Expression Levels of lncRNAs in the Patients with the Renal Transplant Rejection.

PURPOSE: Long non-coding RNAs (lncRNAs) include a vast portion of human transcripts. They exert regulatory roles in immune responses and participate in diverse biological functions. Recent studies indicated dysregulation of lncRNAs in the process of transplant rejection. In the current study, we aimed at identification of the expression of five lncRNAs (OIP5-AS1, FAS-AS1, TUG1, NEAT1 and PANDAR) in association with the process of transplant rejection. MATERIAL AND METHODS: We assessed expression of these lncRNAs in the peripheral blood of 61 kidney transplant receivers including 29 transplant rejected patients and 32 transplant non-rejected patients using real time PCR technique. RESULTS: Expression of FAS-AS1 was significantly higher in rejected group compared to non-rejected group in males, however, differences between case and control groups were insignificant among females. For other lncRNAs no significant differences were detected between two study groups. Quantile regression model showed that patients' gender was an important parameter in determination of FAS-AS1 expression (Beta=-9.46, t=-2.82, P=0.007) but not for other lncRNAs expressions. Significant pairwise correlations were detected between expression levels of lncRNAs in a disease related manner. CONCLUSION: Based on the higher expression of FAS-AS1 in patients with transplant rejection, this lncRNA might be associated with the pathogenesis of renal transplant rejection.

Impact of climate variability on the occurrence of cutaneous leishmaniasis in Khuzestan Province, southwestern Iran.

Leishmaniasis, one of the most important parasitic diseases worldwide, is frequently cited with respect to health risks related to climate change. The current variability of the climate may have different impacts on the transmission of cutaneous leishmaniasis (CL) depending on the various Leishmania species. The number and distribution of CL cases in Khuzestan Province, Southwestern Iran was analysed over the 2010-2014 period with regard to temperature, humidity, rainfall, sunshine hours, evaporation and wind-related climate issues. During the study period, there were 4672 recorded clinical cases of CL, the incidence of which was found to fall into three types of areas, such as high, intermediate and low-level endemic areas. Compared to the intermediate and low-endemic areas, the hyper-endemic areas showed significantly variable meteorological data with regard to rainy days, maximum/minimum temperature and humidity. Decreased temperatures in the eastern part of this province were found to promote the disease towards its centre. We conclude that the meteorological variables and incidence data of CL indicate that the number of rainy days, maximum and minimum temperatures and relative humidity are significant variables that can predict CL incidence. Indeed, the substantial climatic variability occurring during the recent 5-year period (2010-2014) in Khuzestan Province could be the main reason for the change in epidemiology and transmission of CL.

Growth performance parameters, bone calcification and immune response of in ovo injection of 25-hydroxycholecalciferol and vitamin K3 in male ross 308 broilers.

This experiment aimed to evaluate the effects of in ovo injection of 25-hydroxycholecalciferol (25-OH-D3) and Vitamin K3 on growth performance, bone calcification and immune system responses in male Ross 308 broilers. Twelve treatment groups with a total number of 768 experimental hatching eggs, four replications and 16 eggs in each replication were selected to form a completely randomized design of factorial arrangement. Treatments included: (1) distilled water, (2) 0.4 µg D3, (3) 0.4 µg D3 + 2 µg K3, (4) 0.4 µg D3 + 6 µg K3, (5) 0.6 µg D3, (6) 0.6 µg D3 + 2 µg K3, (7) 0.6 µg D3 + 6 µg K3, (8) 0.8 µg D3, (9) 0.8 µg D3 + 2 µg K3, (10) 0.8 µg D3 + 6 µg K3, (11) 2 µg K3 and (12) 6 µg K3. Eggs were transferred to corresponding hatching baskets on the 18th day of incubation and received 0.5 ml of experimental solutions specific to each treatment. The results of our experiments showed that Treatment No. 4 ranked the best out of those administered; holding the highest level of weight gain, feed intake during the breeding period (grower and finisher), bone calcium and phosphorus concentration, and tibia fractural force, (p < 0.05). Treatment No. 4 also showed a significant increase in antibody titer against the SRBC. Maximum stimulation to PHA injection also belonged to this treatment. In contrast, treatment No. 1 held the greatest alkaline phosphates amount (p < 0.05). No improvements were observed in calcium egg shells compared to the control group. Our data implies that appropriate levels of Vitamins D3 and K3 in ovo injection has beneficial effects on growth performance, immune system and bone development.

Control of Cutaneous Leishmaniasis Using Geographic Information Systems from 2010 to 2014 in Khuzestan Province, Iran.

BACKGROUND: Cutaneous leishmanisis (CL) is found worldwide and is considered to be endemic in 88 countries such as Iran. Geographic information system (GIS) is a method that can create, archive, analyze traditional map and place data of the disease distribution. The aim of this study was to produce distributional maps of CL over five years and evaluate the role of GIS in control of CL in Khuzestan province where an endemic area of CL in Iran is. METHODS: CL epidemiological data on the District and village levels for the period 2010-2013 were provided as census by health surveillance system in all counties and in control diseases center (CDC) of Khuzestan province. After collection of CL data, the collected data of CL from 2010 to 2013 were analyzed using GIS. The collected data of CL from 2010 to 2013 was analyzed using GIS. The endemic areas of CL during 2010-2013 were recognized using GIS maps and the control programs of CL were done in these regions based on epidemiological situation and the stratification of risk areas. RESULTS: During the study period, there were 4672 recorded cases of clinical cases of CL by Khuzestan Health Center. Data of GIS referring to CL patients showed that center and eastern districts of Khuzestan had a significant number of cases. In 2014 that control program was done, ten distinct of Khuzestan Province didn't show any cases of the disease. CONCLUSION: In conclusion, analyses of data distributed in the geographic spaces are increasingly appreciated in leishmaniasis control management. GIS tools promoted greater efficiency in making decisions and planning activities in the control of vector born disease such as leishmaniasis.
