Research: Reducing antibiotics consumption does not necessarily reduce resistance

Antibiotic use-and misuse-is the main driver for selection of antibiotic resistant bacteria. This has led many countries to implement interventions designed to reduce overall antibiotic consumption. Now, using methicillin resistant Staphylococcus aureus (MRSA) as an example, Laura Temime of the Conservatoire National des Arts et Metiers, Paris, and collaborators warn that simply reducing antibiotics consumption does not necessarily reduce resistance.

Adaptimmune initiates Phase I/IIa open-label clinical trial in patients with ovarian cancer

Adaptimmune announced today that it has opened a Phase I/IIa, multiple-site, two-cohort, open-label clinical trial in ovarian cancer at Roswell Park Cancer Institute (RPCI) in Buffalo, N.Y., and City of Hope (COH) in Duarte, Calif.

New technology enables all of the world's crops to take nitrogen from the air

A major new technology has been developed by The University of Nottingham, which enables all of the world's crops to take nitrogen from the air rather than expensive and environmentally damaging fertilisers.

Researchers explain how gut bacteria can inactivate cardiac drugs

For decades, doctors have understood that microbes in the human gut can influence how certain drugs work in the body - by either activating or inactivating specific compounds, but questions have long remained about exactly how the process works.

Researchers uncover way to stop cancer cells using HIF-1 gene through synthetic biology approach

Scientists have discovered a new molecule that prevents cancer cells from responding and surviving when starved of oxygen and which could be developed into new treatments for the disease, according to new research published in the Journal of the American Chemical Society today (Friday).

Abbott's FreeStyle Precision Pro Blood Glucose and Beta-Ketone Monitoring System gets FDA clearance

Abbott today announced that it has received U.S. Food and Drug Administration clearance for its FreeStyle Precision Pro Blood Glucose and Beta-Ketone Monitoring System, an advanced blood glucose monitoring system designed to address the key needs of hospital customers: high accuracy, efficient operation, dual-band wireless access to immediate test results, and helps in the reduction of the risk of test strip cross-contamination.

FDA allows marketing of Xpert MTB/RIF Assay for treatment of TB

The U.S. Food and Drug Administration today allowed marketing of the Xpert MTB/RIF Assay, the first FDA-reviewed test that can simultaneously detect bacteria that cause tuberculosis and determine if the bacteria contain genetic markers that makes them resistant to rifampin, an important antibiotic for the treatment of TB.

Research findings provide insight into safety of central line uses outside hospital

Pediatric cancer patients whose central lines are used to treat them at home develop three times as many dangerous bloodstream infections from their devices than their hospitalized counterparts, according to the results of a new Johns Hopkins Children's Center study.

Forced-air patient warming systems may affect airflows in OR; increase exposure to airborne contaminants

Forced-air systems used to keep patients warm during surgery may affect the performance of operating room (OR) ventilation systems-potentially increasing exposure to airborne contaminants, reports a study in the August issue of Anesthesia & Analgesia, official journal of the International Anesthesia Research Society (IARS).

Discovery of pressure-driven infection mechanism opens door to new treatments for viral infections

The virus that causes those painful lip blisters known as cold sores has an internal pressure eight times higher than a car tire, and uses it to literally blast its infectious DNA into human cells, scientists are reporting in a new study.

Scientists develop simple, inexpensive and reliable method of detecting plague pathogen

Diagnosing the presence of Yersinia pestis, the cause of plague, may soon be easier than ever before. Scientists working with Peter Seeberger, Director at the Max Planck Institute of Colloids and Interfaces (MPIKG) in Potsdam and Professor at the Freie Universit-t Berlin, have come up with a simple, inexpensive and reliable method of detecting the bacterium.

Researchers discover mechanism that prevents immune system from spinning out of control

A team led by a University of Arizona researcher has discovered a previously unknown mechanism that prevents the immune system from going into overdrive, shedding light not only on how our body controls its response to pathogens but on conditions such as autoimmune diseases, allergies and chronic inflammation as well.

Bacterial crystal protein could be safe, inexpensive treatment for parasitic worms in humans

A benign crystal protein, produced naturally by bacteria and used as an organic pesticide, could be a safe, inexpensive treatment for parasitic worms in humans and provide effective relief to over a billion people around the world.

Discovery may help explain how anti-inflammatory steroid drugs work

A gene long presumed dead comes to life under the full moon of inflammation, Stanford University School of Medicine scientists have found.

FDA revokes policy that prohibited sale of feed contaminated with Salmonella

On Tuesday, the U.S. Food and Drug Administration formally revoked a 1967 policy that prohibited the sale of feed contaminated with Salmonella. As a result of this policy change the agency will allow feed known to be contaminated with Salmonella to be fed to pigs, chickens and cattle.

Study reveals that Hudson River polluted with antibiotic-resistant bacteria

The risk of catching some nasty germ in the Hudson River just started looking nastier. Disease-causing microbes have long been found swimming there, but now researchers have documented antibiotic-resistant strains in specific spots, from the Tappan Zee Bridge to lower Manhattan.

Scientists find that lipocalin 2 protein disables macrophages in bacterial pneumonia

Macrophages, also known as scavenger cells, play an important role in defending against bacteria and pathogens by activating inflammatory processes. In cases of lung inflammation (pneumonia) caused by pneumococcal bacteria, this important immune response function is hampered and blocked by the protein lipocalin 2.

Structural properties have changed across bacterial families without putting limits on antibiotic resistance

Antibiotic-resistant bacteria have been emerging at an alarming rate. In some of the scariest of these pathogens, the mechanism responsible for the bacteria's ability to defeat antibiotics is a complex protein molecule embedded in the bacterial cell wall -- the enzyme β-lactamase.

Researchers visualize live cell-to-cell communication pathways in bacteria

Most bacteria are able to communicate with each other by secreting signaling molecules. Once the concentration of signals has reached a critical density (-the Quorum), the bacteria are able to coordinate their behavior
