Antigenotoxic Capacity of Papaver Rhoeas L
Application of exogenic bioactive natural plant compounds with protective, anti-mutagenic and anti-genotoxic effects against various chemical and physical agents is one of the modern approaches for reduction of the mutagenic burden of cells. Objective: The present study aims to provide data on the cytoxic and genotoxic effects of Papaver rhoeas L. water leaf extract and its anti-cytotoxic and a...
متن کاملThe actin cytoskeleton is a target of the self-incompatibility response in Papaver rhoeas.
The integration of signals received by a cell, and their transduction to targets, is essential for all cellular responses. The cytoskeleton has been identified as a major target of signalling cascades in both animal and plant cells. Self-incompatibility (SI) in Papaver rhoeas involves an allele-specific recognition between stigmatic S-proteins and pollen, resulting in the inhibition of incompat...
متن کاملInvolvement of extracellular calcium influx in the self-incompatibility response of Papaver rhoeas.
We have previously demonstrated that increases in cytosolic free Ca2+ are triggered by the self-incompatibility (SI) response in incompatible Papaver rhoeas (the field poppy) pollen. However, one key question that has not been answered is whether extracellular Ca2+ may be involved. To address this question, we have used an ion-selective vibrating probe to measure changes in extracellular Ca2+ f...
متن کاملCytotoxic Activity of Alkaloids from Papaver rhoeas growing in Lebanon
This paper represents the phytochemical properties of Lebanese Papaver rhoeas, from which five protopine alkaloids are isolated, namely; stylopine (1), canadine (2), sinactine (3), berberine (4), and epiberberine (5). This is the first report for the isolation of epiberberine (5) from the genus Papaver and canadine (2) from Papaver rhoeas, suggesting a new chemotype of Papaver rhoeas growing in...
متن کاملIntoxication due to Papaver rhoeas (Corn Poppy): Five Case Reports
Introduction. In this paper, we aimed to present five Papaver rhoeas intoxication cases, which is very rare in the literature. Case 1. A 35-year-old female patient was admitted to our emergency room with the complaints of nausea, restlessness, and dyspnea developing 3 hours after eating Papaver rhoeas. On physical examination, her general condition was moderate; she was conscious and the vital ...
