The hormonal metabolite of vitamin D, 1alpha,25-dihydroxyvitamin D3 [1,25(OH)2D3] is known to inhibit the proliferation of prostatic epithelial cells. This has stimulated interest in vitamin D compounds as therapeutic agents for prostate cancer. However, the therapeutic use of 1,25(OH)2D3 is limited because elevations in serum 1,25(OH)2D3 can cause(More)
Five different selectively deuterated analogs of staphylococcal nuclease (Foggi) were prepared having all but a selected few hydrogen atoms in the enzyme molecule replaced by deuterium. The (1)H-NMR spectra of these analogs are extremely simplified, since they consist of lines arising only from the remaining protonated sites.
Currently, achieving high-fidelity sound spatialization requires the prospective user to undergo lengthy measurements in an anechoic chamber using highly specialized equipment. This, in turn, has increased the cost and reduced the availability of high-fidelity spatialization to the general public. Attempts to generalize 3D audio have been made using the(More)
The forcing of human activity on climate has greatly increased over the last two decades the effort of scientists to deal with the processes involved in global system in depth. Remote sensing plays an increasingly important role in global monitoring, providing an excellent way to obtain, not only continuous in time but global scale information. In this(More)
Among the diversity of Sea Surface Temperature (SST) analysis products which are now being processed under the GODAE (Global Ocean Data Assimilation Experiment) High-Resolution SST Pilot Project (GHRSST-PP) guidelines, the OISST v.2 product presents the most suitable technical characteristics for this study, which are: a daily SST and SST anomalies dataset,(More)
