Teratogen

Factors of teratogenicity are around pregnant women. Please look at an ordinary house and hold a toothpaste on the bottle. Most people use toothpaste at home every day and use toothpaste everyday, but if they consume all the chemicals they are considered teratogenic substances. Teratogenic factors affect embryogenesis and counselors help prevent exposure to teratogenic substances

Almost all artificial substances can be considered to some extent teratogenic substances. However, the key question is which level of matter is considered teratogenic factor, since it is formally classified as a teratogenic factor.

Teratogenicity is the occurrence of congenital anomalies caused by exposure to substances known as teratogenic substances during development. Many teratogenic substances are mutagens, as they may cause mutations in DNA. An example of a teratogen is thalidomide. Thalidomide was used to treat morning sickness in pregnant women in the 1950s. It was discovered later that it causes birth defects. In this case, it destroys the development process and causes abnormalities that affect normal development. Mutagenesis can occur in many different ways, but there are DNA repair mechanisms that help maintain genomic integrity. The mechanism called nucleotide excision repair involves identification and removal of damaged DNA by nicking in the presence of a point mutation, removal of damaged nucleotide sequence, resynthesis to add correct nucleotide, and incision. DNA DNA ligation for sealing the repaired DNA

Teratogenicity, also known as "teratogenicity", occurs when an infant is exposed to a substance causing an abnormality during pregnancy. Infants are very sensitive early in pregnancy where all organs are developing. Teratogenic substances include alcohol, drugs, lead, high levels of radiation exposure, and certain drugs, infectious diseases, and toxic substances. Vector screening is a blood test that attempts to determine if any of the parents are genetically altering to infect infants with heritable diseases. Saliva samples are also possible. The best time to do this screening is before pregnancy, but you can do it even during pregnancy. This screen can check several states at the same time, but it is currently impossible to screen all diseases that may be inherited.

Teratogenic substances are any environmental substances or substances (biological, chemical or physical) that may adversely affect developing fetuses. Exposure to teratogen during prenatal period significantly increases the risk of congenital deficiency. Several factors, including dose or exposure level, genetic, age of teratogenic substance, other adverse effects (eg some teratogenic substances or teratogenic substances and disorders) are caused by teratogenic damage It affects the degree. There are several known teratogens recommended for pregnant pregnant women, including alcohol, prescription drugs and / or illegal drugs and tobacco.
