Hepatitis B and Hepatitis C viruses are the major health problem in the worldwide. In the Middle East, the prevalence of HBV in general population with the chronic infectionsis 2-5%,whereas the prevalence of HCV is about 1% in Arabian Gulf countries. World Health Organization (WHO) revealed that the risks of HBV and HCV transmissionas well as human immunodeficiency virus (HIV) through the transfusion of contaminated blood and blood products is high, because of the fragility of health services in these countries. Several viral diseases are transportby different modes like bloodtransfusion, sexual contact, and unsafe injections. The mostcommon blood-transmitted viruses are hepatitis B virus(HBV), hepatitis C virus (HCV) and humanimmunodeficiency virus (HIV);which cause fatal and chronic disorders. The prevalence ofthese viruses varies in Asia and developing countries depending on nationality, geography and lifestyle, sex, race, and educational levels. For all these previous causes, thisstudydesigned to know the seroprevalenceof HBV, HCV and human retroviruses(HIV-1, 2) among inpatients and outpatients of Balad General Hospital in Saladin governorate in Iraq. The study conducted in Balad General Hospital. Subjects with hepatitis C, B viruses, and HIV recorded from January2017 to December 2017. The age of patients ranged from 6 to 70 years; and the total number of tested serum samples was 32,942 serum samples. The highest percentage of HBVprevalence was in July by using ELISA technique (11.1%) for outpatients followed by 15.40% for outpatients in May by using anti-HBV strip.While the highest percentage of HCV prevalence was recorded in July by using ELISA technique (11.73%) for outpatients followed by 14.76% for outpatients in May by using anti-HCV strip. The percentage of patients infected with HBV in both sexes (females and males) was higher than the percentage of patients infected with HCV (1.80%vs.0.57%, respectively). Also, the present study indicated the seroprevalence of HBV (anti-HBV) was 38.27% for female and 41.02% for male with age range 21-30 years, and this significantly higher than in HCV which thepercentage of the seropositive cases were 37.03% in female and 39.13% in male with age range 41-50 years.Therewere no significant differences betweenthe seroprevalences of eachof anti-HCV Ab,anti-HBV Ab and HBsAg,and only 2 cases (0.03%) were seropositive for HIV-1, 2. Although, the HBV and HCV in Iraq are a major problem for the community and viral infectious diseases;the current study revealed that Iraq has a low prevalence for HBsAg, HBV, HCV and HIV.
ABSTRACT:
Microencapsulation is used to modify and retard drug release as well as to overcome the unpleasant effect
(gastrointestinal disturbances) which are associated with repeated and overdose of ibuprofen per day.
So that, a newly developed method of microencapsulation was utilized (a modified organic method) through a
modification of aqueous colloidal polymer dispersion method using ethylcellulose and sodium alginate coating materials to
prepare a sustained release ibuprofen microcapsules.
The effect of core : wall ratio on the percent yield and encapsulation efficiency of prepared microcapsules was low, whereas
, the release of drug from prepared microcapsules was affected by core: wall ratio ,proportion of coa
We study the physics of flow due to the interaction between a viscous dipole and boundaries that permit slip. This includes partial and free slip, and interactions near corners. The problem is investigated by using a two relaxation time lattice Boltzmann equation with moment-based boundary conditions. Navier-slip conditions, which involve gradients of the velocity, are formulated and applied locally. The implementation of free-slip conditions with the moment-based approach is discussed. Collision angles of 0°, 30°, and 45° are investigated. Stable simulations are shown for Reynolds numbers between 625 and 10 000 and various slip lengths. Vorticity generation on the wall is shown to be affected by slip length, angle of incidence,

Show MoreIn this study used three methods such as Williamson-hall, size-strain Plot, and Halder-Wagner to analysis x-ray diffraction lines to determine the crystallite size and the lattice strain of the nickel oxide nanoparticles and then compare the results of these methods with two other methods. The results were calculated for each of these methods to the crystallite size are (0.42554) nm, (1.04462) nm, and (3.60880) nm, and lattice strain are (0.56603), (1.11978), and (0.64606) respectively were compared with the result of Scherrer method (0.29598) nm,(0.34245),and the Modified Scherrer (0.97497). The difference in calculated results Observed for each of these methods in this study.
In current article an easy and selective method is proposed for spectrophotometric estimation of metoclopramide (MCP) in pharmaceutical preparations using cloud point extraction (CPE) procedure. The method involved reaction between MCP with 1-Naphthol in alkali conditions using Triton X-114 to form a stable dark purple dye. The Beer’s law limit in the range 0.34-9 μg mL-1 of MCP with r =0.9959 (n=3) after optimization. The relative standard deviation (RSD) and percentage recoveries were 0.89 %, and (96.99–104.11%) respectively. As well, using surfactant cloud point extraction as a method to extract MCP was reinforced the extinction coefficient(ε) to 1.7333×105L/mol.cm in surfactant-rich phase. The small volume of organi
