BACKGROUND The left atrial posterior wall (PW) often contains sites required for maintenance of atrial fibrillation (AF). Electrical isolation of the PW is an important feature of all open surgeries for AF. This study assessed the ability of current ablation techniques to achieve PW isolation (PWI) and its effect on recurrent AF. METHODS AND RESULTS Fifty-seven consecutive patients with persi...
A survey of inbred strains of mice was made to determine whether the phenomenon of dermal hemorrhagic necrosis, as described in rabbits by Shwartzman, could be elicited in mice by bacterial polysaccharide preparations of demonstrated activity in rabbits. The polysaccharide preparations used were obtained from cultures of S. marcescens, S. typhosa, Ps. aeruginosa, and H. pertussis. Ten of the st...
Desmoplastic ameloblastoma is an unusual type of ameloblastoma with special histologic and radiographic features and anatomic distribution which differs from those in the classic type of ameloblastoma. The purpose of this article is to assist the dental community in better understanding of this variation of odontogenic tumor. We present a patient with desmoplastic and conventional variant of am...
The identification of bone lesions is crucial in the diagnostic assessment of multiple myeloma (MM). 68Ga-Pentixafor PET/CT can capture the abnormal molecular expression of CXCR-4 in addition to anatomical changes. However, whole-body detection of dozens of lesions on hybrid imaging is tedious and error prone. It is even more difficult to identify lesions with a large heterogeneity. This study ...
A new feature extraction technique for the detection of lesions created from mucosal inflammations in Crohn's disease, based on wireless capsule endoscopy (WCE) images processing is presented here. More specifically, a novel filtering process, namely Hybrid Adaptive Filtering (HAF), was developed for efficient extraction of lesion-related structural/textural characteristics from WCE images, by ...
We propose a novel approach to fully automatic lesion boundary detection in ultrasound breast images. The novelty of the proposed work lies in the complete automation of the manual process of initial Region-of-Interest (ROI) labeling and in the procedure adopted for the subsequent lesion boundary detection. Histogram equalization is initially used to preprocess the images followed by hybrid fil...
Purpose: Hybrid ablation (i.e. a combination of surgical thoracoscopic pulmonary vein (PV) isolation created using a box lesion on the posterior wall of left atrium followed by catheter ablation) has become a new technique for patients with persistent or long-lasting persistent atrial fibrillation (PeAF). However, EP findings following thoracoscopic ablation have not been described yet. Methods...

A portion of the DNA synthesized by HEp.2 cells after short incubation in the presence of BrdU bands in a CsCl gradient at a distinct peak of density 1.715-1.718 g/cm(3). Inhibition of DNA synthesis by methyl methanesulfonate results in an increased proportion of this "intermediate density" DNA. Cells labeled and subsequently chased in nonradioactive BrdU yield only hybrid DNA. Treatment with s...
background and objectives: study of deleterious effect of neurotoxins on the animals' brain is a fascinating research plan. in this project, the damage effect of colchicine on the hippocampal cornu ammonis 1 (ca1) was examined by the studying the hippocampal tissue. materials and methods: injections of colchicine (1-75 μg/rat, intra- hippocampal ca1) were performed in cannulated male wistar rat...
