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 Western University

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 2014 Himmelfarb Health Sciences Library, The George Washington University

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 ...

Interaction Among Gustation, Olfaction, And Vision In Flavor Identification, Michael J. Lauth 2014 California Polytechnic State University

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 ...

Dreams And Learning, Cody Mebane Gibbons

Symposium

Project Summary: This study is being done to test one aspect of how paying attention to one’s dreams may influence our waking lives. The idea was inspired by research linking the brain processes involved in long-term memory storage to qualities of dreaming, as well as the potential for learning in lucid dreams. It is hypothesized that the more conscious one is of one’s dreams and dream world, the better one will be at learning. In order to test this, the dreaming ability of 300 Cal Poly students will be analyzed via dream questionnaires with the purpose of seeing ...


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 2014 University of Massachusetts Medical School

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 ...


Displacement Across A Fracture Gap With Axial Loading Of Far Cortical Locking Constructs, Peter J. Wagner, Dennis T. Murphy, Kristen L. Billiar, Judith Siegel, John J. Wixted 2014 University of Massachusetts Medical School

Displacement Across A Fracture Gap With Axial Loading Of Far Cortical Locking Constructs, Peter J. Wagner, Dennis T. Murphy, Kristen L. Billiar, Judith Siegel, John J. Wixted

UMass Center for Clinical and Translational Science Research Retreat

Purpose: Far cortical locking has been proposed for reducing stiffness and promoting greater dynamic stability in locked plating constructs. Prior studies have shown reduced stiffness with axial loading of these constructs, leading to a theoretical increase in inter-fragmentary motion and secondary bone healing. The purpose of this study was to examine strain across a fracture gap using far cortical locking constructs in a biomechanical model of distal femoral fractures.

Methods: Fourth generation sawbones were cut transversely along the distal diaphysis and plated with distal femoral buttress plates and cortical locking screws. Far cortical locking (FCL) specimens were predrilled in the ...

Differential Burden Of Musculoskeletal Pain In Blacks And Whites At The Time Of Total Joint Replacement Surgery, Anthony Porter, Leslie R. Harrold, Philip C. Noble, David C. Ayers, Patricia D. Franklin, Jeroan Allison

UMass Center for Clinical and Translational Science Research Retreat

Introduction: The existence of racial disparities in total knee (TKR) and hip (THR) replacement outcomes is well established. The role of musculoskeletal co-morbidities among black and white TKR patients at the time of surgery were investigated in a prospective cohort enrolled in the FORCE-TJR consortium of 131 surgeons in 22 US states. Materials & methods: Descriptive analyses were performed on 3,306 TKR and 2,439 THR patients. Data included sociodemographic factors (age, sex, race), BMI, comorbid conditions using the modified Charlson comorbidity scores, burden of musculoskeletal disease using the Knee/Hip injury and Osteoarthritis Outcome Score (KOOS/HOOS) in both knees and hips, emotional health based on the Short Form 36 (SF-36) Mental Component Score (MCS) and physical function based on the Physical Component Score (SF-36 PCS). Factors associated with pre-operative surgical joint pain and function were examined using multivariate stepwise linear regression models. Results: Compared to Whites, Blacks (143 hips and 201 knees) reported worse surgical joint pain (mean pain: 39.3 vs. 49.2 (hip); 43.4 vs. 53.2 (knee)), poorer surgical joint function (mean function: 38.9 vs. 45.7 (hip); 45.9 vs. 53.4 (knee)), poorer global function (mean PCS: 30.0 vs. 31.6 (hip); 31.3 vs. 33.1 (knee)), and more non-operative joints pain.

Background

Liver metastasis is the most common cause of death in patients with colorectal cancer. Despite extensive research into the biology of cancer progression, the molecular mechanisms that drive colorectal cancer metastasis are not well characterized.

Methods

HT29 LM1, HT29 LM2, HT29 LM3 cell lines were derived from the human colorectal cancer cell line HT29 following multiple rounds of in vivo selection in immunodeficient mice.

Results

CD44 expression, a transmembrane glycoprotein involved in cell-cell and cell-matrix adhesions, and cancer cells adhesion to endothelial cells was increased in all in vivo selected cell lines, with maximum CD44 expression and cancer cells ...


A Comparison Of Angiography Versus Intravascular Ultrasound In The Treatment Of Peripheral Arterial Disease, Michael Pompliano 2014 University of South Carolina

A Comparison Of Angiography Versus Intravascular Ultrasound In The Treatment Of Peripheral Arterial Disease, Michael Pompliano

Senior Theses

Peripheral Arterial Disease is a growing epidemic throughout the United States. It is estimated that 8 to 12 million Americans currently suffer from PAD, a disease of the circulatory system that limits blood flow to your hands and feet. This limited blood flow is due to the narrowing of the arteries that supply blood throughout your body and can disrupt the balance of the nerves and tissues that make up your extremities. If left untreated, it can cause irreparable, life- threatening damage that may result in amputation of the diseased limb. Although the mechanism of PAD is known and well ...

Functionalization And Modification Of Naphthaquinone Analogs As Her2 Kinase Inhibitors, Divya Jyothi Lella 2014 Western Kentucky University

Functionalization And Modification Of Naphthaquinone Analogs As Her2 Kinase Inhibitors, Divya Jyothi Lella

Masters Theses & Specialist Projects

HER2 overexpression in breast cancer tumors predicts lower overall survival. Because of the aggressive nature of HER2 tumors and the association with metastatic disease, the HER2 receptor holds great promise as a therapeutic target in metastatic breast cancer. We are developing small molecule inhibitors that bind to the ATP binding site of the tyrosine kinase domain in order to inhibit tyrosine auto-phosphorylation. This process controls biological pathways that mediate the cell growth. In normal cells this process is highly controlled. We are targeting the modification of the side chain of the hydroxy methyl group of 2-Hydroxy methyl-5,8-dimethoxy-1,4-naphthaquinone. These ...

Anatomy Articles

Cartilage and osteochondral defects pose a significant challenge in orthopedics. Tissue engineering has shown promise as a potential method for the treatment of such defects; however, a long-lasting repair strategy has yet to be realized. This study focuses on the development of a layered construct for osteochondral repair, fabricated through a novel "iterative layering" freeze-drying technique. The process involved repeated steps of layer addition followed by freeze-drying, enabling control over material composition, pore size and substrate stiffness in each region of the construct, while also achieving a seamlessly integrated layer structure. The novel construct developed mimics the inherent gradient structure ...


Structural Alterations To The Axon Initial Segment Following Diffuse Axonal Injury As A Consequence Of Age, William Behl 2014 Virginia Commonwealth University

Structural Alterations To The Axon Initial Segment Following Diffuse Axonal Injury As A Consequence Of Age, William Behl

Theses and Dissertations

An epidemiological shift towards the elderly population has occurred in traumatic brain injury (TBI). Age is believed to be one of the strongest prognostic indicators following TBI. Diffuse axonal injury (DAI), a prevalent feature of TBI, is believed to be the primary cause for much of the morbidity and mortality associated with TBI. The pathobiology associated with DAI is believed to occur in response to the primary injury in a progressive, secondary fashion. Though the injury mechanisms behind DAI have been shown to occur at numerous sites along the axon, recent work suggests that the axon initial segment (AIS) may ...

Bone degenerative diseases are on the increase globally and are often problematic to treat. This has led to a demand to identify supplements that aid bone growth and formation. Aquamin is a natural multi-mineral food supplement, derived from the red algae Lithothamnion species which contains calcium, magnesium and 72 other trace minerals. It has been previously reported to increase bone formation and mineralisation. This study aimed to investigate the 28 day in vitro osteogenic response of Aquamin supplemented with Vitamin D. The osteogenic potential of MC3T3-E1 osteoblast-like cells was analysed in standard osteogenic medium supplemented with Aquamin +/- Vitamin D3, and ...


Assessing The Relationship Between The Blood-Air Partition Coefficient And Fractional Uptake Of Inspired Halothane, Acetone, And Ethanol Vapors In The Airways Of The C57bl/6j Mouse, Joshua Baruch Baldino 2014 University of Connecticut

Assessing The Relationship Between The Blood-Air Partition Coefficient And Fractional Uptake Of Inspired Halothane, Acetone, And Ethanol Vapors In The Airways Of The C57bl/6j Mouse, Joshua Baruch Baldino

Honors Scholar Theses

The following series of studies investigates the elimination and uptake trends of halothane, acetone, and ethanol vapors in the airways of C57BL/6J mice. These vapors were chosen because they span a wide range of solubilities, as indicated by their blood-air partition coefficients, and are not associated with any significant airway metabolism or reactivity with tissue substrates in vivo. Mice were exposed to a homogeneous vapor mixture containing a 1:1:1 ratio of halothane, acetone, and ethanol at relative concentrations of approximately 10 ppm. Exposure studies were performed with mice in two states, conscious and deceased, in order to ...
