All participating patients gave their written,informed consent. After inclusion, patients with acute symptoms of hemorrhoids were centrally randomized to receive, as outpatients, by the rectal route, suppositories of rsK 200000 IU of one unit every 8 h(first 3 units)and afterwards every 12 h until 8 administrations were completed(schedule A), one unit every 8 h until 6 units were completed(schedule B), or 25 mg hydrocortisone acetate once every 8 h up to a maximum of 24 administrations. Evaluations were performed at 3, 5,and 10 d post-inclusion. The main end-point was the 5thday response(disappearance of pain and bleeding, and≥ 70% reduction of the lesion size). Time to response and need for thrombectomy were secondary efficacy variables. Adverse events were also ***: Groups were homogeneous with regards to demographic and baseline characteristics.

The present study was done using two concentrations of the photosensitizer Hematoporphyrin coated Gold Nanoparticles (HpdGNP3) (5x10–6 , 5x10–5 mole/dicemeter–3), to evaluate their efficacy on survival rate, egg-laying capacity of Biomphalaria alexandrina snails and on histological deteriorations in their hermaphrodite gland. B. alexandrina snails were incubated for 12 hours at each tested concentration in the dark, thereafter they were exposed to direct sunlight (336.2 W/m2) for either 2 or 4 hours followed by 24 hours of recovery. Control snails were treated with these concentrations without exposure to light irradiance. Another experiment was carried out simultaneously and the snails were left for 4 weeks of recovery to evaluate their egg-laying capacity (mx). The results indicate that 5x10–5 mdm–3 (HpdGNPs) with 4 hours of exposure sunlight suppressed the survival rate of B. alexandrina snails by 50%. meanwhile, control snails incubated with 5x10–5 mdm–3 HpdGNPs were not affected and still alive (100%). For snail’s fecundity (mx), treated snails laid low number of eggs throughout the recov-ery period (4 weeks), in comparison with that of control ones. The highest value of mx for snails treated with 5x10–5 mdm–3 Hpd coated GNPs was recorded at the 3rd week of recovery period, being 6.7 eggs/snail, compared to 37.6 eggs/control snail. This has a negative reflect on the reproductive rate (Ro) of treated snails as it was reduced under these conditions by 76.6% and 86.1%, *** tests re-vealed injuries in spermatocytes, oocytes, several degenerations of *** hermaphrodite gland then evacuations in many gonad’s cells which severely suppressed their capacity for egg-laying. It is concluded from the present work that exposing B. alexandrina snails to sublethal concentrations of the photosensiter Hpd coated GNPs (12 hours incubation, 4 hours exposure to 336.2 W/m2) significantly reduced their reproductive capacity that may have a negative ref

The unsteady magnetohydrodynamic flow of an electrically conducting viscous incompressible non-Newto- nian Casson fluid bounded by two parallel non-conducting porous plates has been studied with heat transfer considering the Hall effect. The fluid is acted upon by a uniform and exponential decaying pressure gradient. An external uniform magnetic field is applied perpendicular to the plates and the fluid motion is subjected to a uniform suction and injection. The lower plate is stationary and the upper plate is suddenly set into mo- tion and simultaneously suddenly isothermally heated to a temperature other than the lower plate temperature. Numerical solutions are obtained for the governing momentum and energy equations taking the Joule and viscous dissipations into consideration. The effect of unsteady pressure gradient, the Hall term, the parameter describing the non-Newtonian behavior on both the velocities and temperature distributions have been stud- ied.

The paper investigates the numerical solution of the magnetohydrodynamics (mHD) boundary layer flow of non-Newtonian Casson fluid on a moving wedge with heat and mass transfer. The effects of thermal diffusion and diffusion thermo with induced magnetic field are taken in consideration. The governing partial differential equations are transformed into nonlinear ordinary differential equations by applying the similarity transformation and solved numerically by using finite difference method (FDm). The effects of various governing parameters, on the velocity, temperature and concentration are displayed through graphs and discussed numerically. In order to verify the accuracy of the present results, we have compared these results with the analytical solutions by using the differential transform method (DTm). It is observed that this approximate numerical solution is in good agreement with the analytical solution. Furthermore, comparisons of the present results with previously published work show that the present results have high accuracy.

Objective: Cyclo-oxygenase-2 seems to be involved at various steps in the processes of tumor progression. The abstract Objective of this study was to examine the relationship between cyclo- oxygenase- 2 expression and tumor proliferation, apoptosis and angiogenesis in patients with advanced stage high- grade ovarian carcinoma. study design: specimens from 118 patients with high- grade and advanced stage (III, IV) serous ovarian carcinoma were evaluated by immunohistochemistry for cyclo- oxygenase- 2, Ki- 67, vascular endothelial growth factor, and bcl- 2 expression. Tumor microvessel density was assessed with CD34 immunostaining. We investigated the relationships between cyclo- oxygenase- 2 expression and clinicopathologic characteristics, tumor angiogenesis (tumor microvessel density and vascular endothelial growth factor expression), and tumor proliferation and apoptosis. The effect of cyclo- oxygenase- 2 expression on patient survival was determined. Results: There was a significant positive correlation between cyclo- oxygenase- 2 expression in tumor cells and markers of tumor proliferation and angiogenesis. In univariate survival analysis, high cyclo- oxygenase- 2 and high Ki- 67 expression showed a significant impact of on patient survival (P multivariate regression analysis, only Ki- 67 expression retained its significance as an independent poor prognostic factor (death hazard ratio, 2.0; 95% CI, 1.2- 3.3;P sion: Expression of cyclo- oxygenase- 2 correlates with tumor proliferation and tumor angiogenesis but not with apoptotic markers (bcl- 2 expression) in high- grade, advanced- stage serous ovarian carcinoma. catastrophizing labor pain compromises later maternity adjustments Ferber s.G./Granot m./Zimmer E.Z.
