Abstract:
The present invention provides surfactant compositions and associated methods and reagents, particularly useful for the treatment of dermatologic conditions. In some embodiments, provided compositions are formulated for and achieve transdermal delivery, for example by topical administration.
Abstract:
The embodiment described herein are related nanoemulsions comprising botulinum toxins. In one embodiment, the nanoemulsions are prepared by high pressure microfluidization and comprise a particle size distribution exclusively between 10 and 300 nm. The nanoemulsions contemplated by the present invention are useful for the cosmetic and medical treatment of muscular contracture states. For example, botulinum toxin may relax facial muscles such that skin wrinkles become smoother and less noticeable. Further, the present invention contemplates a cosmetic formulation that may be self-administered, for example, in the privacy of one's home and without medical supervision.
Abstract:
The present invention provides methods for assessing the activity of topically administered chemodenervating agents. In some embodiments, methods for assessing the activity of topically administered chemodenervating agents involve determining the extent of inhibition of acetylcholine release near the site of administration. In some embodiments, methods for assessing activity of topically administered chemodenervating agents involve observing a reflex motion of a limb of a subject.
Abstract:
The present invention relates to the use of stator windings of an induction machine to provide both rotation of the rotor and active rotor positioning within the stator frame by modification of the magnetizing current component in the D-Q plane of the rotor applied transformed to the AC waveform current of the stator windings according to an X-Y direction describing a rotor repositioning requirement.
Abstract:
In the present invention, several polyphase devices are connected together: an inverter, and electrical rotating machine, and a resistive load or braking resistor. The purpose of the resistive load is to dissipate excess electrical power which may be produced when the inverter acts to slow down the rotating machine, causing the rotating machine to act as a generator. In common art, this resistive load is a single DC resistor coupled to the DC link of the inverter via a separate resistor control transistor. In the present invention, the resistive load is a mesh connected array of resistors, and is electrically connected to the same inverter output terminals that the rotating machine is connected to. When it is desired that the resistors absorb energy, for example from a braking operation, then the harmonic content of the inverter output is adjusted, thus placing voltage differences across the resistor array and causing current to flow in the resistors.
