Abstract: The present dental handpiece has a burr sleeve, a head section, an air supply passage for introducing compressed air into the head section for driving the burr sleeve, and an air discharge passage for discharging the compressed air. The air supply passage includes a through hole axially extending through the rear terminal part of the handpiece, and a tubular pressure regulating member and an air supply tube connected in series between the through hole and the head section. The pressure regulating member has an aperture for allowing communication with the air discharge passage, and an annular valve body arranged axially slidably for opening/closing the aperture. When the pressure of compressed air passing through the air supply passage exceeds a predetermined level, the valve body is slid to open the aperture to discharge the compressed air for regulating the pressure of the compressed air to be supplied to the burr sleeve.
Abstract: The present invention relates to the use of Echinacea or Echinacea preparations for the manufacture of pharmaceutical compositions which can be used to relieve natural occurrences of anxiety. The compositions can also be used to relieve the symptoms of various anxiety disorders including generalized anxiety, panic, acute traumatic stress disorder, post-traumatic stress disorder, phobias of various kinds including social phobia, compulsive disorders, and anxiety states related to withdrawal from drugs (e.g. alcohol, tobacco, and illicit drugs). The phrase “Echinacea” embraces Echinacea purpurea, Echinacea angustifolia, Echinacea pallida, or their combination. Echinacea preparations can be administered alone, but should preferably be used in combination with a vitamin mix (including but not limited to B1, B2, niacin, pantothenic acid, B6, biotin, folic acid B12, and/or C vitamin) and/or a mineral mix (including but not limited to calcium, magnesium and zinc).
Abstract: The invention relates to a method for accessing a slide from a plurality of digitized microscope slides from a remote workstation, wherein the plurality of digitized microscope slides are accessible via a plurality of data station units (DSU), the method comprising: providing a central management station unit (CMSU) connected to a communication network for storing slide information of the plurality of digitized microscope slides, allowing the workstation to connect to the CMSU via the communication network; providing at least a part of the slide information of the plurality of digitized microscope slides to the workstation; allowing the workstation to select a digitized microscope slide based on the provided slide information; and allowing for a direct connection over the communication network between the remote workstation and a DSU enabling access to the selected digitized microscope slide. The invention further relates to a system and a CMSU for carrying out the method.
