Computational and Biochemical Approaches to Molecular Epidemiology

Mining activity in Butte, Montana has taken place, or continues to take place, within the urban residence of Butte itself. This has led to urban areas with high concentrations of toxic metals such as arsenic, lead, copper, zinc, mercury and cadmium. Advances in protein study and gene sequencing has opened the possibility of finding molecular biomarkers whose presence, absence or morphological changes could indicate disease processes in populations exposed to environmental toxins. While in principle, biomarkers can be any chemicals or metabolites, as well as proteins and genes that are indicative of exposure to xenobiotics, this study seeks to identify changes in cellular pathways that suggest chronic (or acute) exposure to low-levels of metals associated with historical mining activities on the Butte Hill that could cause oxidative stress or other stress to the cell.

E-learning - an approach to teaching art history in the Internet age

Der erste Universitätskurs in Norwegen, der komplett via Internet unterrichtet wird, wird in Kunstgeschichte angeboten. Dieses Projekt wurde im März 2000 mit einem Einführungskurs in die Kunstgeschichte gestartet. Aufgrund seiner modularen Struktur, visuell ansprechender Präsentationen, fachbezogener Ansätze sowie Möglichkeiten eines zweiseitigen Kommunikationsaustausches, kann das Interesse und der Einbezug der Studenten während der zweijährigen Dauer des Kurses aufrecht erhalten werden.

Anterior approaches to the acetabulum

Since the 1960s the ilioinguinal approach by Letournel with the three anatomic windows has been successfully established for the treatment of acetabular fractures involving predominantly the anterior column. The previous standard approach, the iliofemoral approach by Smith-Petersen, is still used for the therapy of anterior wall or isolated femoral head fractures. The increase in acetabular fractures in the elderly with lateral compression fractures after lateral falls, characterized by medial displacement of the quadrilateral plate and superomedial dome impaction, led to the use of the intrapelvic modified Stoppa approach with or without the first window of the ilioinguinal approach in the 1990s. To combine the advantages of the second and third windows of the ilioinguinal approach and the medial view of the modified Stoppa approach the Berne research group recently introduced the pararectus approach in acetabular surgery, which can be used as a less invasive acetabular surgical (LIAS) technique especially in the elderly.
