We synthesized a molecule composed of two angiotensin II 4-8 pentapeptide fragments attached to a carrier molecule (TA), according to the template-assembled synthetic proteins concept. This molecule was investigated for receptor binding on angiotensin type ...
We quantified the effect of the excitatory amino acids kainate and glutamate on the uptake of cobalt in primary rat cerebellar granule neurons, by using inductively coupled plasma-atomic emission spectroscopy (ICP-AES). We quantitatively demonstrated that ...
We use the cathodoluminescence mode of a scanning electron microscope to investigate the depth and lateral dependencies of the electron-hole pairs generation by the electron beam in Al0.4Ga0.6As semiconducting material. A multiquantum well structure acts a ...
The analogous techniques of photoactivation of fluorescence (PAF) and fluorescence recovery after photobleaching (FRAP) have been applied previously to the study of actin dynamics in living cells. Traditionally, separate experiments estimate the mobility o ...
The time between i.v. injection of a glucose bolus and the time the glucose concn. peaked in the s.c. tissue was measured in pentobarbital-anesthetized rats with implanted 290-mm-diam. amperometric sensors. Boluses of 100, 200, and 400 mg/kg body wt. were ...
In a recent paper we measured the lateral hole diffusion in a GaAs/AlGaAs single quantum well (SQW) by a novel method. At helium temperature, we estimate a lateral hole diffusion length in the QW of 1.5 mum. However, the assumption that diffusion takes pla ...
The cathodoluminescence mode of the scanning electron microscope is used for the first time to investigate the lateral dependence of the electron-hole pair generation by the electron beam of the scanning electron microscope m semiconducting material. A mul ...
Cross-field transport of barium test ions is studied in a Q-machine plasma. Test particles are produced and tracked in their motion by an optical tagging method. The comparison between the measured tag signal and a simple theoretical simulation yields a qu ...
Theor. models for the action spectrum and the current-voltage characteristics of microporous (colloidal) semiconductor films in photoelectrochem. cells were derived. The derivation is based on the assumptions that the charge carrier transport in the semico ...
In a recent paper, we measured the hole diffusion length in a single quantum well (SQW) by a novel method using SEM-cathodoluminescence, assuming that the carriers diffuse only in the SQW. This assumption needs to be checked. Therefore, we present here a m ...
