PURPOSE To compare the distribution of different sized vessels using digital photographs of the ocular surface of diabetic and normal individuals. METHODS In this cross-sectional study, red-free conjunctival photographs of diabetic and normal individuals, aged 30-60 years, were taken under defined conditions and analyzed using a Radon transform-based algorithm for vascular segmentation. The i...

In sporadic Alzheimer’s disease (SAD), the classic (‘dense-cored’) β-amyloid (Aβ) deposits are aggregated around the larger blood vessels in the upper laminae of the cerebral cortex. To determine whether a similar relationship exists in familial AD (FAD), the spatial correlations between the diff use, primitive, and classic β-amyloid (Aβ deposits and blood vessels were studied in ten FAD cases ...

Background and Aims: Bilirubin has been considered an antioxidant that protects against atherosclerosis. The aim of this study was to evaluate the relationship of serum bilirubin level with the severity and complexity of coronary artery disease (CAD) and long-term outcome in the patients undergoing primary percutaneous coronary intervention (PCI). Materials and Methods: This prospective coho...

SYSTEMIC DISORDERS often cause pathological changes in the optic fundus. These changes have diagnostic value because of their empirical association with specific illnesses. The value of funduscopic examination would be even further increased by a better understanding of how certain of these fundic lesions are produced. With the ultimate object of investigating this problem, several photographic...

The present study proposes a catheter system with an expandable coil etched on a polyimide foil. The catheter system combines the advantages of a small insertion diameter when the coil is rolled up in a protective carrier sheath with an increased signal-to-noise ratio (SNR) and penetration depth when the coil is pushed out. After imaging, the coil can be retracted into the sheath and folded bac...

It has been proposed that directional coronary atherectomy (DCA) should be an intervention of choice in larger vessels as one can achieve a greater minimal luminal diameter with DCA than with percutaneous transluminal coronary angioplasty (PTCA). This in turn should translate into a higher success rate and may even reduce the restenosis rate. The aim of this study was to compare DCA versus PTCA...
