Nitric oxide (NO) is a highly reactive signaling molecule and plays a variety of physiological roles in plants. The research on the application of NO to postharvest preservation of flowers and fruits shows great promise in recent years. However, the physiological mechanism of exogenous NO to affect cut flowers is not very clear, and NO donor treatment protected plants from damage by increasing ...

A number of studies have previously provided evidence on the Anti-inflammatory properties of plant-derived compounds that can prevent lung injury. In this study, we attempted to analyze the therapeutic effects of PM 014 on inflammation and pulmonary fibrosis in COVID-19 as well as describing the treatment of one of the most challenging problems related to the coronavirus-19 (COVID-19). We belie...

kinematic synthesis of a trailing six-member mechanism has been carried out to achieve five precision points of an automotive steering mechanism. the inner wheel can be rotated up to forty five degrees with fair accuracy. results show that the divergent end behavior of ackermann steering mechanism has been overcome by the present mechanism. the work is similar to earlier work by the present aut...

reactive oxygen species (ros)plays an important role in sperm motility. the physiological generation at low concentration induces beneficial effects on sperm functions and plays a significant role in sperm metabolism. meanwhile, the excessive generation of reactive oxygen species can overwhelm protective mechanism and triggers changes in lipid and protein layers of sperm plasma membrane, which ...
