Virus Caught in the Act of Infecting a Cell

About the video: watch an animation showing the changes in the structure of a T7 virus as it infects an E. coli bacterium.

AUSTIN, Texas — The detailed changes in the structure of a virus as it infects an E. coli bacterium have been observed for the first time, report researchers from The University of Texas at Austin and The University of Texas Health Science Center at Houston (UT Health) Medical School this week in Science Express.

Multiple Sclerosis Study Reveals How Killer T Cells Learn to Recognize Nerve Fiber Insulators

Misguided killer T cells may be the missing link in sustained tissue damage in the brains and spines of people with multiple sclerosis, findings from the University of Washington reveal. Cytoxic T cells, also known as CD8+ T cells, are white blood cells that normally are in the body’s arsenal to fight disease.

Multiple sclerosis is characterized by inflamed lesions that damage the insulation surrounding nerve fibers and destroy the axons, electrical impulse conductors that look like long, branching projections. Affected nerves fail to transmit signals effectively. (more…)

Americans Have Worse Health than People in Other High-Income Countries

WASHINGTON — On average, Americans die sooner and experience higher rates of disease and injury than people in other high-income countries, says a new report from the National Research Council and Institute of Medicine.

The report finds that this health disadvantage exists at all ages from birth to age 75 and that even advantaged Americans—those who have health insurance, college educations, higher incomes and healthy behaviors—appear to be sicker than their peers in other rich nations. (more…)

Pesticides and Parkinson’s: UCLA Researchers Uncover Further Proof of a Link

Study suggests potential new target in fight against debilitating disease

For several years, neurologists at UCLA have been building a case that a link exists between pesticides and Parkinson’s disease. To date, paraquat, maneb and ziram — common chemicals sprayed in California’s Central Valley and elsewhere — have been tied to increases in the disease, not only among farmworkers but in individuals who simply lived or worked near fields and likely inhaled drifting particles.

Now, UCLA researchers have discovered a link between Parkinson’s and another pesticide, benomyl, whose toxicological effects still linger some 10 years after the chemical was banned by the U.S. Environmental Protection Agency. (more…)

Legal Options for Medical Malpractice Victims

As a patient, it is extremely important that you are aware of how a doctor, nurse, or any other medical professional is treating you at all times. Medical professionals are expected to adhere to the established standards of their profession when providing care, and if they do not, and you suffer harm as a result, you could take legal action. If a doctor, surgeon, or other practitioner acts in a negligent manner, either through an action he or she took or an action he or she failed to take, medical malpractice may have occurred and the victim may be able to pursue a lawsuit.

From failing to appropriately diagnose your condition to not providing you with the correct treatment in a timely manner, reckless actions from medical professionals can cause serious damage. Fortunately, victims may be able to secure compensation to help cover the costs associated with their unnecessary suffering. (more…)

Making Health Fun

Get Up and Do Something is source for optimal health

Mike Peterson believes that the best way to bring about changes in health behavior is to take an approach that’s fun, positive, and motivational.

So the website he developed and runs with the health promotion master’s students at the University of Delaware is “not about ‘guilting’ people into doing things — it’s about playing to their better angels.” (more…)

Targeted Micro-Bubbles Detect Artery Inflammation, MU Study Finds

Procedure done in pigs could potentially detect heart disease early in humans

COLUMBIA, Mo. — Heart disease is a leading cause of death throughout the world. Doctors say that it is important to detect heart disease early before it becomes too serious. Now, researchers at the University of Missouri have found a way that they believe could help detect heart disease before it progresses too far as well as identify patients who are at risk for strokes.

In a study published in Medicine and Science in Sports and Exercise, Isabelle Masseau, an assistant teaching professor in the MU College of Veterinary Medicine, found that she could use targeted micro-bubbles to detect artery inflammation in pigs. She says that this procedure may help detect patients with heart disease or who are at risk for strokes before those ailments become too serious by monitoring artery inflammation, as that is an early warning sign of health problems. She says this procedure may also help monitor the effectiveness of artery inflammation treatments. (more…)
