abstract background the aim of the present study was to determine the endocrine dysfunction in patients with major thalassemia, who receive hyper transfusion. materials and methods this cross sectional study was performed during one year, which included 65 major thalassemia patients (31 females and 34 males), aged between 14 month to 27 years old (median 10,3). growth assessment was measured by...

background recent studies regarding the effect of hydroxyurea (hu) in thalassemia have revealed favorable effects on the reduction of ineffective erythropoiesis. objectives the aim of the current study was to evaluate whether or not hu can have an effect on the gallstone formation rate in patients with beta-thalassemia intermedia (bti). patients and methods in this case control cross-sectional ...

conclusions single dose therapy of mtx has sufficient power and efficacy in the treatment of ectopic pregnancy, however in patients with higher serum level of β-hcg, the successful treatment increases by using double dose method. using double dose also could decrease the necessity of operation, re-administration of mtx, and duration of hospitalization. results results showed that the rate of su...

conclusions regarding the importance of metallo-beta-lactamase (mbl) produced by pseudomonas spp. isolated from hospitals, quick identification of clinical samples should be considered as an important and basic step to treat and control infections caused by pseudomonas spp. results strains with mic > 4 µg/ml were investigated by phenotypic and genotypic methods. in the current study the rate of...

Our objective was to study changes in EEG time-domain power spectral density (PSDt) and localization of language areas during covert object naming tasks in human subjects with epilepsy. EEG data for subjects with epilepsy were acquired during the covert object naming tasks using a net of 256 electrodes. The trials required each subject to provide the names of common objects presented every 4 se...

begin{abstract} the relations between the spectrum of the matrix $q+r$ and the spectra of the matrices $(gamma + delta)q+(alpha + beta)r-qr-rq$, $qr-rq$, $alpha beta r-qrq$, $alpha rqr-(qr)^{2}$, and $beta r-qr$ have been given on condition that the matrix $q+r$ is diagonalizable, where $q$, $r$ are ${alpha, beta}$-quadratic matrix and ${gamma, delta}$-quadratic matrix, respectively, of order $...

this study aims at testing the degree of stability for beta coefficient across time, depending on the information available from tehran bourse. where beta coefficient was calculated using the market model developed by sharp on 1963, which applies by performing a simple linear regression between the company’s and the market returns, where beta coefficient is the slope of this regression. in this...

Background and Objective: Beta-2 Microglobulin (β2M) is a middle molecular weight uremic toxin. Lack of β2M removal leads to β2M accumulation and amyloidosis in hemodialysis patients. The present research aims to determine the relationship between β2M and inflammatory factors, such as C-reactive protein (CRP), albumin, and high-density lipoprotein (HDL) in hemodialysis patie...

background: the comprehension processes are often inferred or explored indirectly through the assessment of the performance of the students on certain tasks. comprehension is typically measured by the techniques in which the test-taker reads a short text and then selects the correct answers in multiple choice questions, true/false and yes/no tasks or matching activities. purpose: a new approach...
