Optical Coherence Tomography and Fibrous Cap Characterization
The pathophysiology of acute coronary syndromes has long been associated with atherosclerotic plaque rupture. Inflammation, thinning, and disruption of the fibrous cap have been implicated with the final processes leading to plaque rupture, but confirmation of these mechanisms of coronary thrombosis in humans has been hampered by the lack of imaging methods with sufficient resolution to resolve fibrous cap characterization and thickness in vivo. Intravascular optical coherence tomography (OCT) provides images with micron-level axial and lateral resolution, enabling detailed visualization of micro-structural changes of the arterial wall. The present article provides an overview of the potential role of OCT in identifying and characterizing fibrous cap morphology, thickness, and inflammation in human coronary plaques
Peak cap stress calculations in coronary atherosclerotic plaques with an incomplete necrotic core geometry
The academy's new electronic order? Open source journals and publishing political science.
For many years, the dissemination of academic research has been controlled by commercial publishers. However, in light of the continuing inflation of subscription prices for scholarly journals, many academics are investigating open access publishing over the Internet. Although most advanced in the natural sciences, given its essentially political character, open access publishing should also be carefully considered by political scientists (and associated disciplines). This article explores open access publishing and suggests the reputational pay-off of 'normal' publishing can easily be maintained in the open access realm
Markers of inflammation collocate with increased wall stress in human coronary arterial plaque

3D computational parametric analysis of eccentric atheroma plaque: influence of axial and circumferential residual stresses
Genetic association studies in patients with traumatic brain injury
Traumatic brain injury (TBI) constitutes a major cause of mortality and disability worldwide, especially among young individuals. It is estimated that despite all the recent advances in the management of TBI, approximately half of the patients suffering head injuries still have unfavorable outcomes, which represents a substantial health care, social, and economic burden to societies. Considerable variability exists in the clinical outcome after TBI, which is only partially explained by known factors. Accumulating evidence has implicated various genetic elements in the pathophysiology of brain trauma. The extent of brain injury after TBI seems to be modulated to some degree by genetic variants. The authors' current review focuses on the up-to-date state of knowledge regarding genetic association studies in patients sustaining TBI, with particular emphasis on the mechanisms underlying the implication of genes in the pathophysiology of TBI.
