Medicinal use of the opium poppy (Papaver somniferum L) has ancient history, but the isolation of morphine was not described until the early nineteenth century. Morphine is the most important alkaloid of opium poppy in the last 50 years. In the morphine pathway has been reported to generate morphine in this species, CODM has a crucial role as the gene coding the enzyme respons...
Endogenous codeine and morphine were identified in rat brain by immunological determination following HPLC. To demonstrate occurrence of a biosynthetic pathway to morphine in mammals similar to that used by the poppy plant, (+)-salutaridine, (-)-thebaine, and (-)-codeine were administered to rats intravenously. These compounds, which are intermediates in the synthesis of morphine in Papaver som...
In this contribution, new data concerning the distribution of native vascular flora in Italy are presented. It includes records, confirmations, and exclusions to Italian administrative regions. New combinations genera Pilosella Roemeria proposed. Furthermore, name Papaver siculum is lectotypified. Nomenclatural updates, published elsewhere, corrigenda provided as Suppl. material 1.
The free-living flatworm, Macrostomum lignano has an impressive regenerative capacity. Following injury, it can regenerate almost an entirely new organism because of the presence of an abundant somatic stem cell population, the neoblasts. This set of unique properties makes many flatworms attractive organisms for studying the evolution of pathways involved in tissue self-renewal, cell-fate spec...
Papaver libanoticum is an endemic plant to Lebanese region (family Papaveraceae) that has not been investigated before. The present study aimed to explore the analgesic activity of dried ethanolic extract of Papaver libanoticum (PLE) using tail flick, hot plate, and acetic acid induced writhing models in mice. The involvement of opioid receptors in the analgesic mechanism was investigated using...

در این مطالعه 9 تاکسون از جنس papaver (sect. meconidium) مورد مطالعه و بررسی قرار گرفت. تاکسونp. persicum subsp. persicum var. glabrum به عنوان یک واریته جدید معرفی می گردد. تاکسونهایp. armeniacum subsp. armeniacum × subsp. pilgerianum و p. persicum × p. armeniacumبه عنوان دو رگه دو والدی معرفی می گردند. زیرگونهp. persicum subsp. microcarpum برای اولین بار از غرب ایران گزارش می شود. مورفول...
Sexual selection is considered a potent evolutionary force in all sexually reproducing organisms, but direct tests in terms of experimental evolution of sexual traits are still lacking for simultaneously hermaphroditic animals. Here, we tested how evolution under enforced monogamy affected a suite of reproductive traits (including testis area, sex allocation, genital morphology, sperm morpholog...
