Presynaptic nicotinic acetylcholine receptors (nAChRs) on striatal synaptosomes stimulate dopamine release. Partial inhibition by the alpha3beta2-selective alpha-conotoxin-MII indicates heterogeneity of presynaptic nAChRs on dopamine terminals. We have used this alpha-conotoxin and UB-165, a novel hybrid of epibatidine and anatoxin-a, to address the hypothesis that the alpha-conotoxin-MII-insen...

The shoot apical meristem (SAM) comprises a group of undifferentiated cells that divide to maintain the plant meristem and also give rise to all shoot organs. SAM fate is specified by class III HOMEODOMAIN-LEUCINE ZIPPER (HD-ZIP III) transcription factors, which are targets of miR166/165. In Arabidopsis, AGO10 is a critical regulator of SAM maintenance, and here we demonstrate that AGO10 specif...

BACKGROUND Retrospective data on 165 patients who presented with a parotid mass and underwent surgery in our clinics during 2000-2009 were examined. The obtained data (demographic data, surgical procedures, histopathological diagnoses) were compared to similar studies to make contributions to the literature. MATERIALS AND METHODS Patients were classified according to their histopathological d...

OBJECTIVES We evaluated factors that influenced morbidity and mortality in patients undergoing completion pneumonectomy (CP). METHODS A retrospective review of a consecutive series of patients who underwent CP at six international centres. RESULTS In total, 165 CP were performed between March 1990 and December 2009: 152 for malignant disease and 13 for benign disease. Forty-two patients (25...

Given the recent occurrence of swine flu, many predictions have been made concerning future occurrence. In particular, a strong Fall 2009 outbreak was predicted, motivating the development of a swine flu vaccine to be distributed prior to this predicted onslaught. This is reminiscent of a swine flu scare that occurred in 1976, again predicted as a pandemic. Approximately 25% of the population w...

Digital imaging is becoming widely used in diagnostic radiology, and digital subtraction angiography (DSA) is now generally accepted [1-3]. Several studies have evaluated digital imaging using a computed radiography system for chest examinations [4-10] and for excretory urography [11] . This prospective study uses receiver operating curve analysis [12 , 13] to compare the diagnostic accuracy of...
