Background: Ventricular septal defect (VSD) and Atrial (ASD) are the most common congenital heart disease (CHD). This study aimed to improve of health status, quality life, morbidity mortality pediatrics patient with ASDs. Methods: was a cohort carried out at Pediatric Cardiology Unit Zagazig University hospitals during period from October 2019 2020 Included 30 children up 2 years age were foll...

Previous studies from this laboratory and by Wittels and Bressler have suggested that myocardial carnitine depletion and an accompanying decrease in fatty acid oxidation may contribute to the myocardial disease associated with diphtheria. In addition, administration of carnitine was found to prolong survival of diphtheritic guinea pigs and improve ventricular function in diphtheritic dogs. The ...

Carnitine and its derivatives have recently been shown to protect cardiac metabolism and function in ischemic heart disease and other clinical conditions of myocardial ischemia. Potential mechanisms of this effect include an increase in glucose metabolism, a reduction of toxic effects of long-chain acyl-CoA and acyl-carnitine in myocytes, an increase in coronary blood flow and anti-arrhythmic e...

A wide range of morphological and biochemical changes occur in the central nervous system with increasing age. L-carnitine, a naturally occurring compound, plays a vital role in fatty acid transport across the mitochondrial membrane. L-carnitine (300 mg/kg body wt/day) was administered intraperitoneally to young and old male Wistar rats for 7, 14, and 21 days. Carnitine, dopamine, epinephrine, ...

  Twelve weeks of daily l-carnitine and carbohydrate feeding in humans increases skeletal muscle total carnitine content, and prevents body mass accrual associated with carbohydrate feeding alone. Here we determined the influence of L-carnitine and carbohydrate feeding on energy metabolism, body fat mass and muscle expression of fuel metabolism genes. Twelve males exercised at 50% maximal oxyge...

BACKGROUND AND AIMS Atherosclerotic cardiovascular disease is the most common cause of mortality in patients with end-stage kidney disease. Chronic kidney disease patients often exhibit a deficiency in L-carnitine due to loss during hemodialysis (HD). We studied the effects of L-carnitine supplementation on brachial-ankle pulse wave velocity (baPWV), a marker of atherosclerosis, in HD patients....

Carnitine is a conditionally essential nutrient that plays a vital role in energy production and fatty acid metabolism. Vegetarians possess a greater bioavailability than meat eaters. Distinct deficiencies arise either from genetic mutation of carnitine transporters or in association with other disorders such as liver or kidney disease. Carnitine deficiency occurs in aberrations of carnitine re...

BACKGROUND It has been shown that plasma carnitine concentrations decrease markedly during gestation. A recent study performed with a low number of subjects suggested that this effect could be due to a low iron status which leads to an impairment of carnitine synthesis. The present study aimed to confirm this finding in a greater number of subjects. It was moreover intended to find out whether ...

Rat liver, kidney, pancreas, and small intestine have enzymes which hydrolyze fatty acid esters of carnitine. The liver enzyme, located in the microsomal fraction, was solubilized by sonic disruption and purified l&fold by diethylaminoethyl cellulose chromatography and Sephadex gel filtration. The purified enzyme sedimented in the ultracentrifuge as a single protein with an szo+, of 4.5 S. The ...

We kinetically analyzed the disposition of L-carnitine of juvenile visceral steatosis (JVS) mice compared with that of normal mice to elucidate the mechanism of the systemic L-carnitine deficiency of JVS mice. There were significant differences in the plasma concentration-time course of total radioactive carnitine (L-[H]carnitine, [acetyl-H]carnitine, and other [acyl-H]carnitines) between norma...
