Data on the functionalities of L-carnitine on obesity, diabetes, and as an ergogenic aid are summarized as follows: Obesity: Total lipid, triglyceride, and total protein increased during the 3T3-L1 cell differentiation. However, nonesterified carnitine (NEC), acid-soluble acylcarnitine (ASAC), and acid-insoluble acylcarnitine (AIAC) concentrations were lower in the differentiated 3T3-L1 cells. ...

background: l-carnitine may prevent the incidence of aki by its antioxidant effects and improving circulation in ischemic conditions. the goal of this trial was to evaluate the impact of l-carnitine on contrast-induced nephropathy in patients undergoing elective pci. methods: totally, the patients were randomly allocated to 2 groups. the treatment group received 1 g of l-carnitine orally 3 time...

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...

BACKGROUND The conditionally essential nutrient, L-carnitine, plays a critical role in a number of physiological processes vital to normal neonatal growth and development. We conducted a systematic evaluation of the developmental changes in key L-carnitine homeostasis mechanisms in the postnatal rat to better understand the interrelationship between these pathways and their correlation to ontog...

BACKGROUND Anaemia is a common complication associated with haemodialysis and is usually managed by treatment with recombinant human erythropoietin (rHuEPO). However, many patients remain hyporesponsive to rHuEPO treatment despite adequate iron therapy. The effect of L-carnitine administration on rHuEPO dose and/or haematocrit in haemodialysis patients has been previously reported with equivoca...

Maternofetal transport of l-carnitine, a molecule that shuttles long-chain fatty acids to the mitochondria for oxidation, is thought to be important in preparing the fetus for its lipid-rich postnatal milk diet. Using brush-border membrane (BBM) vesicles from human term placentas, we showed that l-carnitine uptake was sodium and temperature dependent, showed high affinity for carnitine (apparen...

Objective: The use of non-enzymatic antioxidants in food supplements and proper exercise can have a positive effect on decreasing oxidative stress by free radical hunting. The purpose of this study was to investigate the effect of aerobic training and L-carnitine supplementation on some of the oxidative stress factors in the liver of diabetic rats. Materials and Methods: In this experimental s...

Background:  The aim of the study was to compare the radioprotective efficacy in the kidney of L-carnitine to that of amifostine. Materials and Methods: Thirty three-month-old Wistar albino rats were randomly assigned to four groups: Group 1 (Control); Group 2 (Irradiation alone); Group 3 (amifostine plus irradiation); and Group 4 (L-carnitine before irradiation). The rats in Groups 2, 3, ...
