People who repeatedly recover from ordinary seasonal flu or a few times vaccinated, perhaps, to some extent are protected from the swine flu A virus H1N1, researchers from the United States reported.
They found evidence that the human immune system can partially recognize A virus H1N1 virus, which is something still similar to seasonal influenza viruses.
“Swine influenza is a bit like an ordinary flu, which may suggest that humans already have a partial immunity against it. Perhaps this can make the disease less severe among the general population than previously estimated,” – said Alessandro Sette, Ph.D. Head and Member Center for Infectious Disease in California.
The study also may help explain why many older people are not so hard to carry the disease, said Ellison Dekhat Augustine from the National Institute of Allergy and Infectious Diseases. “We adults may be a partial immunity against A virus H1N1,” – she said.
Swine flu has swept through about 22 million Americans from April to October, killing an estimated 3,900 people, including 540 children.
“We’ve been tracking influenza for decades,” says Anne Schuchat, director of the CDC’s National Center for Immunization and Respiratory Diseases. “What we are seeing in 2009 is unprecedented.”

The main and most important mechanism of massage action is revitalization of the nervous system. And through the nerve endings massage impacts on all organs and tissues. Masseur must know massage techniques that can increase or decrease the excitability of the nervous system depending on the initial state of the human body.
During the massage is also accelerating the metabolic processes and stimulation of blood and lymph vessels, which promotes the excretion of metabolic products and excess fluid to relieve venous congestion. Under the action of massage is growing network of small blood vessels, and thus improves blood supply to the skin, subcutaneous tissue, muscle tissue and internal organs.
The variety of species and methods of massage
First of all, massage is divided into therapeutic and hygienic.
Therapeutic massage is appointed to the sick people in order to restore their health and hygienic massage is for prevention objectives for healthy people.

Study Group of the Wake Forest University have successfully grown a rabbit’s penis, based on collagen and cells of rabbits. With artificial penis rabbits regained not only erectile function but also the reproduction ability, a medical conference in the U.S. has been told.
The research was led by the team of Dr. Anthony Atala, who said that the novel experiments raise hope that tissue engineering can one day be used to help men with severe impotence, or needing penile reconstruction, to regain their full sexual function.
The concept is that cells from a reduced organ are sprayed onto a collagen matrix, then bathed with compounds that stimulate cell growth and left in kept in an environment that duplicates the temperature and chemical makeup of living tissue.

Why do we need contact lenses? Most people prefer them instead of glasses, which, in their view, distort the appearance. In addition, there are many other benefits for contact lenses wearers:
- vision becomes more natural, the size of objects close to the real;
- the contact lens moves with the eye, so there is no distortion inherent in the use of glasses;
- the field of view is not limited as by spectacles;
- contact lenses never mist.

The brown recluse spider exists in significant populations mainly in the central Midwestern states southward to the Gulf of Mexico, especially in Oklahoma, Arkansas and Missouri.
SIZE
Body – 1/4 to 1 inch. The legs span an area roughly the size of a quarter to a half-dollar.
COLOR
Light brown to a dark, reddish or chocolate brown, but most are light to medium brown.
HABITAT
Houses are the common habitat of this kind of spider. Inside homes, the brown recluse spider can be found in any of the following places: dark spots within baths, dormitories, garages, closets and cellars, vent and heating conducts, seldom used clothes or shoes. They can nest in stored clothes, old books, boxes, furniture, toys, carpets, coatings, corners and cracks.
POISON
The spider has a powerful poison and occasionally bites a person, thus causing local injuries and sometimes more common symptoms. The poison causes the necrosis of the soft tissue that starts as a local inflammation with reddening, edemas and pain.

New research being presented at an obesity conference this week found that the cereals that are most frequently and aggressively marketed directly to American children as young as 2 were also the least healthy.
The study, reported in The Cereal Food Advertising to Children and Teens Score Report, was part funded by the Robert Wood Johnson Foundation, and was conducted by researchers from Yale University’s Rudd Center for Food Policy and Obesity. It is being presented at Obesity 2009, the 27th annual scientific meeting of The Obesity Society, in Washington on 27 October.
Researchers find that cereals for children have 85% more sugar, 65% less fiber and 60% more sodium than cereals marketed to adults. In addition, companies are spending more than $156 million a year to market these cereals directly to kids.

Many of colored contact lenses are available with and without vision correction so even people without a need for vision correction can wear them, as well as people who have astigmatism, or need bifocal contact lenses. The center of the lens, the part that lies over your pupil, is clear so you can see.
An enhancement tint is a solid but translucent (see-through) tint. An enhancement tint changes your eye color. As the name implies, it’s meant to enhance the existing color of your eyes. These types of tints are usually best for people who have light colored eyes and want to make their eye color more intense. Color tints are deeper, opaque tints that can change your eye color completely. Usually they are made of patterns of solid colors. If you have dark eyes, you’ll need this type of color contact lens to change your eye color. Color contacts come in a wide variety of colors, including green, amethyst, blue, gray, violet, and hazel.

A new study found that many contact lens wearers in the United States do not follow the recommended replacement schedules for their lenses, making them vulnerable to a variety of eye infections, which cause serious eye problems.
The study examined 1,654 contact lens wearers in groups with different replacement frequency. It found that people wore their contact lenses for a much longer period of time than recommended and didn’t replace contact lens case in time:
- 26 % of those who over-wore their lenses said they wanted “to save money” by wearing their contacts for longer periods
- 51 % said they “forgot which day to replace their contact lenses”
- 18 % of participants reported it was “not important” to clean contact lenses every day
- 16 % of contact lenses wearers replaced their contact lens case only once a year
- 14 % never replaced their lens case

What is a blood test?
Blood tests are a very useful diagnostic tool. Blood is made up of several different kinds of cells and other compounds, including various salts and certain proteins. When blood clots outside the body, the blood cells and some of the proteins become solid. The remaining liquid is called serum, which can be used in chemical tests and in tests to find out how the immune system fights diseases.
What do doctors examine in the blood?
Blood contains two main elements: the fluid that is called plasma and cells. There are three kinds of cells: red blood cells, white blood cells and platelets. To get the information they need from the blood, doctors actually do several tests with the blood sample. These include measurements of the levels of the cells and a blood smear. A blood smear is a film of blood placed on a slide to allow doctors to look at the individual cells under a microscope.

C-reactive protein (CRP) is a protein produced by the liver when there is inflammation somewhere in the body. People with high levels of CRP may be at higher risk for an acute coronary event (heart attack) and death but not stroke, according to a study published in the October 20, 2009, print issue of Neurology®, the medical journal of the American Academy of Neurology.
According to the scientists, testing for this protein – which is released into the bloodstream when the blood vessels leading to the heart are damaged – adds to the predictive value of screening blood samples for both total and HDL (good) cholesterol levels. Thus C-reactive protein testing may improve doctors’ ability to predict heart disease risk.
