Perkin and Resnik advocate the use of muscle relaxants to prevent the "agony of agonal respiration" arguing that this is compatible with the principle of double effect. The proposed regime will kill patients as certainly as smothering them would. This may lead some people to reject the argument as an abuse of the principle of double effect. I take a different view. In the absence of an adequate...
Materials and Methods: All the reagents were received from Sigma Aldrich Chemical Co. and used without further purification. Solvents were purchased from commercial sources and purified by reported protocol.1 Spectroscopy grade solvents were used for physical studies. 1H NMR and 13C NMR experiments were done on a Bruker DPX-400 MHz and 500 MHz NMR machine and all the data were calibrated agains...
Perkin-Elmer defines the term ’computer-aided chemistry’ as the application of a computer, of any size, to the solution of an analytical chemistry problem. More specifically, the computer is a tool which is applied to tasks of either a tedious, repetitive, or very complex nature so that the analytical chemist is freed to apply his reasoning power. This paper was prepared for a session on ’Solvi...
Human immunodeficiency virus (HIV) RNA testing is the gold standard for monitoring antiretroviral therapy in HIV-infected patients. However, equipment and reagent costs preclude widespread use of the assay in resource-limited settings. The Perkin-Elmer Ultrasensitive p24 assay and the Cavidi Exavir Load assay both offer potentially simpler, less costly technologies for monitoring viral load. Th...
Source and Description. A partial genomic library (300 to 500 bp) was constructed using DNA obtained from Japanese flounder,Paralichthys olivaceus, digestedwith Sau3AI. The DNA was inserted in pBluescript SK (Toyobo, Japan) digested by BamHI and transformed into competent E. coli cells (strain DH5α). The partial genomic library was screened with a γP-labeled (CA)10 probe. About 800 positive clo...
