Multiple Sclerosis (MS) is considered an autoimmune inflammatory disease of the central nervous system. We compared for the first time the adhesiveness of CD4 and CD8 lymphocytes from acute, non-treated patients with the relapsing remitting form of the disease (RRMS) and from healthy donors under physiological conditions. We show that in patients with RRMS CD8, but not CD4, T cells display incr...

Multiple sclerosis (MS) is considered an autoimmune inflammatory disease of the central nervous system. Under physiologic conditions, we compared the adhesiveness of CD4+ and CD8+ lymphocytes from nontreated patients with acute, relapsing-remitting multiple sclerosis (RRMS) and from healthy donors. We show that in patients with RRMS CD8+, but not with RRMS CD4+, T cells display increased rollin...

This study was undertaken to compare the entrance surface dose (ESD) and image quality of adult chest and abdominal X-ray examinations conducted at general practitioner (GP) clinics, and public and private hospitals in Malaysia. The surveyed facilities were randomly selected within a given category (28 GP clinics, 20 public hospitals and 15 private hospitals). Only departmental X-ray units were...

The main purpose of this study was to investigate patient dose in the chest (PA/AP/LAT) and skull (PA/AP/LAT) X-ray examinations, as frequent procedures. The study was performed in eight public hospitals of Khuzestan province, Iran. Patient dosimetry was conducted on 567 standard patient X-ray examinations (males: 61.2%, female: 38.2%). Dosimetry protocol in this study was indirect method, acco...

BACKGROUND Conventional cardiac pacemakers are still often regarded as a contraindication to magnetic resonance imaging (MRI). We conducted this study to support the hypothesis that it is safe to scan patients with cardiac pacemakers in a 1.5 Tesla MRI, if close supervision and monitoring as well as adequate pre- and postscan programming is provided. METHODS We followed up 356 patients (age 6...

Multiple sclerosis (MS) is considered an autoimmune inflammatory disease of the central nervous system. Under physiologic conditions, we compared the adhesiveness of CD4 and CD8 lymphocytes from nontreated patients with acute, relapsing-remitting multiple sclerosis (RRMS) and from healthy donors. We show that in patients with RRMS CD8 , but not with RRMS CD4 , T cells display increased rolling ...

Testing holds an important place in the Iranian test-oriented context where the entrance examinations have serious educational and occupational outcomes. This study aimed to explore the potential washback effects of the General English Language Test of the Ph.D. (GELTP) as part of the Ph.D. University Entrance Examination (PUEE) on the humanities and science students’ perceptions and practices....
