Since the first appearance of the highly pathogenic avian influenza H5N1 virus in 1997, over 500 human cases have been reported--more than 60% of which resulted in death. Researchers are still trying to work out the many possible routes of disease transmission in order to decrease human exposure to the virus. This is not an easy task given how many wild and domestic birds may be carriers, and the variety of ways in which these animals may come into contact with both each other and the humans they can ultimately infect.
The development of simple tests to predict a leukemic relapse in young patients has come a step closer. Approximately 20 percent of young leukemia patients who are treated with stem cells derived from umbilical cord blood will experience leukemic relapse but new research findings published in Blood demonstrate that the blame falls partially on T cells, a subset of white blood cells.
The researchers analyzed blood samples from young children who received an umbilical cord blood transplant for the treatment of blood disorders, including leukemia. They were particularly interested in studying the three to six month time period post-transplantation, when the children were most susceptible to both relapse and infection.
If you're worried about getting the flu, chances are that you got an influenza vaccine; these are created on an annual basis and use a method from the 1950s; it is egg-based technology, literally produced in chicken eggs. Some vaccines, like polio, are now created using laboratory-grown cell lines that are capable of hosting a growing virus. The first is inefficient, the second is expensive.(1)
The future of vaccines looks a little different. The race is on to create a universal flu vaccine, one that does not have to be recreated each year, and to also bring the technology cost down to where it is more financially constructive to get people a vaccine than have them in the hospital.(2)
Well, according to a new study, blame the micro RNAs (miRNAs) linked to the X chromosome. The study, published in BioEssays, investigated the observation that women live longer than males and are more able to fight off shock episodes of sepsis, infection or trauma. Thus, the researchers from Ghent University, Belgium, decided to take a look at the X chromosome and the miRNAs linked to it.
Gonorrhea is a sexually transmitted disease (STD) that causes urethritis and pelvic inflammatory disease. Before AIDS, this was what you got for having promiscuous, unprotected sex with many anonymous partners in a consequence-free environment (a period known as "The 1970s" yet often assumed to be the '60s) and when you contracted it you took some antibiotics and then it was back to Studio 54.
Some people have no fingerprints. That might be handy in a burglary but it can be an issue when passing through immigration or in security situations where a fingerprint is required, like getting a notary public to take your five bucks for some benign document.
Like DNA, fingerprints are unique to each person or set of identical twins. That makes them a valuable identification tool for everything from crime detection to international travel. But what happens when the tips of our fingers are missing those distinctive patterns of ridges?
In many cases, you can determine a child's age by what affliction their helicopter parents have saddled them with and you don't even have to meet the kid. If they are ADHD, for example, they are likely close to graduating high school. If you look in a grade school today, 25 percent of kids will be on 'the spectrum' for Autism and those that aren't may have a life-threatening allergy.
A generation ago, very few children had allergies to nuts and so it was taken seriously. Today, with hyperactive parents flipping out in restaurants over nothing every day, there is a lot more skepticism. The result is that actual nut-allergy sufferers face hostility and disbelief when trying to find safe environments for their children.
Right now on the east coast of Australia where I live, we have an outbreak of the deadly Hendra Virus (HeV) which kills horses and humans and even infects dogs and I have to admit that I’m scared, especially as I own 3 horses and 3 dogs. Over the last month of July 2011, 14 horses have died and have potentially infected 55 people who are being tested for HeV and remain under observation along with any horses, dogs and cats that also came into contact with the sick horses. This is required even when that contact occurred before the infected horses started to exhibit any symptoms of the virus, as they were potentially infectious for at least 2 days beforehand while they were still outwardly symptom free.
Endocarditis is a dangerous and sometimes lethal infection of the heart sometimes caused after a dental procedure.
Henry VIII, King of England and founder of the Anglican Church, was basically the Brad Pitt of his day when he was younger. Charming, attractive and even kind, for a member of the Royal family. Yet he is most remembered for being gluttonous, impaired and executing wives.
