...ndividuals whose immune system is compromised (for example individuals with HIV and individuals who are taking chemotherapeutics to treat cancer). It can cause either cryptococcal pneumonia or, more seriously, meningoencephalitis. In a study that appears online on February 8 in advance of publication in the ...

Prehistoric origins of stomach ulcers uncovered

...controversial questions about human migration. For example we could use our understanding of the bacteria's spread to gauge poorly understood human population shifts in Europe, Africa and Asia." ...

Sea creature's toxin could lead to promising cancer treatment

...ake cancer chemotherapy so difficult. It's a great example of how NIH support for fundamental chemical research can benefit the American health-care consumer." The animal, Diazona angulata , is a sea squirt a few inches wide that lives in colonies anchored to rocks. It was discovered offshore of the Phili...

Bioengineering efficient antibiotic biosynthesis in E. coli

...ient precursor-directed biosynthesis. As the first example of bioassay-guided evolution of an antibiotic pathway in E. coli, these results open the door for harnessing the power of genetics for mechanistic investigations into polyketide synthases and also for biosynthetic engineering....

Human skin harbors completely unknown bacteria

...ial species, however, the insides of the body, for example the stomach, and the exterior of the body, the skin, show vast differences in bacterial populations. Skin condition can change markedly due to a variety of factors such as climate, diet, personal hygiene, and disease. But skin is never devoid of...

Climate change only one symptom of a stressed planet Earth

...isciplinary approach to climate change, is a clear example of how the Earth needs to be considered as a coupled system in order to understand global environmental change," says Noone. "The study of the Earth as a system, looking not only at climate but also at changes in the oceans and on land, how those cha...

Lipid plays big role in embryonic development

...iolet radiation, says Mr. Krishnamurthy, is a good example of what may increase ceramide levels. To study the quantity and location of ceramide, the researchers first developed an antibody that binds to it so it could be seen and counted. Previously, chemical studies have documented its presence but nothin...

Extreme irritability -- is it childhood bipolar disorder?

2 brains -- 1 thought

...minimal. "Applied to a real network, one could for example analyse which structural optimisation principles function in evolution," says Timme. The dynamics of a number of very simple networks that generate repetitive patterns - like the insect walking pattern - are already well-understood. Has evolutionary ...

Endangered shortnose sturgeon saved in Hudson River

... evidence for a large and secure population are an example of successful protected species management," said Bain. "Scientists and legislators have called for changes in the U.S. Endangered Species Act; the act is being debated in Congress and has been characterized as failing to recover species." However, h...

Virginia Tech's System X supercomputer provides super tool for simulation of cell division

...tion of what is going on inside the cell. A simple example is the conversion between Fahrenheit and Celsius temperatures, said mathematician Layne Watson. "You could use several pairs of Fahrenheit and Celsius readings for the same temperature, and try to deduce the formula for converting between the tempera...

Marshfield Clinic's electronic health record first to receive CCHIT certification

..."Our pursuit of CCHIT Certified status is one more example of Marshfield Clinic's commitment to remain a national leader in using information technology to improve patient care," said Justin Starren, M.D., Ph.D., FACMI, director, Marshfield Clinic Biomedical Informatics Research Center and associate medical ...

Study provides first genetic evidence of long-lived African presence within Britain

Whilst they are very likely to predict the correct ethnicity by using wider analysis of DNA other than the Y chromosome, finding this remarkable African chromosome would certainly have them scratchin...

U of MN adult stem cell research shows promise for transplant therapies

...can make blood when transplanted, this is a second example demonstrating that MAPCs can contribute to a tissue when grafted in vivo."This work provides the first evidence that human MAPCs can be induced to differentiate into the different types of cells needed to form arteries," Prosper said. "This may sugg...

Producing medicines in plant seeds

...re actually needed. With production in leaves, for example - or with conventional production methods - such lengthy storage is not possible: the protein must be isolated immediately after production. So, production in plant seeds provides the clear advantage of timely processing. High production of an eff...

Putting a face on the earliest modern Europeans

The modern humans emerged within eastern Africa some 150,000 years ago, spread temporarily into extreme southwest Asia and into southern Africa, and then through northern Africa into Europe around 40...

Researchers first to map gene that regulates adult stem cell growth

One big obstacle chemotherapy patients face is stem cell loss after treatments. This limits the dosage amount and types of che...

...ondary infection by other pathogenic bacteria, for example Clostridium difficile." Given the urgent need for new antibacterials to tackle staphylococcal infections, Dr Czaplewski believes that the research, supported by this 3.48 million, 33 month award, could result in a new medicine being fast-tracked int...
