Pyriproxyfen
Pyriproxyfen is a pesticide which is found to be effective against a variety of insects. It was introduced to the US in 1996, to protect cotton crops against whitefly. It has also been found useful for protecting other crops. It is also used as a prevention for flea control on household pets, for killing indoor and outdoor ants and roaches. Methods of application include aerosols, bait, carpet powders, foggers, shampoos and pet collars. Pyriproxyfen is a juvenile hormone analog ( IRAC group 7C) and an insect growth regulator. It prevents larvae from developing into adulthood and thus rendering them unable to reproduce. In the US, pyriproxyfen is often marketed under the trade name Nylar, and is one of two active ingredients in Advantage II. In Europe, pyriproxyfen is known under the brand names Cyclio ( Virbac) and Exil Flea Free TwinSpot (Emax). Toxicity in mammals Pyriproxyfen has low acute toxicity. According to WHO and FAO, at elevated doses exceeding 5000 mg/kg of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insecticide Resistance Action Committee
The Insecticide Resistance Action Committee (IRAC) was formed in 1984 and works as a specialist technical group of the industry association CropLife to be able to provide a coordinated industry response to prevent or delay the development of insecticide resistance in insect, mite and nematode pests. IRAC strives to facilitate communication and education on insecticide and traits resistance as well as to promote the development and facilitate the implementation of insecticide resistance management strategies. IRAC is recognised by the Food and Agriculture Organization (FAO) and the World Health Organization (WHO) of the United Nations as an advisory body on matters pertaining to insecticide resistance. Pesticideresistance.org is a database financed by IRAC, US Department of Agriculture, and others. Sponsors IRAC's sponsors are: ADAMA, BASF, Bayer CropScience, Corteva, FMC, Mitsui Chemicals, Nihon Nohyaku, Sumitomo Chemical, Syngenta and UPL. Mode of action classification ...

Insect
Insects (from Latin ') are Hexapoda, hexapod invertebrates of the class (biology), class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (Insect morphology#Head, head, Thorax (insect anatomy), thorax and abdomen (insect anatomy), abdomen), three pairs of jointed Arthropod leg, legs, compound eyes, and a pair of antenna (biology), antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a insect brain, brain and a ventral nerve cord. Most insects reproduce Oviparous, by laying eggs. Insects Respiratory system of insects, breathe air through a system of Spiracle (arthropods), paired openings along their sides, connected to Trachea#Invertebrates, small tubes that take air directly to the tissues. The blood therefore does not carry oxygen; it is only partly contained in ves ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zika Virus
Zika virus (ZIKV; pronounced or ) is a member of the virus family ''Flaviviridae''. It is spread by daytime-active ''Aedes'' mosquitoes, such as '' A. aegypti'' and '' A. albopictus''. Its name comes from the Ziika Forest of Uganda, where the virus was first isolated in 1947. Zika virus shares a genus with the dengue, yellow fever, Japanese encephalitis, and West Nile viruses. Since the 1950s, it has been known to occur within a narrow equatorial belt from Africa to Asia. From 2007 to , the virus spread eastward, across the Pacific Ocean to the Americas, leading to the 2015–2016 Zika virus epidemic. The infection, known as Zika fever or Zika virus disease, often causes no or only mild symptoms, similar to a very mild form of dengue fever. While there is no specific treatment, paracetamol (acetaminophen) and rest may help with the symptoms. Zika can spread from a pregnant woman to her baby. This can result in microcephaly, severe brain malformations, and other b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Physiochemical
Biochemistry, or biological chemistry, is the study of chemical processes within and relating to living organisms. A sub-discipline of both chemistry and biology, biochemistry may be divided into three fields: structural biology, enzymology, and metabolism. Over the last decades of the 20th century, biochemistry has become successful at explaining living processes through these three disciplines. Almost all areas of the life sciences are being uncovered and developed through biochemical methodology and research. Voet (2005), p. 3. Biochemistry focuses on understanding the chemical basis that allows biological molecules to give rise to the processes that occur within living cells and between cells,Karp (2009), p. 2. in turn relating greatly to the understanding of tissues and organs as well as organism structure and function.Miller (2012). p. 62. Biochemistry is closely related to molecular biology, the study of the molecular mechanisms of biological phenomena.Astbury (1961) ...

DPT Vaccine
The DPT vaccine or DTP vaccine is a class of combination vaccines to protect against three infectious diseases in humans: diphtheria, pertussis (whooping cough), and tetanus (lockjaw). The vaccine components include diphtheria and tetanus toxoids, and either killed whole cells of the bacterium that causes pertussis or pertussis antigens. The term toxoid refers to vaccines which use an inactivated toxin produced by the pathogen which they are targeted against to generate an immune response. In this way, the toxoid vaccine generates an immune response which is targeted against the toxin which is produced by the pathogen and causes disease, rather than a vaccine which is targeted against the pathogen itself. The whole cells or antigens will be depicted as either "DTwP" or "DTaP", where the lower-case "w" indicates whole-cell inactivated pertussis and the lower-case "a" stands for "acellular". In comparison to alternative vaccine types, such as live attenuated vaccines, the DTP ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antivaccine
Anti-vaccine activism, which collectively constitutes the "anti-vax" movement, is a set of organized activities expressing opposition to vaccination, and these collaborating networks have often sought to increase vaccine hesitancy by disseminating vaccine misinformation and/or forms of active disinformation. As a social movement, it has utilized multiple tools both within traditional news media and also through various forms of online communication. Activists have primarily (though far from entirely) focused on issues surrounding children, with vaccination of the young receiving pushback, and they have sought to expand beyond niche subgroups into national political debates. Ideas that would eventually coalesce into anti-vaccine activism have existed for longer than vaccines themselves. Various myths and conspiracy theories (alongside outright disinformation and misinformation) have been spread by the anti-vaccination movement and fringe doctors. These have been spread in a ...

Conspiracy Theory
A conspiracy theory is an explanation for an event or situation that asserts the existence of a conspiracy (generally by powerful sinister groups, often political in motivation), when other explanations are more probable.Additional sources: * * * * The term generally has a negative connotation, implying that the appeal of a conspiracy theory is based in prejudice, emotional conviction, or insufficient evidence. A conspiracy theory is distinct from a conspiracy; it refers to a hypothesized conspiracy with specific characteristics, including but not limited to opposition to the mainstream consensus among those who are qualified to evaluate its accuracy, such as scientists or historians. Conspiracy theories tend to be internally consistent and correlate with each other; they are generally designed to resist falsification either by evidence against them or a lack of evidence for them. They are reinforced by circular reasoning: both evidence against the conspiracy ''and'' absenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
