INTRODUCTION AND OBJECTIVES Postoperative atrial fibrillation is a common complication of carrying out cardiac surgery with extracorporeal circulation (ECC). The aim of this study was to determine whether preoperative left atrial contractile dysfunction, as assessed by tissue Doppler echocardiography, is associated with the development of postoperative new-onset atrial fibrillation (PAF). MET...

The epidemiology of laboratory-confirmed respiratory syncytial virus (RSV) infections in young children has not recently been described in England, and is an essential step in identifying optimal target groups for future licensed RSV vaccines. We used two laboratory surveillance systems to examine the total number and number of positive RSV tests in children aged <5 years in England from 2010 t...

We have investigated the Quasi Periodic Oscillation (QPO) properties of the transient accreting X-ray pulsar XTE J1858+034 during the second outburst of this source in April-May 2004. We have used observations made with the Proportional Counter Array (PCA) of the Rossi X-ray Timing Explorer (RXTE) during May 14-18 2004, in the declining phase of the outburst. We detected the presence of low fre...

BACKGROUND The objectives of this study were to determine the incidence, outcome and risk factors for HBV reactivation in HBsAg positive breast cancer patients while on anthracycline -based adjuvant chemotherapy. METHODS We retrospectively reviewed the records of 2,431 patients with early breast cancer who received adjuvant chemotherapy from March 2001 to December 2005. Among these patients, ...

The bifurcation transition is studied for the onset of intermittency analogous to the Pomeau-Manneville mechanism of type I, but generalized for the presence of a quasiperiodic external force. The analysis is concentrated on the torus-fractalization (TF) critical point that occurs at some critical amplitude of driving. (At smaller amplitudes the bifurcation corresponds to a collision and subseq...

We present the results of our search for optical counterparts to high-mass X-ray transient sources discovered by various X-ray missions. We obtained CCD images of the X-ray fields through BVR and Hα filters in order to identify early-type stars in the R − Hα versus B − V colour-colour diagram. We also obtained medium-resolution spectroscopy of the candidates in order to confirm the presence of ...
