Regulación de la dinámica y metabolismo mitocondrial por incretina GLP-1 en células de la línea A7r5
(Universidad de Chile, 2014)
El péptido similar a glucagón-1 (GLP-1) es una incretina secretada por las células intestinales. Su acción clásica es regular la respuesta secretoria de insulina por el páncreas. Sin embargo, recientemente se ha descrito ...
Oxidative stress as a novel target in pediatric sepsis management
(Elsevier, 2011)
Sepsis with secondary multisystem organ dysfunction syndrome is the leading cause of death
in the pediatric intensive care unit. Increased reactive oxygen species may influence circulating and
endothelial cells, contributing ...
Iron mediates neuritic tree collapse in mesencephalic neurons treated with 1-methyl-4-phenylpyridinium (MPP+)
(Springer, 2011)
Studies in post-mortem tissues of patients with
Parkinson’s disease (PD) and in mice treated with 6-hydroxydopamine
have shown a decrease in the length of
axon and dendrites of striatal neurons. However, the etiology
of ...
Spermatozoon ultrastructure in seven South American species of Tegula Lesson, 1835 (Mollusca: Vetigastropoda) and the phylogenetic implications for the subfamily Tegulinae
(INT SCIENCE SERVICES/BALABAN PUBLISHERS, 2008-12)
This study presents results of the examination of the ultrastructure of the spermatozoon of seven
South American species of Tegula using light and transmission electron microscopy. In all cases
the spermatozoa were of ...
Intracellular localization of Arabidopsis sulfurtransferases
(AMER SOC PLANT BIOLOGISTS, 2004-06)
Sulfurtransferases (Str) comprise a group of enzymes widely distributed in archaea, eubacteria, and eukaryota which catalyze the transfer of a sulfur atom from suitable sulfur donors to nucleophilic sulfur acceptors. In ...
Kupffer cell-dependent signaling in thyroid hormone calorigenesis: Possible applications for liver preconditioning
(2009)
Thyroid hormone (L-3,3′,5-triiodothyronine, T3) is important for the normal function of most tissues, with major actions on O2 consumption and metabolic rate. In the liver, these are due to (i) transcriptional activation ...
Metabolism of acetaldehyde by rat isolated aortic rings: Does endothelial tissue contribute to its extrahepatic metabolism?
(1993)
Acetaldehyde (AcH) metabolism in isolated aortic rings was studied by assessing in vitro-added AcH disappearing rate by head space gas chromatography. It was found that AcH was metabolized by aortic rings or by homogenates ...
The axonal endoplasmic reticulum: one organelle many functions in development, maintenance, and plasticity
(Wiley, 2018)
The endoplasmic reticulum (ER) is highly conserved in eukaryotes and neurons. Indeed, the localization of the organelle in axons has been known for nearly half a century. However, the relevance of the axonal ER is only ...
Estudo da produção de espécies reativas de oxigênio em subpopulações de monócitos de pacientes infectados pelo Plasmodium vivax
(Universidade Federal de Minas GeraisUFMG, 2015-11-12)
Malaria is considered one of the most prevalent diseases in the world. According with World Health Organization, malaria affects approximately 400 million people a year. Although the incidence of the disease has decreased ...
Intracellular localization of a photosensitizer and chloride channel activation in electrocytes
(Lima (Perú)PE, 2003-07)
The intracellular localization of a lipophilic alkyl long-chain tetraphenylporphyrin in electrocytes, Psammobatis extenta (Rajidae) is described. In contrast to the usual case, this porphyrin derivative was localized in ...
