BACKGROUND Under-ascertainment and over-ascertainment are common phenomena in surveillance and registry systems of health-related events. Capture-recapture is one of the methods which is applied to determine the sensitivity of surveillance or registry systems to recognize cancer cases. This study aimed to estimate the number of cancers using data available both in the Cancer Registry Center of ...

In northwestern Iran, magmatic activity occurred during three main intervals: The Cretaceous, Eocene, and Miocene-Quaternary. first two phases of are more consistent with arc-type magmatism on an active continental margin; whereas the last phase, which has calc-alkaline alkaline affinities, shows similarity to postcollisional magmatism. Magmatic belts mostly situated in northern eastern parts O...

Spermophilus xanthoprymnus (Bennett, 1835), the Asia Minor ground squirrel, is a group-living, diurnal, obligately hibernating marmotine squirrel. It inhabits the steppes and alpine meadows throughout central lowland and eastern highland Anatolia and adjacent Armenia and northwestern Iran.

Ardabil Province, northwestern Iran, is endemic for visceral leishmaniasis of Mediterranean type from many years ago. This situation might cause to underestimate other important diseases, which occur sporadically within the same area. In this case, a 6-year-old male patient in this area was treated as infected with visceral leishmaniasis initially with seropositive result for visceral leishmani...

As a result of a taxonomic and phylogenetic revision of Astragalus section Hymenostegis we identified a new species of Astragalus from northwestern Iran, namely A. remotispicatus spec. nov., which is described and illustrated here. It is morphologically similar to A. karl-heinzii in possessing a lax inflorescence. Phylogenetic inference of the nuclear ribosomal DNA internal transcribed spacer (...
