-caprolactone) (PLA-PCL) could be used as marker clip material. After evaluating different polymer rates performance, metallic nanoparticles (NPs) were included to enhance the stability of the best copolymer and a marker clip prototype was proposed. Characterization of nanoparticles was made by dynamic light scattering (DLS), X-ray diffraction (XRD...
the cohort included 27 patients with stage 1, 66 with stage 2, 20 with stage 3, and nine with stage 4 fibrosis. All four biomarkers distinguished stage 3 and stage 2 fibrosis. ROC curves revealed that all four fibrosis biomarkers presented AUC values greater than 0.8. Each of the four biomarkers in stage 2 was significantly different between the ac...

Chondrosarcoma is one of the most frequent malignant bone tumors. We included in the initial study population 110 patients with pelvis biopsies and the histopathological result of chondrosarcoma. We excluded the cases with incomplete data. Thirty-five in block resections were included in the final study population. In the rest of the cases, the sur...

Introduction. Giant cell tumors of soft tissue (GCTs) have a relatively low incidence and their low prognosis is reserved to local relapses and distant metastases. This type of pathology usually affects adults and the elderly and it is localized in the extremities, most frequently in the thigh. Materials and methods. GCT is a relatively low aggress...

One of the most common neoplasms in the world, ranking third, is the colorectal cancer. 96% of all cases of colorectal cancer are adenocarcinoma. The prognostic of this diagnostic is a bad one, with low 5-years survival rate. Although the most common locations for the metastases are the liver and the lungs, the bones can also be targeted (5.5%). We...
Positron emission tomography/computed tomography (PET/CT) represents an emerging imaging guidance modality that has been applied to successfully guide percutaneous procedures such as biopsies and tumour ablations. The aim of the present narrative review is to report the indications, advantages and disadvantages of PET/CT-guided procedures in the fi...

Data are lacking on RSB intensity and outcomes after pediatric heart transplantation. PHTS centers received a survey on RSB practices from 2005 to present. PHTS data were obtained for 2010-2013 and integrated with center-matched survey responses for analysis. Survey response rate was 82.6% (38/46). Centers were classified as low-, moderate-, and hi...
Introducción: La biopsia endomiocárdica (BEM) es un procedimiento de mucha utilidad para valorar el rechazo agudo en pacientes trasplantados, sin embargo, puede causar complicaciones. Objetivo: El propósito de este estudio es demostrar la eficacia y seguridad del ecocardiograma como guía para la BEM. Material y métodos: se realizó un análisis retro...
BACKGROUND & AIMS: Magnetic resonance elastography (MRE) and transient elastography (TE) are noninvasive techniques used to detect liver fibrosis in nonalcoholic fatty liver disease. MRE detects fibrosis more accurately than TE, but MRE is more expensive, and the concordance between MRE and TE have not been optimally assessed in obese patients. It ...
