Biochemists determine atomic structure of new ABC transporter

Proteins belonging to the large and important family of ABC transporters have been associated with metabolic diseases and can cause resistance to antibiotics. Biochemists from the University of Zurich and the NCCR Structural Biology have succeeded in determining the atomic structure of a new ABC transporter. The insights gained could give rise to new therapies to treat multi-resistant bacteria, cystic fibrosis or gout, for instance.

Mere presence in a room can add 37 million bacteria

A person's mere presence in a room can add 37 million bacteria to the air every hour - material largely left behind by previous occupants and stirred up from the floor - according to new research by Yale University engineers.

Scientists uncover new layer of information in the genetic code

A hidden and never before recognized layer of information in the genetic code has been uncovered by a team of scientists at the University of California, San Francisco (UCSF) thanks to a technique developed at UCSF called ribosome profiling, which enables the measurement of gene activity inside living cells - including the speed with which proteins are made.

UofL researcher receives patent for novel biochemical discovery

University of Louisville researchers are a step closer to eliminating periodontal disease through their work to develop synthetic molecules that prevent a bacteria responsible for the disease from spreading throughout the mouth.

Researchers use game theory to understand dynamics of cancer tumor evolution under stress

In search of a different perspective on the physics of cancer, Princeton University and University of California, San Francisco researchers teamed up to use game theory to look for simplicity within the complexity of the dynamics of cooperator and cheater cells under metabolic stress conditions and high spatial heterogeneity. In the context of cancer, cooperator cells obey the general rules of communal survival, while cheater cells do not.

Gold nanoparticles used to introduce chemical residues into the immune system

Developing a drug or vaccine requires a delicate balancing act with the immune system. On one hand, medications need to escape detection by the immune system in order to perform their function. But vaccinations - de-activated versions of a disease or virus - need to do the reverse. They prompt the immune system to create protective antibodies.

Previously unknown mechanism helps intestinal bacteria to affect formation of blood vessels

Researchers at the Sahlgrenska Academy at the University of Gothenburg, Sweden, have discovered a previously unknown mechanism which helps intestinal bacteria to affect the formation of blood vessels. The results, which are presented in Nature, may provide future treatments of intestinal diseases and obesity.

New method uses E. coli bacteria to engineer human therapeutic glycoproteins

Escherichia coli - a bacteria considered the food safety bane of restaurateurs, grocers and consumers - is a friend. Cornell University biomolecular engineers have learned to use E. coli to produce sugar-modified proteins for making pharmaceuticals cheaper and faster.

IU biologist to genetically modify variants of chlamydia

An Indiana University biologist has been awarded over $2.3 million from the National Institutes of Health to genetically modify variants of the human pathogen chlamydia in hopes of finding a vaccine for the most commonly reported bacterial infectious disease in the United States.

Scientists create first full 3-D images of vitamin B12

In a paper published recently in the journal Nature, scientists from the University of Michigan Health System and the Massachusetts Institute of Technology report they have created the first full 3-D images of B12 and its partner molecules twisting and contorting as part of a crucial reaction called methyltransfer.

Ripeness of fruit determines how food-poisoning bacteria grow on them

The ripeness of fruit could determine how food-poisoning bacteria grow on them, according to scientists presenting their work at the Society for General Microbiology's Spring Conference in Dublin this week. Their work could lead to new strategies to improve food safety, bringing many health and economic benefits.

India’s TB treatment inadequate raising risk of drug resistance

India suffers from inadequate government-run tuberculosis (TB) treatment programs and a lack of regulation of the sale of drugs against TB. This has led to the rise in number of drug-resistant cases that are difficult to treat, health activists said Friday.

Commensal bacteria may play an important role in influencing and controlling allergic inflammation

When poet Walt Whitman wrote that we "contain multitudes," he was speaking metaphorically, but he was correct in the literal sense. Every human being carries over 100 trillion individual bacterial cells within the intestine -- ten times more cells than comprise the body itself.

Bacteriophages can tackle drug-resistant bacterial infections

Viruses that can target and destroy bacteria have the potential to be an effective strategy for tackling hard-to-treat bacterial infections. The development of such novel therapies is being accelerated in response to growing antibiotic resistance, says Dr David Harper at the Society for General Microbiology's Spring Conference in Dublin.

S. gordonii may trigger infective endocarditis

Oral bacteria that escape into the bloodstream are able to cause blood clots and trigger life-threatening endocarditis. Further research could lead to new drugs to tackle infective heart disease, say scientists presenting their work at the Society for General Microbiology's Spring Conference in Dublin this week.

New IVIG trial can reduce OCD symptoms in children with PANDAS

Criteria for a broadened syndrome of acute onset obsessive compulsive disorder (OCD) have been proposed by a National Institutes of Health scientist and her colleagues. The syndrome, Pediatric Acute-onset Neuropsychiatric Syndrome (PANS), includes children and teens that suddenly develop on-again/off-again OCD symptoms or abnormal eating behaviors, along with other psychiatric symptoms - without any known cause.

More supermarkets shun “pink slime”

Supermarket chains Kroger Co. and Stop & Shop announced Thursday that they would no longer sell beef that includes an additive with the unappetizing “pink slime.” Federal regulators say the ammonia-treated filler, known in the industry as “lean, finely textured beef,” meets food safety standards. But critics say the product could be unsafe and is an unappetizing example of industrialized food production.

Multiresistant bacteria withstand wastewater treatment processes

Large quantities of antibiotic-resistant bacteria enter the environment via municipal - and especially hospital - wastewater streams. Although wastewater treatment plants reduce the total number of bacteria, the most hazardous - multiresistant - strains appear to withstand or even to be promoted by treatment processes. This was demonstrated by Eawag researchers in a study carried out in Lake Geneva, near Lausanne.
