Preventable fatal injury during rally race: a multidisciplinary approach

2020

Abstract Introduction The motor vehicle crash (MVC) constitutes an important challenge for forensic pathology in order to identify the manner and cause of death. Our study focuses on a fatal accident during a rally race corresponding to MVC sub-category. Materials and method Postmortem computed tomography (PMCT) was performed before the conventional autopsy. Autoptic and PMCT data were compared. Data collection allowed analyzing biomechanical dynamics of the incident and post-traumatic injuries through qualitative-statistics and solicitation quantitative indices. Results Photo and circumstantial evidence analysis showed a wrong installation of double shoulder belt system of head and neck su…

Zur Frage der Darmkontrastierung in der abdominellen Computertomographie

1992

In 56 patients undergoing abdominal CT the gastrointestinal tract was defined by negative contrast instead of the conventional positive contrast from an iodine containing contrast medium. The contrast material was a 2 1/2% mannitol solution and was used for filling the rectum. Filling of the gastrointestinal tract was of similar quality to that obtained with positive contrast media. The number of artifacts due to high contrast boundaries was slightly greater with the negative contrast than it would have been with positive contrast. Differentiation of the gastrointestinal tract from other abdominal organs was equally good for both methods. The negative contrast method was poor in diagnosing …

Tumor enhancement at contrast-enhanced CT and Gd-enhanced MRI for the assessment of treatment response of hepatocellular carcinoma (HCC) after sorafe…

2012

Scopo: To investigate whether arterial enhancement of advanced HCC during pre-treatment and follow-up contrast-enhanced CT (CECT) or Gd-enhanced MRI (Gd-MRI) can be used to predict tumor response to sorafenib. Materiali e metodi: Seventeen patients (12M, 5F; mean age: 69 years) receiving sorafenib for inoperable HCC between 2007 and 2010 were included. Median interval time between pre-treatment and follow-up CECT or Gd-MRI was 160 days. Tumor arterial enhancement was measured at baseline and follow-up: (tumor attenuation/intensity on arterial phase – tumor attenuation/intensity on unenh! anced images)/(tumor attenuation/intensity on unenhanced images) x 100. Response was assessed according …

Identification of a Conserved HLA-A2-Restricted Decapeptide from the IE1 Protein (pUL123) of Human Cytomegalovirus

2002

Abstract Control of human cytomegalovirus (HCMV) infection is predominantly mediated by cytolytic CD8 + T lymphocytes (CTL). Among the roughly 200 HCMV-encoded polypeptides, the tegument protein pp65 (ppUL83) and the nonstructural IE1 protein are considered to be dominant CTL targets. Yet the importance of CTL against IE1 for protective immunity against HCMV reactivation and disease has remained elusive. Analyses have been difficult, as all MHC class I presented peptides of IE1 defined so far are located in parts of the protein that are variable between viral strains. In this study a conserved decameric peptide from IE1 (P6, IE1 354–363 ) that bound to HLA-A2 was identified. Using peptide-p…

Non invasive imaging of coronary arteries with 64-slice CT and 1.5T MRI: challenging invasive techniques

2007

Non-invasive coronary artery imaging challenges any diagnostic modality, because of the complex and tortuous anatomy and cardiac contraction and respiration. Therefore, non-invasive coronary imaging requires high spatial and temporal resolution. Our purpose is to discuss the feasible applications in coronary imaging of Magnetic Resonance Imaging and Multi-slice Computed Tomography (MSCT). Focus will be devoted to potential indications and clinical impact of MSCT because of the fast development and the important results recently reported, in particular with the recent introduction of 64-slice equipments. MSCT of the coronary arteries is a promising imaging modality for the assessment of coro…

Formación del profesorado desde el enfoque CTS

2001

Aunque las nuevas propuestas curriculares -fundamentadas en rigurosas investigaciones- están incorporando, en numerosos países, el enfoque CTS como un elemento esencial de la educación científica, se están detectando serias discrepancias entre los diseños curriculares y la actividad en el aula. Muy concretamente, puede afirmarse que la mayoría de los profesores de ciencias -incluidos los autores de textos escolares- sigue prestando una insuficiente atención a los contenidos CTS
