Signal transduction and gene expression regulated by calcium release from internal stores in excitable cells
(SOCIEDAD BIOLOGIA CHILE, 2004)
Calcium regulation of several transcription factors involves different calcium-dependent signaling cascades and engages cytoplasmic as well as nuclear calcium signals. The study of the specific sources of calcium signals ...
Quaternized chitosan as support for the assembly of gold nanoparticles and glucose oxidase: Physicochemical characterization of the platform and evaluation of its biocatalytic activity
(ELSEVIER, 2011-01-01)
We report for the first time the use of quaternized chitosan (QCHI) for the immobilization of gold nanopartides (NP) and glucose oxidase (GOD), the characterization of the resulting platform and its biocatalytic activity ...
G2 checkpoint-dependent DNA repair and its response to catalase in Down syndrome and control lymphocyte cultures
(2007)
The amount of DNA lesions repaired in G2 and also G2 timing are controlled by the DNA damage-dependent checkpoint. Down syndrome (DS) lymphocytes showed twice as much constitutive DNA damage in G2 than control ones, when ...
Two-phase kinetic model for epoxidation of soybean oil
(Universidad Nacional de Colombia - Facultad de Ingeniería, 2010)
A two-phase kinetic model was implemented for analyzing conventional epoxidation, using a percarboxylic acid gene- rated in situ through adding hydrogen peroxide in a two-phase system having a homogeneous catalyst. Data ...
Rapid screening fluorescence method applied to detection and quantitation of paralytic shellfish toxins in invertebrate marine vectors
(Taylor and Francis Ltd., 2019)
A rapid screening method is described for the determination of paralytic shellfish toxins (PST), in fresh marine vectors (bivalves and gastropods), at levels ranging from 0.05 to 5.0 mg STX-eq kg−1. PST are extracted from ...
Banana Moko disease management with resistance inducers and chlorine dioxide
(Universidad Nacional de Colombia, 2015-05-01)
The plant disease Moko, caused by Ralstonia solanacearum, is the most important bacterial disease in banana and plantain crops worldwide. In the present study, chlorine dioxide and seven resistance inducers in banana plants ...

(Universidad de los Llanos, 2013-07-01)
titulo en ingles: Determination of adulterants in stockpiled crude milks from cheese processors in Montería (Cordoba)Titulo en portugues: Determination of adulterants in stockpiled crude milks from cheese processors in ...
Evaluation of different methods for efficient extraction of hemicelluloses leaves and tops of sugarcane
(Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas, 2018)
En Colombia se producen alrededor de 9 millones de toneladas de residuos de la cosecha de la caña de azúcar por hectárea cada año, que no han sido valorizados hacia ningún tipo de producto. Es necesario conocer su composición, ...
Insulin-Dependent H2O2 Production Is Higher in Muscle Fibers of Mice Fed with a High-Fat Diet
(2013)
Insulin resistance is defined as a reduced ability of insulin to stimulate glucose
utilization. C57BL/6 mice fed with a high-fat diet (HFD) are a model of insulin resistance.
In skeletal muscle, hydrogen peroxide (H2O2) ...
TNF-alpha increases production of reactive oxygen species through Cdk5 activation in nociceptive neurons
(Frontiers Media SA, 2018)
The participation of reactive oxygen species (ROS) generated by NOX1 and NOX2/NADPH oxidase has been documented during inflammatory pain. However, the molecular mechanism involved in their activation is not fully understood. ...
