As espécies recentes reportadas para o gênero Meioceras Carpenter, 1858 (Mollusca: Caenogastropoda: Caecidae) no Atlântico oeste
… or subgeneric of the taxon in relation to Caecum Fleming, 1817. ln this study the taxon Meioceras is recognized as a valid genus apart from Caecum, based on conchililogical diagnostic characters: the helicoidal young shell and the swollen appearance in the first third part or in the middle …

Effects of dietary components on antibiotic resistance using mechanistic and plasmid based studies
… to extract plasmids from the complex broiler caecum was investigated, and determined to be the exogenous plasmid isolation method. Analysis into the plasmids present in the broiler caecum was performed for a greater understanding of the genetic basis of this resistance. Plasmids were …

Pathogenesis of post surgical adhesions and prevention using a novel fibrin sealant
… separate studies; 83% for the pig stomach/colon/caecum abrasion model, from 2 separate studies; 80% for the rat caecum abrasion model. This is significantly better than other fibrin sealants investigated in this thesis. PSA prevention with novel fibrin sealant demonstrated a similar pattern to …

Indagine sulla presenza di Helicobacter pullorum in allevamenti avicoli italiani
… chickens, laying hens and turkey, a total of 365 caecum contents of animals reared in 76 different farms were collected at the slaughterhouse. A caecum content of a ostrich was also sampled. In addition, with the aim of investigating the occurrence of H. pullorum in humans, 151 faeces were …

An investigation of the distribution of gastrin-like activity, and its nature, in the gastrointestinal tract of the sheep
… omasum, abomasal body, antrum, duodenum and caecum. The antrum showed the highest concentration of gastrin-like activity, but substantial concentrations were found in the rumen, reticulum, omasum and caecum and proximal duodenum declining progressively with distance from the pylorus. A lesser …

ß-Cyclodextrin-haltige Filmüberzüge zur Dickdarm-spezifischen Wirkstoff-Freisetzung
… letzten Teil des Dünndarms und dem Blinddarm (Caecum). Beim zeitkontrollierten Ansatz wird die einigermaßen konstante Dünndarmpassagezeit von 3 – 4 Stunden ausgenutzt. Der hohe peristaltische Druck des Dickdarms ist das Prinzip von druckkontrollierten Arzneiformen. Als verlässlichstes Konzept …

Biologia reprodutiva e estrutura de duas populações de Coscinasterias tenuispina (Lamarck, 1816) (Echinodermata: Asteroidea) na região do Cabo Frio, Rio de Janeiro
… relationship between gonad and pyloric caecum indices was not evident. The continuous spawning suggests that larva are producing throughout the year. Although this continuous spawning, low frequency of small individuals (≤ 3 mm) was recorded in a few months at Prainha and this …

The nutritonal ecology of meadow voles (Microtus pennsylvanicus) under differing environmental conditions
… and dry mass of the stomach, small intestine, caecum, large intestine, adrenal glands, liver, and kidneys was evaluated. Data was analyzed by ANOVA using the SAS system. Meadow voles increased food intake but decreased turnover time and digestive efficiency under low ambient temperature …

Effects of phytogenics on intestinal pathogenic bacteria and microbiota of non-ruminants
… in broth and in selective broth with chicken caecum content. The findings showed A. pilosa Ledeb, A. chinensis Bunge, S. glabra Roxb reduced caecum colonisation of E. coli, L. monocytogenes, and S. enteritidis in vitro within 0.5 hours. The results indicated a significant reduction of ≥99.9% …

A microbiological and molecular study of campylobacter and related species isolated from ostriches (Struthio camelus)
… microbiological assays were performed on liver, caecum and colon samples predominantly from healthy ostriches presented for slaughter, to detect any Epsilonproteobacteria present. Samples were collected at an abattoir in the Western Cape between February and December 2010. Qualitative …

Die Rolle der Umamirezeptoruntereinheit Tas1r1 jenseits ihrer gustatorischen Bedeutung
… erstmals spezifisch auf zellulärer Ebene. Caecum und Lymphknoten wurden zudem neu als Expressionsorte des Tas1r1 identifiziert. Trotz der beobachteten weiten Verbreitung des Tas1r1 im Organismus – unter anderem auch in Geweben, die für den Proteinstoffwechsel besonders relevant sind – waren …

Control of the release of digestive enzymes in the cricket Gryllus bimaculatus and the fall armyworm, Spodoptera frugiperda
… Using flat-sheet preparations of the caecum, digestive enzyme release was investigated. More trypsin, aminopeptidase and amylase are secreted in the caecum of fed crickets than in unfed crickets, but basal levels of certain enzymes are released continuously even in unfed animals. A …

The role of Dietary Interventions in Broiler Intestinal Health and Immunity
… supplementation in the duodenum, jejunum and caecum. Supplementation of mannan rich fraction 3 (MRF-3) significantly enhanced protein expression levels of p-Akt. MRF-2 and MRF-3 dietary incorporation led to a significant decrease in RIPK3 protein expression levels. Dietary additive inclusion …

Characterisation of Host- Parasite- Microbiota Interactions that Drive Hatching in Trichuris Species
… ingestion of whipworm eggs that hatch in the caecum and proximal colon, liberating larvae that establish in the intestinal epithelia. Trichuriasis has been studied in murine and porcine models of infection, with Trichuris muris and Trichuris suis respectively; revealing the role of the host …

Isolation and characterization of the B-type allatostatin gene of Gryllus bimaculatus de Geer (Ensifera, Gryllidae)
… reproductive glands of female crickets. In the caecum and midgut, Grybi-AS B gene expression was found in endocrine secretory and epithelial cells, whereas in the hindgut, positive RT in situ PCR signals were detected in both longitudinal and circular muscles and in the gut epithelial cells. …

Studies on the biology of Cyathocephalus truncatus (Pallas, 1781) (Cestoda : Spathebothridea) in its fish and crustacean hosts
… an attachment in the distal end of a pyloric caecum 3 days after infection and matures in 8-10 days with production of eggs. By the 15th day the attachment to host tissue has become so firm that it is impossible to separate the worm from it. The tapeworm's hold on the caecal wall is probably …

Characterising dysbiosis in Alzheimer’s disease utilising the APP/PS1 mouse model
… in the mucosal- associated microbiota in the caecum of APP/PS1 mice. The dysbiosis was accompanied by a significant decrease in crypt depth and an increase in EEC numbers in the colon. The results suggest that dysbiosis in the large intestine occurs in early neuropathology and is normalised by …

Alimentação, ciclo reprodutivo e associação de Loligo sanpaulensis Brakoniecki, 1984 (Cephalopoda: Loliginidae) com a ictiofauna demersal na plataforma costeira do Cabo Frio, RJ
… specimens. The degree of stomach and digestive caecum fulness were examinated on 859 specimens and 351 squids had their stomach contents analysed. Loligo sanpaulensis occurred over the shelf in all seasons, with a mean catch of 39.2 ind/hour trawling. Best yields were obtained at 45 m depth with …
