polymers, ϳ 70 mer to 250 mer, are more effective in abrogating tissue factor pathway inhibitor–anticoagulant activity. In the case of fibrin clot stabilization, polyP polymers shorter than 100 mers had no influence on fibrin clot turbidity whereas Ն 250 mer support maximal turbidity increase. Interestingly, very short phosphates, particularly PPi, effectively block the polyP-mediated enhanceme...

an inositol ring. Diphosphoinositol pentakisphosphate (IP7), the most abundant inositol pyrophosphate, is synthesized on phosphorylation of inositol hexakisphosphate (IP6) by IP6 kinases, of which there are 3 mammalian isoforms (IP6K1/2/3) and a single yeast isoform. Yeast lacking IP6 kinase are devoid of polyP, suggesting a role for IP6 kinase in maintaining polyP levels. We theorized that the...

BACKGROUND The purpose of this study was to determine the frequency of Serrated polyps of colonic polyps samples in Hazrat_e Rasoul_e Akram Hospital over ten years. MATERIALS The target group in this study was patients with colonic polyps in Hazrat_e Rasoul_e Akram Hospital. Pathologic evaluation of these patients was done. Serrated polyps, by location, gender, age and type of polyps were div...

Listening to music and conversing with friends are processes that are made possible by human audition. The primary conduit for such aural perception in humans is the ear. The human ear is a complex system that encodes sounds that travel through it. Due to its physical construction, the ear gives rise to many interesting aural phenomena. In this paper, the physics of the ear are discussed, and s...

A fibro-epithelial polyp is the most common epithelial benign tumor of the oral cavity. Such a polyp is of mesodermal origin and it is a pink, red, or white knob-like painless growth that is sessile or pedunculated. A fibro-epithelial polyp commonly occurs on buccal mucosa, the tongue, or the gingiva. A fibro-epithelial polyp is an inflammatory hyperplastic lesion in response to chronic irritat...

Short chain polyphosphates (polyP) are pro-coagulant and pro-inflammatory platelet released inorganic polymers. The platelet chemokine platelet factor 4 (PF4) binds to lipid A on bacteria, inducing an antibody mediated host defense mechanism, which can be misdirected against PF4/heparin complexes leading to the adverse drug reaction heparin-induced thrombocytopenia (HIT). Here, we demonstrate t...

This paper summarizes the method of polyp detection in colonoscopy images and provides preliminary results to participate in ISBI 2015 Grand Challenge on Automatic Polyp Detection in Colonoscopy videos. The key aspect of the proposed method is to learn hierarchical features using convolutional neural network. The features are learned in different scales to provide scale-invariant features throu...

A 68-year-old Japanese woman presented with a solitary pedunculated polyp in the duodenum. Endoscopic ultrasonography showed multiple cystic structures in the polyp. The polyp was successfully resected by endoscopic snare polypectomy and pathologically diagnosed as Brunner's gland hamartoma. Because hamartomatous components were not identified in the stalk of the polyp, we speculate that the st...

BACKGROUND The prevalence of nasal polyp in the population has been estimated to be 0.5-4%. It is noticed that nasal polyp could have a negative impact on the patient's quality of life and indubitably exert a substantial cost on the society. It is observed that, in some cases, complete cure may not be achieved and relapse can occur. In Iranian traditional medicine (ITM), nasal polyp is called "...

We report herein the case of a lobulated and pedunculated hyperplastic polyp in the third portion of the duodenum causing anemia and occult blood in stools, which was detected by capsule endoscopy (CE) and treated with snare polypectomy. A 71-year-old man was referred to our hospital because of anemia and occult blood in stools. Three months earlier, he had been admitted to another hospital bec...
