  • Publication number: 20200101025
    Abstract: The present invention relates to transdermal delivery systems, methods and kits that include an agent to penetrate the basement membrane, a membrane of the skin previously known to be difficult to penetrate. In particular, the formulation includes a basement membrane disruptor that reversibly denatures the basement membrane of the skin. The formulation of the present invention further includes having at least one penetration agent, at least one vaso-modulator, and at least one active ingredient. In an embodiment, the penetration agent includes a solvent, a lipophilic agent, a hydrophilic agent, wherein the basement membrane disruptor, the vaso-modulator, and the active ingredient pass through the stratum corneum and epidermis. The basement membrane disruptor allows the vaso-modulator and the active ingredient pass through the basement membrane to dermis. The active ingredient, once at the dermis, is delivered locally to the tissue or systemically to the blood stream.

  • Publication number: 20200009095
    Abstract: Set forth herein is a preparation of ibuprofen (2-(4-isobutylphenyl) propionic acid) in the free acid form that is suitable for topical administration. The topical ibuprofen formulation is prepared by dissolving the free acid form of ibuprofen, or preparing a homogeneous suspension of the free acid form of ibuprofen, in the presence of a pharmaceutically acceptable solvent so as to produce a topical drug formulation compatible with the penetration of 2-(4-isobutylphenyl) propionic acid through the skin tissue. Topical formulations of ibuprofen can be based on a pharmaceutically acceptable solvent such as, e.g., a pyrrolidone solvent or dimethylacetamide.

  • Patent number: 10360004
    Abstract: A system, method and computer program product to refine an original complex CFG into a simpler CFG showing interesting paths and reducing interfering paths with dynamic input for the state of program. The method receives/encodes dynamic user input in the form of annotations which encodes user's special interests or knowledge of the program at run time, e.g., some assumptions of any variables appeared, which can be equations of variable and value or relationships between variables. The method then simplifies all the branching points in a generated AST (Abstract Syntax Tree) whenever possible by querying a SMT (Satisfiability Modulo Theories) solver with branching condition and the user annotations and by evaluating immediate values of expressions or eliminate unreachable parts in the CFG. Finally, the method generates a simplified CFG by simplified AST. This can assist a programmer to understand the code and facilitates correlating different basic blocks under a same scenario.

The PWM controller outputs a PWM control signal and the reference voltage under the control of the PWM turn-off signal and a state control signal, wherein the state control signal controls the state of the PWM control signal. The state detector detects a state change in the PWM control signal or an equivalent signal for the PWM control signal, and outputs a state input signal. The state machine produces a plurality of states according to the state input signal, and outputs the state control signal reflecting the plurality of states.
