(ELSEVIER, 2006-01-13)A new mass spectrometry/gas chromatography-mass spectrometry (MS/GC-MS) approach has been developed for the screening and quantitative determination of perchloroethylene (PERC) in workplace and outdoor air samples, which ...
-
(Springer, 2018-08)Jumbo squid is an important marine resource commercialized in Chile as well as American countries such as PerA, Mexico, and USA. In order to find the best conditions for prevention of squid meat degradation, this study ...
-
(OXFORD UNIV PRESS, 2002-10)BACKGROUND: The aim of this study was to evaluate the peripheral serum androgen concentrations in normal and polycystic ovarian syndrome (PCOS) women during pregnancy, in order to establish if PCOS may induce gestational ...
-
(Society for Reproduction and Fertility, 2014)Chronic cold stress applied to adult rats activates ovarian sympathetic innervation and develops polycystic ovary (PCO) phenotype. The PCO syndrome in humans originates during early development and is expressed before or ...
-
(American Physiological Society, 2013)© 2013 The Authors. Fetal brain hypoxic injury remains a concern in high-risk delivery. There is significant clinical interest in agents that may diminish neuronal damage during birth asphyxia, such as in allopurinol, an ...
-
(Wiley, 2014)Drying kinetics of Cape gooseberry was studied and modeled during processing at four temperatures (60, 70, 80 and 90C). Desorption isotherm was obtained at 40C giving a monolayer moisture content of 0.086 g water/g d.m. ...
-
(ACS Publications, 2018-05)A single stress exposure facilitates memory formation through neuroplastic processes that reshape excitatory synapses in the hippocampus, probably requiring changes in extracellular matrix components. We tested the hypothesis ...
-
(Springer, 2018)This study was focused on a by-product (i.e., belly muscle) resulting from the commercial processing of rainbow trout (Oncorhynchus mykiss). In it, n-3 long-chain polyunsaturated fatty acid (LCPUFA) concentrates were ...
-
(1989)This note presents measurements of the electric charge in a Nuclepore filter attained with a simple device able to detect induced charge in a metallic plate which is registered through a 610B KEITHLEY electrometer. A ...
-
(The Williams & Wilkins Co., 1975)Characterization of the metal-complexing ability of polyfunctional macromolecules through the determination of stability constants of their metalic complexes is discussed along with the validity of ascribing a relationship ...
-
(Sociedad Chilena de Cardiología y Cirugía Cardiovascular, 2001)La apoptosis junto a la paraptosis y la necrosis constituyen las principales formas de muerte celular conocidas hasta la fecha. La apoptosis se caracteriza por una disminución del volumen celular y formación de "cuerpos ...
-
(MACROMOLECULAR MATERIALS AND ENGINEERING 292(9): 1027-1034, 2007-09-14)Poly(propylene) (PP) composites were prepared by using eggshell (ES) as filler and their mechanical properties were compared with those using talc (TA) and calcium carbonate (CC) of different grain sizes (X-50). A decrease ...
-
(2013)Multi-walled carbon nanotubes (CNTs) are functionalized with itaconic acid (IA) and its derivative, monomethylitaconate (MMI), to prepare CNT/isotactic polypropylene (PP) composites. To promote dispersion and improved ...
-
(1975)The mechanical effects of heart contraction on coronary flow were studied in the dog heart by implanting vessels in the subendocardial and subepicardial layers of the left ventricular wall and perfusing them independently ...
-
(Oxford University Press, 1975)AUTHORS' SYNOPSIS: The mechanical effects of heart contraction on coronary flow were studied in the dog heart by implanting vessels in the subendocardial and subepicardial layers of the left ventricular wall and perfusing ...
-
(Blackwell Publishing Ltd, 2018)© 2018 The Protein Society Immunoglobulin Binding Protein (BiP) is a chaperone and molecular motor belonging to the Hsp70 family, involved in the regulation of important biological processes such as synthesis, folding and ...
-
(Nature, 2020)Knots are remarkable topological features in nature. The presence of knots in crystallographic structures of proteins have stimulated considerable research to determine the kinetic and thermodynamic consequences of threading ...

Mechanism of fluorophore quenching in a pre-fluorescent nitroxide probe: A theoretical illustration (Elsevier, 2014)The mechanism of fluorophore quenching in QT, a pre-fluorescent quinoline-TEMPO probe, is illustrated with the aid of a molecular-orbital analysis, offering a pictorial view of the process that takes place in the excited ...
-
(American Chemical Society, 2019)Experiments and theoretical calculations by density functional theory (DFT) have been carried out to examine a self-sensitized type I photooxidation of toluidine blue O (TBO+). This study attempts to build a connection ...
