Castela Emoryi
''Castela emoryi'', with the common names crucifixion thorn, Emory's crucifixion-thorn, and es, chaparro amargosa, is a shrub species in the genus ''Castela'' of the family (biology), family Simaroubaceae. Distribution The plant is native to the Mojave Desert and Sonoran Deserts of North America. It is found in southern California, Arizona, and Sonora state (México). The species is dioecious and occurs in the moistest areas in the hottest, driest deserts within its range; it is considered poor in germination. Description ''Castela emoryi'' is often less than , and occasionally to grows or more. Crucifixion thorn is mostly leafless, its sharp branches are green and perform photosynthesis. Seeds are contained in clusters of fruit in groups of 5. The fruit is tan, green, red or brown in color, turning black with age. and may persist on the tree for several years. It is ranked on the California Native Plant Society Inventory of Rare and Endangered Plants, as an endange ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lignan
The lignans are a large group of low molecular weight polyphenols found in plants, particularly seeds, whole grains, and vegetables. The name derives from the Latin word for "wood". Lignans are precursors to phytoestrogens. They may play a role as antifeedants in the defense of seeds and plants against herbivores. Biosynthesis and metabolism Lignans and lignin differ in their molecular weight, the former being small and soluble in water, the latter being high polymers that are undigestable. Both are polyphenolic substances derived by oxidative coupling of monolignols. Thus, most lignans feature a C18 cores, resulting from the dimerization of C9 precursors. The coupling of the lignols occurs at C8. Eight classes of lignans are: "furofuran, furan, dibenzylbutane, dibenzylbutyrolactone, aryltetralin, arylnaphthalene, dibenzocyclooctadiene, and dibenzylbutyrolactol." Many lignans are metabolized by mammalian gut microflora, producing so-called enterolignans. Food sources Flax s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prunus Mume
''Prunus mume'' is an East Asian and Southeast Asian tree species classified in the ''Armeniaca'' section of the genus ''Prunus'' subgenus ''Prunus''. Its common names include Chinese plum, Japanese plum, and Japanese apricot. The flower, long a beloved subject in the traditional painting and poetry of East Asia and Vietnam, is usually called plum blossom. This distinct tree species is related to both the plum and apricot trees. Although generally referred to as a plum in English, it is more closely related to the apricot. In East Asian cuisine (Chinese, Japanese and Korean) and Vietnamese cuisine, the fruit of the tree is used in juices, as a flavouring for alcohol, as a pickle and in sauces. It is also used in traditional medicine. The tree's flowering in late winter and early spring is highly regarded as a seasonal symbol. ''Prunus mume'' should not be confused with ''Prunus salicina'', a related species also grown in China, Japan, Korea and Vietnam. Another tree, ''Prunus ...

Helicobacter Pylori
''Helicobacter pylori'', previously known as ''Campylobacter pylori'', is a gram-negative, microaerophilic, spiral (helical) bacterium usually found in the stomach. Its helical shape (from which the genus name, helicobacter, derives) is thought to have evolved in order to penetrate the mucoid lining of the stomach and thereby establish infection. The bacterium was first identified in 1982 by the Australian doctors Barry Marshall and Robin Warren. ''H. pylori'' has been associated with cancer of the mucosa-associated lymphoid tissue in the stomach, esophagus, colon, rectum, or tissues around the eye (termed extranodal marginal zone B-cell lymphoma of the cited organ), and of lymphoid tissue in the stomach (termed diffuse large B-cell lymphoma). ''H. pylori'' infection usually has no symptoms but sometimes causes gastritis (stomach inflammation) or ulcers of the stomach or first part of the small intestine. The infection is also associated with the development of cer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motility
Motility is the ability of an organism to move independently, using metabolic energy. Definitions Motility, the ability of an organism to move independently, using metabolic energy, can be contrasted with sessility, the state of organisms that do not possess a means of self-locomotion and are normally immobile. Motility differs from mobility, the ability of an object to be moved. The term vagility encompasses both motility and mobility; sessile organisms including plants and fungi often have vagile parts such as fruits, seeds, or spores which may be dispersed by other agents such as wind, water, or other organisms. Motility is genetically determined, but may be affected by environmental factors such as toxins. The nervous system and musculoskeletal system provide the majority of mammalian motility. In addition to animal locomotion, most animals are motile, though some are vagile, described as having passive locomotion. Many bacteria and other microorganisms, and multicellu ...

In Vitro
''In vitro'' (meaning in glass, or ''in the glass'') studies are performed with microorganisms, cells, or biological molecules outside their normal biological context. Colloquially called "test-tube experiments", these studies in biology and its subdisciplines are traditionally done in labware such as test tubes, flasks, Petri dishes, and microtiter plates. Studies conducted using components of an organism that have been isolated from their usual biological surroundings permit a more detailed or more convenient analysis than can be done with whole organisms; however, results obtained from ''in vitro'' experiments may not fully or accurately predict the effects on a whole organism. In contrast to ''in vitro'' experiments, ''in vivo'' studies are those conducted in living organisms, including humans, and whole plants. Definition ''In vitro'' ( la, in glass; often not italicized in English usage) studies are conducted using components of an organism that have been isolated fro ...
