(ELSEVIER, 2011-03-15)This paper deals with two varieties of commutative non-associative algebras. One variety satisfies L(x)(3) + L(x)(3) = 0. The other variety satisfies L(x)(3) = 0. We prove that in either variety, any finitely generated ...

(AMER SOC BIOCHEMISTRY MOLECULAR BIOLOGY INC, 2011-02-18)Substrate inhibition by ATP is a regulatory feature of the phosphofructokinases isoenzymes from Escherichia coli (Pfk-1 and Pfk-2). Under gluconeogenic conditions, the loss of this regulation in Pfk-2 causes substrate ...
-
(SOC BIOLGIA CHILE, 2011)Epithelial and neuronal cells are highly asymmetric, with discrete regions responsible for different roles that underlie the generation of specific compartments within cells that are distinct in biochemical composition, ...
-
(AMER INST PHYSICS, 2011-01)Based on the one-body particle-antiparticle Dirac theory of electrons, a set of relativistic quantum fluid equations for a spin half plasma is derived. The particle-antiparticle nature of the relativistic particles is ...

-
(Human Sciences Press, 1989)The authors present a neurobiological model for near-death experiences (NDEs) in an attempt to correlate the biological and psychological domains. This model is based on temporal lobe dysfunction, hypoxia/ischemia, stress, ...
-
(Kluwer Academic Publishers, 1995-01-10)A non-empirical Quantitative Structure-Activity Relationship (QSAR) method is employed to analyze the reversible complex formation during the reaction of phenyl-N-methylcarbamates with the enzyme acetylcholinesterase. ...
-
(American Chemical Society, 1991-01-02)New developments in the continuum representation of solvent effects are presented. General expressions for the Helmholtz free energy of an arbitrary discrete charge distribution placed in spherical and spheroidal (oblate ...
-
(University of Tehran., 2003-09-06)We present here the results of a formal structure-property relationship study carried out for 1 CB - and 2 CB -mediated inhibition of adenylyl cyclase (ADC) by a group of classical cannabinoid derivatives. The wave ...
-
(John Wiley & Sons, Inc., 1998-09-28)A quantum-chemical structure]affinity relationship for kynurenic acid derivatives KA. acting at the GlyrNMDA site is presented. The results of this study strongly suggest that these molecules bind to this site through ...
-
(American Chemical Society, 1984)SCF-CNDO/2 calculations, including the continuum solvent effects via an extended version of the generalized Born formula, have been performed for H30+.-.(H20),..a-ndO H(-H 20),..-H.3O0Ht--s p.ec ies (n = 0, 1,2). The ...
-
(SOC CHILENA QUIMICA, 2009-12)The problem of negative electronic populations and of occupation numbers greater than 2 has plagued Mulliken Population Analysis since the very beginning. Through the analysis of three model molecular systems, several basis ...
-
(AMER SCIENTIFIC PUBLISHERS, 2009-06)The existence of a minimal molecular model to represent some electronic properties of nanostructures is analyzed for several kinds of nanotubes and graphene surfaces by using the Extended Hückel Theory. It is shown that ...
-
(CSIRO PUBLISHING, 2010)Ingestion of parathion produces catastrophic effects on mammals. Transformed into paraoxon, it inhibits acetylcholinesterase, producing acetylcholine accumulation. The distribution, orientation, and dynamics of parathion ...
-
(AMER CHEMICAL SOC, 2011-03-17)The MRKDV peptide, structurally associated 9 with an immunomodulatory protein, was studied using surface 10 enhanced Raman scattering (SERS), molecular dynamics (MD) 11 simulations, and quantum chemical calculations. ...
-
(JOHN WILEY & SONS INC, 2011-09-08)Raman and surface-enhanced Raman scattering (SERS) spectra of the synthetic carboxy terminal peptide of human chorionic gonadatropin b-subunit free of carbohydrate moieties (P37) are reported. The spectral analysis is ...
-
(American Chemical Society, 1989-09-28)We present a theoretical treatment for the Helmholtz free energy of an arbitrary discrete charge distribution in a central prolate or oblate spheroidal cavity surrounded by two and three concentric dielectric continua of ...
-
(John Wiley and Sons, Inc., 1982-11-05)We performed an analysis of the drug-receptor equilibrium constant, Ki = {Q,,,Q;tQ,'} exp (-A&JkT). It is shown that, for a group of nonrotating molecules, we may consider the product of the partition functions as constant ...
-
(ELSEVIER, 2011-04-01)An earthquake network is known to be of the small-world type. The values of the network's characteristics, however, depend not only on the cell size (i.e., the scale of coarse graining needed for constructing the network) ...

(SPRINGER, 2009-10-06)Larval identiWcation represents a powerful tool for detailed studies on recruitment and population dynamics in marine invertebrates. However, intra-speciWc morphological variation can become a serious limitation for ...
