A new way that could lead to dramatic reductions in human cholesterol levels has been discovered by Brandeis University scientist.

Senior Brandeis research scientist Daniel Perlman was issued a U.S. patent (number 8,460,738) on the new process.
Phytosterols in plants and cholesterol molecules in animals are highly similar and when both are dispersed together they are attracted to one another.

When they mix in the gut of an animal, the cholesterol molecules are competitively inhibited from passing into the blood stream and instead are excreted.


Purified components of ginger may have properties that help asthma patients breathe more easily, a study from researchers at Columbia University have revealed.

Asthma is characterised by bronchoconstriction, a tightening of the bronchial tubes that carry air into and out of the lungs. Bronchodilating medications called beta-agonists are among the most common types of asthma medications and work by relaxing the airway smooth muscle (ASM) tissues.

This study looked at whether specific components of ginger could help enhance the relaxing effects of bronchodilators. The researchers say they plan to study whether an aerosol spray to deliver these ginger compounds might be helpful in treating asthma attacks.


What is ischemia?
Ischemia is a condition in which the blood flow (and thus oxygen) is restricted or reduced in a part of the body. Cardiac ischemia is the name for decreased blood flow and oxygen to the heart muscle.
What is ischemic heart disease?
It’s the term given to heart problems caused by narrowed heart arteries. When arteries are narrowed, less blood and oxygen reaches the heart muscle. This is also called coronary artery disease and coronary heart disease. This can ultimately lead to heart attack.

Ischemia often causes chest pain or discomfort known as angina pectoris.

What is silent ischemia?
Many people may have ischemic episodes without knowing it. These people have ischemia without pain — silent ischemia. They may have a heart attack with no prior warning. People with angina also may have undiagnosed episodes of silent ischemia. In addition, people who have had previous heart attacks or those with diabetes are especially at risk for developing silent ischemia.


Many people rarely think about the possibility of having a stroke, believing that stroke happens only to old people, to people who are sick with other major diseases, or mostly to men.

The reality is much different. According to the National Stroke Association, stroke is the fourth-leading cause of death in the United States, affecting people of all ages and races, both men and women. In fact, 55,000 more women than men have a stroke each year, and women are twice as likely to die from stroke than from breast cancer in any given year.

This are the key elements of identifying and responding to a stroke:

F—Face drooping. Does one side of the face droop, or does the person say it feels numb? Ask the person to smile to help you determine whether or not the face is drooping.

A—Arm weakness. Ask the person to raise his or her arms. Watch to see if one arm drifts back downward, as if the person is having trouble controlling it.

S—Speech difficulty. Is the person having trouble speaking, or is it difficult to understand what he or she is saying? Ask the person to repeat a simple sentence, such as “The sky is blue,” and see if he or she is able to do so.
