Cross-Reaction between the Crude Hydatid Cyst Fluid Antigens of Human and Animals Origin in Response to Human IgG Class and Subclasses

The current work aimed to evaluate the cross-reactivity of human immune sera against crude hydatid fluid antigens of sheep, human, mouse, cattle, as well as B fraction of cystic fluid antigen. 30 balb/c mice were infected with sheep hydatid cyct fluid antigen containing protoscolex after the viability of these protoscolices was assessed. ANOVA was used to test the difference of themean of optical density (OD) values among case and control groups. The highest human IgG class antibody was against antigen B (0.93) and the lowest against cattle HCF antigen (0.32). The differences between responses to these antigens were statistically significant (P < 0.001). The sensitivity and specificity of ELISA test used for evaluating the responses of human total IgG to different hydatid cyst fluid (HCF) antigens among the case and control groups were 100 and 95.8%, respectively. Cross-reaction of human IgG class and subclasses responses was found almost for all the antigens with the best reaction against human and cattle (HCF) antigens and antigen B using a ratio of mean OD value to each antigen divided by the cut-off point value for the same antigen. Human sera showed a considerable cross-reactivity against all antigens by using ELISA

Determine the Degree of Acceptance Of E-Learning Readiness in the Persian Gulf University

E-learning is not restricted by time or place and can provide teachers with a learning environment that is flexible and convenient, enabling them to efficiently learn, quickly develop their professional expertise, and advance professionally. The overall objective of this study was to investigate the possibility of implementation of E-Learning system in the Persian Gulf University of Bushehr. Statistical population of this study included students at 90-91 semester in Bushehr University. Sample size was 360. The method for selection of statistical sample size was stratified random sampling method. To confirm the validity of questionnaire content validity was used. Therefore, the opinions of teachers and experts were obtained. The reliability of the questionnaire was measured by Cranach’s alpha. The coefficients of different sections of questionnaire are between 0/90 to 0/97. For data analysis, descriptive statistics and inferential statistics (ANOVA one-way and t-test) was used. The results showed that the students of Persian Gulf University have relative readiness to participate in E-learning. In addition, analytical data indicated that the faculty of Literature and Humanity Science and Engineering had the highest score, but the read in ess to participate ine-learning between these faculties with others has no meaningful difference
