Brucella is a facultative intracellular pathogen, and brucellosis is commonest zoonotic disease worldwide. Brucella species, isolated from domestic animals, are important pathogen for humans. Annually, more than 500,000 new cases of brucellosis are reported, and this figure is an underestimate due to extended under-reporting cases in several endemic countries. Brucella has a variety of virulence mechanisms that prevent detection and activation of innate immunity, but protection against intracellular pathogen is represented by cell-mediated immunity. As yet, much research has been performed to develop a safe Brucella vaccine to control the disease in human and animals. Despite the availability of several live attenuated vaccine for animals, currently, no effective human vaccine is available. Moreover, due to the potential use of Brucella in bioterrorism or biowarfare, development of an effective vaccine against brucellosis for human use is necessary. In this paper, we aimed to review and discuss the efforts of researchers to develop vaccines against Brucellosis.

One goal of comparative studies of literature is to search for the human “truth” that has appeared as archetypes in the literature of all nations and all times. In this paper, the author draws an archetypal comparison of romantic love in the French story of "Tristan and Iseult" and the Iranian epic romance "Samak-e-‘Ayyar". It starts with explaining the Jungian concepts of mother and father archetypes, anima and animus, conscious and unconscious, as well as collective conscious and unconscious. Since individuation process in the Jungian psychology has to do with the connection between the conscious and unconscious, the tale romantic love could be seen as individuation process in which each lover seeks to connect to his/her anima (feminine unconscious) and animus (masculine unconscious), based on his/her gender. After providing a synopsis of each story, the author explains the archetypal roles and symbolic meanings of kings, queens, heroes, witches, and princesses in each story using Marie-Louise Von Franz’s methodology for the interpretations of fairy tales. It then compares romantic love in each story by analyzing its characters, functions, and events, and explaining its similarities and differences. Since archetypal literary analysis reveals the attitude, outlook, and behaviors of the people that the myths are originated among them, this comparative study aims to answer to a rather broad question: How is it that in the French story of the 12th century, romantic love ends with death and tragedy; however, in the pre-Islamic Iranian tale, it ends with the :union: of lovers?

The endurance of any type of architecture is contingent upon the study of the characteristics that led to its formation. Two general approaches have been adopted to study and analyze the Iranian architecture. A number of scholars have taken a historical approach, while others have merely considered a genre- based approach. Making use of many historical studies, these scholars have attempted to produce an exacting categorization of Iranian architecture. They focuse on outward form and embellishment to identify and distinguish various classes and sub-classes of architecture in Iran. The third approach, which is outlined in this article, tries to explain such architecture from a conceptual point of view. This essentially involves identifying and analyzing those features that have allowed it to endure. The article shows that there has been a precise and thought- provoking interaction between architects and the intellectual classes that led to the formation of an enduring and transcendent form of architecture in Iran.

Bertolt Brecht wanted the theater to become a forum for dialogue rather than a platform for delusions, and to develop a new concept of theater creativity known as "Westernization" or "APEC Theater" which aims to stimulate the cash circle in the spectator's mind. This concept is based on the idea of "making what is strange" and this turns it into a poetic act. Brecht intended, from this concept, to extract emotion from theatrical production and to distance the viewer from the characters of the play and the actors' departure from their roles, and then the truth becomes easier to understand. Asghar Farhadi is considered one of the most important Iranian film directors, and he is one of the few who owns a style of their own, and The Salesman  is one of his most important films as we in this article seek to show the way this film took in order to find positive and interactive viewers through two main axes: characters and their conversations as well as direction. Here we can see the way the audience is formed. By extrapolating this film with the opinions of Brecht, and the reasons for the influence of the film "Froshendeh" or Salesman, on the audience, it will be analyzed through the concept of divergence and identification. It seems that Farhadi like Brecht uses the same indirect methods, to reach effective and active viewer and forcing the audience to think. But, of course, Farhadi's style does not contradict the audience's identification with the characters of the film, in addition to creating a special and modern type of divergence in his own way through camera movements, decoration, decoupage, film framing, and narrative. Because in the present era with ordinary subjects and a normal treatment of the story, this does not force the viewer to think.
