Objective. To analyze the impact of patients' experience of care at their usual source of primary care on their choice of point of entry into cancer investigation process, time to diagnosis, and presence of metastatic cancer at time of diagnosis. Method. A questionnaire was administered to 438 patients with cancer (breast, lung, and colorectal) between 2011 and 2013 in four oncology clinics of ...

1. An electrophysiological method was used to estimate the half-times for sodium and potassium entry to, and efflux from, the extra-axonal space in peripheral nerve and central nervous connectives of two species of crustacean. Results from crab (marine) and crayfish (fresh water) were qualitatively similar. 2. Peripheral nerve showed no evidence for diffusion barriers, potassium entry and efflu...

Few studies have attempted to measure the effectiveness of computerised test-order entry systems to reduce test turnaround time and the extent to which improvements are sustained or continue over time. Further, a recent study has raised the possibility that such systems, which require significant work practice change, may be associated with an increase in mortality rates. Our study answered two...

The fluorescence of single terrylene molecules in a crystalline host is investigated at room temperature by scanning confocal optical microscopy. Photon arrival times are analyzed in terms of interphoton time distributions, second order correlation functions, and the variance of the photon number probability distribution. Antibunching at short times and bunching behavior for longer times is obs...

there has been a recent development and explosion of interest among academicians across a wide range of disciplines in the use of virtual class room. utilization of the virtual class room as a laboratory experimentation for teaching and learning has increased significantly in recent years as development tools for web based applications have become easier to use and computers have become more ca...

the perovskite-structured la2cuo4 nanoparticles (lco nps) have been synthesized via an ultrasonic-assisted co-precipitation route using octanoic acidas organic surfactant, and the phase composition, morphology, lattice parameters and size of nanoparticles  are characterized through fourier transform infrared spectroscopy (ft-ir), x-ray diffraction (xrd), scanning electron microscopy (sem) and t...

OBJECTIVE To evaluate the management of asthma attacks in children up to five years of age treated in the pediatric emergency room of a hospital in the metropolitan area of the city of Recife, Brazil, as well as to determine whether the way in which asthma attacks are managed can influence the duration of emergency room visits for such children. METHODS A descriptive, exploratory study employ...

blood specimens from 22 insulin dependent diabetic patient and 17 nontliabetic subject were collected im edta- tubes. quantitation of hb-al was performed by columne chromatography. the glycosylated hemoglobin component is increased in diabetic patient and found a significant correlation between hb-al concentration and blood glucose levels in all diabetic patients. the mean hb-al valve for diabe...
