Antisense technology has great potential for the control of RNA expression, but there remain few successful applications of the technology. Expressed antisense RNA can effectively down-regulate expression of a gene over long periods, but cannot differentiate partly identical sequences, such as the mRNA of fusion genes or those with point mutants. We have designed a structured form of expressed ...

Silicon nanowire field effect transistors (FETs) have emerged as ultrasensitive, label-free biodetectors that operate by sensing bound surface charge. However, the ionic strength of the environment (i.e., the Debye length of the solution) dictates the effective magnitude of the surface charge. Here, we show that control of the Debye length determines the spatial extent of sensed bound surface c...

This work deals with the configuration interaction method when an N-electron Hamiltonian is projected on Slater determinants which are classified according to their seniority number values. We study the spin features of the wave functions and the size of the matrices required to formulate states of any spin symmetry within this treatment. Correlation energies associated with the wave functions ...

In the title compound, C(18)H(24)NO(2) (+)·Cl(-), the absolute configuration of the new stereogenic centre (the C atom with a CH(2)OH substituent) was unambiguously determined to have an R configuration. The dihedral angle between the two aromatic rings is 30.82 (2)°. Inter-molecular N-H⋯Cl and O-H⋯Cl hydrogen bonds and intra-molecular N-H⋯O hydrogen bonds stabilize the crystal structure.
