Phantom Limb Pain (PLP) is commonly suffered by people with amputations and even though it has been studied for centuries, it remains a mysterious object of debate among researchers. For one thing, despite the vast number of proposed PLP treatments, no therapy has so far proved …

Background: The study of impact biomechanics in contact sports has improved our current understanding of concussion mechanisms and the cumulative effects of subconcussive impacts on brain health. Impact exposure is often described by the total insults an athlete sustains or peak…
OBJETIVO:El objetivo principal fue evaluar si existen cambios vasculares, en el grosor coroideo o en la densidad vascular macular, en pacientes con esclerosis múltiple (EM) respecto a controles sanos. Los objetivos secundarios fueron: determinar si existen diferencias vasculares…
Women who are medically underserved may be less likely to obtain provider-based cervical cancer screening because of structural and intrapersonal barriers. Self-collection for human papillomavirus (HPV) testing, a method for women to collect their own sample through a vaginal sw…
Error processing is a facet of cognitive control allowing for the flexible modification of behavior to optimize future outcomes. Models of addiction propose that executive deficits underlie the dysregulation of self-control resulting in the inability to refrain from excessive al…
Concomitant chemoradiation therapy based on platinum chemotherapeutic drugs (Pt-drugs) is a common treatment modality for several types of cancers and has dramatically improved patient survival. The radiosensitization capacity of Pt-drugs results essentially from their binding t…
The main advantage of Proton beam therapy (PBT) over conventional radiotherapy (RT) is the more precise geometrical shape of the energy deposition inside the patient. The Bragg peak at the end of the proton range allows delivery of accurate dose in a deep seated cancer, that als…
Objective. To determine the risk of new ischemic events, demonstrated by magnetic resonance imaging (MRI), in patients undergoing endovascular procedures for cerebrovascular diseases. Methods. I searched in MEDLINE, EMBASE, Current Contents, and Cochrane CENTRAL; expert files, a…
We developed a novel large-stroke deformable mirror for focus control and spherical aberration correction. The mirrors fabricated using MEMS technology provide full range (150-200 μm in tissue) of focus scanning at high numerical aperture (N.A.=0.5-0.7) for confocal microscopy a…
Tissue ablation with minimally invasive surgery is important for treatment of many diseases and has an increasing role in treatment of solid neoplasms. A variety of biophysical and biochemical processes are used for this purpose. They include thermal ablation with heating, cooli…
Magnetic resonance imaging is often used as a source for reconstructing vascular anatomy for the purpose of computational fluid dynamics (CFD) analysis. We recently observed large discrepancies in such "image-based" CFD models of the normal common carotid artery (CCA) derived fr…
Sparse tomography is an efficient technique which saves time as well as minimizes cost. However, due to few angular data it implies the image reconstruction problem as ill-posed. In the ill posed problem, even with exact data constraints, the inversion cannot be uniquely perform…
Resting-state functional magnetic resonance imaging (fMRI) has increasingly gained attention since its introduction fifteen years ago. Its simple data collection procedure makes it a potentially useful clinical tool to investigate reorganization or adaptation of the brain's func…
As liver cancer incidence rates continue to rise and associated death rates follow a twenty-year trend, increasing by three percent each year, targeted radiation therapy provides a method to combat cancer progression in cases where liver resection or transplant is not possible. …
Machine learning with deep neural networks has demonstrated high performance for high dimensionality prediction tasks across multiple domains with sufficient sample data. Cardiovascular disease is a pertinent public health issue that has the potential to be better understood and…
Digital tomosynthesis is a novel three-dimensional imaging technology that utilizes limited number of X-ray projection images to improve the diagnosis and detection of lesions. In recent years, tomosynthesis has been used in a variety of clinical applications such as dental imag…
Traditional 3D computer graphics focus on rendering the exterior of objects. Volume rendering is a technique used to visualize information corresponding to the interior of an object, commonly used in medical imaging and other fields. Visualization of such data may be accomplishe…
Os sinais clínicos com origem abdominal em cães e gatos são dos estímulos iatrotrópicos verificados de forma mais frequente na clínica de cães e gatos, sendo a imagiologia um importante contributo na avaliação e na determinação do sistema originário do quadro clínico. Este estud…
