Escherichia Coli O157:H7 And Other E. Coli Strains Share Physiological Properties Associated With Intestinal Colonization, Lisa Jacobsen, Lisa Durso, Tyrell Conway, Kenneth W. Nickerson

Kenneth Nickerson Papers

Escherichia coli isolates (72 commensal and 10 O157:H7 isolates) were compared with regard to physiological and growth parameters related to their ability to survive and persist in the gastrointestinal tract and found to be similar. We propose that nonhuman hosts in E. coli O157:H7 strains function similarly to other E. coli strains in regard to attributes relevant to gastrointestinal colonization.

Food Exemplar Salience: What Foods Do People Think Of When You Tell Them To Change Their Diet?, Carolyn R. Brown-Kramer, Marc T. Kiviniemi, Julie A. Winseman

Department of Psychology: Faculty Publications

Understanding which specific foods easily come to mind when individuals consider categories of dietary behavior may help explain observed patterns of dietary intake. We examined which specific behavioral exemplars are most easily retrieved from memory when individuals consider broad dietary categories. Participants reported specific foods that come to mind when considering high fat foods, low fat foods, and fruits/vegetables. Salient foods differed from those suggested in dietary guidelines, were distinct from those known to be major diet components, and showed a non-trivial number of incorrect responses. These findings have implications for understanding how individuals respond to dietary guidelines and devising …

Birth-Intervals And Sex Composition Of Western Gray Whales Summering Off Sakhalin Island, Russia, David W. Weller, Amanda L. Bradford, Aimée R. Lang, Robert L. Brownell Jr., Alexander M. Burdin

United States Department of Commerce: Staff Publications

Determining the birth-interval at which reproductive females produce calves is an indispensable component of studies on the population biology of large whales. In theory, shorter birth-intervals will result in a faster rate of population increase. Therefore, estimating this reproductive parameter is particularly important for modeling exercises designed to project the potential growth of a given population and, in the case of endangered populations, their ability to recover from a depleted state (e.g. Cooke et al., 2008). While a number of inherent biases exist with respect to determination of birth-intervals for baleen whales (Barlow and Clapham, 1997), dedicated sampling efforts and …

Chronic Wasting Disease Prions In Elk Antler Velvet, Rachel C. Angers, Tanya S. Seward, Dana Napier, Michael Green, Edward Hoover, Terry Spraker, Katherine O'Rourke, Aru Balachandran, Glenn C. Telling

Zoonotics and Wildlife Disease: Publications

Chronic wasting disease (CWD) is a contagious, fatal prion disease of deer and elk that continues to emerge in new locations. To explore the means by which prions are transmitted with high efficiency among cervids, we examined prion infectivity in the apical skin layer covering the growing antler (antler velvet) by using CWD-susceptible transgenic mice and protein misfolding cyclic amplification. Our finding of prions in antler velvet of CWD-affected elk suggests that this tissue may play a role in disease transmission among cervids. Humans who consume antler velvet as a nutritional supplement are at risk for exposure to prions. The …

Plant Growth-Promoting Rhizobacteria Allow Reduced Application Rates Of Chemical Fertilizers, A. O. Adesemoye, H. A. Torbert, J. W. Kloepper

Department of Plant Pathology: Faculty Publications

The search for microorganisms that improve soil fertility and enhance plant nutrition has continued to attract attention due to the increasing cost of fertilizers and some of their negative environmental impacts. The objectives of this greenhouse study with tomato were to determine (1) if reduced rates of inorganic fertilizer coupled with microbial inoculants will produce plant growth, yield, and nutrient uptake levels equivalent to those with full rates of the fertilizer and (2) the minimum level to which fertilizer could be reduced when inoculants were used. The microbial inoculants used in the study were a mixture of plant growth-promoting rhizobacteria …

The University Of Michigan Dioxin Exposure Study: Predictors Of Human Serum Dioxin Concentrations In Midland And Saginaw, Michigan, David H. Garabrant, Alfred Franzblau, James Lepkowski, Brenda W.

Department of Sociology: Faculty Publications

Background: We conducted a population-based human exposure study in response to concerns among the population of Midland and Saginaw counties, Michigan, that discharges by the Dow Chemical Company of dioxin-like compounds into the nearby river and air had led to an increase in residents’ body burdens of polychlorinated dibenzofurans (PCDDs), polychlorinated dibenzofurans (PCDFs), and dioxin-like polychlorinated biphenyls (PCBs), here collectively referred to as “dioxins.”

Objectives: We sought to identify factors that explained variation in serum dioxin concentrations among the residents of Midland and Saginaw counties. Exposures to dioxins in soil, river sediments, household dust, historic emissions, and contaminated fish and …

Background: The University of Michigan Dioxin Exposure Study (UMDES) was undertaken in response to concerns that the discharge of dioxin-like compounds from the Dow Chemical Company facilities in Midland, Michigan, resulted in contamination of soils in the Tittabawassee River floodplain and areas of the city of Midland, leading to an increase in residents’ body burdens of polychlorinated dibenzodioxins and polychlorinated dibenzofurans.

Objectives: The UMDES is a hypothesis-driven study designed to answer important questions about human exposure to dioxins in the environment of Midland, where the Dow Chemical Company has operated for > 100 years, and in neighboring Saginaw, Michigan. In addition, …

The Effect Of Retirement On Vigorous Physical Activity Controlling For The Socio-Demographic Variables Of Age, Gender, Education, Income, Race And Perceived Health Status Affect, Jayme D. Nekuda

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Health and Retirement Study data was used to examine the relationship between retirement and vigorous physical activity. The independent variables studied were vigorous physical activity in 1998 (T1) and retirement status in 2000 (T2). The dependent variable was vigorous physical activity in 2000 (T2). The entire sample consisted of 5,351 respondents who were in the workforce in 1998 (T1). In 2000 (T2), 4,449 reported still being in the workforce while 902 reported having retired between T1 and T2. The affect was controlled by the covariates of age, gender, education, income, race and perceived health status. These covariates together predicted approximately …

Sorghum Grain Mold: Sustainable Pest Management Strategies, Intsormil

INTSORMIL Impacts and Bulletins

Global losses due to grain mold are estimated to be $130 million annually. Sorghum grain mold is caused by a complex of fungal species, the most important being Fusarium thapsinum and Curvularia lunata. An additional 25 fungal genera are secondary invaders. Grain mold reduces the quantity of food available, as the fungus consumes a portion of the grain, and reduces the quality and economic value of what remains by producing pigments and toxins that make the grain less palatable and nutritious. Fusarium spp. and the secondarily invading Aspergillus spp. may produce toxins such as aflatoxins (a highly carcinogenic and …

Switchgrass For Forage And Bioenergy: I. Effects Of Nitrogen Rate And Harvest System, Maru Kering, J. T. Biermacher, Billy Cook, John A. Guretzky

Department of Agronomy and Horticulture: Faculty Publications

Switchgrass (Panicum virgatum L.) has been targeted for cellulosic ethanol production. Our objective was to evaluate effects of location, harvest system, and N fertilizer rates on switchgrass biomass yield and N, P, and K removal. Randomized complete block experiments with four replications were established on one-year old stands of ‘Alamo’ switchgrass at two Oklahoma locations in 2008. Harvest system and N rate interactions affected total annual yield. Biomass yields ranged from 9020 to 10530 kg/ha across harvest systems when no N was applied. With application of 179 kg N/ha, biomass yields averaged 10715, 13912, and 16516 kg/ha when harvested at …

Ecological Traits Of A New Aphid Parasitoid, Endaphis Fugitiva (Diptera: Cecidomyiidae), And Its Potential For Biological Control Of The Banana Aphid, Pentalonia Nigronervosa (Hemiptera: Aphididae), Frédéric B. Muratori, Raymond J. Gagne, Rusell H. Messing

USDA Systematic Entomology Laboratory

Most parasitoids of aphids are small wasps belonging to the families Braconidae or Aphelinidae. However, some dipteran parasitoids are also known to use aphids as hosts. We describe and give life-history information on a new species of aphid parasitoid, Endaphis fugitiva Gagné and Muratori, found to parasitize the banana aphid, Pentalonia nigronervosa Coquerel, the vector of banana bunchy top virus. Field and laboratory observations show that fly eggs are laid on the leaves near an aphid colony, the newly hatched fly larvae search for hosts while crawling on the leaf, and then penetrate the aphid between the legs and thorax. …

Journal of Women in Educational Leadership

The preparation of preservice administrators and teachers poses daunting challenges for the academy. Federal mandates associated with the No Child Left Behind Act (NCLB) and The Individuals with Disabilities Education Act (IDEA), and the pressure on school districts to produce high-perform- ing students despite inadequate financial resources, have shifted public ed- ucation's focus towards youth's academic proficiency. The linear focus has trumped the nurturing role school personnel could and should fulfill in ad- dition to scholastic achievement.

Foster care youth, in particular, validate the need for educational leaders who can nurture the overall emotional well-being of vulnerable children. The blase …

Nutrient And Fiber Type Relationships In Barrosã Muscles, P. Costa, L. C. Roseiro, V. Alves, Chris R. Calkins, R. J. B. Bessa, C. Santos

Department of Animal Science: Faculty Publications

Fiber type and nutrient compositions from Biceps femoris (Bf), Longissimus dorsi (Ld) and Supraspinatus (Ss) muscles of 10 Barrosã calves were determined and the respective relationships investigated by principal component analysis (PCA). The Ss muscle had higher proportion of type IIA fibers than Bf (P < 0.001) and Ld (P < 0.01), higher percentage of oxidative fibers than Ld muscle (P < 0.01) and lower proportion of IIB fibers than Bf (P P < 0.01). The latter muscle had higher intramuscular total lipids (ITL) (P P c9t11-CLA (P < 0.001), saturated fatty acids (SFA) (P < trans fatty acids (TFA) (P P P < n-6 PUFA (P < n-3 PUFA (P < 0.01), polyunsaturated/saturated fatty ac¬ids ratio (P/S) (P < 0.001) and hypocholesterolaemic/hypercholesterolaemic fatty acid ratio (h/H) (P P < and phospholipids (PL) (P < 0.05) contents were found in Ss muscle. Cholesterol amount was unaffected by anatomical location and ranged from 0.50 to 0.54 mg/g. Barrosã muscles were not well dis¬tinguishable by PCA since, based on fiber and nutritional compositions, they did not clearly present different pat¬terns. Barrosã-PDO veal is a low fat meat providing 367–558 mg of n-6 PUFA and 151-172 mg of n-3 PUFA of which 67–78 mg are EPA + DHA (based on 150 g consumption). The n-6 …
