Abstract:
The Duodenary Cycle is a method of reckoning time that is used widely in mainland Southeast Asia. In the upland areas, ethnic groups that have historically been in contact with speakers of Chinese and Tai languages commonly use a 12-day cycle for determining what livelihood and ritual activities should be done on which days. The terminology used in these cycles shows influence from different cultures and languages, but there has also been asignificant degree of internally motivated innovation. In this paper we explore data from several Tibeto-Burman languages spok

Abstract:
Daily secretion of pancreatic juice, including postprandial responses to food, was investigated in two groups of calves: preruminant (fed with liquid food) and ruminant (fed with solid food). Male Friesian calves (1 week old and 6 weeks old) were surgically fitted with a pancreatic duct catheter, duodenal cannula and two duodenal electrodes. Continuous 24 h collections of pancreatic juice and myoelectrical recordings were performed with minimal restraint and disturbance of animals. In both groups of calves clear periodic fluctuations in pancreatic juice secretion (volume, protein output and tr

Abstract:
The migrating motor complex (MMC) shows large variations within an individual and between individuals. This study aimed to investigate, with respect to this variability, the importance of gastric or duodenal origin of phase III activity. Interdigestive 6- to 10-h stationary antroduodenal motility recordings of 19 healthy male subjects were analyzed for MMC cycle durations and duration of phases I, II, and III, all with respect to the place of origin of each phase III. Data are given for the duodenal recording site as means ± SE. Mean MMC cycle duration was 117.3 ± 13.9 min, regardless of the p

Abstract:
The role of nerves, gastrointestinal peptides, and gastroduodenal contents in the regulation of pancreatic periodic function were studied in preruminant calves. Nine male, Friesian calves were surgically fitted with pancreatic and duodenal catheters, abomasal and duodenal cannulae, and duodenal electrodes. Pancreatic secretion oscillated in phase with the duodenal migrating myoelectric complex. Pancreatic secretion and duodenal motility were abolished by intravenous atropine (5 μg∙kg−1∙min−1). The frequency of pancreatic and duodenal cycles was similarly increased by motilin and decreased by p

Abstract:
In 22 healthy volunteers distal duodenal fluid absorption was related to the interdigestive motility cycle. Fluid absorption was measured with a triple-lumen perfusion technique, and motility was registered with a low-compliance pneumohydraulic system. Pancreatic and biliary secretions were estimated by measurement of bilirubin and amylase release into the duodenal segment. Duodenal fluid absorption rate changed during the interdigestive motility cycle; the highest absorption rate was registered during phase I (low-motor activity) and absorption rate then decreased in parallel with increasing

A relationship between duodenal myoelectric or motor activity and exocrine pancreatic secretion as well as plasma gut hormone levels has been investigated in fasted dogs, fed dogs, and dogs that were stimulated with exogenous gut hormones. Pancreatic secretion showed typical periodicity in phase with the myoelectric or motor activity of the duodenum.

We determined if changes in the irregular motor activity of phase II, the dominant motility phase in awake fasting humans, are associated with fluctuations in pancreatic secretion by intubating the upper gastrointestinal tract of 15 healthy humans and recording antral and duodenal motility and obtaining duodenal samples for one or two interdigestive motility cycles. Antral phase II activity was graded as having low, intermediate, or high frequency of contractions and related to duodenal trypsin output and plasma concentrations of motilin and human pancreatic polypeptide (HPP), a marker of vaga

AbstractThe stomach and small intestine manifest a myoelectric activity pattern called the migrating myoelectric complex (MMC), which is controlled by both environmental and intrinsic factors. The daily MMC pattern has been little investigated, therefore the purpose of the present study was to study it, in weaned pigs given food twice a day. A wireless telemetric recording system was used for 24-h electromyography of the antrum and duodenum. The activity of the antrum showed little change if any, whereas the myoelectric activity of the duodenum significantly changed with respect to the time of

Heme-mediated oxidation in red meat is described as one of the potential routes to meat-induced colorectal cancer, which is linked to the ability of this reaction to continue also during gastrointestinal (GI) digestion while generating reactive aldehydes such as e.g. malondialdehyde (MDA), 4-hydroxy-2-nonenal (HNE) and 4-hydroxy-trans-2-hexenal (HHE). Very little is however known about the specific forms of heme being present at different stages of the GI-tract, and how mammal heme-proteins compare to those of for example fish with respect to their lipid pro-oxidative activity under GI-conditi
