Muscle cells from human gallbladders (GB) with cholesterol stones (ChS) exhibit a defective contraction, excess cholesterol (Ch) in the plasma membrane, and lower binding of CCK-1 receptors. These abnormalities improved after muscle cells were incubated with Ch-free liposomes that remove the excess Ch from the plasma membrane. The present studies were designed to investigate the role of caveoli...

In this study, cow reticulorumen content pH and temperature together with the activity were registered using smaXtec boluses, specially designed for animal care. Body weight, rumination time, milk fat/protein ratio, yield, lactose, electrical conductivity, somatic cell count consumption of concentrated feed by Lely Astronaut® A3 milking robots. The cows in study assigned into two groups accordi...

Acute gastric remnant dilation is a rare postoperative complication of laparoscopic Roux-en-Y gastric bypass (LRYGB) occurring in 0–0.8% of cases [1–7]. It is usually associated with jejunojejunostomy obstruction or gastric remnant ulcer formation. The typical presenting symptoms include left upper quadrant abdominal pain, hiccups, and persistent tachycardia. It is managed by gastrostomy tube d...

AIM To study the direct correlation between gastric dysrhythmias and in vivo gastric muscle tone. METHODS Five healthy dogs were implanted with 4 pairs of electrodes along the greater curvature, with a strain gauge (SG) being sutured parallel to the distal electrodes (2 cm above the pylorus). Intravenous vasopressin was given to induce gastric dysrhythmia. The percentage of regular slow waves...

Cholesterol gallstones are one of the most prevalent and most costly digestive diseases in the developed countries. Although precipitation of cholesterol from supersaturated bile is the first irreversible physical-chemical step in cholesterol gallstone formation, hepatic hypersecretion of biliary cholesterol is the primary defect in the formation of cholesterol gallstones. The other common abno...

Gastrointestinal motility and plasma PYY levels were investigated under chronic progressive large bowel obstruction in dogs. The obstruction device was applied around the descending colon at a laparotomy and gastrointestinal motility was recorded with strain gauge force transducers in the conscious state. Complete obstruction occurred at 26 days (21-33 days). The duration of postprandial interr...
