In this regard a study designed to investigate the distribution and fauna of ticks in the Alashtar county in Iran from April and March 2014. Methods Ticks were collected from livestock farms and facilities from selected rural and geographically location in the Alashtar co...

Metadon persicus Gilasian & Reemer sp. nov. is described, based on a single female specimen from the Zagros mountains in Iran. Morphological variation among the members of the genus Metadon Reemer and their distribution in the world are discussed. Photographs of the new species are provided. The subfamily Microdontinae represents a new taxon for southwestern Asia and the genus Metadon is report...

This study illustrates the use of an Association Rule General Analytic System (ARGAS) for analyzing non-numeric data. Previous research by Parente, Finley and Megalis (2021) showed how ARGAS approach could be used to test hypotheses in conventional experimental designs. can exploratory settings such as single-case research, assessing organization multi-trial learning experiments, analysis socia...

Platelet aggregation inhibitory effect and anticoagulant properties of fractions separated from the venoms of Cerastes persicus fieldi and Echis carinatus were investigated. The partial fractionation was performed on a Sephadex G-100 column. Two fractions separated from Cerastes persicus fieldi showed anti platelet aggregation activity on ADP (200 μM)-induced platelet aggregation (ca 80% inhibi...

The pigeon tick, Argas reflexus, has been found in old buildings in the centre of Lublin (51°24'N latitude). This is the easternmost locality of this tick species in Poland.

Sturgeons are ancient and commercial fishes which posses’ primitive characteristics and due to their great inflections are able to live in both freshwater and marine environments. So their kidney has great ability for adaptation process. In order to find the structure and distribution of kidney nephrons in juvenile Huso huso and Acipensr persicus, sampling of head, body and caudal parts of kidn...
