Coming soon: 3-D imaging that flies 'through' and 'around' cancer

...copy and Colonoscopy." This imaging technique "may add important diagnostic information that may herald new applications for the use of PET/CT," he noted. In addition, its diagnostic value was demonstrated in one case in which it revealed a cancer lesion that had not been detected by PET, CT or PET/CT im...

Genetic snooze button governs timing of spring flowers

...the process of vernalization, and their hope is to add to knowledge of other cold-regulated processes such as the regulation of bud dormancy in trees. Bud dormancy may be similar to vernalization or, the Wisconsin scientists adds, it may be controlled by a completely different mechanism. "But our stud...

UC Davis researchers reveal apples' protective ways

Doctors have long been encouraging Americans to add more fruits and vegetables to their daily diets. Now, UC Davis researchers have discovered one way in which flavonoid-rich apples inhibit the kinds of cellular activity that leads to the development of chronic diseases, including heart disease and ag...

New strategy rapidly identifies cancer targets

...ruker is already testing the idea. "Now we know to add JAK3 to the mutations we screen for in our leukemia patients and should look to see if JAK3 mutations are present in other cancers," he said. ...

A new look at the state of the oceans

...s to the data base enables all registered users to add their own images and data, and to supplement existing data records. All newly entered data are reviewed, and, if necessary, evaluated by experts. This not only facilitates the fast development and expansion of the data base, but also leads to a high ...

Molecular DNA switch found to be the same for all life

...lex," said Berger. "These other proteins can help add layers of complexity, such as assisting with helicase loading or inactivating the initiator after replication has begun. The open rings also probably allow DNA to interact with the interior of the initiator assembly." Bacterial cells, like the cell...

NHGRI announces latest sequencing targets

...s of a set of organisms whose genome sequence will add to the comprehensive strategic list of priority targets for genomic sequencing by the NHGRI's Large-Scale Sequencing program. Seven mammals which have been previously approved to be sequenced at low-density genome coverage have been ...

Survivors of childhood polio do well decades later as they age

...ld deficits. Very few had to change their homes or add adaptive equipment. Those who had weakness problems during our study had a larger deficit at the end of their childhood disease, making them more likely to develop symptoms. So, as deficits at the end of the disease increase, the probability of exper...

How ancient whales lost their legs, got sleek and conquered the oceans

...that says minor changes over vast expanses of time add up to big changes. And while Sonic hedgehog's role in the evolution of hind limbs in ancient whales is becoming apparent, it is still not fully defined. "It's clear when ancient whales lost all vestiges of the limb it was probably triggered by loss ...

Bubbles go high-tech to fight tumors

...m. Now, University of Michigan researchers hope to add a more sophisticated application to the list---gas bubbles used like corks to block oxygen flow to tumors, or to deliver drugs. The process of blocking blood flow to a tumor is called embolization, and using gas bubbles is a new technique in embol...

Bones hold the key to blood renewal

...crease mainly in stem cell release. These findings add a new dimension to our understanding of the processes of renewal and breakdown in the body, and the relationship between blood-forming stem cells, bone, and the immune system. In some forms of osteoporosis, autoimmune arthritis, and cancer that has m...

Technique speeds up detecting, treating wound bacteria

...hose detectable by PCR. Yet. "We will definitely add to the list," he said. "We are currently basing our selection of organisms to detect (through real-time PCR) on the current literature on surgical infections, but we expect to find many more organisms with the molecular techniques we will use." Fin...

Honey helps problem wounds

...s an antiseptic effect: when producing honey, bees add an enzyme called glucose-oxidase. This enzyme ensures that small amounts of hydrogen peroxide, an effective antiseptic, are constantly being formed from the sugar in the honey. The advantage over the hydrogen peroxide from the chemist's is that small...

Iron critical to ocean productivity, carbon uptake

...f growth and then it plateaus," he said. "Then you add a bit more iron, and the phytoplankton respond a bit more. Then you add a third shot, and it triggers some more modest growth. But at the same time you're promoting phytopl...

Alaska seal pup diet may hold key to decline of population

...n the critical predictor of whether the seal would add body mass and body fat, Polasek explained. Seals weighing less than 26 kilos (about 12 pounds) showed little progress in gaining weight and even lost blubber, regardless of which diet they were on. On the other hand, the study's largest seal, which ...

Study fishes out new role for prostaglandins

A new study by Vanderbilt researchers reveals that prostaglandins help choreograph the intricate cell movements during early embryonic development in zebrafish, highlighting how perturbations i...

Imaging study links key genetic risk for Alzheimer's disease to myelin breakdown

In addition, the study demonstrates how genetic testing coupled with non-invasive evaluation of myelin breakdown through magnet...

All placebos not created alike

Though the results of this study add evidence pointing to the existence of a placebo effect in a clinical environment, Kaptchuk does not recommend the use of placebos with patients or deception in the doctor-patient encounter. The aim is to understand how the ritual of healing affects h...

Virginia Bioinformatics Institutes launches microbial database

...n interface is available for registered members to add or edit annotations. The database will be expanded in 2006 to include genome sequences for the fungal pathogen Alternaria brassicicola and the oomycete pathogen Hyaloperonospora parasitica, both of which can infect the model plant Arabidopsis. In a...

New insight into machinery of immune cells' 'tentacles'

...g stimuli, found the researchers. "These findings add important new players in the regulatory pathway downstream of Rac," said Pendergast. "And since immune system activation depends critically on the formation of the synapse, these new players give us more targets for drugs to treat both immune deficie...
