In many biotechnological processes, living microorganisms are used as biocatalysts. Biochemical engineering science is becoming more aware that individual cells of an organism in a process can be fairly inhomogeneous regarding their properties and physiological status. Raman microspectroscopy is a novel approach to characterize such differentiated(More)
BACKGROUND In a subgroup of patients with chronic urticaria (CU) the disease is caused by pseudoallergic reactions to food. The aim of this study was to investigate whether disturbances of the gastrointestinal barrier function play a role in the pathomechanism of the disease. METHODS In 55 patients with CU gastrointestinal permeability was measured with(More)
The efficacy of 99mTc-labeled hematoporphyrin derivative in localizing neoplasms has been investigated with tumor-bearing animal models. Spontaneous mammary adenocarcinomas of outbred CFW strain Swiss-Webster white mice and chemical carcinogen induced breast tumors in female Sprague-Dawley white rats were clearly visualized in the scintigrams. Mice tissue(More)
A new experiment is described which generates flow in unmagnetized plasma. Confinement is provided by a cage of permanent magnets, arranged to form an axisymmetric, high-order, multipolar magnetic field. This field configuration-sometimes called a "magnetic bucket"-has a vanishingly small field in the core of the experiment. Toroidal rotation is driven by J(More)
A new concept for spinning unmagnetized plasma is demonstrated experimentally. Plasma is confined by an axisymmetric multicusp magnetic field and biased cathodes are used to drive currents and impart a torque in the magnetized edge. Measurements show that flow viscously couples momentum from the magnetized edge (where the plasma viscosity is small) into the(More)
The efficacy of 111In-labeled hematoporphyrin derivative (HPD) in localizing and detecting atheromas had been investigated with 10 atherogenic New Zealand white rabbits. Atherosclerotic plaques surgically induced in the abdominal aorta showed selective uptake of 111In-HPD over normal blood vessels averaging 0.01% ID/g tissue (range 0.003-0.023% ID/g).(More)
