Chemical characterization and in vitro biological activity of four tropical legumes, Styzolobium aterrimum L., Styzolobium deeringianum, Leucaena leucocephala, and Mimosa caesalpiniaefolia, as compared with a tropical grass, Cynodon spp. for the use in ruminant diets
rumen fermentation gas production kinetics PEG
2015/6/23
Kinetic parameters were estimated
by an exponential model. STA, STD, and LEU contained higher (P < 0.05) crude protein than MIC, which
had greater neutral detergent fibre and acid detergent fibre....

Synthesis and biological activity of novel anti-juvenile hormone agents
juvenile hormone anti-juvenile hormone precocious metamorphosis uvenile hormone esterase
2009/3/5
Ethyl 4-[2-(tert-butylcarbonyloxy)butoxy]benzoate (ETB) is a partial juvenile hormone (JH) antagonist which targets larval epidermis. We converted ETB to ethyl 4-(2-substituted alkyloxy)benzoates. T...
Effect of pH on the Conformation and Biological Activity of Clostridium septicum Alpha-toxin, a Pore-forming Hemolysin
Clostridium septicum alpha-toxin hemolytic activity lethality pH
2009/1/19
The effects of pH on the pore-forming Clostridium septicum alpha-toxin that causes myonecrosis was assessed at pH 5.0, 7.0 and 9.0 by measuring circular dichroism and its biological activity. Incubat...
