A percutaneously implantable orthopedic device is a shape-changing joint prosthesis with a generally arcuate or generally rectilinear configuration which is delivered through a delivery device in a substantially straightened or slightly curved configuration into a joint in a patient. The generally arcuate configuration may include an open ring or spiral shape. The generally rectilinear configuration may include a polygon or zig-zag shape. The delivery and retrieval device can be a syringe, hypodermic needle or cannula. The orthopedic device is moveable into its generally arcuate or generally rectilinear configuration in the joint by manipulation or a shape memory set. The orthopedic device acts as a soft compliant bearing surface or cushion that minimizes the bone-on-bone wear from articulation and loading.

A process for producing an arginine-rich peptide mixture and the application thereof in cervical cancer therapy is provided. The process includes the following steps: A suspension of walnut meal and egg albumin is pretreated with ultrahigh pressure, and then digested by alkaline proteinase and papain in separated steps with the ultrasonic and microwave-assisted extraction. The peptides of interest are isolated from filtration supernatant obtained after the enzyme digestion by reversed phase high-performance liquid chromatography. By using the peptide mixture as a template, acrylic acid and methyl acrylic acid as functional monomers, triethylene glycol dimethacrylate as cross-linking agent, and isopropylthioxanthone in acetone as a photoinitiator, polymerization is induced by ultraviolet light to form a surface imprinted membrane for isolating and enriching the peptides of interest from the supernatant. The arginine content in the peptide mixture is more than 18%. The arginine-rich peptide mixture is able to strongly suppress the proliferation of human cervical cancer Hela cells. The approach is applicable to reduce the cost of production and speed up the commercialization of large-scale production.

The present invention concerns a method for the treatment of inflammatory arthritis, and in particular rheumatoid arthritis, by administering to the subject specific low dosages of N6-(3-iodobenzyl)-adenosine 5′-N-methyl-uronamide (IB-MECA) and 2-chloro-N6-(3-iodobenzyl)-adenosine-5′-N-methyl-uronamide (CL-IB-MECA).

A battery charging method and device thereof are disclosed. The method includes the following steps. First, a charging current is supplied into a plurality of cell blocks of a battery module for charging, and the terminal voltages of the cell blocks are detected, when one of said terminal voltages exceeds a first threshold, the charging is kept continuously over a first preset time period. If one of said terminal voltages of said cell blocks exceeds a second threshold, an over voltage protection is performed, else the charging current is reduced and the battery module is charged by the reduced charging current continuously over a second preset time period and if the cell blocks are determined that they are fully charged, the charging is stopped, otherwise, the battery module is charged continuously. Therefore, the battery charging method and device thereof in accordance with the present invention can prevent the battery module from being overcharged and prolong its life.

A lead frame for an optical semiconductor device, having a reflection layer at least on one side or each side of the outermost surface of a substrate, partially or entirely, in which the reflection layer has, on the outermost surface at least in a region where light emitted by an optical semiconductor element is reflected, a microstructure with at least the surface thereof having been mechanically deformed, which is converted from a plating microstructure formed of a metal or an alloy thereof; a method of producing the same, and an optical semiconductor device having the same.

A lithium ion secondary battery includes a positive electrode, a negative electrode, a non-aqueous electrolyte, and a separator interposed between the positive electrode and the negative electrode. The separator includes a polyolefin layer and an oxidation-resistant layer. The oxidation-resistant layer includes an oxidation-resistant polymer. A main chain of the oxidation-resistant polymer does not include a —CH2— group and a —CH(CH3)— group. The oxidation-resistant layer faces the positive electrode.
