Revolutionary nanotechnology illuminates brain cells at work

...versity are the first to overcome this obstacle by successfully applying genetic nanotechnology using molecular sensors to view changes in brain chemical levels. The sensors alter their 3-dimensional form upon binding with the chemical, which is then visible via a process known as fluorescence resonance energy tr...

Emergence of cancer as major cause of childhood death in developing countries is not being adequately addressed

...xample, in parts of Africa it might be possible to successfully treat children who have Burkitt’s lymphoma using a single drug, cyclophosphamide. Such twinning projects can be supported initially by the partner in the more affluent country, the authors say. Local charitable groups can raise funds to support an on...

Technique may allow cancer patients to freeze eggs, preserving fertility before starting treatment

...ed to the uterus in the same procedure that's used successfully when couples freeze embryos. When eggs are warmed after vitrification, fertilization rates with conventional IVF are low. Instead, researchers have found, a single sperm cell must be injected into a single oocyte, a technique called intracytoplasmic...

Youth With HIV Take More Risks After New Meds Introduced

...HAART, were introduced in 1996. The new drugs have successfully lowered virus levels and prolonged the lives of thousands of HIV patients. Although the new study does not prove that the introduction of HAART is the cause of increased risky behavior, "these findings indicate the need for continued attention to th...

Test for early detection of prostate cancer shows promise

... called EPCA or early prostate cancer antigen, can successfully detect prostate cancer in its earliest stages. At the same time, the marker successfully avoids the problem of false positive results that plagues prostate-specific antigen (PSA) testing. ...

CoPub Mapper: mining MEDLINE based on search term co-publication

...ying of co-published genes and keywords and can be successfully used to cluster predefined groups of genes and microarray data. ...

Bioelectronic ‘signatures?hold key to DNA mutations

...Biodesign Institute at ASU, led a team effort that successfully merged work in the fields of biosensors, electronics, and nanotechnology to fashion nanocrystals that can act as “DNA biosensors?by electronically recognizing subtle mutations in the DNA. This creates enormous potential for applications such as the d...

Duke engineers develop new 3-D cardiac imaging probe

...ling for 64 transducer elements whereas our design successfully incorporates 8 times that number." The probe generates ultrasound at 5 million vibrations per second, which, combined with the 504 sensors, provides great sensitivity and a sharp image, Smith said. And because the image is large enough to encompass ...

Are rice and wheat behind China's population boom?

...r and knowledge of water management practices. "By successfully manipulating rice production to the extent that these ancient people did, in combination with millet and wheat, helps explain the foundation of China's huge population today." ...

NIAID begins clinical trial of West Nile virus vaccine

..., Ph.D., of Fort Collins, CO, that has been tested successfully in a variety of animals, including mice, horses and American crows. Two other human WNV vaccines developed with NIAID support are currently in Phase I clinical trials. Called chimeric vaccines, these vaccines combine genes of the West Nile virus wit...

Genetic therapy reverses nervous system damage in animal model of inherited human disease

...disease affecting the central nervous system to be successfully treated in an animal larger than mice and rats. If this approach can be successfully applied to humans, say the researchers, it might one day treat an entire class of diseases called ly...

Friendly bacteria in humans may protect against HIV

...eminine products," says Tao. "If the method can be successfully developed and applied, the global spread of HIV can be controlled rapidly, effectively and safely." "The major roadblock in the development of this technology is the lack of financial support. Drug companies and venture capitalists are not intereste...

Migratory songbirds have a specialized night-vision brain area

...Foundation's Waterman Award to Jarvis. To migrate successfully over thousands of miles at night, night-migratory birds need to see where they fly, as well as navigate by stars and the earth's magnetic field. Surprisingly, Jarvis said, recent scientific evidence has suggested that birds have specialized molecules...

Symbiotic bacteria protect hunting wasps from fungal infestation

...hat potentially sheds light on how bacteria can be successfully utilized by higher organisms in defensive mechanisms against other microbes. In the new work, researchers show that a solitary ground-nesting wasp, the European beewolf, harbors Streptomyces bacteria in unique structures within its antennae and that ...

15-year hunt finds cause of pseudothalidomide syndrome

...from Colombia, the United States and elsewhere has successfully completed a 15-year-plus search for the genetic problems behind the very rare Roberts syndrome, whose physical manifestations often include cleft lip and palate and shortened limbs that resemble those of babies whose mothers took thalidomide during p...

Researchers find gene that may be at root of potato blight

...ists found that the leaves containing the R3a gene successfully resisted late blight infection when exposed to P. infestans races that carried the Avr3a gene. However, some races of P. infestans with mutations in their Avr3a gene escaped the resistance response triggered by R3a. Further laboratory analysis showe...

Ancient immune defense mechanism is no match for HIV-1

Human Eggs Can Develop From Ovarian Surface Cells In Vitro

...tes cultured in this way are viable and went on to successfully complete the first meiotic division to become mature human eggs -- capable of being fertilized and developing into an embryo. These in vitro findings support earlier in vivo studies by Bukovsky and colleagues that OSE cells are bipotent; capable of d...

At the molecular level, the predator is the prey

...ene within this group of beasts." For TTX to bind successfully to the sodium channel, the toxin needs something to bind to. At this moment in the garter snake's evolutionary history, TTX infiltrates a hole on tsNa(V)1.4's surface, binding to an aromatic amino acid and causing enough of a change in the sodium cha...
