The zooplankton community structure in Eğirdir Lake (Isparta-Turkey) was studied monthly throughout an annual cycle (January 2010-December 2010). The zooplankton community was represented by three main groups: Rotifera, Cladocera and Copepoda, respectively comprised 89.62%, 7.78% and 2.60% of the total zooplankton abundance. Eğirdir Lake was dominated by the rotifera Polyarthra dolichoptera in ...
BACKGROUND: The active oxygen species, despite the damaging effects they have useful roles in the body are living things. OBJECTIVES: This research was done to determine whether Reactive Oxygen Species (ROS) could mediate Cyanide and Methylviologen signal in seed dormancy alleviation and sunflower seed germination, more widely, to assess their putative ro...
Owing to their fast diffusion, reactive oxygen species (ROS) are important tissue signalling components. High levels of ROS are generally considered as deleterious to cells. In vivo experiments in the Drosophila hematopoietic organ now challenge this view by showing that high ROS levels are intrinsically required to prime myeloid-like progenitors to differentiate.
Bactericidal antibiotics kill by modulating their respective targets. This traditional view has been challenged by studies that propose an alternative, unified mechanism of killing, whereby toxic reactive oxygen species (ROS) are produced in the presence of antibiotics. We found no correlation between an individual cell's probability of survival in the presence of antibiotic and its level of RO...
As discussed in Chapter 1, around three billion years ago, life on Earth consisted of anaerobic microbes subsisting on the energy provided by cycles of electron transfer between prevalent populations of electron donors and acceptors. Potential donors were molecular hydrogen (H2), hydrogen sulfide (H2S) and methane (CH4), whose electrons were transferred to acceptors such as carbon dioxide (CO2)...
D ioxygen is a highly important, yet toxic, molecule that reacts in vivo to produce reactive oxygen species such as superoxide, peroxides, hydroxyl radicals, and other related species. Those species play important roles in healthy organisms, and they are implicated in aging and a wide range of disease processes as well. The contents of this Special Feature on Reactive Oxygen Species in Chemistr...
