We present a monolithically integrated vertical coupled cavity surface-emitting laser diode which exhibits stable laser emission at two design wavelengths simultaneously. The device consists of two slightly asymmetric coupled vertical cavities containing s ...
A method for treating a human amyloid disease which includes administering a pharmaceutically effective amount of a composition including an amyloidogenic protein-stabilizing aryl compound ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
Obesity is a disorder of energy balance, indicating a chronic disequilibrium between energy intake and expenditure. Recently, the mouse ob gene, and subsequently its human and rat homologues, have been cloned. The ob gene product, leptin, is expressed excl ...
The influence of the time interval between dye administration and detection by fluorescence microscopy was assessed in "early" squamous cell carcinomas of the cheek pouch mucosa and different healthy tissues of the Syrian hamster. Following intracardiac ...
