The present invention relates to method for treating inflammatory bowel disease that includes administration of an effective amount of an antagonist of A2B adenosine receptors. In some situations, the techniques are used in conjunction with a fax delivery system to, as part of a connection established to perform a fax transmission, provide a variety of functionalities to a human recipient that is participating as part of the connection, such as when the human recipient is contacted in error. Indicia may be disposed along the base member and read using an electronic scanner that is coupled with a computer to track individual student attendance. Suitable materials include silicone rubber or other polymers or copolymers such as PTFE, FEP, Polyimide or blends with or without fillers or substrates. The probe includes a collapsibleexpandable structure that supports electrodes or other operative elements against the body tissue. A manufacturing method according to the invention for manufacturing a silicon carbide semiconductor device facilitates preventing defects from being causes in a silicon carbide semiconductor device during the manufacture thereof.
