Comparison Of Antibiotic Resistance Patterns Of Uropathogenic Escherichia Coli In Outpatient And Inpatient Populations From 1990 To 1996 In Bemidji, Mn, Gail R. Conway, Patrick Guilfoile
Comparison Of Antibiotic Resistance Patterns Of Uropathogenic Escherichia Coli In Outpatient And Inpatient Populations From 1990 To 1996 In Bemidji, Mn, Gail R. Conway, Patrick Guilfoile
Journal of the Minnesota Academy of Science
A retrospective study of antibiotic susceptibility was conducted on data from all uropathogenic Escherichia coli submitted to the MeritCare Clinic-Bemidji, MN and the North Country Regional Hospital-Bemidji, MN during 1990, 1993, and 1996. The proportion of antibiotic resistant strains was generally equal or higher in E. coli isolates from community-acquired infections than with E. coli isolates from nosocomial infections. Comparison with antibiotic prescriptions during 1990, 1993, and 1996 provided no clear relation between antibiotics prescribed for outpatient urinary tract infections and the proportion of E. coli strains resistant to those antibiotics. This suggests that factors other than selection for resistance …
Interplanetary Magnetic Field Sector Polarity And Neuropsychiatric Adaption: A Reanalysis, Hans W. Wendt
Interplanetary Magnetic Field Sector Polarity And Neuropsychiatric Adaption: A Reanalysis, Hans W. Wendt
Journal of the Minnesota Academy of Science
Recent Russian studies reported associations between adaptation syndromes and (solar activity-related) interplanetary magnetic field (IMF) sector polarity. Certain ambiguities in the original work suggested some reanalyses, based on the graphs and data made available. Syndrome status exhibited a biphasic (semi annual) trend. It also correlated with specific geomagnetic changes during magnetic storms and possibly after sudden impulses. Moreover, lag effects and higher order interactions were noted among all parameters investigated. The restudy tends to support some of the original findings but also suggests new conclusions regarding potential relationships between geophysical/solar and psychophysiological processes.
Chemicals And Food: An Account About Additives, Wayland E. Noland
Chemicals And Food: An Account About Additives, Wayland E. Noland
Journal of the Minnesota Academy of Science
Food additives are listed by functional category and discussed in terms of the scale of their use and relative risks in terms of long-term human toxicity. The greatest risks appear to lie with the antimicrobial preservative agents, and food colors (which serve only a cosmetic purpose); these and the synthetic sweeteners are discussed in relatively greater detail.
Chlorofluorocarbon Effects On Cardiac, Pulmonary, And Respiratory Patients, Mildred E. Olson
Chlorofluorocarbon Effects On Cardiac, Pulmonary, And Respiratory Patients, Mildred E. Olson
Journal of the Minnesota Academy of Science
Research results from studies of the physiological effects of aerosal propellants on animals and people are summarized. The papers selected for this summary were published between 1968 and 1975. Effects of the 15 chlorofluorocarbons used as propellants have been recorded on the cardiac, pulmonary and respiratory functions of a number of animal species as well as man. The fifteen propellants have been classified into four groups on the basis of their degree of toxicity. Fluorocarbon 11, the most frequently used propellant, is in group 1, the most toxic. The relative toxicity of each of the 14 other propellants compared with …
Measurement Of Permeability Of The Cell Membrane To Water, Richard Moore, Frederick Thornburgh, Donggyu Jin
Measurement Of Permeability Of The Cell Membrane To Water, Richard Moore, Frederick Thornburgh, Donggyu Jin
Journal of the Minnesota Academy of Science
The water permeability was measured for blood cells from normal subjects and for blood cells from patients with leukemia. The method of measurement of the kinetics of water influx employed a stopped flow apparatus. The method of calculation of results was based on irreversible thermodynamics. The measurements and calculations were both performed with the assistance of a computer. The water permeability of the leukemic cells was decreased from normal, and the values were more variable than normal. Leukemia changes the structure of the cell membrane.
Scientific Approach To 4-H Food Projects, Grace Brill
Scientific Approach To 4-H Food Projects, Grace Brill
Journal of the Minnesota Academy of Science
The scientific approach to 4-H food projects resulted from the stress on science from federal extension personnel of the U.S. Department of Agriculture, and from surveys and consultations with representatives of the National Science Foundation. The result has been six bulletins prepared by the extension nutritionists of the University of Minnesota for the approximately 24,000 4-H members, aged 9 to 19, enrolled in 4-H food projects in Minnesota. The scientific approach has, consequently, added the question of "why" to the traditional 4-H approach of "how-to-do-it."
