Ribosomes spontaneously change their form during protein production

Ribosomes, the construction sites for proteins, are far more complex than previously assumed. During the production of proteins they constantly and spontaneously change their form. This performance of eukaryotic ribosomes has now been demonstrated for the first time by scientists at Charité - Universitätsmedizin Berlin, the Max-Planck-Institut für Molekulare Genetik in Berlin, and Cornell University in New York, with the aid of special electron microscopic and biophysical methods.

Novel genetic sequencing methods identify various bacteria on public restrooms

Everyone wonders what bugs might be lurking in public bathrooms. Now researchers are using novel genetic sequencing methods to answer this question, revealing a plethora of bacteria all around, from the doors and the floors to the faucet handles and toilet seats, with potential public health implications, as reported Nov. 23 in the online journal PLoS ONE.

Two-drug combination may alleviate radiation sickness in people

A combination of two drugs may alleviate radiation sickness in people who have been exposed to high levels of radiation, even when the therapy is given a day after the exposure occurred, according to a study led by scientists from Dana-Farber Cancer Institute and Children's Hospital Boston.

Cell-penetrating or antimicrobial peptides could treat atopic eczema

Scientists have found that a strain of yeast implicated in inflammatory skin conditions, including eczema, can be killed by certain peptides and could potentially provide a new treatment for these debilitating skin conditions.

Abnormal levels of caffeine in water indicate human contamination

Researchers led by Prof. S-bastien Sauv- of the University of Montreal's Department of Chemistry have discovered that traces of caffeine are a useful indicator of the contamination of our water by sewers.

Sore throat among young adults taking antibiotics for acne: Study

A new study reveals that young adults who take oral antibiotics for acne may be more likely to get sore throats. The reason behind this is unclear say researchers. However they add that long-term use of antibiotics might change the balance of bacteria in the throat. In principle, that could allow infection-causing strains to multiply.

New system could measure mechanical properties of living cells

Researchers are making progress in developing a system that measures the mechanical properties of living cells, a technology that could be used to diagnose human disease and better understand biological processes.

Titanium particles from artificial joints may play a direct role in painful inflammation

Many people with painful, creaky knees and hips find relief after replacing their bad joints with new artificial joints made from titanium. But some of these people develop painful inflammation that can lead to bone destruction and loosening of the new joint. A new study led by researchers at the University of Medicine and Dentistry of New Jersey and published by the Journal of Immunology suggests that tiny titanium particles that flake away from the artificial joints through normal wear and tear may play a direct role in that inflammation.

Scientists design math model that could guide future prostate cancer treatments

Scientists have designed a first draft of a mathematical model that someday could guide treatment decisions for advanced prostate cancer, in part by helping doctors predict how individual patients will respond to therapy based on the biology of their tumors.

Study identifies major risk factor for necrotizing enterocolitis

Many premature infants suffer a life-threatening destruction of intestinal tissue called necrotizing enterocolitis (NEC). Now a Loyola University Medical Center study has identified a major risk factor for NEC: Preemies with the AB blood type who develop NEC are nearly three times as likely to die from it as preemies with other blood types.

New insights into immune-system changes that may trigger cartilage breakdown

Challenging long-held notions that osteoarthritis is a result mainly of wear and tear on the joints, researchers led by Dr. William H. Robinson of the Department of Veterans Affairs Palo Alto Health Care System and Stanford University have provided new insights into the immune-system changes that may trigger cartilage breakdown.

Medical case report on a traumatic tiger attack on a child

Exotic animals—wild animals unsuited to domestication—are increasingly housed in domestic settings. This sometimes leads to traumatic attacks suffered by owners or visitors. An example of a tiger attack on a child is described in the November issue of the Journal of Neurosurgery: Pediatrics.

Novel antibacterial protein could prevent or treat E. coli O157:H7-induced food-borne infections

A novel antibacterial protein targeted against E. coli O157:H7 may offer a way to prevent or treat serious food-borne bacterial infections, as demonstrated in a study published in the December issue of Antimicrobial Agents and Chemotherapy.

Princeton acquires Tru-D SmartUVC Room Decontamination System to improve patient care

In early September, Princeton Community Hospital added the Tru-D SmartUVC™ Room Decontamination System to its arsenal of new technology that helps disinfect environmental surfaces in patient rooms and in operating room suites.

UVA develops new and faster method to track superbugs

University of Virginia Health System researchers are the first in the world to develop a new and faster method to track major infection-causing "superbugs" - a major key in preventing the spread of deadly infections.

Resistance of starved bacteria can be blocked

Many infections, even those caused by antibiotic-sensitive bacteria, resist treatment. This paradox has vexed physicians for decades, and makes some infections impossible to cure.

Potential new ways to design vaccines, antibiotics

A University of Louisville scientist has determined for the first time how the bacterium that causes Legionnaires' disease manipulates our cells to generate the amino acids it needs to grow and cause infection and inflammation in the lungs.

H2S plays a major role in protecting bacteria from effects of different antibiotics

Although scientists have known for centuries that many bacteria produce hydrogen sulfide (H2S) it was thought to be simply a toxic by-product of cellular activity. Now, researchers at NYU School of Medicine have discovered H2S in fact plays a major role in protecting bacteria from the effects of numerous different antibiotics.

TAU model discovers adaptable decision-making in bacteria communities

Much to humans' chagrin, bacteria have superior survival skills. Their decision-making processes and collective behaviors allow them to thrive and even spread efficiently in difficult environments.
