Scientists chemically synthesize ECA-derived oligosaccharides relevant for immunotherapy

Immunotherapy using monoclonal antibodies is a promising treatment strategy, and it might now be within reach: American scientists have successfully prepared an oligosaccharide enterobacterial antigen for which a monoclonal antibody has been developed. The study is published in the journal Angewandte Chemie.

U.S. Navy leads government category in annual ranking of patent portfolios

Predicting the risk of pirate attacks on vital shipping lanes could soon be easier, thanks to a data system that's just one of 364 technologies patented by the U.S. Navy (DoN) in 2014.

Scientists produce functional liver cells from human embryonic and genetic engineered stem cells

The liver plays a critical role in human metabolism. As the gatekeeper of the digestive track, this massive organ is responsible for drug breakdown and is therefore the first to be injured due to overdose or misuse. Evaluating this drug-induced liver injury is a critical part of pharmaceutical drug discovery and must be carried out on human liver cells. Regretfully, human liver cells, called hepatocytes, are in scarce supply as they can only be isolated from donated organs.

Study shows why candidate vaccine used in HVTN 505 clinical trial not protective against HIV infection

A study by researchers at the National Institute of Allergy and Infectious Diseases and Duke University helps explain why the candidate vaccine used in the HVTN 505 clinical trial was not protective against HIV infection despite robustly inducing anti-HIV antibodies: the vaccine stimulated antibodies that recognized HIV as well as microbes commonly found in the intestinal tract, part of the body's microbiome.

IU scientists find evidence that invisible war between microorganisms may affect human health

Health experts have warned for years that the overuse of antibiotics is creating "superbugs" able to resist drugs treating infection.

Study shows link between liver-produced molecules, pneumonia susceptibility during sepsis

New evidence highlights the importance of the liver in immunity against bacterial pneumonia. The study is the first of its kind to directly show such a link between liver-produced molecules and pneumonia susceptibility during sepsis.

UIC, Northwestern University researchers create first artificial ribosome

Researchers at the University of Illinois at Chicago and Northwestern University have engineered a tethered ribosome that works nearly as well as the authentic cellular component, or organelle, that produces all the proteins and enzymes within the cell. The engineered ribosome may enable the production of new drugs and next-generation biomaterials and lead to a better understanding of how ribosomes function.

Discovery could put individuals with relapsing UTIs on fast track for new therapeutic regimen

It's one thing to grow bacteria in a test tube, perform a screen in the lab, and find a mutation in the pathogen's genes. It's a whole other thing, and much rarer, to find the exact same mutation in nature--in this case, in E. coli in urine samples from some 500 patients suffering from relapsing urinary tract infections.

Researchers uncover groundbreaking evidence for developing vaccine to prevent middle ear infections

Researchers from Griffith University's Institute for Glycomics, together with the Nationwide Children's Hospital in Ohio, have uncovered groundbreaking evidence to help vaccine developers prevent middle ear infections.

Consumption of B-GOS prebiotic has positive effect on gut microbiota, immune systems of elderly people

Clasado Biosciences Limited, the producers and suppliers of the second generation prebiotic Bimuno, a unique trans-galactooligosaccharide, and the Department of Food and Nutritional Sciences, The University of Reading, UK, today announce the results of human research demonstrating the positive effects of an advanced prebiotic on the immune system of the elderly.

Intestinal bacteria play crucial role in inducing anxiety, depression

Scientists from the Farncombe Family Digestive Health Research Institute at McMaster University have discovered that intestinal bacteria play an important role in inducing anxiety and depression.

Study provides new insights into mechanism that controls differences in gut's ability to fight infections

Considering how many microorganisms we ingest each day, our gut has an extensive and well-developed immune system. This defense is involved in acute and chronic gut diseases, but it varies dramatically among people. A persistent question is how our genetic make-up affects our gut's ability to fight infections. EPFL scientists have found that gut immunity is not affected by single genes but by entire groups of genes.

Wayne State leads landmark study that examines clinical use of polymyxin B to treat superbugs

With the decline of the development of new antibiotics due to the complexity and expense of discovering them, there has been a rapid growth of antibiotic resistant pathogens that is one of the leading causes of death. With the help of a nearly $4.9 million, 5-year grant from the National Institute for Allergy and Infectious Diseases of the National Institutes of Health, Wayne State University School of Medicine researchers are leading a landmark multi-center, international study that will provide essential information to clinicians for use of polymoxin B in critically ill patients where no other treatments will work.

Study finds strong link between diabetes and TB in tropical Australia

A 20-year study by James Cook University scientists has found a strong link between diabetes and tuberculosis in tropical Australia.

Hand washing tips to protect against many infections

As the beginning of the school year approaches, parents need to remind their children about the importance of hand washing. Every day people touch several surfaces including books, desks, door knobs, sink handles, and other people and many of them harbor germs like bacteria and viruses that can cause illnesses.

Twenty Radboud researchers receive Veni grant as part of Innovational Research Incentives Scheme

Twenty young and promising researchers from Nijmegen - eleven from Radboud University and nine from Radboudumc - are each to receive up to 250,000. NWO (The Netherlands Organisation for Scientific Research) is awarding the Veni grant as part of the Innovational Research Incentives Scheme.

Mowing of wetland plants in basins increases mosquito population, finds study

A study of the West Nile virus risk associated with "dry" water-detention basins in Central Illinois took an unexpected turn when land managers started mowing the basins.

New findings unlock clues to disease protection

When disease-resistant rice is invaded by disease-causing bacteria, a small protein produced by the bacteria betrays the invader. Upon recognizing that protein, the rice plants sense that a microbial attack is underway and are able to mount an immune response to fend off bacterial infection, reports a research team led by the University of California, Davis.

Researchers decode molecular mechanism of fish toxin that has potential to treat cancer

Pathogenic bacteria develop killer machines that work very specifically and highly efficiently. Scientists from the University of Freiburg have solved the molecular mechanism of a fish toxin that could be used in the future as a medication to treat cancer. The scientists have now published their research in the journal Nature Communications.
