Numerous studies have shown that ingesting carbohydrate in the form of a drink can improve exercise performance by maintaining blood glucose levels and sparing endogenous glycogen stores. The effectiveness of carbohydrate gels or jellybeans in improving endurance performance has not been examined. On 4 separate days and 1-2 hr after a standardized meal, 16 male (8; 35.8 +/- 2.5 yr) and female (...

Progr. p. 7-11. Summary: Ten diverse accessions of perennial ryegrass (Lolium perenne L.) were grown in sand culture and exposed to a half-Hoagland solution amended with 0 (control), 50-, 100-, 150-, 200...

Pond-cypress, a deciduous conifer, is a dominant canopy species in depressional wetlands of the southeastern Coastal Plain (SCP). Extensive premature decline and death of pond-cypress trees in central Florida have been attributed to hydroperiod alterations due to excessive withdrawals of ground water from the Floridan aquifer. One factor identified in the decline process is basal decay, which m...

The effect of soluble fluorine species in different concentrations on the catabolic activity of Desulfotomaculum ruminis bacteria has been studied. The fluoride concentrations tolerated by and toxic to the bacteria have been determined. The degree of fluorine species toxicity was found to depend on the form in which fluorine is introduced into the medium and increases in the following order: Na...

It has been hypothesized that the increase in temperature in this century could lead to an increase in frost damage to plant tissues. Several models have been proposed to describe the development of cold hardiness, but never taking into account extreme climatic and/or physiological events. Our results on walnut tree (Juglans regia L.) show that cold hardiness was best correlated with average da...

The water soluble oxovanadium(IV) tetraarylporphyrin has demonstrated excellent solution stability against glutathione reduction and high potency (5 microM, 97% inhibition) in inhibiting HIV-1 replication in Hut/CCR5 cells.
