  • Publication number: 20120329045
    Abstract: A method of predicting the risk of a patient for developing phenytoin-induced adverse drug reactions (ADRs), including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), or drug reactions with eosinophilia and systemic symptoms (DRESS) is disclosed. Genetic polymorphisms of CYP2C genes (including CYP2C9, CYP2C19, CYP2C8 and CYP2C18), HLA alleles (including HLA-A*0207, HLA-A*2402, HLA-B*1301, HLA-B*1502, HLA-B*4001, HLA-B*4609, HLA-B*5101, HLA-DRB1*1001 or HLA-DRB1*1502) and phenytoin concentration in the patient's plasma can all contribute to phenytoin-induced ADRs.

  • Patent number: 8223071
    Abstract: A handheld electronic apparatus includes a positioning module, a sensing module, a constellation database, and a processing module. The positioning module generates location information associated with the handheld electronic apparatus according to a satellite signal received by the handheld electronic apparatus. The sensing module detects a vertical tilted angle and a horizontal observing direction associated with a positioned state of the handheld electronic apparatus. The processing module retrieves corresponding real-time constellation information from constellation data stored in the constellation database according to timing information, the location information, the vertical tilted angle, and the horizontal observing direction.

  • Publication number: 20120165357
    Abstract: The invention pertains to topical pharmaceutical formulations of berberine and its biologically equivalent analogues, such as palmatine and coptisine, for the treatment of rosacea and other red face-related skin disorders. The topical pharmaceutical formulations of this invention contain purified berberine as the primary active drug ingredient at concentrations higher than 0.1%. The invention also pertains to methods of treating rosacea and other red face related skin disorders, such as steroid-induced rosacea-like dermatitis, comprising the administration of topical pharmaceutical formulations that contain berberine or its biologically equivalent analogues, such as palmatine.

  • Publication number: 20120077192
    Abstract: The present invention provides a method of predicting the risk of a patient for developing adverse drug reactions, particularly SJS or TEN. It was discovered that an HLA-B allele, HLA-B* 1502, is associated with SJS/TEN that is induced by a variety of drugs. The correlation with HLA-B* 1502 is most significant for carbamazepine-induced SJS/TEN, wherein all the patients tested have the HLA-B* 1502 allele. In addition, another HLA-B allele, HLA-B*5801, is particularly associated with SJS/TEN induced by allopurinol. Milder cutaneous reactions, such as maculopapular rash, erythema multiforme (EM), urticaria, and fixed drug eruption, are particularly associated with a third allele, HLA-B *4601. For any of the alleles, genetic markers (e.g., HLA markers, microsatellite, or single nucleotide polymorphism markers) located between DRB1 and HLA-A region of the specific HLA-B haplotype can also be used for the test.

  • Publication number: 20090005977
    Abstract: A vehicle navigation system includes a GPS signal processor, an image processing module, a memory, a microprocessor, a navigation adjusting module, and a display module. The GPS signal processor receives GPS signals and obtains an unadjusted navigation position according to the GPS signals. The image processing module captures pictures of surrounding areas and acquires a reference position according to the pictures. The microprocessor calculates an offset between the reference position and the unadjusted navigation position and compares the offset with a predetermined offset. The navigation adjusting module adjusts the unadjusted navigation position according to the reference position and the offset comparison and displays a result on the display module.

  • Publication number: 20080153522
    Abstract: A message transaction method includes the steps of sending a connection request, receiving the connection request, generating a ringing response signal in response to the connection request, counting an elapsed time starting from generation of the ringing response signal, sending a disconnection request, stopping of the counting of the elapsed time upon detection of the disconnection request, comparing the elapsed time with at least one relation mapped by a lookup table, and providing a corresponding message in the matching relation. A system to implement the message transaction method is also disclosed.
