The radiation-chemical behavior of Pd(II) in nitric acid solutions as a function of starting concentrations and absorbed radiation dose is studied under steady-state gamma-radiolysis conditions. Complexation of Pd(II) with nitrous acid formed as a radiolysis product of HNO3 occurs at all studied ...
This ROS production contributes to mitochondrial damage in a range of pathologies and is also important in redox signaling from the organelle to the rest of the cell. Consequently, knowledge of how mitochondria produce R 线粒体是ROS易反应的氧气种类的一个 (重要来源) 在多数哺乳细胞之内。 这ROS...
Apart from mitochondria, ROS are produced in the chloroplasts, the peroxisomes, and the apoplast, as well as in less commonly known locations, the nucleus and the endoplasmic reticulum(Overmyer et al., 2003; Ashtamker et al., 2007; Foyer and Noctor, 2009; Jaspers and Kangasjärvi, 2010;...
such as global warming, are gradually recognized; when the ambient temperature increases to the extent that it causes heat stress in plants, agricultural production will inevitably be affected. Therefore, several issues associated with heat stress in crops urgently need to be solved. Rice is one of...
2010). Under stress conditions, plants send signals to alter their metabolism for the synthesis/activation of defensive genes in affected plant parts (Gill et al. 2019). During stressful conditions, the ROS production rate dramatically increases in plants’ mitochondria, chloroplast, endoplasmic ...
With the intensification of the greenhouse effect, a series of natural phenomena, such as global warming, are gradually recognized; when the ambient temperature increases to the extent that it causes heat stress in plants, agricultural production will in
Liquid-to-solid phase transition of oskar ribonucleoprotein granules is essential for their function in Drosophila embryonic development. Cell https://doi.org/10.1016/j.cell.2022.02.022 (2022). This study shows that the regulation of osk RNP physical properties are important for asymmetric expression...
Although the amount of ATP synthesized by glycolysis per unit of glucose is small [19,20], the ATP synthesis rate is 10-100 times faster than that of complete oxidation in mitochondria; Thus, glycolysis can meet the rapid energy requirements of tumor cells [21]. DNA methylation can directly...
Inflamm-ageing refers to age-related changes in the inflammatory and immune systems which somehow drive the ageing process towards healthy or unhealthy ageing. Current evidences, support that, reversing the age-related pro-inflammatory status of inflamm-ageing, is able to modulate most hallmarks of ...
However, the primary source of ROS in broiler muscles is the leakage of electrons from the respiratory chain in mitochondria during the conversion of molecular oxygen to water (Mujahid et al.,2007). Also, it was hypothesized that elevated body temperature increased oxygen reaction possibly by ...
