Radula (plant)
''Radula'' is a genus of Marchantiophyta, liverwort, and is the only genus in family Radulaceae. It is a leafy liverwort. The appearance of the plants are as a scaly, green surface on the trunk of a tree, log or rock in a sheltered, moist out-door environment. The leaves are rounded, overlapping and consist of two unequal lobes. The smaller lobe is folded beneath the larger one. The oldest fossil species is ''Radula cretacea'' from the Cenomanian aged Burmese amber of Myanmar, belonging to the subgenus ''Odontoradula.'' Molecular evidence suggests that the genus arose during the Triassic, around 227.8 Ma, and the crown group began to diversify during the Early Jurassic, around 176.3 Ma. Species include: * ''Radula boninensis'' * ''Radula carringtonii'' J.B.Jack * ''Radula cavifolia'' * ''Radula complanata'' * ''Radula deflexilobula'' Promma, L.N.Zhang et R.L.Zhu * ''Radula demissa'' M.A.M.Renner, 2013 * ''Radula javanica'' * ''Radula jonesii'' Bouman, Dirkse & Yamada * ''Radula ...

Marchantiophyta
The Marchantiophyta () are a division of non-vascular land plants commonly referred to as hepatics or liverworts. Like mosses and hornworts, they have a gametophyte-dominant life cycle, in which cells of the plant carry only a single set of genetic information. It is estimated that there are about 9000 species of liverworts. Some of the more familiar species grow as a flattened leafless thallus, but most species are leafy with a form very much like a flattened moss. Leafy species can be distinguished from the apparently similar mosses on the basis of a number of features, including their single-celled rhizoids. Leafy liverworts also differ from most (but not all) mosses in that their leaves never have a costa (present in many mosses) and may bear marginal cilia (very rare in mosses). Other differences are not universal for all mosses and liverworts, but the occurrence of leaves arranged in three ranks, the presence of deep lobes or segmented leaves, or a lack of clearly diff ...

National Center For Biotechnology Information
The National Center for Biotechnology Information (NCBI) is part of the United States National Library of Medicine (NLM), a branch of the National Institutes of Health (NIH). It is approved and funded by the government of the United States. The NCBI is located in Bethesda, Maryland, and was founded in 1988 through legislation sponsored by US Congressman Claude Pepper. The NCBI houses a series of databases relevant to biotechnology and biomedicine and is an important resource for bioinformatics tools and services. Major databases include GenBank for DNA sequences and PubMed, a bibliographic database for biomedical literature. Other databases include the NCBI Epigenomics database. All these databases are available online through the Entrez search engine. NCBI was directed by David Lipman, one of the original authors of the BLAST sequence alignment program and a widely respected figure in bioinformatics. GenBank NCBI had responsibility for making available the GenBank DNA seque ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ScienceDaily
''Science Daily'' is an American website launched in 1995 that aggregates press releases and publishes lightly edited press releases (a practice called churnalism) about science, similar to Phys.org and EurekAlert!. The site was founded by married couple Dan and Michele Hogan in 1995; Dan Hogan formerly worked in the public affairs department of Jackson Laboratory writing press releases. The site makes money from selling advertisements. As of 2010, the site said that it had grown "from a two-person operation to a full-fledged news business with worldwide contributors". At the time, it was run out of the Hogans' home, had no reporters, and only reprinted press releases. In 2012, Quantcast Quantcast is an American technology company, founded in 2006, that specializes in AI-driven real-time advertising, audience insights and measurement. It has offices in the United States, Canada, Australia, Singapore, United Kingdom, Ireland, Fran ... ranked it at 614 with 2.6 million U.S. vi ...

Japan
Japan ( ja, 日本, or , and formally , ''Nihonkoku'') is an island country in East Asia. It is situated in the northwest Pacific Ocean, and is bordered on the west by the Sea of Japan, while extending from the Sea of Okhotsk in the north toward the East China Sea, Philippine Sea, and Taiwan in the south. Japan is a part of the Ring of Fire, and spans Japanese archipelago, an archipelago of List of islands of Japan, 6852 islands covering ; the five main islands are Hokkaido, Honshu (the "mainland"), Shikoku, Kyushu, and Okinawa Island, Okinawa. Tokyo is the Capital of Japan, nation's capital and largest city, followed by Yokohama, Osaka, Nagoya, Sapporo, Fukuoka, Kobe, and Kyoto. Japan is the List of countries and dependencies by population, eleventh most populous country in the world, as well as one of the List of countries and dependencies by population density, most densely populated and Urbanization by country, urbanized.

Perrottetinene
Perrottetinene is a naturally occurring cannabinoid compound found in liverworts from the genus ''Radula'' native to Japan, New Zealand and Costa Rica, namely '' Radula perrottetii'', ''Radula marginata'' and ''Radula laxiramea'', along with a number of similar compounds. Its chemical structure closely resembles that of THC, the main active component of marijuana but with a ''cis'' rather than ''trans'' conformation. The absolute configuration of perrottetinene was established in 2008 by an enantioselective total synthesis. In 2018, a study showed that perrottetinene is moderately psychoactive through activation of the cannabinoid receptor 1. The same study also reported reduced prostaglandin D2 Prostaglandin D2 (or PGD2) is a prostaglandin that binds to the receptor PTGDR (DP1), as well as CRTH2 (DP2). It is a major prostaglandin produced by mast cells – recruits Th2 cells, eosinophils, and basophils. In mammalian organs, large a ... and E2 brain concentrations in mice ...

Cannabinoid
Cannabinoids () are several structural classes of compounds found in the cannabis plant primarily and most animal organisms (although insects lack such receptors) or as synthetic compounds. The most notable cannabinoid is the phytocannabinoid tetrahydrocannabinol (THC) (delta-9-THC), the primary intoxicating compound in cannabis. Cannabidiol (CBD) is a major constituent of temperate Cannabis plants and a minor constituent in tropical varieties. At least 113 distinct phytocannabinoids have been isolated from cannabis, although only four (i.e., THCA, CBDA, CBCA and their common precursor CBGA) have been demonstrated to have a biogenetic origin. It was reported in 2020 that phytocannabinoids can be found in other plants such as rhododendron, licorice and liverwort, and earlier in Echinacea. Phytocannabinoids are multi-ring phenolic compounds structurally related to THC, but endocannabinoids are fatty acid derivatives. Nonclassical synthetic cannabinoids (cannabimimetics) include amin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
