Protective effect of trimetazidine on myocardial mitochondrial function in an e...

Trimetazidine is an anti-ischemic drug whose cytoprotective mechanisms are not yet fully understood (but until now mainly related to the trimetazidine-induced "metabolic shift" from lipid beta-oxidation to glucose aerobic oxidation). We studied the effect of trimetazidine on the mitochondrial function of ischemic Wistar rat hearts perfused with glucose, using a model of ex-vivo perfusion (Langendorff system). W...

Vantagens Na Utilização do Carvedilol Em Relação Ao Propranolol Na Protecção da...

BACKGROUND: Carvedilol is a neurohormonal antagonist of multiple action which is used in clinical practice for the treatment of congestive heart failure, mild to moderate hypertension and myocardial infarction. Previous results from our group have demonstrated that one of the main targets for the protective effect of carvedilol is the cardiac mitochondrial network. In-this work, we compare the effect of carvedi...

Histological changes and impairment of liver mitochondrial bioenergetics after ...

This study was designed to evaluate the effects of long-term treatment with alpha-naphthyl-isothiocyanate (ANIT) on liver histology and at the mitochondrial bioenergetic level. Since, ANIT has been used as a cholestatic agent and it has been pointed out that an impairment of mitochondrial function is a cause of hepatocyte dysfunction leading to cholestatic liver injury, serum markers of liver injury were measur...

Carvedilol: Relação Entre A Actividade Antioxidante e Inibição da Transição de ...

OBJECTIVES: The mitochondrial permeability transition (MPT) is an event related to severe oxidative stress (for example, during myocardial ischemia and reperfusion) and excessive mitochondrial calcium accumulation, also being implicated in cell death. In this study, we compared the effect of carvedilol on the cardiac MPT induced by calcium and phosphate (Ca/Pi) and calcium/carboxyatractyloside (Ca/Catr). Oxidat...

O Piruvato Melhora A Energética Mitocondrial Num Modelo Animal Ex-vivo de Isque...

Pyruvate is an energy substrate with known cardioprotective activity. We know now that this is due not only to its antioxidant activity, but also to its reduction of intracellular acidosis, modulation of intracytosolic calcium and improvement of cardiomyocyte contractility. However, the role of cardiac mitochondria in such positive effects has only recently begun to be understood and the exact mechanisms of the...

Carvedilol improves energy production during acute global myocardial ischaemia

Cardiac mitochondria may become dysfunctional during ischaemia, thus compromising cardiomyocyte function. Carvedilol is an alpha(1)/beta-adrenoceptor antagonist with antioxidant, neuroprotective, cardioprotective and vascularprotective properties, and is used to treat hypertension, myocardial ischaemia and congestive heart failure. However, its impact on mitochondrial function during acute prolonged ischaemia i...

Impacto do Carvedilol Sobre O Dano Mitocondrial Induzido Por Hipoxantina/xantin...

OBJECTIVES: The cardioprotective effects of carvedilol (CV) may be explained in part by interactions with heart mitochondria. The objective of this work was to study the protection afforded by CV against oxidative stress induced in isolated heart mitochondria by hypoxanthine and xanthine oxidase (HX/XO), a well-known source of reactive oxygen species (ROS) in the cardiovascular system. METHODS: Mitochondria wer...

Familial camptodactyly

Camptodactyly is a permanent flexion deformity at the interphalangeal joints, usually at the proximal, interphalangeal joints. It is by far most commonly encountered in the little finger, but it can occur in any of the others, and may be associated with a deformity in the little finger or not. It is usually bilateral. It can also appear in the toes, the second toe being the most frequently affected. This deform...
