In recent years, computer-aided automatic polyp segmentation and neoplasm detection have been an emerging topic in medical image analysis, providing valuable support to colonoscopy procedures. Attentions paid improving the accuracy of segmentation. However, not much focus has given latency throughput for performing these tasks on dedicated devices, which can be crucial practical applications. T...

In order to characterize the dynamics of the interaction between the emergent membrane translocated exoprotein and the components of Bacillus subtilis cell wall, we examined the kinetics of the in vitro refolding of levansucrase and alpha-amylase, at pH 7 and 37 degrees C, in the presence of polyphosphates (polyP) of various chain lengths (2</=n</=65). These soluble anionic polymers are conside...

m h m a s b The ASGE Technology Committee provides reviews of existing, new, or emerging endoscopic technologies that have an impact on the practice of GI endoscopy. Evidencebased methodology is used, performing a MEDLINE literature search to identify pertinent clinical studies on the topic and a MAUDE (U.S. Food and Drug Administration Center for Devices and Radiological Health) database searc...

Colonoscopy is one of the best methods for screening colon cancer. A variety of research groups have proposed methods for automatic detection of polyps in colonoscopic images to support the doctors during examination. However, the problem can still not be assumed as solved. The major drawback of many approaches is the amount and quality of images used for classifier training and evaluation. Our...

Automatic polyp segmentation has proven to be immensely helpful for endoscopy procedures, reducing the missing rate of adenoma detection endoscopists while increasing efficiency. However, classifying a as being neoplasm or not and segmenting it at pixel level is still challenging task doctors perform in limited time. In this work, we propose fine-grained formulation problem. Our aims only segme...

BACKGROUND AND OBJECTIVES Primary care physicians initiate colorectal cencer (CRC) screening and manage health care issues that present from these procedures. Quality of colonoscopy services can be determined by a set of indicators. The purpose of this study was to identify the quality of colonoscopy services provided for patients of family physicians in the Iowa Research Network (IRENE). Quali...

The aim of the present study was to investigate the clinical significance of abnormal sugar-chain glycoprotein tumor abnormal protein (TAP) in the screening of common digestive tract pre-cancer colon adenocarcinoma lesions. A total of 50 colitis patients, 50 colon polyp patients and 50 colon adenocarcinoma patients admitted to our hospital from March, 2012 to May, 2014 were included. Fresh bloo...

BACKGROUND Colonoscopy may fail to detect neoplasia located on the proximal sides of haustral folds and flexures. The Third Eye Retroscope (TER) provides a simultaneous retrograde view that complements the forward view of a standard colonoscope. OBJECTIVE To evaluate the added benefit for polyp detection during colonoscopy of a retrograde-viewing device. DESIGN Open-label, prospective, mult...
