The comet assay is a versatile assay for detecting DNA damage in eukaryotic cells. The assay can measure the levels of various types of damage, including DNA strand breaks, abasic sites and alkali-sensitive sites. Furthermore, the assay can also be modified to include purified DNA glycosylases so that alkylated and oxidized bases can be detected. The ...

Cu(I) from tetrakis(acetonitrile)copper(I) hexafluorophosphate ([Cu(MeCN)4]PF6) was complexed with five structurally related phosphines containing N-heterocycles. The interactions between the resulting complexes and some N-nitrosamines were studied using X-ray crystallography as well as emission spectroscopy. Upon complexation, three ...

DNA-methylating environmental carcinogens such as N-nitrosodimethylamine (NDMA) and certain alkylators used in chemotherapy form O6-methylguanine (m6G) as a functionally critical intermediate. NDMA ...

Aquatic eddy covariance (AEC) is an in situ technique for measuring fluxes in marine and freshwater systems based on the covariance of velocity and concentration measurements. Here, development of a fast multiple-channel sensor (FACT) enables the use of AEC for measurement of benthic fluxes of fluorescent dissolved organic material, salt, and heat at three distinct sites in Massachusetts, USA, including the ...

Abstract: Immune cells, such as macrophages and dendritic cells, can utilize podosomes, mechanosensitive actin-rich protrusions, to generate forces, migrate, and patrol for foreign antigens. Individual podosomes probe their microenvironment through periodic protrusion and retraction cycles (height ...

Abstract: Cancer metastasis involves the collective migration of cancer cells in confined space, a problem that has been widely investigated in vitro. Here, we quantify the flow patterns of cancer cell as they invade tissue space and deform ...
