A nurse makes the decision on who will live
05-23-2007 · EurekAlert!Thymic nurse cells are specialized cells of the thymus capable of taking up as many as 50 developing T cells into their cytoplasm. In the June issue of Experimental Biology and Medicine, Dr. Guyden and his colleagues show that thymic nurse cells play a role in deciding which thymocytes that have been taken up will die, because they will become potentially harmful if they mature, and which will be released to continue the developmental process.

- Live kidney donors report high satisfaction rates and minimal health problems
11-28-2007 · EurekAlert!
Nine out of ten people who donated a kidney to a partner or family member would make the same decision again and would recommend the procedure to others. Researchers in Egypt, where live donations are the only legal option, also found that donor health was good and often better than the general population. The study was carried out between 2002 and 2007 on patients who had donated a kidney five to 30 years ago.

- How eating less might make you live longer
03-05-2007 · EurekAlert!
Caloric restriction in non-obese people translates into less oxidative damage in muscle cells, according to a new study by Anthony Civitarese, Eric Ravussin and colleagues (Pennington Biomedical Research Center). As oxidative damage has been linked to aging, this could explain how limiting calorie intake without malnutrition extends life span.

- Genes may make some people more motivated to eat, perhaps overeat
10-14-2007 · EurekAlert!
Science has found one likely contributor to the way that some folks eat to live and others live to eat. Researchers at the University at Buffalo, the State University of New York, have found that people with genetically lower dopamine, a neurotransmitter that helps make behaviors and substances more rewarding, find food to be more reinforcing than people without that genotype. In short, they are more motivated to eat and they eat more.

- Nanowaste needs attention of EPA, industry and investors
07-26-2007 · EurekAlert!
The Environmental Protection Agency must make key decisions about how to apply the two major end-of-life statutes to nanotechnology waste in order to ensure adequate oversight for these technologies, concludes a new report from the Wilson Center's Project on Emerging Nanotechnologies. However, the report notes that the agency lacks much of the data on human health and eco-toxicity that form the basis for such determinations, creating some tough challenges ahead in EPA's decision-making process.

- Molecules may help predict survival in liver cancer
01-30-2008 · EurekAlert!
Tiny molecules that help cells regulate which proteins they make might one day help doctors predict which liver-cancer patients are likely to live longer than others. Researchers compared levels of microRNA in tumor cells and adjacent nontumor cells from liver-cancer patients, most of whom also had hepatitis and cirrhosis. Patients with poor disease-free survival had low overall levels of 19 particular microRNAs compared with those showing better survival after 16 years of follow-up.

"We are the bouncers, the bodyguards, the 'shotgun' riders, the overseers, the maоtre d's, the stewards, the organizers, the managers and leaders for the patient ... Often we are the only thing between them and a sentinel event. See us, hear us, feel us." Welcome to the nurse's world, through the words of those who live there.
