Abstract: Novel nucleic acid transporters and medicinal compositions for gene therapy.  The nucleic acid transporters are characterized by containing polypeptides consisting of an appropriate number of diaminobutyric acid residues and/or pharmaceutically acceptable salts thereof. These nucleic acid transporters form complexes (i.e., the above-mentioned medicinal compositions for gene therapy) having a high safety and an extremely low immunogenicity with various therapeutic genes, thereby making it possible to efficiently and safely transfer these therapeutic genes into cells by various means and to express the genes at a high ratio in the cells.

Title: Process for introduction of additives and coadjuvants associated with a special thermal treatment for beverage packaging in plastic containers
Inventor: MORETTI ROBERTO HERMINIO
IPC: C12C5/00
Filed: 1998-11-19
Abstract: The process developed by the Applicant is characterized by the introduction into beverages (during one unique or more than one of the phases of the manufacture thereof) of a composition containing: (A) one or more enzymatic complexes comprising glucose-oxidase and catalase; (B) one or more preservative agents and optionally, (C) other food additives, (D) non conventional and mild special thermal treatment so as to allow the use of plastic containers in oxygen-sensitive products and/or requiring some type of thermal treatment like pasteurization, normally impossible to be executed in ordinary plastic containers.  The main function of the enzymatic complex (A) is to catalyse the reactions consuming the oxygen dissolved in the beverage and in the "headspace", without affecting the beverage's sensory characteristics. The enzymatic complex may comprise mainly two enzymes: glucose-oxidase and catalase. The glucose-oxidase catalyzes the reaction of the oxygen with glucose, forming the gluconic acid and the hydrogen peroxide that is later consumed by catalase, forming water and half of the original oxygen. These two are chain reactions which occur until the total consumption of the oxygen. During the shelf-life, the oxygen which permeates through the plastic packaging walls is also consumed through the same process; in case the oxygen is already in the container soon after the packaging, it shall also be consumed in the same manner, giving an extra protection to the product.   The preservatives (B) preserve the beverage microbiologically. The following may be used as preservatives: alkyl p-hydroxibenzoic acid or esters derived thereof, as for example: methyl p-hydroxibenzoic acid ester, ethyl p-hydroxibenzoic acid ester, propyl p-hydroxibenzoic acid ester, butyl p-hydroxibenzoic acid ester, heptyl p-hydroxibenzoic acid ester and octyl p-hydroxibenzoic acid ester. All of them are more active against yeasts and bacteria than benzoic acid, and lower dosages may be used. Jointly, such preservatives have a total and synergistic action, preventing the multiplication of microorganisms. Other food additives (C) may also, optionally, be added, like the antioxidants, eritorbic acid and salts thereof and/or ascorbic acid and salts and/or SO2 thereof and also stabilizers known by brewers, as for example, propylene glycol alginate.  The function of (D) is to empower the (B) activity, in order to guarantee the product's micro-biological stability.     Due to the characteristics of the beverage in which the process proposed has been added, any type of packaging can be used: tin, glass, card or plastic materials; we can mention, for example, packaging type PET, PEN, PVC, PP, PE, PC, PET/PEN blends, one or more polymer multilayers, etc.

Patent CA-2353891-A1 (CA)
Inventor: VAHALA KERRY J
IPC: G02F1/017
Filed: 1999-12-07
Abstract: An optical wave power control device and method enables signal control, such as modulation and switching, to be affected within an uninterrupted propagation element (12, 18), e.g. an optical fiber or planar waveguide. The propagation element is configured such that a portion of its wave guided power encompasses the exterior surface of the element, intercepting the periphery of an adjacent high Q volumetric resonator (20). Power of a chosen resonant wavelength is coupled into the resonator (20), where it circulates with very low loss in accordance with the principles of a whispering gallery mode device, and returns energy to the propagation element (18). By introducing loss within the resonator (20), the propagated power can be varied between substantially full and substantially zero amplitudes. Loss factors can be maintained such that the resonator is overcoupled, i.e. parasitic losses are less than coupling losses, and a critical coupling condition exists in which a small swing in the control effect causes a disproportionate change in the optical output signal.

Inventor: ZHANG JIANZHONG
IPC: G06T1/00
Filed: 1999-05-14
Abstract: A method and apparatus for the imaging of three-dimensional objects is described that includes a structured light source projecting a focused image onto an object by passing either continuous or flashes of collimated source light through an optical grating and projection lens. Apertures in the grating, optionally transmitting a plurality of distinct colors, impose a known pattern on the projected light, separated by opaque areas which reduce color crosstalk to enhance accuracy. A camera responsive to the projected image captures an image of the projected light reflected from an object. Through short-duration image capture, particularly using a short-duration structured light flash synchronized to a camera using a fast shutter speed, high accuracy static 3D  images and measurements of moving or living objects, including humans, can be obtained. The data of the captured image is analyzed to establish and refine the apparent location of points of the reflected pattern.
