Evaluation of RehaCom cognitive rehabilitation on different aspects of visual attention in patients with middle cerebral artery ischemia: A nonblinded randomized clinical trial.

Background: Cerebral ischemia or stroke is the second leading cause of death in the world, and most surviving patients suffer from long-term physical and cognitive disabilities, which create many social and economic problems for them and society. Visual attention impairment is a common cognitive complication among patients with cerebral ischemia, especially in the Middle Cerebral Artery (MCA). One way to improve attention in these patients is cognitive rehabilitation.

Diagnostic utility of a-methylacyl COA racemase in prostate cancer of the Iranian population.

Background: Considering the great variations in the reported prevalence of prostate cancer across the world possibly due to different genetic and environmental backgrounds, we aimed to determine the expression pattern and the diagnostic utility of α-methylacyl coenzyme A racemase (AMACR) among Iranian patients with prostate adenocarcinoma.

Materials And Methods: In this cross-sectional study, formalin-fixed paraffin-embedded tissues of 58 patients with a definitive pathologic diagnosis of prostatic adenocarcinoma were evaluated. The expression of AMACR, intensity, and extensity of its staining was determined in selected samples by immunohistochemical technique.

An Easy and Fast Method for Production of Chinese Hamster Ovary Cell Line Expressing and Secreting Human Recombinant Activin A.

Objective: Growth factors are key elements of embryonic stem cell (ESC) research. Cell line development in eukaryotes is a time-consuming procedure which usually takes 12-18 months. Here, we report an easy and fast method with which production of Chinese hamster ovary (CHO) cells that express and secrete recombinant Activin A, as a major growth factor in endo/mesoderm differentiation of embryonic stem cells is achieved within 3-4 weeks.

Artificial Ureter in Patients with Extensive Ureteral Damage.

Purpose: loss of significant lengths of ureter when substitution with bowel or bladder fails is a disaster in urology. This study is conducted to evaluate the results of subcutaneous nephron-vesical bypass (SNVB) in ureteral damage of different etiologies.

Materials And Methods: Seventeen SNVB were employed in patients with ureteral injuries.

Atorvastatin and prevention of contrast induced nephropathy following coronary angiography.

Background: Contrast induced nephropathy (CIN) is one of the most common complications after radiographic procedures using intravascular radiocontrast media. The aim of the current study was to assess the effect of atorvastatin on prevention of CIN in patients undergoing coronary angiography.

Materials And Methods: In a clinical trial study, 200 patients referred for angiography were randomly divided into two groups of using 80 mg atorvastatin and placebo before the procedure.
