Patent CA-2284790-A1 (CA)
Inventor: WERENSKIOLD ANNE KATRIN
IPC: G01N33/574
Filed: 1998-03-20
Abstract: Especially nodal conditions and tumour size, histological type, degree of differentiation and receptor condition are used nowadays for the prognosis and further planning of patients with carcinoma of the breast. Emphasis is placed on evaluation of the condition of the axillary lymph node. Patients with a negative axillary lymph node condition generally receive no after-treatment, as their prognosis is better; yet 30 % of these patients suffer relapses. The method proposed by this invention should make it possible to determine the patient's risk of recividation. In accordance with the invention, the invention makes it possible to predict the further evolution of patients with carcinoma of the breast by means of a qualitative or quantitative determinatin of T1 protein and/or T1-mRNA is sample material taken from the patients.

Title: Conjugates of dithiocarbamates with pharmacologically active agents and uses therefor
Inventor: LAI CHING-SAN
IPC: C07C333/02
Filed: 1998-05-19
Abstract: In accordance with the present invention, there are provided conjugates of nitric oxide scavengers (e.g., dithiocarbamates, or "DC") and pharmacologically active agents (e.g., NSAIDs). Invention conjugates provide a new class of pharmacologically active agents (e.g., anti-inflammatory agents) which cause a much lower incidence of side-effects due to the protective effects imparted by modifying the pharmacologically active agents as described herein. In addition, invention conjugates are more effective than unmodified pharmacologically active agents because cells and tissues contacted by the pharmacologically active agent(s) are protected from the potentially damaging effects of nitric oxide overproduction induced thereby as a result of the co-production of nitric oxide scavenger (e.g., dithiocarbamate), in addition to free pharmacologically active agent, when invention conjugate is cleaved.

Title: Methods for treating neurological deficits
Inventor: REID JAMES STEVEN
IPC: A61P25/28
Filed: 1998-08-04
Abstract: The present invention features methods and compositions for treating a patient who has a neurological deficit. The method can be carried out, for example, by contacting (in vivo or in culture) a neural progenitor cell of the patient's central nervous system (CNS) with a polypeptide that binds the epidermal growth factor (EGF) receptor and directing progeny of the proliferating progenitor cells to migrate en masse to a region of the CNS in which they will reside and function in a manner sufficient to reduce the neurological deficit. The method may include a further step in which the progeny of the neural precursor cells are contacted with a compound that stimulates differentiation.

Patent CA-2308476-A1 (CA)
Inventor: BURSTYN HERSCHEL CLEMENT
IPC: G09G3/20
Filed: 1998-12-02
Abstract: L'invention porte sur de grands écrans constitués d'une série de petits écrans ou modules (110, 120, 130, 140, 210, 230, 310, 320, 330, 340, 712, 714), dont chacun affiche une partie de l'image à afficher et qui (110, 120, 130, 140, 210, 230, 310, 320, 330, 340, 712, 714), ensemble, affichent la totalité de l'image. A la différence des grands écrans usuels où l'on cherche nécessairement à réduire les bordures des petits écrans, de manière à atténuer les raccords entre les différentes parties de l'image, celui (100, 200, 300, 700) de l'invention projette des parties d'image balayées sur moins de la totalité de la surface des petits écrans (110, 120, 130, 140, 210, 230, 310, 320, 330, 340, 712, 714) et sur une surface telle que l'image se forme sur un panneau sensiblement plat (102, 202, 302, 710, 712, 830, 920, 1202) et sensiblement exempt de raccords visibles ou de discontinuités entre les parties d'image. Ainsi le grand écran de l'invention (100, 200, 300, 700) peut-il utiliser des éléments d'affichage (110, 120, 130, 140, 210, 230, 310, 320, 330, 340, 712, 714) sans bords étroits et non contigus pour créer des sous-images se recouvrant (602, 604, 606, 608). Ainsi les pixels d'image des parties qui constitueraient sinon des raccords ou des discontinuités créés à partir des données d'image apparaissent à l'endroit voulu avec la luminosité voulue dans l'image (600) et notamment dans les zones de recouvrement (248, 312, 322, 718) des sous-images se recouvrant (111', 112', 113', 121', 122', 123', 310', 1211', 1213', 716, 602, 604, 606, 608). Lorsque les faisceaux de balayage sont électroniques, (424, 426), le panneau plat consiste en une façade (302) de luminophores (372, 374, 376) excités par le faisceau (424, 426) pour produire de la lumière. Lorsque les faisceaux de balayage sont des rayons lumineux, (114, 115, 116, 124, 125, 126, 222, 224, 226, 242, 244, 246, 1214, 1216, 822), le panneau plat constitue un distributeur de lumière, par exemple un panneau diffuseur (102, 202, 710).

Title: Improvements in mattresses or cushions
Inventor: CUEREL PHILIPPE
IPC: A47C27/08
Filed: 2000-05-19
Abstract: A mattress is provided with a plurality of inflatable cushion elements each having two cushion chambers. Air or filling pressure medium can be regulated by a device with a pump. The pump is coupled to a control in which filling pressure values and/or arithmetical operations are programmed. The pump is also provided with sensors. This enables the filling pressure to be increased or reduced on the basis of the weight of a lying person loading the cushion elements until a predetermined value corresponding to a specific degree of hardness or comfort for lying is attained. Simple pressure on a key on a remote control is therefore sufficient to bring about completely automatic adaptation to the lying person, regardless of whether he or she weighs 40 or 150 kg. This intelligent mattress offers an absolute maximum of individual comfort for lying with a minimum of effort for operation.
