  • Patent number: 9358239
    Abstract: The accumulation of abnormal proteins in neurodegenerative disorders is considered to induce oxidative stress and lead to cell death. Thus suppression of abnormal protein aggregation and reducing oxidative stress or reactive oxygen species (ROS) are expected to inhibit a wide range of harmful downstream events, providing an observation for identifying the potential prevention and treatment of neurodegenerative disorders comprising spinocerebellar ataxia (SCA), Alzheimer's disease (AD) or Parkinson's disease (PD). In the present invention, there are several cell and animal experiment models for SCA, AD and PD established, and NiSOD-like compounds were applied to these experiment models. The results have demonstrated how NiSOD-like compounds are likely to work in suppressing abnormal protein aggregation, recovering cell viability, increasing mature neuron number and neurite outgrowth length and protecting dopaminergic cells by reducing oxidative stress or reactive oxygen species in brain tissues.

  • Patent number: 9102261
    Abstract: A method, a system, and an apparatus used to automatically exchange identification and collision-related information utilizing wireless communication devices during vehicular accidents are presented. Upon collision, an impact sensor detects and registers the crash, causing a processor to trigger a collision warning, record selected identification and collision-related information in an electronic file, and exchange the same through a secure wireless connection with a collision-activated information exchange device (CIED) of the other vehicle involved and/or with an information exchange device (IED) or devices in the area of the collision. The stored electronic files can later be accessed by and/or even transmitted to authorities to serve as evidence in hit-and-run investigation and/or accident reconstruction.

  • Patent number: 8911597
    Abstract: A method of a preparing double-layer antimicrobial coating comprises: placing a plastic substrate into a PVD vacuum equipment for a vacuum process; rinsing and activating the substrate when the vacuum level reaches 10?2; coating a metal film onto the activated substrate by the vacuum process; spraying an antimicrobial intermediate coating onto the metal film; and then coating an antimicrobial metal film by PVD to obtain a double-layer antimicrobial layer. The coating has two antimicrobial layers, and includes bores because the density of the coated film layer produced by PVD is low, so that the antimicrobial agent of the antimicrobial intermediate coating can pass through the bores and move to the surface of the coating and the surface of the antimicrobial coating, so as to kill the bacteria or suppress their grown. The method is very suitable for the sanitary, electronics, electrical appliances and the automobile industry.
