The effects of rumen digesta volume and pH on VFA absorption and its relation to rumen wall morphology were evaluated. Nine rumen cannulated cows formed 3 groups based on desired variation in rumen morphology: The High group was formed by Holsteins yielding 25.9 kg milk/d and fed on a high-grain
On the day before birth, mouse fetuses were tested for their behavioral responses to iso-amyl acetate and iso-valeric acid delivered into the nasal cavity in liquid phase. Pilot studies established that most subjects responded to most concentrations used with an increase in total behaviors and
Porous molecular nanocontainers of {Mo132 }-type Keplerates offer unique opportunities to study a wide variety of relevant phenomena. An impressive example is provided by the highly reactive {Mo132 -CO3 } capsule, the reaction of which with valeric acid results in the very easy release of carbon
A qualitative and quantitative study has been carried out on 15 strains of the Veillonella genus, isolated in the oral cavity. Following two methods of preparation of samples for injection in a chromatograph GL, we have identified among the volatil monocarboxylic aliphatic acids from C2 to C6 the
The lipid compositions of two spirochetes isolated from the human oral cavity and two isolated from pig feces were examined. These isolates were unusual in that they did not require long-chain fatty acids for growth, as do the other host-associated spirochetes, but rather required isobutyric and
