Abstract
The main concern in fish transportation is minimizing stress during transportation. In this study, the effect of zeolite and clove essence in terms of transportation on survival and stress rainbow trout was investigated. 4 treatments (each treatment included 3 replicate) including control treatment, clove essence (25 mg/l), zeolite (14g/l) and clove essence (25mg/l) + (14g/l) were considered. 156 fish (with average weight 80 ± 4.4 g) were randomly distributed with a 130 kg/m3 density. At time zero, 6, 12 and 18 hours after starting transportation, survival rates, cortisol and glucose levels (as indicators of stress) were measured and analyzed. In the end, results showed a significant difference in the survival rates that control treatment had the lowest survival rates (P

Abstract
Aims: Helicobacter pylori is a pathogen that can be colonized in the stomach. Most laboratories only use IgG and not IgA antibody to diagnose infection. The aim of this study was to compare both IgG and IgA-antibodies level for the detection H. pylori.
Materials & Methods: The presence of IgG and IgA antibodies in the sera of the 517 patients suspected to H. pylori infection was evaluated by Enzyme-Linked Immunoadsordent Assays (ELISA) method.
Findings: The positive cases of infection on the basis of IgG and IgA titers were 68% and 27%, respectively. Also, 7% of the patients with IgG negative were IgA positive.
Conclusion: The comparison of antibody responses in our patients indicate that the sensitivity of IgA level is lower than IgG ELISA and both antibody titers must be evaluated for the identification of infection. In some cases, patients with IgG negative may have IgA positive assays; therefore, in the serological diagnostic process and without endoscopy, IgG results in association with IgA against H. pylori will be completed.

Abstract
Cyberspace has provided the ground for the emergence of a new generation of games, in the namely of virtual games, which are beyond the games and entertainment. Although the computer games, as a part of entertainment industry, are basically considered with cultural and economic approaches, what makes such games an attractive topic for law, is the possibility of buying and selling virtual goods and items within the context of games.In-game transactions associated with some challenges with the legal status of such transactions are the most important ones. In the meantime, what makes the validity of online transactions a challenging topic refers to the doubt on the vital elements of subject-matter of contract. Since everything occurs in a virtual environment, so the objects of transactions are intangible, and in fact, do not exist. Moreover, what purchased and sold are just beneficial and valuable for the game players through the game so that they have no function and benefit out of the game. This paper tries to have a legal analysis on virtual goods and items from the point of essential conditions for the validity of the object of transactions.
