Secretion of DNases by Marine Bacteria: A Culture Based and Bioinformatics Approach.

The vast majority of bacteria present in the natural environment are present in the form of aggregates and/or biofilms. Microbial aggregates are ubiquitous in the marine environment and are inhabited by diverse microbial communities which often express intense extracellular enzymatic activities. However, the secretion of an important group of enzymes, DNases, by bacteria from marine aggregates has not been studied, despite the importance of these aggregates in biogeochemical cycling of nutrients in the oceans.

Doctor-patient interaction, patients' health behavior and effects of treatment.

Studies of doctor-patient communication and its consequences are usually limited to factors that may determine patients' compliance with doctors' instructions. But many patients besides or instead of following doctors' advice undertake additional activity in order to get well. The purpose of this study was to explore the whole range of patients' health behavior, its connection with the process of doctor-patient interaction (as an independent variable) and with the treatment results (as a dependent variable).
