INTRODUCTION The standardized diagnostic criteria for computed tomographic angiography (CTA) in diagnosis of brain death (BD) are not yet established. The aim of the study was to compare the sensitivity and interobserver agreement of the three previously used scales of CTA for the diagnosis of BD. METHODS Eighty-two clinically brain-dead patients(More)
INTRODUCTION Stasis filling, defined as delayed, weak, and persistent opacification of proximal segments of the cerebral arteries, is frequently found in brain dead patients. This phenomenon causes a major problem in the development of reliable computed tomographic angiography (CTA) protocol in the diagnosis of brain death (BD). The aim of our study was to(More)
Results of a blind test of photometric redshift predictions against spectroscopic galaxy redshifts obtained in the Hubble Deep Field with the Keck Telescope are presented. The best photometric redshift schemes predict spectroscopic redshifts with a redshift accuracy of |∆z| < 0.1 for more than 68 percent of sources and with |∆z| < 0.3 for 100 percent, when(More)
The aim of this paper is to discuss brachytherapy treatment and individual applicators suitable for unfavorably localized superficial malignant lesions. Techniques for manufacturing an individual applicator and clinical examples of its use for various locations of cancer are presented. This techniques are based on individual size and shape of the tumour.(More)
We use very deep U n GRI multi-field imaging obtained at the Keck telescope to study the evolution of the rest-frame 1700Å galaxy luminosity function as the Universe doubles its age from z∼4 to z∼2. We use exactly the same filters and color-color selection as those used by the Steidel team, but probe significantly fainter limits — well below L *. The depth(More)
OBJECTIVE To investigate whether assessment of C-reactive protein (CRP) and apolipoproteins, besides the traditional lipid profile, enhances the assessment process for the risk of acute coronary syndrome (ACS). METHODS The study group consisted of 220 consecutive patients admitted to hospital within the first 6 hours from the onset of chest pain. Patients(More)
PURPOSE Endobronchial brachytherapy (EB) is one way of treatment of patients with advanced lung cancer. Technological progress and the introduction of computed tomography for use in 3D planning allows one to define the area being treated very precisely, which gives an opportunity to extend survival, even in groups of patients receiving palliative care.

We have previously identified an excess population of predominantly red galaxies around a sample of 31 radio-loud quasars (RLQs) at 1 < z < 2. Here we show that these fields have a surface density of extremely red objects (EROs, with R − K > 6) 2.7 times higher than the general field. Assuming these EROs are passively evolved galaxies at the quasar(More)

We present a sample of 47 confirmed and 14 candidate Active Galactic Nuclei (AGN) discovered in the Canadian Network for Observational Cosmology field galaxy redshift survey (CNOC2). The sample consists of 38 objects identified from broad emission lines, 8 from narrow [Ne v] emission, and 15 candidates from Fe ii or Mg ii absorption lines, one of which has(More)
Summary Brain death is defined as the irreversible cessation of functioning of the entire brain, including the brainstem. Brain death is principally established using clinical criteria including coma, absence of brainstem reflexes and loss of central drive to breathe assessed with apnea test. In situations in which clinical testing cannot be performed or(More)
