Clausena Anisata
:''Should not be confused with syzygium anisatum, a tree native to eastern Australian rainforests, used as a culinary herb.'' ''Clausena anisata'' ( Willd.) Hook.f. ex Benth. is a deciduous shrub or small tree, belonging to the Rutaceae or Citrus family, and widespread in the Afrotropical realm or Sub-Saharan Africa, but absent from the drier regions. It is also found in tropical and South-East Asia, growing in India and Sri Lanka and extending as far as Queensland in north-eastern Australia and some Pacific islands. It is cultivated in Malaysia and Indonesia.

Chavicol
Chavicol (''p''-allylphenol) is a natural phenylpropene, a type of organic compound. Its chemical structure consists of a benzene ring substituted with a hydroxy group and a propenyl group. It is a colorless liquid found together with terpenes in betel oil. Properties and reactions Chavicol is miscible with alcohol, ether, and chloroform. Dimerization of chavicol gives the neo-lignan magnolol. Uses Chavicol is used as an odorant in perfumery and as a flavor. It is found in many essential oils, including anise and Gardenia. Biosynthesis Chavicol is formed in sweet basil (''Ocimum Basilicum'') by the phenylpropanoid pathway via p-coumaryl alcohol. The allylic alcohol in p-coumaryl alcohol is converted into a leaving group. This then leaves thus forming a cation, this cation can be reagrded as a quinone methide which then is reduced by NADPH to form either anol or chavicol.Daniel G. Vassao, David R.

Animal Testing On Rodents
Rodents are commonly used in animal testing, particularly mice and rats, but also guinea pigs, hamsters, gerbils and others. Mice are the most commonly used vertebrate species, due to their availability, size, low cost, ease of handling, and fast reproduction rate. __TOC__ Statistics In the UK in 2015, there were 3.33 million procedures on rodents (80% of total procedures that year). The most common species used were mice (3.03 million procedures, or 73% of total) and rats (268,522, or 6.5%). Other rodents species included guinea pigs (21,831 / 0.7%), hamsters (1,500 / 0.04%) and gerbils (278 / 0.01%). In the U.S., the numbers of rats and mice used are not reported, but estimates range from around 11 million to approximately 100 million.

Genotoxic
Genotoxicity is the property of chemical agents that damage the genetic information within a cell causing mutations, which may lead to cancer. While genotoxicity is often confused with mutagenicity, all mutagens are genotoxic, but some genotoxic substances are not mutagenic. The alteration can have direct or indirect effects on the DNA: the induction of mutations, mistimed event activation, and direct DNA damage leading to mutations. The permanent, heritable changes can affect either somatic cells of the organism or germ cells to be passed on to future generations. Cells prevent expression of the genotoxic mutation by either DNA repair or apoptosis; however, the damage may not always be fixed leading to mutagenesis. To assay for genotoxic molecules, researchers assay for DNA damage in cells exposed to the toxic substrates. This DNA damage can be in the form of single- and double-strand breaks, loss of excision repair, cross-linking, alkali-labile sites, point mutations, and structura ...

Carcinogenic
A carcinogen is any substance, radionuclide, or radiation that promotes carcinogenesis (the formation of cancer). This may be due to the ability to damage the genome or to the disruption of cellular metabolic processes. Several radioactive substances are considered carcinogens, but their carcinogenic activity is attributed to the radiation, for example gamma rays and alpha particles, which they emit. Common examples of non-radioactive carcinogens are inhaled asbestos, certain dioxins, and tobacco smoke. Although the public generally associates carcinogenicity with synthetic chemicals, it is equally likely to arise from both natural and synthetic substances. Carcinogens are not necessarily immediately toxic; thus, their effect can be insidious. Carcinogens, as mentioned, are agents in the environment capable of contributing to cancer growth. Carcinogens can be categorized into two different types: activation-dependent and activation-independent, and each nature impacts the ...
