    Abstract
    Objective: Colchicine has been used in recent years as an effective drug for controlling attacks in Behçet’s disease. In the present study, we investigated expression levels of IL1R, IL2R, IL12RB, IL23R, IL17, CXCR3, CXCR10 and IL8 genes in patients with active and inactive Behçet’s disease. We also evaluated how colchicine

    Objective: Colchicine has been used in recent years as an effective drug for controlling attacks in Behçet’s disease. In the present study, we investigated expression levels of IL1R, IL2R, IL12RB, IL23R, IL17, CXCR3, CXCR10 and IL8 genes in patients with active and inactive Behçet’s disease. We also evaluated how colchicine use in patients with active and inactive disease affected these genes and evaluated their role in the etiopathogenesis of the disease. Methods: Thirty-five patients who were diagnosed with Behçet’s disease according to the International Working Group criteria (28 with active disease, 7 inactive) and were taking colchicine were enrolled in the study. Twenty healthy subjects were included as a control group. Expression levels of the IL1R, IL2R, IL12RB, IL23R, IL17, CXCR3 ,CXCR10 and IL8, genes were evaluated. Results: Expression levels of CXCR3 and IL23R were significantly lower in patients with active Behcet's disease when compared with the inactive disease and control groups. However, the differences in CXCR3 and IL23R expression between the inactive Behçet’s patient group and the control group were nonsignificant. Expression levels of the other genes did not differ statistically between the active Behçet’s patients, inactive Behçet’s patients, and control subjects. Conclusion: While the expression levels of the CXCR3 and IL23R genes in active Behçet’s patients were statistically lower than controls, there was no statistical difference between active and inactive Behçet’s patients or controls in terms of IL1R, IL2R, IL17, IL12RB, CXCR10 and IL8, gene expression levels. This study may form the basis for further studies to determine the molecular mechanism of colchicine in the treatment of Behçet's disease.Full article

    The aim of the study was to evaluate the relationship between different yogurt packages, drinking methods, and residues and the countermeasures. We chose 7 of the most common yogurt packages in the Chinese market, calculated the amount of residue left after yogurt consumption, compared the amount of yogurt residue left after using different methods of consumption from different types of packages, and conducted surveys in supermarkets, schools and other public places. After yogurt consumption, there are always residues left, and different packages and different drinking methods lead to different amounts of residues. The selection of yogurt package and the adoption of a good drinking method can clearly reduce the amount of residue. The solution that we suggest is to provide proper and clearly visible drinking instructions on the package to significantly reduce the amount of residue and wasted materials.Full article

    Background: Anemia is the most frequent hematologic abnormality of HIV disease and one of the most common manifestations of nutritional deficiency disorders in the world. In sub-Saharan Africa, about 70% of the world’s people living with HIV/AIDS, where the prevalence of anemia is higher than in developed countries. The aim of this study was to determine the prevalence and factors associated with anemia among people living with HIV at Dodoma regional hospital during 2013-2014. Methodology: A retrospective cross-section study conducted among PLWHIV at Dodoma Regional Hospital between 2015 and 2016. A total of 869 PLWHIV were enrolled. Data extraction sheet were used to collect Socio- demographics, immune-hematological data and ARV status from existing patient’s files (CTC 2 card). Double entry of data in Microsoft excel were done and transferred for analyzing using SPSS v.16. Results: Majority of them were females 648(74.6%)and 508(58.2%) were between 19-45years with mean age of 38.84(±14.09). 824(94. 8%) were on ARV; where 640(73.6%) are from urban. The overall prevalence of anaemia among PLHIV was 59.5% of which 56.6% of these were on ARV, and 2.9% were not on ARV. Age, sex and CD4+ counts < 200cell/µl were among factors associated with anemia among PLWHIV. Conclusion: Moderate anaemia was common in the study population. Screening and management of anemia along with the proper use Anti-retroviral therapy may decrease risk of anemia and the effect ARV on red blood cells. Haemoglobin measurements should be taken before initiation of ARV and routinely followed among ARV users.Full article

    Polysaccharides are known to have interesting biological activities. To date polysaccharides extracted from Tunisian seaweed have not been fully studied. In this paper we tried to isolate sodium alginate from two brown algae and evaluate their biological activities. Two brown seaweeds Dictyopteris membranaceae and Padina pavonica were treated with selective solvents to extract sodium alginate. Analyses were performed to determine their IR spectra, uronic acid’s content and biological properties (antioxidant and gastroprotective activities). Results showed that sodium alginate extracted from D. membranaceae contained 65% of uronic acid while this extracted from P. pavonica contained only 9% of uronic acid. These polysaccharides showed also variation in the structure and the activities. Sodium alginate extracted from D. membranaceae had the highest antioxidant activity with ED50 of 20µg/ml in the DPPH test. Additionally, this polysaccharide had the most important gastroprotective activity with a percent of 97% at dose 50mg/kg. Our finding suggested that sodium alginates extracted from D. membranaceae and P. pavonica could be used as a natural source of antioxidant and gastroprotective agents.Full article

    The kinetics and mechanism of oxidation of methyl cellulose (MC) polysaccharide by hexacholroiridate (IV) in aqueous perchlorate solutions at a constant ionic strength of 0.1 mole dm-3 has been investigated, spectrophotometrically. The experimental results showed first-order dependence in [IrCl6]2- and fractional first-order kinetics with respect to the MC concentration. The reaction rate was found to increase with decreasing the [H+]. A kinetic evidence for formation of 1:1 intermediate complex was revealed. The reaction kinetics seems to be of considerable complexity where one chloride ion from hexacholoiridate (IV) oxidant may act as a bridging ligand between the oxidant and the substrate within the formed intermediate complex. However the added chloride ions and oxidation products were found to have negligible effects on the reaction rate, the added acrylonitrile indicated the intervention of free-radical mechanism during the oxidation process. The kinetic parameters have been evaluated and a tentative reaction mechanism consistent with the kinetic results is discussed.Full article
