Toxicity Persistence of Chlorpyrifos in Runoff from Experimental Soybean Plots to the Non-target Amphipod Hyalella curvispina: Effect of Crop Management
(Springer, 2015-07-04)
Toxicity persistence to the non-target amphipod Hyalella curvispina in runoff events following chlorpyrifos applications to soy experimental plots was compared in conventional and no-till management. Two application scenarios ...
Quantification and toxicity testing of pharmaceuticals in tropical marine sediments, All Saints Bay, Bahia, Brazil
(2013-03-19)
The presence and effects of pharmaceuticals in the environment have gained increased attention lately because of their widespread use and their potential to bioaccumulate and induce negative effects in aquatic and terrestrial ...
Concomitant Cisplatin Plus Radiotherapy and High-Dose-Rate Brachytherapy Versus Radiotherapy Alone for Stage IIIB Epidermoid Cervical Cancer: A Randomized Controlled Trial
(Amer Soc Clinical OncologyAlexandriaEUA, 2014)
Phytoplankton and protozooplankton on the southern Patagonian shelf (Argentina, 47°–55°S) in late summer: Potentially toxic species and community assemblage structure linked to environmental features
(Elsevier Science, 2018-10)
On the southern Patagonian shelf (Argentina, 47°–55°S) phyto- and protozooplankton are key structural and functional components of a complex trophic web that sustains commercially important species. During late summer 2004, ...
Exposure to toxic fescue during late gestation on beef cows: effects on cow performance and offspring performance from birth to weaning
(ECronicon Open Access, 2020-01-03)
To examine the effects of endophyte-infected tall fescue during late gestation on maternal and offspring performance, multiparous Angus cows (n = 40) were bred via AI and allocated into grazing treatments: toxic (E+) or ...
Analytical applications of microbial fuel cells. Part II: Toxicity, microbial activity and quantification, single analyte detection and other uses
(Elsevier, 2014-05-09)
Microbial fuel cells were rediscovered twenty years ago and now are a very active research area. The reasons behind this new activity are the relatively recent discovery of electrogenic or electroactive bacteria and the ...
Copper oxychloride fungicide and its effect on growth and oxidative stress of potato plants
(Elsevier B.V., 2014-06-01)
Excess copper in plants causes physiological alterations that lead to crop productivity losses. However, cupric fungicides have been utilized in the control of Alternaria solani and Phytophtora infestans fungi, which cause ...
Ammonium stress increases microautophagic activity while impairing macroautophagic flux in Arabidopsis roots
(Wiley, 2020-11-22)
Plant responses to NH4 + stress are complex, and multiple mechanisms underlying NH4 + sensitivity and tolerance in plants may be involved. Here, we demonstrate that macro‐ and microautophagic activities are oppositely ...
CutC is induced late during copper exposure and can modify intracellular copper content in Enterococcus faecalis
(Elsevier, 2011)
Copper is a micronutrient that is required for proper metabolic functioning of most prokaryotic and
eukaryotic organisms. To sustain an adequate supply of copper, a cell requires molecular mechanisms
that control the ...
