Title: Amphotericin b/cholesterol sulfate composition and method
Inventor: ABRA ROBERT
IPC: A61K/
Filed: 1988-02-29
Granted: 1995-09-05
Abstract: An amphotericin B composition containing particles of amphotericin B and cholesterol sulfate, in a molar ratio of between about 1:1 to 1:4. The particles, when stored in lyophilized form and reconstituted in an aqueous suspension, have particle sizes predominantly between about 100-400 nm.  The composition formed at a molar ratio of about 1:1 amphotericin B:cholesterol sulfate has stable particle sizes in an aqueous suspension over a several-day storage period.  The composition is significantly less toxic and more effective in treating fungal infection than prior amphotericin B formulations.

Abstract: : Dispositif du type canon à eau pour produire dans l'eau des ondes acoustiques et se réarmer automatiquement après déclenchement. Un élément de contrôle comportant une tige, se déplace dans une cavité cylindrique sous l'action de deux forces antagonistes l'une étant créée par un ressort, l'autre par la pression d'un gaz dans un espace intermédiaire du dispositif et transmise par une canalisation. La chute de ladite pression au-dessous d'un certain seuil, interrompt la communication entre la canalisation et un canal relié à une vanne de commande et met celle-ci par un canal en communication avec une pression plus faible. Ceci permet d'éliminer certaines causes d'instabilité qui peuvent intervenir à l'usage dans les phases de réarmement du dispositif. Application à la prospection sismique par exemple.

Abstract: An aggregate of spherical fibres, particularly as filling material for blankets, such as quilts, pillows and the like ABSTRACT         An aggregate of spherical fibres, particularly for use as filling material for blankets, such as quilts, pillows or the like comprises fibres and/or threads that are wrapped spherically and essentially form a fibrous ball.  So that the properties of the aggregate of spherical fibres are better, particularly for use as filling material in blankets, such as quilts, pillows or the like, it is proposed that the fibrous balls contain a mixture of fibres, whereby one type of fibre has a higher modulus of elas-ticity compared to another type of fibre.  The fibres with the higher modulus of elasticity can also taper over their length.

The radioactive source is a tritium capsule (22) that interfaces with the receptor surface of the photovoltaic cell (12).  The capsule (22) has inside surfaces that are coated with a phosphor and is filled with tritium gas (26).  The tritium gas produces beta particles that bombard the phosphor (18) causing the phosphor to luminesce and produce photons. The photons, in turn, strike and cause the photovoltaic cell (12) to generate a current flow that is then applied, via a pair of electrodes (30),(32), to an external load. Also disclosed is a power pack (40) that houses a plurality of power modules (10).  The power pack includes provisions that allow the power modules (10) to be elec-trically interconnected to provide various series, parallel and series-parallel power output combinations.

Abstract: Tissue plasminogen activator (t-PA) zymogens and variants are prepared, including a fibrinolytically active variant of t-PA that has an amino acid alteration at a site within the protease domain of t-PA as compared with the corresponding wild-type t-PA, which alteration renders the variant zymogenic in the presence of plasmin-degraded fibrinogen, and/or fibrin (or plasma clot) specific, as compared to the corresponding wild-type t-PA. DNA sequences can be prepared that encode the zymogens and variants, as well as expression vectors incorporating the DNA sequences, and host cells transformed with the expression vectors. The zymogens and variants may be used in a pharmaceutical preparation to treat a vascular disease or condition or to prevent fibrin deposition or adhesion formation or reformation in mammals.

Abstract: ABSTRACT OF THE DISCLOSURE    A plastic dishwasher tub and support structure is disclosed.   A single piece is formed into a rear frame that attaches to the door frame of the dishwasher.   The rear frame is in an inverted U-shape with arms formed by bending a portion of the legs of the U out of the plane of the U. The bight of the U supports the rear of the tub while the arms attach to the door frame and serve as skids for the dishwasher.   The plastic tub is formed with integral reinforcing ribs on the tub bottom to bear against the rear frame.   In audition, retention blocks are cantilevered from the tub bottom to extend below the reinforcing ribs.   The bight of the rear frame slides into the space between the blocks and ribs during assembly and prevents up and down and fore and aft movement of the tub with respect to the frame.   Strips are placed on the jambs of the door frame astride the counterbalance levers on the door.   These strips limit the travel of the door in the open position. The door frame is formed from a U-shaped length of angle iron.   The door frame engages ribs integrally formed on the top and sites of the tub, parallel to the open front.
