Abstract: An continuous dry powder inhaler arrangement is disclosed, the arrangement being provided with pre-metered doses of medication powder onto an exchangeable dose member like a cassette or the like for respiratory administration of medicaments into the deep or upper lung airways. The inhal er presents a device (8) with a case having a sliding lid (17), which can be se t in an open position exposing a mouthpiece (19). The arrangement further provides dose counters (18b/18c) and a cassette counter (34). In the state with open lid (17) the device is ready to deliver a prepared pre-metered dos e of medication powder upon an inhalation via the exposed mouthpiece (19). Medication drugs are in advance dosed as medication powder and carried by an  exchangeable dosing means. The exchangeable dosing member carries a number o f sequentially accessible doses, which are sealed to preserve a controlled storing of powder during the total lifetime of the dosing member. Upon an inhalation the cassette carrying a selected dose is released into a longitudinal motion by a forcing spring, whereby the protective foil is cut open to let a nozzle of a suction tube access the powder. By means of a braking arrangement the motion of the cassette is adjusted to such a speed that the time for a continuous delivery of the powder wil be time controlled  to an order of 0.5 to 5 seconds. The exchangeable dosing means presents a number of pre-metered doses of deposited dry medication powder.

Patent CA-2432415-A1 (CA)
Title: Acetyl-coenzyme a carboxylase 2 as a target in fat regulation and insulin action
Inventor: ABU-ELHEIGA LUTFI
IPC: A61P43/00
Filed: 2001-12-26
Abstract: The present invention highlights the role of acetyl-CoA carboxylase through its product malonyl-CoA in regulating fatty acid oxidation and synthesis, glucose metabolism and energy homeostasis. It discloses transgenic mice with inactivating mutations in the endogenous gene for the acetyl-CoA carboxylase 2 isoform of acetyl-CoA caboxylase. Inactivation of acetyl-CoA caroxylase 2 results in mice exhibiting a phenotype of reduced malonyl-CoA levels in skeletal muscle and heart, unrestricted fat oxidation, and reduced fat accumulation in the liver and fat storage cells. As a result, the mice consume more food but accumulate less fat and remain leaner than wild-type mice fed the same diet. These results demonstrate that inhibition of ACC2 acetyl-CoA  carboxylase could be used to regulate fat oxidation and accumulation for purposes of weight control. The instant invention provides a useful animal model to regulate malonyl-CoA production by ACC2 in the regulation of fatty acid oxidation by muscle, heart, liver and other tissues. They also identify potential inhibitors for studying the mechanisms of fat metabolism and weight control.

Title: Rendition style determination apparatus
Inventor: UMEYAMA YASUYUKI
IPC: G10H1/24
Filed: 2003-08-20
Abstract: There is provided a rendition style selector operable by a user to select a desired rendition style from among a plurality of rendition styles associated with a plurality of portions of tones. In response to selecting operation via the selector, a rendition style is determined which is to be applied to each desired portion of a tone. Then, performance information is output which designates a rendition style module corresponding to the determined rendition style. The module defines a waveform characteristic to provide the corresponding rendition style. According to another type of the rendition style selector, a user can collectively select a combination of a plurality of rendition styles associated with different portions of a tone. Thus, a plurality of rendition styles can be designated collectively by one selecting operation. Rendition style suitable for each portion of a tone to be generated may be determined on the basis of a performance event.

Abstract: A Cartesian loop system for radio transmitters in which at least part of the baseband processing is carried out in the digital domain. Digital processing circuitry (250) combines a baseband input signal with a Cartesian feedback signal (206, 207) to generate a forward signal. Analog circuitry (221, 201, 203, 204) converts the forward signal into a transmission output signal and generates the Cartesian feedback signal. Preferably the digital processing circuitry applies a phase shift process (208) to the Cartesian feedback signal before combination with the baseband input signal. The system is programmable allowing a single device to be used in a range of transmitters under different radio standards.
