Sir Frederick Grant Banting was a Canadian medical scientist, physician and Nobel laureate noted as the co-discoverer of insulin and its therapeutic potential. In 1923 Banting and John James Rickard Macleod received the Nobel Prize in Medicine. Banting shared the honours and award money with Dr. Charles Best; as of November 2018, who received the Nobel Prize at age 32, remains the youngest Nobel laureate in the area of Physiology/Medicine. In 1923 the Government of Canada granted Banting a lifetime annuity to continue his work. In 1934 he was knighted by King George V. Frederick Banting was born on November 14, 1891, in a farm house near Alliston, Ontario; the youngest of five children of William Thompson Banting and Margaret Grant, he attended public high school in Alliston. In 1910, he started at Victoria College, part of the University of Toronto, in the General Arts program. After failing his first year, he was accepted, he began medical school in September 1912. In 1914, he attempted to enter the army on August 16, again in October, but was refused due to poor eyesight.
Banting joined the army in 1915 and spent the summer training before returning to school. His class was fast-tracked to get more doctors into the war and so he graduated in December 1916 and reported for military duty the next day, he was wounded at the Battle of Cambrai in 1918. Despite his injuries, he helped other wounded men for sixteen hours, until another doctor told him to stop, he was awarded the Military Cross for heroism. In 1918, he was awarded the licence to practice medicine and midwifery by the Royal College of Physicians of London. Banting went to Toronto to complete his surgical training, he studied orthopedic medicine and, in 1919–1920, was Resident Surgeon at The Hospital for Sick Children. Banting was unable to gain a place on the hospital staff and so he decided to move to London, Ontario to set up a medical practice. From July 1920 to May 1921, he continued his general practice, while teaching orthopedics and anthropology part-time at the University of Western Ontario in London because his medical practice had not been successful.
From 1921 to 1922 he lectured in pharmacology at the University of Toronto. He received his M. D. degree in 1922, was awarded a gold medal. An article he read about the pancreas piqued Banting's interest in diabetes. Banting had to give a talk on the pancreas to one of his classes at the University of Western Ontario on November 1, 1920, he was therefore reading reports that other scientists had written. Research by Naunyn, Opie, Sharpey-Schafer, others suggested that diabetes resulted from a lack of a protein hormone secreted by the islets of Langerhans in the pancreas. Schafer had named this putative hormone "insulin"; the hormone was thought to control the metabolism of sugar. Attempts to extract insulin from ground-up pancreas cells were unsuccessful because of the destruction of the insulin by the proteolysis enzyme of the pancreas; the challenge was to find a way to extract insulin from the pancreas prior to its destruction. Moses Barron published an article in 1920 which described experimental closure of the pancreatic duct by ligature.
The procedure caused deterioration of the cells of the pancreas that secrete trypsin which breaks down insulin, but it left the islets of Langerhans intact. Banting realized. Once the trypsin-secreting cells had died, insulin could be extracted from the islets of Langerhans. Banting discussed this approach with J. J. R. Macleod, Professor of Physiology at the University of Toronto. Macleod provided the assistance of one of his students, Charles Best. Banting and Best, with the assistance of biochemist James Collip, began the production of insulin by this means; as the experiments proceeded, the required quantities could no longer be obtained by performing surgery on living dogs. In November 1921, Banting hit upon the idea of obtaining insulin from the fetal pancreas, he removed the pancreases from fetal calves at a William Davies slaughterhouse and found the extracts to be just as potent as those extracted from the dog pancreases. By December 1921, he had succeeded in extracting insulin from the adult pancreas.
Pork and beef would remain the primary commercial sources of insulin until they were replaced by genetically-engineered bacteria in the late 20th century. In spring of 1922, Banting established a private practice in Toronto and began to treat diabetic patients, his first American patient was Elizabeth Hughes Gossett, daughter of U. S. Secretary of State Charles Evans Hughes. Banting and Macleod were jointly awarded the 1923 Nobel Prize in Medicine. Banting split his half of the Prize money with Best, Macleod split the other half of the Prize money with James Collip. Banting was appointed Senior Demonstrator in Medicine at the University of Toronto in 1922; the following year he was elected to the new Banting and Best Chair of Medical Research, endowed by the Legislature of the Province of Ontario. He served as Honorary Consulting Physician to the Toronto General, the Hospital for Sick Children, the Toronto Western Hospital. At the Banting and Best Institute, he focused his research on silicosis and the mechanisms of drowning.
In 1938, Banting's interest in aviation medicine resulted in his participation with the Royal Canadian Air Force in research concerning the physiological problems encountered by pi
Danger is an upcoming Indian Bollywood horror thriller film and directed by Faisal Saif under his own banner Faith Pictures Inc. The film is inspired by true events of Gaya Hotel's brutal owner who killed people and used their meat to serve others.

Saif approached actor Aamir Khan's brother Faisal Khan to play the main lead role and Khan found the script exciting and became a part of it. Khan claimed that he worked hard on nailing the Gujrati accent required for the film. Vedita Pratap Singh and Saif's regular fixture Kavita Radheshyam were added to the cast. Television actor Nishant Pandey was approached along with Sony Charishta to play other lead characters in the film.
The principal photography of the film commenced sometime in September 2016 and wrapped up with Pakistani actress Meera's song in December 2016. On 23 December, the makers released the First Look poster of the film. News sites such as India.com praised the First Look poster by calling it "Aamir Khan's brother Faissal Khan's comeback film looks creepy AF!". Official page on Facebook
Factor VII is one of the proteins that causes blood to clot in the coagulation cascade. It is an enzyme of the serine protease class. A recombinant form of human factor VIIa has U. S. Food and Drug Administration approval for uncontrolled bleeding in hemophilia patients, it is sometimes used unlicensed in severe uncontrollable bleeding, although there have been safety concerns. A biosimilar form of recombinant activated factor VII is available, but does not play any considerable role in the market; the main role of factor VII is to initiate the process of coagulation in conjunction with tissue factor. Tissue factor is found on the outside of blood vessels - not exposed to the bloodstream. Upon vessel injury, tissue factor is exposed to the blood and circulating factor VII. Once bound to TF, FVII is activated to FVIIa by different proteases, among which are thrombin, factor Xa, IXa, XIIa, the FVIIa-TF complex itself; the complex of factor VIIa with TF catalyzes the conversion of factor IX and factor X into the active proteases, factor IXa and factor Xa, respectively.
The action of the factor is impeded by tissue factor pathway inhibitor, released immediately after initiation of coagulation. Factor VII, discovered around 1950, is vitamin K-dependent and produced in the liver. Use of warfarin or similar anticoagulants decreases hepatic synthesis of FVII. Factor VII shares a common domain architecture with factors IX and X; the gene for factor VII is located on chromosome 13. Factor VII deficiency inherited recessively, it presents as a hemophilia-like bleeding disorder. It is treated with recombinant factor VIIa. Gene therapy approaches for treating FVII deficiency are promising Recombinant factor VIIa, marketed under the trade names AryoSeven and NovoSeven, is used for people with hemophilia who have developed antibodies against replacement coagulation factor, it has been used in the setting of uncontrollable hemorrhage, but its role in this setting is controversial with insufficient evidence to support its use outside of clinical trials. The first report of its use in hemorrhage was in an Israeli soldier with uncontrollable bleeding in 1999.
Risks of its use include an increase in arterial thrombosis. However, animal studies have not shown complications as seen in humans, in fact same of the studies show a better prognosis. In the military settings it is used as an off label intervention in complications related to disseminated intravascular coagulation related haemorrhage caused by penetrating trauma. Recombinant human factor VII while looking promising in intracerebral hemorrhage failed to show benefit following further study and this is no longer recommended. Factor VII has been shown to interact with tissue factor and protein kinase C.

Mission 31 was an undersea expedition organized by Fabien Cousteau. It was scheduled for November 2013, but was delayed to June 2014. On June 1, Cousteau and six crew members descended to the undersea laboratory Aquarius in the Florida Keys. Halfway through the expedition, three of crew were replaced. After 31 days and the crew ascended on July 2. Throughout Mission 31, Cousteau's team conducted extended scuba diving expeditions to collect scientific data and IMAX footage, they hosted various one-day guests, conversed live with classrooms, kept in touch with the outside world via social media. Cousteau estimated that his team collected the equivalent of two years' worth of surface dive data, enough for 10 scientific papers. Mission 31 was envisioned as a tribute to Cousteau's grandfather, Jacques Cousteau, who spent 30 days living underwater in 1963. Fabien Cousteau thus beat his grandfather's record for time spent underwater by a film crew by one day. In 1963, French oceanographer and filmmaker Jacques Cousteau spent 30 days living underwater in Conshelf Two, in the Red Sea.
The footage was turned into the Academy Award-winning film World Without Sun. Subsequently, his television show, The Undersea World of Jacques Cousteau, was seen by audiences around the world. Cousteau was one of the world's first advocates for governmental action in environmental protection and, by the time of his death in 1997, was one of the world's most famous television personalities. Jacques Cousteau's grandson, Fabien Cousteau, organized Mission 31 as a tribute to his late grandfather; the mission had two goals — to gather scientific data and to raise funds for Aquarius, an underwater laboratory located at a depth of 63 feet below the surface, about 9 miles south of Key Largo. Aquarius is the world's only operating undersea laboratory. Measuring 43 feet by 9 feet, it holds up to six people, it is pressurized, air conditioned, has wireless Internet access. A typical mission lasts 10 days, with the longest previous mission lasting 18 days. Aquarius is owned by the United States government's National Oceanic and Atmospheric Administration and run by Florida International University.
Fabien Cousteau hoped to break his grandfather's record for longest time spent underwater by a film crew, draw the public's attention to environmental issues. According to Guinness World Records, the longest time anyone has spent. Fabien Cousteau got the idea for Mission 31 when visiting Aquarius during a fundraiser aiming to keep the laboratory operating in the wake of federal budget cuts, it was scheduled to take place in November 2013, fifty years after Jacques Cousteau's original mission. When the United States federal government shutdown in October 2013, Fabien Cousteau elected to postpone the mission until the spring of 2014. On June 1, 2014, Cousteau and five team members dived down to Aquarius. Joining Cousteau for the entire 31-day expedition were habitat technicians Mark "Otter" Hulsbeck and Ryan LaPete; the other three crew members — Kip Evans, Andy Shantz, Adam Zenone — were replaced according to plan midway through the mission by Matt Ferraro, Liz Magee, Grace C. Young; the crew included researchers from Florida International University, Northeastern University, Massachusetts Institute of Technology.
For most of the crew, including Cousteau, it was their first saturation diving experience. Periodically, they were joined by "VIP guests" for a day, including Cousteau's father, Jean-Michel and sister Céline, actor Ian Somerhalder, marine biologist Sylvia Earle. Rapper will.i.am and businessman-explorer Richard Branson were tentatively scheduled to visit had the expedition taking place in October 2013 as planned. Days were spent diving to conduct experiments and gather data to study the effects of climate change and pollution on coral reefs, while the evenings were spent in Aquarius on lab work and stress tests: Cousteau and his crew made themselves available for physiological and psychological tests to determine the effects of long-term living under the sea and without sunlight; the crew appeared on Weather Channel broadcasts periodically. They used a sonar device that records a wide range of frequencies and a slow-motion camera to capture more thorough data and installed tiny probes, less than the width of a human hair, into the coral reef.
Among the animals seen during the expedition were eels, manta shrimp, plankton, snook, spotted eagle rays, starfish and various reef sharks. The crew observed an Atlantic goliath grouper attack a barracuda, a scene which Shantz described as "something I never imagined happening". Mission 31 was broadcast live 24 hours a day via the Internet, although the cameras were turned off to give the divers some privacy. Filming was done with sonar cameras to avoid disturbing the underwater life with artificial light. Team members were able to conduct live lectures for students and interact with the public through social media; the team ate "astronaut-type food", as the limited space did not allow for ordinary food. Early in the expedition, the air conditioning in Aquarius broke, leading to 95 °F temperatures at 95% humidity until it could be fixed; as they were undergoing 16 hours of decompression before resurfacing, the Mission 31 crew watched World Without Sun. Mission 31 cost an estimated US$1.8 million.
It was paid for through corporate sponsorship and private donations, including a crowdfunding campaign on Indiegogo. Swiss watchmaker Doxa sold a Mission-31 dive watch for $2,890, with 25% of the funds going to the expedition. Aquarius costs cost $15,000 a day to operate. By working out of Aquarius inste
