Bacteria research offers hope for new vaccine against meningococci

...m has developed, it is now possible to rapidly and effectively monitor the function of various vaccine candidates and new drugs, obviating the numerous costly and time-consuming tests that have been necessary until now. At the same time, the system provides a clear picture of the process of infection. “With ...

Novel computed imaging technique uses blurry images to enhance view

... a fully focused, three-dimensional image." ISAM effectively extends the region of the image that is in focus, using information that was discarded in the past. "We have demonstrated that the discarded information can be computationally reconstructed to quickly create the desired image," Marks said. "We are ...

Targeting tumors the natural way

...consin-Madison scientists now report they can more effectively seek out and kill cancer cells while sparing healthy ones. The new tumor targeting strategy, presented today (March 25) at the annual national meeting of the American Chemical Society, cleverly harnesses one of the body's natural antibodies and immu...

Killing the messenger RNA -- But which one?

..., only 19 to 21 nucleotides in length, are able to effectively silence sometimes large sets of genes. They do this by specifically binding to and neutralizing another form of RNA called messenger RNA, responsible for conveying the information from genes to the cellular machinery that uses that information to cre...

New nanotechnology able to examine single molecules, aiding in determining gene expression

...NA sequencing. However, such processes could not effectively measure single gene transcripts—the building blocks of gene expression. With their new approach, the researchers of the work reported in Nanotechnology were able to isolate and identify individual transcript molecules—a sensitivity not achieved with ...

'Hidden-hero' microbes in soil, water may help naturally clean toxic sites

...ites nationwide -- and do so more economically and effectively than most conventional methods. "The stakes are high and the impact potentially huge," Kostka said. Together, those 7,000 U.S. sites encompass an estimated 1.7 trillion gallons of contaminated water -- that's about four times the nation's daily wa...

Cryoablation -- A new treatment option for some kidney tumor patients

...ecurrence. Also, the area being treated cannot be effectively monitored with computed tomography (CT) or ultrasound. The Mayo study findings show that cryoablation can be used for some larger tumors with simultaneous operation of multiple cryoprobes guided by ultrasound. The ablation margin (the edge of the f...

Immunization rates hit record high in poor countries

...provisional patent for a new method of cheaply and effectively spreading the fungus, and other similar "biological controls," that might beat back the adelgid without having to use expensive, toxic pesticides. They call their approach a "whey-based fungal micro-factory." Instead of growing fungi in a conventi...

Fungal factories may save hemlock forests

They call their approach a "whey-based fungal micro-factory." Instead of growing fungi in a conventi...

Scientists identify a candidate gene for osteoporosis

...howed that antibodies to the DARC protein, which effectively blocked the action of DARC , inhibited the formation of osteoclasts. Although the researchers have identified a number of DNA alterations in the DARC gene, they did not pinpoint the specific alteration that was responsible for the BMD differenc...

How fish mend a broken heart

... zebrafish, as opposed to other laboratory models, effectively regenerate [heart muscle]," the researchers concluded. Indeed, they added, mammalian hearts typically show insufficient blood vessel growth after a heart attack. "Experimental attempts to modify this deficiency are underway, including delivery of g...

Antibiotic treats lymphoma of the eye

The common antibiotic doxycycline effectively treats a type of lymphoma associated with chlamydia infection, according to a study in the October 4 issue of the Journal of the National Cancer Institute. Ocular adnexal lymphoma of the MALT-type (OAL) is a kind of cancer of the eyelids and rel...

Older fathers more likely to have autistic children

...development of children; however, few studies have effectively examined the effect of mothers' and especially fathers' ages on autism. Abraham Reichenberg, Ph.D., of the Mount Sinai School of Medicine, New York, and Institute of Psychiatry, King's College London, and colleagues evaluated this association in ...

'Protecting virus' offers instant flu protection and converts flu infections into their own vaccines

...fection ? means that the new invading influenza is effectively crowded out by the 'protecting virus'. This vastly slows the progress of the new infection, prevents flu symptoms, and gives the body time to develop an immune response to the harmful new invader. In effect the protecting virus converts the virulen...

Peering into the shadow world of RNA

Diabetes slows nerve recovery after heart transplant

...not produce enough insulin or when the body cannot effectively use the insulin it produces. Such a deficiency results in increased concentrations of glucose (sugar) in the blood, which can damage many of the body's systems. Diabetes mellitus is a known major risk factor of heart disease, negatively affecting the...

New drug blocks influenza, including bird flu virus

...y of a peptide -- a small protein molecule -- that effectively blocks the influenza virus from attaching to and entering the cells of its host, thwarting its ability to replicate and infect more cells. The new finding is important because it could make available a class of new antiviral drugs to prevent and tr...

Researchers identify neurons that assign value during learning

...ntal trick to activate certain sets of neurons and effectively substitute activation of these cells for positive or negative experiences, researchers have been able to identify neurons in the fruit fly Drosophila that are responsible for assigning value to stimuli during so-called associative learning. The findi...

Selecting life: Scientists find new way to search for origin of life

...y Ion Mass Spectrometry (ToF-SIMS). The instrument effectively blasts a sample with ionized particles and fragments the surface-bound molecules and topmost mineral layer. The mass spectrometer allows the researchers to determine what's there. "ToF-SIMS will also allow us to detect the organic molecules that bind...

New technology to speed up research into Huntington's disease

...e screen will also allow researchers to study more effectively the cognitive difficulties in other neurodegenerative disorders such as in Alzheimer's and CJD. Huntington's disease is a genetic disease affecting around 8 in 100,000 people. It is characterised by a progressive decline in cognitive functioning (...
