Association Between Body Surface Area And Outcomes After Percutaneous Coronary Intervention, Kambiz Shetabi, Tonga Nfor, Fengyi Shen, Anjan Gupta, Tanvir Bajwa, Suhail Allaqaband

Journal of Patient-Centered Research and Reviews

Purpose

Obesity is a well-known risk factor for adverse cardiovascular events, but some studies suggest higher body mass index (BMI) is associated with better outcomes after ST-segment elevation myocardial infarction (STEMI). We sought to determine the effect of body surface area (BSA) on adverse events after primary percutaneous coronary intervention (PCI) for STEMI and how this relates to the reported obesity paradox theory.

Methods

We analyzed a prospective registry of patients with STEMI who underwent primary PCI at a tertiary care hospital from 2003 to 2009. Post-PCI complications and 1-year all-cause mortality were compared across BSA quartiles. Relationship with 1-year ...

The Effect Of Chronic Sleep Deprivation On Tumor Necrosis Factor Alpha And Bone Health In Peri-Menopausal Rats, Megan Robertson, Derek Booth, Erin Wainwright, Cody Arbuckle, Frank Frisch

Undergraduate Student Research Day Abstracts and Posters

Post-menopausal osteoporosis is a common syndrome in the United States. The cessation of estrogen signaling coupled with the production of pro-inflammatory cytokines from sleep deprivation leads to an even greater risk of post-menopausal osteoporosis by creating an imbalance between osteoblasts and osteoclasts. With estrogen no longer present to regulate the concentration of osteoclasts and pro-inflammatory cytokines increasing production of osteoclasts, bone is degraded at a faster rate than it is formed. One of the most common treatments for osteoporosis is Zolendronate (a nitrogenous bisphosphonate), which decreases the number of osteoclasts in bone. This preliminary study looked at the effects on ...

Structure-Based Network Analysis Of Activation Mechanisms In The Erbb Family Of Receptor Tyrosine Kinases: The Regulatory Spine Residues Are Global Mediators Of Structural Stability And Allosteric Interactions, Kevin A. James, Gennady M. Verkhivker

Mathematics, Physics, and Computer Science Faculty Articles and Research

The ErbB protein tyrosine kinases are among the most important cell signaling families and mutation-induced modulation of their activity is associated with diverse functions in biological networks and human disease. We have combined molecular dynamics simulations of the ErbB kinases with the protein structure network modeling to characterize the reorganization of the residue interaction networks during conformational equilibrium changes in the normal and oncogenic forms. Structural stability and network analyses have identified local communities integrated around high centrality sites that correspond to the regulatory spine residues. This analysis has provided a quantitative insight to the mechanism of mutation-induced ‘‘superacceptor’’ activity ...

Regulation Of Peripheral Molecular Clocks In Mammalian Tissues And In Vitro Skeletal Muscle Activation Of Amp-Activated Protein Kinase Via Aicar, Alex C. Lupolt '15, Daniel P. Moorhead '16, Josef Brandauer

Student Publications

Most organisms possess a common molecular machinery that governs cellular and tissue circadian rhythmicity through a roughly 24-hour transcription-translation feedback loop. It is estimated that up to 15 percent of human genes are influenced by the core clock machinery. It is likely, however, that the metabolic networks affected by the molecular clock differ according to body tissue.

Recent evidence suggests that peripheral molecular clocks are governed to a greater extent by energy availability than by light and dark cycles. AMP-activated protein kinase (AMPK) acts as a cellular fuel gauge within the cell and is activated in response to exercise and ...


What Are The Best Skeletal Indicators Of Handedness?, Margret B. White, Anne Su 2014 Cleveland State University

What Are The Best Skeletal Indicators Of Handedness?, Margret B. White, Anne Su

Undergraduate Research Posters 2014

Previous research indicates that there are asymmetries in limb bone structure and dimensions. It is hypothesized that these asymmetries are the result of hand preference, or repeated unilateral mechanical loading. The aim of this study was to first identify the best skeletal indicators of handedness by means of a comprehensive literature search. Based on the previous findings of other researchers, we examined non-pathological male individuals (N=19, aged 20-35) from the Hamann-Todd Skeletal Collection at the Cleveland Museum of Natural History for asymmetry of paired second metacarpals, by measuring the difference between right and left diameters at mid-shaft. We also ...

Enamel Matrix Derivative Has No Effect On The Chondrogenic Differentiation Of Mesenchymal Stem Cells, Lisanne C. Groeneveldt, Callie Knuth, Janneke Witte-Bourna, Fergal O'Brien, Eppo B. Wolvius, Eric Farrell

Anatomy Articles

Background: Treatment of large bone defects due to trauma, tumor resection, or congenital abnormalities is challenging. Bone tissue engineering using mesenchymal stem cells (MSCs) represents a promising treatment option. However, the quantity and quality of engineered bone tissue are not sufficient to fill large bone defects. The aim of this study was to determine if the addition of enamel matrix derivative (EMD) improves in vitro chondrogenic priming of MSCs to ultimately improve in vivo MSC mediated endochondral bone formation.

Methods: MSCs were chondrogenically differentiated in 2.0 × 105 cell pellets in medium supplemented with TGFβ3 in the absence or presence ...


Surgical Approach In Total Hip Arthroplasty: Patient Outcomes And Impact On Costs, Stephen M. Petis 2014 The University of Western Ontario

Surgical Approach In Total Hip Arthroplasty: Patient Outcomes And Impact On Costs, Stephen M. Petis

University of Western Ontario - Electronic Thesis and Dissertation Repository

Total hip arthroplasty is often renowned as one of the most important surgical advances of the past century. Orthopaedic surgeons must choose a surgical approach to gain access to the hip joint in order to perform the reconstruction. There is debate in the literature as to which surgical approach optimizes patient outcomes, minimizes complications, and reduces costs to hospitals as a high volume procedure.

In the current studies, patient reported outcomes were compared at short-term follow-up using a prospective study design across the anterior, posterior, and lateral approach. A micro-costing method was used to acquire costs related to each procedure ...


Vascular Architecture Of The Liver In Shr And Wky Rats, Charalette Mathwig, Kenneth Willaert 2014 Minnesota State University, Mankato

Vascular Architecture Of The Liver In Shr And Wky Rats, Charalette Mathwig, Kenneth Willaert

Journal of Undergraduate Research at Minnesota State University, Mankato

The liver is a highly complex vascular organ containing an intricate network of arteries, arterioles, portal veins, veins, venules, and capillaries. This complex network could change in situations related to vascular disease such as hypertension. We examined the vasculature in rat livers by scanning electron microscopy. The tissue was prepared by perfusing either Mercox resin or polyurethane resin into the vasculature. Once the resin polymerized, each liver was placed in concentrated potassium hydroxide to corrode the tissue from the vascular casts. The casts were critical point dried, sputter coated with gold-palladium, and viewed by scanning electron microscopy. Examination of the ...

Simultaneous Measurement Of Smoothened Entry Into And Exit From The Primary Cilium, Jynho Kim, Elaine Y.C. Hsia, James Kim, Navdar Sever, Philip A. Beachy, Xiaoyan Zheng

Anatomy and Regenerative Biology Faculty Publications

Ciliary accumulation of signaling proteins must result from a rate of ciliary entry that exceeds ciliary exit, but approaches for distinguishing ciliary entry vs. exit are lacking. Using a photoconvertible fluorescent protein tag, we establish an assay that allows a separate but simultaneous examination of ciliary entry and exit of the Hedgehog signaling protein Smoothened in individual cells. We show that KAAD-cyclopamine selectively blocks entry, whereas ciliobrevin interferes initially with exit and eventually with both entry and exit of ciliary Smoothened. Our study provides an approach to understanding regulation of ciliary entry vs. exit of Hedgehog signaling components as well ...

Pharmacy Faculty Articles and Research

A Disintegrin And Metalloproteinase with ThromboSpondin motifs16 (ADAMTS-16) is a member of a family of metalloproteinases. Using a novel zinc-finger nuclease based gene-edited rat model harboring a targeted mutation of the Adamts16 locus, we previously reported this gene to be linked to blood pressure regulation. Here we document our observation with this model that Adamts16 is essential for normal development of the testis. Absence of Adamts16 in the homozygous Adamts16(mutant) males resulted in cryptorchidism and male sterility. Heterozygous Adamts16(mutant) males were normal, indicating that this is a recessive trait. Testes of homozygous Adamts16(mutant) males were significantly smaller ...

Interaction Among Gustation, Olfaction, And Vision In Flavor Identification, Michael J. Lauth

Symposium

Even though the senses of taste, smell, and sight are distinct, there is a significant overlap among them in our perceptions of objects that helps us understand and differentiate the world. Everyone has experienced, when his or her nose gets congested, that his or her sense of taste changes as well. Many individuals do not equally understand the top-down processing with taste when someone sees objects they are about to eat. In the replicated study by our principle investigator, a random convenience sample of young adults (n=162) were recruited and tested to determine if they could taste four Jelly ...

The small intestine generally transports dietary fats to circulation in triglyceride (TG)-rich lipoproteins. The two main intestinal lipoproteins are chylomicron (CM) and very low-density lipoprotein (VLDL). Unfortunately, studies on the CM biogenesis and intestinal transport of dietary fats have been hampered by the lack of an adequate in vitro model. In this study, we investigated the possible factors that might increase the efficiency of CM production by Caco-2 cells. We utilized sequential NaCl gradient ultracentrifugation to isolate the CMs that were secreted by the Caco-2 cells. To confirm the successful isolation of the CMs, we performed Fat Red 7B ...


Endothelial And Smooth Muscle-Dependent Vascular Reactivity In Immature Arterialized Collateral Capillaries, Caitlin Koeroghlian 2014 California Polytechnic State University - San Luis Obispo

Endothelial And Smooth Muscle-Dependent Vascular Reactivity In Immature Arterialized Collateral Capillaries, Caitlin Koeroghlian

Biomedical Eng/General Eng.

Peripheral arterial occlusive disease (PAOD) occurs due to the build up of atherosclerotic plaque and reduces blood flow to cause chronic ischemia. Patients with PAOD may experience intermittent claudication, or the pain in limb skeletal muscles due to a decease in blood flow. Collateral arteries can act as a natural bypass and improve blood flow to hypoxic tissue by creating an alternate route for blood to flow, but not all patients with PAOD have pre-existing collateral networks. Animal studies indicate that tissues without pre-existing collateral networks can form de novo collaterals from capillaries following occlusion of a feed artery. Unfortunately ...

Vancomycin-Bearing Synthetic Bone Graft Delivers Rhbmp-2 And Promotes Healing Of Critical Rat Femoral Segmental Defects, Jordan D. Skelly, Jeffrey Lange, Tera M. Filion Potts, Xinning Li, David C. Ayers, Jie Song

UMass Center for Clinical and Translational Science Research Retreat

For graft-assisted repair of large volumetric bone loss resulting from traumatic orthopedic injuries, strategies that simultaneously promote osteointegration/graft healing and mitigate risks for infections are highly desired. Previously, we developed a poly(2-hydroxyethyl methacrylate)-nanocrystalline hydroxyapatite (pHEMA-nHA) composite as a synthetic bone graft. The composite, when loaded with a single dose of 400-ng rhBMP-2/7 and press-fit into a 5-mm rat femoral segmental defect, led to bony callus fully bridging over the defect and substantial restoration of the torsional rigidity by 12 weeks. More recently, we showed that 4.8 wt% vancomycin can be encapsulated within the composite without ...
