Researchers from Queen's University Belfast have discovered why antibiotics for treating people with cystic fibrosis are becoming less effective and how fat soluble vitamins might offer a viable solution.take vitamins today
A team of researchers led by Professor Miguel Valvano, from the Wellcome-Wolfson Institute for Experimental Medicine at Queen's University Belfast, has discovered why some particularly harmful bacteria are not responding to antibiotics.
The bacteria, Burkholderia cenocepacia, are highly antibiotic resistant and cause severe lung infections in people with cystic fibrosis.
This research study, recently published in the international journal mBio, unveiled that the administration of fat-soluble vitamins could increase the effectiveness of the antibiotics used to treat cystic fibrosis infections.
Lipocalins, the antibiotic-capturing proteins, latch on with more strength to fat-soluble vitamins than to the antibiotics. Therefore, fat-soluble vitamins such as vitamin E could help to improve antibiotic treatment by freeing the antibiotics from the lipocalins and allowing them to reach the target bacteria to fight the infection. Speaking about this breakthrough, Professor Valvano explains: "Antibiotic resistance is a global phenomenon which prevents the effective treatment of diseases. Our research shows that bacteria not only can resist the action of antibiotics once they are internalised but can also capture antibiotics before they reach and penetrate into the bacterial cells.
"This is an exciting and potentially life-changing finding, particularly relevant for cystic fibrosis patients who are chronically infected with multi-resistant bacteria. Armed with this knowledge, we can focus our efforts on finding alternative solutions to more effectively treat the infection in these patients.
"Fat-soluble vitamins can 'soak up' the lipocalins before they have a chance to bind the antibiotics, increasing the chances that antibiotics will reach the bacteria. "We are now exploring ways to reformulate antibiotics together with relevant vitamins for delivery into cystic fibrosis patients and assess their efficacy, so that patients can benefit from these findings."
Lung infections, mostly caused by bacteria, are a serious and chronic problem for people living with cystic fibrosis and are often treated with inhaled antibiotics. Over time, bacteria in the lungs can become resistant to antibiotics making it increasingly difficult to treat lung infections and leading to irreversible damage to the lungs.take vitamins today

Essential Minerals

Minerals: Functions and Sources The body needs many minerals; these are called essential minerals . Essential minerals are sometimes divided up into major minerals (macrominerals) and trace minerals (microminerals).  A balanced diet usually provides all of the essential minerals. The two tables below list minerals, what they do in the body (their functions), and their sources. Major minerals Mineral Function Sources Sodium Needed for proper fluid balance, nerve transmission, and muscle contraction Table salt, soy sauce; large amounts in processed foods; small amounts in milk, breads, vegetables, and unprocessed meats Chloride Needed for proper fluid balance, stomach acid Table salt, soy sauce; large amounts in processed foods; small amounts in milk, meats, breads, and vegetables Potassium Needed for proper fluid balance, nerve transmission, and muscle contraction Meats, milk, fresh fruits and vegetables, whole grains, legumes Calciu...

Vitamin C Can Reduce High Blood Pressure, Study Finds

Vitamin C Can Reduce High Blood Pressure, Study Finds CORVALLIS, Ore. - Researchers have discovered that a 500 milligram daily supplement of vitamin C can significantly reduce high blood pressure in hypertensive patients. The study, published this month in the medical journal Lancet, was done by scientists at the Boston University School of Medicine and the Linus Pauling Institute at Oregon State University. It was supported by the National Heart, Lung and Blood Institute of the National Institutes of Health. "Hypertension is a serious health problem in much of the world," said Balz Frei, professor and director of the Linus Pauling Institute, and a co-author of the research along with principal investigator Dr. Joseph Vita at Boston University. "It's a key risk factor in heart disease and strokes." "We believe this is a significant finding that may be of considerable value to patients who have moderately elevated blood pressure," Frei s...

Zinc can halt the growth of cancer cells, study says

Zinc can halt the growth of cancer cells, study says Zinc supplements can significantly inhibit the proliferation of esophageal cancer cells, according to a new study co-authored by a University of Texas at Arlington researcher. Previous studies had shown that zinc is essential for maintaining human health and protects the esophagus from cancer. However, it has never been fully understood why zinc has the ability to prevent cancer in the esophagus. In this study, a team led by Zui Pan, an associate professor of nursing at UTA's College of Nursing and Health Innovation and a noted esophageal cancer researcher, discovered that zinc selectively halts the growth of cancer cells but not normal esophageal epithelial cells. The finding was published this month in  The FASEB Journal , the official journal of the Federation of American Societies for Experimental Biology. Esophageal cancer is the sixth leading cause of human cancer deaths around the world, according to the Nation...
