Stem Cell Laws And Policy In The United States
Stem cell laws and policy in the United States have had a complicated legal and political history. Science background Stem cells are cells found in all multi-cellular organisms. They were isolated in mice in 1981, and in humans in 1998.John Ydstie and Joe Palca, "Embryonic Stem Cells Made Without Embryos," ''NPR'', November 21, 2007, found aNPR website story of 11-21-09 Retrieved April 8, 2009. In humans there are many types of stem cells, each with varying levels of potency. Potency is a measure of a cell's differentiation potential, or the number of other cell types that can be made from that stem cell. Embryonic stem cells are pluripotent stem cells derived from the inner cell mass of the blastocyst. These stem cells can differentiate into all other cells in the human body and are the subject of much scientific research. However, since they must be derived from early human embryos their production and use in research has been a hotly debated topic. Stem cell treatments ar ...

Stem Cell
In multicellular organisms, stem cells are undifferentiated or partially differentiated cells that can differentiate into various types of cells and proliferate indefinitely to produce more of the same stem cell. They are the earliest type of cell in a cell lineage. They are found in both embryonic and adult organisms, but they have slightly different properties in each. They are usually distinguished from progenitor cells, which cannot divide indefinitely, and precursor or blast cells, which are usually committed to differentiating into one cell type. In mammals, roughly 50–150 cells make up the inner cell mass during the blastocyst stage of embryonic development, around days 5–14. These have stem-cell capability. ''In vivo'', they eventually differentiate into all of the body's cell types (making them pluripotent). This process starts with the differentiation into the three germ layers – the ectoderm, mesoderm and endoderm – at the gastrulation stage. However ...

Louise Brown
Louise Joy Brown (born 25 July 1978) is an English woman who was the first human to have been born after conception by ''in vitro'' fertilisation experiment (IVF). Her birth, following a procedure pioneered in Britain, has been lauded among "the most remarkable medical breakthroughs of the 20th Century". Birth and early life Louise Joy Brown was born at Oldham General Hospital, Lancashire, by planned Caesarean section performed by registrar John Webster. She weighed 5 pounds, 12 ounces (2.608 kg) at birth. Her parents, Lesley and John Brown, had been trying to conceive naturally for nine years, but Lesley faced complications of blocked fallopian tubes."World's first IVF baby marks 30th birthday" |
Tennessee

Senate Majority Leader
The positions of majority leader and minority leader are held by two United States senators and members of the party leadership of the United States Senate. They serve as the chief spokespersons for their respective political parties holding the majority and the minority in the United States Senate. They are each elected as majority leader and minority leader by the senators of their party caucuses: the Senate Democratic Caucus and the Senate Republican Conference. By Senate precedent, the presiding officer gives the majority leader priority in obtaining recognition to speak on the floor of the Senate. The majority leader serves as the chief representative of their party in the Senate, and is considered the most powerful member of the Senate. They also serve as the chief representative of their party in the entire Congress if the House of Representatives, and thus the office of the speaker of the House, is controlled by the opposition party. The Senate's executive and legislat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
In Vitro Fertilization
In vitro fertilisation (IVF) is a process of fertilisation where an egg is combined with sperm in vitro ("in glass"). The process involves monitoring and stimulating an individual's ovulatory process, removing an ovum or ova (egg or eggs) from their ovaries and letting sperm fertilise them in a culture medium in a laboratory. After the fertilised egg (zygote) undergoes embryo culture for 2–6 days, it is transferred by catheter into the uterus, with the intention of establishing a successful pregnancy. IVF is a type of assisted reproductive technology used for infertility treatment, gestational surrogacy, and, in combination with pre-implantation genetic testing, avoiding transmission of genetic conditions. A fertilised egg from a donor may implant into a surrogate's uterus, and the resulting child is genetically unrelated to the surrogate. Some countries have banned or otherwise regulate the availability of IVF treatment, giving rise to fertility tourism. Restrictions ...

Factions In The Republican Party (United States)
The Republican Party in the United States includes several factions, or wings. During the 19th century, Republican factions included the Half-Breeds, who supported civil service reform; the Radical Republicans, who advocated the immediate and total abolition of slavery; and the Stalwarts, who supported machine politics. In the 20th century, Republican factions included the Progressive Republicans, the Reagan coalition, and the liberal Rockefeller Republicans. In the 21st century, Republican factions include conservatives (represented in Congress by the Republican Study Committee and the Freedom Caucus), moderates (represented in Congress by the Republican Governance Group), libertarians (represented in Congress by the Republican Liberty Caucus). During and after the presidency of Donald Trump, Trumpist and anti-Trumpist factions arose within the Republican Party. Modern factions During the presidency of Barack Obama, the Republican Party experienced internal conflict between ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Congress
The United States Congress is the legislature of the federal government of the United States. It is bicameral, composed of a lower body, the House of Representatives, and an upper body, the Senate. It meets in the U.S. Capitol in Washington, D.C. Senators and representatives are chosen through direct election, though vacancies in the Senate may be filled by a governor's appointment. Congress has 535 voting members: 100 senators and 435 representatives. The U.S. vice president has a vote in the Senate only when senators are evenly divided. The House of Representatives has six non-voting members. The sitting of a Congress is for a two-year term, at present, beginning every other January. Elections are held every even-numbered year on Election Day. The members of the House of Representatives are elected for the two-year term of a Congress. The Reapportionment Act of 1929 establishes that there be 435 representatives and the Uniform Congressional Redistricting Act requires ...

Dickey–Wicker Amendment
The Dickey–Wicker Amendment is the name of an appropriation bill rider attached to a bill passed by United States Congress in 1995, and signed by former President Bill Clinton, which prohibits the United States Department of Health and Human Services (HHS) from using appropriated funds for the creation of human embryos for research purposes or for research in which human embryos are destroyed. HHS funding includes the funding for the National Institutes of Health (NIH). It is named after Jay Dickey and Roger Wicker, two Republican Representatives. Technically, the Dickey Amendment is a rider to other legislation, which amends the original legislation. The rider receives its name from the name of the Congressman that originally introduced the amendment, Representative Dickey. The Dickey amendment language has been added to each of the Labor, HHS, and Education appropriations acts for fiscal years 1997 through 2009. The original rider can be found in Section 128 of P.L. 104–99. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Library Of Congress Control Number
The Library of Congress Control Number (LCCN) is a serially based system of numbering cataloged records in the Library of Congress, in the United States. It is not related to the contents of any book, and should not be confused with Library of Congress Classification (LCC). History The LCCN numbering system has been in use since 1898, at which time the acronym LCCN originally stood for Library of Congress Card Number. It has also been called the Library of Congress Catalog Card Number, among other names. The Library of Congress prepared cards of bibliographic information for their library catalog and would sell duplicate sets of the cards to other libraries for use in their catalogs. This is known as centralized cataloging. Each set of cards was given a serial number to help identify it. Although most of the bibliographic information is now electronically created, stored, and shared with other libraries, there is still a need to identify each unique record, and the LCCN cont ...
