In recent years, there has been a great deal of attention toward free radicals, reactive oxygen species (ROS) generated by exposure of crop plant cells to physical radiations. Henceforth, the current study was planned to compare oxidative stress and mutagenic potential of different irradiation doses of fast neutron (FN) and UV-B on meiotic-pollen mother cells (PMCs), pollen grains (PGs) and see...

UNLABELLED The association between main pulmonary artery (MPA) size and pulmonary arterial hypertension (PAHTN) is well established; however, the clinical utility of routine measurement of MPA is uncertain due to considerable overlap between normal patients and those with pulmonary hypertension. The lack of diagnostic accuracy could be further degraded by variability among the radiologists. It ...

SUMMARY The state of the art in promoter modeling for higher eukaryotes is predicting not single transcription factor binding sites (TFBSs), but their combinations. The new tool utilizes a previously developed method of distance distributions of TFBS pairs. We model the random distribution of distances and compare it with the distribution observed in the query sequences. Comparison of the profi...

OBJECTIVES To conduct a pilot study to examine physician patient interaction when elderly patients are accompanied during a medical visit. METHODS This was a study in which 30 patients were randomly assigned to be accompanied (13) or unaccompanied (17) during a regular medical visit to their physician. Visits were tape recorded, transcribed, and coded with the Measure of Patient-Centered Comm...
