Increased river loads are projected as one of the major consequences of climate change in the northern hemisphere, leading to elevated inputs of riverine dissolved organic matter (DOM) and inorganic nutrients to coastal ecosystems. The objective of this study was to investigate the effects of elevated DOM on a coastal pelagic food web from the coastal northern Baltic Sea, in a 32-day mesocosm e...

Many WWW applications generate HTML or XML documents dynamically. Current tools, however, like languages using DOM or JAVA Server Pages do not allow to check the validity of the generated documents statically. Instead, validity has to be “checked” dynamically by appropriate test runs. This paper addresses this problem by introducing a new distinct class for each element type of a DTD. Each clas...

This investigation into the occurrence, character, and transformation of dissolved organic matter (DOM) in treatment wetlands in the western United States shows that (i) the nature of DOM in the source water has a major influence on transformations that occur during treatment, (ii) the climate factors have a secondary effect on transformations, (iii) the wetlands receiving treated wastewater ca...

Marine dissolved organic matter (DOM) is one of the largest reservoirs of reduced carbon on Earth. In the dark ocean (4200m), most of this carbon is refractory DOM. This refractory DOM, largely produced during microbial mineralization of organic matter, includes humic-like substances generated in situ and detectable by fluorescence spectroscopy. Here we show two ubiquitous humic-like fluorophor...

Methylmercury (MeHg) is the only species of mercury (Hg) to biomagnify in aquatic food-webs to levels that are a widespread concern for human and ecological health. Here we investigate the association between dissolved organic matter (DOM) in seawater and Hg speciation and uptake using experimental data and field measurements from Long Island Sound (LIS) and the Northwestern Atlantic continenta...

Among the early events in herpes simplex virus 1 replication are localization of ICP0 in ND10 bodies and accumulation of viral DNA-protein complexes in structures abutting ND10. ICP0 degrades components of ND10 and blocks silencing of viral DNA, achieving the latter by dislodging HDAC1 or -2 from the lysine-specific demethylase 1 (LSD1)/CoREST/REST repressor complex. The role of this process is...

objective(s):sea cucumber is one of the classes of echinoderms, which is considered as a health marine product and possess various biological characteristics with therapeutic application. the present investigation attempted to evaluate the potential of anti-cancer persian gulf sea cucumber species holothuria arenicola (h. arenicola) aqueous extract on mice colon carcinoma cells in vitro and in ...

Marine dissolved organic matter (DOM) is a key source of carbon and nutrients to microbial life in the oceans, but rapid biological utilization of labile DOM confounds its compositional characterization. In order to characterize potentially bioavailable DOM produced by phytoplankton, DOM from axenic cultures of Thalassiosira pseudonana cultivated in phosphorus (P) replete and low P conditions w...

BACKGROUND Because apoptotic cell clearance appears to be defective in advanced compared with early atherosclerotic plaques, macrophage apoptosis may differentially affect plaque progression as a function of lesion stage. METHODS AND RESULTS We first evaluated the impact of targeted protection of macrophages against apoptosis at both early and advanced stages of atherosclerosis. Increased res...

Although it has been demonstrated that exercise training has an antiapoptotic effect on postmitotic myocytes, the mechanisms responsible for this effect are still largely unclear. Because the antiapoptotic effect of exercise training in postmitotic myocytes could be possibly mediated by the upregulation of apoptotic suppressors, this study examined the effect of endurance training on endogenous...
