  • Patent number: 8259470
    Abstract: A control circuit, a control method, and a power supply device are provided. The control circuit includes an obtaining sub-circuit, adapted to obtain a voltage signal from a reverse surge current when the reverse surge current appears on a primary side of a switch power circuit of a synchronous rectification circuit; a maintaining sub-circuit, adapted to continuously output a first control signal in a preset first time period when the voltage signal is greater than a preset first voltage threshold; and a control sub-circuit, adapted to control and switch off switch tubes of the secondary side of the switch power circuit of the synchronous rectification circuit according to the first control signal. Thus, a reverse current surge of the switch power circuit of the synchronous rectification circuit can be effectively suppressed, and the safety of a switch power supply of the synchronous rectification circuit can be effectively protected.

  • Publication number: 20110294794
    Abstract: Methods and pharmaceutical compositions comprising a low dose of a farnesyl transferase inhibitor useful in the treatment of proteinopathies are provided. These low doses are below the doses used in oncological treatments for which these compounds were initially designed. The treatment includes administering to a subject in need thereof a therapeutically effective amount of a farnesyl transferase inhibitor, wherein the amount is effective to inhibit the farnesylation of a non-Ras FTase substrate involved in the autophagy pathway without substantially affecting the farnesylation of Ras or other oncology related substrates. Treatments in accordance with the present invention may also include an acetylcholinesterase inhibitor, an activator of neurotrophic receptors, an NMDA anatagonist, an amyloid deposit inhibitor, an antipsychotic agent, an antidepressant, an anxiolytic, or an antioxidant.
