Subclavian Vein Stenosis/Occlusion Following Transvenous Cardiac Pacemaker And Defibrillator Implantation: Incidence, Pathophysiology And Current Management, Brian O'Leary, Suhail Allaqaband

Journal of Patient-Centered Research and Reviews

Subclavian vein stenosis is a common, but usually asymptomatic, complication following cardiac device placement. In addition to reviewing the literature on incidence, pathogenesis and management options for this important clinical problem, we describe two cases of symptomatic subclavian vein occlusion following pacemaker/defibrillator placement and successful treatment with venoplasty and stenting.


Overview Of The Role Of Duplex Ultrasound For Treatment And Surveillance Of Peripheral Arterial Disease, John H. Fish III, Peter Klein-Weigel, Gustav Fraedrich 2015 Jobst Vascular Institute

Overview Of The Role Of Duplex Ultrasound For Treatment And Surveillance Of Peripheral Arterial Disease, John H. Fish Iii, Peter Klein-Weigel, Gustav Fraedrich

Journal of Patient-Centered Research and Reviews

Imaging strategies for preinterventional planning in symptomatic peripheral artery disease have employed various modalities ranging from duplex ultrasound to noninvasive angiography with computed tomography (CT) or magnetic resonance (MRA). These methods have classically been compared to the gold standard of digital subtraction angiography and are reviewed here in detail through the work of relevant published studies and meta-analyses between 1996 and 2014. In particular, we focus on the diagnostic performance, reproducibility and cost-effectiveness of these aforementioned modalities with respect to mapping the lower extremity arterial tree for planning vascular intervention and surveillance. The data presented suggests comparable sensitivity and specificity ...

Novel Oral Anticoagulants For Stroke Prophylaxis And Venous Thromboembolism Prevention And Treatment, Laith G. Alsayegh

Journal of Patient-Centered Research and Reviews

Novel oral anticoagulants (NOACs) are becoming popular management options for stroke prophylaxis in nonvalvular atrial fibrillation as well as deep vein thrombosis and pulmonary embolism treatment and prophylaxis. NOACs have similar efficacy to warfarin along with noninferior safety profiles. Patient comorbidities, size, renal and hepatic function, and concomitant drug regimen play a role in which NOAC a physician may choose.


Thymic Involution Perturbs Negative Selection And Leads To Chronic Inflammation, Brandon D. Coder B.S. 2015 University of North Texas Health Science Center at Fort Worth

Thymic Involution Perturbs Negative Selection And Leads To Chronic Inflammation, Brandon D. Coder B.S.

Theses and Dissertations

The ubiquitous presence of chronic low-level pro-inflammatory factors in elderly individuals (termed inflammaging) is a significant risk factor for morbidity and mortality. The etiology of inflammaging is largely unknown. Recent evidence has identified the persistent activation of immune cells, thought to arise from latent viral infections, as key contributors towards the development of a chronic inflammatory environment. However, the contribution of autoreactive T cells towards the development of inflammaging has yet to be investigated. Another pervasive feature of the aging process is the age-related involution of the thymus gland, which has been linked with a predisposition toward developing autoimmunity. In ...

Negative Skeletal Effects Of Locally Produced Adiponectin, Marcia J. Abbott, Theresa M. Roth, Linh Ho, Liping Wang, Dylan O'Carroll, Robert A. Nissenson

Health Sciences and Kinesiology Faculty Articles

Epidemiological studies show that high circulating levels of adiponectin are associated with low bone mineral density. The effect of adiponectin on skeletal homeostasis, on osteoblasts in particular, remains controversial. We investigated this issue using mice with adipocyte-specific over-expression of adiponectin (AdTg). MicroCT and histomorphometric analysis revealed decreases (15%) in fractional bone volume in AdTg mice at the proximal tibia with no changes at the distal femur. Cortical bone thickness at mid-shafts of the tibia and at the tibiofibular junction was reduced (3–4%) in AdTg mice. Dynamic histomorphometry at the proximal tibia in AdTg mice revealed inhibition of bone formation ...

Introduction

Basal-like breast cancer (BLBC) is an aggressive subtype often characterized by distant metastasis, poor patient prognosis, and limited treatment options. Therefore, the discovery of alternative targets to restrain its metastatic potential is urgently needed. In this study, we aimed to identify novel genes that drive metastasis of BLBC and to elucidate the underlying mechanisms of action.

Methods

An unbiased approach using gene expression profiling of a BLBC progression model and in silicoleveraging of pre-existing tumor transcriptomes were used to uncover metastasis-promoting genes. Lentiviral-mediated knockdown of interleukin-13 receptor alpha 2 (IL13Ralpha2) coupled with whole-body in vivo bioluminescence imaging was ...

Multiple myeloma (MM) is an incurable clonal plasma cell malignancy. Because of a high rate of immunoglobulin synthesis, the endoplasmic reticulum of MM cells is subjected to elevated basal levels of stress. Consequently, proteasome inhibitors, which exacerbate this stress by inhibiting ubiquitin-proteasome-mediated protein degradation, are an important new class of chemotherapeutic agents being used to combat this disease. However, MM cells still develop resistance to proteasome inhibitors such as carfilzomib. Toward this end, we have established carfilzomib-resistant derivatives of MM cell lines. We found that resistance to carfilzomib was associated with elevated levels of prosurvival autophagy, and Kruppel-like factor 4 ...


Amyotrophic Lateral Sclerosis, The Primary Motor Neuron Disease, Jacob P. Naumann 2015 Cleveland State University

Amyotrophic Lateral Sclerosis, The Primary Motor Neuron Disease, Jacob P. Naumann

The Downtown Review

Amyotrophic lateral sclerosis is a degenerative neurological disease that damages nerve cells in the brain, in particular the neurons that are involved in voluntary muscle movements. Internationally the disorder is also known as Charcot’s disease and motor neuron disease. In the United States, amyotrophic lateral sclerosis is often referred to as Lou Gehrig’s disease, motor neuron disease, and more colloquially ALS. Amyotrophic Lateral Sclerosis is the most prominent of the five motor neuron diseases, distinguishing itself from the others through degeneration of both upper motor neurons (UMN) and lower motor neurons (LMN) respectively. The “Father of neurology” Jean-Marie ...


Novel Advances In Alzheimer's Disease, Jacob P. Naumann 2015 Cleveland State University

Novel Advances In Alzheimer's Disease, Jacob P. Naumann

The Downtown Review

Alzheimer’s disease, the most common form of dementia in adults, is a progressive degenerative neurological disease that affects memory, cognition, and behavior. Dr. Alois Alzheimer discovered and diagnosed the irreversible disease in 1906 after documenting the famous case of Auguste Deter.1 Since the discovery of the disease, numerous advances have made it possible to not only better understand the causal factors, but also to improve the medical diagnosis and preventative measures that healthcare providers can implement. For the first time since 1984, the National Institute on Aging (NIAA) and the Alzheimer’s Association (AA) proposed and published new ...

The Physiological Effects Of A Cross Country Bike Ride On Novice Cyclists, Wade Weatherholt 2015 Western Kentucky University

The Physiological Effects Of A Cross Country Bike Ride On Novice Cyclists, Wade Weatherholt

Honors College Capstone Experience/Thesis Projects

Purpose: The physiological responses and adaptations experienced by novices engaging in cross-country cycling have received little attention in the scientific literature. Such endeavors typically involve a sizeable increase in physical activity for most individuals, but the acute and chronic effects of such an endurance feat are not well understood. Similarly, research shows that experienced cyclists often demonstrate osteoporosis in the spine, linked to many years of training accompanied by little or no weight bearing stress upon the axial skeleton. Greater understanding of these issues is needed, as long distance cycling has increased in popularity in recent years, and exercise professionals ...


Caenorhabditis Elegans Micrornas Of The Let-7 Family Act In Innate Immune Response Circuits And Confer Robust Developmental Timing Against Pathogen Stress, Zhiji Ren, Victor R. Ambros 2015 University of Massachusetts Medical School

Caenorhabditis Elegans Micrornas Of The Let-7 Family Act In Innate Immune Response Circuits And Confer Robust Developmental Timing Against Pathogen Stress, Zhiji Ren, Victor R. Ambros

GSBS Student Publications

Animals maintain their developmental robustness against natural stresses through numerous regulatory mechanisms, including the posttranscriptional regulation of gene expression by microRNAs (miRNAs). Caenorhabditis elegans miRNAs of the let-7 family (let-7-Fam) function semiredundantly to confer robust stage specificity of cell fates in the hypodermal seam cell lineages. Here, we show reciprocal regulatory interactions between let-7-Fam miRNAs and the innate immune response pathway in C. elegans. Upon infection of C. elegans larvae with the opportunistic human pathogen Pseudomonas aeruginosa, the developmental timing defects of certain let-7-Fam miRNA mutants are enhanced. This enhancement is mediated by the p38 MAPK innate immune pathway acting ...


Response Of Endothelial Cells To Quantified Hemodynamic Shear Stress, Hamed Avari 2015 The University of Western Ontario

Response Of Endothelial Cells To Quantified Hemodynamic Shear Stress, Hamed Avari

University of Western Ontario - Electronic Thesis and Dissertation Repository

Cardiovascular diseases (CVDs) are the number one cause of death globally. Arterial endothelial cell (EC) dysfunction plays a key role in many of these CVDs, such as atherosclerosis. Blood flow-induced wall shear stress (WSS), among many other pathophysiological factors, is shown to significantly contribute to EC dysfunction.

The present dissertation is an in vitro investigation of quantified WSS on ECs to quantitatively analyze the EC morphometric parameters, as well as cytoskeletal remodeling.

A hemodynamic facility based on the parallel plate flow chamber (PPFC) concept. The Laser Doppler Velocimetry (LDV) method with a custom set-up was implemented to suit the needs ...

HuMan: A Cat Dissection Tutorial

Human anatomy is a topic that many important scientific studies depend on, such as the study of medicine or the research of cultural gender identities and their respective anatomical characteristics. It is logical to expect those who want to work with and study the human body to have a greater understanding of what makes us what we are. Unfortunately this topic is typically considered difficult to learn as there is a very large amount of material to memorize and even more material to comprehend in order to truly achieve an understanding of the human body ...

Anatomical Variation Of The Inferior Mesenteric Vein’S Drainage Pattern, Mina Zilaie B.S.

Theses and Dissertations

The purpose of this project is to report the variable drainage pattern of the inferior mesenteric vein (IMV) as reported by medical students’ observations recorded on anatomical variation data sheets (n = 192). A meta-analysis on the drainage pattern of the inferior mesenteric vein as described in various anatomy resources was conducted (n = 40). The inferior mesenteric vein was observed to drain into the splenic vein, the superior mesenteric vein, and the junction between the superior mesenteric vein and the splenic vein. Anatomy resources do not commonly report all three drainage sites. It is imperative that all these common drainage sites ...


Src Homology 2 Domain-Containing 5’-Inositol Phosphatase-2 (Ship2) Is An Effector Of Lymphatic Dysfunction, Germaine D. Agollah 2015 The University of Texas Graduate School of Biomedical Sciences at Houston

Src Homology 2 Domain-Containing 5’-Inositol Phosphatase-2 (Ship2) Is An Effector Of Lymphatic Dysfunction, Germaine D. Agollah

UT GSBS Dissertations and Theses (Open Access)

The lymphatic system is essential for the transport of excess fluid, protein, and foreign materials from interstitial tissues to lymph nodes; for immune surveillance, and to maintain fluid homeostasis. Dysregulated lymphatics can be attributed to pathological conditions including tumor metastasis, inflammation, chronic wounds, obesity, blood vascular disorders, and lymphedema. Of these, lymphedema is the most extreme of lymphatic disorders and is represented by a spectrum of symptoms ranging from mild, subtle presentation to severe, disfiguring, overt presentation. Lymphedema is more manageable in the early stages of disease but severely reduces quality of life with progression. Due to lack of molecular ...
