Lissi Gervaso, Eduardo A.; Salim-Hanna, Marta; Fauré, M.; Videla Cabrera, Luis (Informa Healthcare, 1991)1. 2,2'Azo-bis-amidinopropane (ABAP) thermal decomposition produces free radicals that initiate the lipid peroxidation of erythrocyte ghost membranes. 2. Addition of 6-n-propyl-2-thiouracil decreases the rate of the process, ...

Tapia Opazo, Gladys; Fernández Arancibia, Virginia; Pino, César; Ardiles, Rodrigo; Videla Cabrera, Luis (ELSEVIER, 2006-05-01)Recently, we reported that 3,3,5-triiodothyronine (T-3) induces the expression of redox-sensitive genes as a nongenomic mechanism of T3 action. In this study, we show that T3 administration to rats (daily doses of 0. 1 ...

Videla Cabrera, Luis; Valenzuela Bonomo, Carlos (1982)Data reviewed here indicate that acute and chronic ethanol ingestion induce a decrease in the concentration of GSH and an increase in lipoperoxidation in the liver both in experimental animals and in man, changes that are ...

Dossi, Camila G.; González Mañán, Daniel Alonso; Romero, Nalda; Silva, David; Videla Cabrera, Luis; Tapia Opazo, Gladys (Royal Society of Chemistry, 2018)© The Royal Society of Chemistry. Ischemia-reperfusion (IR) is a deleterious condition associated with liver transplantation or resection that involves pro-oxidant and pro-inflammatory mechanisms. Considering that Rosa ...

Speisky Cosoy, Hernán; Cassels Niven, Bruce; Lissi Gervaso, Eduardo A.; Videla Cabrera, Luis (Pergamon Press, 1990-11-30)Boldine, in low micromolar concentrations, was able to prevent brain bomogenate autooxidatíon, the 2,2'·uobis(2·amidinopropane)(AAP)·induced Iipid peroxidation of red cell plasma rnembranes, and the AAP·induced inactivation ...

Fernández Arancibia, Virginia; Videla Cabrera, Luis (1996)Aerobic life is characterized by a steady generation of reactive oxygen species balanced by a similar rate of their consumption by antioxidants. To maintain homeostasis, there is a requirement for the continuous regeneration ...

Arisi, Ana Carolina M.; Kiyoko, Simizu; Marisa, Kogake; Barny, Afonso C.D.; Silva, Marcia A.S.; Barros, Silvia B.M.; Boveris, Alberto; Videla Cabrera, Luis; Junqueira, Virginia (1994)Oxidative stress-related parameters in rat brain and liver were evaluated following acute (60 mg/kg i.p., 2 and 24 h after dosing) or short-term (1000 ppm in the diet for 90 days) lindane administration. Both treatments ...

Fernández Arancibia, Virginia; Tapia Opazo, Gladys; Varela, Patricia; Gaete González, Leonardo; Vera, Gemma; Mora, Catalina; Vial, María T.; Videla Cabrera, Luis (ELSEVIER, 2008-05-01)Hepatic ischemia-reperfusion (R) injury, a major clinical drawback during surgery, is abolished by L-3,3',5-triiodothyronine (T-3) administration. Considering that the triggering mechanisms are unknown, the aim of this ...

Causal role of oxidative stress in unfolded protein response development in the hyperthyroid state Videla Cabrera, Luis; Fernández Arancibia, Virginia; Cornejo, Pamela; Vargas, Romina; Carrasco, Juan; Fernández, Javier; Varela Figueroa, Nelson (Elsevier, 2015)L-3,3',5-Triiodothyronine (T-3) induced liver oxidative stress underlies significant protein oxidation, which may trigger the unfolded protein response (UPR). Administration of daily doses of 0.1 mg T-3 for three consecutive ...

Cornejo, Pamela; Varela, Patricia; Videla Cabrera, Luis; Fernández Arancibia, Virginia (ACADEMIC PRESS INC ELSEVIER SCIENCE, 2005-08)Iron is an essential micronutrient promoting oxidative stress in the liver of overloaded animals and human, which may trigger the expression of redox-sensitive genes. We have tested the hypothesis that chronic iron overload ...
-
Valenzuela Báez, Rodrigo; Videla Cabrera, Luis (Elsevier, 2018-06)Normal liver function includes a number of metabolic processes, secretion of cellular mediators and its role in immunobiology; these require a high energy supply, which is further enhanced under adverse conditions triggering ...

Videla Cabrera, Luis; Troncoso, P.; Arisi, A. C.M.; Junqueira, Virginia (1997)1. Twenty-four hours after lindane exposure (5-60 mg/kg) a dose-dependent increase in the serum and hepatic levels of the insecticide was observed. Both the basal rate of O2 consumption and the sinusoidal efflux of lactate ...
