Microencapsulation of Liquid Cyanoacrylate via In situ Polymerization for Self-Healing
Comparison of Acoustic Radiation Force Impulse (ARFI) Imaging and Shear Wave Imaging (SWI) in Evaluation of Myocardial Ablation Lesions
Radiofrequency ablation (RFA) is commonly used to treat cardiac arrhythmias, by generating a series of discrete RFA lesions in the myocardium to isolate arrhythmogenic conduction pathways. The size of each lesion is controlled ...
Direct Differentiation of Mouse Induced Pluripotent Stem Cells into Nucleus Pulposus-Like Cells
The intervertebral discs (IVD) contribute to structural stability of the spinal column, attenuate the impact of compressive loads, and enable a wide spectrum of motions. As a consequence of aging, the majority of the adult ...
Correcting Motion Artifacts in Multi-Shot Diffusion-Weighted EPI Using Iterative Phase Cycling
Diffusion-weighted MRI (DWI) is an essential tool in clinical applications such as detecting ischemic stroke, and in research applications studying neuronal connectivity in the brain. Diffusion-weighted imaging with multi-shot ...
Response of Midbrain Pain Receptors in a Rodent Model of Radiculopathy
<bold>Introduction:</bold> Intervertebral disc herniation may contribute to nerve root compression or inflammatory processes that are associated with radicular pain and motor deficits. Molecular changes at the affected dorsal ...
Characterization of Polyethersulfone (PES) and Polyvinylidene Difluoride (PVDF) Resistive Membranes under In Vitro Staphylococcus aureus Challenge
Bacterial colonization of a medical device has been seen to precede clinical infection as well as adversely affect function of the indwelling device. This is a major cause of implant failure with the most common bacterial ...
Biomechanics of Coupled Motion in the Cervical Spine During Simulated Whiplash in Patients with Pre-existing Cervical or Lumbar Spinal Fusion: A Finite Element Study
It is well understood that loss of motion following spinal fusion increases strain in the adjacent motion segments. However, it is unclear if to date, studies on cervical spine biomechanics can be affected by the role of ...
Network Effects of Deep Brain Stimulation for Parkinson's Disease - A Computational Modeling Study
Electrical stimulation of the sub-cortical regions (basal ganglia) of the brain, also known as deep brain stimulation (DBS), is an effective treatment technique for neurological diseases such as Parkinson's disease and essential ...
Scatter Correction for Dual-source Cone-beam CT Using the Pre-patient Grid
<bold>Purpose</bold>: A variety of cone beam CT (CBCT) systems has been used in the clinic for image guidance in interventional radiology and radiation therapy. Compared with conventional single-source CBCT, dual-source ...
Proposed Method to Evaluate the Impact on Health Outcomes of Capacity Building for Maintenance and Repair of Medical Equipment in Rwanda
It has been shown that training biomedical equipment technicians (BMETs) improves healthcare, but it is unclear if capacity building for repair and maintenance of medical equipment leads to improved patient health outcomes, ...
