulum with deoxycholate. Preparations containing from 90 to 37 phospholipids per enzyme showed normal values ...
-
(Springer, 2015)Human ribokinase (RK) is a member of the ribokinase family, and is the first enzyme responsible for D-ribose metabolism, since D-ribose must first be converted into D-ribose-5-phosphate to be further metabolized and ...
-
(BLACKWELL, 2009)The idea that alterations in the brain immunomodulation are critical for Alzheimer’s disease (AD) pathogenesis provides the most integrative view on this cognitive disorder, considering that converging research lines ...
-
(SOC BIOLGIA CHILE, 2006)In mammals, neurogenesis continues during adulthood in restricted places of the nervous system, namely the subventricular zone, the dentate gyrus and the olfactory epithelium. A dual role of the second messenger nitric ...
-
(Hindawi Publishing Corporation, 2014)© 2014 Rodrigo A. Quintanilla et al.Neuronal processes (neurites and axons) have an important role in brain cells communication and, generally, they are damaged in neurodegenerative diseases. Recent evidence has showed ...

(Frontiers Media S.A., 2017)© 2017 Torrent, Gil-Durán, Rojas-Aedo, Medina, Vaca, Castro, García-Rico, Cotoras, Mendoza, Levicán and Chávez. The sfk1 (suppressor of four kinase) gene has been mainly studied in Saccharomyces cerevisiae, where it was ...
-
(2010)X-ray diffraction data on a few retroviral integrases show a flexible loop near the active site. By sequence alignment, the peptide region 207-218 of Mo-MLV IN appears to correspond to this flexible loop. In this study, ...
-
(2002)Protein kinase CK2 (also known as casein kinase 2) has catalytic (α, α′) and regulatory (β) subunits. The role of carboxyl amino acids in positions from 324 to 328 was studied for Xenopus laevis CK2α. Deletions and mutations ...

(AMER SOC BIOCHEMISTRY MOLECULAR BIOLOGY INC, 1998-12-04)We investigated the role of individual charged residues of the S4 region of a MaxiK channel (hSlo) in channel gating, We measured macroscopic currents induced by wild type (WT) and point mutants of hSlo in inside-out ...
-
(ELSEVIER, 2008)Phytomonitoring techniques for irrigation of avocado orchards indicate that plants respond very rapidly to fluctuations in soil water content. Root to leaf abscicic acid transport cannot fully explain the almost immediate ...
-
(Polish Acad. Sciences Inst. Mathematics-Impan, 2015)A commutative order in a quaternion algebra is called selective if it is embeds into some, but not all, the maximal orders in the algebra. It is known that a given quadratic order over a number field can be selective ...
-
(Taylor & Francis, 2017)Alzheimer’s disease is a common tauopathy where fibril formation and aggregates are the hallmark of the disease. Efforts targeting amyloid-b plaques have succeeded to remove plaques but failed in clinical trials to improve ...
-
(Japan Society for Analytical Chemistry, 2014)This study demonstrates the first use of polydimethylsiloxane (PDMS) immobilized on a rotating disk for the extraction of copper from aqueous matrices and its subsequent direct determination by solid phase UV-Visible ...
-
Ruthenium carbonyl complexes in catalytic epoxidation of olefins co-catalyzed by isobutyl-aldehyde (JOHN WILEY & SONS LTD, 2006-04)The present work shows the catalytic activity of a series of carbonyl ruthenium complexes in the epoxidation of olefins co-catalyzed by isobutyl-aldehyde. The complexes display catalytic activity in the epoxidation of the ...
