1. Intake and digestion of non-traditional feedstuffs by farmed collared peccary (Mammalia, Tayassuidae)
ABSTRACT To assess the ability of the collared peccary ( Pecari tajacu ) to digest dietary fiber, four adult male collared peccaries were randomly assigned to a 4 × 4 Latin square design to determine the effects of feeding non-traditional feed ingredients, taken from palm trees with different levels of dietary fiber, on intake and coefficient of total tract

2. The impacts of Elaeagnus umbellata Thunb. leaf and fruit aqueous extracts on mice hepatic, extrahepatic antioxidant and drug metabolizing enzymes related structures
ABSTRACT In this work, the potential chemopreventive activities of Elaeagnus umbellata fruit aqueous (EUFA) and leaf aqueous (EULA) extracts focusing on the modulatory influence of xenobiotic metabolizing enzymes (XMEs), antioxidant enzymes, glucose-6-phosphate dehydrogenase (G6PD), 6-phosphogluconate dehydrogenase (6PGD), lactate dehydrogenase (LDH) activit

3. Physiological adaptations of ruminants and their potential relevance for production systems
ABSTRACT Herbivores face the dilemma that the level of feed intake is negatively related to factors that determine digestive efficiency, such as thoroughness of ingesta comminution by chewing, and retention of digesta in the digestive tract. Ruminants have evolved particular adaptations to solve this dilemma. Most ruminants share the characteristic of “dig

4. AvaliaÃÃo morfofisiolÃgica da absorÃÃo e metabolizaÃÃo de Ãcidos graxos volÃteis pelo proventrÃculo de bovinos. / Morphophysiologic evaluation of the absorption and metabolism of volatile fatty acids by bovine forestomach.
About 60% of volatile fatty acids (VFA) produced in reticulorumen are absorbed in this compartment. The other 40% pass with the fluid phase to the omasum and are absorbed before entering the duodenum. Two experiments were carried out to determine the absorption surfaces and the VFA absorption and metabolism capacity of the bovine forestomach compartments. In

5. Digestion of Herring by Indigenous Bacteria in the Minke Whale Forestomach
Northeastern Atlantic minke whales (Balaenoptera acutorostrata) have a multichambered stomach system which includes a nonglandular forestomach resembling that of ruminants. Bacteria from the forestomachs of herring-eating whales were enumerated and isolated in an anaerobic rumen-like culture medium (M8W medium). The total viable population of anaerobic bacte

6. Baleen whales: preliminary evidence for forestomach microbial fermentation.
Baleen whales have a multichambered stomach divided into three distinct compartments. The forestomach (first compartment) consists of noncornified and nonglandular tissue and appears to be analogous to the tissue of the rumen. The exact function of the forestomach is unknown; however, we have detected volatile fatty acids in forestomach samples from seven bo

7. Biotin-labeled plasmid DNA probes for detection of epithelium-associated strains of lactobacilli.
Biotin-labeled DNA probes prepared from whole plasmids (5.5 and 4.8 kilobases) of two lactobacillus strains (Lactobacillus delbrueckii 21 and Lactobacillus reuteri 100-23) were used to detect the homologous bacteria in microtome-cryostat-prepared sections of murine forestomach. The forestomach sections were incubated on nylon filter membranes placed on agar

8. Forestomach motility in the chronically vagotomized sheep
1. The motility of the reticulo-rumen and omasum in conscious sheep was studied by electromyography from chronically implanted nichrome wire electrodes. The sheep were subjected to vagotomy and were maintained totally by intragastric infusion of liquid nutrients before and after vagotomy. Before vagotomy the motility of the forestomach was essentially simila

9. Keratin synthesis in normal mouse epithelia and in squamous cell carcinomas: evidence in tumors for masked mRNA species coding for high molecular weight keratin polypeptides.
Transplantable mouse squamous cell carcinomas (SCC), originally derived either from back skin or forestomach epithelium, do not synthesize high molecular weight keratin polypeptides [greater than 60 kilodaltons (kDa)] involved in the process of terminal differentiation in the corresponding normal tissues. The in vivo tumor keratin spectra consist of only low

10. Morphometry of mitochondria in ovine forestomach epithelia: high densities of mitochondria correlate with specialised metabolic activity.
The volume density of mitochondria and the surface density of mitochondrial inner membranes were investigated in the stratified squamous epithelia of the oesophagus and forestomachs of sheep, and in the oesophagus and nonglandular part of the ventricle of rats. The higher values found for both parameters in all forestomach regions are thought to be correlate

11. Bacteriophages from the forestomachs of Australian marsupials.
Bacteriophages were observed in forestomach contents from three species of Australian macropodoid marsupials possessing a foregut fermentative digestion: the eastern grey kangaroo (Macropus giganteus), the eastern wallaroo (Macropus robustus robustus), and the rufous bettong (Aepyprymnus rufescens). Forty-six morphologically distinct phage types, representin

12. Muir–Torre-like syndrome in Fhit-deficient mice
To investigate the role of the Fhit gene in carcinogen induction of neoplasia, we have inactivated one Fhit allele in mouse embryonic stem cells and produced (129/SvJ × C57BL/6J) F1 mice with a Fhit allele inactivated (+/−). Fhit +/+ and +/− mice were treated intragastrically with nitrosomethylbenzylamine and observed for 10 wk posttreatment. A total of
