United Kingdom Tainted Blood Scandal
In the 1970s and 1980s, a large number of people – most of whom had haemophilia – were infected with hepatitis C and HIV, the virus that leads to acquired immune deficiency syndrome (AIDS), as a result of receiving contaminated clotting factor products. In the United Kingdom, these were supplied by the National Health Service (NHS). The Haemophilia Society estimates that around 4,700 people with bleeding disorders were infected, with some estimates as high as 6,000. As of August 2022, at least 2,400 people have died from the use of contaminated factor VIII and factor IX clotting agents and the viruses they transmitted. More broadly, contaminated blood transfusions and blood products provided by the NHS are thought to have infected around 25,000–30,000 people with viruses during the period. People with haemophilia were principally infected via the plasma-derived product known as factor VIII, a processed pharmaceutical product sourced from the United States and elsewhere. Th ...

Coagulation
Coagulation, also known as clotting, is the process by which blood changes from a liquid to a gel, forming a blood clot. It potentially results in hemostasis, the cessation of blood loss from a damaged vessel, followed by repair. The mechanism of coagulation involves activation, adhesion and aggregation of platelets, as well as deposition and maturation of fibrin. Coagulation begins almost instantly after an injury to the endothelium lining a blood vessel. Exposure of blood to the subendothelial space initiates two processes: changes in platelets, and the exposure of subendothelial tissue factor to plasma factor VII, which ultimately leads to cross-linked fibrin formation. Platelets immediately form a plug at the site of injury; this is called ''primary hemostasis. Secondary hemostasis'' occurs simultaneously: additional coagulation (clotting) factors beyond factor VII ( listed below) respond in a cascade to form fibrin strands, which strengthen the platelet plug. Disorders of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cutter Laboratories
Cutter Laboratories was a family-owned pharmaceutical company located in Berkeley, California, founded by Edward Ahern Cutter in 1897. Cutter's early products included anthrax vaccine, hog cholera (swine fever) virus, and anti-hog cholera serum—and eventually a hog cholera vaccine. The hog cholera vaccine was the first tissue culture vaccine, human or veterinary, ever produced. The company expanded considerably during World War II as a consequence of government contracts for blood plasma and penicillin. After Edward Cutter's death, his three sons—Dr. Robert K. Cutter (president), Edward "Ted" A. Cutter Jr. (vice-president), and Frederick A. Cutter—ran the company. In the next generation Robert's son David followed his father as president of the company. The Bayer pharmaceutical company bought Cutter Laboratories in 1974. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bayer
Bayer AG (, commonly pronounced ; ) is a German multinational corporation, multinational pharmaceutical and biotechnology company and one of the largest pharmaceutical companies in the world. Headquartered in Leverkusen, Bayer's areas of business include pharmaceuticals; consumer healthcare products, agricultural chemicals, seeds and biotechnology products. The company is a component of the Euro Stoxx 50 stock market index. Bayer was founded in 1863 in Barmen as a partnership between dye salesman Friedrich Bayer and dyer Friedrich Weskott. As was common in this era, the company was established as a dyestuffs producer. The versatility of aniline chemistry led Bayer to expand their business into other areas, and in 1899 Bayer launched the compound acetylsalicylic acid under the trademarked name Aspirin. In 1904 Bayer received a trademark for the "Bayer Cross" logo, which was subsequently stamped onto each aspirin tablet, creating an iconic product that is still sold by Bayer. Ot ...

Plasmapheresis
Plasmapheresis (from the Greek πλάσμα, ''plasma'', something molded, and ἀφαίρεσις ''aphairesis'', taking away) is the removal, treatment, and return or exchange of blood plasma or components thereof from and to the blood circulation. It is thus an extracorporeal therapy, a medical procedure performed outside the body. Three general types of plasmapheresis can be distinguished: * ''Autologuous'', removing blood plasma, treating it in some way, and returning it to the same person, as a therapy. * ''Exchange'', a patient's blood plasma is removed, while blood products are given in replacement. This type is called plasma exchange (PE, PLEX, or PEX) or plasma exchange therapy (PET). The removed plasma is discarded and the patient receives replacement donor plasma, albumin, or a combination of albumin and saline (usually 70% albumin and 30% saline). * ''Donation'', removing blood plasma, separating its components, and returning some of them to the same person, while ho ...

Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

Luckner Cambronne
Luckner Cambronne (30 October 193024 September 2006) was a high-ranking political figure in François Duvalier's regime in Haiti. Cambronne was born the son of a poor preacher and had a career as a bank teller. His alliance with François Duvalier, the Haitian politician who became President of Haiti, led to Cambronne's rising to the number two position in power. In his political career, Cambronne started out as a messenger for Duvalier. After developing a reputation for enforcement and cruelty, he quickly rose in his administration. He was appointed Minister of the Interior and National Defense under Duvalier. Cambronne became Duvalier's second in command and head of his fearsome private militia, popularly known as the ''Tonton Macoutes''. Cambronne's reign was characterized by his embezzlement campaign: the use of public funds for his personal businesses and enterprises. As head of the ''Tonton Macoutes'', Cambronne led a campaign of state terrorism against all oppos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protein Production
Protein production is the biotechnological process of generating a specific protein. It is typically achieved by the manipulation of gene expression in an organism such that it expresses large amounts of a recombinant gene. This includes the transcription of the recombinant DNA to messenger RNA (mRNA), the translation of mRNA into polypeptide chains, which are ultimately folded into functional proteins and may be targeted to specific subcellular or extracellular locations. Protein production systems (also known as expression systems) are used in the life sciences, biotechnology, and medicine. Molecular biology research uses numerous proteins and enzymes, many of which are from expression systems; particularly DNA polymerase for PCR, reverse transcriptase for RNA analysis, restriction endonucleases for cloning, and to make proteins that are screened in drug discovery as biological targets or as potential drugs themselves. There are also significant applications for expressi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hemarthrosis
Hemarthrosis is a bleeding into joint spaces. It is a common feature of hemophilia. Causes It usually follows injury but occurs mainly in patients with a predisposition to hemorrhage such as those being treated with warfarin (or other anticoagulants) and patients with hemophilia. It can be associated with knee joint arthroplasty. It has also been reported as a part of hemorrhagic syndrome in the Crimean-Congo Hemorrhagic Fever, suggesting a viral cause to the bleeding in a joint space. Diagnosis Hemarthrosis is diagnosed through the methods listed below: A physical examination is the first step, the joints of the patient are moved and bent to study the functioning. Synovial Fluid analysis is another method to diagnose Hemarthrosis. It involves a small needle being inserted into the joint to draw the fluid. Reddish-colored hue of the sample is an indication of the blood being present. Imaging tests are normally done. The tests also include MRI, Ultrasound and X-ray test, which ...
