New bacterial strain could help in long-term cleanup of oil spills

Researchers have discovered a new strain of bacteria that can produce non-toxic, comparatively inexpensive "rhamnolipids," and effectively help degrade polycyclic aromatic hydrocarbons, or PAHs - environmental pollutants that are one of the most harmful aspects of oil spills.

TWI launches new educational module to understand role of biofilms in chronic wound infections

The Wound Institute today announced the launch of a new educational module "Exploring Biofilms," an accredited, online course designed to help practicing wound care specialists better understand the role that biofilms play in chronic wound infections.

Effective antimicrobial products can reduce hospital-acquired infections

The Centers for Disease Control estimate that more than two million people in the United States are affected annually by hospital-acquired infections. Meanwhile, a report released in April by the Agency for Healthcare Research and Quality concluded that this problem, which is worsening, requires urgent attention.

Anti-infectives could circumvent the problem of antibiotic resistance

For a successful infection, bacteria must outwit the immune system of the host. To this aim, they deliver so-called virulence factors through a transport channel located in the bacterial membrane.

Protein IL-10 removes Escherichia coli K1 bacterium from blood and reverses brain damage

A team of researchers at Childrens Hospital Los Angeles (CHLA), along with colleagues from the Keck School of Medicine of the University of Southern California and the Universite Auvergne, France, have discovered an important role for a small, naturally occurring protein called interleukin-10 (IL-10) in removing bacteria from the blood of infected mice and reversing damage to the brain.

Reprogrammed killer cells prevent metastasis

A team of researchers has developed a method to produce cells that kill tumour cells in the lab and prevent tumours forming in mouse models of cancer. Although the current work is in cells and mouse, if the research transfers to human biology, the new type of cell could be a new source for cell-based anticancer therapies.

Gamma interferon wakes-up sleeping stem cells to produce immune system cells to fight invading bacteria

Most of the time, the body's blood-forming (hematopoietic) stem cells remain dormant, with just a few producing blood cells and maintaining a balance among the different types.

Scientists develop plastic antibody that works in bloodstream of living animal

Scientists are reporting the first evidence that a plastic antibody - an artificial version of the proteins produced by the body's immune system to recognize and fight infections and foreign substances - works in the bloodstream of a living animal. The discovery, they suggest in a report in the Journal of the American Chemical Society, is an advance toward medical use of simple plastic particles custom tailored to fight an array of troublesome "antigens."

Baylor Institute of Immunology Research receives nearly $35M as grants in 2009

Even in an economy that's proved devastating to charitable giving and government grants, the Baylor Institute of Immunology Research (BIIR), a component of Baylor Research Institute (BRI), has managed to buck the trend: BIIR received grants totaling nearly $35 million in 2009.

Texas Tech signs worldwide license agreement for metallo-beta-lactamase inhibitors with RI Scientific

Officials at Texas Tech University System's Office of Technology Commercialization announced Wednesday (June 9) the signing of an exclusive worldwide license agreement for a chemical additive called an aptamer that makes certain existing antibiotics viable against antibiotic-resistant bacteria.

Inquiry into the hospital acquired killer bug starts

A Second World War veteran John Boyle died of Clostridium difficile infection after being admitted to hospital for the first time at the age of 90. He was diagnosed with the infection on January 25 this year and succumbed to it two weeks later. He was one of 18 patients to die at a Scottish hospital when the outbreak of this hospital-acquired infection was reported.

Scientists combine two agents to treat patients with multiple myeloma

Scientists from the Barbara Ann Karmanos Cancer Institute in Detroit presented data showing that by combining two treatment agents in the care of multiple myeloma patients, doctors can use higher dosages of chemotherapy before autologous stem cell transplant while alleviating painful and debilitating side effects like severe oral mucositis (mouth ulcers).

Researchers decipher how mast cells set immune defense on right track

In the event of an infection, the immune system releases messenger substances. These molecules can either activate immune cells to defeat invading pathogens, or inhibit them to prevent an excessive immune reaction. For this, the immune system has to decide very quickly what mixture of activating and inhibiting messenger molecules leads to a successful defence.

Research findings open door to development of new therapies for lymphomas, leukemias

Scripps Research Institute scientists have discovered a new way to target and destroy a type of cancerous cell. The findings may lead to the development of new therapies to treat lymphomas, leukemias, and related cancers.
