Law of physics can be demonstrated by collection of individual protein molecules

Experiments by biochemists at the University of California, Davis show for the first time that a law of physics, the ergodic theorem, can be demonstrated by a collection of individual protein molecules -- specifically, a protein that unwinds DNA. The work will be published online by the journal Nature on July 14.

White blood cells and the spread of cancer: an interview with Drs. Lorenzo Ferri and Jonathan Cools-Lartigue, McGill University

As surgeons who take care of cancer patients, we have observed a troubling association between patients who suffer from infections after surgery and the rapid spread of their cancer. We have reported this in lung cancer patients, and others have made these observations in a variety of different cancers. However, the mechanisms responsible for this association are still poorly understood.

Specific types of intestinal bacteria are major contributors to lymphoma

Researchers from UCLA's Jonsson Comprehensive Cancer Center (JCCC) have discovered that specific types of bacteria that live in the gut are major contributors to lymphoma, a cancer of the white blood cells that are part of the human immune system.

Cranberry consumption may prevent chronic infections

Consuming cranberry products has been anecdotally associated with prevention of urinary tract infections (UTIs) for over 100 years. But is this popular belief a myth, or scientific fact?

Researchers distinguish viral and bacterial infections in children with fever

In children with fever but no other symptoms of illness, it is difficult to know whether a child has a viral infection that will resolve on its own or a potentially serious bacterial infection that requires antibiotics.

Exalenz Bioscience launches BreathID Hp to test and treat H. pylori

Exalenz Bioscience, developer of advanced diagnostic systems that use a patient's breath to detect and help manage gastrointestinal and liver conditions, announced today the global launch of the BreathID Hp, a next generation device in the company's BreathID product line.

Infrared light allows characterization of pathogens

The bacterium Staphylococcus aureus (S. aureus) is commonly found in nature and frequently colonizes the skin and the upper respiratory tract of humans. A healthy immune system can fight the microorganism but once the immune system is weakened the pathogen can spread and lead to life-threatening diseases of the lungs, the heart and other organs.

Chickens purchased from farmers markets carry higher bacterial loads

Raw, whole chickens purchased from farmers markets throughout Pennsylvania contained significantly higher levels of bacteria that can cause foodborne illness compared to those purchased from grocery stores in the region, according to a small-scale study by researchers in Penn State's College of Agricultural Sciences

Study provides clear understanding of breast milk content and its effect on infants' health

Scientists are making strides toward unraveling the surprisingly complex chemistry underpinning that axiom of infant feeding "breast is best," according to an article in the current edition of Chemical & Engineering News.

Infant vaccination against pneumonia helps protect elderly

Children who receive a vaccine to prevent blood and ear infections, appear to be reducing the spread of pneumonia to the rest of the population, especially their grandparents and other older adults.

NPS MedicineWise calls on every Australian to fight against antibiotic resistance

In light of a paper released by the Office of the Chief Scientist today, NPS MedicineWise is calling on every Australian to do their part in the fight against antibiotic resistance in our community.

Scientists discover bacterium that stores biodegradable plastic

In Bolivia, in the largest continuous salt desert in the world, researchers from the Polytechnic University of Catalonia have found a bacterium that stores large amounts of PHB, a prized polymer. This biodegradable plastic is used by the food and pharmaceutical industries, for example to produce nanospheres to transport antibiotics.

Study reveals that contaminated ultrasound gel causes healthcare-associated infection

After a 2011 outbreak of P. aeruginosa, investigators at Beaumont Health System near Detroit, Michigan determined contaminated ultrasound gel was the source of bacteria causing the healthcare-associated infection.

Immune response to TB bacterium varies between patients of different ethnic origin

The immune response to the bacterium that causes tuberculosis (TB) varies between patients of different ethnic origin, raising important implications for the development of tests to diagnose and monitor treatment for the disease, according to new research published today in the journal PLOS Pathogens.

Collaborative research yields a wiring map on how TB responds to changes in environment

Despite decades of research on the bacterium that causes tuberculosis (TB), scientists have not had a comprehensive understanding of how the bacterium is wired to adapt to changing conditions in the host.

Book provides new insight on one of the most common infectious diseases, Chlamydia

Chlamydiae are obligate intracellular bacteria that cause one of the most common sexually transmitted infectious diseases in the world. The infection disproportionately impacts women and the highest prevalence of infection is found in adolescents.

Study identifies genomic regions associated with cholera susceptibility

An international research team has used a novel approach to identify genetic factors that appear to influence susceptibility to cholera. The findings by investigators from Massachusetts General Hospital (MGH), the Broad Institute and the International Center for Diarrh-al Disease Research, Bangladesh (ICDDR,B) indicate the importance of pathways involved in regulating water loss in intestinal cells and of the innate immune system in the body's response to the bacteria that causes cholera, which affects from 3 to 5 million people each year and causes more than 100,000 deaths.

Montreal researchers discover novel research model to study auto-immune diseases

A team of researchers at the IRCM, led by Dr. Javier M. Di Noia in the Immunity and Viral Infections research division, discovered a novel research model for the study of auto-immune diseases. The Montr-al scientists are the first to find a way to separate two important mechanisms that improve the quality of antibodies. This study was featured in a recent issue of The Journal of Immunology.
