Four different purified hyaluronidases have been approved for use in the United States, three of animal origin and one recombinant. They are indicated as adjuvants in subcutaneous fluid administration for achieving hydration, for increasing the dispersion and absorption of other injected drugs, or for improving resorption of radiopaque agents, in subcutaneous urography.
Membrane keyboard as used on the East German Robotron Z1013. A membrane keyboard is a computer keyboard whose keys are not separate, moving parts, as with the majority of other keyboards, but rather are pressure pads that have only outlines and symbols printed on a flat, flexible surface.

Whereas Microsoft mice and Microsoft keyboards were previously controlled from two separate programs – IntelliPoint and IntelliType – the Mouse and Keyboard Center is responsible for both kinds of devices. 32- and 64-bit versions of the software are available, and the program integrates with Windows 8 and above's "Modern UI" interface.
By using computer programs, a person can open, read, change, save, and close a computer file. Computer files may be reopened, modified, and copied an arbitrary number of times. Files are typically organized in a file system, which tracks file locations on the disk and enables user access.
The enzyme hyaluronate lyase (EC 4.2.2.1) catalyzes the chemical reaction. Cleaves hyaluronate chains at a β-D-GalNAc-(1→4)-β-D-GlcA bond, ultimately breaking the polysaccharide down to 3-(4-deoxy-β-D-gluc-4-enuronosyl)-N-acetyl-D-glucosamine
Hydrogen oxidation is coupled to the reduction of electron acceptors such as oxygen, nitrate, ferric ion, sulfate, carbon dioxide (CO 2), and fumarate.On the other hand, proton reduction is coupled to the oxidation of electron donors such as ferredoxin (FNR), and serves to dispose excess electrons in cells (essential in pyruvate fermentation).
