Scolopendra Viridicornis
''Scolopendra viridicornis'' is a species of centipede in the family Scolopendridae which can be found within the Amazon rainforest, the type locality being in Brazil. Due to the geographic distribution of this species it is known as the Amazonian giant centipede. Behavior and diet As with the vast majority of species in this genus, Scolopendra viridicornis is carnivorous. It hunts actively, seizing any prey items small enough to be overpowered. Due to the large size of this centipede, its diet not only includes arthropods but may also consist of small vertebrates such as rodents, frogs, snakes and lizards. The centipede typically seizes and restrains prey with help from a muscular body and numerous legs, then delivers a venomous bite to subdue and kill the prey animal. It has also been known to scavenge when the opportunity presents itself. Scolopendra viridicornis is quite quick to flee when disturbed by a predator, running away with impressive speed. If pursued the centipede ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Newport
George Newport Fellow of the Royal Society, FRS (4 February 1803, Canterbury – 7 April 1854, London) was a prominent English entomologist. He is especially noted for his studies utilizing the microscope and his skills in dissection. Biography He was the first of four children of William Newport (1777-1843), a local wheelwright, and Sarah Gillham. He was educated at London University and at the London College of Surgeons, College of Surgeons. He was President of the Entomological Society of London (1843–1844) and also a member of the Ray Society. Newport was awarded with the Royal Medal 1836 and with the Royal Society Bakerian Medal 1841. He is buried in Kensal Green Cemetery, London. Works He was one of the most skilled anatomists of his time, and his researches on the structure of insects and other arthropods are notable.

Centipede
Centipedes (from New Latin , "hundred", and Latin , " foot") are predatory arthropods belonging to the class Chilopoda (Ancient Greek , ''kheilos'', lip, and New Latin suffix , "foot", describing the forcipules) of the subphylum Myriapoda, an arthropod group which includes millipedes and other multi-legged animals. Centipedes are elongated segmented (metameric) creatures with one pair of legs per body segment. All centipedes are venomous and can inflict painful bites, injecting their venom through pincer-like appendages known as forcipules. Despite the name, centipedes can have a varying number of legs, ranging from 30 to 382. Centipedes always have an odd number of pairs of legs; no centipede has exactly 100. Like spiders and scorpions, centipedes are predominantly carnivorous. Their size ranges from a few millimetres in the smaller lithobiomorphs and geophilomorphs to about in the largest scolopendromorphs. Centipedes can be found in a wide variety of environments. They ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scolopendridae
Scolopendridae (or, in older documents, Scolopendridæ) is a family of large centipedes (class Chilopoda). Nearly all species in this family have four ocelli ( simple eyes) on each side of the head and only 21 pairs of legs, but there are exceptions: two scolopendrid species feature more legs (''Scolopendropsis bahiensis'', with 21 or 23 leg pairs, and ''S. duplicata'', with 39 or 43 leg pairs), and some scolopendrid species are eyeless and blind (e.g., ''Cormocephalus sagmus'', ''C. pyropygus'', and ''C. delta''). Three Asian members of this family, ''Scolopendra cataracta'', ''Scolopendra paradoxa'', and ''Scolopendra alcyona,'' are known to show amphibious behaviour. Two other species, ''Scolopendra hardwickei'' and ''Hemiscolopendra marginata,'' are known to show sexual dimorphism in the composition of their venom.

Analgesic
An analgesic drug, also called simply an analgesic (American English), analgaesic (British English), pain reliever, or painkiller, is any member of the group of drugs used to achieve relief from pain (that is, analgesia or pain management). It is typically used to induce cooperation with a medical procedure. Analgesics are conceptually distinct from anesthetics, which temporarily reduce, and in some instances eliminate, sensation, although analgesia and anesthesia are neurophysiologically overlapping and thus various drugs have both analgesic and anesthetic effects. Analgesic choice is also determined by the type of pain: For neuropathic pain, traditional analgesics are less effective, and there is often benefit from classes of drugs that are not normally considered analgesics, such as tricyclic antidepressants and anticonvulsants. Various analgesics, such as many NSAIDs, are available over the counter in most countries, whereas various others are prescription drugs owing ...

Antimicrobial
An antimicrobial is an agent that kills microorganisms or stops their growth. Antimicrobial medicines can be grouped according to the microorganisms they act primarily against. For example, antibiotics are used against bacteria, and antifungals are used against fungi. They can also be classified according to their function. Agents that kill microbes are microbicides, while those that merely inhibit their growth are called bacteriostatic agents. The use of antimicrobial medicines to treat infection is known as antimicrobial chemotherapy, while the use of antimicrobial medicines to prevent infection is known as antimicrobial prophylaxis. The main classes of antimicrobial agents are disinfectants (non-selective agents, such as bleach), which kill a wide range of microbes on non-living surfaces to prevent the spread of illness, antiseptics (which are applied to living tissue and help reduce infection during surgery), and antibiotics (which destroy microorganisms within the body).

Cytotoxicity
Cytotoxicity is the quality of being toxic to cells. Examples of toxic agents are an immune cell or some types of venom, e.g. from the puff adder (''Bitis arietans'') or brown recluse spider (''Loxosceles reclusa''). Cell physiology Treating cells with the cytotoxic compound can result in a variety of cell fates. The cells may undergo necrosis, in which they lose membrane integrity and die rapidly as a result of cell lysis. The cells can stop actively growing and dividing (a decrease in cell viability), or the cells can activate a genetic program of controlled cell death (apoptosis). Cells undergoing necrosis typically exhibit rapid swelling, lose membrane integrity, shut down metabolism, and release their contents into the environment. Cells that undergo rapid necrosis in vitro do not have sufficient time or energy to activate apoptotic machinery and will not express apoptotic markers. Apoptosis is characterized by well defined cytological and molecular events including a change i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Blood Cell
Red blood cells (RBCs), also referred to as red cells, red blood corpuscles (in humans or other animals not having nucleus in red blood cells), haematids, erythroid cells or erythrocytes (from Greek ''erythros'' for "red" and ''kytos'' for "hollow vessel", with ''-cyte'' translated as "cell" in modern usage), are the most common type of blood cell and the vertebrate's principal means of delivering oxygen (O2) to the body tissues—via blood flow through the circulatory system. RBCs take up oxygen in the lungs, or in fish the gills, and release it into tissues while squeezing through the body's capillaries. The cytoplasm of a red blood cell is rich in hemoglobin, an iron-containing biomolecule that can bind oxygen and is responsible for the red color of the cells and the blood. Each human red blood cell contains approximately 270 million hemoglobin molecules. The cell membrane is composed of proteins and lipids, and this structure provides properties essential for physiolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scolopendra
''Scolopendra'' (through Latin from Greek , ''skolopendra'') is a species-rich genus of large tropical centipedes of the family Scolopendridae. Description The genus ''Scolopendra'' contains many species of centipedes found across the world's tropics and warmer temperate areas. The species vary considerably in coloration and size. ''Scolopendra'' are mostly very large centipedes. The largest species found in tropical climates can exceed and are the largest living centipedes in the world. All ''Scolopendra'' species can deliver a painful bite, injecting venom through their forcipules, which are not fangs or other mouthparts; rather, these are modified legs on the first body segment. Ecology ''Scolopendra'' are active predators, feeding primarily on insects and other invertebrates. Larger specimens have been observed preying on frogs, tarantulas, lizards, birds, snakes, rodents, and even bats. Two southeast Asian species, '' S. cataracta'' and '' S. paradoxa'', are amphibious, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthropods Of India
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and cuticle made of chitin, often mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior organs; it has an open circulatory system. Like their exteriors, the internal organs of arthropods are generally built of repeated segments. Their nervous system is "ladde ...
