Abstract: The present invention relates to methods for assessing the risk of a patient for developing a potentially fatal cardiac dysrhythmia and for diagnosing Andersen's Syndrome. A tissue sample from a patient is obtained and the DNA or proteins of the sample isolated. From the DNA and protein isolates the sequence of the KCNJ2 gene or the Kir2.1 polypeptide can be obtained. The KCNJ2 gene or the Kir2.1 can be screened for alteration as compared to the wile-type sequence. An alteration in a copy of the KCNJ2 gene or a Kir2.1 polypeptide indicates that the patient has a high risk for developing a cardiac dysrhythmia and can be diagnosed with Andersen's Syndrome. The invention also related to isolated nucleic acid molecules with one or more alterations as compared to the wild-type sequence.

Abstract: A motor used to drive optical elements includes a stator, a rotor revolved relative to the stator, and a feedback apparatus used to sense the position of the rotor. The feedback apparatus is an encoder. The invention utilizes such described structure so as to eliminate the system's instability caused by the drift of the conventional capacitive type transducer or an inductance type transducer. Moreover, the response of the motor used to drive optical elements has been improved greatly by utilizing multipole motor.

Abstract: The invention relates to a compact transmitter optical sub-assembly (OSA), which can be used in small form factor optical transceivers. To limit back reflections from entering the laser cavity, the laser is disposed on a silicon optical bench (SiOB) at an acute angle to the longitudinal axis of the OSA. A portion of the light from the laser cavity passes through the back end of the laser cavity for measuring by a monitor photodiode. A rear beam steering lens redirects the portion of light into a v-groove in the SiOB and off of a reflective surface formed in the end thereof to the monitor photodiode, which is positioned face down over the v-groove.

Abstract: The present invention includes the disclosure of the hPER2 gene and a mutant of the hPER2 gene that participates in the human circadian biological clock. The product of the mutant hPER2 gene found in some familial advanced sleep phase syndrome patients is hypophosphorylated by casein kinase epsilon due to the serine-to-glycine mutation caused by the point mutation of the genomic sequence. Specifically, this serine-to-glycine mutation affects the casein kinase epsilon binding region of the hPER2 protein, thus blocking the phosphorylation cascade ordinarily caused by the binding of casein kinase epsilon to hPER2.
