A database structure of a sort defined by an access and query language that defines tables of variables having labels and field characteristics, such as ANSI structured query language (SQL), is modified by determining the structural differences between an existing schema and a new schema, independent of database contents. The differences are processed to generate commands that are then applied to evolve an existing database from the old schema or structure to the new one. This avoids the need to dump and restructure the contents of the old database for reload into an empty new database that has been prepared to meet the new schema.

Structural differences in binding pockets of members of the HSP90 family can be exploited to achieve differential degradation of kinases and other signaling proteins through the use of designed small molecules which interact with the N-terminal binding pocket with an affinity which is greater than ADP and different from the ansamycin antibiotics for at least one species of the HSP90 family. Moreover, these small molecules can be designed to be soluble in aqueous media, thus providing a further advantage over the use of ansamycin antibiotics. Pharmaceutical compositions can be formulated containing a pharmaceutically acceptable carrier and a molecule that includes a binding moiety which binds to the N-terminal pocket of at least one member of the HSP90 family of proteins. Such binding moieties were found to have antiproliferative activity against tumor cells which are dependent on proteins requiring chaperones of the HSP90 family for their function. Different chemical species have different activity, however, allowing the selection of, for example Her2 degradation without degradation of Raf kinase. Thus, the binding moieties possess an inherent targeting capacity. In addition, the small molecules can be linked to targeting moieties to provide targeting of the activity to specific classes of cells. Thus, the invention further provides a method for treatment of diseases, including cancers, by administration of these compositions. Dimeric forms of the binding moieties may also be employed.

A technique for interference suppression in MC-CDMA systems is proposed which exploits the structural differences in signals that arrive at the receiver with Doppler shifts or carrier offsets. Oversampling the received signal in the frequency domain and properly combining the samples provides the interference suppression. Frequency domain oversampling is accomplished by using a time extension of the conventional MC-CDMA signal. Furthermore, a receiver structure is introduced that despreads and combines groups of samples so that a linear minimum mean-squared error solution for combining the groups is easily found. This combining scheme increases the signal-to-interference ratio (SIR) experienced by the desired user in the MC-CDMA system. In addition, the receiver performs well in severe near-far scenarios when there is sufficient Doppler separation between the signals of the desired user and an interferer. Numerical results show that the proposed receiver significantly outperforms the conventional MC-CDMA receiver.

The invention discloses a sodium nitroprusside-conjugated medicine-carrying prussian blue analogue nano-photothermal therapeutic agent and a preparation method thereof. The particle size of the sodiumnitroprusside-conjugated medicine-carrying prussian blue analogue nano-photothermal therapeutic agent prepared by a hydrothermal reaction method is 205.4nm, and passive targeting can be achieved by means of an enhanced permeability and retention (EPR) effect of a tumor site. Under the illumination of near-infrared laser, the nano-photothermal therapeutic agent can not only induce photothermal ablation of tumor cells through excellent photothermal conversion efficiency, but also can control NO release, thereby improving the EPR effect and increasing intratumoral delivery of nanoparticles. Furthermore, the NO can also inhibit tumor progression by inducing apoptosis of the tumor cells, preventing angiogenesis, reversing multidrug resistance, and the like. On the other hand, due to the structural difference between sodium nitroprusside and potassium ferricyanide, the lattice defects of the nanoparticles are caused, and the drug loading capacity of the nano-photothermal therapeutic agent is accordingly increased. Therefore, after chemotherapeutic drugs are carried, under the irradiation of near-infrared light, the nano-photothermal therapeutic agent can realize dose-controlled NO release and phototherapy and chemotherapy combined oncotherapy. In addition, the sodium nitroprusside-conjugated medicine-carrying prussian blue analogue nano-photothermal therapeutic agent provided by theinvention also has good photothermal stability and certain photoacoustic contrast properties.
