Scientists develop method to track immune system enzyme in live animals

Scientists supported by the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) at the National Institutes of Health have created two mouse strains that will permit researchers to trace, in a live animal, the activity of an enzyme believed to play a crucial role both in the normal immune response as well as autoimmunity and B cell tumor development.

New computational system identifies viruses and bacteria

Now that the genome sequences of hundreds of bacteria and viruses are known, we can design tests that will rapidly detect the presence of these species based solely on their DNA.

Model of proline dehydrogenase created

Researchers at the University of Missouri-Columbia recently created a model of proline dehydrogenase, an important cancer-preventing enzyme in the human body, and analyzed how it works.

Single dose of vitamin D may be enough to boost the immune system to fight against tuberculosis

Their findings came from a study that identified an extraordinarily high incidence of vitamin D deficiency amongst those communities in London most at risk from the disease, which kills around two million people each year.

Simple equations track Listeria trails

Circles, slaloms, figure eights, and loop-the-loops , biologists studying the motion of Listeria monocytogenes sensed that these paths were related, but they didn't have a good way to define what fit in and what didn't.

Atypical pathogen treatment vital in hospitalized community-acquired pneumonia patients

Hospitalized patients with community-acquired pneumonia (CAP) who received treatment regimens against atypical disease-causing pathogens reached clinical stability quicker, had fewer days of hospitalization, and had lower mortality rates as a result of their disease, according to a large new study.

Engineered minichromosomes for medically useful proteins and metabolites

A team of scientists at the University of Missouri-Columbia has discovered a way to create engineered minichromosomes in maize and attach genes to those minichromosomes.

Researchers find a peptide that encourages HIV infection

UCLA AIDS Institute researchers have discovered that when a crucial portion of a peptide structure in monkeys that defends against viruses, bacteria and other foreign invaders is reversed, the peptide actually encourages infection with HIV.

Opossum DNA provides new insight into natural selection

Study of the DNA of a South American marsupial called the opossum has revealed that a gene's location influences whether or not it is likely to gather changes that could lead to disease.

When is food "done" enough to prevent food poisoning?

Food scientists have found that relying only on internal color to check if food is cooked properly isn't adequate. A beef patty may be brown throughout before it reaches 160 degrees Fahrenheit, the recommended minimum safe temperature. And a safely cooked hamburger may still appear pink on the inside.
