The present invention relates to a novel system and method for the determination of depth profiling with improved accuracy and reliability. The method comprises obtaining spectroscopic data from the sample while under at least two different electrical conditions of the sample, the spectroscopic data comprising a signal of charged particles emitted from the sample, and being indicative of a change in amplitude, spectral position and spectral shape of the signal from the sample while under different electrical conditions of the sample, the change being indicative of the compositional profile and spatial distribution for at least one chemical element in the sample along a direction through the sample.

The present invention relates to a drug delivery device that is useful for topical treatment of various infections such as skin and nail, or vaginal infections. More specifically, the invention provides a device for topical administration of allicin to an infection site, comprising either one solid carrier or two adjacent solid carriers, dry alliin and dry alliinase, wherein either a mixture of said dry alliin and dry alliinase is contained within said one solid carrier or dry alliin and dry alliinase are each separately contained within each one of said two adjacent solid carriers, whereby in contact with the infection site and a wetting agent, the alliinase acts on the alliin and allicin is produced in situ and administered to the infection site
摘要:
A charged particle trap for trapping of a plurality of charged particles, and a method of operating said trap. The trap includes first and second electrode mirrors (2,3) having a common optical axis (4), the mirrors being arranged in alignment at two extremities thereof. The mirrors are capable, when voltage is applied thereto, of creating respective electric fields defined by key field parameters. The electric fields are configured to reflect charged particles causing their oscillation between the mirrors. The method includes introducing into the trap, along the optical axis, the plurality of charged particles as a beam (10) having pre-determined key beam parameters. The method further includes choosing the key field parameters for at least one of the mirrors such as to induce bunching among charged particles in the beam.

A device and method for targeting multiple sites of nervous tissue includes an outer elongated element (22), and inner elongated element (12), and multiple micro-wire electrodes (30) partially attached to the inner elongated element. The outer elongated element and inner elongated element are movable with respect to one another, wherein in one configuration the multiple micro-wire electrodes are positioned within the outer elongated element and in a another configuration the multiple micro-wire electrodes are positioned partially outside of the outer elongated element. Multiple micro-wire electrodes may maintain various configurations.

The present invention provides transgenic plants transformed with exogenous nucleic acid encoding a Dunaliella plasma membrane (PM)-ATPase. The transgenic plant has increased tolerance to salt as compared to a corresponding non-transgenic plant. The present invention also provides nucleic acids encoding a chimeric PM-ATPase, which comprise a first portion encoding a plant PM-ATPase or a fragment thereof, and a second portion encoding a Dunaliella PM-ATPase or a fragment thereof. The present invention also discloses a method of producing a transgenic plant having an increased tolerance to salt as compared to a corresponding non-transgenic plant, a method of modifying a plant capacity to survive salt shock, and a method of modifying plant recovery after exposure to salt stress, by introducing into one or more cells of a plant an exogenous nucleic acid encoding a Dunaliella PM-ATPase. Also provided by the present invention are plant cells comprising an exogenous nucleic acid encoding a Dunaliella PM-ATPase, and plant seeds and progeny obtained from the transgenic plants.

摘要:
A method of transplanting a transplant derived from a donor into a recipient is disclosed. The method comprises the steps of (a) transplanting the transplant into the recipient; and (b) administering to the recipient a dose including non-alloreactive anti-third party cytotoxic T-lymphocytes (CTLs), wherein the non-alloreactive anti-third party CTLs are generated by directing T-lymphocytes of the donor against a third party antigen or antigens, the dose is substantially depleted of T-lymphocytes capable of developing into alloreactive CTLs, thereby preventing or ameliorating both graft rejection by the recipient and graft versus host disease.
摘要:
A method and system are presented for producing an output coherent anti-stokes Raman scattering (CARS) signal of a medium. The method comprises generation of a unitary optical excitation pulse that carries a pump photon, a Stokes photon and a probe photon; and inducing a CARS process in the medium by exciting the medium by the at least one such unitary optical excitation pulse. Strong coherent non resonant background, a major problem in single-pulse CARS, is reduced by orders of magnitude by using phase-only pulse shaping or completely supressed by using phase-and-polarisation shaped pulses.
