“Background: find more Measurement of intrapleural pressure is useful during various pleural procedures. However, a pleural manometer is rarely available. Objectives: The aim of this study was to (1) construct an electronic pleural manometer, (2) assess the accuracy of the measurements done with the new device, (3) calculate the costs of the manometer construction and (4) perform an initial evaluation of the device in a clinical setting. Methods: Only widely accessible

elements were used to construct the device. A vascular pressure transducer was used to transform pressure into an electronic signal. Reliability of the measurements was evaluated in a laboratory setting in a prospective, single-blind manner by comparing the results with those measured by a water manometer. Functionality of the device was assessed during therapeutic thoracentesis. The cost of the new pleural manometer was calculated. Results: We built a small, portable device which can precisely measure intrapleural pressure. The measurement results showed very high agreement with those registered with a water manometer (r = 0.999; p < 0.001). The initial evaluation of the electronic manometer during therapeutic thoracentesis showed it was easy to use. The total time needed for 6 measurements after withdrawal of different volumes of pleural fluid in 1 patient did not exceed 6 min. The total cost of the device was calculated to

be <2,000 EUR. Conclusions: In the face of very limited Selleckchem Linsitinib offer of commercially available pleural manometers, it is possible

to successfully construct a self-made, reliable, electronic pleural manometer at modest costs. The device is easy to use and enables data display and storage in the personal computer. Copyright (C) 2011 S. Karger OSI-906 nmr AG, Basel”
“The treatment of rectal cancer has undergone a tremendous surgical evolution over the past century In the past three decades, transanal excision has emerged as a popular treatment option for T1 and selected T2 rectal adenocarcinomas, allowing less morbidity for early cancers The surgical options offered to the patient are the Parks’ per anal excision and the transanal endoscopic microsurgery (TEM)”
“Previously, we reported the use of imidazolium and ammonium based ionic liquids in the absence of chelating agents for the selective liquid liquid extraction of Zn(II), Cd(II), Cu(II), and Fe(III) from hydrochloride aqueous solutions. It was found that the ionic liquid methyltrioctylammonium chloride, [MTOA(+)][Cl-], allowed the almost complete removal of Zn(II), Cd(II), Fe(III) and Cu(II) from the aqueous solutions. In this work, supported ionic liquid membranes based on methyltrioctylammonium chloride were used in an pertraction process for the selective extraction of Fe(III), Zn(II), Cd(II) and Cu(II). The influence of the composition of the receiving phase (milliQ water or Na2CO3, 0.1 M; or NH3,6 M) in the pertraction process was analyzed.
