Portable radio frequency hyperthermia instrumentation. [For heating tumor tissues in situ]

Description: Portable radio frequency hyperthermia instrumentation has been constructed for application in the localized heating of human and animal tumors. Tissue temperature is regulated by electronic feedback techniques. Audible and visual monitoring of tissue temperature is provided.

Desferal (DFO) induced Ga-67 washout from normal tissue, tumor and abscess in experimental animals

Description: In the experimental animal, desferal (DFO) given intravenously washes out Ga-67 from all tissues. This effect is not uniform: blood activity is reduced very markedly, while liver activity is less affected. Maximal effect of DFO occurs if given close to the Ga-67 injection. When the time interval between the two is increased, the absolute amount of Ga-67 excreted in the urine in excess of the spontaneous excretion is reduced. Administration of DFO does not effect Ga-67 gastrointestinal excretion… more

Evaluation of energy spectral information in nuclear imaging and investigation of protein binding of cationic radionuclides by lactoferrin. Comprehensive progress report, October 1, 1977-September 30, 1980

Description: Construction of an Anger camera-computer system which allows collection of both the position and energy signals from events detected by the scintillation camera has been completed. The system allows correction of energy response non-uniformity of the detector and facilitates research related to effects of energy discrimination in radionuclide scintigraphy. The system consists of electronic hardware to transmit and digitize the energy signal, software to record and process that signal in conjunc… more

Physiopathology of blood platelets: a model system for studies of cell-to-cell interaction. Progress report, November 1, 1979-October 31, 1980

Description: This report covers the studies on basic mechanisms of cellular interactions, utilizing platelets as a model system and, when possible, concentrating on the influence that environmental factors (nutritional, metabolic, cellular, immunologic and others) have on them. The four major sections include: platelet interaction with tumor cells; a model for the study of cell-to-cell interaction; interaction of platelets with vessel walls; and platelet interactions with immune proteins.

(Accumulation of Methyl-Deficient Rat Liver Messenger Ribonucleic Acid on Ethionine Administration). Progress Report. [Methyltransferase Activity in Ehrlich Ascites Tumor Cells and Effects of Phorbol Ester on Methyltransferase Activity]

Description: Enzyme fractions were isolated from Ehrlich ascites cells which introduced methyl groups into methyl deficient rat liver mRNA and unmethylated vaccinia mRNA. The methyl groups were incorporated at the 5'; end into cap 1 structures by the viral enzyme, whereas both cap 0 and cap 1 structures were formed by the Ehrlich ascites cell enzymes. Preliminary results indicate the presence of adenine N/sup 6/-methyltransferase activity in Ehrlich ascites cells. These results indicate that mRNA deficient … more
