(2011)The strict application of IUPAC rules for the numbering of tropane alkaloids is not always applied by authors and there is hence a lot of confusion in the literature. In most cases, the notation of 3, 6/7-disubstituted ...
-
(2011)Triphenylphosphonium ylidic keto diesters with a nonylidic ester group, Ph3PC(CO2CH2CH3)COCO 2CH2CH3, 1, and Ph3PC(CO 2CH2CH3)COCH2CO2CH 2CH3, 2, have the keto group syn and the ylidic ester acyl group anti to phosphorus. ...
-
(2011)Amyloid β-peptide (Aβ) is the main component of the amyloid plaques associated with Alzheimer's disease (AD). In the early steps of the disease soluble Aβ oligomers are produced. According to the current "amyloid hypothesis" ...
-
(2011)Hybrid organic-inorganic semiconductor nanocomposites of layered zinc oxide/carboxylic acids were fabricated. Products are pure phases with structures constituted by double-layer sheets of the inorganic component sandwiched ...
-
(2011)Modulational instability and discrete matter wave solitons in dipolar BECs, loaded into a deep optical lattice, are investigated analytically and numerically. The process of modulational instability of nonlinear plane ...
-
(2011)Negative density-dependent relationships in plant communities are currently claimed as an important mechanism for the maintenance of plant diversity. However, anthropogenic perturbations such as forest fragmentation might ...
-
(2011)We study the scattering of magnetoinductive plane waves by internal (external) capacitive (inductive) defects coupled to a one-dimensional split-ring resonator array. We examine a number of simple defect configurations ...
-
(2011)During the 1H NMR study of the photoreduction of aza-oxoisoaporphines, aza-OIAs, (7H-benzo[e]perimidin-7-ones) by amines we found an unexpected H/D isotopic exchange in the aromatic positions 4 and 6 of these molecules. ...
-
(2011)The nature of life has been a topic of interest from the earliest of times, and efforts to explain it in mechanistic terms date at least from the 18th century. However, the impressive development of molecular biology since ...
-
(2011)Virus infections in grapevine cause important economic losses and affect fruit quality worldwide. Although the phenotypic symptoms associated to viral infections have been described, the molecular plant response triggered ...
-
(2010)The analysis of a 10 000 calendar year (cal. ka) pollen record on the west coast of Tasmania has revealed a suite of changes that can be related to sea level, fire and people. Fire-promoted moorland has occupied the site ...
-
(Pontificia Universidad Catolica de Chile, Facultad de Agronomia e Ingenieria Forestal, 2011)The quality requirements that consumers consider in their decision to purchase fresh fruit have garnered a great deal of attention from the actors in the fresh fruit productivity chain. This study seeks to identify attributes ...

Some Thoughts on A. H. Louie's "More Than Life Itself: A Reflection on Formal Systems and Biology" (2011)We review and discuss A. H. Louie's book "More than Life Itself: A Reflexion on Formal Systems and Biology" from an interdisciplinary viewpoint, involving both biology and mathematics, taking into account new developments ...
-
(2011)Pathological tau protein aggregates can be found in brain of patients with some of the neurodegenerative diseases collectively known as tauopathies, which include Alzheimer's disease (AD). Since tau post-translational ...
-
(2011)We report the photochemical method to synthesize Ga2O 3Dy3Co3 and Ga2O3Dy 3Cr3 thin films. X-ray photoelectron spectroscopy, X-ray diffraction and photoluminescence were used to characterize the products. These analyses ...
-
(2011)A theoretical study of methanol decomposition using a model representing the initial step of the reaction CH 3 OH + CuO → CH 2 O + H 2 O + Cu is presented. Theoretical calculations using B3LYP/6-31 G along with Lanl2DZ ...
-
(2011)The expression of phenotypically plastic traits in prey organisms, triggered by changes in the abundance of their predators, is customarily assumed to involve costs in some fitness components such as fecundity, growth or ...
-
(2011)During tissue morphogenesis and differentiation, cells must self-renew while contemporaneously generating daughters that contribute to the growing tissue. How tissues achieve this precise balance between proliferation and ...
-
(2011)Background: Dendritic cells (DCs) are professional antigen-presenting cells able to induce immunity or tolerance. The interactions of immature DCs with naive T lymphocytes induce peripheral tolerance through mechanisms ...
-
(2010)Herbivory rates are generally thought to be higher in tropical than in temperate forests. Nevertheless, tests of this biogeographic prediction by comparing a single plant species across a tropical-temperate range are scarce. ...
