Title: Aspheric toric lens designs
Inventor: ROFFMAN JEFFREY H
IPC: G02C7/02
Filed: 1996-05-02
Granted: 2008-07-29
Abstract: Aspheric toric lens designs are disclosed which reduce the number of cylindrical axis locations required for stock keeping units in inventory by aspherizing the toric surface thereof. The present invention pertains to ophthalmic lenses, and in particular to contact lenses such as soft hydrogel contact lenses, particularly designed to fit astigmatic patients who are either non-presbyopic or presbyopic. One of the front and back surfaces of the aspheric toric lens defines a spherical surface corresponding at least to the patient's basic distance prescription Rx. The other of the front and back surfaces defines an aspheric toric curve, wherein the toric surface is constructed with aspheric radii, such that the aspheric curve desensitizes axial misalignment of the toric curve by providing an enhanced depth-of-focus. When the aspheric toric surface is on the back surface of the lens, the spherical curve on the front surface of the lens can comprise a single spherical curve corresponding to the patient's basic distance prescription Rx. When the aspheric toric curve is on the front surface of the lens, the spherical curve on the back surface of the lens can comprise a multifocus concentric annular ring spherical surface design.

Abstract: Procédés de modulation des réponses de lymphocytes T par manipulation des signaux intracellulaires associés à la costimulation des lymphocytes T. Les procédés consistent à inhiber ou stimuler la production dans un lymphocyte T d'au moins un D3-phosphoinositide. On peut manipuler la production de D3-phosphoinositides en mettant un lymphocyte T au contact d'un inhibiteur ou activateur de phosphatidylinositol-3-kinase. Les inhibiteurs de phosphatidylinositol-3-kinase utilisables dans ces procédés sont notamment la wortmannine et la quercétine, ou leurs dérivés ou analogues. Lesdits procédés peuvent également consister à moduler d'autres signaux intracellulaires associés à la costimulation, par exemple la phosphorylation de tyrosine protéique, par exemple par modulation de l'activité d'une tyrosine-kinase protéique ou d'une tyrosine-phosphatase protéique dans le lymphocyte T. L'inhibition d'une réponse de lymphocyte T conformément aux dits procédés trouve application sur le plan thérapeutique dans les cas où il serait souhaitable d'inhiber une réponse immunitaire dirigée contre un ou plusieurs antigènes, par exemple dans le cas d'une greffe d'organe ou de moelle osseuse et dans les maladies auto-immunes. Sinon, la stimulation d'une réponse de lymphocytes T conformément auxdits procédés trouve application sur le plan thérapeutique lorsqu'il s'agit d'améliorer une réponse immunitaire dirigée contre un ou plusieurs antigènes, et par exemple de stimuler une réponse antitumorale chez un sujet atteint d'une tumeur, de stimuler une réponse dirigée contre un agent pathogène ou d'augmenter l'efficacité d'un vaccin. On a également prévu de nouveaux dosages de dépistage pour l'identification d'inhibiteurs ou d'activateurs de phosphatidylinositol-3-kinase, que l'on peut utiliser pour inhiber ou stimuler une réponse de lymphocytes T.

Abstract: A pump (23) used to infuse a fluid into a patient (27) is controlled in accordance with a plurality of parameters entered by an operator. These parameters define a protocol that is applied in controlling the operation of the pump to determine the rate, volume, and timing of the fluid infusion. The operator enters the parameters using a keypad (16) in response to prompts provided on a display (18). Once the parameters for a current protocol are entered, they can be stored as a speed protocol by selecting that option from a menu appearing on the display. Up to three speed protocols can be stored in memory in the disclosed preferred embodiment. When preparing to infuse a medicinal fluid, an operator can elect to enter a new protocol or to select an appropriate speed protocol stored in memory for loading as the current protocol. Use of stored speed protocols saves time and reduces the likelihood of errors that can occur when data defining the parameters controlling the infusion process are entered by an operator.
