Overwintering Periwinkle (Vinca minor L.) Exhibits Increased Photosystem I Activity.
The effects of natural, overwintering conditions on photosystem I and photosystem II activity were examined in isolated thylakoids of periwinkle (Vinca minor L.), an endemic, cold-tolerant, herbaceous evergreen. DCMU-Insensitive photosystem I activity (ascorbate/dichlorophenolindophenol --> methylviologen) exhibited a twofold increase in light-saturated rates upon exposure to low temperature an...
متن کاملMore than a decade has passed since the discovery in Caenorhabditis elegans that double-stranded RNA
| MicroRNAs (mi RNAs) are evolutionarily conserved small non-coding RNAs that have crucial roles in regulating gene expression. Increasing evidence supports a role for mi RNAs in many human diseases, including cancer and autoimmune disorders. The function of mi RNAs can be efficiently and specifically inhibited by chemically modified antisense oligonucleotides, supporting their potential as tar...
متن کاملExtraction and Liquid-Membrane Preconcentration of Vincamine from Periwinkle (Vinca Minor L.) Leaves. Process Modelling
An integrated process coupling solid-liquid extraction and liquid-membrane preconcentration of vincamine was studied. The effect of the ratios solid phase/extractant volume and extractant volume/liquid membrane volume on the mass transfer rate and efficiency of vincamine removal were estimated. It was found that the transfer rate and removal efficiency of the alkaloid were higher with smaller q...
