Abstract: The composition as described serves for in vivo cartilage repair. It basically consists of a naturally derived osteoinductive and/or chondroinductive mixture of factors (e.g., derived from bone) or of a synthetic mimic of such a mixture combined with a nanosphere delivery system. A  preferred mixture of factors is the combination of factors isolated from bone, known as BP and described by Poser and Benedict (WO 95/13767). The nanosphere delivery system consists of nanospheres defined as polymer particles of less than 1000 nm in diameter (whereby the majority of particles preferably ranges between 200-400 nm) in which nanospheres the combination of factors is encapsulated. The nanospheres are loaded with the mixture of factors in a weight ratio of 0.001 to 17 % (w/w), preferably of 1 to 4% (w/w) and have a release profile with an initial burst of 10 to 20 % of the total load over the first 24 hours and a long time release of at least 0.1 per day during at least seven following days. The nanospheres are composed of e.g.  ((D,L)-lactic acid/glycolic acid)-copolymer (PLGA). The loaded nanospheres are e.g.  made by phase inversion. The composition is advantageously utilized as a device comprising any biodegradable matrix in which the nanospheres loaded with the factor combination is contained.

Patent CA-2307774-A1 (CA)
Inventor: THOMSEN HENRIK
IPC: G01N21/359
Filed: 1998-10-30
Abstract: A cuvette for a spectrometric analysis instrument has two opposing windows (73, 76) made of a material, which is transparent to the light of the waveband used for the analysis. The windows define a limited light path of a light beam passing through a cavity inside the cuvette. When using cuvettes having windows of a material, such as diamond, having a refractive index considerably different from the fluid to be analysed, the window surfaces forming the cuvette cavity should not be parallel, thereby ensuring that the internal distances between opposed areas of the window surfaces will vary across the transparent windows. Thereby any internal reflections within the cavity will add in almost random phase, avoiding any tendency to resonance. This is very advantageous when the instrument is a member of a plurality of instruments, which must be standardised in order to be able to provide uniform calibrations for said plurality of instruments.

Title: Selective killing and diagnosis of p53+ neoplastic cells
Inventor: KIRN DAVID
IPC: A61K35/76
Filed: 1998-11-11
Abstract: Methods and compositions for treating and diagnosing neoplastic disease using viruses are provided. Preferably, mutant adenovirus lacking viral proteins which bind and/or inactivate p53 are administered to a patient having a neoplasm which comprises cells exhibiting p53 and lacking, or substantially devoid of mismatch repair activity. The mutant virus is able to substantially produce a replication phenotype in such neoplastic cells but is substantially unable to produce a replication phenotype in non-replicating, non-neoplastic cells having essentially normal p53 function. The preferential generation of a replication phenotype in neoplastic cells results in a preferential killing of the neoplastic cells, either directly or by expression of a cytotoxic gene in cells expressing a viral replication phenotype.

IPC: A01M7/00
Filed: 1998-12-08
Abstract: A method and device for discriminating different types of ground vegetation in agriculture is disclosed in which an artificial source (24) of electromagnetic radiation is employed for directing a beam (26) of radiation onto the vegetation. A sensor assembly (30) is provided for detecting reflected radiation from the vegetation in a selected frequency band and generating a sensing signal in response to the detection. A logic controller (32) determines whether a magnitude of the sensing signal falls within a predetermined range of values in order to distinguish one type of vegetation from another type. In the near infra-red region of the electromagnetic spectrum different types of weeds absorb significantly less infra-red radiation than other types of vegetation. Logic controller (32) compares the amplitude of the sensing signal with a decision window. If the amplitude of the incoming sensing signal falls within the decision window then the logic controller (32) determines that a certain type of plant has been detected and activates the corresponding solenoid valve (36) to deliver a dose of spray liquid from spray nozzle (14) to the targeted weed (28).
