Peroxynitrite, a cytotoxic oxidant formed from nitric oxide (NO) and superoxide, induces DNA strand breakage, which activates the nuclear enzyme poly(ADPribose) synthase (PARS; EC 2.4.2.30). The cellular function of PARS was determined in fibroblast lines from PARS knockout animals (PARS2/2) and corresponding wild-type animals (PARS1/1), with the aid of the lipophilic PARS inhibitor 5-iodo-6-am...

OBJECTIVE To determine the most effective and biodegradable dispersant of spilled oil in water surrounding two Persian Gulf provinces. METHODS This study compared the effects of three dispersants, Pars 1, Pars 2, and Gamlen OD4000 on removal of oil in two Persian Gulf provinces' water. Overall, 16 stations were selected. Using the Well method, the growth rate of isolated bacteria and fungi wa...

The lunar semidiurnal influence is already known for tidal rivers. The moon also influences inland rivers at a monthly scale through precipitation. We show that, for some non-tidal rivers, with special geological conditions, the lunar semidiurnal tidal oscillation can be detected. The moon has semidiurnal tidal influence on groundwater, which will then export it to streamflow. Long time series ...

East Asian summer monsoon (EASM) precipitation received by northern China over the past 800 thousand years (ky) is characterized by dominant 100-ky periodicity, mainly attributed to CO2 and Northern Hemisphere insolation-driven ice sheet forcing. We established an EASM record in the Late Miocene from lacustrine sediments in the Qaidam Basin, northern China, which appears to exhibit a dominant 1...

When people engage with information, they are often in social groups. This applies, for example, in the case of museum visits, where people typically attend the museum and view the exhibits in small groups. This paper describes a proposed system GM, Group Modeller, which will create group models from a set of individual user models. We discuss the approaches and challenges in terms of common su...
