BACKGROUND AND PURPOSE Endovascular and surgical options are both available for treatment of ruptured cerebral aneurysms. Knowledge of the costs relative to Medicare reimbursement for hospitalization of these patients is important for understanding the economic impact of these patients on hospitals. MATERIALS AND METHODS Using the NIS, we identified hospitalizations for clipping and coiling o...

BACKGROUNDS The efficacy of clipping for preventing the delayed bleeding after the removal of colon polyps is still controversial. In order to clarify this efficacy, a randomized controlled study was performed. METHODS One hundred and fifty-six patients with colon neoplasms (288 lesions) were enrolled in the study. The patients were randomly divided into two groups: clipping or nonclipping gr...

OBJECT Randomized trials have demonstrated a survival benefit for endovascular treatment of ruptured cerebral aneurysms. We investigated the association of surgical clipping and endovascular coiling with outcomes in subarachnoid hemorrhage (SAH) patients in a real-world regional cohort. METHODS We performed a cohort study involving patients with ruptured cerebral aneurysms, who underwent surg...

Steganalysis is the art of detecting covert communication and has become an important research field, in which some of steganographic tools provide the function of embedding secret messages into JPEG images. To detect JPEG stego-images, we will identify a novel statistical quantity in this paper. In general, the JPEG decompression process performs color clipping in lots of pixels, and thus, mes...

Interest in the use of summer fires to restore southern Great Plains prairie ecosystems infested with woody plants and cactus is increasing, but information regarding effects on target and nontarget plant species is needed before this practice can be recommended. We review effects of summer and winter fires on mortality and growth of honey mesquite (Prosopis glandulosa), prickly pear (Opuntia p...

There is increased interest in the use of summer-season fires to limit woody plant encroachment into grasslands, but effects of these fires on grasses are poorly understood. We quantified effects of repeated winter fires, repeated summer fires, and clipping (to simulate grazing) on aboveground total yield, live yield, and percentage of live tissue of C3 Texas wintergrass (Nassella leucotricha [...

Currently, the treatment of blood blister-like aneurysms (BBAs) of the supraclinoid internal carotid artery (ICA) is challenging and utilizes many therapeutic methods, including direct clipping and suturing, clipping after wrapping, clipping after suturing, coil embolization, stent-assisted coil embolization, multiple overlapping stents, flow-diverting stents, covered stents, and trapping with ...

Endoscopic clipping is an easy and effective technique for the treatment of various bleeding lesions in the upper and lower gastrointestinal tract. Several studies have shown comparable efficacy between clipping and contact thermal therapy for hemostasis of non-variceal upper gastrointestinal hemorrhage. Proficiency in clip application and endoscopic identification of lesions that are amenable ...

Introduction: Recent advancement of intravascular technique has minimized the operative invasiveness. In rivalry with this technique, aneurysmal clipping has become less and less invasive. Hitherto, three less invasive surgical approaches as supraorbital keyhole approach, lateral supraorbital keyhole approach, and pterion keyhole approach, have been proposed for the clipping of the anterior cir...

-A new line clipping algorithm against convex window based on a new approach for intersection detection is presented. Theoretical comparisons with Cyrus-Beck's algorithm are shown together with experimental results obtained by simulations. The main advantage of the presented algorithm is the substantial acceleration of the line clipping problem solution and that edges can be oriented clockwise ...
