Title: Improved polyvinylsiloxane impression material
Inventor: HARE ROBERT V
IPC: A61K6/90
Filed: 2000-03-08
Abstract: Improved two component polymerizable polyorganosiloxane compositions are described, particularly for use in making dental impressions, having improve d tear strength and wettability. Improved tear strength results from inclusion  of a quadri-functional polysiloxane having a vinyl content of 0.16 to 0.24 m - mole/g. Working time is maintained by including sufficient amounts of a retarder composition that delays onset of the vinyl polymerization. Wettability is improved by including a surfactant resulting in a surface contact angle with water at three minutes of less than 50~. The surfactant chosen has an HLB of 8-11, such that the wetting contact angle is achieved within less than two minutes and remains wetting throughout the working time  of the impression taking, substantially improving impression quality. A low viscosity impression material is provided and includes a base component and a catalyst component. Both components are siloxane-based materials.

Abstract: Known packages for topically applying flowable cosmetic composition and especially antiperspirant or deodorant compositions include roll-ons in which the applicator for the composition is presented to the skin along the longitudinal axis of the container, with its distributing head pointing along that same axis. In the present invention, when the invention package is employed, its applicator (13) is disposed along a second axis (6) which is at an acute angle to the principal axis (5) of the container, especially at a neck angle of from 12 to 30 degrees. Preferably the body (2) of the container is frusto-conical, with an outward-facing sidewall (89) aligning with the principal axis (5) and an inward-facing sidewall (86) aligning with the second axis (6). Users find it easier to apply the formulations topically, such as in the armpits, from a package which has inclined principal (5) and second (6) axis.

Title: Controlled electroporation and mass transfer across cell membranes
Inventor: RUBINSKY BORIS
IPC: C12N5/071
Filed: 2000-07-20
Abstract: Electroporation is performed in a controlled manner in either individual or multiple biological cells or biological tissue by monitoring the electrical impedance, defined herein as the ratio of current of voltage in the electroporation cell. The impedance detects the onset of electroporation in the biological cell(s), and this information is used to control the intensit y and duration of the voltage to assure that electroporation has occurred without destroying the cell(s). This is applicable to electroporation in general. In addition, a particular method and apparatus are disclosed in whi ch electroporation and/or mass transfer across a cell membrane are accomplished  by securing a cell across an opening in a barrier between two chambers such that the cell closes the opening. The barrier is either electrically insulating, impermeable to the solute, or both, depending on whether pore formation, diffusive transport of the solute across the membrane, or both ar e sought. Electroporation is achieved by applying a voltage between the two chambers, and diffusive transport is achieved either by a difference in solu te concentration between the liquids surrounding the cell and the cell interior  or by a differential in concentration between the two chambers themselves. Electric current and diffusive transport are restricted to a flow path that passes through the opening.

The copolymer composition was controlled by the monomer feed concentration to have between 7 and 71 mol% TFE. Additionally, new and predominantly linear co- and terpolymers were prepared by hydrolysis and trans-esterification of the latter copolymers. Furthermore, neither surfactants nor dispersing agents are required to produce the linear copolymers, but may be used.
