The convergence of communications and information technology within education, as well as more widely, means that concepts developed within ITS & AIED are now applicable to a wider range of wired, and more interestingly 'wireless', technologies. Interactive TV, supported by broadband broadcasting, offers interesting possibilities for education. The use of TV (and radio) in education has a long ...

this article elaborates on the experience of higher medical education evaluation in iran. although institutional evaluation in iran started in about a decade ago, recent policies of the government to increase quality of higher medical education have contributed to a special effort in designing and implementing evaluation mechanisms in university systems in iran. among these a process of interna...

conclusions endocarditis is an important disease with a high mortality rate if not treated appropriately. therefore, these patients need more attention. in echocardiography, vegetation and complications of ie such as abscess and paravalvular leakage can be detected. results we studied 35 patients, 45% male and 55% female with a mean age of 56.36 ± 12.44 years. fever (80%) and chills (65.7%) wer...

Background Our recent findings have shown that the rat testis is subjected to significant oxidative stress during the early phase of diabetes induced by Streptozotocin (STZ). In the present study, we have investigated whether oral supplementation of β-carotene (BC) to pubertal rats would provide protection against diabetes associated oxidative stress in testis and liver. MaterialsAndMethods Mal...

introduction: vestibular evoked myogenic potential (vemp) has recently been broadly studied in vestibular disorders. as it is evoked by loud sound stimulation, even mild conductive hearing loss may affect vemp results. bone-conducted (bc) stimulus is an alternative stimulation for evoking this response. this study aims to assess the characteristics of bc-vemp in different groups of patients.   ...

objective(s):emap-like protein 5 (eml5) is a new echinoderm microtubule-associated protein that is expressed in the central nervous system. the aim of this study was to investigate the expression profile of eml5 in the anterior temporal neocortex of patients presenting with intractable epilepsy (ie). materials and methods:western blot assays were performed to determine eml5 expression in 36 sur...

The association of heat-stable enterotoxin (STa) produced by enterotoxigenic Escherichia coli 431 with isolated rat intestinal epithelial cells and brush border membranes was characterized. Specific binding of strain 431 125I-STa to a single class of specific high-affinity receptors was saturable and temperature dependent and reached a maximum between 5 and 10 min. A 1,000-fold excess of unlabe...
