Title: Resource reservation
Inventor: ERIKSSON ANDERS
IPC: H04L47/80
Filed: 1998-07-01
Abstract: A method is provided for achieving admission control to a public connectionless packet network. This provides a method of access control which allows service differentiation in a form which permits a user to receive a quality of service guarantee which is better than a "best effort" service. Each transmission by a user across the network includes a message sent to the user from the network. The message includes information about the priority level of the transmission, based on the user's contract with the network provider, and can subsequently be extracted by the network to determine how to handle the transmission, and to determine the resources available for future transmission requests.

Abstract: L'invention concerne une protéine présentant une activité canonique de synthétase D'ARNt de lysyle, purifié dans Methanococcus maripaludis, cloné et séquencé. La séquence d'acide aminé expérimentale de l'enzyme indique un nouveau polypeptide de classe I sans apparentement structurel à la synthétase d'ARNt de lysyle de classe II signalée dans les eubactéries, dans les eucaryotes et dans le Crenarchaéote Sulfobus solfataricus. Un polypeptide de classe I similaire a été isolé dans Borrélia burgdorferi, l'agent responsable de la maladie de Lyme, et un cadre de lecture ouvert codant pour une synthétase d'ARNt de lysyle de classe I a été identifié dans le génome de Treponema pallidum, l'agent responsable de la syphillis. Le gène B. burgdorferi codant pour ARNtLys1 a été cloné et utilisé pour préparer de l'ARNt in vitro. La différence fondamentale entre le pathogène et l'hôte dans un enzyme essentiel suggère que la synthétase d'ARNt de lysyle de classe I peut constituer une cible pour la mise au point de médicaments et de diagnostics médicaux et vétérinaires pour Borrelia et d'autres infections à micro-organismes.

IPC: A22B5/06
Filed: 2000-08-09
Abstract: La chasse aux grands gibiers sauvages (orignal, caribou, cerf, ours) est un sport noble et qui de plus permet à l'adepte de ce sport de déguster une viande de haute qualité. Pour que cette viande garde son bon goût, il est impératif de prendre des précautions particulières dans les heures qui suivent l'abattage puisque cette période e st déterminante pour sa conservation. Il est particulièrement important d'éviscérer rapidement l'animal, le couper  en quartiers et les suspendre afin que le sang s'égoutte et que la viande refroidisse. Il  est aussi essentiel qu'elle soit protégée contre toute contamination par les insectes. Comme ces animaux sont abattus dans toutes sortes de conditions de terrain, il devient parfois difficile pour le ou les chasseurs de transporter rapidement la carcasse à un endroit ou la viande peut être réfrigérée. Ils doivent donc, soit la laisser sur les lieux d'abattage ou la transporter  au camp de chasse. Il s'écoule souvent entre 2 et 5 jours avant qu'elle soit définitivement dépecée par un boucher. L'invention qui est revendiquée se compose de deux éléments, soit un support  composé d'une barre horizontale et de pattes télescopiques qui permettent de suspend re les parties de gibier. Le tout leur permet de refroidir rapidement et de s'égoutter de leur  sang. L'autre partiecomprend un filet qui entoure la viande, permet une circ ulation d'air et empêche l'intrusion d'insectes. Ces deux éléments sont démontables et légers. Ils peuvent donc être transportés facilement sur les lieux de chasse et assemblés rapidement. Ils peuvent auss i demeurer au camp de base. Le filet peut être aussi utilisé individuellement sans le support de métal. Dans les endroits difficilement accessibles, on peut utiliser un arbre comme support horizonta l.

Title: Toluidine blue-based photodynamic therapy for inducing apoptosis in activated t-lymphocytes, and consequently for treating psoriasis and for bone marrow purging
Inventor: TREMBLAY JEAN-FRANCOIS
IPC: A61K41/00
Filed: 2001-01-12
Abstract: Photodynamic therapy is a new therapeutic modality in dermatology involving the administration of a photosensitizer and its subsequent activation with visible light to destroy or alter the function of target cells or tissues. Toluidine blue i(TBO) is a non-toxic cationic dye of the phenothiazine family. We show that toluidine blue has potent phototoxic effect against malignant human T lymphocytes in vitro.      Apoptosis (DNA fragmentation and cell death) was rapidly induced by TBO in Jurkat cells. Psoriasis is an inflammatory skin disease in which the role of T lymphocytes is well established. Extensive psoriasis could be an ideal indication for photodynamic therapy with whole body light exposure after systemic photosensitizer administration. The use of human psoriatic skin-grafted SCID mice has been proven useful and reliable in the study of novel therapeutic agents. The goal of this project is two-fold: 1) to determine the dose-range of systemically administered toluidine blue and light inducing a phototoxic reaction in mice 2) determine whether we can induce clinical remission or improvement using TBO-based PDT in SCID mice. Mice are administered TBO and irradiated with light. Psoriatic skin response to treatment is followed with serial clinical assessments. A dose in the µg range of TBO is to be administered systemically to psoriatic patients. Further, the potent apoptotic effect of TBO on activated lymphocytes T is indicative of a role of TBO for bone marrow purging. A concentration in the µmolar range of TBO is to be contacted with bone marrow cells.
