Cordyceps Militaris
''Cordyceps militaris'' is a species of fungus in the family Cordycipitaceae, and the type species of the genus ''Cordyceps''. It was originally described by Carl Linnaeus in 1753 as ''Clavaria militaris''. Description Macroscopic characteristics The fungus forms 1–8 cm high, club-shaped and orange/red fruiting bodies, which grow out of dead underground pupae. The club is covered with the stroma, into which the actual fruit bodies, the perithecia, are inserted. The surface appears roughly punctured. The inner fungal tissue is whitish to pale orange. Microscopic features The spores are smooth, hyaline, long-filiform, and often septate. They decompose to maturity in 3–7 μm × 1–1.2 μm subpores. The asci are long and cylindrical. Sometimes an anamorphic state, which is ''Isaria'', is found. Masses of white mycelia form around the parasitised insect; however, these may not be of the same species. Ecology and dispersal ''Cordyceps militaris'' is a entomopathogenic f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungi
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mycelia
Mycelium (plural mycelia) is a root-like structure of a fungus consisting of a mass of branching, thread-like hyphae. Fungal colonies composed of mycelium are found in and on soil and many other substrates. A typical single spore germinates into a monokaryotic mycelium, which cannot reproduce sexually; when two compatible monokaryotic mycelia join and form a dikaryotic mycelium, that mycelium may form fruiting bodies such as mushrooms. A mycelium may be minute, forming a colony that is too small to see, or may grow to span thousands of acres as in ''Armillaria''. Through the mycelium, a fungus absorbs nutrients from its environment. It does this in a two-stage process. First, the hyphae secrete enzymes onto or into the food source, which break down biological polymers into smaller units such as monomers. These monomers are then absorbed into the mycelium by facilitated diffusion and active transport. Mycelia are vital in terrestrial and aquatic ecosystems for their role in t ...

Mitochondrion
A mitochondrion (; ) is an organelle found in the cells of most Eukaryotes, such as animals, plants and fungi. Mitochondria have a double membrane structure and use aerobic respiration to generate adenosine triphosphate (ATP), which is used throughout the cell as a source of chemical energy. They were discovered by Albert von Kölliker in 1857 in the voluntary muscles of insects. The term ''mitochondrion'' was coined by Carl Benda in 1898. The mitochondrion is popularly nicknamed the "powerhouse of the cell", a phrase coined by Philip Siekevitz in a 1957 article of the same name. Some cells in some multicellular organisms lack mitochondria (for example, mature mammalian red blood cells). A large number of unicellular organisms, such as microsporidia, parabasalids and diplomonads, have reduced or transformed their mitochondria into other structures. One eukaryote, ''Monocercomonoides'', is known to have completely lost its mitochondria, and one multicellular organism, '' ...

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 ...

Apoptosis
Apoptosis (from grc, ἀπόπτωσις, apóptōsis, 'falling off') is a form of programmed cell death that occurs in multicellular organisms. Biochemical events lead to characteristic cell changes (morphology) and death. These changes include blebbing, cell shrinkage, nuclear fragmentation, chromatin condensation, DNA fragmentation, and mRNA decay. The average adult human loses between 50 and 70 billion cells each day due to apoptosis. For an average human child between eight and fourteen years old, approximately twenty to thirty billion cells die per day. In contrast to necrosis, which is a form of traumatic cell death that results from acute cellular injury, apoptosis is a highly regulated and controlled process that confers advantages during an organism's life cycle. For example, the separation of fingers and toes in a developing human embryo occurs because cells between the digits undergo apoptosis. Unlike necrosis, apoptosis produces cell fragments called apoptotic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cordycepin
Cordycepin, or 3'-deoxyadenosine, is a derivative of the nucleoside adenosine, differing from the latter by the replacement of the hydroxy group in the 3' position with a hydrogen. It was initially extracted from the fungus ''Cordyceps militaris'', but can now be produced synthetically. It is also found in other ''Cordyceps'' species as well as ''Ophiocordyceps sinensis''. Because cordycepin is similar to adenosine, some enzymes cannot discriminate between the two. It can therefore participate in certain biochemical reactions (for example, 3-dA can trigger the premature termination of mRNA synthesis). By acting as an adenosine analog, cordycepin was found to be the most potent molecular circadian clock resetter out of several screened compounds. Cordycepin has displayed cytotoxicity against some leukemic cell lines ''in vitro''. Cordycepin has been found to produce rapid, robust imipramine-like antidepressant effects in animal models of depression, and these effects, similarly ...

Ophiocordyceps Sinensis
''Ophiocordyceps sinensis'' (formerly known as ''Cordyceps sinensis''), known colloquially as caterpillar fungus, is an entomopathogenic fungus (a fungus that grows on insects) in the family Ophiocordycipitaceae. It is mainly found in the meadows above on the Tibetan Plateau in Southwest China and the Himalayan regions of Bhutan and Nepal. It parasitizes larvae of ghost moths and produces a fruiting body which used to be valued as a herbal remedy and in traditional Chinese medicine. Caterpillar fungus contains the compound cordycepin, an adenosine derivative. However, the fruiting bodies harvested in nature usually contain high amounts of arsenic and other heavy metals so they are potentially toxic and sales have been strictly regulated by the CFDA (China Food and Drug Administration) since 2016. ''O. sinensis'' parasitizes the larvae of moths within the family Hepialidae, specifically genera found on the Tibetan Plateau and in the Himalayas, between elevations of . The fung ...

Hot Pot
Hot pot or hotpot (), also known as soup-food or steamboat, is a cooking method that originated in China. A heat source on the dining table keeps a pot of soup stock simmering, and a variety of Chinese foodstuffs and ingredients are served beside the pot for the diners to put into the hot stock. Description Hot pot is a flavorful broth traditionally served inside a large metal pot. The broth is brought to a boil and left simmering for the duration of the meal. Raw ingredients, such as meat and vegetables, are placed into the simmering broth and thus cooked. The cooked pieces are dipped into dipping sauces for additional flavor. Hot pot is considered a main course and is usually served without rice or noodles on the side. Hot pots can be prepared and eaten at home or in a restaurant. Typical hot pot ingredients include thinly sliced meat, leaf vegetables, mushrooms, vermicelli, sliced potatoes, bean products, egg dumplings, tofu, and seafood. Raw ingredients are pre-sliced ...

Chicken Soup
Chicken soup is a soup made from Chicken (food), chicken, simmered in water, usually with various other ingredients. The classic chicken soup consists of a clear broth, chicken broth, often with pieces of chicken or vegetables; common additions are pasta, noodles, dumplings, or grains such as rice and barley. Chicken soup has acquired the reputation of a Home remedy, folk remedy for common cold, colds and influenza, and in many countries is considered a comfort food. History Humans were already boiling food by the time that Domestic fowl, chicken was domesticated in the neolithic, neolithic period, so it is likely that chickens were being boiled for soup. Modern American chicken soup, which typically includes root vegetables such as carrot, onion, leeks and celery, was a staple across Northern Europe and was brought to the United States by immigrants. Preparation Variations on the flavor are gained by adding root vegetables such as parsnip, potato, sweet potato and celery r ...

Pupae
A pupa ( la, pupa, "doll"; plural: ''pupae'') is the life stage of some insects undergoing transformation between immature and mature stages. Insects that go through a pupal stage are holometabolous: they go through four distinct stages in their life cycle, the stages thereof being egg, larva, pupa, and imago. The processes of entering and completing the pupal stage are controlled by the insect's hormones, especially juvenile hormone, prothoracicotropic hormone, and ecdysone. The act of becoming a pupa is called pupation, and the act of emerging from the pupal case is called eclosion or emergence. The pupae of different groups of insects have different names such as ''chrysalis'' for the pupae of butterflies and ''tumbler'' for those of the mosquito family. Pupae may further be enclosed in other structures such as cocoons, nests, or shells. Position in life cycle The pupal stage follows the larval stage and precedes adulthood (''imago'') in insects with complete metamorphosi ...
