(Elsevier, 2011)The role of lipopolysaccharide (LPS) in entry of Salmonella Typhimurium into epithelial cells remains unclear. In this study, we tested the ability of a series of mutants with deletions in genes for the synthesis and ...
-
(Frontiers Media, 2016)Listeria monocytogenes has become one of the principal foodborne pathogens worldwide. The capacity of this bacterium to grow at low temperatures has opened an interesting field of study in terms of the identification and ...
-
(MDPI, 2021)Coastal landscapes of the Pacific coast of South America are regarded as bountiful biomes, as they are zones on the fringes of Eastern Boundary Upwelling Ecosystems. Cumulative research shows an almost uninterrupted ...

(Academic Press Inc Elsevier Science, 2015)We study differentiability properties in a particular case of the Palmer's linearization theorem, which states the existence of a homeomorpbism H between the solutions of a linear ODE system having exponential dichotomy ...
-
(OXFORD UNIV PRESS, 2006-02)The yield of 24 commercial varieties and accessions of common bean (Phaseolus vulgaris) has been determined at different sites in Chile and Bolivia. Statistical analysis was performed in order to characterize whether a ...
-
(OXFORD UNIV PRESS, 2006-02)The photosynthetic characteristics of two contrasting varieties of common bean (Phaseolus vulgaris) have been determined. These varieties, Arroz and Orfeo, differ in their productivity under stress conditions, resistance ...

Differential adaptations in nursery seedlings from diverse Chilean provenances of Peumus boldus Mol (SISEF-SOC Italiana Selvicolture Ecol Forestale, 2016)Seed germination, seedling growth and biomass allocation of the endemic species Peumus boldus Mol. (Boldo) were studied in four provenances (two northern and two southern provenances) from central Chile. Seeds collected ...
-
(Taylor & Francis, 2020)We present a type of arithmetic called Proportional Arithmetic. The main properties and objects that emerge with this way of operating quantities are exposed. Finally, the antiderivative and the indefinite integral are ...
-
(Frontiers Media SA, 2017)Melanin is a pigment found in all biological kingdoms, and plays a key role in protection against ultraviolet radiation, oxidizing agents, and ionizing radiation damage. Melanin exerts an antimicrobial activity against ...
-
(Frontiers Media, 2016)Carotenoids and chlorophylls are photosynthetic pigments synthesized in plastids from metabolic precursors provided by the methylerythritol 4-phosphate (MEP) pathway. The first two steps in the MEP pathway are catalyzed ...
-
(2009)Aim: Capsular polysaccharides play an important role in the virulence of Grampositive and Gram-negative bacteria. In Porphyromonas gingivalis, six serotypes have been described based on capsular antigenicity and its ...
-
(2009)PCR and Southern blot hybridization were used to determine the distribution of Trypanosoma cruzi clones in 37 chronic chagasic cardiopathic and non-cardiopathic patients. Parasite DNA amplified from peripheral blood or ...
-
(2003)Introduction. Depression and impulsivity has been associated to a dysfunction of serotonergic system and are treated with serotonin reuptake inhibitors (SSRI). In this work we study differential effects of fluoxetine on ...
-
(1978)The influence of pentazocine on primary cortical evoked potentials was studied in guinea pig under pentobarbital anesthesia. Pentazocine (10 mg/kg, i.v.) increased the latency time of evoked responses to posterior limb ...
-
(Birkhäuser-Verlag, 1986)We have observed a differential effect of silybin dihemisuccinate on rat liver microsonal oxygen consumption and on lipid peroxidation induced by NADPH-Fe2+-ADP and t-butyl hydroperoxide. These results are ascribed to the ...
-
(ROCKEFELLER UNIV PRESS, 2005-04)High conductance, calcium- and voltage-activated potassium (BK) channels are widely expressed in mammals. In some tissues, the biophysical properties of BK channels are highly affected by coexpression of regulatory (beta) ...
-
(Frontiers Media, 2021)Fatty acid overload, either of the saturated palmitic acid (PA) or the unsaturated oleic acid (OA), causes triglyceride accumulation into specialized organelles termed lipid droplets (LD). However, only PA overload leads ...
