Background: Magnetic Resonance imaging (MRI) is a valuable diagnostic tool by its non-invasive/non-ionizing nature.
Objective: This study aims to determine justification of MRI in hospitalized patients at a tertiary provincial referent medical center in a one-year period.
Material And Methods: In the present retrospective and descriptive cross-sectional study, 438 admitted patients referred for MRI during 2017 were selected using systematic random sampling.
Background: Bromelain enhances anticancer impacts to chemotherapeutic agents. The question as to whether bromelain does promote cytotoxic and proapoptotic effects of cisplatin on human prostatic carcinoma PC3 cell line was investigated.
Materials And Methods: PC3 (human prostatic carcinoma) cells were treated either single or in combination with bromelain and/or cisplatin.
Background: Metacognition and academic self-efficacy are two emerging resources in the process of learning. Basic levels of metacognition and academic self-efficacy may differ and be influenced by demographic and academic factors. This study investigated impacts of demographic and academic factors on metacognition, metacognitive skills, and academic self-efficacy in health sciences students.

The current study investigated the effectiveness of a modified protocol of "student personalized learning" (SPL) (integrating elements of differentiation approach) on metacognitive skills development.
Materials And Methods: A cross-sectional study was conducted among 22 bachelors during the academic period of 2016-2017.
Background: Acute kidney injury (AKI) is a frequent event after cardiac surgery with increased mortality and morbidity. We explored frequency, risk factors, and associated morbidity and mortality of AKI after isolated coronary artery bypass grafting (CABG) surgery at a single institution.
Methods: All consecutive adults undergoing CABG surgery from March 2013 to October 2016 were assessed for development and severity of AKI based on Acute Kidney Injury Network (AKIN) criteria.
Introduction: The European System for Cardiac Operative Risk Evaluation II (EuroSCORE II) is a prediction model which maps 18 predictors to a 30-day post-operative risk of death concentrating on accurate stratification of candidate patients for cardiac surgery.
Objective: The objective of this study was to determine the performance of the EuroSCORE II risk-analysis predictions among patients who underwent heart surgeries in one area of Iran.
Methods: A retrospective cohort study was conducted to collect the required variables for all consecutive patients who underwent heart surgeries at Emam Reza hospital, Northeast Iran between 2014 and 2015.
Direct cannulation of both venae cavae (bicaval venous cannulation) is the gold standard for right atrial isolation in intracavitary surgery, but there has been no consensus about an alternative site. Therefore, we studied an alternative method for bicaval venous drainage in which the left brachiocephalic vein (LBCV) is cannulated instead of the superior vena cava. From 2012 through 2014, we performed routine LBCV cannulation in 150 consecutive patients as part of bicaval venous drainage before right atrial isolation.

By the present retrospective study, we sought to determine the advisability of surgery as well as the anatomical and biomechanical features of flail segment leading to secondary dislocation.
Method: From 1970 to 2000, 127 patients underwent flail segment osteosynthesis.
