realizing the cause of cushing's syndrome (cs) is one of the most challenging processes in clinical endocrinology. the long high dose dexamethasone suppression test (standard test) is costly and need an extended inpatient stay. in this study we want to show the clinical utility of the overnight 8 mg dexamethasone suppression test (dst) for differential diagnosis of cs in a referral center. retr...

a survey on the genus exallonyx kieffer, 1904 (hymenoptera: proctotrupidae) was conducted in northern iran. the specimens were collected using malaise traps during 2010–2011. the genus exallonyx and six species were collected and identified for the first time from iran: exallonyx ater (gravenhorst, 1807), e. brevicornis (haliday, 1839), e. formicarius kieffer, 1904, e. ligatus (nees, 1834), e. ...

introduction :  despite  recent  advances  in  treatment  of  oral  cancer,  it  still causes high rates of mortality and morbidity worldwide. delays in diagnosis and treatment of these cancers greatly affect the prognosis.  this study aimed to assess the treatment delay and its relation to diagnostic delay among oral cancer patients in tehran, iran. materials and methods : we studied 100 patie...

background: cd52 is a small glycoprotein with a gpi anchor at its c-terminus. cd52 is expressed by normal and malignant t and b lymphocytes and monocytes. there are detectable amounts of soluble cd52 in plasma of patients with cll and could be used as a tumor marker. although the biological function of cd52 is unknown but it seems that cd52 may be involved in migration and activation of t-cells...

iniencephaly is a rare kind of neural tube defect that is classified into two types of iniencephaly apertus and iniencephaly clausus. this anomaly could be diagnosed prenatally by obstetric ultrasonography and terminated by therapeutic abortion; however, it could be undiagnosed until birth similar to our case due to the abnormal position of the fetus or lack of experience of the sonographer. du...

objective: the goal of this study was to assess the utility of serum uric acid in preeclampsia diagnosis and its correlation with some maternal and fetal outcomes. materials and methods: a case-control study was performed on 26 term pregnant women with preeclampsia and 52 normal pregnant women. serum uric acid, platelet count, hematocrit, gestational age, and birth weight of all patients were m...

Image quality in diagnostic x-ray imaging is ultimately limited by the statistical properties governing how, and where, x-ray energy is deposited in a detector. This in turn depends on the physics of the underlying x-ray interactions. In the diagnostic energy range (10-100 keV), most of the energy deposited in a detector is through photoelectric interactions. We present a theoretical model of t...
