Serrated polyps have been recognised in the last decade as important premalignant lesions accounting for between 15% and 30% of colorectal cancers. There is therefore a clinical need for guidance on how to manage these lesions; however, the evidence base is limited. A working group was commission by the British Society of Gastroenterology (BSG) Endoscopy section to review the available evidence...

Abstract Triglycerides (TGs) are one of the main components glycerolipid family. Their task in cells is to store excess fatty acids. TG energy storage mainly concentrated adipocytes. TGs and free acids constitute majority (57.5%) skin surface lipids (SSLs). essential for formation water barrier. This work second part a global study that aims evaluate effect solar radiations on SSLs using vibrat...

Abstract The paper presents an experimental study on the effect of plastic fines content undrained behavior and liquefaction susceptibility sand–fines mixtures under monotonic loading. results triaxial compression tests conducted Hostun sand with varying amount (0–20%) type (kaolin calcigel bentonite) are presented. specimens were prepared different initial densities using moist tamping method ...

We present a computer-aided approach to segmenting suspicious lesions in digital mammograms, based on a novel maximum likelihood active contour model using level sets (MLACMLS). The algorithm estimates the segmentation contour that best separates the lesion from the background using the Gamma distribution to model the intensity of both regions (foreground and background). The Gamma distribution...

This paper proposes a novel stochastic-skill-level-based shared control framework to assist human novices emulate experts in complex dynamic tasks. The proposed aims infer stochastic-skill-levels (SSLs) of the and provide personalized assistance based on inferred SSLs. SSL can be assessed as stochastic variable which denotes probability that novice will behave similarly experts. We propose data...

Staphylococcus aureus is a significant human pathogen that is capable of infecting a wide range of host tissues. This bacterium is able to evade the host immune response by utilizing a repertoire of virulence factors. These factors are tightly regulated by various two-component systems (TCS) and transcription factors. Previous studies have suggested that transcriptional regulation of a subset o...

Convergent evolution occurs when the same trait arises independently in multiple lineages. In most cases of phenotypic convergence such transitions are adaptive, so finding the underlying molecular causes of convergence can provide insight into the process of adaptation. Convergent evolution at the genomic level also lends itself to study by comparative methods, although molecular convergence c...

The purpose of this study was to develop a new method for a peri-implantitis model in beagle dogs in which a stainless steel ligature (SSL) was used independently. A total of 36 Straumann dental implants were placed in six beagle dogs 1 month after all mandibular premolars were extracted. After 3 months, SSLs were placed in a submarginal position on the implants to induce peri-implantitis and w...

WiFi networks, which have been widely used along with the explosive increases in the supply of smartphones, can provide high network speeds but cannot prevent user information spills though rogue Access Points (APs). Therefore, the present paper proposes a method to exchange SSL session keys through more secure 3G networks to be used in WiFi networks in order to prevent such spills. In the prop...
