OBJECTIVES Malnutrition is an independent predictor of death in idiopathic dilated cardiomyopathy. An analysis was performed of the impact of L-carnitine supplementation on the nutritional status and echocardiogram parameters of children with idiopathic dilated cardiomyopathy. METHODS This was an open label cohort of 11 patients who received L-carnitine (100 mg/kg/day) plus the conventional m...

PURPOSE Hypoxic-ischemic encephalopathy is an important cause of neonatal mortality, as this brain injury disrupts normal mitochondrial respiratory activity. Carnitine plays an essential role in mitochondrial fatty acid transport and modulates excess acyl coenzyme A levels. In this study, we investigated whether treatment of primary cultures of rat cortical neurons with L-carnitine was able to ...

BACKGROUND Atherosclerosis is the leading cause of death in hemodialysis patients. These patients are also very prone to L-carnitine deficiency due to kidney disease. In this clinical trial, we investigated the effect of oral L-carnitine on endothelial function of these patients. MATERIALS AND METHODS [corrected] We studied 31 adult chronic hemodialysis patients in our center and divided them...

Successful cryopreservation for human spermatozoa markedly influences the reproductive outcomes of assisted reproductive technologies. But in spite of its usefulness, cryopreservation significantly decreases sperm quality. l-carnitine has been found to improve the quality of spermatozoa in selected cases with male infertility. Here, we examined the efficacy of l-carnitine in improving sperm mot...

OBJECTIVE Plasma acts as a good indicator of oxidative stress in blood. L-Carnitine is an antioxidant that reduces metabolic stress in cells, thereby providing a protective effect against oxidative stress (OS). L-Carnitine as an additive in storage has not been explored. Thus, this study attempts to analyze the role of L-carnitine in blood storage solution, citrate phosphate dextrose adenine (C...

Several studies have demonstrated that L-carnitine exhibits neuroprotective effects on injured sciatic nerve of rats with diabetes mellitus. It is hypothesized that L-carnitine exhibits neuroprotective effects on injured sciatic nerve of rats. Rat sciatic nerve was crush injured by a forceps and exhibited degenerative changes. After intragastric administration of 50 and 100 mg/kg L-carnitine fo...

This experimental was study designed to examine the efficacy of L-carnitine in preventing reperfusion injury following testicular torsion. We aimed to evaluate the effects of L-carnitine, administered during the reperfusion period, on the torsed and contralateral non-torsed testes in cases of unilateral testicular torsion in rats. This experimental study was performed in the research laboratory...

The purpose of this study was to evaluate the effects of L-carnitine fed during gestation and lactation on reproductive performance of sows and litter performance. A total of 57 multiparous TLRI Black Pig No.1 (TBP) sows were used in this experiment. Pregnant sows were provided daily 150 ppm L-carnitine from day 91 of pregnancy to farrowing and 250 ppm/d L-carnitine provided postfarrowing throu...

Cryopreservation of epididymal sperm is an effective technique to preserve genetic materials of domestic cats and wild felids when they unexpectedly die. However, this technique inevitably causes detrimental changes of cryopreserved-thawed spermatozoa, for example, by physical damage and excessive oxidative stress. L-carnitine is an antioxidant that has been used to improve sperm motility in hu...

BACKGROUND Frailty is a biological syndrome of decreased reserve and resistance to stressors due to decline in multiple physiological systems. Amino acid deficiency, including L-carnitine, has been proposed to be associated with its pathophysiology. Nevertheless, the efficacy of L-carnitine supplementation on frailty status has not been documented. Thus, this study aimed to determine the effect...
