Shifting The Load: Improving Bioscience Performance In Undergraduate Nurses Through Student Focused Learning, Angela Owens, Tracey Moroney May 2016

Shifting The Load: Improving Bioscience Performance In Undergraduate Nurses Through Student Focused Learning, Angela Owens, Tracey Moroney

Angela Owens

Background
Bioscience has a long history of being challenging to teach and learn within nursing courses and little has been published on new ways to assist students in their learning. The aim of this study was to determine which of three different interventions would assist student performance in a nursing bioscience unit.
Method
To begin, the contribution of recent prior learning in science was investigated by comparing the final exam marks of 182 students in the bioscience unit with the science marks they achieved at high (secondary) school. The effect of recent prior learning was then tested by investigating whether ...

In addition to the T2R bitter taste receptors, neuronal nicotinic acetylcholine receptors (nAChRs) have recently been shown to be involved in the bitter taste transduction of nicotine, acetylcholine and ethanol. However, at present it is not clear if nAChRs are expressed in enteroendocrine cells other than beta cells of the pancreas and enterochromaffin cells, and if they play a role in the synthesis and release of neurohumoral peptides. Accordingly, we investigated the expression and functional role of nAChRs in enteroendocrine STC-1 cells. Our studies using RT-PCR, qRT-PCR, immunohistochemical and Western blotting techniques demonstrate that STC-1 cells express several α and ...

Neurologists Look At Causes Of Baffling Brain Condition, Maggie Freleng Dec 2015

Neurologists Look At Causes Of Baffling Brain Condition, Maggie Freleng

Capstones

It can be hard getting help for someone with mental illness, but almost impossible when that person doesn't think they are sick. At at least half of people with schizophrenia, for example, insist that the voices they hear are real. People who do not know they are ill often refuse therapy and medication -- and their symptoms can spiral out of control. Doctors call this lack of awareness anosognosia. Neurologists are trying to discover what causes this baffling condition--and how to treat it.


Addition Of Berberine To 5-Aminosalicylic Acid For Treatment Of Dextran Sulfate Sodium-Induced Chronic Colitis In C57bl/6 Mice, Yan-Hong Li, Man Zhang, Hai-Tao Xiao, Hai-Bo Fu, Alan Ho, Chengyuan Lin, Yu Huang, Ge Lin, Zhaoxiang Bian Dec 2015

School of Chinese Medicine Journal Articles

Ulcerative colitis (UC) is a common chronic remitting disease but without satisfactory treatment. Alternative medicine berberine has received massive attention for its potential in UC treatment. Conventional therapies with the addition of berberine are becoming attractive as novel therapies in UC. In the present study, we investigated the preclinical activity of a conventional oral 5-aminosalicylic acid (5-ASA) therapy plus berberine in experimental colitis. A subclinical dose of 5-ASA (200 mg/kg/day) alone or 5-ASA plus berberine (20 mg/kg/day) was orally administered for 30 days to C57BL/6 mice with colitis induced by three cycles of 2% dextran ...

Principles Of Multidisciplinary Management, Richard S. Pieters, James Liebmann Dec 2015

Principles Of Multidisciplinary Management, Richard S. Pieters, James Liebmann

Cancer Concepts: A Guidebook for the Non-Oncologist

This chapter in Cancer Concepts: a Guidebook for the Non-Oncologist describes the principles of multi-disciplinary management, meaning multi-specialty physician management of malignancies. Tumor Boards are the model for multi-disciplinary management. They may be site specific or include the entire spectrum of malignancy. At Tumor Boards, staging workup and treatment recommendations are made collectively, and then the treatments are delivered by the respective modality specialists and their individual teams. Improved clinical decision making leading to superior survival for patients with some diseases and better quality of life has been documented with multi-disciplinary management. Just like curative patients, palliative patients require multi-disciplinary ...

Rapamycin Rescues Vascular, Metabolic And Learning Deficits In Apolipoprotein E4 Transgenic Mice With Pre-Symptomatic Alzheimer’S Disease, Ai-Ling Lin, Jordan B. Jahrling, Wei Zhang, Nicholas Derosa, Vikas Bakshi, Peter Romero, Veronica Galvan, Arlan Richardson

Sanders-Brown Center on Aging Faculty Publications

Apolipoprotein E ɛ4 allele is a common susceptibility gene for late-onset Alzheimer's disease. Brain vascular and metabolic deficits can occur in cognitively normal apolipoprotein E ɛ4 carriers decades before the onset of Alzheimer's disease. The goal of this study was to determine whether early intervention using rapamycin could restore neurovascular and neurometabolic functions, and thus impede pathological progression of Alzheimer's disease-like symptoms in pre-symptomatic Apolipoprotein E ɛ4 transgenic mice. Using in vivo, multimodal neuroimaging, we found that apolipoprotein E ɛ4 mice treated with rapamycin had restored cerebral blood flow, blood–brain barrier integrity ...


A Comparison Of Sign Searches, Live-Trapping, And Camera-Trapping For Detection Of American Badgers (Taxidea Taxus) In The Chihuahuan Desert, Robert L. Harrison Dec 2015

A Comparison Of Sign Searches, Live-Trapping, And Camera-Trapping For Detection Of American Badgers (Taxidea Taxus) In The Chihuahuan Desert, Robert L. Harrison

Western North American Naturalist

In communities where they occur, American badgers (Taxidea taxus) play important ecological, economic, and conservation roles. Central to understanding of badger ecology and management are estimates of badger population status. However, few studies have compared methods of detecting badgers for population surveys. I compared searches for burrows and diggings, live-trapping, and the use of automatic cameras at scent lures, bait stations, and anthropogenic permanent and temporary wildlife water sources in the Chihuahuan Desert of southern New Mexico. Searches for confirmed badger burrows and diggings yielded 0.14–0.88 detections per kilometer of transect. Badgers were trapped in 1.6 ...

Using Detection Dogs And Rspf Models To Assess Habitat Suitability For Bears In Greater Yellowstone, Jon P. Beckmann, Lisette P. Waits, Aimee Hurt, Alice Whitelaw, Scott Bergen

Western North American Naturalist

In the northern U.S. Rockies, including the Greater Yellowstone Ecosystem (GYE), connectivity is a concern because large carnivores have difficulties dispersing successfully between protected areas. One area of high conservation value because of its importance for connecting the GYE to wilderness areas of central Idaho is the Centennial Mountains and surrounding valleys (2500 km2) along the Idaho–Montana border just west of Yellowstone National Park. The current expansion of grizzly bears (Ursus arctos) and other large carnivore populations outside protected areas of Yellowstone National Park and Grand Teton National Park has placed a greater emphasis on potential linkage zones ...


Phenetic Analyses And Revised Classification Of The Ptelea Trifoliata Complex (Rutaceae), Erin Skornia, Muxi Yang, Wendy L. Applequist Dec 2015

Phenetic Analyses And Revised Classification Of The Ptelea Trifoliata Complex (Rutaceae), Erin Skornia, Muxi Yang, Wendy L. Applequist

Western North American Naturalist

The current classification of Ptelea divides the widespread and highly variable Ptelea trifoliata L. into 5 subspecies and 11 varieties, while additionally terming many specimens “intermediate.” Although there are visually observable differences among regional variants, principal component analyses of quantitative characters failed to separate subspecies or to even incompletely separate most varieties within subspecies. Some recognized subgroups are also not well distinguished by discontinuous qualitative characters. Where multiple varieties appear to be part of a single continuum of variation or are extremely similar, it is suggested that a reduction in the number of infraspecific taxa would improve the utility of ...


Facing A Changing World: Thermal Physiology Of American Pikas (Ochotona Princeps), Hans W. Otto, James A. Wilson, Erik A. Beever Dec 2015

Facing A Changing World: Thermal Physiology Of American Pikas (Ochotona Princeps), Hans W. Otto, James A. Wilson, Erik A. Beever

Western North American Naturalist

American pikas (Ochotona princeps) are of concern with respect to warming montane temperatures; however, little information exists regarding their physiological ability to adapt to warming temperatures. Previous studies have shown that pikas have high metabolism and low thermal conductance, which allow survival during cold winters. It has been hypothesized that these characteristics may be detrimental, given the recent warming trends observed in montane ecosystems. We examined resting metabolic rate, surface activity, and den and ambient temperatures (Ta) of pikas in late summer (August 2011 and 2012) at 2 locations in the Rocky Mountains. Resting metabolic rate was calculated to be ...


Production And Nutrient Content Of Two Shrub Species Related To Fire In Central Idaho, James M. Peek Dec 2015

Production And Nutrient Content Of Two Shrub Species Related To Fire In Central Idaho, James M. Peek

Western North American Naturalist

Nutrient content and weight of current year’s growth of Cercocarpus ledifolius Nuttall and Physocarpus malvaceus (Greene) Kuntze in central Idaho were obtained during early July in the years 1987–2007. The purpose of this work was to determine whether there was significant variation between years and whether mean monthly temperatures and total monthly precipitation could predict the variation. A wildfire in August 2000 causedP. malvaceus to vigorously resprout. Significant differences between years occurred for all nutrients for both species. October temperatures best predicted weight of current year’s growth in C. ledifolius, whereas prediction equations for nutrients involved ...


Maternity Roost Selection By Fringed Myotis In Colorado, Mark A. Hayes, Rick A. Adams Dec 2015

Maternity Roost Selection By Fringed Myotis In Colorado, Mark A. Hayes, Rick A. Adams

Western North American Naturalist

Fringed myotis (Myotis thysanodes) is a bat species of conservation concern in western North America that may be impacted by increased recreational activity near roost sites, changes in water resource availability caused by increased urban and agricultural water use, and anthropogenic climate change. Our purpose was to describe and model maternity roost use by fringed myotis in Colorado. We compared differences between roosts occupied by maternal fringed myotis and randomly selected potential roosting locations that were not known to be occupied by this species during the maternity period. We evaluated the strength of evidence for competing hypotheses on 2 scales ...

Life History, Burrowing Behavior, And Distribution Of Neohermes Filicornis (Megaloptera: Corydalidae), A Long-Lived Aquatic Insect In Intermittent Streams, Matthew R. Cover, Jeong Ho Seo, Vincent H. Resh

Western North American Naturalist

Several species of fishflies (Megaloptera: Corydalidae: Chauliodinae) have been reported from intermittent streams in western North America, but the life histories and distributions of these species are poorly understood. We studied the life history ofNeohermes filicornis (Banks 1903) for 2 years in Donner Creek (Contra Costa County, California), a small intermittent stream that flows for 5–7 months per year. Neohermes filicornis had a 3–4-year life span and larval growth was asynchronous. Analysis of gut contents showed that larvae were generalist predators of aquatic insect larvae including Diptera, Ephemeroptera, and Plecoptera. Final instars dug pupal chambers in the ...

Black-Tailed And White-Tailed Jackrabbits In The American West: History, Ecology, Ecological Significance, And Survey Methods, Matthew T. Simes, Kathleen M. Longshore, Kenneth E. Nussear, Greg L. Beatty, David E. Brown, Todd C. Esque

Western North American Naturalist

Across the western United States, Leporidae are the most important prey item in the diet of Golden Eagles (Aquila chrysaetos). Leporids inhabiting the western United States include black-tailed (Lepus californicus) and white-tailed jackrabbits (Lepus townsendii) and various species of cottontail rabbit (Sylvilagus spp.). Jackrabbits (Lepus spp.) are particularly important components of the ecological and economic landscape of western North America because their abundance influences the reproductive success and population trends of predators such as coyotes (Canis latrans), bobcats (Lynx rufus), and a number of raptor species. Here, we review literature pertaining to black-tailed and white-tailed jackrabbits comprising over 170 published ...

Computational And Experimental Determination Of The Hydrodynamics In A Stirred Unbaffled Vessel Provided With Angle-Mounted Axial Impellers, Ji Ma Dec 2015

Computational And Experimental Determination Of The Hydrodynamics In A Stirred Unbaffled Vessel Provided With Angle-Mounted Axial Impellers, Ji Ma

Theses

In most industrial applications, stirred tanks and reactors are typically provided with baffles to improve their mixing characteristics. However, in a number of pharmaceutical production facilities unbaffled vessels are commonly used. The absence of baffles is preferred in such cases because it reduces the potential for contamination and makes cleaning the vessel between batches easier. However, the lack of baffles also has a negative impact on the system’s hydrodynamics since it often results in poor mixing of the batch, especially if the impeller is centrally placed, since the liquid in such a system is subject to a strong tangential ...
