Preosteoblast Behavior On A Synthetic Calcium Phosphate Scaffold Coated With Cell Derived Matrix, 2010 University of Tennessee Health Science Center
Preosteoblast Behavior On A Synthetic Calcium Phosphate Scaffold Coated With Cell Derived Matrix, Daniel A. Young
Theses and Dissertations (ETD)
Bone grafts are commonly used for the treatment of large bone defects. Biodegradable, synthetic bone grafts combined with cells and growth factors as a tissue engineered construct can provide benefits over the common autografts and allografts currently used. Calcium phosphate (CaP) materials offer high biocompatibility and chemical similarity to natural bone tissue. Biodegradable beta-tricalcium phosphate (β-TCP) scaffolds with an interconnected porous network have been created to promote tissue ingrowth and regeneration in vitro and in vivo. Extracellular matrix (ECM) coated on titanium and polymer scaffolds has been shown to improve cell response to those material surfaces. Here, we attempted to ...
Ion Selective Electrodes (Ises) And Interferences – A Review, 2010 Bond University
Ion Selective Electrodes (Ises) And Interferences – A Review, Goce Dimeski, Tony Badrick, Andrew St John
Ion Selective Electrodes (ISEs) are used to measure some of the most critical analytes on clinical laboratory and point-of-care analysers. These analytes which include Na(+), K(+), Cl(-), Ca(2+), Mg(2+) and Li(+) are used for rapid patient care decisions. Although the electrodes are very selective, they are not free of interferences. It is important for laboratories to have an understanding of the type and extent of interferences in order to avoid incorrect clinical decisions and treatment.
Enhancing Student Usability Of The Osmette, 2010 California Polytechnic State University, San Luis Obispo
Enhancing Student Usability Of The Osmette, Mitchell Foutz
Precision Systems' Micro-Osmette located in the St. Jude Lab at Cal Poly SLO is a freezing-point depression osmometer capable of measuring the osmolality, the concentration of hydrated species in osmoles per-kilogram of water, with unrivaled speed and accuracy. The Osmette could be used extensively by students in a wide variety of applications if students are able to become acquainted with the device in an accelerated manner. The amount of time required to safely and effectively operate the micro-Osmette using the operator's manual provided with the device is prohibitive of widespread use by students. Revisions and improvements to the existing ...

Biomedical Imaging and Biosignal Analysis Laboratory
The present invention provides compounds, methods and systems for sequencing nucleic acid using single molecule detection. Using labeled NPs that exhibit charge-switching behavior, single-molecule DNA sequencing in a microchannel sorting system is realized. In operation, sequencing products are detected enabling real-time sequencing as successive detectable moieties flow through a detection channel. By electrically sorting charged molecules, the cleaved product molecules are detected in isolation Without interference from unincorporated NPs and Without illuminating the polymerase-DNA complex.
Segmentation Of Thermographic Images Of Hands Using A Genetic Algorithm, 2010 Portland State University
Segmentation Of Thermographic Images Of Hands Using A Genetic Algorithm, Payel Ghosh, Judith Gold, Melanie Mitchell
Computer Science Faculty Publications and Presentations
This paper presents a new technique for segmenting thermographic images using a genetic algorithm (GA). The individuals of the GA also known as chromosomes consist of a sequence of parameters of a level set function. Each chromosome represents a unique segmenting contour. An initial population of segmenting contours is generated based on the learned variation of the level set parameters from training images. Each segmenting contour (an individual) is evaluated for its fitness based on the texture of the region it encloses. The fittest individuals are allowed to propagate to future generations of the GA run using selection, crossover and ...
Markers Of Marijuana Use Outcomes Within Adolescent Substance Abuse Group Treatment, 2010 Montclair State University
Markers Of Marijuana Use Outcomes Within Adolescent Substance Abuse Group Treatment, Paul Amrhein, Brett Engle, Mark Macgowan, Eric Wagner
Department of Psychology Faculty Scholarship and Creative Works
Objectives: Despite their popularity, little is known about what distinguishes effective from ineffective or even iatrogenic adolescent group interventions. Methods: Audio recordings and transcripts from 19, 8—10 session, school-based treatment groups comprised of 108, substance abusing 10- to 19-year olds were analyzed. Group leader empathy was measured globally, while two new constructs, group commitment, and peer response, were measured using discourse analysis. All variables were measured at the group level. Results: Associations among these process variables were tested and supported, as were the hypothesized associations between both group member language constructs and marijuana use outcomes. Conclusions: These findings were ...
A Bland–Altman Comparison Of The Lead Care® System And Inductively Coupled Plasma Mass Spectrometry For Detecting Low-Level Lead In Child Whole Blood Samples, Christina Sobin, Tanner Schaub, Natali Parisi, Eva De La Riva
Christina Sobin, Ph.D.
Chronic childhood lead exposure, yielding blood lead levels consistently below 10 μg/dL, remains a major public health concern. Low neurotoxic effect thresholds have not yet been established. Progress requires accurate, efficient, and cost-effective methods for testing large numbers of children. The LeadCare® System (LCS) may provide one ready option. The comparability of this system to the “gold standard” method of inductively coupled plasma mass spectrometry (ICP-MS) for the purpose of detecting blood lead levels below 10 μg/dL has not yet been examined. Paired blood samples from 177 children ages 5.2–12.8 years were tested with LCS ...
Electromyographic Analysis Of Trunk Muscle Activation During A Throwing Pattern Following Rotator Cuff Mobilization, 2010 Claremont McKenna College
Electromyographic Analysis Of Trunk Muscle Activation During A Throwing Pattern Following Rotator Cuff Mobilization, Aubrey L. Doede
CMC Senior Theses
Correct muscular activation of the body segments during an overhand throw is achieved when movement originates in the larger and more proximal legs and trunk and moves sequentially to the smaller, distal segments of the shoulder and arm. This sequence permits angular velocity to transfer progressively through the throw as part of an open kinetic chain. The athlete can summate angular velocity and segmental forces only if he is able to create a separation between the body segments during the movement pattern, and this separation is thus essential to effective segmental sequencing for activation of the trunk muscles to occur ...
