Despite its relevance to the physiology of lymph formation and propulsion, the instantaneous flow velocity in single lymphatic capillaries has not been measured to date. The method of fluorescence recovery after photobleaching (FRAP) was adapted for this p ...
An apparatus is designed and realized to detect "early" cancer at the surface of the hollow organs in the human body by endoscopic means. The tumor is localized by the laser induced fluorescence of a dye (HPD) which concentrates selectively in the neoplast ...
Background. To optimize photodynamic therapy (PDT) and photodetection of cancer, two important variables that must be considered are the uptake of the dye and the dye contrast between normal and neoplastic tissue after injection. Methods. To study these va ...
Clinical results obtained endoscopically with an imaging fluorescence photodetection apparatus based on the use of one excitation wavelength and detection of the fluorescence emission performed in two separate spectral windows are presented. Early cancer p ...
Current therapy for several forms of anemia involves a weekly regime of multiple subcutaneous injections of recombinant human erythropoietin (hEpo). In an effort to provide a physiologically regulated administration of erythropoietin, we are developing cel ...
The paper describes gain measurements in InGaAs/InGaAsP multiquantum-well lasers at 1.55-mu-m derived from the spontaneous emission under current injection. The gain spectrum in a broad-area laser device is determined from the spontaneous emission spectrum ...
Treatment of C3H mice with partially purified or highly purified virus-induced interferon resulted in a marked increase in the expression of Fcgamma receptors (Fcgamma R) on splenic lymphocytes, mesenteric lymph node cells and thymocytes from cortisone-tre ...
