Abstract:
A synthetic particulate vector comprising a non-liquid hydrophilic nucleus which does not have an external lipid layer grafted thereon. A method for preparing a particulate vector by encapsulating an ionizable active principle, vectors obtainable through said method, and pharmaceutical, cosmetological or food compositions containing such vectors are also disclosed.
Abstract:
A biodegradable particulate vector for transporting biologically active molecules is prepared containing a nucleus for containing a biologically active molecule, a first layer of fatty acid compounds covalently bonded to the nucleus and a second layer of phospholipids hydrophobically bonded to the first layer. The nucleus is between 10 nm and 10 .mu.m in size and is formed of a cross-linked polysaccharide or oligosaccharide matrix onto which ionic ligands are uniformly grafted. The cross-linked polysaccharide may be dextran, cellulose or starch cross-linked with epichlorohydrin. The ligand may be an acidic compound selected from succinic acid, phosphoric acid, citric acid, glycine, alanine, glutamic acid and aspartic acid, or a basic compound such as choline, hydroxycholine, 2-(dimethylamino)ethanol or 2-(dimethylamino)ethylamine fastened onto the matrix via the acidic compound. The polysaccharide or oligosaccharide may be co-cross-linked with a protein such as keratin/collagen or elastase. The vector may be prepared by reacting succinic acid monochloride in aqueous solution with a cross-linked polysaccharide or oligosaccharide matrix to graft succinic acid onto the matrix to form the nucleus, grinding the nucleus to a size between 10 nm and 10 .mu.m, drying the ground nucleus, coupling fatty acid compounds to the nucleus to form a first layer and hydrophobically bonding phospholipids to the first layer to form a second layer. The succinic acid monochloride is preferably prepared by reacting succinic acid dichloride with free succinic acid to form pure crystalline succinic acid monochloride.
Abstract:
A method for modifying the refractive index of an optical polymeric material. The method comprises continuously irradiating predetermined regions of an optical, polymeric material with femtosecond laser pulses to form a gradient index refractive structure within the material. An optical device includes an optical, polymeric lens material having an anterior surface and posterior surface and an optical axis intersecting the surfaces and at least one laser-modified, GRIN layer disposed between the anterior surface and the posterior surface and arranged along a first axis 45° to 90° to the optical axis, and further characterized by a variation in index of refraction across at least one of at least a portion of the adjacent segments and along each segment.
Abstract:
The invention “Ion Trap Array (ITA)” pertains generally to the field of ion storage and analysis technologies, and particularly to the ion storing apparatus and mass spectrometry instruments which separate ions by its character such as mass-to-charge ratio. The aim of this invention is providing an apparatus for ion storage and analysis comprising at least two or more rows of parallel placed electrode array wherein each electrode array includes at least two or more parallel bar-shaped electrodes, by applying different phase of alternating current voltages on different bar electrodes to create alternating electric fields inside the space between two parallel electrodes of different rows of electrode arrays, multiple linear ion trapping fields paralleled constructed in the space between the different rows of electrode arrays which are open to adjacent each other without a real barrier. This invention also provides a method for ion storage and analysis involving with the trapping, cooling and mass-selected analyzing of ions by this apparatus mentioned which constructs multiple conjoint linear ion trapping fields in the space between the different rows of electrode arrays.
Abstract:
A video laryngoscope has a handle and a groove on one side of the handle. The groove is used for guiding a guide wire when the larynogoscope is placed in a patient's mouth. A video camera located near the end of the handle is used to view the area around the glottis. When the guide wire is properly positioned near the glottis, the upper part of the guide wire is disengaged from the groove so as to allow an endotracheal tube to be slipped over the guide wire and to be inserted into part of the trachea through the glottis. When the tube is properly inserted for intubation, the guide wire is removed from the tube. An illuminating light source such as an LED lamp can be installed at the end of the handle to provide illumination for the video camera.
