AbstractProblem statement: There is a similarity between images of the sacrificing of the sacred bull in Mitra’s religion painted in the ancient era and the pictures of Rostam’s battle with the white demon in the images of coffee houses in visual and pictorial characteristics that can be recognized by studying them. This similarity and formal connection is a suitable case for matching and checking the type of composition and the visual and image characteristics of these paintings. Considering that the image of the battle between Rostam and the white demon has some similarities with the scene of the sacrificing bull by Mitra-Mehr, both battles took place in the cave, and in general, the cave was sacred and had an important place in different religions.Research objective: By achieving the type of relationships and effects in the elements used in the composition system, such as the type of sitting and standing of figures, guiding lines, and other visual elements, the comparison of works with a qualitative nature has been done.Research method: The type of research is fundamental-theoretical and the research method is descriptive-analytical. Data including the author’s archive were collected the library research method.Conclusion: The coffee house painters have drawn (the scene of the killing of the white demon by Rostam) according to the previous patterns in the past painters’ works. These effects are evident in the triangular composition system, the sitting position of the figures on the defeated creature (bull and white demon), and the presence of daggers in the hands of Mitra and Rostam. One of the common features of the paintings is the visual representation of the manpower of good and evil. Although the belief in the existence of light and darkness is rooted in the ancient beliefs of Iranians, it seems that the viewpoint of the painters and their attention to good and evil is taken from the Shahnameh.

The coronavirus storm, first reported more than a year ago, has overshadowed all societies' parts and become a chal-lenge to all of the world's health systems 1. Extremely high contagiousness, significant mortality rates, and the lack of a de-finitive cure have prioritized overcoming this outbreak. In this regard, studies related to coronavirus and especially its clini-cal studies, became a priority for researchers and decision-makers at the request of governments and the people, as well as by the logic. The superiority of an emergency is not a wrong decision. Still, the problem arose when other research areas were neglected, and their budgets were reduced by decision-makers, resulting in damage to the research and researchers in other fields 2, 3. The clinical studies currently being conducted on coronavirus disease 2019 (COVID-19) are due to previous studies in the basic sciences that have provided the background. Obviously, without scientists' tasks over the years and the allocation of research funds to the fields of genetics, biochemistry, immunology, etc., studies and advances would not be possible today

Seven healthy and sexually adult bulls were slaughtered and their reproductive system was isolated. Different tissues including: testes, epididymis, vas deferan, ampulla, accessory sex glands (seminal vesicle, prostate and bulb urethra), muscular and mucosal layer of pelvic and penile urethra were carefully dissected. Total soluble protein and arginase specific activity (ASA) were measured by Lowry and modified paranitrophenylglyoxal (PNPG) method, respectively. The results indicate that the highest arginase specific activity (51.28±8.79 x10-3 IU/mg of protein) is present in muscle of pelvic part of urethra. Based on ASA, bulls reproductive system was categorized in three tissue groups: high, medium and low. Muscular layer of penile urethra with the highest ASA level (> 50 X10-3IU/mg tissue protein) is in the 1st group, Testes, bulbourethral gland and mucosal layer of penile urethra (30-40 X10-3 IU/mg tissue protein) are in the2nd group and the rest parts (<25 X10-3IU/mg protein) arein3rd group. Significant differences observed between classified tissues (p<0.05). The present study indicates that ASA is present at different levels in all parts of bull reproductive system. This condition may be related to different rate of cell proliferation and differentiation or some other unknown physiological and biochemical activities of the enzyme in this system.

The related Values of Iran-Iraq war (Holy Defense) are categorized in social values within our Islamic society. We can now assume them as national and civil values in our society. Regarding to their exciting and profound contents, these values can be discussed as a new cultural discourse. Based on above mentioned causes, the present essay has been studied sacrificing scenes in 166 Iranian war movies for the years 1981 to 2007 with content analysis method. Emergence of sacrificing scene and the way it changed was analyzed in a sample of 62 movies using quantitative content analysis technique. Results indicates that the scenes were mostly individual and masculine with religious named actors rather than being collective and feminine with non-religious named actors. Most of sacrificing actions happened in risky areas exposed to enemy forces. Sacrificing scenes in post war movies somehow were more than the movies directed during the war. The way these scenes happened was also different to some extents.

Collected semen with a good quality and quantity is essential for a bull for selected semen collection and preservation. This survey was carried out on a Friesian Holstein bull, kept in Northwestern breeding center of Iran. Although the bull had normal libido, the semen produced was reported to be azoospermic. Clinical examinations proved no testicular abnormality but the scrotal circumference was measured 27 centimetres which is less than the normal size of this breed (at least 30 centimetres). In histopathological studies, there was a decrease in semeniferous tubule's epithelium (sertoli and gonadal cells), Beside intratubules focal calcifications, fonnation of new connective tissue and vascularization was observed. All of these signs demonstrate an extensive degeneration in both testes.

This is a report of a penile fibrosarcoma in a two-year-old crossbred Holstein bull. The ulcerated tumor mass with dimensions of 7 × 9 × 6.5 cm, was enveloped the glans and body of the penis. It had a white-gray color at cross section appearance. There was no metastatic evidence of regional lymph node enlargement. Histopathologically, elongated spindle-shaped cells arranged densely in the interwoven pattern had a low rate of mitosis with oddly-shaped nuclei and pleomorphism. Immunohistochemically, the neoplastic cells were positive for vimentin and S100, but negative for α-smooth muscle actin, desmin, C-KIT and GFAP.

What roles do sacrificing behaviors play in marital life? Does perception of equity influence the association between sacrificing behaviors and marital intimacy? To examine how sacrificing behaviors, perception of equity, and marital intimacy are connected, we had a sample of 140 married couples (140 females and 140 males) complete three measures— the Measure of Equity Perception (MEP), the Perception of Sacrifice Measure (PSM), and the Intimacy Scale (IS). The results showed a significant relationship between equity perception, sacrificing behaviors and marital intimacy. The results also indicated that the relation of sacrificing behaviors with marital intimacy was higher for women with higher equity perception than for women with lower equity perception, whereas this interaction did not occur for men. The implications of the interaction and the gender difference, as well as the importance of enhancing sacrificing behaviors and equity perceptions, are discussed.
