Purpose: Oncoming headlight glare (HLG) reduces the visibility of objects on the road and may affect the safety of nighttime driving. With cataracts, the impact of oncoming HLG is expected to be more severe. We used our custom HLG simulator in a driving simulator to measure the impact of HLG on pedestrian detection by normal vision subjects with simulated mild cataracts and by patients with rea...

The cerebral aneurysm 'clip scissoring' phenomenon resulting from clip blade twisting is an unpredictable surgical complication. Additionally, incomplete clipping resulting from the presence of an atherosclerotic wall in the neck of the aneurysm can also cause unforeseen problems. Here, the authors present an unusual case of incomplete clipping of a large, atheromatous aneurysm resulting from c...

OBJECTIVE To perform a comparative study between two groups of populations, titanium (T) group versus stainless steel (S) group, who were clipped with titanium and stainless steel materials, respectively, the incidence of regrowth from the original aneurysms, the clip slippage, and post-clipping seizure attack were analyzed. The patients were followed more than 5 years after microsurgical cereb...

A methodology is proposed to identify narrative peaks in video clips. Three basic clip properties are evaluated which reflect on video, audio and text related features in the clip. Furthermore, the expected distribution of narrative peaks throughout the clip is determined and exploited for future predictions. Results show that only the text related feature, related to the usage of distinct word...

The unique composition and spatial arrangement of RNA-binding proteins (RBPs) on a transcript guide the diverse aspects of post-transcriptional regulation. Therefore, an essential step towards understanding transcript regulation at the molecular level is to gain positional information on the binding sites of RBPs. Protein-RNA interactions can be studied using biochemical methods, but these appr...

PURPOSE To optimize the multi CTA (MSCTA) protocol, the influence of pitch, kilovoltage peak (kVp), reconstruction algorithm, type, and orientation of the clip on clip-induced artifacts was investigated in a phantom study. Also, the influence of kVp, concentration of contrast material, and clip orientation in clipped patients was studied. METHODS A phantom containing a clip was scanned with v...

Certain HLA-DR alleles confer strong susceptibility to the autoimmune disease rheumatoid arthritis (RA). We compared RA-associated alleles, HLA-DR*0401, HLA-DR*0404, and HLA-DR*0405, with closely related, non-RA-associated alleles, HLA-DR*0402 and HLA-DR*0403, to determine whether they differ in their interactions with the class II chaperone, invariant chain (Ii). Ii binds to class II molecules...
