A paint bucket includes an upstanding continuous sidewall incorporating opposing sidewalls, and opposing front and rear walls. The methods exploit a recently-observed magneto-electric optical nonlinearity that produces intense magnetization in undoped, homogeneous dielectrics. Methods of using these compounds for modulation of Angiopoietin-2 expression and for diagnosis and treatment of disease associated with expression of Angiopoietin-2 are provided. The present invention also provides to a method of method for absorbing andor removing sebum andor styling product residue from the hair or scalp.
