In each of the subjects under discussion there were intense efforts to determine chemically the active constituent of the medicine. It was success in this field, with the isolation of the alkaloidal constituents of opium, cinchona bark and nux vomica in the first decades of the nineteenth century, that supported the view that scientific pharmacology had its origins at that time. In this interes...

Understanding how comets work--what drives their activity--is crucial to the use of comets in studying the early solar system. EPOXI (Extrasolar Planet Observation and Deep Impact Extended Investigation) flew past comet 103P/Hartley 2, one with an unusually small but very active nucleus, taking both images and spectra. Unlike large, relatively inactive nuclei, this nucleus is outgassing primari...

Phosphocitrate (PC) and its analogue, PC-β ethyl ester, inhibit articular cartilage degeneration in Hartley guinea pigs. However, the underlying molecular mechanisms remain unclear. The present study aimed to investigate the hypothesis that PC exerted its disease-modifying effect on osteoarthritis (OA), in part, by inhibiting a molecular program similar to that in the endochondral pathway of os...

The storage of information in biological memory relies on changes in neuronal circuits, termed plasticity. Synaptic contributions to plasticity, which are an important component, may be divided into changes in existing synapses, and changes in interneuronal connectivity through formation and elimination of synapses. Interneuronal connectivity changes may be further divided into contributions as...

A general f ramework is presented for constructing transforms in the field of the input which have a convolutionlike property. The construction is carried out over finite fields, but is shown to be valid over the real and complex fields as well. It is shown that these basefield transforms can be v iewed as “projections” of the discrete Fourier transform @IT) and that they exist for all lengths ...
