List of famous alumni from Duke University, with photos when available. Prominent graduates from Duke University include celebrities, politicians, business people, athletes and more. This list of distinguished Duke University alumni is loosely ordered by relevance, so the most recognizable celebrities who attended Duke University are at the top of the list. This directory is not just composed of graduates of this school, as some of the famous people on this list didn't necessarily earn a degree from Duke University.
Red blood cells ferry oxygen to tissues, providing fuel for muscular activity. Unscrupulous athletes have been able to 'dope' their blood by enriching their supply of red blood cells. While tests have been developed to detect two of the three most common methods of dramatically boosting the oxygen-carrying capacity of a competitor's blood, so-called "autologous" or self-transfusions have been impossible to detect.
An autologous transfusion takes some of the athlete's blood out well before the competition, sorts out just the red blood cells, and then transfuses those cells back into the athlete right before competition to enhance the blood's ability to carry oxygen, the essential fuel of muscle performance.
The best detection method the World Anti-Doping Agency WADA has used to date is the "Athlete Passport," which compares a pre-competition blood sample to one taken at competition to see if there are 'significant' changes in biochemistry. Blood banks in the U.
The amount of energy-providing ATP drops and oxygen-binding hemoglobin declines as well. But those changes have not been precise enough to detect an autologous transfusion.
What Chi and his colleagues looked at in the red blood cells is nucleic acids, specifically RNA. Red blood cells were long thought to lack nucleic acids because they don't carry a nucleus, where one would normally find DNA.
But it turns out they contain an abundant and diverse population of RNAs. The researchers drew three units of blood from volunteers and processed them to remove virtually all of the white blood cells and about 80 percent of the plasma, leaving behind a relatively purified sample of red blood cells, just as an autologous transfusion would require.
Then Jennifer Doss, a former Duke graduate student, and other lab members extracted and analyzed RNA samples taken from the cells at eight time intervals, from 1 day to 42 days.
Changes in the RNA associated with storage became apparent as they compared the later samples to the Day 1 sample. Two types of miRNA increased in number during storage and two declined, said graduate student Wen-Hsuan Yang, who performed the biochemistry experiments.
One of the forms that declined, called miR, had the most dramatic and consistent changes. With further testing, the researchers isolated the likely source of this nucleotide fragment of RNA.
It seems to result as a byproduct from a larger RNA that is cut by enzymes during storage, and it happens in a very precise, predictable way.
He said further research is focused on understanding why the enzyme that produces miR is active in stored cells and what it might be doing as it breaks a larger RNA apart. This research, which appears Oct.
British Journal of Haemotology, Oct.4 ABSTRACT This thesis examines the academic and athletic priorities of collegiate student-athletes, using Duke University as a case study. Analyses of information. Duke University is a mesmerizing, intimidating place for a small town Midwestern girl, so I had few goals beyond passing classes for my future at the university when I arrived on campus in We work closely with Duke students and alumni who aspire to careers in the health professions.
Our guidance and advice can help you tailor your undergraduate academics to best meet the qualifications of medical schools, dental schools, veterinary schools, and more. Duke in New York and Duke in LA programs. Some are athletes. Some . Thesis Guidelines A thesis for Distinction in Biology should be a presentation, written primarily for the non-specialist reader, of the significance, results and conclusions of a productive research project.
DURHAM, N.C. -- A Duke University research team has found a way to help sporting officials detect whether an athlete's blood has been doped by an infusion of their own stored blood. While tests.
