Scientists develop measures to prevent health problems associated with biogenic amines in wine

Biogenic amines may be one of the factors responsible for symptoms such as headaches, gastro-intestinal disorders, shortness of breath, fall in blood pressure, and even unconsciousness and cardiac arrhythmia in severe cases. Histamine, one of the best known members of this group, can cause serious physical problems. Biogenic amines can be produced in the body by natural metabolic activities but are also ingested in larger quantities with food.

Alpha-herpesvirus axon-to-cell spread involves limited virion transmission

New research suggests that just one or two individual herpes virus particles attack a skin cell in the first stage of an outbreak, resulting in a bottleneck in which the infection may be vulnerable to medical treatment.

Loyola announces 2012 Junior and Senior Scientist of the Year during St. Albert's Day

Katherine L. Knight, PhD, one of the nation's leading immune system researchers, has been named 2012 Senior Scientist of the Year at Loyola University Chicago Stritch School of Medicine. Sakthivel Sadayappan, PhD, FAHA, who is doing groundbreaking research on a protein that is critical for the normal functioning of the heart, has been named 2012 Junior Scientist of the Year.

Researchers show how bacteria control processes in human cells

Bacteria can talk to each other via molecules they themselves produce. The phenomenon is called quorum sensing, and is important when an infection propagates. Now, researchers at Link-ping University in Sweden are showing how bacteria control processes in human cells the same way.

University of Alberta medical research supports the 'obesity paradox'

Medical researchers at the University of Alberta studied the records of nearly 1000 patients who were admitted to hospital with pneumonia and noted those who were obese were more apt to survive compared to those who were of normal weight.

Weill Cornell researchers awarded Grand Challenges Explorations grants

Weill Cornell Medical College announced today that it is a Grand Challenges Explorations winner, an initiative funded by the Bill & Melinda Gates Foundation.

Mass spectrometry can help visualize how drugs work inside living cells to kill infectious microbes

Weill Cornell Medical College researchers report that mass spectrometry, a tool currently used to detect and measure proteins and lipids, can also now allow biologists to "see" for the first time exactly how drugs work inside living cells to kill infectious microbes.

Microbiologists confirm existence of new tick disease in Switzerland

Until now, we knew that ticks primarily transmit two pathogens to humans in Switzerland: the bacterium Borrelia burgdorferi - which causes borreliosis - and the early-summer-meningoencephalitis virus, which can cause cerebral inflammation. Now, microbiologists from the University of Zurich confirm the existence of another tick disease in Switzerland - neoehrlichiosis.

Research team receives grant to study impact of urban air pollution on TB immunity

An international team of researchers, led by Stephan Schwander, MD, PhD, director of the Center for Global Public Health at the University of Medicine and Dentistry of New Jersey-School of Public Health, has received a $2.96 million grant to conduct a "real-world" study on the impact of urban air pollution on the human immune system's ability to resist Mycobacterium tuberculosis, the bacterium that causes tuberculosis.

Allergies and hygiene: an interview with Sally Bloomfield

Allergies occur when the body overreacts to substances in our environment, such as pollen, dust mites and so forth. What happens is that when we are exposed to these potential threats, the immune system should react, deal with it, and then shut down.

CUMC researchers develop first true mouse model of typhoid infection

Columbia University Medical Center (CUMC) researchers have created the first true mouse model of typhoid infection. The development promises to advance the study of typhoid and the creation of new vaccines against the infection, which remains a major health threat in developing countries.

New study finds bacteria cue single-celled choanoflagellates to form colonies

Bacteria have a bad rap as agents of disease, but scientists are increasingly discovering their many benefits, such as maintaining a healthy gut.

UNM Cancer Center scientist to continue histone modification study

While every one of our cells contains all of our genetic information, each type of cell uses only specific parts of that information to make its proteins. Uncovering more about the mechanism that directs which particular pieces of genetic information the cell uses is the research focus of Mary Ann Osley, PhD, University of New Mexico Professor of Molecular Genetics and Microbiology and Co-Leader of the Cancer Biology and Biotechnology Program at the UNM Cancer Center.

BioResearch Open Access explores Cell-SELEX technology

SELEX is a rapid, efficient, and iterative high-throughput method for screening large libraries of molecules to identify those with the potential to be developed as drug compounds or research tools. Advances in SELEX technology that have enabled screening in live cells, called Cell-SELEX, are explored in a comprehensive Review article published in BioResearch Open Access, a bimonthly peer-reviewed open access journal from Mary Ann Liebert, Inc.

Study determines how Trop2 protein drives growth of tumor cells in prostate and other epithelial cancers

Researchers led by Tanya Stoyanova and Dr. Owen Witte of UCLA's Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research have determined how a protein known as Trop2 drives the growth of tumor cells in prostate and other epithelial cancers.

Maryland scientists create stem cell model for Gaucher disease

A new method of using adult stem cells as a model for the hereditary condition Gaucher disease could help accelerate the discovery of new, more effective therapies for this and other conditions such as Parkinson's, according to new research from the University of Maryland School of Medicine.

Researchers develop two ultra-rapid tests for diagnosis of antibiotic resistance

With their excellent sensitivity and specificity, the use of these extremely efficient tests on a world-wide scale would allow us to adapt antibiotic treatments to the individual's needs and to be more successful in controlling antibiotic resistance, particularly in hospitals.
