Title: Novel reovirus-derived proteins, nucleic acids encoding same, and uses therefor
Inventor: DUNCAN ROY
IPC: C12P21/02
Filed: 1998-11-06
Abstract: In accordance with the present invention, viral proteins that are responsible for membrane fusion and syncytium formation induced by three different fusogenic orthoreoviruses, i.e., avian reoviruses (ARV), Nelson Bay virus (NBV), and Baboon Reovirus (BRV), have been identified. The genes encoding these proteins have been cloned and sequenced; functional analysis thereof indicates that expression of these proteins in transfected cells results in cell-cell fusion.

Title: Method for the extraction of a substance from a starting material and extraction apparatus for carrying out the method
Inventor: HULLEMAN STEPHAN HENRICK DICK
IPC: B01D11/02
Filed: 1998-11-19
Abstract: The invention relates to a counter-current extraction process with which the starting material to be extracted is conveyed in an extruder through zones of high and low pressure. The zones of high and low pressure can, for example, be formed by different screw elements of opposing pitch. Extractant is fed in in the high pressure zones which are located upstream of the screw elements of opposing pitch. The extractant then flows in counter-current to a discharge opening which is located in or close to the low pressure zone, downstream of a screw element of opposing pitch. With the extraction method according to the present invention a stable counter-current extraction process can be obtained over a very short extraction length and a high extraction yield can be achieved within a short time by intensive mixing of the starting material with the extractant. Furthermore, high pressures can be used in the extraction apparatus according to the present invention since the discharge openings are located close to the low pressure zones. As a result the extraction yield is further increased and extraction fluids in supercritical state can be used.

Title: Dna replication proteins of gram positive bacteria and their use to screen for chemical inhibitors
Inventor: ZHANG DAN
IPC: C12N9/90
Filed: 1999-01-25
Abstract: The duplex DNA of chromosomes is replicated in a multicomponent process. A helicase unwinds the DNA, a replicase synthesizes new DNA, and primase repeatedly synthesizes new primed starts on the lagging strand. The present invention is directed to the genes from Gram positive bacterium encoding these proteins, and their characterization. Replicases are highly efficient polymerases. There are several mechanisms by which a replicase can achieve high processivity. The invention determines that the replicase of Staphylococcus operates as a 3 component system in which a clamp loader enzyme assembles a sliding clamp protein onto DNA. The sliding clamp then binds the DNA polymerase III holoenzyme making it highly efficient. The invention identifies two DNA polymerase III enzymes in Gram positive bacterium, each of which operate with the clamp and clamp loader, to extend a single primed site around a long (over 5kb) ssDNA template. These replication proteins can be utilized in a variety of assays to screen chemical compound libraries for an antibiotic compound.

Title: Multi-level security network system
Inventor: WILLIAMS TIMOTHY C
IPC: G06F21/00
Filed: 1999-07-21
Abstract: A network prevents unauthorized users from gaining access to confidential information. The network has various workstations (14) and servers (16) connected by a common medium (20) and through a router (22) to the Internet (30). The network has two major components, a Network Security Center (NSC) and security network interface cards or devices (5). The NSC is an administrative workstation through which the network security officer manages the network as a whole as well as the individual security devices. The security devices are interposed between each of the workstations, including the NSC, and the common medium and operate at a network layer (layer 3) of the protocol hierarchy. The network allows trusted users to access outside information, including the Internet, while stopping outside attackers at their point of entry. At the same time, the network limits an unauthorized insider to information defined in their particular security profile. The user may select which virtual network to access at any given time. The result is trusted access to multiple secure Virtual Private Networks (VPN), all from a single desktop machine.

Abstract: The present invention utilizes dielectric slabs to provide a relatively uniform electromagnetic field to a cavity between two or more dielectric slabs. Each dielectric slab is a thickness equal to or nearly equal to a quarter of a wavelength of the electromagnetic field in the dielectric slab. In a particular embodiment, sample material is introduced into the cavity between the two dielectric slabs. This sample material may be introduced through one or more openings in the dielectric slabs. In further embodiments, specialized choke flanges prevent the leakage of energy from this cavity. In a preferred embodiment, an elliptical conducting surface directs the electromagnetic field to a focal region between the two dielectric slabs. Openings to this focal region allow sample material to be passed through this region of focused heating.
