Circulating stem cells play small role in lung repair

...including lung tissue, Zander said, and this study provides evidence of differentiation. Researchers examined lung biopsy specimens from seven male transplant recipients who had received lungs from female donors. They analyzed the origins of type II pneumocytes, a stem cell involved in the complex processes ...

Combination therapy leads to partial recovery from spinal cord injury in rats

... the National Institutes of Health. The new study provides the best demonstration to date that producing a nerve-insulating substance called myelin can lead to functional improvements in animals with spinal cord injury. Previous studies have shown that the loss of myelin around nerve fibers contributes to th...

Morphine for Chest Pain Increases Death Risk

...tals on treatments for patients with non-STEMI and provides quarterly feedback to hospitals with the ultimate goal of improving adherence to the ACC/AHA treatment guidelines and patient outcomes. The CRUSADE registry is funded by Millennium Pharmaceuticals, Cambridge, Mass., and Schering Corp, Kenilworth, N....

Proteomics brings researchers closer to understanding microbes that produce acid mine drainage

...four of them new to science. The current study now provides nearly half the proteins predicted to be produced by the dominant bacteria, a Leptospirillum group II bacterium, and a smaller proportion from the other bacteria. The lesser coverage of the minor bacteria in the community is due in part because their...

Mechanism for the captation of nutrients in plants- unknown to date

...lluloses, etc.), basic knowledge of this mechanism provides great tips for the rational design of experiments aimed at enhancing vegetable species in the interest of humanity. One of the great questions thrown up by the fact that saccharose pick-up is produced via endocitosis is, fundamentally, to find out i...

Late peak may have prevented severe flu season from becoming worse

...a was provided by ACTrackerTM, an online tool that provides national estimates of hospital and drug utilization approximately 45 days after the end of each month, making the estimates the most timely and current of their kind. In the 2004-2005 flu season, daily CAP discharges peaked at an average of about 7,...

Specialized immune-system B cells play double-barreled role

... system in which one kind of B-1 cell consistently provides a low level of protection, while the other specifically responds to an infection to help eliminate it." According to Haas and Tedder, the findings offer potential insights into the mechanism of vaccine action. For example, the new insights into the ...

Modified collagen could yield important medical applications

...mmon protein. Collagen promotes blood clotting and provides the sponge-like scaffold upon which cells build nerves, bones and skin. Because it is non-toxic, dissolves naturally over time and rarely triggers rejection, collagen is commonly used in cosmetics, drug delivery systems and biocompatible coatings. ...

ORNL, UC Berkeley unravel real-world clues to Earth's mysteries

...search team acknowledges that, although this study provides interesting details of microbial community structure and function, a great deal of work remains to more fully explore the spatial and temporal aspects of how such a community grows, ages and adapts to its environment. ...

Unusual antibiotics show promise against deadly 'superbugs'

...mmon protein. Collagen promotes blood clotting and provides the sponge-like scaffold upon which cells build nerves, bones and skin. Because it is non-toxic, dissolves naturally over time and rarely triggers rejection, collagen is commonly used in cosmetics, drug delivery systems and biocompatible coatings. ...

Motor transport in bio-nano systems

...point into the same direction. Such an arrangement provides many parallel tracks for the molecular motors and,...ffusion of motors at regular patterns of filaments provides an instructive example: When integrated into existing microarrays for DNA and RNA hybridization, the...

Study shows humans have ability to track odors, much like bloodhounds

... is that the experimental set-up, with a mask that provides separate air flow to each nostril, is artificial. How behaviorally relevant is that?" said Porter. Subsequent experiments not yet reported, however, provide additional support for their hypothesis that the ability to localize odors to one nostril or ...

Montreal researchers probe the genetic basis of memory

...ed in the August 25th issue of the journal Nature, provides the first genetic evidence that protein synthesis is critical for the regulation of memory formation. This new discovery is the fruit of an international collaboration. The work of McGill researchers Nahum Sonenberg, Karim Nader, Wayne Sossin and C...

Researchers use 3-D imaging system to unveil swimming behavior of microscopic plankton

...implies that this energetically demanding behavior provides significant, yet poorly understood benefits. Revealing those benefits and the nature of depth sensing will be a major and exciting challenge for future research in zooplankton ecology and evolution." ...

New Vaccine To Be Used For First Time In Polio Outbreak Response

... against all three types of wild poliovirus, mOPV1 provides a greater immunity to type 1 wild poliovirus with fewer doses. Use of mOPV1 is expected during a nationwide immunization campaign in the second half of May. Yemen had already conducted a mass campaign on 11-14 April, as the country was considered to ...

Researchers Discover That Microbes Can Produce Miniature Electrical Wires

... cell onto metals or electrodes. This new research provides an explanation of how this can happen. Previous studies in Lovley's laboratory demonstrated that Geobacter produces fine, hairlike structures, known as pili, on just one side of the cell. Lovley's team speculated that the pili might be miniature wir...

New insight into autoimmune disease: Bacterial infections promote recognition of self-glycolipids

New defibrillator signals doctor of patient's irregular heartbeat or device malfunction

...wer in ICD-treated patients. "The new ICD provides faster delivery of care to patients and also reduces the number of times a patient has to go to the doctor's office for follow-up visits," said Varma, who specializes in treatment of arrhythmias. Because patients' heart muscle pumping action can be ...
