Disclosed are cellulose capsules, methods for preparing a cellulose capsule, and compositions comprising cellulose capsules, including sustained- or controlled-release dosage forms comprising cellulose capsules.
Abstract:
A device may provision two or more servers, each of the servers including a first network interface. In addition, the device may enable a second network interface in each of the provisioned servers, create a shared volume, assign the shared volume to each of the provisioned servers, and enable a clustering application on each of the provisioned servers to form a cluster comprising the provisioned servers, the cluster having a heartbeat via the second network interfaces.
Abstract:
A decision support system called Mounties that is designed for managing applications and resources using rule-based constraints in scalable mission-critical clustering environments. Mounties consists of four active service components: (1) a repository of resource proxy objects for modeling and manipulating the cluster configuration; (2) an event notification mechanism for monitoring and controlling interdependent and distributed resources; (3) a rule evaluation and decision processing mechanism; and (4) a global optimization service for providing decision making capabilities. The focus of this paper is on the design of the first three services that together connect and coordinate the distributed resources with the decision making component.
Abstract:
A new cellulose excipient, OCCAE, suitable for use as a binder, filler, and/or disintegrant in the development of solid dosage forms and as a bodying agent or a drug carrier in the preparation of topical formulations is described. The cellulose excipient is formed by reacting an oxidized cellulose ester with an alcohol in the presence of a catalyst. The invention also describes the formation of controlled release microspheres using OCCAE and/or oxidized cellulose esters that may be used to control the release of drug in a patient over a time period of several hours to several days.
Abstract:
The present invention relates to the preparation of a series of oxidized cellulose esters suitable for use as a drug carrier in the development of biodegradable controlled and/or sustained release pharmaceutical, agricultural, and veterinary compositions, such as films, compacts, microspheres, and pellets. The esters are prepared by acylation of oxidized cellulose having at least 3% carboxyl groups. The resulting oxidized cellulose esters are soluble in aqueous alkaline solutions, water, and a variety of organic solvents.
Abstract:
There is provided a method for the detection of phytase activity in a sample, which comprises bringing into association a phytase substrate and said sample, and measuring the level of an organic metabolite of said phytase substrate.
Abstract:
The present invention relates to enzymes and processes. In particular, there is described a host cell transformed or transfected with a nucleic acid encoding a bacterial phytase enzyme and variants thereof.

Abstract:
A method and system offer confidential purchase of electronic data which can be used without any need of knowledge in cryptography nor mastery of computer use beyond usual usage of the World Wide Web (WWW). The method and system which guarantee confidentiality as long as there is no collusion between agents working for a large number of reputable companies whose references can be easily checked on the Internet before proceeding to the order. In addition, the method and system allow for guaranteed payment and offer recourse in case of improper delivery.
Abstract:
The present invention describes the use of regenerated celluloses (RC) and (ORC) oxidized regenerated celluloses in the manufacture of scaffolds for drug delivery and tissue engineering. The RC and ORC are biodegradable and biocompatible. The carboxyl, aldehyde, or ketone groups present on the ORC scaffold serve as sites for cell, drug, protein and/or peptide attachment or further chemical modification to induce cell adhesion and subsequent proliferation. The method of manufacture of these membrane structures is simple, and produces flexible structures that maintain their strength when hydrated.
