According to the information reported by the Associated Press, drug manufacturer Merck & Co. is currently financing campaigns to get states in the US to pass legislation that would make it compulsory for girls from the age of 11 or 12 to receive a new vaccine protecting against sexually transmitted human papillomavirus (HPV).

According to the Tuesday report of the Associated Press, healthcare providers would like a premature baby who was born earlier than any other surviving infant to stay in a Miami hospital for several more days.

Researchers have developed a new model of how the brain tells time, which challenges the commonly quoted theory of an internal clock generating and counting regular fixed moments.

The scientists from the University of California, Los Angeles, indicate that a sequence of physical alterations to the brain’s cells help it track the passage of time.

The first over-the-counter medication for the treatment of obesity in adult patients has been approved by the US Food and Drug Administration.

The medication, called alli (orlistat), is created to be used only along with a reduced-calorie, low-fat diet by overweight adult patients over the age of eighteen. According to the producer of the drug, GlaxoSmithKline, the medication helps people lose 50 per cent more weight than dieting alone.

Both children and adult patients use the same kinds of asthma medicines. The amount and kind of drug your child will require is dependent on the severity of the asthma. For mild intermittent cases, your healthcare professional can prescribe only a bronchodilator — a medication that helps breathing by relaxing the tight ring of muscle around the airways — for quick relief as soon as symptoms appear. More frequent or persistent cases will require the intake of daily medication in order to calm inflammation within the airways and to prevent further attacks.

The latest case studies published in Thursday’s New England Journal of Medicine emphasized the serious concerns about the abuse of alcohol-based hand sanitizers. The alcohol in these products is not the same as the type that can be found in drinks.

Coronary artery disease is the name that is frequently used to describe the buildup of fatty deposits and fibrous tissue (plaques) inside the arteries that are responsible for supplying blood to the heart (the coronary arteries). This buildup is known as atherosclerosis. Coronary atherosclerosis can finally cause the coronary arteries to become considerably narrower. This reduces the blood supply to parts of the heart muscle and activates a type of chest pain known as angina. Atherosclerosis may also lead to a blood clot to mold inside a narrowed coronary artery. This results in a heart attack, which can bring about considerable damage to the heart muscle.

Atherosclerosis is a condition connected with narrowing of the arteries. Due to this, the supply of blood to very important organs such as the heart, brain and intestines can be considerably reduced. In this disease the arteries are narrowed when fatty deposits known as plaques build up inside. Normally, plaques comprise cholesterol from low-density lipoproteins (LDL), smooth-muscle cells and fibrous tissue. Sometimes also calcium. Due to the fact that plaque grows along the lining of an artery, a rough area in the artery usual smooth surface is created. This rough area may lead to a blood clot in the interior of the artery, which can completely block the flow of blood. As a consequence, all the organs supplied by the blocked artery starve for blood and oxygen, and hence the cells may either die or become seriously damaged.

You should never expect that food labels will let you know whether the hamburger meat you are choosing comes from a cloned animal.

According to the report of The Associated Press, once the American government has approved of consumption of food coming from cloned animals (this approval is expected within the next year), the Food and Drug Administration (FDA) is not planning to require any special labeling. Generally, the calculation is that if the food appears to be safe to eat, its source doesn’t have to be recognized.

According to scientists, currently, a ground-breaking method of nerve re-growth makes it possible for a patient with a prosthetic arm to feel its movements.

The technique can considerably simplify the process of learning to use a new arm. Furthermore, combined with other innovations in prosthetic limbs, it could help arm amputees, especially injured soldiers coming back from Iraq and Afghanistan, improve the quality of their lives. "One of the greatest challenges with artificial limbs is how to tell a prosthesis what to do?" said the head of scientists, Dr Todd Kuiken, the director of the Neural Engineering Centre for Artificial Limbs at the Rehabilitation Institute of Chicago. "This paper describes one of our patients and demonstrates really amazing improvement in function. Our patients are seeing hundreds of per cent of improvement."
