A Laser Microbeam Implemented at the Heavy-Ion Microbeam Facility
The heavy-ion microbeam is used for targeted irradiation of living cells (in culture) with ions from the UNILAC linear accelerator of GSI [1]. A custom-made epifluorescence microscope is available for beam targeting as well as for observation of proteins (tagged by fluorescent dyes) in sub-compartments of interest. In order to gain better insight into DNA damage repair processes, we intend to e...
متن کاملMicrobeam-coupled capillary electrophoresis.
Within the first few microseconds following a charged particle traversal of a cell, numerous oxygen and nitrogen radicals are formed along the track. Presented here is a method, using capillary electrophoresis, for simultaneous measurement, within an individual cell, of specific reactive oxygen species, such as the superoxide radical ([Formula: see text]) as well as the native and oxidised form...
متن کاملSmithsonian Microbeam Standards
This is a short history of the Smithsonian Microbeam Standards; their sources, selection, preparation, and analyses. Fifty-eight minerals, natural glasses, and synthetic samples have been characterized in the past 25 years. During that time, over 750 requests were received for approximately 11 000 individual samples. These reference samples are referred to as the Smithsonian Microbeam Standards.
متن کاملUltraviolet microbeam irradiation
Marginal bands were isolated from newt red blood cells and, using monochromatic light from an ultraviolet microbeam, the marginal band microtubules were irradiated in vitro to produce areas of reduced birefringence (ARBs). The ARBs neither moved nor changed shape after they were formed, though the marginal bands sometimes changed shape during the irradiation. Marginal band ARBs 'were regions in...
متن کاملMicrobeam radiation therapy.
It is proposed to carry out radiotherapy and radiosurgery for brain lesions by crossfiring an array of parallel, closely spaced microbeams of synchrotron-generated x rays several times through an isocentric target, each microbeam in the array having an approximately 25-microns-wide adjustable-height rectangular cross section. The following inferences from the known tissue sparing of 22-MeV deut...
