This study was conducted to investigate the effect of storage conditions and time of olive oil on its quality characteristics. For this purpose, the samples were placed in Refrigerator Temperature(+4 Co) and Ambient temperature(25±2 Co) and were qualitatively tested in 3 storage time(first day, 1 month and 2 months). The results showed that storage conditions and duration were effective on all parameters. The acidity of extra virgin and virgin olive oil increased significantly during storage under Ambient temperature for two months (12 and 13.8% of oleic acid, respectively), but no significant difference was observed in the temperature of the refrigerator for two months in any of the oils. Extra virgin olive oil also showed a significant increase in peroxide index (16.2 and 18.3 mEq / kg, respectively) during two months of storage under Ambient temperature, but no significant increase was observed in refrigerated dermis in any of the periods. Also, the interaction effect of Ambient temperature and storage time on the extinction coefficients (K268 and K232) of virgin and extra virgin olive oils was significant and with increasing storage time, the extinction coefficients were increased, but the extinction coefficients of oils stored in the refrigerator even after two months Equivalent to the extinction coefficient of oil stored in Ambient temperature remained on the first day. Therefore, refrigeration seems to be a better option to maintain the quality properties of extra virgin and virgin olive oil during the storage period. [ABSTRACT FROM AUTHOR]

Mudskippers are members of the Oxudercidae family and are amphibious fishes that are able to spend long periods out of water. In the present study, Boleophthalmus dussumieri was sampled from Petroshimi and Jafari stations. In order to perform histological studies, the samples (3 males and females from each station) were anesthetized and fixed in Boyne's fixative solution in accordance with biological ethical principles. Then, tissue sectioning and H&E staining were done. Observations by light microscope showed that the epidermis consists of a corresponding epithelium consisting of three cell layers. The dermis of the skin consists of thick collagen fibers and many blood capillaries. In some areas, protrusions from the dermis enter the epidermis, which are called dermal protrusions. There was a significant difference in the thickness of the epidermis layer in males and females. It was 87.97 microns in females and 74.32 microns in males. Based on the amphibian way of life of slugs, in species that are more hydrophilic, the upper and middle parts of the body, which are often exposed to air, have smaller amounts of diffusion distance. Therefore, it can be expected that air absorption through the skin in B. dussumieri takes place more in the upper part of the body than in the lower part or appendages. [ABSTRACT FROM AUTHOR]

Background: Vitiligo is a skin disease charachterized with loss of skin pigmentation and the lack of melanocytes in the epidermis. Its prevalence is estimated as 1-2% of the world population. The cause of this disease is not clear, but the immunologic etiology is strongly suggested due to coincidence of other autoimmune diseases such as thyroid disorders. Thyroid screening tests are not considered as routine tests for vitiligo patients. This study was designed to further study of thyroid function in vitiligo patients. Methods: 63 patients with vitiligo and 63 non-vitiligo from the patients referred to Dr Shariati Hospital and Skin Disease and Leishmaniasis Research Center(SDLRC) were studied. Thyroid function tests tests including TSH, T3, T4, and thyroid antibodies(anti TPO and anti Tg ) were investigated. Data was analyzed by Chi square and Fisher's exact test using SPSS 18. Findings: Frequency of TSH, T4 in both groups were examined and no significant difference between the two groups did not exist(P= 0.09 and P= 0.11). In terms of distribution of T3, Anti-TPO and Anti- Tg between the two groups, significant differences between There were two groups (P= 0.001, P= 0.04 and P= 0.07 respectively). Conclusion: Based n the results of this study there was no correlation between vitiligo and clinical disorders of thyroid. However doing T3,AntiTPO,AntiTg tests is warranted in vitilgo patients for advance diagnosis of any thrroiddisfunction and prevemt their complications. [ABSTRACT FROM AUTHOR]
