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...

Skeletal muscle wasting, associated with aging, may be regulated by the inflammatory cytokines as well as by insulin-like growth factor 1 (IGF-1). l-carnitine possesses anti-inflammatory properties and increases plasma IGF-1 concentration, leading to the regulation of the genes responsible for protein catabolism and anabolism. The purpose of the present study was to evaluate the effect of a 24-...

AIMS To evaluate the effect of L-carnitine supplementation (25 mg/kg/d) on the growth and incidence of hypoglycaemia in preterm infants. METHODS A double blind, placebo controlled randomised trial, stratified for gestational age, was conducted of 86 preterm infants between 28 and 34 gestational weeks. The median gestational ages in the carnitine group and placebo groups were 30.7 weeks (range...

The main objective for the present research was to assess the effect of cyclic starvation and L- carnitine supplementation on growth (body final weight, hepatosomatic index (HSI), daily growth rate (DGI), feed conversion ratio (FCR) and voluntary feed intake (VFI)), body composition (crude protein, crude lipid, ash and moisture), biochemical (plasma total protein, glucose, cholesterol, triglyce...

To investigate the relationship between polyol pathway hyperactivity and altered carnitine metabolism in the pathogenesis of diabetic neuropathy, the effects of an aldose reductase inhibitor, [5-(3-thienyl) tetrazol-1-yl]acetic acid (TAT), and a carnitine analog, acetyl-L-carnitine (ALC), on neural functions and biochemistry and hemodynamic factors were compared in streptozotocin-diabetic rats....

Objective(s): This study intended to investigate the effects of Ginsenoside-Rbl (Gs-Rbl) on fatty acid β-oxidation (FAO) in rat failing heart and to identify potential mechanisms of Gs-Rbl improving heart failure (HF) by FAO pathway dependent on AMP-activated protein kinase (AMPK). Materials and Methods: Rats with chronic HF, induced by adriamycin (Adr), were randomly grouped into 7 groups. Gs-...

Objectives: L-carnitine has been used as therapy in hemodialysis patients for many years. When HCV was present, higher rates of patient mortality displayed. However, no study is concerned with the synergistic effect of L-carnitine and HCV. The purpose of this study was to investigate the effect of L-carnitine on the markers of DNA damage and oxidative stress in maintenance hemodialysis patients...

BACKGROUND Chronic alcohol intake exerts myocardial damage en route to the development of alcoholic cardiomyopathy (ACM), although the precise pathogenesis of ACM is unknown. Carnitine is known to participate in the regulation of metabolism in a number of heart diseases. This study was designed to examine the interplay between myocardial metabolism and carnitine in the development of ACM. MAT...

To determine whether accumulation of long-chain acyl carnitine contributes to electrophysiological abnormalities induced by hypoxia, we characterized effects of normoxic and hypoxic perfusion on the subcellular distribution of endogenous long-chain acyl carnitine and transmembrane potentials of cultured rat neonatal myocytes. Hypoxia increased long-chain acyl carnitine more than 5-fold. Sodium ...
