Fabrication and Characterization of Three Dimensional Electrospun Cortical Bone Scaffolds
(De Gruyter Open, 2014)Bone is a composite tissue composed of an organic matrix, inorganic mineral matrix and water. Structurally, bone is organized into two distinct types: trabecular (or cancellous) and cortical (or compact) bone. Cortical ... -
A Fast CT Reconstruction Scheme for a General Multi-Core PC
(Hindawi, 2007-07-04)Expensive computational cost is a severe limitation in CT reconstruction for clinical applications that need real-time feedback. A primary example is bolus-chasing computed tomography (CT) angiography (BCA) that we have ... -
Flow Measurements in a Blood-Perfused Collagen Vessel Using X-Ray Micro-Particle Image Velocimetry
(2013-11-18)Blood-perfused tissue models are joining the emerging field of tumor engineering because they provide new avenues for modulation of the tumor microenvironment and preclinical evaluation of the therapeutic potential of new ... -
Fluid shear stress impacts ovarian cancer cell viability, subcellular organization, and promotes genomic instability
(PLOS, 2018-03-22)Ovarian cancer cells are exposed to physical stress in the peritoneal cavity during both tumor growth and dissemination. Ascites build-up in metastatic ovarian cancer further increases the exposure to fluid shear stress. ... -
Folate Conjugated Cellulose Nanocrystals Potentiate Irreversible Electroporation-induced Cytotoxicity for the Selective Treatment of Cancer Cells
(Adenine Press, 2014-04-16)Cellulose nanocrystals are rod-shaped, crystalline nanoparticles that have shown prom- ise in a number of industrial applications for their unique chemical and physical properties. However, investigations of their abilities ... -
Folic Acid-Conjugated Cellulose Nanocrystals Show High Folate-Receptor Binding Affinity and Uptake by KB and Breast Cancer Cells
(American Chemical Society, 2018-10-24)The study evaluates cellulose nanocrystals (CNCs) as nanocarriers for targeted, intracellular delivery of molecular agents. CNCs were labeled with fluorescein-5′-isothiocyanate as an imaging agent and conjugated to folic ... -
Frame-Based Stereotactic Biopsy of Canine Brain Masses: Technique and Clinical Results in 26 Cases
(2015)This report describes the methodology, diagnostic yield, and adverse events (AE) associated with frame-based stereotactic brain biopsies (FBSB) obtained from 26 dogs with solitary forebrain lesions. Medical records were ... -
A General Formula for Fan-Beam Lambda Tomography

A General Local Reconstruction Approach Based on a Truncated Hilbert Transform
(Hindawi, 2007-06-17)Exact image reconstruction from limited projection data has been a central topic in the computed tomography (CT) field. In this paper, we present a general region-of-interest/volume-of-interest (ROI/VOI) reconstruction ... -
A General Total Variation Minimization Theorem for Compressed Sensing Based Interior Tomography
(Hindawi, 2009-11-17)Recently, in the compressed sensing framework we found that a two-dimensional interior region-of-interest (ROI) can be exactly reconstructed via the total variation minimization if the ROI is piecewise constant (Yu and ... -
GPU-Based Acceleration for Interior Tomography
(IEEE, 2014)The compressive sensing (CS) theory shows that real signals can be exactly recovered from very few samplings. Inspired by the CS theory, the interior problem in computed tomography is proved uniquely solvable by minimizing ... -
Heat transfer model to characterize the focal cooling necessary to suppress spontaneous epileptiform activity
(SPIE, 2005-04-14)Epilepsy is characterized by paroxysmal transient disturbances of the electrical activity of the brain. Symptoms are manifested as impairment of motor, sensory, or psychic function with or without loss of consciousness or ... -
High-frequency irreversible electroporation (H-FIRE) for non-thermal ablation without muscle contraction
(2011-11-21)Background Therapeutic irreversible electroporation (IRE) is an emerging technology for the non-thermal ablation of tumors. The technique involves delivering a series of unipolar electric pulses to permanently destabilize ... -
High-Frequency Irreversible Electroporation for Intracranial Meningioma: A Feasibility Study in a Spontaneous Canine Tumor Model
(Sage, 2018)High-frequency irreversible electroporation is a nonthermal method of tissue ablation that uses bursts of 0.5- to 2.0-microsecond bipolar electric pulses to permeabilize cell membranes and induce cell death. High-frequency ... -
Hybrid detector modules and dynamic thresholding for spectral CT
(United States Patent and Trademark Office, 2018-01-09)A system and method that comprises an X-ray source configured to emit an X-ray beam; an object positioned to receive the X-ray beam; a detector configured to receive an attenuated beam of the X-rays through the object for ... -
Image Reconstruction For Bioluminescence Tomography From Partial Measurement
(Optical Society of America, 2007-09-01)The bioluminescence tomography is a novel molecular imaging technology for small animal studies. Known reconstruction methods require the completely measured data on the external surface, although only partially measured ... -
Improved Local and Systemic Anti-Tumor Efficacy for Irreversible Electroporation in Immunocompetent versus Immunodeficient Mice
(PLOS, 2013-05-24)Irreversible electroporation (IRE) is a non-thermal focal ablation technique that uses a series of brief but intense electric pulses delivered into a targeted region of tissue, killing the cells by irrecoverably disrupting ... -
Improving the Accuracy of the Diffusion Model in Highly Absorbing Media
(Hindawi, 2007-08-29)The diffusion approximation of the Boltzmann transport equation is most commonly used for describing the photon propagation in turbid media. It produces satisfactory results in weakly absorbing and highly scattering media, ... -
In Cocaine Dependence, Neural Prediction Errors During Loss Avoidance Are Increased With Cocaine Deprivation and Predict Drug Use
(Elsevier, 2018-08-03)Background: In substance-dependent individuals, drug deprivation and drug use trigger divergent behavioral responses to environmental cues. These divergent responses are consonant with data showing that short- and long-term ... -
In Situ Bioprinting of Autologous Skin Cells Accelerates Wound Healing of Extensive Excisional Full-Thickness Wounds
(Springer Nature, 2019-02-21)The early treatment and rapid closure of acute or chronic wounds is essential for normal healing and prevention of hypertrophic scarring. The use of split thickness autografts is often limited by the availability of a ...
