This method avoids the direct use of highly toxic acids and bases, produces β-isothiocyanato carbonyl products in yields of 87–98% under mild conditions (less than 6 hours at 0 °C), and displays wide functional group tolerance. Density functional theory calculations highlighted competing ...
The present review focuses on the recent trends as applicable in the use of 2D GO–aptamer conjugate materials for the detection of main types of cancer biomarkers. The selection process of aptamers and their suitability as a replacement for antibodies in cancer diagnosis has been explained. Functi...
The lack of a clear booster effect in the sustained high-titer IgM and IgG response after vaccinations three and five months following the initial series may be explained by the fact that the patients were immunized at two-week intervals initially. In the classical experiment showing the ...
Although the effects of successive substitutions on the STO-3G structures are generally systematic, a few apparent anomalies are readily explained in terms of resonance stabilization. Calcns. at the 3-21G level, on the STO-3G optimized structures, indicate that the stabilization energy assocd. ...
