A rare case of partially thrombosed giant serpentine right middle cerebral artery aneurysm presented. A 26 year old man initially presented with headache and 3 months later developed neurological deficit. Various stages of clot with patent residual lumen seen on neuroimaging, led to the diagnosis. Catheter angiography is the investigation of choice for evaluating the location, flow dynamics and...

We propose a new method to construct a word list for rule induction from Japanese patent documents. For word segmentation in Japanese, statistical morphological analyzers have been used in many applications. However, the output of these morphological analyzers presents defects when analyzing unknown words, specifically words that contain Kanji/Katakana morphemes. Some words are overly segmented...

In the course of biological screening for herbicidal activity in synthetic compounds, various organic iodide complexes had marked defoliating properties when applied to leguminous test plants. Simple iodides such as the salts of alkali metals also caused defoliation. Although this effect has been reported in the patent literature (4, 8), our present investigation was undertaken principally to l...

granting of intellectual property rights on biological materials could be very contentious issue from cultural, legal, ethical and religious points of view. this could be even more complicated, once it acquires an international dimension. the agreement on trade related intellectual property rights (trips) is the latest international arrangement under which, a complex structure for international...

background: transcatheter occlusion of the patent ductus arteriosus (pda) is a minimally invasive treatment. the appropriate device size is chosen based on the angiographic measurement of the pda . the current study aimed to assess the relationship between the transthoracic echocardiographic (tte) measurements of the pda prior to the occlusion procedure and the actual size of the deployed devic...

in this retrospective study, 510 infants and children with patent ductus arteriosus (pda) who underwent surgery at the shahid rajai heart hospital in tehran were evaluated to determine the rate of surgical complications, morbidity and mortality. 30 patients (6%) developed minor to major complications postoperatively. four patients who had undergone pda ligation without division required reopera...

Abstract The present paper analyzes development patterns in research networks and technology as well their co-evolution by the example of currently highly transformative German automotive industry. We therefore introduce a consistent network-based approach for measuring change technological composition patents. Our results show that applied method is particularly useful identifying structural s...

BACKGROUND To our knowledge, no study has assessed the validity of family history data provided by probands with adult-onset dystonia. OBJECTIVE To measure the sensitivity and specificity of interviewing patients with primary adult-onset dystonia as a method for obtaining information on dystonia in first-degree relatives. PARTICIPANTS Seventy probands with primary adult-onset dystonia were ...

BACKGROUND The aim was to compare tuberculosis trends in Mexico and United States and to evaluate Mexican diagnostic methods and contact investigation. METHODS Retrospective comparative study of tuberculosis cases and incidence rates between both countries (1990-2010). Diagnostic methods and contact investigations were also evaluated for Mexico. Estimates were obtained from official websites....
