Who invented Teratology?

Who invented Teratology?

Results: During the past 40 years, we have developed the scientific basis to prevent birth defects caused by rubella, alcoholism, and folate deficiency, as well as many other prenatal exposures. A history should record and honor the past, help plan for the future, and entertain the reader.

What causes teratogenesis?

Teratogens include some medications, recreational drugs, tobacco products, chemicals, alcohol, certain infections, and in some cases, health problems such as uncontrolled diabetes in pregnant people. Exposure to a teratogen can occur through ingestion or environmental exposure during pregnancy.

What are 4 teratogens?

Teratogens are classified into four types: physical agents, metabolic conditions, infection, and finally, drugs and chemicals. The word teratogen originates from the Greek word for monster, teratos.

What causes Teratology?

Causes of teratogenesis can broadly be classified as: Toxic substances, such as, for humans, drugs in pregnancy and environmental toxins in pregnancy. Potassium iodide is a possible teratogen.

Is Covid 19 teratogenic?

According to RCOG, there is currently not enough data to provide a correlation between the risk of miscarriage and COVID-19 or that the virus is teratogenic [27]. The possibility of vertical transmission needs further research as there have been conflicting results so far.

What teratology means?

Teratology is derived from the Greek noun teras, meaning monster, and historically has referred to the study of malformations early in life that result from exposure to chemicals such as mercury, lead, and other complex compounds.

When do teratogens have their greatest effects?

The embryonic period, during which organogenesis takes place, occurs between implantation at around 14 days to around 60 days postconception. This is usually the most sensitive period to teratogenesis when exposure to a teratogenic agent has the greatest likelihood of producing a malformation.

How did the Internet start?

The Internet started in the 1960s as a way for government researchers to share information. Computers in the ’60s were large and immobile and in order to make use of information stored in any one computer, one had to either travel to the site of the computer or have magnetic computer tapes sent through the conventional postal system.

What is the history of the Internet research program?

In 1983, when Barry Leiner took over management of the Internet research program at DARPA, he and Clark recognized that the continuing growth of the Internet community demanded a restructuring of the coordination mechanisms.

What is the history of Internet email?

In 1971 Ray Tomlinson created what was to become the standard Internet electronic mail addressing format, using the @ sign to separate mailbox names from host names. A number of protocols were developed to deliver messages among groups of time-sharing computers over alternative transmission systems, such as UUCP and IBM ‘s VNET email system.

Who invented the TCP and IP protocol?

Bob Kahn, at ARPA, and Vint Cerf, at Stanford University, published research in 1974 that evolved into the Transmission Control Protocol (TCP) and Internet Protocol (IP), the two protocols of the Internet protocol suite. The design included concepts from the French CYCLADES project directed by Louis Pouzin.
