Arson is a significant problem around the world, and is a crime which results in a low number of convictions. The scene of an arson can be varied, commercial, residential or national park, and recently cases have been identified which were initiated by a lit match. Matches can be recovered from a scene, usually in a burnt condition. The benefit of analysing unburnt matches has been researched p...

background: iron chelators are an important part of management of patients with thalassemia. it is prudent to compare efficacy of different iron chelators in treatment of iron overload in these patients who receive regular blood transfusion. we aimed to compare the efficacy and safety of available oral iron chelator; deferasirox (exjade®) with deferasirox (osveral®) in reducing iron overload in...

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 ...

Partial sequences of the RNase P RNA gene (rnpB) were obtained from a number of hemoplasmas and other Mycoplasma species. Phylogenetic analysis of these sequences showed that all hemoplasmas were present within a single clade and were most closely related to Mycoplasma fastidiosum, similar to the results found with 16S rRNA gene phylogeny.

A mutant strain deficient in RNase T was isolated and used to study the role of this enzyme in Escherichia coli. Strains lacking as much as 70% of RNase T activity, alone or in combination with the absence of other RNases, display normal growth properties. However, in cca strains, which lack tRNA nucleotidyltransferase, RNase T-deficient derivatives accumulate lower levels of defective tRNA and...
