AIM To evaluate whether lead nitrate could replace uranyl nitrate in the Genta stain for H pylori without sacrificing the advantages of the triple stain (Steiner silver impregnation combined with Alcian blue and haematoxylin/eosin (H&E)). METHODS A comparison was made in 16 specimens between the original triple stain and the revised version. One pathologist evaluated all sections. RESULTS D...

Cancer patients with venous thromboembolism (VTE) pose particular management challenges since they have an increased risk of bleeding and recurrent thrombosis compared to the noncancer population. Also, as the disease progresses so do the hazards of anticoagulation, and patients in the palliative stages of their cancer could be viewed as a separate disease group with respect to diagnosis and ma...

Data on the chemistry of biologically active components of petroleum, synthetic fuel oils, certain metal elements and pesticides provide valuable generic information needed for predicting the long-term fate of buried waste constituents and their likelihood of entering food chains. Components of such complex mixtures partition between solid and solution phases, influencing their mobility, volati...

the territory of serbia is vulnerable to various types of natural hazards and the risk is not equal across the entire territory; it varies depending on the type of hazard and the expected potential for damage. the first aim of this research was to determine the geographical distributions of the major types of natural hazards. seismic hazards, landslides, rock falls, floods, torrential floods...

Information hazards are risks that arise from the dissemination or the potential dissemination of true information that may cause harm or enable some agent to cause harm. Such hazards are often subtler than direct physical threats, and, as a consequence, are easily overlooked. They can, however, be important. This paper surveys the terrain and proposes a taxonomy.

gastric cancer is the most prevalent cancer among men and the third most prevalent cancer among women in iran. its most important reason for death is its belated diagnosis at the advanced stages of the disease. various factors can be effective on the survival of these patients after surgery, which are the major concern in this study.data from 330 patients with gastric cancer who had undergone s...

with increasing frequency, the developing countries and the people living there are being affected by disasters. more and more often, development efforts are being destroyed. the reason for this trend is their growing vulnerability, which in turn is the result of economic and social development processes, such as the expansion of settlements and agricultural land in risk areas. the economic and...

Obstetric problems This is the most widely recognised environmental hazard of anaesthesia but individual opinions, as well as governmental and professional reactions, differ widely. Some feel that not enough is being done about the problem while others maintain either that there is no problem and that much research and finance has been misdirected, or that scavenging devices introduce an unacce...

Introduction: This Study has was  carried out to measure and detect the natural occurred radionuclide content including 226Ra, 232Th and 40K in the  Nile River sediments at various locations in Upper Egypt, from Aswan to El-Minya. Additionally, we determine the absorbed dose rate, the annual effective dose equivalent, and excess lifetime cancer risk also has been calculated. Material and Metho...
