Lead Burden As A Factor For Higher Complication Rate In Patients With Implantable Cardiac Devices, Christopher Kolibash, Naoyo Mori, Jasbir Sra, Masood Akhtar, M. Eyman Mortada

Mohammad Mortada, MD, FACC, FHRS

Purpose Lead revisions have increased over the last decade. Patients who do not undergo lead extraction face an increased lead burden. Consequences of increased lead burden have not been fully defined. We sought to characterize the complication rate and outcomes in patients with sterile redundant leads. Methods We retrospectively reviewed 242 consecutive patients [mean age 74 ± 12 years; 66.9% male] who underwent lead revision that resulted in an abandoned lead from January 2005 to June 2010. Patients were placed in a cohort based on number of leads after last recorded procedure (Group A: ≤2 [n=58]; Group B: 3-4 ...

Il-15 Activates The Jak3/Stat3 Signaling Pathway To Mediate Glucose Uptake In Skeletal Muscle Cells, James E. Krolopp, Shantaé M. Thornton, Marcia J. Abbott

Health Sciences and Kinesiology Faculty Articles

Myokines are specialized cytokines that are secreted from skeletal muscle (SKM) in response to metabolic stimuli, such as exercise. Interleukin-15 (IL-15) is a myokine with potential to reduce obesity and increase lean mass through induction of metabolic processes. It has been previously shown that IL-15 acts to increase glucose uptake in SKM cells. However, the downstream signals orchestrating the link between IL-15 signaling and glucose uptake have not been fully explored. Here we employed the mouse SKM C2C12 cell line to examine potential downstream targets of IL-15-induced alterations in glucose uptake. Following differentiation, C2C12 cells were treated overnight with 100 ...


Emg Readings In Similar Body Weight And Cable Resistance Exercise, Shane R. O'Donnell 2016 Loyola Marymount University and Loyola Law School

Emg Readings In Similar Body Weight And Cable Resistance Exercise, Shane R. O'Donnell

Research & Exhibition

Abstract: The field of exercise training has infinite possibilities by different modes of exercise, from a variety of handle types to the type of weight being moved. However, all of these modes strive towards the overall goal of muscle mass increase while maintaining joint longevity. Studies have been conducted to contrast at the varying types of equipment used and the equipment’s effect on muscle contraction and growth. Very little research has been done looking at the type of weight being moved and the resultant electrical impulses sent to the muscle fibers to elicit a contraction. This study attempts to ...


The Benefits And Limitations Of Animal Models For Translational Research In Cartilage Repair., Conor J. Moran, Ashwanth Ramesh, Pieter AJ Brama, John M. O'Byrne, Fergal J. O'Brien, Tanya J. Levingstone 2016 Royal College of Surgeons in Ireland

The Benefits And Limitations Of Animal Models For Translational Research In Cartilage Repair., Conor J. Moran, Ashwanth Ramesh, Pieter Aj Brama, John M. O'Byrne, Fergal J. O'Brien, Tanya J. Levingstone

Anatomy Articles

Much research is currently ongoing into new therapies for cartilage defect repair with new biomaterials frequently appearing which purport to have significant regenerative capacity. These biomaterials may be classified as medical devices, and as such must undergo rigorous testing before they are implanted in humans. A large part of this testing involves in vitro trials and biomechanical testing. However, in order to bridge the gap between the lab and the clinic, in vivo preclinical trials are required, and usually demanded by regulatory approval bodies. This review examines the in vivo models in current use for cartilage defect repair testing and ...

The purpose of this multicenter, prospective, randomized, placebo-controlled study was to evaluate and compare the efficacy of two cognitive rehabilitation interventions (Memory and Attention Adaptation Training (MAAT) and Attention Builders Training (ABT)), with and without pharmacologic enhancement (i.e., with methylphenidate (MPH) or placebo), for treating persistent cognitive problems after traumatic brain injury (TBI). Adults with a history of TBI at least four months prior to study enrollment with either objective cognitive deficits or subjective cognitive complaints were randomized to receive MPH or placebo and MAAT or ABT, yielding four treatment combinations: MAAT/MPH (N=17), ABT/MPH (N=19 ...


Spatial Organization Of Northern Flying Squirrels, Glaucomys Sabrinus: Territoriality In Females?, Jaya R. Smith, Dirk H. Van Vuren, Douglas A. Kelt, Michael L. Johnson 2016 University of California, Davis

Spatial Organization Of Northern Flying Squirrels, Glaucomys Sabrinus: Territoriality In Females?, Jaya R. Smith, Dirk H. Van Vuren, Douglas A. Kelt, Michael L. Johnson

Michael Johnson

We determined home-range overlap among northern flying squirrels (Glaucomys sabrinus) to assess their spatial organization. We found extensive home-range overlap among females, and though this overlap could reflect social behavior, we found no evidence of attraction among females, with only one instance of den-sharing. Instead, our results suggest that females share foraging areas but may be territorial in portions of the home range, especially around den trees and during young-rearing. Home-range overlap could also result from the extrinsic effect of forest fragmentation due to timber harvest, which might impede dispersal and force squirrels to cluster on remaining fragments of suitable ...


Functional Alterations Of Ion Channels From Cardiac Fibroblasts In Heart Diseases, Gracious R. Ross, Arshad Jahangir 2016 Sheikh Khalifa bin Hamad Al Thani Center for Integrative Research on Cardiovascular Aging, Aurora Research Institute, Aurora Health Care

Functional Alterations Of Ion Channels From Cardiac Fibroblasts In Heart Diseases, Gracious R. Ross, Arshad Jahangir

Journal of Patient-Centered Research and Reviews

In an aged population, cardiovascular disease is the leading cause of fatality and morbidity. Age-related fibrotic remodeling of the heart contributes to progressive myocardial dysfunction. Cardiac fibroblasts (CF), responsible for the maintenance of extracellular matrix and fibrosis process, play an important role in cardiac health and disease. CFs influence myocardial function by their chemical, electrical and mechanical interactions with cardiomyocytes through extracellular matrix deposition or secretion of cytokines and growth factors. These, in turn, are modulated by ion channels, macromolecular pores in the plasma membrane that allow selective ionic fluxes of major ions like K+, Ca2+, Na+ or Cl ...

Can Bedside Ultrasound Inferior Vena Cava Measurements Accurately Diagnose Congestive Heart Failure In The Emergency Department? A Clin-Iq, Miranda Gaskamp, Mark Blubaugh, Laine H. Mccarthy, Dewey C. Scheid

Journal of Patient-Centered Research and Reviews

Congestive heart failure (CHF) is a major cause of morbidity and mortality. Early diagnosis of CHF in patients presenting to the emergency department with undifferentiated dyspnea would allow clinicians to begin appropriate treatment more promptly. Current guidelines recommend B-type natriuretic peptide (BNP) levels for more accurate diagnosis of CHF in dyspneic patients. Although BNP levels are relatively inexpensive, the test is not usually performed at bedside and results may take up to an hour or more. BNP also may have a “gray zone” in which the values can neither confirm nor rule out CHF. BNP has a reported sensitivity of ...

Journal of Patient-Centered Research and Reviews

Purpose

Excessive fibrosis has been suggested to result from persistence of fibroblasts in injured tissue due to impaired apoptosis, but signaling pathways are not fully defined.

Methods

Suppression of apoptotic cell death following transforming growth factor-β1 (TGF-β1) exposure was studied using the culture of NIH/3T3 mouse embryonic fibroblasts. Caspase-3 activity, propidium iodide staining and annexin V binding induced by Fas-ligand (FasL) in NIH/3T3 fibroblasts in the absence and presence of TGF-β1 was determined, and relative contribution of signaling through Smad2/3 and noncanonical Erk1/2 and Akt pathways was dissected by assessing phosphorylation status of these kinases and ...

Pharmacy Faculty Articles and Research

Although primary cilia have been shown to play crucial roles in the development of embryonic mouse heart, their presence and function in adult mouse heart remains controversial. In this study, the presence of primary cilia in adult mouse heart was investigated. The presence of primary cilia was initially demonstrated in the surface of cardiac cells of mouse hearts from both young and adult mice by immunostaining with acetylated α-tubulin, a ciliary structural marker. The presence of cardiac primary cilia in 1-, 3-, 6- and 12-month old mice was further confirmed by staining heart tissues with an antibody against pericentrin, a ...

Get Up, Stand Up: A Brief History Of Sedentarism And Why Movement Is Good Medicine, Tony Federico

Tony Federico

Chairs first emerged as a way for high-status individuals to designate their social standing, and their use was almost exclusively the domain of the affluent class until the Industrial Revolution made affordable, mass-produced seating possible. Prior to this point, the vast majority of people sat on improvised objects such as beds, tree stumps, or benches, or simply squatted on their haunches. Social aspirations, continued technological innovations (e.g. the automobile), and a shift towards sedentary work drove the adoption of the chair until its use became ubiquitous at home, at work, at school, and at play (e.g. computer and ...

Frozen Brain Atlas, Natalie Andrea Builes, Dominick Joseph Casciato, Samantha Taylor Bergoine, Robert Speth

Frozen Brain Atlas

The Frozen Brain Atlas provides students, educators, and scientists with a tool to further explore the architecture of the brain. Current brain atlases allow users to navigate sectioned brain tissue using histological staining; however, they fail to capture naturally visible structures post sectioning. Through immediate post sectioning image collection, the natural contrast of the brain reveals unique structural details that are rarely seen by traditional staining procedures. By utilizing indexing and interactive labeling, the Nova Southeastern University Frozen Brain Atlas will allow identification of brain regions when used as a correlative tool for modalities including receptor autoradiography, immunofluorescence, and other ...
