The increasing death rate caused by drug overdose points to an urgent demand for the development of novel detoxification therapy. In an attempt to detoxify tricyclic antidepressant overdose, we prepared a lipid nanoemulsion, called squarticles, as the nanoantidote. Squalene was the major lipid matrix of the squarticles. Here, we present the animal study to investigate both the pharmacokinetic and pharmacodynamic effects of squarticles on amitriptyline intoxication. The anionic and cationic squarticles had average diameters of 97 and 122 nm, respectively...

STUDY QUESTION: Does the use of a vascular contrast agent facilitate earlier detection of maternal flow to the placental intervillous space (IVS) in the first trimester of pregnancy? SUMMARY ANSWER: Microvascular filling of the IVS was demonstrated by contrast-enhanced ultrasound from 6 weeks of gestation onwards, earlier than previously believed. WHAT IS KNOWN ALREADY: During placental establishment and remodeling of maternal spiral arteries, endovascular trophoblast cells invade and accumulate in the lumen of these vessels to form 'trophoblast plugs'...

Levetiracetam (LVT) is a relatively novel antiepileptic drug (AED) known to act through binding with the synaptic vesicular 2A (SV2A) protein, thus modulating the presynaptic neurotransmitter release. The tryptophan metabolite quinolinic acid (QUIN) acts as an excitotoxin when its brain concentrations reach toxic levels under pathological conditions. Since increased neuronal excitability induced by QUIN recruits degenerative events in the brain, and novel AED is also expected to exert neuroprotective effects in their pharmacological profiles, in this work the effect of LVT (54 mg/kg, i...

Propranolol is a highly lipid-soluble beta-receptor antagonist. We describe a case of mixed overdose, including propranolol, amlodipine and olanzapine, resulting in severe resistant hypotension which was successfully treated. A 21-year-old student ingested 6.4 g of propranolol, 280 mg of amlodipine and 560 mg of olanzapine. The patient was brought to the emergency department and exhibited signs of severe systemic toxicity - profound hypotension and circulatory collapse, respiratory depression and coma...

Proliferative vitreoretinopathy (PVR) is a blinding eye disease and there is no effective pharmacological measure to prevent PVR development. The difficulty comes from lack of potent antiproliferative agent and lack of sustained delivery to cover high-risk time window for PVR to develop. Lipid prodrug of PMEG, hexadecyloxypropyl 9-[(2-phosphonomethoxy)ethyl]guanine (HDP-PMEG), was prepared and was evaluated as a pharmacological adjuvant to surgical management of PVR. A dose-escalation study determined that the highest nontoxic dose for intravitreal use in pigmented rabbits was 3 µg per eye...

BACKGROUND: Metabolic syndrome is a combination of symptoms including obesity, dyslipidaemia, glucose intolerance and hypertension. Oxidative stress appears to be a pathophysiological factor that links these signs and encourages progression towards heart failure and diabetes. Nox4 is a hydrogen peroxide nicotinamide adenine dinucleotide phosphate (NADPH) oxidase isoform - found in various cardiovascular cells and tissues, but also in tissues such as the liver - which is involved in glucose and lipid homeostasis...

Whether non-alcoholic fatty liver disease (NAFLD) precedes insulin resistance (IR) or IR preludes/causes NAFLD has been long debated. Recent studies have shown that there are two phenotypes of NAFLD, 'genetic' vs 'metabolic' NAFLD. The former patients are more at risk of hepatocellular carcinoma and chronic liver disease the latter are more IR and at increased risk of type 2 diabetes (T2D). Even if they are not yet diabetics, from a metabolic point of view having NAFLD is equivalent to T2D with reduced peripheral glucose disposal and impaired suppression of hepatic glucose production, but without fasting hyperglycaemia...

The role of central leptin in regulating the heart from lipid accumulation in lean leptin-sensitive animals has not been fully elucidated. Herein we investigated the effects of central leptin infusion on the expression of genes involved in cardiac metabolism and its role in the control of myocardial triacylglyceride (TAG) accumulation in adult Wistar rats. Intracerebroventricular (icv) leptin infusion (0.2µg/day) for 7 days markedly decreased TAG levels in cardiac tissue. Remarkably, the cardiac anti-steatotic effects of central leptin were associated with the selective up-regulation of gene and protein expression of peroxisome proliferator-activated receptor β/δ (PPARβ/δ) and their target genes, adipose triglyceride lipase (ATGL), hormone sensitive lipase (HSL), pyruvate dehydrogenase kinase 4 (PDK4), and acyl CoA oxidase 1 (Acox1), involved in myocardial intracellular lipolysis and mitochondrial/peroxisomal fatty acid utilization...

BACKGROUND: Neuroinflammation is a recognized hallmark of Alzheimer's disease, along with accumulation of amyloid-β plaques, neurofibrillary tangles and synaptic loss. n-3 polyunsaturated fatty acids (PUFA) and molecules derived from them, including eicosapentaenoic acid-derived eicosanoids and docosahexaenoic acid-derived docosanoids, are known to have both anti-inflammatory and pro-resolving properties, while human observational data links consumption of these fatty acids to a decreased risk of Alzheimer's disease...

OBJECTIVE: Fructose consumption has been implicated in the development of obesity and insulin resistance. Emerging evidence shows that fibroblast growth factor 21 (FGF21) has beneficial effects on glucose, lipid, and energy metabolism and may also mediate an adaptive response to fructose ingestion. Fructose acutely stimulates circulating FGF21 consistent with a hormonal response. We aimed to evaluate whether fructose-induced FGF21 secretion is linked to metabolic outcomes in obese humans before and after bariatric surgery-induced weight loss...

Liver failure remains the leading cause of postoperative mortality after hepatectomy. The present study investigated the effect of treatment with allogenic mesenchymal stem cells (MSCs) on survival and liver regeneration 48h and 7 days after 80% hepatectomy in C57Bl/6 mice. To optimize their biodistribution, MSCs were grown on acellular human amniotic membranes (HAM) and applied as a patch on the remnant liver. This approach was compared with MSC infusion and HAM patch alone. Hepatectomized mice without any treatment were used as control group...

Previous investigations have shown that inflammation induces changes in lipid and lipoprotein metabolism, and increased expression of angiopoietin-like protein 3 (ANGPTL3) contributes to the development of dyslipidemia. Here we investigated whether there is a correlation between increased ANGPTL3 expression and dyslipidemia in mastitis mice. Thirty mice were divided into two groups: control group and Staphylococcus aureus (S. aureus)-induced mastitis mice group. Changes in the levels of blood lipids [total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C)]; activity of myeloperoxidase (MPO); concentrations of plasma inflammation biomarkers [interferon-γ (IFNγ), tumor necrosis factor α (TNFα), and interleukin-1α (IL-1α)]; concentration of plasma ANGPTL3 protein; lipoprotein lipase (LPL) activities in postheparin plasma; expressions of hepatic N-acetylgalactosaminyltransferase 2 (GALNT2), hepatic ANGPTL3 and adipose LPL were determined...

Lipid core nanoparticles (LDE) resembling LDL behave similarly to native LDL when injected in animals or subjects. In contact with plasma, LDE acquires apolipoproteins (apo) E, A-I and C and bind to LDL receptors. LDE can be used to explore LDL metabolism or as a vehicle of drugs directed against tumoral or atherosclerotic sites. The aim was to investigate in knockout (KO) and transgenic mice the plasma clearance and tissue uptake of LDE labeled with (3)H-cholesteryl ether. LDE clearance was lower in LDLR KO and apoE KO mice than in wild type (WT) mice (p < 0...

RATIONALE: Resolvins are bioactive lipid mediators that are generated from docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). We recently demonstrated that the DHA-derived resolvins D1 and D2 exert antidepressant effects. However, whether the EPA-derived resolvins E1 (RvE1) and E2 (RvE2) produce antidepressant effects is not clear. OBJECTIVES: We examined the antidepressant effects of RvE1/RvE2 in a murine lipopolysaccharide (LPS)-induced depression model using the tail suspension and forced swim tests...

OBJECTIVE: Most youth with type 1 diabetes do not meet the American Diabetes Association (ADA) and International Society for Pediatric and Adolescent Diabetes (ISPAD) targets for hemoglobin A1c (HbA1c), blood pressure (BP), lipids, and body mass index (BMI). We hypothesized that ISPAD/ADA goal achievement would be associated with better insulin sensitivity (IS) and cardiopulmonary fitness. METHODS: IS was quantified as glucose infusion rate (GIR) from a hyperinsulinemic-euglycemic clamp in youth with type 1 diabetes from the RESistance to InSulin in Type 1 ANd Type 2 diabetes (RESISTANT) (n = 86) and Effects of MEtformin on CardiovasculaR Function in AdoLescents with Type 1 Diabetes (EMERALD) (n = 41) cohorts (n = 127; age 15...

Increased circulating levels of apolipoprotein A-I (apoA-I), the major protein of high-density lipoprotein (HDL), by genetic manipulation or infusion, protects against melanoma growth and metastasis. Herein, we explored potential roles in melanoma tumorigenesis for host scavenger receptor class B, type 1 (SR-B1), and ATP-binding cassette transporters A1 (ABCA1) and G1 (ABCG1), all mediators of apoA-I and HDL sterol and lipid transport function. In a syngeneic murine melanoma tumor model, B16F10, mice with global deletion of SR-B1 expression exhibited increased plasma HDL cholesterol (HDLc) levels and decreased tumor volume, indicating host SR-B1 does not directly contribute to HDL-associated anti-tumor activity...

Lipid lowering properties of glucagon have been reported. Blocking glucagon signaling leads to rise in plasma LDL levels. Here, we demonstrate the lipid lowering effects of acute dosing with Glp1r/Gcgr dual agonist (DualAG). All the experiments were performed in 25 week-old male diet-induced (60% kCal fat) obese mice. After 2 hrs of fasting, mice were injected subcutaneously with vehicle, liraglutide (25nmol/kg) and DualAG (25nmol/kg). De novo cholesterol and palmitate synthesis was measured by deuterium incorporation method using D2O...

HIV patients develop hepatic steatosis. We investigated hepatic steatosis in transgenic mice expressing the HIV-1 accessory protein Vpr (Vpr-Tg) in liver and adipose tissues, and WT mice infused with synthetic Vpr. Vpr-Tg mice developed increased liver triglyceride content and elevated ALT, bilirubin and alkaline phosphatase due to three hepatic defects: 1.6-fold accelerated de novo lipogenesis (DNL), 45% slower fatty acid ß-oxidation, and 40% decreased VLDL-triglyceride export. Accelerated hepatic DNL was due to coactivation by Vpr of liver X receptor-α (LXRα) with increased expression of its lipogenic targets Srebp1c, Chrebp, Lpk, Dgat, Fasn and Scd1, and intranuclear SREBP1c and ChREBP...
