Proteolytic Enzymes In The Marine Bacterium Pseudoalteromonas Atlantica: Post-Secretional Activation And Effects Of Environmental Conditions, Monica Hoffman, Alan W. Decho
Proteolytic Enzymes In The Marine Bacterium Pseudoalteromonas Atlantica: Post-Secretional Activation And Effects Of Environmental Conditions, Monica Hoffman, Alan W. Decho
Faculty Publications
Production and activities of cellular and extracellular proteolytic enzymes associated with the marine bacterium Pseudoalteromonas atlantica were examined in response to physiological state and changing environmental variables under laboratory conditions. Enzymes evidenced by zymography were metalloproteases, as defined by substrate preference and susceptibility to inhibitors (EDTA and 1, 10-phenanthroline). Distinct bands (i.e. molecular-weight [MW] size classes) of enzymes were isolated from within cellular and extracellular compartments. Susceptibility of extracellular enzymes to environmental stressors was related, in part, to the MW size classes of the enzymes. While all bands of enzymes showed some degree of inhibition when pH was decreased, the …

Objective: Because the percentage of missing portion sizes was large in the Aerobics Center Longitudinal Study (ACLS), careful consideration of the accuracy of standard portion sizes was necessary. The purpose of the present study was to investigate the consequences of using standard portion size instead of reported portion sizes on subjects' nutrient intake.
Methods: In 2307 men and 411 women, nutrient intake calculated from a 3-day dietary record using reported portion sizes was compared with nutrient intake calculated from the same record in which standard portion sizes were substituted for reported portion sizes.
Results: The standard portion sizes provided significantly …

Background - Although medical textbooks usually classify fasting plasma glucose <70 or 80 mg/dL (<3.89 or 4.44 mmol/L) as abnormal, the prognosis for patients with low fasting plasma glucose is unclear.
Methods and Results - We conducted prospective cohort studies among 40,069 men and women to investigate the association between fasting plasma glucose levels and cardiovascular disease and all-cause mortality. We documented a U-shaped relation between fasting plasma glucose and mortality. In addition to diabetes and impaired fasting glucose levels, low fasting plasma glucose levels were also associated with high morality. After multivariate adjustment for age, sex, study population, ethnicity, current smoking status, high blood pressure, total cholesterol, body mass index, triglycerides, history of cardiovascular disease and cancer, and a family …

Low levels of physical activity and fitness substantially increase risk of several chronic diseases, reduce longevity, and lead to loss of function. The strength and relation of inactivity to health problems and the high prevalence of sedentary habits in most countries of the world make lack of exercise a major public health problem. Fortunately, there is now good consensus regarding public health recommendations for physical activity from many important medical, scientific, and public health organizations. Recent research on physical activity interventions provides additional approaches to helping sedentary adults become more physically active.

Dengue And Aedes Aegypti: A Public Health Problem Along The United States-Mexico Border (Lecture Number 1 - A Series Of Dengue Lectures), Frank Cortez Flores
Frank Cortez Flores
My primary public health interest is the reemerging arboviral infections (e.g., dengue) that are increasing in incidence, expanding into new geographic areas, affecting new populations, and are threatening to increase in the near future, especially following a natural disaster (e.g., hurricanes). The goal of the dengue lecture series is to promote the recognition of dengue and dengue hemorrhagic fever and improve the understanding of factors involved in prevention, surveillance and control of the Aedes aegypti mosquito, the principal mosquito vector of dengue virus. The purpose of these lectures is to accelerate learning and development of an effective dengue prevention and …
