A Study to Evaluate the Effect of Lipid Infusion on TLR4 Signaling

2015-03-27 05:53:22 | BioPortfolio


The purpose of this study is to determine whether a lipid infusion can up-regulate toll-like receptor 4 (TLR4) signaling in human subjects


The investigators plan to examine the effect of a lipid infusion on TLR4 expression and insulin sensitivity. A group of 30 subjects aged 18-60 years old, lean (BMI < 26 kg/m2) normal glucose tolerant subjects without a family history of type 2 diabetes will receive a lipid or saline infusion. The subjects will be randomly assigned to first receive either a 48 hour long lipid or saline infusion. Approximately 4-6 weeks later subjects will return to undergo another study (if, in the first study they received lipid, on the second study they will receive saline, and vice versa). A near-equal number of women and men will be included in each group.

Effects of Intralipid Versus Olive Oil Infusions on Endothelial Function, Immune Function, Inflammatory Markers

Recent evidence suggests that increased levels of a circulation fat (free fatty acids or FFAs) can cause high blood pressure and cardiac complications. Intralipid is the only type of fat ...

Intralipid Versus SMOFlipid in HPN Patients

This study will randomize all patients who are new to the Mayo Clinic HPN team to either standard lipid emulsion (Intralipid) or SMOFLipid.

Cardiac REperfusion With Intralipid® at Reperfusion

This study will evaluate the benefit of Intralipid® or placebo administered prior to reperfusion to limit ischemia reperfusion injury as measured by the geometric mean difference of the r...

FFA Hypertension and Inflammation in Lean and Obese Subjects

Our recent studies indicate that increased levels of a circulating fat (free fatty acids or FFAs) increases blood pressure, impairs endothelial (vascular) function, and increases inflamma...

n-3 Fatty Acid Infusion and Type 2 Diabetes

The purpose of this experimental study is to investigate whether an acute lipid infusion added marine n-3 fatty acids produces effects on insulin sensitivity in subjects with type 2 diabet...

Low dose Intralipid resuscitation improves survival compared to ClinOleic in propranolol overdose in rats.

Medication overdose is a prevalent issue and despite mixed reports of efficacy, the use of intravenous lipid emulsions, notably Intralipid®, for the management of toxicity from lipid-soluble drugs is...

Intralipid® may represent a new hope for patients with reproductive failures and simultaneously an over-immune endometrial activation.

Continuous failures to achieve a pregnancy despite effective embryo transfers is extremely distressing for couples. In consequence, many adjuvant therapies to IVF have been proposed to achieve an "ide...

A single bout of strenuous exercise overcomes lipid-induced anabolic resistance to protein ingestion in overweight, middle-aged men.

High-circulating lipid availability attenuates protein feeding-induced muscle protein synthesis (MPS). Whether the combined effects of exercise and protein ingestion can rescue this inhibition is unkn...

Initial Fluid Therapy in Pediatric Diabetic Ketoacidosis: A comparison of Hypertonic Saline Solution and Normal Saline Solution.

The optimal fluid therapy in children with DKA is a matter of debate, especially if we take into account its association with cerebral edema, the most important complication. Hypertonic Saline Solutio...

The aim was to understand diabetes-related barriers and successes that people with diabetes (PWD) have in the context of work outside the home.

Medical and Biotech [MESH] Definitions

A genus of HALOBACTERIACEAE distinguished from other genera in the family by the presence of specific derivatives of TGD-2 polar lipids. Haloarcula are found in neutral saline environments such as salt lakes, marine salterns, and saline soils.

A family of gram-negative, moderately halophilic bacteria in the order Oceanospirillales. Members of the family have been isolated from temperate and Antarctic saline lakes, solar salt facilities, saline soils, and marine environments.

Urination of a large volume of urine with an increase in urinary frequency, commonly seen in diabetes (DIABETES MELLITUS; DIABETES INSIPIDUS).

The time period before the development of symptomatic diabetes. For example, certain risk factors can be observed in subjects who subsequently develop INSULIN RESISTANCE as in type 2 diabetes (DIABETES MELLITUS, TYPE 2).

A subclass of DIABETES MELLITUS that is not INSULIN-responsive or dependent (NIDDM). It is characterized initially by INSULIN RESISTANCE and HYPERINSULINEMIA; and eventually by GLUCOSE INTOLERANCE; HYPERGLYCEMIA; and overt diabetes. Type II diabetes mellitus is no longer considered a disease exclusively found in adults. Patients seldom develop KETOSIS but often exhibit OBESITY.
