Implementing A Fundamental Movement Skill Program In An Early Childhood Setting: The Teachers’ Perspectives, Marie Martin, Beth P. Hands Jan 2003

Implementing A Fundamental Movement Skill Program In An Early Childhood Setting: The Teachers’ Perspectives, Marie Martin, Beth P. Hands

Health Sciences Papers and Journal Articles

The place of explicit movement skill development programs in early childhood settings is contentious. However given the growing understanding that movement competence is important for maintaining an active and healthy lifestyle (Hands, Parker, & Larkin, 2001), well planned and effective programs specifically designed for young children are important.

In this paper, the influence of a new teaching resource designed to support teachers in implementing a fundamental movement skill program is presented using a case study approach. The case studies were constructed with teachers working in a range of early childhood settings. The impact of the program on teachers’ level of …


Antipyretic, Parasitologic, And Immunologic Effects Of Combining Sulfadoxine/Pyrimethamine With Chloroquine Or Paracetamol For Treating Uncomplicated Plasmodium Falciparum Malaria, E. Hugosson, D. Tarimo, M. Troye-Blomberg, S.M. Montgomery, Zul Premji, A. Bjorkman Jan 2003

Antipyretic, Parasitologic, And Immunologic Effects Of Combining Sulfadoxine/Pyrimethamine With Chloroquine Or Paracetamol For Treating Uncomplicated Plasmodium Falciparum Malaria, E. Hugosson, D. Tarimo, M. Troye-Blomberg, S.M. Montgomery, Zul Premji, A. Bjorkman

Pathology, East Africa

Sulfadoxine/pyrimethamine (SP) is increasingly used against malaria in sub-Saharan Africa because of chloroquine resistance. However, chloroquine may have a beneficial antipyretic effect. We therefore compared the combination of SP plus chloroquine, chloroquine alone, SP alone, and SP plus paracetamol in the treatment of uncomplicated Plasmodium falciparum malaria in 175 Tanzanian children (1-4 years old) in a randomized trial. Outcome variables were axillary temperatures every six hours, daily parasitemias, and serum levels of IgG antibodies to P. falciparum. Lower mean temperatures (6-48 hours) were achieved with SP plus chloroquine or paracetamol than with SP alone (P < 0.001) or chloroquine alone (P < 0.05). All three SP-treated groups showed high and similar parasite reduction (0-48 hours), whereas treatment with chloroquine alone was much less effective. Levels of IgG antibodies to P. falciparum increased significantly (P < 0.001) and similarly in the four treatment groups between days 0, 2. and 3. Thus, the addition of chloroquine or paracetamol to SP improved the clinical outcome, but did not affect the parasitologic response or antibody production.


Role Of Neuropoietic Cytokines In Development And Progression Of Diabetic Polyneuropathy: From Glucose Metabolism To Neurodegeneration, Dusanka S. Skundric, Robert P. Lisak Jan 2003

Role Of Neuropoietic Cytokines In Development And Progression Of Diabetic Polyneuropathy: From Glucose Metabolism To Neurodegeneration, Dusanka S. Skundric, Robert P. Lisak

Neurology Faculty Publications

Diabetic neuropathy develops as a result of hyperglycemia- induced local metabolic and microvascular changes in both type I and type II diabetes mellitus. Diabetic neuropathy shows slower impulse conduction, axonal degeneration, and impaired regeneration. Diabetic neuropathy affects peripheral, central, and visceral sensorimotor and motor nerves, causing improper locomotor and visceral organ dysfunctions. The pathogenesis of diabetic neuropathy is complex and involves multiple pathways. Lack of success in preventing neuropathy, even with successful treatment of hyperglycemia, suggests the presence of early mediators between hyperglycemia-induced metabolic and enzymatic changes and functional and structural properties of Schwann cells (SCs) and axons. It is …

Clinical Practice Guidelines For The Management Of Ischemic Stroke In Pakistan, Saad Shafqat Jan 2003

Clinical Practice Guidelines For The Management Of Ischemic Stroke In Pakistan, Saad Shafqat

Section of Neurology

Ischemic stroke represents a huge global burden, being the leading cause of physical disability and the third leading cause of death worldwide1. Although rigorous epidemiological data from Pakistan are lacking, stroke is certainly the commonest reason for admission to a neurology ward in our part of the world, as elsewhere. Recent years have seen a number of new developments in the clinical approach to stroke, including in the areas of diagnostic work-up, acute treatment and secondary prevention. These developments enable the formulation of clinical practice guidelines for achieving standardized management of ischemic stroke, with the overall aini of …

For individual city analysis, generalised additive models extending …


Elastomeric Hoof Boots, John Hanley Jan 2003

Elastomeric Hoof Boots, John Hanley

Masters

The design, manufacture and testing of a prototype elastomeric equine boot is described in this thesis. Thoroughbred horses may suffer from a number of serious hoof disorders. These include stone bruising, navicular syndrome and hoof wall separation. Excessive concussion in the equine hoof is a major contributory factor in most of the problems horses experience in their lower limbs. Bandaging of a horses foot after injury is time consuming as well as being labour intensive. The proposed boot serves a number of purposes; by replacing bandages during poulticing it plays a part in faster healing of foot ailments. It can …

On Vs. Off: Coronary Bypass Surgery From A Patient's Perspective, Ann Steele Jan 2003

On Vs. Off: Coronary Bypass Surgery From A Patient's Perspective, Ann Steele

Honors Projects

Throughout the years, technological advances have changed the face of cardiac surgery, but at times, it is a return to a previous technique, which proves beneficial. Prior to the introduction of cardiopulmonary bypass, cardiac surgery was performed on a beating heart, but due to the lack of an appropriate immobilizing device, the surgery was extremely complicated. With the introduction of new stabilization devices, immobilization of the heart has become easier and beating heart surgery has gained popularity once again. Multiple studies have been done which discuss the benefits of off-pump coronary artery bypass surgery (OPCAB), but none of the studies …

In this paper, the influence of a new teaching resource designed to support teachers in implementing a fundamental movement skill program on the children in the classes is presented using a case study approach. The case studies were constructed with teachers and children in a range of early childhood settings. The impact of the program on the children’s level of confidence, knowledge …


Evidence For The Involvement Of A Tsetse Midgut Lectin-Trypsin Complex In Differentiation Of Bloodstream-Form Trypanosomes, L. U. Abubakar, G. Zimba, C. Wells, F. Mulaa, E. O. Osir Jan 2003

Evidence For The Involvement Of A Tsetse Midgut Lectin-Trypsin Complex In Differentiation Of Bloodstream-Form Trypanosomes, L. U. Abubakar, G. Zimba, C. Wells, F. Mulaa, E. O. Osir

All Peer-Reviewed Publications

We have previously described a bloodmeal-induced molecule (lectin-trypsin complex) from the midgut of the tsetse fly, Glossina longipennis, with both lectin and trypsin activities (Osir et al., 1995). In this paper, we report on the isolation of a similar molecule from the midguts of Glossina fuscipes fuscipes and provide direct evidence for its involvement in the development of African trypanosomes. The molecule (native Mr ∼65,700) has two non-covalently linked subunits, Mr ∼28,800 and Mr ∼35,700. The native molecule was found to be capable of inducing differentiation of bloodstream-form trypanosomes into procyclic (midgut forms) in vitro. In the assays, specific antibodies …


Comparison Of Keorolac With Morphine For Intraoperative Analgesia In Patients Undergoing Total Abdominal Hysterectomy, S. S. Hasan, Fazal Hameed Khan, M. Ahmed Jan 2003

Comparison Of Keorolac With Morphine For Intraoperative Analgesia In Patients Undergoing Total Abdominal Hysterectomy, S. S. Hasan, Fazal Hameed Khan, M. Ahmed

Department of Anaesthesia

Direct laryngoscopy and endotracheal intubation during anaesthesia and cutting, stretching and tissue manipulation during surgery is the most painful time for a patient undergoing surgery. The elicited pain during a surgical procedure is associated with significant hemodynamic changes including rise in blood pressure, heart rate, sweating, pupillary dilatation etc. These hemodynamic changes are not desirable and may produce deleterious effects in patients with hypertension, ischemic heart disease and cerebro-vascular disease and impose a great challenge for anaesthesiologist to maintain physiologic homeostasis during these periods of stress. Opioids are considered to be the corner stone in the management of intraoperative and …

Development And Validation Of A Professional Behavior Assessment., Kristie Koenig, Caryn Johnson, Cathleen K Morano, Joseph P Ducette

Department of Occupational Therapy Faculty Papers

Allied health students must quickly socialize into a professional role as they transition from classroom to clinic. In addition to skill development, students must exhibit a host of professional behaviors that facilitate successful interaction with patients, families, and colleagues. There is a need for a valid, reliable assessment of professional behaviors that contribute to clinical competence. This study reports on the development and validation of a professional behavior assessment for occupational therapy students on a part-time clinical rotation (Level I). The Philadelphia Region Fieldwork Consortium (PRFC) Level I Student Evaluation was developed from an initial survey (n = 75) to …


Federalism And The Future Of Health Care Reform, Richard Briffault, Sherry Glied Jan 2003

Federalism And The Future Of Health Care Reform, Richard Briffault, Sherry Glied

Faculty Scholarship

An important theme in the ongoing health care reform debate is federalism. During the battle over the Clinton Health Plan in 1993–94, the question of which level of government — federal or state — should take the leading role in health policy was almost as contentious as the particular proposals for extending access to quality health care and controlling health care costs. With the failure in 1994 to achieve comprehensive legislation at the national level, many policymakers and commentators gave fresh attention to the states as potential agents for health care reform.


The Influence Of Slow Calcium-Activated Potassium Channels On Epileptiform Activity In A Neuronal Model Of Pyramidal Cells, Keun-Hang Susan Yang, Piotr J. Franaszczuk, Gregory K. Bergey Jan 2003

The Influence Of Slow Calcium-Activated Potassium Channels On Epileptiform Activity In A Neuronal Model Of Pyramidal Cells, Keun-Hang Susan Yang, Piotr J. Franaszczuk, Gregory K. Bergey

Mathematics, Physics, and Computer Science Faculty Articles and Research

An imbalance between excitation and inhibition can play an important role in the generation of epileptiform activity. Experimental evidence indicates that alterations of either synaptic activity or intrinsic membrane properties may contribute to this imbalance. The slow Ca2+ - activated K+ currents (sIAHP) limit neuronal firing rate and excitability and are therefore of great interest for their potential role in epileptogenesis. The sIAHP is found in both excitatory and inhibitory neurons, and its effect on these neurons can influence the network behavior. Simulations show that the increased excitability caused by reduction of inhibition by the sIAHP for inhibitory interneuron generates …

The Politics Of Public Health: A Response To Epstein, Lawrence O. Gostin, Maxwell Gregg Bloche Jan 2003

The Politics Of Public Health: A Response To Epstein, Lawrence O. Gostin, Maxwell Gregg Bloche

Georgetown Law Faculty Publications and Other Works

Conservatives are taking aim at the field of public health, targeting its efforts to understand and control environmental and social causes of disease. Richard Epstein and others contend that these efforts in fact undermine people’s health and well-being by eroding people’s incentives to create economic value. Public health, they argue, should stick to its traditional task—the struggle against infectious diseases. Because markets are not up to the task of controlling the transmission of infectious disease, Epstein says, coercive government action is required. But market incentives, not state action, he asserts, represent our best hope for controlling the chronic illnesses that …

Identification Of Novel Domains Within Sox-2 And Sox-11 Involved In Autoinhibition Of Dna Binding And Partnership Specificity, Matthew S. Wiebe, Tamara K. Nowling, Angie Rizzino Jan 2003

Identification Of Novel Domains Within Sox-2 And Sox-11 Involved In Autoinhibition Of Dna Binding And Partnership Specificity, Matthew S. Wiebe, Tamara K. Nowling, Angie Rizzino

Nebraska Center for Virology: Faculty Publications

Sox transcription factors play key regulatory roles throughout development, binding DNA through a consensus (A/T)(A/T)CAA(A/T)G sequence. Although many different Sox proteins bind to this se-quence, it has been observed that gene regulatory elements are commonly responsive to only a small subset of the entire family, implying that regulatory mechanisms exist to permit selective DNA bind-ing and/or transactivation by Sox family members. To identify and explore the mechanisms modu-lating gene activation by Sox proteins further, we compared the function of Sox-2 and Sox-11. This led to the discovery that Sox proteins are regulated differentially at multiple levels, including trans-activation, protein partnerships …

Structural Analyses Of Phycodnaviridae And Iridoviridae, Alan A. Simpson, Narayanasamy Nandhagopal, James L. Van Etten, Michael G. Rossmann

Nebraska Center for Virology: Faculty Publications

The Phycodnaviridae, Iridoviridae and related viruses, with diameters of 1500±2000 A Ê , are formed from large trigonal arrays of hexagonally close-packed capsomers forming the faces of icosahedra [Yan et al. (2000), Nature Struct. Biol. 7, 101-103; Nandhagopal et al. (2002), Proc. Natl Acad. Sci. USA, 99, 14758-14763]. Caspar and Klug predicted that such structures could be assembled from hexameric capsomers [Caspar & Klug (1962), Cold Spring Harbor. Symp. Quant. Biol. 27, 1-24], as was subsequently found in numerous icosahedral viruses. During the course of evolution, some viruses, including the virus families …

Roles Of Mycobacterium Smegmatis D-Alanine:D-Alanine Ligase And D-Alanine Racemase In The Mechanisms Of Action Of And Resistance To The Peptidoglycan Inhibitor D-Cycloserine, Zhengyu Feng, Raul G. Barletta

School of Veterinary and Biomedical Sciences: Faculty Publications

D-Cycloserine (DCS) targets the peptidoglycan biosynthetic enzymes D-alanine racemase (Alr) and Dalanine: D-alanine ligase (Ddl). Previously, we demonstrated that the overproduction of Alr in Mycobacterium smegmatis determines a DCS resistance phenotype. In this study, we investigated the roles of both Alr and Ddl in the mechanisms of action of and resistance to DCS in M. smegmatis. We found that the overexpression of either the M. smegmatis or the Mycobacterium tuberculosis ddl gene in M. smegmatis confers resistance to DCS, but at lower levels than the overexpression of the alr gene. Furthermore, a strain overexpressing both the alr and ddl …


Herpes Simplex Virus Type 1 And Bovine Herpesvirus 1 Latency, Clinton J. Jones Jan 2003

Herpes Simplex Virus Type 1 And Bovine Herpesvirus 1 Latency, Clinton J. Jones

School of Veterinary and Biomedical Sciences: Faculty Publications

A high percentage of the world’s population are infected with herpes simplex virus type 1 (HSV-1), and infection can cause a variety of disorders (35, 187). Recurrent ocular HSV-1 is the leading cause of infectious corneal blindness in industrialized nations (190). In a murine model, ocular infection induces autoimmune disorders, leading to corneal antigen destruction and stromal keratitis (275). HSV-1 infections also cause gastrointestinal disorders, esophageal disorders, and approximately 25% of the genital herpes infections (67, 158). HSV-1 infections can cause sporadic encephalitis, but this is relatively rare compared to other diseases resulting from infection. Further evidence for its involvement …

School of Veterinary and Biomedical Sciences: Faculty Publications

Nearly all human immunodeficiency virus (HIV) infections are acquired mucosally, and the gut-associated lymphoid tissues are important sites for early virus replication. Thus, vaccine strategies designed to prime virus-specific cytotoxic T lymphocyte (CTL) responses that home to mucosal compartments may be particularly effective at preventing or containing HIV infection. The Salmonella type III secretion system has been shown to be an effective approach for stimulating mucosal CTL responses in mice. We therefore tested ∆phoP-phoQ attenuated strains of Salmonella enterica serovar Typhimurium and S. enterica serovar Typhi expressing fragments of the simian immunodeficiency virus (SIV) Gag protein fused to the …

Animal Anti-Apoptotic Genes Ameliorate The Loss Of Turgor In Water-Stressed Transgenic Tobacco, Tala Awada, D. D. Dunigan, M. B. Dickman

Nebraska Center for Virology: Faculty Publications

Nicotiana tabacum L. ‘Glurk’ plants were transformed with antiapoptotic animal genes [chicken Bcl-xl; nematode CED-9; chicken Bcl-xl(GA) a mutant of Bcl-xl; and a 3’ non-coding region of human Bcl-2, referred to as 161-1]. Our objectives were to determine whether plant transformation with anti-apoptotic genes ameliorates drought tolerance in tobacco plants by subjecting the plants to a dry-down period. The non-transformed Glurk and the transgenic Glurk harboring G115, which expresses β-glucuronidase, served as controls. Transformation of tobacco plants with animal anti-apoptotic genes significantly impacted the rates of photosynthesis (A) and stomatal conductance (gs), but not to the same extent …
