New way of tracking muscle damage from radiation

...d the presence of a nearby tumor. "We hope that detecting these changes at such an early stage may help clinicians predict which patients need an intervention to prevent late damage," Krasin said. Soft tissue sarcomas are cancers that arise in muscles, fat, blood vessels and other soft tissues. Ewing sarco...

Living view in animals shows how cells decide to make proteins

...press different proteins in different amounts, and detecting such differences in cell cultures can be exceedingly difficult, he said. "This is a powerful tool to apply to mouse genetics to learn when and where in the animals' bodies alternative splicing decisions are made and, eventually, to learn what fact...

T-ray breakthrough could make detecting disease far easier

St. Jude announces breakthrough in eye cancer treatment

...tina, which is the part of the eye responsible for detecting light and color. The cancer is fatal if left untreated. The new treatment holds promise for a simpler, more effective and less-toxic treatment for retinoblastoma that would eliminate the need for the current, complex therapy, according to senior a...

Chromosomal microarray analysis proves accurate

...dren, they find that it is remarkably sensitive in detecting abnormalities in individual chromosomes, according to a report that appears online today in the journal Public Library of Science ONE. "Chromosomal microarray analysis is far better at picking up these abnormalities than other common methods," said ...

A revolution in the monitoring of unborn babies

... we can monitor them, the greater the chance of us detecting that they are running into difficulties before it is too late to help them. This may involve urgent delivery of the fetus.? The device will be especially helpful in monitoring fetuses whose mothers have medical conditions like diabetes, autoimmune ...

Biologically inspired sensors can augment sonar, vision system in submarines

...ching those of their biological counterpart. "By detecting changes in water pressure and movement, the device can supplement sonar and vision systems in submarines and underwater robots," said Liu, who also is affiliated with the university’s Beckman Institute for Advanced Science and Technology, the Institu...

Using dental X-rays to detect osteoporosis

...s team developed the largely automated approach to detecting the disease during a three-year, EU-funded collabo...developed an innovative software-based approach to detecting osteoporosis using routine dental x-rays, by automatically analyzing specific characteristics of the...

Selective marker found to indicate aggressive form of breast cancer

...nt next step will be finding an efficient means of detecting nestin in a clinical screening setting. While it seems unlikely that a blood test would be sufficient, DiRenzo believes that a non-invasive test that collects samples from mammary ducts may enable the development of a screening tool for at-risk patie...

Penn study on olfactory nerve cells shows why we smell better when we sniff

... of stimuli, our sense of smell works double duty, detecting both chemical and mechanical stimuli to improve how we smell, according to University of Pennsylvania School of Medicine researchers in the March issue of Nature Neuroscience. This finding, plus the fact that both types of stimuli produce reaction ...

A new study of living cells could revolutionize the way we test drugs

Researchers have made a breakthrough by detecting the electrical equivalent of a living cell’s last gasp. The work takes them a step closer to both seeing the ‘heartbeat?of a living cell and a new way to test drugs. To stay alive, individual biological cells must transfer electrically charged part...

Sheffield scientists light up bacteria

...ndustries in general, as well as those involved in detecting infection in battlefield conditions and bacterial contamination, whether accidental or deliberate. Currently identifying bacterial infection takes several days and requires swabbing and culturing of bacterial swabs as well as the use of speciali...

Mimicking how the brain recognizes street scenes

... to detect faces or recognize textures are poor at detecting cars. In the biological model, the same algorithm can learn to detect widely different types of objects. To test the model, the team presented full street scenes consisting of previously unseen examples from the Street Scene Database. The model s...

Researchers identify ovarian cancer biomarkers

... types as a potential screening tool. A new way of detecting ovarian cancer could make a significant dent in this disease, where 70 percent of patients are diagnosed after the tumor has grown large or spread. There are few or no symptoms early in the disease and no effective screening tests. Early diagnosis is...

Discovery of new cave millipedes casts light on Arizona cave ecology

...ropod Biodiversity, is also developing methods for detecting caves using thermal remote sensing imagery. Once procedures are developed, these techniques ultimately will be used to find caves on Mars. He is also studying extreme cave-adapted life forms by characterizing their habitats to determine how they exis...

Get a whiff of this: Smell test could sniff out serious health problems

... normal sense of smell, the size of the sniff when detecting an odor is cut in half. For someone who cannot detect odor, the size of the sniff for just air and the size of the sniff for an odor are the same.? In humans, Frank says the sense of smell is one of our less robust senses. He says it’s more suscept...

Anthrax paralyzes immune cells with lethal toxin, UF research shows

...ave more than a common cold. The current method of detecting anthrax relies on lab cultures that can take days to complete. "We're looking for approaches to detect anthrax earlier in the blood," said Russell During, Ph.D., a postdoctoral fellow at UF's College of Medicine. "We're trying to develop a test th...

Resistant HIV quickly hides in infants' cells

...o a need for new and widely accessible methods for detecting HIV infection in infants, whether resistant or not," he pointed out, "since transplacental transfer of maternal antibodies precludes the use of antibody detection methods." Affordable techniques also are necessary to reliably detect resistant HIV in...

454 sequencing identifies HIV drug resistance at early stage

...e technology available to clinicians is limited to detecting resistance mutations that are present at levels of approximately 20% or greater in the circulating viral population in a patient. Thus, the current technology used in the clinic may miss many low-level resistant HIV strains which can grow rapidly und...
