Ghrelin is a gastric peptide hormone that controls appetite and energy homeostasis. Plasma ghrelin levels rise before a meal and fall quickly thereafter. Elucidation of the regulation of ghrelin secretion has been hampered by the difficulty of directly interrogating ghrelin cells diffusely scattered within the complex gastric mucosa. Therefore, we generated transgenic mice with ghrelin cell exp...

oxidation is the primary pathway for the production of energy for myocardial action. In the ischemic or infarcted myocardium with reperfusion, fatty acidβ-oxidation is easily suppressed and glucose metabolism plays the major role in supplying myocardial energy.1–3 Thus, 11Cpalmitate clearance may sensitively detect myocardial ischemia and damage from the viewpoint of fatty acidβoxidation. Howev...

Cultured largemouth bass (LMB) cannot be sold as food in some lucrative markets due to regulatory restrictions that protect wild LMB. Distinguishing between cultured and wild fish could open food markets for cultured fish. Wild LMB eat freshwater fish and cultured LMB eat diets high in marine fish meal and oil, which should produce differences in flesh composition. We analyzed the proximate and...

BACKGROUND The 13C-urea breath test (13C-UBT) is a simple, non-invasive and reliable test for the diagnosis of Helicobacter pylori infection. The duration of the test, the timing of breath sampling, and the accuracy of the method vary according to the test meal used. AIM To identify the optimal test meal or drink for rapid and accurate performance of the 13C-UBT for the detection of H pylori ...

BACKGROUND Low postprandial blood glucose is associated with low risk of metabolic diseases. A meal's ability to diminish the glucose response to carbohydrates eaten during the following meal is known as the "second-meal effect" (SME). The reduced glycemia elicited by low-glycemic-index (LGI) foods consumed during the first meal has been suggested as the main mechanism for SME. However, LGI foo...

In a previous study, several histological alterations were found in the liver of gilthead seabream Ž . fed with a diet containing 30% soybean meal SBM . In the current study, SBM containing diets Ž . were supplemented with either potassium phosphate, zinc sulfate or phytase Aspergillus ficuum , or increasing the dietary ny3rny6 fatty acids ratio to meet that of a fish meal based diet. Diet Ž . ...

Despite the reported association of lipoprotein responses to a fatty meal with atherosclerosis, little is known about the determinants of these responses. Plasma triglyceride, retinyl palmitate, and apolipoprotein B-48 responses to a standardized fatty meal containing a vitamin A marker were measured in 602 Atherosclerosis Risk in Communities (ARIC) study participants. To focus on postprandial ...

The myocardium is able to utilize both carbohydrates and noncarbohydrates for the performance of its work (1). Extraction of an individual substrate is usually determined by its arterial level. Thus, after a carbohydrate meal the heart derives much of its energy from the metabolism of carbohydrates; however, in the fasting state myocardial energy production is dependent upon noncarbohydrates, p...

Previous work has shown that a high-fat meal produces an increased coagulability of the blood. This fact is of interest in view of the effects of dietary fat on the serum cholesterol and its association with coronary disease. Since fats containing large amounts of unsaturated fatty acid tend to reduce the serum cholesterol rather than increase it, it is important to examine the effects of fats ...
