The present invention provides a novel radioactive compound for imaging malignant melanoma and a use thereof as a contrast agent for PET imaging.

Personal care compositions, such as oral care and skin care compositions comprising one or more coolants. The pleasant cool sensation provided by a coolant is enhanced in terms of quicker onset, greater intensity, impact or longer duration, which improves appeal and acceptability of the compositions to consumers. Also, a treatment for excess adipose tissue by applying an activating compound directly to a targeted area.
