Enough Events, or Not Enough? That Is Not the Question |
|
Tuesday, 06 May 2008 |
If you don't have a subscription to Cytometry Part A, it is highly recommend that you borrow a friend's or coworker's copy (or username and password) and check out the recent article by Mario Roederer, How many events are enough? Are you sure? (Cytometry Pt. A, Volume 73A, Issue 5, Pages 384-385 Published Online: 28 Feb 2008). In this communication to the editor Dr. Roederer lays out the rationale for looking at events not as "positive" or "real", but instead asking the question, "do the events represent what the researcher claims they are." Whether you are new to flow, or are a genuine flow master, Dr. Roederer's communication offers insight into what event numbers and percentages really mean in flow, and what types of questions researchers should ask in interpreting their data.

who say that this single event can set the stage for cancer's
migration to other parts of the body.

She is not responsible for the latest and greatest in anti-retroviral drug research, but Isabella Masemola's job is just as important: she ensures the condoms distributed in South Africa and the surrounding countries meet strict quality assurance standards. After a corruption scandal broke in 2007, where faulty condoms were allowed to pass assurance measures, Masemola became a senior testing officer for the South African Bureau of Standards, where she has tried to save face for the organization. In a region of the world where nearly 20 percent of the population has HIV/AIDS, her arrival and story couldn't be more timely. Read her fascinating story here .
