aim : this study was conducted to evaluate the influence h. pylori infection and anti- caga status on the efficacy of omeperazole 20 m.g. b.d. for patients with endoscopic oesophagitis. background : the influence of helicobacter pylori (h. pylori) infection and its virulent strain (cytotoxin-associated gene a: caga ) has not been evaluated on efficacy of treatment for patients with erosive oeso...

Background: Increased mean platelet volume (MPV) is a central process in the pathophysiology of coronary artery disease (CAD). Objectives: To investigate whether assessment of MPV, besides the traditional risk factors, enhances the assessment process for the risk of acute coronary syndrome (ACS). Materials and Methods: This study included 81 patients, divided into 2 groups; group I included 61 ...

Suppose one has a virtual model of a car engine and wants to use an immersive virtual environment (VE) to determine whether both a large man and a petite woman can readily replace the oil filter. This real world problem is difficult to solve efficiently with current modeling, tracking, and rendering techniques. Hybrid environments, systems that incorporate real and virtual objects within the VE...

Cr(III), Co(II), Ni(II), Cu(II) and Zn(II) salts of 2-(4-nitrophenylaminocarbonyl)benzoic acid were characterized by physical, analytical and spectroscopic studies and checked for their  in-vitro antimicrobial activity against three bacterial strains, Mycobacterium smegmatis (Gram +ve), Escherichia coli (Gram -ve), Pseudomonas aeuroginosa (Gram -ve) and three fung...

UNLABELLED BACKGROUND Overexpression of the tumor suppressor gene p53 and the marker for cellular proliferation Ki67 in open lung biopsies are indicated as predictor factors of survival of patients with lung cancer. However, the prognostic value of p53 and Ki67 in fiberoptic bronchial biopsies (FBB) has not been fully investigated. We evaluated p53 and Ki67 immunostaining in FBB from 19 with...

This study aimed to evaluate the effects of vitamin E (VE), ferulic acid (FA) and their combination supplementation on meat quality and antioxidant capacities of finishing pigs. Sixty barrows were randomly allocated to four experimental diets using a 2×2 factorial arrangement with 2 VE supplemental levels (0 or 400 mg/kg) and 2 FA supplemental levels (0 or 100 mg/kg) in basal diets. After 28 da...

While the traditional R value is useful to evaluate the quality of a t, it does not work when it comes to evaluating the predictive power of estimated nancial models in nite samples. In this paper we introduce a validated R V value that is Taylor made for prediction. Based on data from the Danish stock market, using this measure we nd that the dividend-price ratio has good predictive power for ...

Background: Rice seed proteins are lacking essential amino acids (EAAs). Genetic engineering off ers a fast and sustainable method to solve this problem as it allows the specifi c expression of heterologous EAA-rich proteins. The use of selectable marker gene is essential for generation of transgenic crops, but might also lead to potential environmental and food safety problems...

We have carried out a survey of C2H and HCN in a wide sample of evolved stars using the 30-m IRAM telescope. Significant variations of the C2H abundance are found between the observed stars. Low C2H abundances, X(C2H)<10−5, are observed in S-stars, and detached envelopes. In massive C-rich stars (Ṁ > 2 10−6 M yr−1) the C2H abundance seems to be correlated with the expansion velocity. Thus, the ...

he ever-increasing power of computers and hardware rendering systems enables the creation of visually rich and perceptually realistic virtual environment (VE) applications. At the same time, comparatively little effort has gone into the user interaction components of VEs. Although usability engineering is a newly emerging facet of VE development, user-centered design and evaluation in VEs as a ...
