(Wiley, 2019)The global increase in the proportion of land cultivated with pollinator-dependent crops implies increased reliance on pollination services. Yet agricultural practices themselves can profoundly affect pollinator supply and ...
-
(2000)The relative gas-phase acidity of halosubstituted acetic acids CH2XCO2H, CHX2CO2H and CX3CO2H (X = F, CI, and Br) is analyzed in terms of global and local descriptors of reactivity. The model is based on the analysis of ...
-
(2003)A detailed analysis of the global and local reactivity patterns of neutral and charged peroxides, including hydrogen peroxide (HOOH), peroxynitric acid (HOONO2), the peroxymonocarbonic ion (HOOCO2-), and the peroxymonosulfate ...
-
(2000)We study the attractivity properties of equilibrium points of the scalar delay difference equation xn+1-xn= -δxn+pf(xn-k) which arises in many contexts in the ecology. New sufficient conditions for the global stability of ...
-
(Elsevier, 2019)Inorganic polyphosphates (polyP) are present in all living cells and several important functions have been de-scribed for them. They are involved in the response to stress conditions, such as nutrient depletion, oxidativestress ...
-
(1994)Based on integral inequalities and on a compactness argument, we will prove global existence results and we will study the asymptotic behavior of solutions of general nonlinear differential systems. © 1994 Academic Press, Inc.
-
(Nature, 2020)The matrilineal long-finned pilot whale presents an antitropical distribution and is divided into two subspecies, one in the temperate seas of the Southern Hemisphere and the other restricted to the North Atlantic and ...
-
(MDPI, 2020)Piscirickettsiasalmonis is an intracellular bacterial fish pathogen that causes piscirickettsiosis, a disease with numerous negative impacts in the Chilean salmon farming industry. Although transcriptomic studies of P. ...
-
(2016)Acidithio bacillus ferrooxidans is used in industrial bioleaching of minerals to extract valuable metals. A. ferrooxidans strain ATCC 53993 is much more resistant to copper than other strains of this microorganism and it ...
-
(Elsevier, 2012)We propose a model of competition of n species in a chemostat, with constant input of some species. We mainly emphasize the case that can lead to coexistence in the chemostat in a non-trivial way, i.e., where the n−1 ...
-
(Elsevier Masson SAS, 2014)© 2014 Institut Pasteur. Tellurite (TeO32-) is harmful for most microorganisms, especially Gram-negative bacteria. Even though tellurite toxicity involves a number of individual aspects, including oxidative stress, ...
-
(SHARED SCIENCE PUBLISHERS, 2016)The universal tRNA modification t(6)A is found at position 37 of nearly all tRNAs decoding ANN codons. The absence of t(6)A(37) leads to severe growth defects in baker's yeast, phenotypes similar to those caused by defects ...
-
(2011)Background: The yeast Xanthophyllomyces dendrorhous is one of the most promising and economically attractive natural sources of astaxanthin. The biosynthesis of this valuable carotenoid is a complex process for which the ...
-
(BMC, 2022)Background Alzheimer's disease is the most prevalent cause of dementia in the elderly. Neuronal death and synaptic dysfunctions are considered the main hallmarks of this disease. The latter could be directly associated to ...
-
(1993)We present a comparative study of Escherichia coli with normal and increased amounts of fructose-1,6-bisphosphate aldolase. Most experiments employed a resting cell system involving a high cell density (so as to obtain the ...
-
(Springer, 2012)The heterologous secretion of xylanase B from Penicillium purpurogenum using glucose as inducer was performed in Aspergillus nidulans. For this purpose, plasmid pEVXB, containing the xylanase B cDNA (including its own ...
-
(BioMed Central Ltd., 2013-02-05)Background: FtsZ is an essential cell division protein, which localizes at the middle of the bacterial cell to mediate cytokinesis. In vitro, FtsZ polymerizes and induces GTPase activity through longitudinal interactions ...
-
(Frontiers Media, 2022)Disruption of the inhibitory control provided by the glycinergic system is one of the major mechanisms underlying chronic pain. In line with this concept, recent studies have provided robust proof that pharmacological ...
-
(Pergamon-Elsevier, 1987)Water deficit increased susceptibility of barley to the aphid Schizaphis graminum. Proline and glycine-betaine accumulated in the stressed plants. These compounds were incorporated into artificial diets to test their effects ...
