Lacourse, Karen A., Lisa J. Swanberg, Patrick J. Gillespie, Jens F. Rehfeld, Thomas L. Saunders, and Linda C. Samuelson. Pancreatic function in CCK-deficient mice: adaptation to dietary protein does not require CCK. Am. J. Physiol. 276 (Gastrointest. Liver Physiol. 39): G1302– G1309, 1999.—A CCK-deficient mouse mutant generated by gene targeting in embryonic stem cells was analyzed to determine...

the objective of this study was to determine the effect of different levels of chicory root and stem powder (crsp) and butyric acid (ba) combination on the performance, carcass traits, relative weight of internal organs and some blood parameters in broiler chickens. two hundred and forty one-day-old broilers (ross 308) were used in a completely randomized design with four treatments with six re...

the effects of zinc oxide (zno) and e. coli-derived 6-phytase supplemented-diet on the reproductive performance in aged broiler breeder hens and on immune responses of their progeny chicks were studied. in a 2×4 factorial arrangement, 2 inclusion levels (0 or 300 u kg-1 diet) of e. coli-derived phytase and 4 inclusion levels (30, 60, 90, and 120 mg kg-1 diet) of zno were provided from 62 throug...

Pseudocholinesterase (PChE), also known as plasma cholinesterase, is a serine hydrolase capable of hydrolyzing esters including acetylcholine, succinylcholine, mivacurium and ester type local anesthetics such as procaine, chloroprocaine, tetracaine, cocaine and heroin. PChE is synthesized by the liver, and is found in the plasma, the pancreas, the heart and the brain. It has a serum half life o...

This study investigated the chronic effect of enterostatin on body weight and some of the associated changes in postprandial metabolism. Rats were adapted to 6 h of food access/day and a choice of low-fat and high-fat (HF) food and then given enterostatin or vehicle by an intraperitoneally implanted minipump delivering 160 nmol enterostatin/h continuously over a 5-day infusion period. Enterosta...

PURPOSE The goal of this study was to determine the effect of contrast media on the signal behavior of single-shot echo planar imaging (ssEPI) used for abdominal diffusion imaging. MATERIALS AND METHODS The signal of an ssEPI spin echo sequence in a water phantom with varying concentrations of gadolinium was modeled with Bloch equations and the predicted behavior validated on a phantom at 1.5...

background: diabetes is a major public health problem. the development of new therapies that are able to improve glycemia management and even to cure diabetes is of great interest. in this study, protective effects of sodium tungstate against stz-induced beta-cell damages were investigated. methods: sixty rats were divided into six groups: control, diabetic, sodium tungstate treated diabetic ra...

Background: For preclinical evaluations of radiopharmaceuticals, most studies are carried out on mice. Values of electron specific absorbed fractions (SAF) have had vital role in the assessment of absorbed dose. In past studies, electron specific absorbed fractions were given for limited source target pairs using older reports of human organ compositions.Objective: Electron specific absorbed fr...

A 53−year−old woman presented with a history of abdominal pain, nausea, vomit− ing, and a 40−kg weight loss, without change in bowel pattern. Physical exami− nation revealed epigastric tenderness, good bowel sounds, and an abdominal fluid wave. Rectal examination was nor− mal without occult blood. Abdominal computed tomography (CT) scan revealed a hypodense area of enlargement in the head of th...
