Common blood test can help distinguish between mononucleosis and tonsillitis

...nonucleosis and bacterial tonsillitis, potentially guiding treatment decisions, according to an article in the January issue of Archives of Otolaryngology–Head & Neck Surgery, one of the JAMA/Archives journals. Acute tonsillitis (inflammation of the tonsils) and infectious mononucleosis (caused by the E...

Magnetic system could be key to surgery without scars

...he technology may solve the fundamental problem of guiding instruments through the abdomen for natural orifice surgery, which now inserts the instruments through the throat, colon or vagina. “The current state of the art for laparoscopic surgery requires four or five holes. The question behind this is, ca...

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

...anded. These are very significant results that are guiding my own research as well as many other investigators in the field." Once Hazen and coworkers have identified molecule/surface pairs of interest with the DNA microarray and ToF-SIMS, an arsenal of other techniques can be used to look at the details ...

Gene-bender proteins may sway to DNA

...about the role that the DNA "bendability" plays in guiding the correct bending protein to the appropriate site on the DNA. Ansari said the research adds to the basic understanding of how proteins recognize a specific binding site. "Gaining better insights into protein-DNA interactions that control all a...

Paying attention sets off symphony of cell synchronization

...ge the stimulus but can make it more effective for guiding our behavior," Grabowecky said. "When you need to dig deep to summon that extra ounce of attention, it's as if you engage a symphony of brain activity that can come to your rescue as millions of neurons together make the music that represents a vi...

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

...ial for presurgical visualization, particularly in guiding biopsies," explained the co-author of "'Flying Through'" and 'Flying Around' a PET/CT Scan: Pilot Study and Development of 3-D Integrated 18F-FDG PET/CT for Virtual Bronchoscopy and Colonoscopy." This imaging technique "may add important diagnostic i...

New study reveals signaling pathways required for expansion of pancreas stem cells

...nal of Biological Chemistry. "Our work focused on guiding stem cells, or pancreas progenitors, to differentiate into beta cells. This approach required that we increase the number of pancreas progenitors by finding the signals that cause them to proliferate. It also required that we understand the 'cues' th...

Primates take weather into account when searching for fruits

...r stored knowledge of recent weather as a tool for guiding their foraging behavior when searching for ripening fruit. The work, which potentially informs our understanding of how cognitive skills developed in humans and other primates, is reported by Karline Janmaat, Richard Byrne, and Klaus Zuberbühler of t...

Adult stem cells are touchy-feely, need environmental clues

... the physical microenvironment is also crucial for guiding the cells through differentiation. According to Adam Engler, the first author on the study and a graduate student in the School of Engineering and Applied Science, soft microenvironments, that mimic the brain, guide the cells toward becoming neuron...

Liquid crystals show promise in controlling embryonic stem cells

...ain challenge facing stem cell research is that of guiding differentiation along these well-defined, controlled lineages. Stem cells grown in the laboratory tend to differentiate in an uncontrolled manner, resulting in a mixture of cells of little medical use. Now, University of Wisconsin-Madison researche...

UF scientists trace origin of shark's electric sense

...e has shown which molecules may be responsible for guiding the development of the receptors of the lateral line system. I think this will hold true and is a very important finding. But I'm skeptical about the claim the neural crest gives rise to electroreceptors. It still requires a definitive experiment, wh...

For the first time: Longevity modulated without disrupting life-sustaining function

...-1 is missing, that is. Without Smk-1 to provide guiding assistance, DAF-16 is unable to slow down the aging process, and the worms die young. "These mutants are shorter lived because they are unable to respond appropriately to oxidative stress, but they are just as resistant to heat stress as wild type w...

New gene reduces retinal degeneration in fruit flies

...related proteins in mammals that are essential for guiding certain nerves during development and for responding to stimuli including heat, taste and sound. By shining bright light onto and recording electrical changes in single nerve cells in the fly eye, researchers found that neurons carrying a mutation ...
