The invention relates to pyridines and uses thereof, including to inhibit lysophosphatidic acid acyltransferase \u03b2 activity andor proliferation of cells such as tumor cells. The method includes generating a carrier signal and modulating the carrier signal to communicate the sensor data and wirelessly transmitting from the stylus to the device the carrier signal as modulated through the touch sensor of the device. According to the invention, it is possible to form a recess that opens only toward the outer surface of the peripheral wall of the base of the case, without disposing undercuts in the base. The Web services network architecture and integrated publicationsubscription system according to the present invention can be implemented across any suitable computer network, including a local area network, an intranet or the Internet.
