MicroRNAs (miRNAs) are approximately 20-22 nucleotide non-coding RNAs, which play an important role in posttranscriptional degradation of target mRNA or inhibition of protein synthesis through binding the specific sites of target mRNA. miRNAs have been extensively studied in various plant species, however, there is no miRNA identified in Cannabis sativa, a crop which has long been used for hemp...

introduction: some studies have demonstrated the potential of herbal drugs for the treatment of various diseases associated with impaired vascular nitric oxide (no). for diagnosis of the mechanism of these herbal plants, it seems necessary to evaluate the herbal extracts on the endothelium cell. the aim of the study was to investigate the effect of extract of trigonella foenum-graecum (t.foenum...

Illegal cannabis (Cannabis sativa L.) cultivation is still a social problem worldwide. Fifty inquiries on cannabis that Research Center for Medicinal Plant Resources (Tsukuba Division) received between January 1, 2000 and March 31, 2009 were itemized in to 8 categories; 1: seed identification, 2: plant identification, 3: indoor cultivation, 4: outdoor cultivation, 5: germination and growth char...

Cannabis sativa L. is an important economic plant for the production of food, fiber, oils, and intoxicants. However, lack of sufficient simple sequence repeat (SSR) markers has limited the development of cannabis genetic research. Here, large-scale development of expressed sequence tag simple sequence repeat (EST-SSR) markers was performed to obtain more informative genetic markers, and to asse...

Current debate on Cannabis sativa in South Africa has centred on its positive and negative effects on health, as well as its decriminalisation. The contribution of cannabis (dagga) to the livelihoods of people who inhabit some of the poorest parts of the country has thus far been largely ignored. Using a case study of a village in Pondoland, this article argues that while cannabis makes a signi...

Objective(s): Metastasis is the main cause of death in patients with melanoma. Cannabis-based medicines are effective adjunctive drugs in cancer patients. Tau and Stathmin proteins are the key proteins in cancer metastasis. Here we have investigated the effect of a standardized Cannabis sativa extract on cell migration and Tau and Stathmin gene expression in the melanoma cell line. Materials an...

BACKGROUND Cannabis is a widely used illicit drug with various threats of personality syndrome, and Nigella sativa has been widely implicated as having therapeutic efficacy in many neurological diseases. The present study investigates the ameliorative efficacy of Nigella sativa oil (NSO) on cannabis-induced moto-cognitive defects. METHODS Scopolamine (1 mg/kg i.p.) was given to induce dementi...

The Δ(9-)Tetrahydrocannabinol (THCA) is the primary psychoactive compound of Cannabis Sativa. It is produced by Δ(1-) Tetrahydrocannabinolic acid synthase (THCA) which catalyzes the oxidative cyclization of cannabigerolic acid (CBGA) the precursor of the THCA. In this study, we were interested by the three dimensional structure of THCA synthase protein. Generation of models were done by MODELLE...
