Introduction: The aim of this study was to investigate the effect of aerobic training and consumption of L-carnitine supplements on HMG-CoA reductase and low density lipoprotein receptor (LDL-R) in the liver of male Wistar rats toxicated by boldenone. Materials and methods: In this clinical study, 30 male Wistar rats aged 12 weeks (weight 195±7.94g) were randomly divided into five groups: cont...

Carnitine, gamma-trimethyl-beta-hydroxybutyrobetaine, is a small molecule widely present in all cells from prokaryotic to eukaryotic. It is an important element in the beta-oxidation of fatty acids. A lack of carnitine in hemodialysis patients is caused by insufficient carnitine synthesis and particularly by the loss through dialytic membranes, leading in some patients to carnitine depletion wi...

Two objectives of this study were to investigate the weekly change in plasma L-carnitine concentration during the 28 day suckling period and to determine the relative mRNA expression level of a L-carnitine transporter, OCTN2, in porcine mammary tissue at early and peak lactation. The results showed that the L-carnitine concentration of piglets after giving birth was 3.94±0.13 mg/L. L-carnitine ...

BACKGROUND Depression is highly prevalent in uremic patients undergoing hemodialysis (HD). We previously found that low free-carnitine levels are associated with depression severity in male patients undergoing HD. However, whether L-carnitine supplementation improves the depression state in male patients undergoing HD remains unclear. METHODS Sixteen male patients undergoing HD were orally ad...

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...

In recent years, l-carnitine has been used increasingly as a supplement in livestock animals. The present review gives an overview of the effects of dietary l-carnitine supplementation on the reproductive performance of sows. Results concerning the effect of l-carnitine supplementation during pregnancy on litter sizes are controversial. There are some studies reporting an increased number of pi...

Early feed restriction of lambs promotes a permanent mitochondrial dysfunction that impairs efficiency along the whole life. Dietary L-carnitine, compound plays an essential role in energy metabolism transferring long-chain fatty acids to mitochondria for subsequent β-oxidation, has demonstrated positive effects (e.g., improved markers or muscle/heart function) early restricted lambs. The purpo...

l-Carnitine is a vitamin-like amino acid derivative, which is an essential factor in fatty acid metabolism as acyltransferase cofactor and in energy production processes, such as interconversion in the mechanisms of regulation of cetogenesis and termogenesis, and it is also used in the therapy of primary and secondary deficiency, and in other diseases. The determination of carnitine and acyl-ca...

This study has been initiated to investigate whether endogenous carnitine depletion and/or carnitine deficiency is a risk factor during development of cisplatin (CDDP)-induced cardiomyopathy and if so, whether carnitine supplementation by propionyl-L-carnitine (PLC) could offer protection against this toxicity. To achieve the ultimate goal of this study, a total of 60 adult male Wistar albino r...

an experiment was conducted to study the effects of soybean, linseed and sunflower oil (various sources of fatty acids) with and without l-carnitine supplements (0 and 50 mg kg-1) on performance, blood biochemical parameters and carcass traits of japanese quail. one hundred and ninety-two of 7-day old female japanese quail were randomly assigned to 6 dietary treatments with 4 replicates and fed...
