Gut transit and carbohydrate uptake
Classical assessments of nutritional adequacy rely on tables of supposed nutrient requirements for animals or for man on the one hand, and the ability of feedstuffs to provide them on the other. These are expressed in gross or overall digestibility terms and do not relate to differences in the rates of amounts of digestion occumng in different parts of the gut. Yet in the case of carbohydrates,...
متن کامل: examining l2 teachers’ corrective feedback types in relation to learners’ uptake, proficiency levels, and context types
abstract this study investigates the teachers’ correction of students’ spoken errors of linguistic forms in efl classes, aiming at (a) examining the relationship between the learners’ proficiency level and the provision of corrective feedback types, (b) exploring the extent to which teachers’ use of different corrective feedback types is related to the immediate types of context in which err...

متن کاملSynthesis of Bioinspired Carbohydrate Amphiphiles that Promote and Inhibit Biofilms.
The synthesis and characterization of a new class of bioinspired carbohydrate amphiphiles that modulate Pseudomonas aeruginosa biofilm formation are reported. The carbohydrate head is an enantiopure poly-amido-saccharide (PAS) prepared by a controlled anionic polymerization of β-lactam monomers derived from either glucose or galactose. The supramolecular assemblies formed by PAS amphiphiles are...
متن کاملMolecular characterization of ciliate diversity in stream biofilms.
Free-living protozoa are thought to be of fundamental importance in aquatic ecosystems, but there is limited understanding of their diversity and ecological role, particularly in surface-associated communities such as biofilms. Existing eukaryote-specific PCR primers were used to survey 18S rRNA gene sequence diversity in stream biofilms but poorly revealed protozoan diversity, demonstrating a ...
