Helen Murray Free
Helen Murray Free (February 20, 1923 – May 1, 2021) was an American chemist and educator. She is most known for revolutionizing many in vitro self-testing systems for diabetes and other diseases while working at Miles Laboratories. The tests are still marketed today with blood tests as Ascensia Diabetes Care, and urine tests under Siemens Healthineers. The pioneering dip-and-read strips, allowed for testing to be more convenient and efficient, enabling doctors and patients to be less reliable to laboratories for results. Early life and education Free was born in Pittsburgh, Pennsylvania, on February 20, 1923. Her father, James S. Murray, worked as a coal company salesman; her mother, Daisy Piper Murray, died during an influenza epidemic when Free was six. Free received her early education from the public schools in Youngstown, Ohio, and graduated in 1941 as the valedictorian of Poland Seminary High School. While attending a summer camp at the College of Wooster, she set her he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Indiana University South Bend
Indiana University South Bend (IU South Bend) is a public university in South Bend, Indiana. It is the third largest and northernmost campus of Indiana University. History Indiana University began offering classes in South Bend in 1922 as an extension of the main campus of Indiana University Bloomington. In the Great Depression, the superintendent of South Bend schools asked that more classes be added for those who could not afford to attend classes at the Bloomington campus. The classes were offered at Central High School in downtown South Bend and within a few years enrollment reached 500. Classes were taught by local high school teachers with master's degrees and occasionally by Bloomington faculty who traveled once a week for class. The university appointed a resident director in 1940. Lynton Keith Caldwell, then a graduate student at the University of Chicago, took on the job. In 1941, Ernest Gerkin was named the first permanent full-time faculty member. Donald Carmony ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clinistrip
Clinistrip, also known as CLINISTIX or the brand name Diastix, are specific clinical sticks for the detection of glucose. Clinistrip consists of a section that contains glucose oxidase that has been dried onto the paper pad. It is an example of a biosensor-based test for glucose. This is similar to the glucose oxidase assay, as the glucose in the urine, once the stick has been dipped into the urine, is oxidized to yield gluconic acid and hydrogen peroxide. The enzyme peroxidase is also present on the pad, and it utilizes the hydrogen peroxide produced to oxidise a dye A dye is a colored substance that chemically bonds to the substrate to which it is being applied. This distinguishes dyes from pigments which do not chemically bind to the material they color. Dye is generally applied in an aqueous solution and ... that results in a colour change. The intensity of the colour change on the pad reflects the amount of glucose present in the urine. Biochemistry methods Chemical t ...

Urine Test Strip
A urine test strip or dipstick is a basic diagnostic tool used to determine pathological changes in a patient's urine in standard urinalysis. A standard urine test strip may comprise up to 10 different chemical pads or reagents which react (change color) when immersed in, and then removed from, a urine sample. The test can often be read in as little as 60 to 120 seconds after dipping, although certain tests require longer. Routine testing of the urine with multiparameter strips is the first step in the diagnosis of a wide range of diseases. The analysis includes testing for the presence of proteins, glucose, ketones, haemoglobin, bilirubin, urobilinogen, acetone, nitrite and leucocytes as well as testing of pH and specific gravity or to test for infection by different pathogens. The test strips consist of a ribbon made of plastic or paper of about 5 millimetre wide, plastic strips have pads impregnated with chemicals that react with the compounds present in urine producing a char ...

Hepatitis A
Hepatitis A is an infectious disease of the liver caused by ''Hepatovirus A'' (HAV); it is a type of viral hepatitis. Many cases have few or no symptoms, especially in the young. The time between infection and symptoms, in those who develop them, is 2–6 weeks. When symptoms occur, they typically last 8 weeks and may include nausea, vomiting, diarrhea, jaundice, fever, and abdominal pain. Around 10–15% of people experience a recurrence of symptoms during the 6 months after the initial infection. Acute liver failure may rarely occur, with this being more common in the elderly. It is usually spread by eating food or drinking water contaminated with infected feces. Undercooked or raw shellfish are relatively common sources. It may also be spread through close contact with an infectious person. While children often do not have symptoms when infected, they are still able to infect others. After a single infection, a person is immune for the rest of his or her life. Diagnosis requir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
