The infrared emission of various comets can be matched within the framework that all comets are made of aggregated interstellar dust[ This is demonstrated by comparing results on Halley "a periodic comet#\ Borrelly "a Jupiter family short period comet#\ HaleÐ Bopp "a long period comet#\ and extra!solar comets in the b Pictoris disk[ Attempts have been made to generalize the chemical composition...

Crude oil is enriched in polycyclic aromatic hydrocarbons (PAHs). Many PAH analogs have proved to potentially damage DNA. DNA damage can be assessed using various biomarkers to find out the degree of genotoxicity of pollutants following in vitro exposure. In this research the comet assay and micronucleus (MN) test were used to detect DNA damages and cytogenetic changes following crude oil expos...

introduction: auger electron based radioimmunotherapy (rit) using 111in-dota-trastuzumab (111in-dota-antiher2) feasibility was studied in vitro on a her2/neu positive cell line, skbr3. methods:111in-dota-antiher2 was prepared according to the optimized conditions followed by quality control tests including radiochemical purity; immunoreactivity). skbr3 as a her2/neu positive cell line was used ...

Within the last decade, the comet assay has been used with increasing popularity to investigate the level of DNA damage in terms of strand breaks and alkaline labile sites in biomonitoring studies. The assay is easily performed on WBCs and has been included in a wide range of biomonitoring studies of occupational exposures encompassing styrene, vinyl chloride, 1,3-butadiene, pesticides, hair dy...

When environmental analysis is performed, the high number of samples required and handling conditions during the transport of these samples to the laboratory are common problems. The comet assay is a useful, highly sensitive tool in biomonitoring. Some studies in the literature aim to preserve slides in lysis solution for use in the comet assay. Until now, however, no efficient methodology for ...

Claudia Regina Bonini-Domingos Comet Assay is a technique which can detect single-strand breaks as initial DNA damage.(1,2) Cells submitted to electrophoresis under alkaline conditions in low melting point agarose gel show DNA damage in a comet-like form when viewed at fluorescence microscopy. The lesion from each cell is quantified according to the comet tail length as class 0, 1, 2 or 3.(3) I...
