The present invention relates to an improved protective composition and method. This device allows a person to have a fragrance without having the fragrance coming into contact with the person’s skin or other clothing. An optimum switching response and hence an undistorted differential signal can be produced by virtue of the pull-up and pull-down transistors being in the form of PMOS transistors. Also, by inserting switching transistors corresponding to row selecting transistors, circuit symmetry of a differential amplifier circuit can be improved. The level of FSTL-1 protein present in the serum or synovial fluid of individuals suspected of having certain inflammatory disease is positively correlated with the severity of the disease. An access code request input requests, via the computer screen user interface, an access code for use by the authorized information seeker to access the remote database via the internet protocol connection.
