Fatty acid oxidation in macrophages is thought to regulate inflammatory status and insulin-sensitivity. An important unanswered question in this field is whether carnitine acetyl-transferase (CrAT) that regulates fatty acid oxidation and mitochondrial acetyl-CoA balance is required to integrate
OBJECTIVE
Obesity is an important worldwide public health problem and considered a disease of chronic low-grade inflammation. The aim of this study was to evaluate the effect of L-carnitine supplementation in comparison with moderate aerobic exercise training on serum inflammatory parameters in
Because carnitine has been shown to decrease oxidative stress and improve endothelial cell functioning, we examined the effects of carnitine supplementation on postprandial flow-mediated dilation (FMD) and circulating biomarkers of inflammation and oxidative stress after a high-fat meal. A
We have investigated the gross, microscopic and molecular effects of carnitine deficiency in the neonatal gut using a mouse model with a loss-of-function mutation in the OCTN2 (SLC22A5) carnitine transporter. The tissue carnitine content of neonatal homozygous (OCTN2(-/-)) mouse small intestine was
BACKGROUND
A prospective randomized study was performed to investigate the validity of intravenous carnitine administration during postoperative parenteral nutrition (PN) with lipid emulsion.
METHODS
Patients undergoing surgery for gastric or colorectal cancer were enrolled in the study and were
Objective: l-Carnitine has been suggested as a potential nutrient that alleviates the oxidative and inflammatory damages of coronary artery disease (CAD), but the results of the previous studies of the importance of this supplementation
This study was performed to evaluate the effects of carnitine administration on carotid intima-media thickness (CIMT) and inflammatory markers in women with polycystic ovary syndrome (PCOS).Methods
This randomized, double-blind, placebo-controlled
BACKGROUND
It is known that L-carnitine is a cofactor in the transport of fatty acids across the inner mitochondrial membrane for beta-oxidation. However, L-carnitine is an antioxidant compound widely used for the treatment of deficits in functions due to the aging process.
OBJECTIVE
The purpose of
BACKGROUND
Heart failure (HF) is accompanied by elevated levels of pro-inflammatory cytokines. Skeletal muscle myopathy with atrophy of fibres, decreased oxidative metabolism and preferential synthesis of fast myosin heavy chains (MHCs) occurs, which contributes to the worsening of symptoms.
After finding relatively large amounts of carnitine in polymorphonuclear leukocytes and mononuclear cells from healthy subjects, we studied carnitine status in these cells and plasma from 20 patients with inflammatory disorders subsequent to multiple trauma and (or) head injury. The nonesterified
Carnitine uptake into tissues is mediated mainly by the novel organic cation transporter 2 (OCTN2), whose expression is upregulated in the liver of early-lactating dairy cows. It has been shown recently that pro-inflammatory cytokines, including tumor necrosis factor α (TNFα), stimulate OCTN2
Carnitine is essential for transport of long-chain fatty acids into mitochondria for their subsequent beta-oxidation, but its role in the gastrointestinal tract has not been well described. Recently several genetic epidemiologic studies have shown strong association between mutations in carnitine
Carnitine in erythrocytes and leucocytes represents a small but essential part of the cellular carnitine pool. It was the objective of this study to document the changes of blood cell carnitine concentrations in disease entities with an enhanced cellular metabolism during acute and chronic
The intestinal barrier is one of the most dynamic surfaces of the body. It is here where a single layer of epithelial cells mediates the intricate encounters that occur between the host's immune system and a multitude of potential threats present in the intestinal lumen. Several key factors play an
OBJECTIVE
To analyze the levels of free carnitine and carnitine esters in the muscles of patients with inflammatory myopathies.
METHODS
Six men and 7 women with inflammatory myopathy and 25 age-matched healthy controls were studied. Free carnitine and carnitine esters in muscle homogenates were
