摘要:
Complex viruses are assembled from simple protein subunits by sequential and irreversible assembly. During genome packaging in bacteriophages, a powerful molecular motor assembles at the special portal vertex of an empty prohead to initiate packaging. An aspect of the invention relates to the phage T4 packaging machine being highly promiscuous, translocating DNA into finished phage heads as well as into proheads. Single motors can force exogenous DNA into phage heads at the same rate as into proheads and phage heads undergo repeated initiations, packaging multiple DNA molecules into the same head. This shows that the phage DNA packaging machine has unusual conformational plasticity, powering DNA into an apparently passive capsid receptacle, including the highly stable virus shell, until it is full. These features allow for the design of a novel class of nanocapsid delivery vehicles.
摘要:
The present invention provides a method and apparatus for delivering an electric field to a body, comprising delivering a polarized magnetic field in a first direction to a body and directed at a desired target within the body, and changing the delivery direction of the magnetic field to a second direction directed at the desired target to induce an electric field across the desired target.

Enhancing the effectiveness of therapeutic ionizing radiation and other treatments of disease in which cells are to be destroyed or modified, by subjecting cells in need thereof to low-dose radiation to increase the sensitivity of the cells to subsequent subjection with a lethal dose of high dose radiation (HDR), a chemotherapeutic agent, or other type of therapeutic treatment.
摘要:
The present invention describes a partial independent component (PICA) technique for blindly separating partially independent and/or gaussian-like sources from mixed observations over an informative index subspace, which allows various applications in independent component imaging. The present invention estimates a demixing matrix using only the independent and/or nongaussian portion of the observations. The present invention also demonstrates the principle of the approach on both controlled cases and real-world problems, and describes many extended applications of such a technique.
摘要:
An arrangement for inhibiting the adverse effect of an ambient time varying field having an electric component of 5 Kv/M or less and/or a magnetic component of 500 µT or less on a living system. To provide protection, at least one of the characteristic parameters of said field to which the living system is exposed is changed within time intervals of less than 10 seconds.
摘要:
The embodiments of the inventions disclosed in this application develop a 'protection' electric, magnetic or electromagnetic field or fields which are either superimposed upon an ambient field which is detrimental to the health of living systems, or incorporated into the electrical circuit of the device which is generating the detrimental field. Either arrangement is successful in 'confusing' living cells, and thereby reducing the harmful effects of the otherwise detrimental field.
