Medical Subject Headings
Medical Subject Headings (MeSH) is a comprehensive controlled vocabulary for the purpose of indexing journal articles and books in the life sciences. It serves as a thesaurus that facilitates searching. Created and updated by the United States National Library of Medicine (NLM), it is used by the MEDLINE/ PubMed article database and by NLM's catalog of book holdings. MeSH is also used by ClinicalTrials.gov registry to classify which diseases are studied by trials registered in ClinicalTrials. MeSH was introduced in the 1960s, with the NLM's own index catalogue and the subject headings of the Quarterly Cumulative Index Medicus (1940 edition) as precursors. The yearly printed version of MeSH was discontinued in 2007; MeSH is now available only online. It can be browsed and downloaded free of charge through PubMed. Originally in English, MeSH has been translated into numerous other languages and allows retrieval of documents from different origins. Structure MeSH vocabulary is ...

Caulerpa
''Caulerpa'' is a genus of seaweeds in the family Caulerpaceae (among the green algae). They are unusual because they consist of only one cell with many nuclei, making them among the biggest single cells in the world. A species in the Mediterranean can have a stolon more than long, with up to 200 fronds. This species can be invasive from time to time. Referring to the crawling habit of its thallus, the name means 'stem (that) creeps', from the Ancient Greek ' (, ‘stalk’) and ' (, ‘to creep’). Taxonomy and nomenclature First described by Jean Vincent Lamouroux in 1809, ''Caulerpa'' is the only genus under the family Caulerpaceae, from the order Bryopsidales, class Ulvophyceae, and phylum Chlorophyta. Through the use of ''tuf''A gene sequencing, it was revealed that ''Pseudochlorodesmis'' F. Børgesen was a sister clade of ''Caulerpa''. Cremen et al. proposed a new classification scheme in Bryopsidales, wherein Caulerpaceae and Halimedaceae were described as sister f ...

Porphyra
''Porphyra'' is a genus of coldwater seaweeds that grow in cold, shallow seawater. More specifically, it belongs to red algae phylum of laver species (from which comes laverbread), comprising approximately 70 species.Brodie, J.A. and Irvine, L.M. 2003. ''Seaweeds of the British Isles.'' Volume 1 Part 3b. The Natural History Museum, London. It grows in the intertidal zone, typically between the upper intertidal zone and the splash zone in cold waters of temperate oceans. In East Asia, it is used to produce the sea vegetable products '' nori'' (in Japan) and '' gim'' (in Korea). There are considered to be 60 to 70 species of ''Porphyra'' worldwide Kain, J.M. 1991.

Laurencia
''Laurencia'' is a genus of red algae that grow in temperate and tropical shore areas, in littoral to sublittoral habitats, at depths up to . Description ''Laurencia'' species have a thallus that is erect or decumbent with distichous, whorled or radial branch arrangement. Taxonomy and Nomenclature The genus name of ''Laurencia'' is in honour of Louis Jean de La Laurencie (1768-1829), who was a French Naval officer, Director of the University of Limoges and also a friend of the author, Jean Vincent Félix Lamouroux. The genus was circumscribed by Jean Vincent Félix Lamouroux in Ann. Mus. Natl. Hist. Nat. vol.20 on page 130 in 1813. It included an initial description of eight species which then subsequently underwent taxonomic revisions. The genus belongs to order Ceramiales reported to have 137 species, with a rich body of knowledge spanning for more than 50 years of research. ''Laurencia'' belongs to the family Rhodomelaceae which is considered to be one of the largest m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Algae, Red
Red algae, or Rhodophyta (, ; ), are one of the oldest groups of eukaryotic algae. The Rhodophyta also comprises one of the largest phyla of algae, containing over 7,000 currently recognized species with taxonomic revisions ongoing. The majority of species (6,793) are found in the Florideophyceae (class), and mostly consist of multicellular, marine algae, including many notable seaweeds. Red algae are abundant in marine habitats but relatively rare in freshwaters. Approximately 5% of red algae species occur in freshwater environments, with greater concentrations found in warmer areas. Except for two coastal cave dwelling species in the asexual class Cyanidiophyceae, there are no terrestrial species, which may be due to an evolutionary bottleneck in which the last common ancestor lost about 25% of its core genes and much of its evolutionary plasticity. The red algae form a distinct group characterized by having eukaryotic cells without flagella and centrioles, chloroplasts that lac ...

Volvox
''Volvox'' is a polyphyletic genus of chlorophyte green algae in the family Volvocaceae. It forms spherical colonies of up to 50,000 cells. They live in a variety of freshwater habitats, and were first reported by Antonie van Leeuwenhoek in 1700. ''Volvox'' diverged from unicellular ancestors approximately . Description ''Volvox'' is a polyphyletic genus in the volvocine green algae clade. Each mature ''Volvox'' colony is composed of up to thousands of cells from two differentiated cell types: numerous flagellate somatic cells and a smaller number of germ cells lacking in soma that are embedded in the surface of a hollow sphere or coenobium containing an extracellular matrix made of glycoproteins. Adult somatic cells comprise a single layer with the flagella facing outward. The cells swim in a coordinated fashion, with distinct anterior and posterior poles. The cells have anterior eyespots that enable the colony to swim toward light. The cells of colonies in the more ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ulva
Ulva (; gd, Ulbha) is a small island in the Inner Hebrides of Scotland, off the west coast of Mull. It is separated from Mull by a narrow strait, and connected to the neighbouring island of Gometra by a bridge. Much of the island is formed from Cenozoic basalt rocks, which are formed into columns in places. Ulva has been populated since the Mesolithic and there are various Neolithic remains on the island. The Norse occupation of the island in the Early Middle Ages has left few tangible artefacts but did bequeath the island its name, which is probably from ''Ulvoy'', meaning "wolf island". Celtic culture was a major influence during both Pictish and Dalriadan times as well as the post-Norse period when the islands became part of modern Scotland. This long period, when Gaelic became the dominant language, was ended by the 19th-century Clearances. At its height, Ulva had a population of over 800, but by May 2019, this had declined to 5; some increase in the number of resident ...

Scenedesmus
''Scenedesmus'' is a genus of green algae, in the class Chlorophyceae. They are colonial and non-motile. Taxonomy Currently, there are 74 taxonomically accepted species of ''Scenedesmus''. Additionally, several subgenera have been identified, but vary according to the source. Hegewald denotes ''Acutodesmus'', ''Desmodesmus'', and ''Scenedesmus'' as the three major categories. ''Acutodesmus'' is characterized as having acute cell poles, while ''Desmodesmus'' and ''Scenedesmus'' have obtuse/truncated cell poles (differentiated by the presence or absence of spines respectively). Fossil records date ''Scenedesmus'' from 70 to 100 million years ago with ''Desmodesmus'' suspected to be the youngest of these three groups. Basic biology ''Scenedesmus'' is one of the most common freshwater algae genera; however, the extremely diverse morphologies found within species make identification difficult.Lürling, Miquel. The Smell of Water: Grazer-Induced Colony Formation in Scenedesmus. Thes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prototheca
''Prototheca'' is a genus of algae in the family Chlorellaceae. All the species within this genus, even though classified as green algae, have forfeited their photosynthetic ability and have switched to parasitism. Some species can cause the disease protothecosis, otherwise known as Algaemia. Symptoms include: Cutaneous lesions, Olecranon bursitis. Etymology From the Greek ''proto''- (first) + ''thēkē'' (sheath), ''Prototheca'' is a genus of variably shaped spherical cells of achloric algae in the family Chlorellaceae. Wilhelm Krüger, a German expert in plant physiology and sugar production, reported ''Prototheca'' microorganisms in 1894, shortly after spending 7 years in Java studying sugarcane. He isolated ''Prototheca'' species from the sap of 3 tree species. Krüger named these organisms as ''P. moriformis'' and ''P. zopfii'', the second name as a tribute to Friedrich Wilhelm Zopf Friedrich (or Friederich) Wilhelm Zopf (12 December 1846 – 24 June 1909) was a well- ...
