Host genetic factors may predict the outcome and treatment response in hepatitis C virus（HCV）*** of these factors is the single nucleotide polymorphisms of the interleukin 28B（IL28B）*** sought to evaluate the outcome of pegylated interferon and ribavirin therapy in association with IL-28B rs8099917 and rsl2980275 in patients infected with HCV genotype 4.A total of 180 patients with chronic hepatitis C were selected from Egyptians who have received combined therapy with pegylated interferon and ribavirin for 6 months and their response was evaluated after follow-up at 0,6,12,24 and 48 weeks from the beginning of the *** samples were collected from responders and *** DNA was extracted from whole blood and genotyping was carried out by polymerase chain reaction and restriction fragment length polymorphism（PCR-RFLP）.Our results showed that TT genotype of rs8099917 was associated with higher sustained viral response（SVR）rates and G allele represented a risk factor for failure of response（OR=3.7,CI=1.8：7.64）while rs12980275 was not significantly associated with SVR in genotype 4 Egyptian *** determination of 1L-28B SNPs may be useful in enhancing correct prediction of SVR achievement in treating this group of genotype 4 patients.

This paper studies the effects of Natural convection and Thermal radiation on nanofluid over a non-linearly stretching sheet. The governing equation of nonlinear partial differential equations of the flow is transformed to nonlinear ordinary differential equations by using similarity transformation, earlier than being solved numerically through a Rung-Kutta-Fehlberg method with shooting technique. The numerical results have been obtained for The influence of Brownian motion number (Nb), thermophoresis number (Nt), Grashof number (Gr), Lewis number (Le), stretching parameter (n), and thermal radiation parameter (Ra) on the velocity, temperature, and nanoparticles concentration profiles are shown graphically.

Current dependence and stability of the measured resistance value are very important for the accurate measurement of DC standard resistor. In this paper, the volt-ampere （V-I） measurement method has been applied to study the current depend-ence of four different types of standard resistors. Diverse values are obtained through the investigation of their stability at dif-ferent currents. Therefore, the current dependence coefficient （CDC） can be determined for each one of the studied resistors. Research shows CDC depends on the applied current value, the measurement time and the resistor type, as clearly demonstra-ted in this research.

Retrocaval ureter is a very rare congenital malformation. We report a 10 years’ experience in the diagnosis and treatment of retrocaval ureter, a case series of 3 cases in two different countries of the Middle East. This is a retrospective study that included 3 cases of retrocaval ureters in Egypt and Saudi Arabia. Standard open ureteroureteric anastomosis was performed through a flank incision for each case. Patients’ symptoms were re-evaluated after two to four months. Complete recovery from symptoms occurred, and hydroureter and hydronephrosis regressed in all cases. Early diagnosis and treatment are the keys to prevent hydronephrosis and deterioration of renal functions.

Objective: Inflammatory bowel diseases (IBD), including Crohn’s disease and ulcerative colitis (UC), are chronic and recurrent disorders of the gastrointestinal tract with unknown etiology. Considering the adverse effects and incomplete efficacy of currently administered drugs, it is crucial to explore new drugs with more desirable therapeutic profiles. As non-competitive N-methyl-D-aspartate (NMDA) receptor antagonists have shown analgesic and anti-inflammatory properties in vitro and in vivo, this study aims to investigate the role of ketamine, a noncompetitive NMDA receptor antagonist, in acetic acid-induced rat colitis. Methods: Ketamine (10, 50 mg/kg), and dexamethasone (1 mg/kg) were given intraperitoneally 30 min before induction of colitis which was done by instillation of 2 mL of 4% acetic acid (vol/vol). At the 4th day of colitis induction, animals were sacrificed and distal colons were assessed macroscopically and microscopically. Furthermore, the mucosal contents of lipid peroxidation (LPO), reduced glutathione (GSH), nitric oxide (NO) and tumor necrosis factor-α (TNF-α) were assessed. Results: Ketamine (50 mg/kg) and dexamethasone significantly (p α and elevated GSH levels. Conclusion: Our data suggest that ketamine has valuable protective effects in acetic acid colitis and it may be a new therapy target in ulcerative colitis patients, possibly by regulating antioxidants and inflammatory mediators.
