摘要:
Pharmaceutical compositions for sustained release of pharmaceutical compounds comprising a reaction product of a water soluble salt of a pharmaceutically active compound containing a primary, secondary or tertiary amino group, and an alkali or ammonium salt of a synthetic copolymer containing an acid group, and selected from the group consisting of methacrylic acid/methacrylic acid methyl ester, methacrylic acid/acrylic acid methyl ester and methacrylic acid/acrylic acid methyl ester/methacrylic acid methyl ester copolymers and a pharmaceutically acceptable excipient. The water soluble salt of a pharmaceutically active compound containing a primary, secondary or tertiary amino group is reacted in aqueous medium with an alkali or ammonium salt of a copolymer selected from the group consisting of the above mentioned copolymers, and the resulting product is converted into a pharmaceutical composition.

摘要:
The present invention relates to biocompatible and biodegradable stimuli-sensitive polymeric nanoparticles, which were formed by ion-ion interaction in aqueous media. Synthetic and biological macromolecules with ionizable functional groups are capable of forming nanoparticles whose size and surface properties are sensitive to environmental influences such as pH, temperature and salt concentration. Nanodevices are designed for therapeutic applications as drug and nucleic acid carriers, and/or for MRI diagnosis as contrast agents. These nanodevices are designed for therapeutic applications as targeted drug carriers. Additionally, they can be used as contrast agents for MRI diagnosis. These nanosystems are also potential carriers for delivery of active ingredients as DNA, RNA, short interfering RNA (siRNA), antisense oligonucleotides (AS-ON), and triple helix forming oligonucleotides (TFO) etc. for pharmaceutical applications. Their adjustable size offers yet another advantage.

An improved construction for a lamp cap suitable for interconnecting the elongated constricted neck of a halogen lamp to an electrode-bearing lamp holder is described. A hollow elongated deformable insert is coaxially positioned within a conventional cover disc of the lamp cap. The interior dimension of the insert is chosen to effect a secure frictional engagement with at least 30% of the length of the constricted lamp neck, and is permanently or removably affixed to the surrounding cover disc. The lamp holder may then be affixed to the composite lamp cap to complete the assembly.

A cover adapted to be worn over a user's limb to shield a cast from water exposure includes a shell formed of a single layer of a flexible, water resistant and breathable material. The shell surrounds an interior of the cover, including a lower interior chamber and an upper interior chamber. An open top end communicates with the upper interior chamber and is sized to permit passage of the user's limb and the cast therethrough and into the upper and lower interior chambers. A cinch strap with a releasable securing mechanism closes the open top end around the user's limb. An inner cuff separating the interior chambers includes an elastomeric opening that fits snug against the user's limb, above the cast, and can be tightened using a secondary cinch strap and cooperating fasteners. A segment of water absorbing fabric on an interior surface for absorbing moisture and water.

A replaceable lighting module in an LED light source is provided. The module improves thermal, mechanical, and electrical connection with an associated fixture. The replaceable module also provides for precise positioning and improves on optical properties of the light distribution.
摘要:
A patient interface device adapted to provide an interface between a cornea and a surgical laser system. A frame has an applanation end and an attachment end which is adapted to couple to the surgical laser system. A skirt is affixed to the applanation end of the frame and is adapted to seal against the anterior surface of the cornea to form a chamber. A lens is disposed near the applanation end of the frame and is supported by a flexible support which affixes the lens to the frame.

The invention relates to a manipulated professional antigen presenting cell (APC) having increased expression of a CD1 type II molecule, preferably at least a CD1d molecule, relative to a control non manipulated cell. The invention further relates to the use of PPARg modulators in the preparation of a pharmaceutical composition or kit for the treatment of a disease treatable by activation of CD1d restricted T-cells, e.g. in autoimmune diseases, allergies, post-transplant conditions or infectious diseases, or in the treatment of a neoplastic disease, e.g. skin cancer, hematological tumors, colorectal carcinoma, and therapeutic compositions and kits therefor. Furthermore, the invention relates to methods of manipulating professional APCs and kits therefor.
摘要:
An eye-manipulator can include an applicator-arm and an eye-contact element, the applicator-arm providing mechanical control over the eye-contact element, and the eye-contact element, connected to the applicator-arm, can be configured to make contact with an eye. A method of manipulating an eye includes aligning the eye-contact element with an eye by adjusting the applicator-arm of the eye-manipulator; contacting the eye with the eye-contact element of the eye-manipulator; and manipulating the eye with the eye-manipulator to assist a docking of a patient interface of an ophthalmic system onto the eye.
