In Pierrehumbert (1980) three rising accents are posited for English, H*, L+H* and L*+H, but this three-way contrast has often been disputed. In the present experiment, Minnesotan and Southern Californian speakers read two dialogs which included four levels of emphasis. Emphasis lengthened segmental duration, raised the scaling of all tones and delayed H alignment in L+H*. Independently of emph...

BACKGROUND Matricaria chamomilla commonly known as "Chamomile" (Asteraceae) is a popular medicinal herb widely used in indigenous system of medicine for a variety of ailments. However, there is no detailed study available showing its effectiveness in hyperactive gut disorders like, abdominal colic and diarrhoea. This study was designed to determine the pharmacological basis for the folkloric us...

1. Thirty-five pigs were fitted with single re-entrant cannulas in either the duodenum, jejunum or ileum. A further twenty-four pigs were used in a conventional digestibility trial. 2. Methods for collecting, sampling and returning digesta were developed. 3. A 'practical-type' diet and two purfied diets were used, fed twice daily. 4. Flow and pH of digesta were measured hourly in the duodenum a...

1. Proteolytic (substrate nitrocasein), tripeptidase (substrate glycylglycylgly-cine) and aminopeptidase (substrate leucyl-beta-naphthylamide) activities were studied in homogenates of jejunal and ileal mucosa of 7-, 10-, 14-, 21-, 35- and 60-day-old rats. 2. Proteolytic activity was practically the same in jejunum of 7-, 10-, 14- and 21-day-old rats, but after day 21 a significant increase was...

Stimulation of Ca2+ absorption can counteract hypocalcemia at the onset lactation. The plant bioactive lipid compound (PBLC) menthol is an agonist for nonselective cation channels transient receptor potential (TRP) family. It acutely stimulated in ruminal epithelia nonadapted animals ex vivo and caused higher plasma concentrations cows sheep vivo. To elucidate pathway by which feeding increases...

the purpose of this study was to look for carbon materials for composting with rabbit manure. rabbit manure was composted with rice straw and mushroom residues. during the composting process, different related parameters were evaluated. results showed that the rabbit manure could be normally co-composted with rice straw or with mushroom residues. the gi value showed that both composts could hel...

Gastrointestinal stromal tumors (GISTs) of the duodenum are relatively rare and difficult to diagnose in early stage because it lacks pathognomonic symptoms. Here, we report a case of multiple GISTs involving the third and fourth portions of the duodenum and proximal jejunum, which were revealed in an emergent laparotomy. A 40-year-old, previously healthy man was referred to the Emergency Depar...

Jejunum and ileum from vitamin D-deficient rats actively secreted calcium when studied in vitro, while duodenum from these animals actively absorbed calcium. Acute repletion with a single physiologic dose of 25-hydroxyvitamin D3 (25-OH D3) (15 i.u.) increased calcium absorption in duodenum and ileum but had no effect on jejunum. Studies of the distribution of 25-OH D3 and its metabolites in the...

Abstract Forty Holstein bull calves were fed 1 of 3 starch-based milk replacers for either 10 or 35 days to determine responses in organ mass and small intestinal length. Calves (87.2 ± 7.7 kg) bottle-fed a cornstarch-based replacer (727 g cornstarch daily) alone, with added casein (154.7 g/d) glutamate (45.5 d. Prior receiving treatments commercial 12 15 weeks so that measures length collected...

Corticotropin-releasing factor (CRF), a hypothalamic releasing hormone, is now known to be widely distributed in extrahypothalamic tissues such as the pancreas and gastrointestinal tract. There are, however, no data concerning the development of CRF in the gastrointestinal tract in immature animals. Using a specific RIA technique for rat CRF, we have determined the IR-CRF concentrations in acid...
