Functional dyspepsia constitutes by its impact in quality of life and socio-economic impact areal public health problem (40% of the adult population in the Western world). The prevalence of infection with Helicobacter pylori (HP) in patients with functional dyspepsia is about 30% - 70%. The aim of our study is to observe the improvement of functional dyspepsia (FD) after Helicobacter pylori (HP) eradication. Methods: This is a prospective study over a period of 68 months (May 2009 - January 2015). We included all patients aged over 15 years, with functional dyspepsia defined by the Rome III criteria. The diagnosis of HP was made by histology and/or PCR. Patients infected with HP were treated in single-blind: standard triple therapy for 7 days or sequential treatment for 10 days. HP eradication control was made after: 3 months, 6 months and one year of treatment. Results: During the study period, 1190 patients were included of which 250 patients (21%) were in functional dyspepsia according to the Rome III criteria. The average age in patients with functional dyspepsia was 49 years [16 - 80], sex ratio M/F was 0.58 (N = 92/158). 60% of patients were older than 45 years (N = 150). Chronic smoking was found in 20% of patients (N = 50). One hundred and seventy five patients (70%) had HP infection (N = 175). One hundred and sixty five patients received the treatment of Helicobacter pylori (94.28%), 10 patients were lost to follow (5.71%). The eradication of HP was obtained in 98.41% with sequential treatment versus 88.73% with standard triple therapy (p = 0.026). All patients were reviewed at 3 months and 6 months after treatment, 86% were reviewed at 12 months (N = 143). Dyspeptic symptoms was disappeared in 43% of our patients (N = 71) partial disappearance of symptoms in 34.5% of cases (N = 57) persistence of symptoms in 22.42% of cases (N = 37). Conclusion: In our study the prevalence of Helicobacter pylori infection in patients with functional dyspepsia is high: 70%.

Objective: To evaluate the pattern of various types of visual field defects and their prevalence at initial examination of nonarteritic anterior ischemic optic neuropathy (NA-AION).Methods: The data were compiled from 312 consecutive eyes (in 265 patients)that fulfilled our inclusion and exclusion criteria. A comprehensive ophthalmic evaluation was performed, includingre cording of visual acuity, visual fields with a Goldmann perimeter (using I-2e, I-4e, and V-4e targets regularly), and intraocular pressure; slitlamp examination of the anterior segment;ophthalmoscopy; color fundus photography; and in acute cases, fluorescein fundus angiography. The visual field defects were divided into 2 groups: (1) general field defects and (2)-various types of scotoma in the central 30°. The prevalence of various types of visual field defects was estimated for I-2e, I-4e, and V-4e isopters by dividing the total number of eyes with thedefect by the total number of eyes that could see that particulartarget. Exact 95%confidence limits for the prevalence were computed. Results: Of the 265 patients, 169 (63.7%) were male and the mean±sD patient age was 55.0±9.1 years. The median interval between the first visual field test and the onset of NA-AION was 2 weeks. Of the 312 eyes, the I-2e target was seen by 75.3%, the I-4e target by 90.7%, and the V-4e targetby 100%. Overall prevalence of general visual field defects was 83.4%with I-2e, 78.8%with I-4e, and 68.9%with V-4e,whereas the prevalence of scotoma(s) within the central 30°was 55.3%, 49.5%, and 36.2%, respect ively. Central scotoma was seen in 48.5%with I-2e, 43.8%with I-4e, and 29.2%with V-4e. A detailed prevalence of various types of visualfield defects is given. Relative inferior altitudinal defect was most common (34.9%with I-2e and 22.3%with I-4e), but the absolute inferior altitudinal defect was seen in only 8.0%. bycontrast, absolute inferior nasal sector visual loss was the most common defect detected in NA-AION (22.4%), bu

According to WHO, cancer is a leading cause of death worldwide, accounting for 8.2 million deaths in 2012. Among several factors involved in the pathogenesis of cancer, free radical formation followed by damage to DNA and cell protein is one of the causes. Natural plant products have gained enormous interest in the prevention or treatment of chronic diseases. Ferulic acid, like other phenolic acids (caffeic acid, sinapic acid) possess anti cancer activity. A series of ferulic esters (FE1 - FE11) and ferulic amides (FA1 - FA10) were synthesized and evaluated for their cytotoxic activity.

When heavy machines and large scaled receiver system of communication equipment are manufactured, it always needs to produce large-sized steel castings, aluminum castings and etc. some defects of hot cracking by thermal stress often appear during solidification process as these castings are produced, which results in failure of castings. Therefore predicting the effects of technological parameters for production of castings on the thermal stress during solidification process becomes an important means. In this paper, the mathematical models have been established and numerical calculation of temperature fields by using finite difference method (FDM) and then thermal stress fields by using finite element method (FEM) during solidification process of castings have been carried out. The technological parameters of production have been optimized by the results of calculation and the defects of hot cracking have been eliminated. Modeling and simulation of 3D thermal stress during solidification processes of large-sized castings provided a scientific basis, which promoted further development of advanced manufacturing technique.

Arsenic is often occured in sulphide gold-containing ores and concentrates. The principal minerals of these materials are arsenopyrite （FeAss）, auripigment （As2s3）, realgar（As2s2） and lollingite （FeAs2）. In pyrometallurgical processing of raw materials, arsenic is sublimated mainly in the form of very toxic heavily trapped white arsenic contaminating dusts, sublimates and par
