Artificial heart tested in humans

Artificial heart, created by Professor Alain Carpentier French, experience in patients three Parisian hospitals, reports Medical Xpress. Body is made of synthetic materials and biological tissues and should operate without interruption for five years. Cardiovascular surgeon Alain Carpentier (Alain Carpentier) is known as the creator of the most sought after heart valve. The result of his 15-year career was the artificial heart , created in conjunction with engineers at Astrium, a manufacturer of satellites. Artificial organ consists of 900 items. He has two divisions, separated by a partition from animal tissues. In the body embedded sensors that determine what kind of load at the moment a person experiences. This information is transmitted to a miniature computer, which, in turn, instructs the pump to pump blood faster or slower depending on the circumstances. Thus regulating blood pressure and blood oxygen level of the patient, depending on his level of activity. A separate...

Five Reasons You Should Get Vaccinated

From the dawn of time, the human population has periodically been decimated by outbreaks of serious disease. In the 1600s, bubonic plague was rife across Europe and millions perished from the disease. The influenza virus has also been a deadly killer over the centuries and even today, people still die from the more serious strains of the flu. But thankfully for mankind, many of the most serious diseases such as yellow fever, typhoid and diphtheria have been all but eradicated as a result of widespread vaccination programmes. Why Bother With Vaccinations?

Without protection from vaccinations, you and your family are at risk of serious disease or even death. Vaccinations Are Safe Millions of people are vaccinated every year and even though there a...

Effect of Childhood Vaccines, Immune System

Certain vaccines may not work as well in children who have been exposed to high levels of perfluorinated compounds (PFCs), a family of chemicals used to make everything from microwave popcorn bags and pizza boxes to carpets and nonstick cookware, new research suggests. In a study published this week in the Journal of the American Medical Association, researchers found that the higher the level of PFCs in a child's blood, the fewer antibodies the child produced after receiving vaccines for diphtheria and tetanus. In addition, kids with higher PFC exposure were more likely than their peers to have antibody levels too low to provide protection against those infectious diseases. "The immune system is more sluggish when these kids are vaccinated," says lead author Philippe Grandjean, MD, an adjunct professor of environmental health at the Harvard School of Public Health, in Boston. "It doesn't respond as well…and produces less antibodies." The number of ant...

The overlap of the cold and flu season with the holiday season can make it a challenge to stay healthy as you go to parties and get together with family and friends. Getting a flu shot is important, but other precautions can also reduce your risk of getting sick or of spreading illness to others, according to a Ryerson University news release. Here are some tips for a healthy holiday: When you have to cough or sneeze, do it in your sleeve or the inside of your sweater or jacket. That will prevent the spread of viruses to those nearby. Wash your hands regularly and always after using the restroom, before eating, and after blowing your nose. Use the air kiss or fake peck on the cheek instead of a kiss on the lips when greeting family and friends. Always use serving spoons or forks never your fingers to put food on your plate. If you're hosting a party, be sure to supply plenty of serving utensils and provide people with alternatives to reaching into bowls, such as making individual s...
