Where bacteria get their genes

... their genomic sequence data. The researchers then computed family trees, taking into account the acquired genes, and matched the trees to an established reference tree. For all genes, the match was about 95 percent. This showed that the widespread mechanism of lateral gene transfer does not interfere with th...

Retina adapts to seek the unexpected, ignore the commonplace

...neural responses to novel stimuli, the researchers computed the sensitivity of individual ganglion cells to various scenes. For most cells, sensitivity to a novel scene was greater than sensitivity to control scenes to which the animals had already been exposed, a gap that grew gradually in the seconds after...

New study shows SARS can infect brain tissue

...system symptoms, like restlessness and delirium. A computed tomography scan indicated brain damage. He died about a month after being hospitalized, and his brain tissue was examined and found to contain the SARS coronavirus. The researchers also discovered a high level of Mig, a type of immune system regulato...

The nude mouse tale: Omega-3 fats save the life of a terminal cancer patient

...f what they were in 2000, according to last year's computed tomography (CT) scans. What worked with DH is not a common medical treatment such as chemotherapy or surgical excision. It was a nutritional intervention, drastically increasing the patient's intake of omega-3 fatty acids, which are often found in ...

Technique makes it easier to see mouse embryo in all its glory

...s digitally scanned at high resolution using x-ray computed tomography. Computational methods are applied to analyze embryo organs for defects. "From the moment of conception, the mice under study are genetically programmed to develop tumors," Dr. Keller said. "Intentional disruption of specific genes can ...

Pittsburgh researchers discover that certain chemicals in the blood may indicate brain injury

...uld benefit from additional evaluation with a head computed tomography (CT) scan. Identifying cases of SBS that might otherwise be missed has important implications for decreasing morbidity and mortality. The findings are published in the February issue of Pediatrics, the official journal of the American Aca...

Study suggests that publicly available genome data may contain small but significant errors

...pombe genome was compared to the corresponding map computed from publicly available S. pombe sequence. The comparison showed a small number of significant discrepancies between their results and that of the map derived from the public sequence released in 2002. S. pombe's genome is only about 14 million bases...

New MRI technique shows emphysema in asymptomatic smokers

... changes than even the current modality of choice, computed tomography (CT). "With this technology, we have shown that it is possible to measure the severity of emphysema and its progression through time without the radiation exposure of lung CT tests," said Sean B. Fain, Ph.D., lead author and assistant pro...

NYU algorithm enhances ability to detect cancer genes

... the cancer in these patients. In other words, the computed score measures how likely it is for a particular genomic interval to be a tumor suppressor gene implicated in the disease. In order to validate their algorithm, the authors produced a high fidelity in silico model of cancer, and checked how well they...

Patients to benefit from novel technology revolutionizing high-speed molecular imaging

...new D-SPECT camera approaches the imaging speed of computed tomography (CT), it will become economical to have functional and anatomic imaging in line (as a hybrid image) and in near real time for developing combined single photon emission computerized tomography (SPECT) and CT images," added the co-author of...

Ohio University researchers discover evolutionary oddity in flamingos

...-D view of the bird's head was created using a new computed tomography (CT) scanning technique developed by the Ohio University team that highlights blood vessel anatomy. The researchers noticed large oval masses of erectile tissue located on the floor of the mouth on either side of the tongue. "No one e...

Radiologists attempt to solve mystery of Tut's demise

Egyptian radiologists who performed the first-ever computed tomography (CT) evaluation of King Tutankhamun’s mummy believe they have solved the mystery of how the ancient pharaoh died. The CT images and results of their study were presented today at the annual meeting of the Radiological Society of North Amer...

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

...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 frozen tissue) can be acc...

Novel computed imaging technique uses blurry images to enhance view

Study finds surfing safer than soccer

.... In the first study of its kind, researchers have computed the rate of injury among competitive surfers and found they are less prone to harm than collegiate soccer or basketball players. Led by researchers at Rhode Island Hospital and Brown Medical School, the findings of the study are published in the Janu...

Novel system developed to turn data into real-time, interactive 3-D images

From magnetic resonance imaging (MRI) to computed tomography (CT) scan, images of the body’s tissues and organs have become the primary tools physicians use to diagnose disease and make recommendations for effective treatment. New, innovative data display technology developed at Kent State Univer...

'Virtual autopsy' helps identify drowning as cause of death

"Virtual autopsy" performed with multidetector computed tomography (MDCT) can aid forensics teams in determining if a person has drowned, according to a study published in the June issue of Radiology. MDCT is comparable to conventional autopsy in demonstrating airway froth and sediment that are indicativ...

3-D ultrasound scanner provides in-depth view of the brain

...bedside evaluation of critically ill patients when computed tomography (CT) and magnetic resonance imaging (MRI) equipment is unavailable, the researchers said. They report the development in a forthcoming issue of the journal Ultrasound in Medicine & Biology, which is currently available online. The work...
