A Model of Extracellular Enzymes in Free-Living Microbes: Which Strategy Pays Off?

A model of extracellular enzymes in free-living microbes: which strategy pays off?

An initial modeling approach was applied to analyze how a single, nonmotile, free-living, heterotrophic bacterial cell may optimize the deployment of its extracellular enzymes. Free-living cells live in a dilute and complex substrate field, and to gain enough substrate, their extracellular enzymes must be utilized efficiently. The model revealed that surface-attached and free enzymes generate u...

Early intervention in rheumatoid arthritis pays off

The outlook for patients with newly diagnosed rheumatoid arthritis (RA) has improved greatly, but many questions remain, including when to initiate therapy and what drugs to use. Recently issued recommendations for managing early RA include referring patients who present with arthritis of more than 1 joint to a rheumatologist. Combination's of drugs have been shown to be more effective than mon...

the effectiveness of strategy-based instruction in teaching english as a second or foreign language: a meta-analysis of experimental studies

a large number of single research studies on the effects of strategy-based instruction (sbi) in teaching english as a foreign or second language has been conducted so far. however, the lack of a comprehensive meta-analysis targeting the effectiveness of english language sbi is observed. moreover, the findings of experimental studies regarding the context of the english language, proficiency lev...
