Humans may be infected by different influenza A viruses--seasonal, pandemic, and zoonotic--which differ in presentation from mild upper respiratory tract disease to severe and sometimes fatal pneumonia with extra-respiratory spread. Differences in spatial and temporal dynamics of these infections are poorly understood. Therefore, we inoculated ferrets with seasonal H3N2, pandemic H1N1 (pH1N1), ...

Introduction: Eating fatty food is a common technique for decreasing extra cardiac activity, but sometimes patients refuse to eat fatty foods due to various reasons during myocardial perfusion imaging. The aim of this study is to introduce an alternative method for patients who are not able to use fatty foods to accelerate the transit of radiotracer from the liver. <stron...

abstract introduction: coronary artery disease (cad) is the main cause of mortality in industrial and developing countries. new risk factors including infections are under investigation as potential factors. one of these infectious agents is helicobacter pylori, which has been investigated in numerous studies. this study was designed in view of the controversies surrounding the impact of helico...

• Hospital infection control practice reflects the working assumption that extra pulmonary tuberculosis is not considered infectious. We describe how wholegenome sequencing identified the nosocomial transmission of extra-pulmonary Mycobacterium tuberculosis infection on our Infectious Diseases unit in Oxford, UK. • Suppurating wounds in tuberculosis constitute a hazard requiring risk assessment...

We present a patient with a large hiatal hernia resulting in duodenogastric reflux that was seen as abnormal activity below and behind the heart (retrocardiac) on SPECT images and on (99m)Tc-tetrofosmin cardiac SPECT raw-data projection images. Incidental findings such as extra- and retrocardiac activity in the thorax and abdomen should be included on all comprehensive cardiac SPECT reports.

familiarity with the normal and abnormal anatomy of the root canal system is essential for successful root canal treatment. the possibility of concomitant three-rooted and three- canalled maxillary and mandibular premolars are extremely rare. the purpose of this paper was to report a case with a three-rooted maxillary first premolar and two three-rooted mandibular premolars.
