Background. All elderly 65 years and older are recommended by the U.S. Advisory Committee on Immunization Practices to receive pneumococcal vaccination, with a coverage goal of 90% per the Healthy People 2020 objectives. This study aimed to provide real-world data on pneumococcal vaccination coverage and factors associated with receiving pneumococcal vaccination in a large U.S. managed care eld...

objective(s) the liver has major role in the organism homeostasis, interactions with other systems, synthesis and metabolism of bile production, drug detoxification and hormone inactivation. cholestasis can be defined as an impairment of the bile flow which can lead to hepatocytes necrosis and finally cirrhosis. some studies reported a gastric acid secretion reduction in cirrhotic subjects, whi...

background: skin flap grafting is a popular approach for reconstruction of critical skin and underlying soft tissue injuries. in a previous study, we demonstrated the beneficial effects of two 5α-reductase inhibitors, azelaic acid and finasteride, on tissue survival in a rat model of skin flap grafting. in the current study, we investigated the involvement of nitric oxide and inducible nitric o...

Abstract A number of factors determine the mechanical, but also physical and chemical properties. One most important are steel microstructure its working conditions. few corrosion processes in crevices awkward corners can be avoided at design stage (low roughness parameters, round-section other). But still construction material is exposed to corrosion. These steels often come into contact with ...

The trace element content of thirty-two nuts including almonds, walnuts, hazelnuts and pistachios available in a Greek market was determined by inductively coupled plasma atomic emission spectrometry (ICP-AES). Wet acid digestion using nitric (65%) took place Teflon autoclaves. limits detection (LODs) quantification (LOQs) ranged between 0.01 (Mg)–2.52 (Cu) ?g g?1 0.02 (Mg)–8.40 g?1, respective...

nano-sized titanium dioxide tio2 powder was successfully prepared from its precursor titanium (iv) chloride by a simple and new wet chemical method. ticl4 were used as precursor in hydrogen peroxide, h2o2 and ethanol. this solution was then peptized using nitric acid and heated under reflux at 80°c. their physico-chemical properties were then characterized by transmission electron microscopy (t...
