Abstract: In order to reduce blood flow thereby accumulating additional equivalent thermal dose following the step of heating an organ or appendage by irradiating microwaves at the organ or appendage, the step of compressing the organ or aplpendage following the heating step is added to thertherapy treatment. In a preferred embodiment, the organ is the prostate and periodic prostate compression is employed to reduce the prostate blood flow thereby allowing chemotherapy, thermosensitive liposome-encapsulated chemotherapy, or gene therapy to accumulate in the prostate region during thermotherapy.  Doppler ultrasound imaging may be used to measure tumor blood flow rate and then serve as real-time feedback to assist in adjusting the amount of balloon catheter inflation and to assess damage to the tumor vasculature during the treatment.

Abstract: Dans le domaine des soins de santé, il existe plusieurs aides techniques qui facilitent les transferts ( lever les patients du lit ou du fauteuil) ou encore la rééducation à la marche, en particulier en ce qui concerne les soins aux personnes âgées. Parmi ces aides techniques, il y a une panoplie de ceintures qui ont pour but d'aider les intervenants de la santé à transférer et faire marcher les patients en perte d'autonomie. Cependant, les ceintures qui sont sur le marc hé sont instables et très peu fiables sur le plan de la sécurité. En effet, aucune ne possède de mécanisme qui l'empêche de glisser vers le haut lors de l'exécution du transfert ou pendan t la rééducation à la marche. L'originalité de cette invention est que cette ceinture est munie de deux courroies qui passent sous le siège de la personne, ce qui l'empêche de glisser vers le ha ut et ce qui assure une prise ferme et sécuritaire pour les intervenants de la santé. Elle est destinée aux patients en lourde perte d'autonomie. Elle s'installe facilement en position couchée ou assise. Elle assure une exécution sécuritaire des transferts suivants : se lever du lit et se lever du fauteuil. Elle s'avère aussi une aide précieuse lors de l'entraînement à la marche. Sur le plan biomécanique, elle offre aux intervenants un appui solide au niveau des tubérosités ischiatiques (région inférieure du bassin) et diminue ainsi le risque de blessures au travail. Finalement, elle est beaucoup moins coûteuse que plusieurs aides techniques disponibles actuellement sur le marché et est plus versatile que les lève-personnes.

Title: Portable breathing apparatus
Inventor: SEONG SAE-JAE
IPC: A62B7/02
Filed: 2005-03-18
Abstract: Disclosed is a portable breathing apparatus. The portable breathing apparatus according to the present invention comprises: an air tank 10 chargeable with air at the predetermined pressure and portable; a pressure valve member bypassing one portion of air when the pressure of air supplied from the air tank 10 falls less than certain pressure; a regulator valve member 30 converting air induced from the pressure valve member 20 into breathable pressure, thereby regularly supplying the converted air to a mouth 31; a pressure switching member 40 enabling electric power to be switched on/off by compressed air, induced and bypassed from the pressure valve member 20; and a vibration means 50, contactable to a human body, generating vibration at the same time when the electric power of the pressure switching member 40 is switched on, thereby warning lack of compressed air.  Thus, the present invention may reduce casualties by timely informing an operator of the time when the carrying air tank 10 is to be supplemented while operating at a crisis and very hectic site such as diving or the fire, and at the same if necessary, to enable the operator to ask for help to another person nearby.
Patent CA-2502647-A1 (CA)
Title: Methods for crystallographic structure determination employing hydrogen exchange analysis
Inventor: WOODS VIRGIL L JR
IPC: G06F19/00
Filed: 2003-10-17
Abstract: The present invention provides methods for crystallographic structure determination employing hydrogen exchange analysis. Hydrogen exchange analysis is used to identify unstructured regions of a protein, which are then deleted to obtain one or more modified proteins for crystallization and structure determination. Optionally, an initial hydrogen exchange stability map of a protein is compared to that of at least one modified form of the protein to identify unstructured regions, while retaining characteristic structure of the native protein. Hydrogen exchange analysis is performed by determining the quantity of isotope and/or rate of exchange of peptide amide hydrogen(s) with isotope on a labeled protein. Proteins with fewer unstructured regions, and thus improved hydrogen exchange structural maps, are optimal for high quality crystallization and structure determination.

Title: Animal waste effluent treatment
Inventor: SHEETS RICHARD G SR
IPC: C02F1/78
Filed: 2003-11-25
Abstract: Animal waste such as fecal material from swine, chicken, turkey, and cattle is converted into useful forms such as fertilizer, other types of soil builders , and even nutrient feed additives. Devices, systems, and methods are provided that allow economical conversion and in many instances, alleviate the production and release of undesirable gases such as sulfide and ammonia. In one embodiment, undesirable anaerobic and facultative anaerobic bacteria are killed at a greater rate than desirable soil compatible aerobic bacteria. Th e use of low temperature killing diminishes off gassing commonly associated wi th other techniques, and the use of gas trapping additives such as zeolites provides enhanced soil building qualities such as slow release of nitrogen a nd slow release of moisture to soil. The methods allow convenient adjustment of composition, allowing conversion of waste into tailored designer fertilizer suited for particular soils. Other embodiments provide other soil building qualities as well as nutrient qualities for feedstock used in animal husband ry such as aquaculture.

Abstract: Pilot signal transmission sequences and methods are described for use in a multi-sector cell. Pilots in different sectors are transmitted at different known power levels. In adjacent sectors a pilot is transmitted while no pilot is transmitted in the adjoining sector. This represents transmission of a NULL  pilot signal. A cell NULL is also supported in which NULL pilots are transmitted in each sector of a cell at the same time. Multiple pilot signal measurements are made. At least two channel quality indicator values are generated from measurements corresponding to at least two pilot signals of different power levels. The two values are transmitted back to the base station which uses both values to determine the transmit power required to achieve a desired SNR at the wireless terminal. The wireless terminal also reports information indicating its location to a sector boundary.
