A model is presented of the regulation of ethylene biosynthesis in relation to submergence and flooding resistance. It is based on time-course measurements of ethylene production, ethylene accumulation, and concentrations of free and conjugated 1-aminocyclo-propane-1-carboxylic acid (ACC) in submerged and drained flooding-resistant Rumex palustris Sm. and flooding-sensitive Rumex acetosella L. ...

BACKGROUND: Breast cancer is a major cause of morbidity, mortality, and medical expenditures among women in Canada. Essiac (Resperin Canada Limited, Waterloo, Ontario, Canada), a blend of at least four herbs (burdock root [Arctium lappa], Indian rhubarb [Rheum palmatum], sheep sorrel [Rumex acetosella], and the inner bark of slippery elm [Ulmus fulva or U. rubra]), has become one of the more po...

Floristics of Vittadinia triloba communities in Central Otago and the upper Waitaki valley and Rumex acetosella communities in the upper Waitaki, are compared with each other and with similar communities elsewhere in the South Island. Many species are common to all semi-arid areas, but each area has as its own special features, either the presence of a particular species or the greater abundanc...

The Rumex L. (dock) species for many centuries have been used in medical treatment, through their adstringent, spasmolitic or cholagogic action. In the present study, the in vitro screening of cytotoxic activities of ethanol extract from roots, leaves and fruits of six Rumex species: R. acetosa L., R. acetosella L., R. confertus Willd., R. crispus L., R. hydrolapathum Huds. and R. obtusifolius ...

Nanopartiküller teknolojinin birçok alanında sıklıkla kullanılmaktadırlar. Diğer metal nanopartiküller içerisinde en çok kullanılanlar gümüş nanopartiküllerdir. Kendilerine has özellikleri ortaya çıktıkça nanobiyoteknoloji alanındaki kullanımları da hızla artış göstermektedir. Gümüş nanopartiküllerin sentezinde farklı yöntemler kullanılmaktadır. Yeşil sentez (biyosentez) yöntemi nanopartikül el...

Turkey has highly rich floras of medicinal and aromatic plants because of having various climate conditions in different regions. One of these regions is Middle Black Sea Region, especially Ordu Province. Extracts of 10 edible plants (Arum maculatum L., Hypericum orientale L., Ornithogalum sigmoideum Freyn et Sint., Silene vulgaris Garcke var. macrocarpa, Plantago lanceolata L., Achillea millef...
