Anomalous Wtb couplings in ?p collision at the LHC

Şahin B. | Billur A.A.

Article | 2012 | Physical Review D - Particles, Fields, Gravitation and Cosmology86 ( 7 )

We study the possibility for the process pp›p?p›pW -t(W +t¯)X with anomalous Wtb couplings in a model-independent effective Lagrangian approach at the LHC. We find 95% confidence level bounds on the anomalous coupling parameters for various values of the integrated luminosity. The improved constraints on the anomalous Wtb couplings have been obtained compared to current limits. © 2012 American Physical Society.

We examine the potential of the pp›p?p›pWqX reaction to probe anomalous WW? couplings at the LHC. We find 95% confidence level bounds on the anomalous coupling parameters with various values of the integrated luminosity. We show that the reaction pp›p?p›pWqX at the LHC highly improves the current limits. © 2011 American Physical Society.

The effects of zileuton and montelukast in reperfusion-induced arrhythmias in anesthetized rats

Gonca E.

Article | 2013 | Current Therapeutic Research - Clinical and Experimental75 , pp.27 - 32

Background: 5-Lipoxygenase is an enzyme involved in the synthesis of leukotriene eicosanoids from arachidonic acid. The therapeutic potential of zileuton, an inhibitor of 5-lipoxygenase, and montelukast, a cysteinyl leukotriene receptor antagonist, for the treatment of ischemia/reperfusion (I/R) injury of the heart has been proposed in a few studies. However, the effects of zileuton and montelukast on I/R-induced arrhythmias have not been determined. Objective: We assessed the possible protective effects of zileuton and montelukast against I/R-induced arrhythmias. Methods: Forty-five male Wistar albino rats were divided into 5 group . . .s, each containing 9 rats. Group 1: control, Groups 2 and 3: rats treated with montelukast (10 and 30 mg/kg IP); and Groups 4 and 5: rats treated with zileuton (1 and 3 mg/kg IV) 15 minutes before the induction of ischemia. Ischemia and reperfusion were induced by occluding the left main coronary artery of anesthetized rats for 6 minutes followed by reopening the artery for 6 minutes. Results: Both doses of zileuton decreased the mean [SE] arrhythmia score (zileuton 1 mg/kg: 1.4 [0.8]; zileuton 3 mg/kg: 1.3 [0.5] vs control: 2.9 [0.3]; P < 0.05), the duration of ventricular tachycardia, and the total length of arrhythmias, but montelukast was not effective to decrease the ventricular arrhythmias during the 6 minutes of reperfusion. Conclusions: The results indicate for the first time that zileuton exerts an antiarrhythmic effect at different doses and that montelukast is not effective against I/R-induced arrhythmias. These results indicate that zileuton may be a candidate for drug treatment of I/R-induced arrhythmias. © 2013 The Author Daha fazlası Daha az

Article | 2013 | Neurology Asia18 ( 4 ) , pp.415 - 418

Postural deformities like dropped head, camptocormia, and Pisa syndrome are seen in both Parkinson's disease and multiple-system atrophy (MSA). However, these features are relatively more common in MSA. These deformities may worsen during treatment and cause the patient distress. We report here two MSA patients. The first patient was a 53-year-old woman with severe bradykinesia, rigidity, and orthostatic hypotension developed dropped head after increasing her levodopa dose from 400 to 600 mg/day. This symptom improved when we reduced the levodopa dose back to 400 mg/day. The second was a 59-year-old woman with severe bradykinesia, r . . .igidity, and urinary incontinence who showed putaminal atrophy on magnetic resonance imaging. After Pisa syndrome was observed at her last follow-up visit, we decreased the pramipexole dose from 4.5 to 3 mg, and she improved. In conclusion, postural deformities in MSA patients may worsen with higher doses of dopaminergic treatment, and decreasing the dose may be the treatment of choice in these patients Daha fazlası Daha az

Lumbar extradural extraosseous schwannoma causing extensive compression of the vertebral body

Edebali N. | Açikgöz B. | Kalayci M.

Article | 2015 | Chirurgia (Turin)28 ( 2 ) , pp.75 - 77

Destroyed vertebral body and posterior bone elements of the spine by a schwannoma may cause unstability. Besides the removal of the tumour tissue, the surgeons have to correct these bone deformities using stabilization techniques. In this report we present a patient operated for a spinal schwannoma originating from L5 nerve root with involvement of nearly half of the L5 vertebra. During surgery, the internal cortical layer of the vertebral body was found intact so instrumentation and fusion were not performed in our case. The patient presented no tumour recurrence after more than three years of unproblematic follow-ups.

Study design:A combination of review of case notes and outpatient follow-up.Objective:To evaluate the effectiveness of the modified Girdlestones-Taylor procedure in patients with spinal cord injury (SCI).Setting:Princess Royal Spinal Injuries Centre (PRSIC), Northern General Hospital, Sheffield, UK.Methods:Nine patients with claw toe deformities to 27 toes were treated at the PRSIC from 1996 to 2005. After examination of their medical records, their toes were assessed for pain, residual deformity and stiffness. They were also asked to grade their satisfaction with the surgical outcome. The results were tabulated.Results:The average . . .age of our series of patients was 43.3 years. The mean time from injury to surgery was 20.4 years and the mean time from surgery to last follow-up was 37.3 months. All our patients had good to excellent results, with over 70% of the toes having excellent results.Conclusion:The modified Girdlestones-Taylor procedure for claw toe correction appears to be a safe and effective treatment for patients with SCI. © 2006 International Spinal Cord Society All rights reserved Daha fazlası Daha az

Article | 2008 | Australian Journal of Advanced Nursing26 ( 1 ) , pp.53 - 58

Objective: The purpose of this study was to identify knowledge deficits about the care of deceased patients among critical care nurses. Design: The research was conducted as a descriptive study in the adult intensive care units of a university hospital in Istanbul. The data were collected using a questionnaire. Setting: The study was conducted with nurses working in the medical and surgical intensive care units of a university hospital, including the coronary, neurosurgery, cardiovascular, post-anaesthesia and emergency intensive care units. Subjects: The subjects were 61 critical care nurses. Findings: The majority of nurse respond . . .ents (75.4%) did not have a certificate in intensive care nursing and 95.1% had not received education about the care of a deceased patient. There is no standard protocol at the hospital for deceased patient care. The majority of nurses stated they removed instruments, catheters, tubes, dressings from the body and cleaned drainage and secretions, but only 8.1% reported they dressed the patient in a clean gown and combed their hair. Of the nurse respondents, 24.5% did not provide emotional support to the individual's family. Conclusion: Nurses implemented appropriate clinical activities after death, however did not demonstrate appropriate support behaviours toward the patient's family or loved ones Daha fazlası Daha az

The influence of instructional interactions on students' mental models about the quantization of physical observables: A modern physics course case

Mental models are coherently organized knowledge structures used to explain phenomena. They interact with social environments and evolve with the interaction. Lacking daily experience with phenomena, the social interaction gains much more importance. In this part of our multiphase study, we investigate how instructional interactions influenced students' mental models about the quantization of physical observables. Class observations and interviews were analysed by studying students' mental models constructed in a modern physics course during an academic semester. The research revealed that students' mental models were influenced by . . .(1) the manner of teaching, including instructional methodologies and content specific techniques used by the instructor, (2) order of the topics and familiarity with concepts, and (3) peers. © 2016 IOP Publishing Ltd Daha fazlası Daha az
