Biologists ID defense mechanism of leading fungal pathogen

... has three copies, and it alone has a mechanism to react to increased NO levels by producing more NO-scavengers," said lead researcher Mike Gustin, associate professor of biochemistry and cell biology. "If we can identify the signaling mechanism it uses, that would give us one more useful target for new dr...

A fly's taste experience is much like our own

...need to know where the food is located in order to react properly," Scott said. "If a fly tastes sugar with its leg, it automatically extends its proboscis and eats. If it detects sugar with its proboscis, it just eats." Scott noted that flies, like mammals, probably also have sour and salt taste receptors...

Lupus Research Institute awards $3 million in novel research grants to further new science in lupus

...ulonephritis, Dr. Paul will learn how kidney cells react to an autoimmune attack. She will examine early kidney lesions before clinical signs of the disease are present, with the goal of predicting the development of kidney disease in lupus patients. David S.

Study suggests double punch could more efficiently kill viruses

...es to kill the virus. The body is then prepared to react if exposed to live virus. However, some viruses, like human immunodeficiency virus (HIV) and smallpox, travel inside cells where antibodies cannot penetrate. These viruses are transferred from cell to cell and only specialized white blood cells calle...

Mouse study yields clue to why liver is less prone to rejection, say Pitt researchers

...ual patterns of other molecules. TLR-4 is known to react to lipopolysaccharide (LPS), a component found in the cell wall of bacteria. Reacting to LPS sets in motion a cascade of immune events that begins with the rapid maturation of dendritic cells. Because of the liver's position downstream from the inte...

'Nanobodies' herald a new era in cancer therapy

...ing from bacteria and viruses. Antibodies can also react with tumor-specific substances that appear only on the cancer cell membrane. These ingenious antibodies seek out and bind very specifically to the cancer cells. As a result, the tumor is removed in a highly targeted, specific manner. At the moment,...

...nally "orthogonal" paira tRNA/synthetase pair that react with each other but not with endogenous E. coli pairs. So they devised a methodology to evolve the specificity of the orthogonal synthetase to selectively accept unnatural amino acids. Starting with a tRNA/synthetase pair from the organism Methano...

Functional genomics enables easy target identification and drives drug discovery

...wherein, molecular building blocks are designed to react together selectively and covalently. With an increasing number of new molecular entities (NMEs) entering clinical trials by 2008, a 65 percent increase in NMEs entering the market is expected innovative techniques for 'fast track' drug development ...

Gene-based screen sorts cancer cases, say Stanford researchers

... However, two people with the same score may still react differently to treatment. One thought has been that a genetic screen may fine-tune the distinction between the most aggressive and least aggressive cancers. "It makes a big difference in your treatment decisions if you think you have a high chance of...

Biological computer diagnoses cancer and produces drug in a test tube

The Weizmann Institute of Science team that developed the computer published these results today in Nature. Headed by Prof. Ehud Shapiro, of the Departments of Computer Sciences and Applied Mat...

ORNL's nanobiosensor technology gives new access to living cells molecular processes

...s many other applications for looking at how cells react when they are treated with a drug or invaded by a biological pathogen. This has important implications ranging from drug therapy development to national security, environmental protection and a better understanding of molecular biology at a systems l...

Brain areas identified that 'decode' emotions of others

...l this brain activity happen when people passively react to an emotional stimulus, it also occurs when they actively search for mental state information," says Dr. Sabbagh. Problems in "mental state decoding" are associated with developmental disorders such as autism. As a next step, the researchers plan ...

Keck Futures Initiative announces grant recipients

...ngoing experimental work in his laboratory. Cells react to a wide variety of stimuli, such as chemical messages sent by other cells. Each different stimulus triggers a distinct cellular response; yet cells use a limited number of component proteins to transmit these numerous signals. Bardwell will inves...

"That's just evolution in motion. With negative cross-resistance, we're buying time for the commercial life of anothe...

Carnegie Mellon U. develops microgel to recover enzymes for manufacturing, research assays

...re, large chemicals cannot enter a dense matrix to react with embedded enzymes. The microgel developed by Armitage and Patterson bypasses these limitations. The enzyme is tightly connected to the microgel matrix, but remains fully functional. Molecules can diffuse into the porous microgel and undergo che...

For the sake of land and climate, coaxing soil to soak up carbon

...droxybenzoic acids, to form quinones. The quinones react with amino acids released by soil microbes to form complex, durable molecules called humic polymers. "Because humic polymers are less easily degraded by microbes than the precursor molecules, they survive to diffuse into small pores in soil aggregate...
