Bioartificial kidney under study at MCG

...ibers into the solution. The now-dirty solution is discarded and the cleaner blood is given back to the patient. In the study, all patients receive this standard approach to cleaning the blood. But two-thirds of the study participants take the additional step of having the liquid portion of their filtered blo...

UCSD team discovers specialized, rare heart stem cells in newborns

...e found in regions of the atrium that are normally discarded during routine cardiac surgery, the discovery raises the possibility that an individual could receive their own cardiac stem cells to correct a wide spectrum of pediatric cardiac diseases, according to co-first authors Moretti and Karl-Ludwig Laugwit...

Rare surgery performed to remove pancreas, prevent diabetes

...roducing islets of Langerhans would necessarily be discarded along with the rest of the organ. Patients without functioning islet cells have to take insulin for life. Retrieving and relocating the natural insulin-producing cells from the pancreas saves patients from the complications of severe, poorly-controll...

Adult bone marrow must be harvested from living donors through an invasive surgical procedure. Finally, cord blood cells are less mature than adult bone marrow cells and thus do not need to perfectly mat...

UN environmental agency steps up battle against marine pollution

Coastal pollution, including plastic waste, discarded lead-acid batteries and used oils and lubricants, will come under renewed attack under a new agreement signed by the United Nations environmental agency and an international treaty body controlling hazardous wastes. The Memorandum of Understanding, s...

Researchers Find New Technique To Identify Fetal Genetic Material From Amniotic Fluid

Researchers track down cause of a disfiguring bone disorder

...on play a biological role, or they would have been discarded as organisms evolved. By introducing the conserved segments into cells similar to osteoblasts (bone-forming cells), the team found that a 250-base-pair conserved region named ECR5 was able to drive SOST expression. "This study represents a clear and...

Modification of program enables prediction of gene transcription

...ost of this extra-long untranslated region is then discarded by splicing the 5' untranslated region (UTR). All present gene finding systems ?except for N-SCAN ?either ignore the UTR splice sites or incorrectly incorporate them into some protein-coding segment, making gene prediction a none-too-sure industry. ...

Discarded placentas deliver researchers promising cells similar to embryonic stem cells

Routinely discarded as medical waste, placental tissue could feasibly ...ore than 4 million live births each year. For each discarded placenta, the researchers calculate there are about 300 million amniotic epithelial cells that poten...

Center releases new public survey on stem cells

...on of fertility treatments that would otherwise be discarded or kept in frozen storage; a ban on the use of Federal funds to create new stem cells using these embryos currently is in effect, and various pieces of legislation pending in Congress would either extend this ban or relax it. A survey of 2,212 Amer...

Genetic testing still smart choice, despite uncertainties

...stimate less than 3 percent of healthy embryos are discarded as abnormal and only 1.5 percent are implanted with undetected genetic defects because of mosaicism. To find out how big of a problem mosaicism is, the researchers developed a mathematical model using data from UF's IVF program and other programs to...

Picking particles faster than one at a time

...rticle protrudes into the box, it is automatically discarded and replaced with a pattern textured like the rest of the background. At this end stage of the procedure -- although not at the beginning -- it may be advantageous to use templates (which include shape information about the particle) to refine identi...

Microbes convert 'Styrofoam? into biodegradable plastic

...ocess might also be used to convert other types of discarded plastics into PHA, according to O’Connor. PHA has numerous uses in medicine and can be used to make plastic kitchenware, packaging film and other disposable items. The biodegradable plastic is resistant to hot liquids, greases and oils, and can have...

Ocean virus identified in human blood samples

...upon a liver enzyme test, and whose blood had been discarded as a result, 21 percent had antibodies to Vesivirus. In blood samples from persons who had been diagnosed with clinical hepatitis, 29 percent had antibodies to Vesivirus. In persons who previously had transfusions or dialysis, and who then develo...

UF scientists trace origin of shark's electric sense

...pect as human ancestors emerged from the sea, they discarded their lateral lines as well as their ability to sense electrical fields. "Our fishy ancestors had the anatomy for it," said James Albert, aformer UF biologist who is now at the University of Louisiana. "You can imagine how valuable this system would...

Parallel evolution: Proteins do it, too

...lobines, the original, less efficient, gene is not discarded after duplication. But why, Zhang wondered. "The guess is that the old copy is still doing something important," he said. "RNASE1 has another function, which is to degrade double-stranded RNA. Double-stranded RNA is not normally found in food, but ...

Where we change our mind

This is an intuitive way of making estimations that are appropriate for many real-world behaviors, adopted also by a wide variety of intelligent machines.?" they wrote.

Embryo tests give parents the choice

...lthy embryos are implanted in the womb; others are discarded or frozen. The survey, which covered 186 out of 415 fertility clinics in the US, found that around two-thirds of PGD procedures were performed to identify embryos at risk of birth defects or being miscarried. However, the survey also revealed that a...

U-M researchers use nanoparticles to target brain cancer

...to re-examine previously developed drugs that were discarded because they caused too many dangerous side effects in patients. By combining the drug with a contrast agent, researchers were able using imaging techniques to determine whether the drug actually got to the tumor. This technique could have potenti...
