Abstract: Methods are provided for large scale purification of neurotrophins, including mature NGF, suitable for clinical use. The methods provide means to separate neurotrophins from various less desirable misprocessed, misfolded, size, glycosylated, or charge forms. Compositions of neurotrophins, including mature NGF, substantially free of these variants are also provided.

Abstract: Modifications in the sequence of Aequorea wild-type GFP provide products having markedly different excitation and emission spectra from corresponding products from wild-type GFP. In one class of modifications, the product derived from the modified GFP exhibits an alteration in the ratio of two main excitation peaks observed with the product derived from wild-type GFP. In another class, the product derived from the modified GFP fluoresces at a shorter wavelength than the corresponding product from wild-type GFP. In yet another class of modifications, the product derived from the modified GFP exhibits only a single excitation peak and enhanced emission relative to the product derived from wild-type GFP.

Abstract: The invention relates generally to methods of treating cancer and other diseases by modulating body temperature. Heat may directed to the hypothalamus of a warm-blooded animal to cool the animal, utilizing the physiological mechanisms that regulate body temperature to effect a compensatory cooling response, thereby lowering body temperature (hypothermia), and rendering other methods of lowering body temperature more effective. Heat may be withdrawn from the hypothalamus of an animal, cooling the hypothalamus, inducing a compensatory increase in body temperature (hyperthermia), and rendering other methods of raising body temperature more effective. Body temperature may be directly modulated by heat-exchange catheter positioned within a blood vessel of a patient.
Abstract: The invention relates generally to methods and apparatus for inducing hypothermia in an animal. Known methods for inducing hypothermia all involve cooling the outside or inside of an animal, sometimes in conjuction with drugs that disable the animal's homeostatic responses. The present invention is directed to a method and apparatus for applying heat to the hypothalamus of a warm-blooded animal in order to utilize the physiological mechanisms that regulate body temperature to effect a compensatory cooling response, thereby lowering body temperature. It is new and unsuggested in the art to apply heat in an effort to reduce body temperature.
