background: chromosome abnormality (ca) including sex chromosomes abnormality (scas) is one of the most important causes of disordered sexual development and infertility. scas formed by numerical or structural alteration in x and y chromosomes, are the most frequently ca encountered at both prenatal diagnosis and at birth. objective: this study describes cytogenetic findings of cases suspected ...

In the past decades, cardiovascular diseases were the most common causes of death around the world and in Iran (1, 2). Various factors play an important role in the incidence of CVD; such as environmental, personal as well as lifestyle. We studied the geographical distribution of 19142 CVD deaths f r o m 2004 -2010 in South Khorasan. The mean age of the deceased was 59.3±28.9 years. 28.5% death...

Resting cyst and motile thecate cell stages of three heterotrophic Protoperidinium oblongum, Protoperidinium sp and Protoperidinium claudicans were assessed. Cysts were isolated from sediment collected from southeast coast of Iran. Individual live cysts were incubated under optimal conditions for germination. Results showed that Protoperidinium oblongum cysts were pentagonal smooth walled and t...

For the lithostratigraphy and microbiostratigraphical studies, a stratigraphical section (named Dareh-Goshayesh) has selected and is located in southeast of Maragheh city, south of eastern Azerbaijan province in the northwest of Iran. The thickness of successions in the selected stratigraphic section is measured about 223.6 m. The mentioned studied stratigraphic section is composed of two clast...

Introduction: Cerebral venous-sinus thrombosis (CVST) is a life threatening condition that needs rapid diagnosis and treatment. It appears comparatively more common in Middle East and South Asia. Objectives: To determine the demographic, clinical patterns, etiologies and prognostic factors of CVST in the North East of Iran. Materials and Methods: All adult patients admitted with a documented di...

Resistance to frontline anti-malarial drugs, including artemisinin, has repeatedly arisen in South-East Asia, but the reasons for this are not understood. Here we test whether evolutionary constraints on Plasmodium falciparum strains from South-East Asia differ from African strains. We find a significantly higher ratio of non-synonymous to synonymous polymorphisms in P. falciparum from South-Ea...
