BACKGROUND The composite variability index (CVI), derived from the bispectral analysis (BIS), has been designed to detect nociception; however, there is no evidence that bilateral BIS and CVI show intrapatient reproducibility or variability. METHODS We conducted an observational study in patients who underwent for total knee arthroplasty. A BIS Bilateral Sensor was applied and continuously re...

abstract introduction: it is demonstrated that the degree of clinical improvement in parkinson's disease (pd) achieved by deep brain stimulation (dbs) is largely dependent on the accuracy of lead placement. in addition, individual variability in the situation of subthalamic nucleus (stn) is responsible for spatial inter-individual fluctuations of the real patient's target. objective: our study ...

There is increasing evidence that not only the elevation of systolic and diastolic blood pressure (BP) but also the increase in BP variability (or fluctuation) are associated with hypertensive organ damages and the morbidity and mortality of cerebrovascular and cardiovascular events. However, the molecular mechanism whereby the increase in BP variability aggravates hypertensive organ damages re...

neuroblastoma is a common tumor in pediatric cancer and which might present with usual or unusual clinical features. one of the rare clinical finding of neuroblastoma is paraneoplastic syndromes. we report a two year-old girl with presentation of bilateral ptosis and abdominal pain which was diagnosed as having neuroblastoma. our case is a very rare case of neuroblastoma accompanied by bilatera...

This paper addresses the problem of head pose estimation in order to infer non-intrusive feedback fromusers about gaze attention. The proposed approach exploits the bilateral symmetry of the face. Size and orientation of the symmetrical area of the face is used to estimate roll and yaw poses by themean of decision tree model. The approach does not need the location of interest points on face an...

We present an empirical investigation of the hypotheses that exchange rate uncertainty may have an impact on both the volume and variability of trade flows by considering a broad set of industrial countries’ bilateral real trade flows over the period 1980–1998. Similar to the findings of earlier theoretical and empirical research, our first set of results shows that the impact of exchange rate ...

We present an empirical investigation of the hypotheses that exchange rate volatility may have an impact on both the volume and variability of trade flows by considering a broad set of industrial countries’ bilateral real trade flows over the period 1980–1998. Similar to the findings of earlier theoretical and empirical research, our first set of results shows that the impact of exchange rate u...

OBJECTIVES The objective of this study was to document and explain bilateral differences in the Q angle. MATERIALS AND METHODS Two hundred limbs of healthy adult Indian volunteers were studied. The Q angle was measured using a goniometric method with the subjects supine, quadriceps relaxed and lower limbs in neutral rotation. The relative lateral placement of the tibial tuberosity with respec...
