Abstract: The burden of under-five mortality remains unevenly distributed. About 80 percent of under-five deaths occur in two regions, sub-Saharan Africa and South Asia. Ethiopia is among the six countries that account for half of the global under-five deaths. The aim of this study was to identify the significant socio-economic and demographic factors influencing under-five child mortality and evaluate the variation among the regional states of Ethiopia. In this study, the 2000, 2005, 2011 and 2016 EDHS data were used to describe the trend of under-five mortality in Ethiopia. The 2016 EDHS data have been used to analyze determinants and variation of under-five mortality by background characteristics. Single-level logistic regression and multilevel logistic regression models were used to identify the major risk factors of under-five mortality and regional variations in under-five child mortality in Ethiopia using the 2016 EDHS data. The results from single-level and multilevel logistic regression analyses showed that Sex of a child, Age of a child in month, Birth type, Birth order number, Number of Household size, Breastfeeding status, Educational level of mother’s, Place of residence and type of toilet facility had significant effects on under-five child mortality and there is variation of under-five child mortality from region to region. Conversely, preceding birth interval, wealth index Household, Source of drinking water and place of delivery were found insignificant. The results revealed variation of under-five child mortality from region to region. The multilevel logistic regression analysis result showed that the effects of breastfeeding varied across regions whereas the effects of other covariates on under-five child mortality remained fixed across regions.

Abstract: Farm animals’ meat contributes significantly to the daily protein intake of many individuals but can also be a source of foodborne illnesses especially under the conditions in which animals are handled, slaughtered, transported and sold. The emergence and re-emergence of diseases due to pathogenic bacteria are the key issue of the new pattern of food trades. A total of twenty-one samples (VIS, FSA, STS, MSA, URS, UDS, and PES) were collected from farm animals from Rugga settlement of Birnin Kebbi. Some of the samples were collected using sterile swab stick while urine and stool samples were collected in sterile containers and were taken immediately to Microbiology Laboratory Waziri Umaru federal Polytechnic. The samples were bacteriologically analyzed and the isolates were identified using biochemical tests such as (indole, coagulase, catalase, urease, gluctose, lactose, maltose, motility, Voges Proskauer and methyl red). Fourteen bacterial species were isolated and identified as pathogens from the sheep samples. They are Gram positive bacteria such as Streptococcus agalactiae and Staphylococcus aureus as well as Gram negative bacteria such as Escherichia coli and Shigella sp and Salmonella sp. The isolates were identified based on their reaction to biochemical tests. The findings revealed that sheep are potential vehicles for transmitting pathogenic bacteria and the presence of these microorganisms may lead to poisoning and can as well claim the live of the sheep from which they were isolated.

Abstract: Investigating the population dynamic of important cotton pests on new cotton varieties is important. Cotton cultivars have important pests such as thrips, aphids, whitefly and bollworm. Considering the premature cultivars with proper yield for second cultivation in cotton-growing Golestan province at the north of Iran, this study seems necessary. This genotypes was cultivated with 9 treatments in 4 replicates. A completely randomized block design was carried out in Hashem Abad research station in a spray-free plot with the dimensions of 30 × 80 cm in 2018-2019 years. According to the results of this study, analysis of variance of two years showed that the yield of N2G80 with 1538 g in the plot with 41.7% lint percentage had the highest yield, and M13 with 685 g in the plot and 35.8% lint percentage in the lowest yield they had. The infestation rate of the genotypes tested in the population of green aphid of cotton in K880-2 and Golestan® cultivars was 48.88 and 40.31 in aphid with the highest density, and the SKT-133 and TBL-60 genotype respectively with 27.15 and 29.11 aphids per leaf had the least infestation. The amount of infestation of the genotypes tested to the population of whitefly cotton on the N2G80 and TBL-60 genotype was 90.76 and 68.86 whitefly in the leaf with the highest infestation and N2G80 and TBL-60 genotype respectively with 40.05 and 75.51 white fly in leaf were the least infested. Correlation coefficient between traits was equal to 0.55. The number of bolls per plant was not correlated with other traits including boll weight, lint percentage, aphid and white fly.

Abstract: Background and Objectives: Atherosclerosis is the most common type of arteriosclerotic vascular disease. It is characterized by accumulation of lipids, hemorrhage and thrombosis, and gradual degeneration and calcification of the middle layer of the artery. It is very harmful to human body. To diagnose atherosclerosis at an early stage, a new animal model of abdominal aorta in New Zealand rabbits was established using high-fat diet with balloon injury to simulate the natural process of human disease. Methods: In our study, the high-fat diet and balloon strain technique were used to establish this model, CT imaging and pathological examination were used to prove the successful establishment of the model. Results: The results demonstrated that two weeks after high-fat feeding, the rabbits’ survival rate was 100% and their body weights gradually increased over time. Compared with basic levels, all atherosclerotic indexes (AI) were higher than 4. Pathological observation and CT imaging showed that the location of vascular injuries was stenosis and the lesions were consistent with the basic characteristics of atherosclerosis. Conclusions: The above results indicated that under our experimental conditions, the rabbits’ model of abdominal aorta atherosclerosis (AS) could be successfully reproduced. Compared with previous atherosclerosis models, it has the characteristics of a short modeling time and method simplicity. More importantly, it can be used as a follow-up model of atherosclerosis early diagnosis.
