Methods, apparatus, systems and machine readable medium for variable video production, distribution and presentation are disclosed. The external medical data telemetry device includes a processor, a reconfigurable radio-frequency transceiver circuit, at least one far-field antenna, and a user interface. The serial data interface provides access to retrieve the static unique identification number and sensed data measured with the at least one sensor from the memory. A standard point in the target scene is obtained according to the reference point and a specific depth corresponding to the reference point. , for pre-concentration and sample injection, and provides greater resolution of peaks for vapors within vapor mixtures, yielding detection levels that are 10-10,000 times better than direct sampling and analysis systems. These peptides alone or in combination are useful to treat cancer, and also in synergy with conventional therapies.
