Student Physical Activity Patterns: Grade, Gender, And Activity Influences, Pamela Hodges Kulinna, Jeffrey J. Martin, Qin Lai, Amy Kliber, Brett Reed

Kinesiology, Health and Sport Studies

The purpose of this study was to determine how physical education students' cardiovascular responses as determined by mean heart rate, standard deviation of heart rate, and percentage of time in target heart rate zone varied according to student characteristics. Participants were 505 students in Grades 3 through 12. The Polar Accurex Plus heart rate telemetry system was used to measure the physiological load on the cardiovascular system. Three-way ANOVA results suggested that heart rate patterns in physical education varied according to gender, grade, and activity. For example, secondary school girls were more active in individual activities while secondary school boys …

Acute Cardiovascular Response And Perception Of Effort Between The Super Slow And Gold Standard Resistance Training Protocols, Phillip Wickwire

Masters Theses & Specialist Projects

Super Slow training was proposed by Ken Hutchins in a book entitled Super Slow: The Ultimate Exercise Protocol (1992). Since then Super Slow training has been proposed to improve strength more effectively than traditional resistance training and improve cardiovascular measures above aerobic exercise. However, whether this type of training is safe for the older, possibly hypertensive population to which it is being targeted is questionable. To help provide an answer to this question the purpose of this study was to measure blood pressure, heart rate (HR), and ratings of perceived exertion (RPE) while performing the Super Slow resistance training protocol …

In Vitro Regeneration And Genetic Transformation Of Sesbania Drummondii: A Medicinally And Environmentally Important Plant, Satish Cheepala

Masters Theses & Specialist Projects

This study describes rapid propagation of Sesbania drummondii using nodal explants isolated from seedlings and young plants. The nodal segments proliferated into multiple shoots on Murashige and Skoog (MS) medium supplemented with 22.2 /M benzyladenine. Murashige and Skoog medium containing 2.2 and 4.5 //M thidiazuron induced 5 - 6 healthier shoots per axillary node from 3-month-old plants. Nodal segments cultured on MS medium containing combinations of benzyladenine (8.8 and 11.1 /JM) and either indole-3-butyric acid (0.24 - 2.46 //M) or indole-3-acetic acid (0.28 - 2.85 //M) produced fewer shoots. Callus when subcultured on 2.2 /LihA thidiazuron containing medium resulted in …

Crystal Structure Of The Sars Protein From Staphylococcus Aureus, Ronggui Li, Adhar C. Manna, Shaodong Dai, Ambrose L. Cheung, Gongyi Zhang

Dartmouth Scholarship

The expression of virulence determinants in Staphylococcus aureus is controlled by global regulatory loci (e.g., sarA and agr). One of these determinants, protein A (spa), is activated by sarS, which encodes a 250-residue DNA-binding protein. Genetic analysis indicated that the agr locus likely mediates spa repression by suppressing the transcription of sarS. Contrary to SarA and SarR, which require homodimer formation for proper function, SarS is unusual within the SarA protein family in that it contains two homologous halves, with each half sharing sequence similarity to SarA and SarR. Here we report the 2.2 Å …

Effectiveness Of A Practice Regimen For Decreasing Floor Rise Time In Older Adults, Deborah Waldschmidt Gibbs

Human Movement Studies & Special Education Theses & Dissertations

Some older adults experience extended periods of time lying on the floor waiting for help to arrive because they can not rise up independently (Campbell et al., 1990; Nevitt, Cummings, and Hudes, 1991). In many of these cases the older adults are not seriously injured, yet they lack the ability to rise up (Tinetti and Speechley, 1989; Vellas, Cayla, Bocquet, Pemille, and Albarede, 1987). Body Recall, an exercise program that teaches floor rising to older adults, advocates practicing getting up from the floor as a method for retaining this ability. The benefit of Body Recall is only anecdotal and has …

Do Fishes Have Nociceptors? Evidence For The Evolution Of A Vertebrate Sensory System, Lynne U. Sneddon, Victoria A. Braithwaite, Michael J. Gentle

Veterinary Science and Medicine Collection

Nociception is the detection of a noxious tissue-damaging stimulus and is sometimes accompanied by a reflex response such as withdrawal. Pain perception, as distinct from nociception, has been demonstrated in birds and mammals but has not been systematically studied in lower vertebrates. We assessed whether a fish possessed cutaneous nociceptors capable of detecting noxious stimuli and whether its behavior was sufficiently adversely affected by the administration of a noxious stimulus. Electrophysiological recordings from trigeminal nerves identified polymodal nociceptors on the head of the trout with physiological properties similar to those described in higher vertebrates. These receptors responded to mechanical pressure, …

Interaction Between Adrenergic And Nitric Oxide-Releasing Nerves In Cerebral Arteries, Emmanuel Ngu Mbaku

Loma Linda University Electronic Theses, Dissertations & Projects

Of all body tissues, the brain is the least tolerant of ischemia so much that interruption of cerebral blood flow by 5 sec can cause syncope, with irreversible tissue damage if the ischemia last a few minutes. In this respect, the body has an imperative duty of ensuring constant and adequate blood supply to the brain. It does so through a series of intrinsic and extrinsic control factors of which adrenergic and nitric oxide-releasing nerves are components. My research examined the interaction between these two nerve-types with emphasis on the mechanisms involved as well as on changes in their functions …

Distraction Osteogenesis In Edentulous Alveolar Bone With Rhbmp-2 Enhancement, Liviu F. Eftimie

Loma Linda University Electronic Theses, Dissertations & Projects

Distraction osteogenesis, a unique system of affecting rapid bone healing in fractures, realigning malformed bones, and lengthening congenitally short and traumatically shortened bones has become an increasingly utilized technique for the maxillofacial region. The use of distraction osteogenesis has been described for increasing the height of edentulous mandibular alveolar ridges while concurrently forming new bone within the ridge to allow for adequate reconstruction. A standard protocol for performing distraction osteogenesis in the maxillofacial region has been well documented in the literature. Standard distraction osteogenesis requires an initial surgery to place the distraction osteogenesis device and mobilize the segment to be …

Potential Mechanisms Explaining The Antitumor Effect Of Total-Body Irradiation, Glen Michael Miller

Loma Linda University Electronic Theses, Dissertations & Projects

While numerous reports have documented that radiation exposure increases the risk for malignancy and suppresses immune mechanisms, increasing evidence has suggested that low-dose total-body irradiation (TBI) may alter leukocyte composition and function leading to heightened immune responsiveness and long-term remission of certain cancers. Having observed that moderate-dose TBI produces an antitumor effect in the Lewis lung carcinoma (EEC) model, the major goal of this study was to determine whether changes in tumor growth could be correlated with radiation-induced alterations of immune system parameters. The governing hypothesis was that selective immune augmentation, i.e. upregulation of specific leukocyte subsets, is primarily responsible …

Trigeminal Somatosensory Innervation Of The Head Of A Teleost Fish With Particular Reference To Nociception, Lynne U. Sneddon

Veterinary Science and Medicine Collection

Trigeminal somatosensory receptors have not been characterised in teleost fish and studies in elasmobranchs have failed to identify nociceptors. The present study examined the trigeminal nerve of a teleost fish, the rainbow trout (Oncorhynchus mykiss) to determine what types of somatosensory receptors were present on the head of the trout specifically searching for nociceptors. Single unit recordings were made from receptive fields on the head of the fish innervated by the trigeminal nerve. Each receptive field was tested for sensitivity to mechanical, thermal and chemical stimulation. Five different receptor types were found: fast adapting receptors responding to mechanical stimulation; slowly …

Photodynamic Therapy, Ashley Thomas

McCabe Thesis Collection

Photodynamic therapy is a new treatment that is being introduced into the veterinary community. Photodynamic therapy is the use of light activated chemotherapy to kill cancer cells (Dougherty, 1998). It has already been approved by the US Food and Drug Administration to be used as a form of cancer treatment in humans, but has not been carried over to the veterinary community. That is until now. Photodynamic therapy is now being tested in the veterinary community in hopes to find the same results that the human medical community has when dealing with certain types of cancer. They also hope to …

Genomic And Proteomic Profiling Of Responses To Toxic Metals In Human Lung Cells, Angeline S. Andrew, Amy J. Warren, Aaron Barchowsky, Kaili A. Temple, Linda Klei, Nicole V. Soucy, Kimberly A. O'Hara, Joshua W. Hamilton

Dartmouth Scholarship

Examining global effects of toxic metals on gene expression can be useful for elucidating patterns of biological response, discovering underlying mechanisms of toxicity, and identifying candidate metal-specific genetic markers of exposure and response. Using a 1,200 gene nylon array, we examined changes in gene expression following low-dose, acute exposures of cadmium, chromium, arsenic, nickel, or mitomycin C (MMC) in BEAS-2B human bronchial epithelial cells. Total RNA was isolated from cells exposed to 3 M Cd(II) (as cadmium chloride), 10 M Cr(VI) (as sodium dichromate), 3 g/cm2 Ni(II) (as nickel subsulfide), 5 M or 50 M As(III) (as sodium arsenite), or …

Lysosomal Membrane Permeabilization Induces Cell Death In A Mitochondrion-Dependent Fashion, Patricia Boya, Karine Andreau, Delphine Poncet, Naoufal Zamzami, Jean-Luc Perfettini, Didier Metivier, David M. Ojcius, Marja Jäättelä, Guido Kroemer

All Dugoni School of Dentistry Faculty Articles

A number of diseases are due to lysosomal destabilization, which results in damaging cell loss. To investigate the mechanisms of lysosomal cell death, we characterized the cytotoxic action of two widely used quinolone antibiotics: ciprofloxacin (CPX) or norfloxacin (NFX). CPX or NFX plus UV light (NFX*) induce lysosomal membrane permeabilization (LMP), as detected by the release of cathepsins from lysosomes. Inhibition of the lysosomal accumulation of CPX or NFX suppresses their capacity to induce LMP and to kill cells. CPX- or NFX-triggered LMP results in caspase-independent cell death, with hallmarks of apoptosis such as chromatin condensation and phosphatidylserine exposure on …

Alpha-Toxin Is Required For Biofilm Formation By Staphylococcus Aureus, Nicky C. Caiazza, George A. O'Toole

Dartmouth Scholarship

Staphylococcus aureus is a common pathogen associated with nosocomial infections. It can persist in clinical settings and gain increased resistance to antimicrobial agents through biofilm formation. We have found that alpha-toxin, a secreted, multimeric, hemolytic toxin encoded by the hla gene, plays an integral role in biofilm formation. The hla mutant was unable to fully colonize plastic surfaces under both static and flow conditions. Based on microscopy studies, we propose that alpha-hemolysin is required for cell-to-cell interactions during biofilm formation.

Studies On The Regulation Of Mu Opioid Receptor Mrna Expression In Shsy-5y Human Neuroblastoma Cells, Xin Yu

Seton Hall University Dissertations and Theses (ETDs)

Prolonged exposure to morphine down-regulates mu opioid receptors (MOR) on both undifferentiated and differentiated (retinoic acid or phorbol ester treated) SHSY-5Y cells. However, morphine pretreatment does not alter MOR receptor affinity for morphine. To investigate the molecular basis for MOR regulation after exposure to its selective agonists, we have developed a quantitative competitive reverse transcriptase-polymerase chain reaction (QC-RT PCR) to quantify the expression of MOR in SHSY-SY cells. Differentiation of SHSY-5Y cells with retinoic acid or phorbol ester up regulated MOR mRNA expression by 30 % and 78%, respectively. A 24 hours treatment with morphine (10 µM) down regulated MOR …

The Effect Of Local Muscle Fatigue On The Threshold Frequency Of An Electrically Induced Cramp, Marcus B. Stone

All-Inclusive List of Electronic Theses and Dissertations

Context: Muscle fatigue has been implicated as a factor in the cause of exercise associated muscle cramping. In an electrically induced muscle cramp, threshold frequency (TF) is the frequency of stimulation at which the cramp originates. Therefore, the TF of a fatigued muscle should shift from a previously established baseline. Objective: To determine the effect of local muscle fatigue on TF of electrically induced muscle cramp. Design: A 2 X 2 repeated measures design was used for this study. The independent variables were test (pre- and post-) and condition (control and fatigue). The dependent variable was TF of an electrically …

The Development Of A Physical Education Teachers' Physical Activity Self-Efficacy Instrument, Jeffrey J. Martin, Pamela Hodges Kulinna

Kinesiology, Health and Sport Studies

In the present investigation a questionnaire was developed to assess physical education teachers' self-efficacy for teaching classes in which their students were engaged in high levels of physical activity (i.e., at least 50% of class time). Exploratory and confirmatory factor analyses resulted in the development of a 16-item, 4-factor, multidimensional physical education teachers' physical activity self-efficacy scale (PETPAS) that produced reliable and valid scores. The Student factor reflected teachers' efficacy for managing students who didn't enjoy or value physical activity. The Time factor was indicative of teachers' efficacy when they didn't have enough time to teach. The Space factor reflected …

Expression Of Glutathione-S-Transferase Mu 1 (Gstm1) And Glutathione-S-Transferase Theta 1 (Gstt1) In Patients With Aplastic Anemia And Myelodysplastic Syndromes, Aaron Conrad Spivey

Theses and Dissertations in Biomedical Sciences

Aplastic Anemia is a disorder of the hematopoietic bone marrow stem cells that is frequently associated with drug or chemical exposures. Reduced ability to detoxify drugs or chemicals may result in an increased risk of disease. Glutathione S-transferases are Phase II enzymes, which help detoxify xenobiotics. Many patients who have developed aplastic anemia and myelodysplastic syndrome have the null genotype for GSTMI and/or GSTTI. For patients with GSTMI and GSTTI positive genotypes, non-expression of these enzymes may cause an increased risk in developing aplastic anemia or myelodysplastic syndrome. To test whether genotype positive patients have GSTMI or GSTTI null …

Characterization Of Mouse Prostate Tumor-Infiltrating Leukocytes, Daniel Alan Holterman

Theses and Dissertations in Biomedical Sciences

Prostate cancer is the most common form of non-cutaneous cancer among men in the United States and the second most common cause of cancer-related death among men with approximately 189,000 new cases diagnosed and 30,200 deaths of the disease in 2002. Prostate cancer can be a treatable disease but once it becomes metastatic there are no acceptable therapies. For this reason, immunotherapy has been attempted but the results have been disappointing. The TRAMP model was used to evaluate specific interactions between an intact murine immune system and a prostate tumor that expressed a naturally processed weak tumor antigen. Vaccination trials …
