Achyrocline Satureioides
''Achyrocline satureioides'', commonly known as macela or marcela, is a species of plant in the family Asteraceae. It is native to South America, from Argentina to Colombia to Guyana. A semi-annual herbaceous plant reaching about a meter tall, it has simple, narrow green leaves with serrated edges. It produces yellow flowers in racemes around Easter. Uses It is used as the medicinal plant symbol of Rio Grande do Sul state in Brazil. This plant is widely used in various countries which share the Guarani cultural heritage such as Paraguay, Uruguay, and northern Argentina, where it is used to treat stomach, digestive, and gastrointestinal disorders during pregnancy. The species' extract, which contains isorhamnetin, luteolin, and quercetin, is used to fight herpes. A. satureioides extract might have antiviral effects against the Western equine encephalitis virus. The extract could also have immunomodulatory properties. In general, it can help with management of viral respirato ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean-Baptiste Lamarck
Jean-Baptiste Pierre Antoine de Monet, chevalier de Lamarck (1 August 1744 – 18 December 1829), often known simply as Lamarck (; ), was a French naturalist, biologist, academic, and soldier. He was an early proponent of the idea that biological evolution occurred and proceeded in accordance with Naturalism (philosophy), natural laws. Lamarck fought in the Seven Years' War against Prussia, and was awarded a commission for bravery on the battlefield. Posted to Monaco, Lamarck became interested in natural history and resolved to study medicine.#Packard, Packard (1901), p. 15. He retired from the army after being injured in 1766, and returned to his medical studies. Lamarck developed a particular interest in botany, and later, after he published the three-volume work ''Flore françoise'' (1778), he gained membership of the French Academy of Sciences in 1779. Lamarck became involved in the Jardin des Plantes and was appointed to the Chair of Botany in 1788. When the French Nationa ...

Herpes Simplex
Herpes simplex, often known simply as herpes, is a viral disease, viral infection caused by the herpes simplex virus. Herpes infections are categorized by the area of the body that is infected. The two major types of herpes are Cold sore, oral herpes and genital herpes, though Herpes simplex#Types of herpes, other forms also exist. Oral herpes involves the face or mouth. It may result in small blisters in groups, often called cold sores or fever blisters, or may just cause a sore throat. Genital herpes involves the genitalia. It may have minimal symptoms or form blisters that break open and result in small ulcers. These typically heal over two to four weeks. Tingling or shooting pains may occur before the blisters appear. Herpes cycles between periods of active disease followed by periods without symptoms. The first episode is often more severe and may be associated with fever, muscle pains, swollen lymph nodes and headaches. Over time, episodes of active disease decrease in ...

Flora Of Rio Grande Do Sul
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is ''funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was ...

Flora Of Uruguay
The flora of Uruguay consists of 2,500 species distributed among 150 native and foreign biological families. Approximately 80% of Uruguay is prairie, with grasses predominating. Uruguay is primarily a grass-growing land, with vegetation that is essentially a continuation of the Argentine Pampas. Forest areas are relatively small. Trees grow in bunches. Forested areas are much smaller than in the pampas, but contain a mix of hardwoods and softwoods, while eucalyptus were imported from Australia. "Ceibo", or '' Erythrina cristagalli'', is the national flower. Herbs Uruguay contains many herbs, ferns, and flowers. Riverine forests Natural forests in Uruguay mainly grow near rivers in the countryside. The native forests are composed of more than 500 native species, including palms. The most abundant are "sauce criollo" ('' Salix humboldtiana''), "sarandí colorado" (''Cephalanthus glabratus''), "sarandí blanco" ('' Phyllanthus sellowianus'') and "mataojos" ('' Pouteria salicif ...

Flora Of Brazil
The wildlife of Brazil comprises all naturally occurring animals, plants, and fungus, fungi in the South American country. Home to 60% of the Amazon Rainforest, which accounts for approximately one-tenth of all species in the world, Brazil is considered to have the greatest biodiversity of any country on the planet. It has the most known species of plants (60,000), freshwater fish (3,000), Amphibian, amphibians (1,188), Snake, snakes (430), Insect, insects (90,000) and mammals (775). It also ranks third on the list of countries with the most bird species (1,971) and the third with the most reptile species (848). The number of fungal species is unknown (+3,300 species).Da Silva, M. and D.W. Minter. 1995. ''Fungi from Brazil recorded by Batista and Co-workers''. Mycological Papers 169. CABI, Wallingford, UK. 585 pp. Approximately two-thirds of all species worldwide are found in tropical areas, often coinciding with developing cou ...

Flora Of Argentina
The environment of Argentina is highly biodiverse. Biodiversity Flora Subtropical plants dominate the Gran Chaco in the north, with the '' Dalbergia'' genus of trees well represented by Brazilian rosewood and the quebracho tree; also predominant are the wacho white and black algarrobo trees ('' Prosopis alba'' and ''Prosopis nigra''). Savannah-like areas exist in the drier regions nearer the Andes. Aquatic plants thrive in the wetlands of Argentina. In central Argentina the ''humid pampas'' are a true tallgrass prairie ecosystem. In Argentina forest cover is around 10% of the total land area, equivalent to 28,573,000 hectares (ha) of forest in 2020, down from 35,204,000 ha in 1990. In 2020, naturally regenerating forest covered 27,137,000 ha and planted forest covered 1,436,000 ha. Of the naturally regenerating forest 0% was reported to be primary forest (consisting of native tree species with no clearly visible indications of human activity) and around 7% o ...

Enzymatic Activity
Enzyme assays are laboratory methods for measuring enzymatic activity. They are vital for the study of enzyme kinetics and enzyme inhibition. Enzyme units The quantity or concentration of an enzyme can be expressed in molar amounts, as with any other chemical, or in terms of activity in enzyme units. Enzyme activity Enzyme activity is a measure of the quantity of active enzyme present and is thus dependent on various physical conditions, ''which should be specified''. It is calculated using the following formula: :\mathrm=\mathrm_\text=\mathrm\times\mathrm where :\mathrm = Enzyme activity :\mathrm_\text = Moles of substrate converted per unit time :\mathrm = Rate of the reaction :\mathrm = Reaction volume The SI unit is the katal, 1 katal = 1 mol s−1 (mole per second), but this is an excessively large unit. A more practical and commonly used value is enzyme unit (U) = 1 μmol min−1 (micromole per minute). 1 U corresponds to 16.67 nanokatals. Enzyme activity as giv ...

Homeostasis
In biology, homeostasis (British English, British also homoeostasis; ) is the state of steady internal physics, physical and chemistry, chemical conditions maintained by organism, living systems. This is the condition of optimal functioning for the organism and includes many variables, such as body temperature and fluid balance, being kept within certain pre-set limits (homeostatic range). Other variables include the pH of extracellular fluid, the concentrations of sodium, potassium, and calcium ions, as well as the blood sugar level, and these need to be regulated despite changes in the environment, diet, or level of activity. Each of these variables is controlled by one or more regulators or homeostatic mechanisms, which together maintain life. Homeostasis is brought about by a natural resistance to change when already in optimal conditions, and equilibrium is maintained by many regulatory mechanisms; it is thought to be the central motivation for all organic action.
