Esophageal Prosthesis For Refractory Gastresophageal Reflux Disease Prevention

Abstract

We present a fuzzy rule-based system for epileptic seizure onset detection. Two features based on temporal evolution of seizure in electroencephalogram ͑EEG͒ were extracted from intracranial EEG ͑iEEG͒ recordings. Features extracted from multichannel EEGs were combined using fuzzy algorithms in feature domain as well as in spatial ͑channels͒ domain. Fuzzy rules were derived from experts' knowledge and reasoning. Finally, a predefined threshold was used to make the final decision. A total of 40.46 h of iEEG recordings ͑obtained from Freiburg Seizure Prediction EEG database͒ selected from 13 patients having 19 seizures was used for the system evaluation. The overall detection rate of 100% was achieved with false detection rate of 0.275/h and the average detection latency of 26.858 seconds.

Fine-Tuning the Nanostructured Titanium Oxide Surface for Selective Biological Response

“…With the application and invention of coronary stents, a dramatic decrease in bypass surgeries was reported. Drug-eluting stents (DESs) were developed to replace conventionally used bare metal stents (BMSs), as they caused complications such as reblockage of vessels, called in-stent restenosis. , After stent implantation, approximately 20–30% of patients experienced in-stent restenosis . This post-implant complication is due to vascular smooth cell proliferation, migration, and growth of the arterial inner wall because of the insufficient biocompatibility of stent material .…”
