(Entomological Society of America, 1997)Aphid genotype has been shown to be a source of variability in the induction of phytochemical responses in wheat after aphid infestation as well as in their performance on wheat lines. Two clones of the aphid Sitobion ...
-
(ELSEVIER SCIENCE INC, 2008-05)Because immune function competes for the resources that can be allocated to other activities, studies of immunological ecology may offer a powerful tool for explaining how reproductive effort links to reproductive costs ...
-
(2012)Phylogenetic diversity (PD) is commonly calculated by adding together the branch lengths or ages of a subset of taxa present in an area, using a single phylogeny as a backbone. However, a phylogenetic hypothesis is the ...
-
(Springer, 2017-05-09)Background: Patterns of seed germination and subsequent seedling growth of the endemic species Nothofagus glauca (Phil.) Krasser (Lophozonia glauca) (Hualo) were studied in two provenances from Mediterranean Central Chile ...
-
(BLACKWELL VERLAG GMBH, 2004-08)The ability to assess and respond to predation risk is a strong selective force. Detection of predators is carried out by one or more sensory modalities, but the use of chemoreception has significant advantages. This study ...
-
(Oxford Univ Press, 2016)We present for the first time a direct comparison of multi-epoch (2001-2002 and 2012) CO ro-vibrational emission lines from HD 163296. We find that both the line shapes and the FWHM (full width at half-maximum) differ ...
-
(Biomed Central Ltd., 2017)Brucella canis is a small intracellular Gram-negative bacterium whose primary host is the dog, but it also can cause mild human brucellosis. One of the main causes of an inefficient immune response against other species ...
-
(2008)Background and Objective: Dendritic cells are able to prime and polarize naïve T cells towards either a T helper 1 or a T helper 2 response, depending on the antigen type and concentration, the costimulatory signals and ...
-
(Lippincott Williams and Wilkins, 2015)© 2015, Otology & Neurotology, Inc. Hypothesis: Based on a three-dimensional analysis, the orientation of the basal turn of the cochlea, the disposition of the basilar membrane, and the characteristics of the hook region ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2011-03)The use of Synthetic Aperture Radar interferometry (InSAR) in northern Chile, one of the most seismically active regions in the world, is of great importance. InSAR enables geodesists not only to accurately measure Earth's ...
-
(Elsevier, 2016)The variability of radiocarbon marine reservoir age through time and space limits the accuracy of chronologies in marine paleo-environmental archives. We report here new radiocarbon reservoir ages (Delta R) from the central ...
-
(Universidad de Valparaíso, 2015)The chain of islands including Desertores, Apiao and Quemchi located in the Inner Sea of Chiloé, in northern Chilean Patagonia (41°- 44°S), acts as a natural barrier for the flux of water in the north-south direction, ...

Variability of formulas to assess insulin sensitivity and their association with the Matsuda index (2013)Objetivo: Evaluar la variabilidad individual de los índices HOMA y QUICKI para resistencia a insulina, utilizando tres muestras de sangre en ayunas obtenidas en un período de 30 minutos. Material y métodos: Se utilizaron ...
-
Variability of glycemic and insulin response to a standard meal, within and between healthy subjects (Universidad de Chile, 2013)Objetivo: Evaluar la variabilidad inter e intra individual de la respuesta glicémica frente a la ingestión de un alimento estándar en sujetos sanos. Material y métodos: Se midió en 6 oportunidades la respuesta glicémica ...
-
(2013)Aim: To test the variability within and between subject of glycemic response test following the ingestion of a standard food. Material and methods: Glucose and insulin response of a standard meal (white bread) was performed ...
-
(American Academy of Periodontology, 2015)Background: Different serotypes of Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis have been shown to induce differential dendritic cell (DC) responses. This study investigates whether cytokine and ...
-
(1995)The analysis of heart rate variability studies the normal oscillatory changes of the cardiac cycle. These changes are periodical or incidental and are controlled by humoral, sympathetic and parasympathetic stimuli. Frequency ...
-
(2012)Lidar instruments have proven useful for characterizing the structure and dynamics of aerosol layers. We compare here the diurnal, seasonal and vertical variability of urban aerosols as described by a lidar ceilometer and ...
-
(2010-04-06)The aim of this study was to investigate, during the summer of the year 2008, the variation in leaf water and photosynthetic characteristics of Eucryphia cordifolia Cav. (Cunoniaceae) along its broad latitudinal ...
