Title: The use of endoperoxides for the treatment of infections caused by flaviviridae, including hepatitis c, bovine viral diarrhea and classical swine fever virus
Inventor: SAS BENEDIKT
IPC: A61K45/06
Filed: 2003-10-29
Abstract: The use of sesquiterpenes and, in particular sesquiterpene lactone endoperoxides, such as artemisinin and analogs thereof, for the treatment of hepatitis C virus infections. Artemisinin, analogs of artemsisnin and some crude Artemisia extracts were tested in vitro against DNA-viruses, retro-viruses and Flavivirida, (an important family of human and animal RNA  pathogens). These compounds were also screened for anti-tumor activity. Strong activity of artemisinin was noticed against the bovine viral diarrhea virus (BVDV). As pestiviruses, such as BVDV, share many similarities with hepatitis C virus (HCV), we can conclude that endoperoxides in general and artemisinin more specificly have efficacy as treatments for hepatitis C viral infections.

Abstract: A cutting tool for attachment to the leading area of a base is provided. The cutting tool includes a holder base having two substantially parallel cutting teeth extending from the holder base, the cutting teeth each having a cutting edge and an opening between the teeth. The cutting teeth define first and second cutting paths. The cutting teeth impact and cut asphalt shingles, and funneling surfaces of the teeth funnel the cut shingle material toward and through the opening, and into the path of the rear cutting member which cuts the material a second time. Thus, asphalt shingles are processed more efficiently, thereby creating less frictional heat and avoiding melting of the asphalt shingles.

Abstract: Reproduction AV data obtained from an optical disc (41) is accumulated in an RAM (50). An AV signal whose reproduction start timing is controlled is output from the RAM (50). A viewer aspiration is measured by a sensor (61). The signal measured is supplied via a low pass filter (62) to a peak detection circuit (63) and the timing of the peak value is detected. According to the peak value detected, a change point detection circuit (64) detects a change point from the exhalation period to the inspiration period of the viewer and generates a reproduction start signal. The reproduction start signal is supplied to the RAM (50) and the read out timing of the AV signal from the RAM  (50) is controlled to be synchronized with the reproduction start signal. By controlling the timing of the AV information start according to the viewer biological information, it is possible to reproduce a situation matched with the actual performance, breathing in performance, and excitation.

Abstract: A touch system (10, 150, 250) includes a touch surface (60, 160, 260) on which an image is displayed and at least one camera (66, 170, 266) acquiring images of the touch surface. A pointer contact data generator generates pointer position data in response to pointer contact with the touch surface. The pointer position data represents the location of the pointer on the touch surface where pointer contact is made. A processor (56, 156, 256) communicates with the at least one camera and the pointer contact data generator. The processor uses known points in the displayed images to calibrate automatically co-ordinate systems of the touch system, and uses calibrated pointer position data to update image data that is used to present the displayed image on the touch surface. In one embodiment, the touch system includes an active touch sensitive screen (252). In another embodiment, image data generated by a pair of cameras (66) having overlapping fields of view is used by the pointer contact data generator to generate the pointer position data when a pointer is acquired in images captured by the pair of cameras.
