Gestating sows (n = 44; parity = 2.0; BW = 208 kg) were used to determine the effects of dietary L-carnitine and Cr picolinate (CrP) on daily blood hormone and metabolite profiles. Diets were formulated as a 2 x 2 factorial with L-carnitine (0 or 50 ppm) and CrP (0 or 200 ppb) and were fed from breeding through gestation, lactation, and 28 d into the subsequent gestation, at which time blood co...

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, ...

BACKGROUND L(-)-carnitine production has been widely studied because of its beneficial properties on various diseases and dysfunctions. Enterobacteria possess a specific biotransformation pathway which can be used for the enantioselective production of L(-)-carnitine. Although bioprocesses catalyzed by enzymes or whole cells can overcome the lack of enantioselectivity of chemical methods, curre...

OBJECTIVES This study was performed to identify a target population of claudicants for propionyl-L-carnitine treatment. BACKGROUND Previous studies suggest that the efficacy of propionyl-L-carnitine in intermittent claudication is greater in patients with severe functional impairment than in those with mild walking disability. METHODS After run-in, 485 claudicant patients were randomized to...

Atherosclerosis is a condition caused by lipid build-up and inflammation in the arteries, so hyperlipidemia is the major reason for atherosclerosis. Testis was found to be negatively affected by hyperlipidemia which leads to its impaired functions. Vitamin E and l-carnitine have well-known lipid-lowering and antioxidative activities. Triton WR 1339 is a non-ionic detergent, which induces severe...

Levo-carnitine (L-carnitine) facilitates the transport of long chain fatty acyl co-enzyme A (CoA) across the mitochondrial membrane for eventual oxidation and energy production. Carnitine deficiency results in free fatty acid accumulation and contributes to cardiovascular complications in experimental diabetes. In this condition, oral carnitine supplementation provides cardio-protection by its ...

BACKGROUND This study examined whether carnitine deficiency is a risk factor and should be viewed as a mechanism during the development of gentamicin (GM)-induced ARF as well as exploring if carnitine supplementation could offer protection against this toxicity. METHODS Adult male Wistar albino rats were assigned to one of six treatment groups: group 1 (control) rats were given daily intraper...

effect of l-carnitine and butyric acid on the performance and immune responses of 192 broiler chickens (ross 308) was investigated with three levels of l-carnitine (zero, 125 and 250 mg/kg) and two levels of butyric acid (2 g/kg) in a 2×3 factorial arrangement based on randomized complete block design with 6 dietary treatments, four replicates and eight birds per each. broilers fed basal diet p...

Background Recently, supplementation of L-carnitine to obese rats was found to improve the carnitine status and to counteract an obesity-induced muscle fiber transition from type I to type II. However, it has not been resolved if the change of muscle fiber distribution induced in obese rats and the restoration of the "normal" muscle fiber distribution, which is found in lean rats, in obese rats...

BACKGROUND L-carnitine supplementation has been suggested to show several favorable effects on patients with liver cirrhosis (LC). However, there have been no reports regarding the effect of L-carnitine on energy metabolism in patients with LC using indirect calorimetry which is a well-established method for assessing the degree of liver malnutrition. We examined the effect of L-carnitine in pa...
