Abstract: Methods for converting mixtures of anthocyanins occurring in fruit or vegetable juice or extract into particular anthocyanin molecules having desirable colorant properties are provided herein. The method of the present disclosure can be employed to increase the amount of particular anthocyanin molecules, while lowering the total number of anthocyanin molecules present in the natural juice and/or extract. The disclosure is also directed to anthocyanin molecules prepared by the methods of present disclosure and to enzymes capable of catalyzing reactions that provide such effects.

Abstract: A light curing dental system comprising a light emitting tray that precisely distributes an optimal amount of curing light energy to internal, external and extra oral portions of the dental arch to cure a dental material. The light curing dental system generally includes a light source, a light emitting dental tray, an activation module and a photocurable dental material.

Abstract: The invention relates to a computer-implemented method comprising the steps of: (S100) presenting a surface (S) comprising segments derived from volumetric data (VD) in a virtual reality user interface (6); (S200) presenting volumetric data (VD) in the virtual reality user interface (6); (S300) applying a signed distance field technique (SDF) to the segments in reference to the presented volumetric data (VD); (S400) adjusting at least one of the segments based on a result of applying the signed distance field technique (SDF) so that the presented surface data complies with the presented volumetric data (VD); and (S500) saving the adjusted at least one of the segments in a data file (DF) separately from a data file of the volumetric data (VD).

Abstract: Disclosed are methods for determining the energy of a particle beam, for example a proton beam, by measuring the ratio of the radioactivities associated with two radioisotopes that are simultaneously produced within a plurality of target foils versus the calculated beam energy drop through each individual foil. This method relies on the disparate production of related radioisotopes in a single material as a function of the beam energy. A calibration curve may be established by irradiating target metal foils of known thickness and measuring the relative radioactivities of at least two target radioisotopes resulting from that irradiation. In particular, the method can be used to determine beam energies in the 10 to 18 MeV range by measuring the relative production of 63Zn and 65Zn in natural Cu foils.

Abstract: An apparatus for producing 18F-Fluoride by using a particle beam to irradiate conversion medium in gaseous or liquid form. The irradiated conversion medium is contained in a chamber surrounded by a Fluoride adsorbing material to which the produced 18F-Fluoride adheres. The adsorption properties of the Fluoride adsorbing material are manipulated by an adsorption enhancing/decreasing element. A solvent dissolves the produced 18F-Fluoride off of the Fluoride adsorbing material while it is in the chamber. The solvent is then processed to obtain the 18F-Fluoride.

Abstract: A system and method for producing 18F-Fluroide by using a proton beam to irradiate 180xygen in gasous form. The irradiated 180xygen is contained in a chamber that includes at least one component to which the produced 18F-Fluoride adheres. A solvent dissolves the produced 18F-Fluoride off of the at least one component while it is in the chjamber. The solvent is then processed to obtain the 18F-Fluoride.

Abstract: The present invention relates to a method for implantation of Xe isotopes in a matrix for production of 125I sources that do not shed radioactive atoms. 125Xe implanted at 12 kV in steel, titanium and gold does not evolve after more than 10 half-lives (380 h) and 125I from the decay of implanted 125Xe is equally stable for 2 half-lives (120 d). The matrix having radioxenon implanted is useful as a medical device, for instance as a “seed” for radiotherapeutic uses or in production of stents. Methods of treatment utilizing such devices are also encompassed by the present invention.
