Iran J Med Sci March 2017; Vol 42 No 2 221 Dear Editor, A 46-year-old woman presented to the Urology Clinic, Department of Urology, Hitit University Çorum Training and Research Hospital, Çorum, Turkey, with right-flank pain of 4 months’ duration. The patient’s medical history was unremarkable. Plain radiography of the kidney, ureter, and bladder demonstrated ureteral stones in the right distal ...

Retrieval of episodic memories depends on the successful "re-collection" of event features, such as the time, place, people, thoughts, and feelings associated with a past experience.In neuroimaging studies, ventral regions of the posterior parietal cortex (vPPC) are particularly active when episodic memories are successfully retrieved. A review of the neural correlates of episodic retrieval is ...

This paper presents an evolved rule-based tool for mammography interpretation denominated “COBRA: Catalonia online breastcancer risk assessor.” COBRA is designed to aid radiologists in the interpretation of mammography to decide whether to perform a biopsy on a patient or not while providing a human-friendly explanation of the underlying reasoning. From a diagnostic point of view, the tool exhi...

Both sea snakes and cobras have venoms containing postsynaptic neurotoxins. Comparison of the primary structures indicates many similarities, especially the positions of the four disulfide bonds. However, detailed examination reveals differences in several amino acid residues. Amino acid sequences of sea snake neurotoxins were determined, and then compared to cobra neurotoxins by computer model...

We describe a new species of giant spitting cobra, Naja ashei sp. nov., from eastern and north-eastern Africa. The species was previously regarded as a colour phase of the black-necked spitting cobra, N. nigricollis. However, mtDNA sequence data show it to be more closely related to N. mossambica than N. nigricollis. The new species is diagnosable from all other African spitting cobras by the p...

Acetylcholinesterase purified from cobra (Naja naja) venom exhibits a serotonin-sensitive aryl acylamidase activity. Both acetylcholinesterase and aryl acylamidase activities co-eluted in column chromatographic procedures (Sephadex G-75 and Zinc-Sepharose), co-migrated on polyacrylamide gel electrophoresis, co-immunoprecipitated by anti-snake venom antibody and showed the same heat denaturation...

This document describes a new approach that explores the use of Semantic Web languages in building an architecture for supporting context-aware systems. This new architecture called Context Broker Architecture (CoBrA) differs from other architectures in using the Web Ontlogy Language OWL for modeling ontologies of context and for supporting context reasoning. Central to our architecture is a br...

This article provides an overview of the first results from archaeological investigations at Wadi el-Sheikh in Egypt by the University of Vienna Middle Egypt Project. Chert was an important raw material used to produce tools, implements and jewelry in ancient times. Wadi el-Sheikh was exploited over thousands of years as it was probably the most important source of chert in Pharaonic civilizati...

Orthorhombic crystals of cardiotoxin-analogue III from Taiwan cobra have been grown from 2-methyl-2,4-pentanediol solution. The space group is P222 with 2 molecules/asymmetric unit. Several different crystal forms of phospholipase A2 from Taiwan cobra have been produced with or without Ca2+ ion. One of them, grown from 30 mM sodium cacodylate buffer (pH 6 to 7) and 30% 2-methyl-2,4-pentanediol ...
