OBJECTIVE: Dietary n-3 polyunsaturated fatty acids (PUFAs), especially eicosapentaenoic acids (EPA) and docosahexaenoic acid (DHA), are proved to be effective in obesity reduction. Microalgal oil (MO) is an important alternative source of n-3 PUFAs that effectively alleviates obesity. The aim of the present study was to explore the anti-obesity effects of microalgal oil from Schizochytrium sp. (SMO) and to compare the effects of 2 SMOs (SMO1 and SMO2) with different levels of purity of n-3 PUFAs on high fat diet (HFD)-induced obesity in male C57BL/6J mice...

Hibernation is a seasonally adaptive strategy that allows hibernators to live through extremely cold conditions. Despite the profound reduction of blood flow to the retinas, hibernation causes no lasting retinal injury. Instead, hibernators show an increased tolerance to ischemic insults during the hibernation period. To understand the molecular changes of the retinas in response to hibernation, we applied an integrative transcriptome and metabolome analysis to explore changes in gene expression and metabolites of 13-lined ground squirrel retinas during hibernation...

Intravenous administration of 2 g carnitine in every hemodialysis (3 times/week), for 8-10 months, reduced doses of darbepoetin alfa required to maintain adequate hemoglobin levels (10-11 g/dL) into 10% of the initial doses. There was also a significant increase in plasma transferrin saturation, increase in left ventricular ejection fraction, and decrease in plasma brain natriuretic peptides.

OBJECTIVE: The definition itself of subclinical hyperthyroidism (SHyper) and, therefore, the therapeutic approach to patients with SHyper still remains undefined and controversial. Therefore, the interest of finding a novel and alternative therapy for SHyper has caught the attention. An observational pilot study was performed to assess the effects of l-carnitine and selenium in the management of SHyper symptoms and endocrine profile in patients affected by this disease. PATIENTS AND METHODS: Patients with TSH levels between 0...

Isovaleric acidemia (IVA) is an autosomal recessive inborn error of leucine metabolism. It is caused by a deficiency in the mitochondrial isovaleryl-CoA dehydrogenase (IVD) enzyme. In this study, we investigated eight patients with IVA. The patients diagnoses were confirmed by urinary organic acid analysis and the blood C5-Carnitine value. A molecular genetic analysis of the IVD gene revealed nine different variants: five were missense variants (c.1193G>A; p. R398Q, c.1207T>A; p. Y403N, c.872C>T; p...

A long history of diabetes mellitus and increasing age are associated with the onset of diabetic neuropathy, a painful and highly disabling complication with a prevalence peaking at 50% among elderly diabetic patients. Acetyl-L-carnitine (ALC) is a molecule derived from the acetylation of carnitine in the mitochondria that has an essential role in energy production. It has recently been proposed as a therapy to improve the symptoms of diabetic neuropathy. ALC is widely distributed in mammalian tissues, including the brain, blood-brain barrier, brain neurons, and astrocytes...

Cardiac neuronal nitric oxide synthase (nNOS) is an important molecule that regulates intracellular Ca(2+) homeostasis and contractility of healthy and diseased hearts. Here, we examined the effects of nNOS on fatty acid (FA) regulation of left ventricular (LV) myocyte contraction in sham and angiotensin II (Ang II)-induced hypertensive (HTN) rats. Our results showed that palmitic acid (PA, 100 μM) increased the amplitudes of sarcomere shortening and intracellular ATP in sham but not in HTN despite oxygen consumption rate (OCR) was increased by PA in both groups...

Lipid accumulation is associated with reduced embryonic quality, causing limited survival after cryopreservation. Therefore, in the present study we aimed to reveal the effects of supplementation of a lipid reducing agent, l-carnitine and the removal of fatty acids during in vitro culture on the morphological as well as on the molecular level. To accomplish that, presumptive zygotes were cultured in 4 contrasting groups: namely SOFaa medium supplemented with BSA, (BSA), SOFaa medium supplemented with fatty acid free BSA (FAF), SOFaa medium supplemented with BSA as well as l-Carnitine (BSA + LC) and SOFaa medium concurrently supplemented with fatty acid free BSA and l-Carnitine (FAF + LC)...

BACKGROUND AND AIM: Oxidative stress plays an important role in platelet activation and endothelial dysfunction. Exogenous and endogenous reactive oxygen species are associated with platelet activation and vascular dysfunction. Antioxidants have been shown to attenuate oxidative stress and consequently endothelial dysfunction by preventing inflammation, regulating vascular tone, and promoting antiadhesive and antithrombotic properties. l-carnitine and its derivatives have been demonstrated to improve endothelial and platelet function against oxidative stress by several mechanisms, some of which cannot be found in other antioxidants...

The early-onset form of carnitine palmitoyltransferase (CPT) II deficiency has severe outcomes; patients typically die during the newborn period. We report a case of neonatal-onset CPT II deficiency with prolonged survival, exceeding 24 months. The patient was successfully treated by continuous hemodialysis (CHD), which enabled her to overcome repeated crises. We suggest that early intensive treatment, including CHD, is a key for prolonged survival in patients with neonatal-onset CPT II deficiency.

Major depressive disorder is a complex and common mental disease, for which the pathology has not been elucidated. The purpose of this study is to provide knowledge about the importance of mitochondrial dysfunction, dysregulated lipid metabolism and inflammation. Mitochondrial carnitine palmitoyl transferase 1a (CPT1a) is a key molecule involved in lipid metabolism and mutations in CPT1a causing reduced function is hypothesized to have a protective role in the development of depression. Moreover, CPT1a is found to be upregulated in suicide patients with history of depression...

Magnesium isoglycyrrhizinate as a hepatoprotective agent possesses immune modulation and anti-inflammation, and treats liver diseases. But its effects on immunological-inflammatory and metabolic profiles for metabolic syndrome with liver injury and underlying potential mechanisms are not fully understood. In this study, magnesium isoglycyrrhizinate alleviated liver inflammation and lipid accumulation in fructose-fed rats with metabolic syndrome. It also suppressed hepatic inflammatory signaling activation by reducing protein levels of phosphorylation of nuclear factor-kappa B p65 (p-NF-κB p65), inhibitor of nuclear factor kappa-B kinase α/β (p-IKKα/β) and inhibitor of NF-κB α (p-IκBα) as well as nucleotide-binding domain (NOD)-like receptor protein 3 (NLRP3), apoptosis-associated speck-like protein (ASC) and Caspase-1 in rats, being consistent with its reduction of interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α) and IL-6 levels...

Asparaginase is a chemotherapeutic agent that is commonly used in combination with other medications for the treatment of acute lymphoblastic leukemia. An adverse effect of asparaginase includes hepatotoxicity, which can lead to severe liver failure and death. Several reports have documented successful treatment of asparaginase-induced hepatotoxicity using levocarnitine (l-carnitine) and vitamin B complex. Herein, we report a patient with acute lymphoblastic leukemia that experienced acute liver injury following pegaspargase administration...

Ion suppression from the tissue matrix has a severe effect on the mass spectrometry imaging (MSI) of drugs. This problem hinders further applications of MSI in preclinical drug research and development. In this study, an in situ hydrogel conditioning method was developed to enhance the sensitivity of air-flow-assisted desorption electrospray ionization (AFADESI)-MSI. Instead of the traditional wash-up or digestion treatment in solvent, this method used a solid phase hydrogel to "wash" tissue sections. It was demonstrated that this in situ hydrogel conditioning method improve the drug signal by as much as 2- to 25-folds in MSI, especially for hydrophobic compounds...

Carnitine palmitoyltransferase II (CPT-2) deficiency, an autosomal recessive disorder of fatty acid oxidation, can be detected by newborn screening using tandem mass spectrometry (TMS). Our case was a boy born at 38 weeks and 6 days of gestation via normal vaginal delivery; his elder sister was affected with CPT-2 deficiency. Acylcarnitine (AC) was analyzed in both dried blood spots (DBS) and serum 2 h after birth to determine whether the boy was also affected. His C16 and C18:1 AC levels in DBS were in the normal range, while his serum long-chain AC levels were marginally increased but lower than those of his sister...

Nitric oxide (NO), generated from L-arginine by three different isoforms of nitric oxide synthase (NOS), is a pleiotropic factor to regulate physiological functions in almost every organ and tissue. Each knockout mouse of iNOS or eNOS has been used to suggest that NO has a crucial role in liver regeneration after partial hepatectomy (PH), for NO may inhibit caspase 3 activity and is required for EGFR signaling. In previous reports, defective mitochondrial β-oxidation was observed in eNOS KO mice, and hepatic steatosis was often correlated to deficient liver regeneration, so we focused on metabolic perspective and hypothesized that NO depletion in PH mice would affect hepatocytic lipolysis and impair hepatocytes proliferation...

Hormonal signals help to maintain glucose and lipid homeostasis in the liver during periods of fasting. Glucagon, a pancreas-derived hormone induced by fasting, promotes gluconeogenesis through induction of intracellular cAMP production. Glucagon also stimulates hepatic fatty acid oxidation but the underlying mechanism is poorly characterized. Here we reported that following the acute induction of gluconeogenic genes Glucose 6 phosphatase (G6Pase) and Phosphoenolpyruvate carboxykinase (Pepck) expression through CREB, glucagon triggers a second delayed phase of fatty acid oxidation genes Acyl-coenzyme A oxidase (Aox) and Carnitine palmitoyltransferase 1a (Cpt1a) expression via extracellular cAMP...
