The biological effects of electromagnetic fields have seriously concerned the scientific community and the public as well in the past decades as more and more evidence has accumulated about the hazardous consequences of so-called "electromagnetic pollution." This theoretical model is based on the simple hypothesis that an oscillating external electric field will exert an oscillating force to ea...

Introduction: In radiation therapy of lung tumors, respiratory motion causes target moving, so a larger margin is needed to cover the clinical target volume (CTV). With the margin increasing, a larger volume of normal tissue will be exposed to high-dose.  In this study, dosimetric parameters of normal lung tissue were compared between gated and conventional radiotherapy (RT), u...

Dengue is the most important mosquito-borne disease in the Philippines, especially in Metropolitan Manila where communities are socially and economically diverse, and city governments struggle to provide basic services such as continuously available, piped water supply to residents. We examined responses to introducing water container management to control dengue vectors in two diverse communi...

introduction: we aimed to investigate of effect of left bundle branch block (lbbb) on perfusion and functional parameters in dipyridamole tc99m-mibi gated myocardial perfusion spect which may be helpful in interpretation of myocardial perfusion imaging. methods: we studied 70 patients with low pre-test probability of coronary artery disease in two groups:  35 patients with lbbb and  35 subjects...

introduction: we aimed to investigate the effect of right bundle branch block (rbbb) on perfusion and functional parameters in dipyridamole stress/rest tc99m-mibi gated myocardial perfusion spect (gspect) which may be helpful in interpretation of myocardial perfusion imaging. methods: we studied 73 patients with low pre-test likelihood of coronary artery disease in two groups:  38 patients with...

introduction: we investigated the difference in left ventricular ejection fraction (lvef) and end-systolic volume(esv) measured by gated myocardial perfusion spect (gspect) in the post-dipyridamole stress and rest periods, and compared the results with the perfusion patterns found in the conventional non-gated tomograms. methods: 297 consecutive patients were studied with post-stress and rest 9...
