First text data relating to audio data and being non-copyrighted, a flag representing that the first text data are non-copyrighted, an information piece representing a character code used for the first text data, and an information piece representing a size of the first text data are formed into a first text block. A composition containing medium-chain fatty acids, such as Capri acid or caprylic acid, or salts or triglycerides thereof, or mono- or diglycerides or other analogues thereof or medium-chain triglycerides is administered to a human or animal needing treatment in an amount sufficient to reduce or eliminate neutropenia. The filter is arranged in the channel remotely from the at least one transducer and the channel defines a flow path for the fluid sample such that the fluid sample contacts a first transducer to generate a first signal, followed by the filter, followed by the first transducer or a second transducer to generate a second signal. In another exemplary embodiment, a programmable security circuit also stores a set of authorized operation security keys. The liquid droplet introducing tank 3A enables liquid droplets to be suitably injected therein and is suitable for reducing size. Preferred embodiments of the blocking molecule have sequences complimentary at least partially to the unwanted sequence.
