IPC: C12Q1/24
Filed: 2001-02-06
Abstract: Devices for culturing microorganisms include a container and within the container an immobilization layer made of an interconnected network of polym er chains. The interstitial spaces between the interconnected polymer chains ar e of a size on average less than an average size of microorganisms to be cultured such that substantially all of the microorganisms in a sample durin g culturing are immobilized on the surface of the immobilization lawyer. Relat ed methods for detecting microorganisms include providing a device as described  above and adding a fluid sample to the device. The fluid sample potentially contains microorganisms and is of a volume of at least .04 ml per each squar e centimeter of surface area of the immobilization layer. The method then allo ws the fluid sample to be completely absorbed and immobilized within the immobilization layer, while substantially all microorganisms present within the fluid sample are immobilized on a top surface of the immobilization laye r. The device with the fluid sample can be incubated for a period of time so as  to allow for growth of any microorganisms present. The method then can detec t any microorganisms present on the immobilization layer.

Patent CA-2404877-A1 (CA)
Inventor: OBLACK MARK
IPC: A01K15/02
Filed: 2002-09-25
Abstract: A flying toy having a resilient, non-circular frame substantially radiated about an imaginary center axis. The fame includes a plurality of elongated side members substantially interconnected by a plurality of radially-extending feet members, where a higher concentration of the weight of the frame resides at its periphery. Each side member is arced inward toward the imaginary center axis. The frame defines a central opening of which the imaginary axis is axially aligned. A flexible membrane is attached to least a portion of the side members and substantially covers the central opening. In one embodiment, a center portion of each side member is positioned above its adjacent feet members when the toy is in an at rest position to form a structure that is substantially concave in shape in the at rest state. During spinning flight, the higher concentration of weight at the periphery induces centrifugal force upon the toy causing the side members to partially flatten out. When the toy lands, it lands upright and reverts to its at rest position.

Abstract: Pour produire par synthèse le dérivé benzophénone de combretastatine A-1 appelé "hydroxyphenstatine", on a couplé un bromobenzène protégé et un benzaldéhyde pour former un benzhydrol qui a ensuite été oxydé en cétone. L'hydroxyphenstatine a été transformée en un promédicament au phosphate de sodium par une phosphorylation au dibenzyl phosphite suivie d'un clivage du benzyle. On a remarqué que l'hydroxyphenstatine et les promédicaments issus de cette dernière sont un inhibiteur puissant de la polymérisation de la tubuline et présentent une activité antinéoplastique étonnamment efficace contre une série de cellules cancéreuses humaines et de cellules leucémiques lymphocytiques P388 de souris.

Abstract: A system and method for synchronizing a set of nodes connected to a central switch in a multi-node data processing system, such as a NUMA data processing system, are disclosed. Initially, time base register values are retrieved from each of the set of nodes. A common time base register value is then determined based upon the time base register values received from the nodes. The common time base register value that is determined is then broadcast to each of the nodes. Prior to reading the time base register values, packet traffic among the set of nodes may be halted by broadcasting a halt traffic packet to each of the nodes. In this embodiment, normal packet traffic may be resumed after synchronization by broadcasting a resume traffic packet to each of the nodes.

IPC: A61B17/00
Filed: 2002-01-18
Abstract: The present invention relates to methodology of an apparatus for accurately positioning devices for performing endoscopic cannulation, papillotomy and sphincterotomy and similar procedures. The sphincterotome with a steerable or adjustable distal segment of the present invention allows the physician to control the position of the distal tip of the device independently of the endoscope and adjust for inconsistencies in the device and the anatomy.  According to one embodiment of the present invention, a threaded portion of a cable assembly cooperates with a torque transmission element and a cog to enable the operator to rotate a cutting wire into a desired position relative to the catheter. Alternate embodiments allow the operator to fix the depth of a needle knife while allowing, if desired, accurate rotational positioning of the associated catheter. Threaded stabilizing elements, pivot elements and a steering wire may be used together or individually to accomplish these features. Presently available products that may be modified according to the present invention include, but are not limited to, Boston Scientific Sphincterotomes and Needle Knives.

Title: Tertiary perfluorocycloamines as a basis for gas transport emulsions and process for preparing thereof
Inventor: IVANITSKY GENRIKH ROMANOVICH
IPC: A61K31/13
Filed: 2000-12-29
Abstract: The inventive perfluoronated cycle-containing tertiary amines (PFCTA) of general formula (1) where n=1 or 2; m=2 or 3 X represents or , at n=2 X  represents are used as a basis for gas conveying emulsions. PFCTA is a group of compounds near to perfluor-N-(4-methylcyclohexyl)-piperidine with respect to the properties thereof, in particular with respect to a critical solution temperature in hexane. Said compounds are used in a mixture, thereby producing a range of compounds which exhibit gradually changing characteristics and making it possible to obtain highly uniform fluorocarbon phases of the emulsions and to increase the stability of emulsion particles which are stabilised with the aid of ethylene oxide-propylene oxide block polymers without being toxic for small and large animals. The PFCTA is produced by electrochemical fluorination of n-piperidine heptane fluor toluene in anhydrous hydrogen fluoride. The use of said PFCTA mixture instead of the individual perfluor-N-(4-methylcyclohexyl)-piperidine makes it possible to simplify, accelerate and lower the price of the production of perfluoronated organic compounds and extend the use of gas conveying emulsions produced on the basis thereof.
