background and aims: hepatitis c virus (hcv) can cause hepatocellular carcinoma (hcc) in a significant proportion (≈ 20 %) of individuals with chronic hcv infection (chc). currently, chc is treated with peginterferon and ribavirin, which depending on genotype approximately 50 to 70% of patients are cured. the so-called “extrahepatic hcv infection” or viral replication in regions of the body oth...

Background: Lithium is a therapeutic option for the treatment of the acute phase of the bipolar disorder and long-term management of this disorder. However,  it  is  estimated  that  10  to  60%  of  patients  do  not  properly response to this medication. Methods: To investigate the role of MARK2 gene in response to lithium, we genotyped the MARK2 rs10792421 polymorphism in Iranian bipolar pa...

The aim of current study was evaluating the frequency of clopidogrel resistance and its impact on clinical outcome of patients in Iranian patients. Patients undergoing percutaneous coronary intervention in Imam Hussein Medical center, Tehran, Iran, who received standard dosage of clopidogrel (Plavix®, Sanofi, France, 600 mg loading dose and 75 mg/day afterward) were recruited. Platelet aggregat...

A technique to study the dynamics of solving of a research task is suggested. The research task was based on specially developed software RightWrong Responder (RWR), with the participants having to reveal the response logic of the program. The participants interacted with the program in the form of a semi-binary dialogue, which implies the feedback responses of only two kinds “right” or “wrong”...

Background The optimal stimulation protocol for poor responder patients is a therapeutic challenge. GnRH antagonist protocol has been proposed as a potentially proper option for poor responders. Nevertheless, there is no significant difference in terms of clinical pregnancy and cancellation rates be tween the GnRH antagonist and agonist cycles. Therefore, this subset of patients might be the be...

The aim of the study was to investigate the value of intravoxel incoherent motion diffusion-weighted magnetic resonance imaging (IVIM-DWI) and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) in predicting the early and short-term responses to chemoradiotherapy (CRT) in patients with nasopharyngeal carcinoma (NPC).Forty-three NPC patients underwent IVIM-DWI and DCE-MRI at baseline...

BACKGROUND There have been few clinical studies on 10 mg atorvastatin as a starting dosage for treatment of hypercholesterolemia in type 2 diabetes mellitus (T2DM) patients. This retrospective study aims to evaluate the efficacy of 10 mg dosage of atorvastatin in clinical setting. METHODS One hundred five enrolled patients with high levels of low density lipoprotein cholesterol (LDL-C, > 100 ...
