background: extended spectrum β-lactamases (esbls) and ampc β-lactamases enzyme are major sources of resistance to β-lactam antibiotics especially in enterobacteriaceae such as escherichia coli and klebsiella pneumoniae. increasing frequency of the co-existence of esbls with ampc-β-lactamases in bacteria is a serious threat for treating bacterial infections. conclusions: outbreak of isolates co...

background transfusion-induced iron overload leads to many complications in patients with β-thalassemia major. this study aimed to compare the level of iron stored in the liver and heart measured by mri t2 * with ferritin levels in these patients. materials and methods this study was done on 52 patients with β-thalassemia major aged 7 to 29 years. serum ferritin level was checked and heart and ...
