Bioartificial kidney under study at MCG

...ney failure adds billions of kidney cells that can perform many of these important kidney functions. Human pr...re. Kidneys require a lot of oxygen and energy to perform their endless task, which makes them easy targets in the ICU, Dr. Szerlip explains. As examples, kid...

Novel technology detects human DNA mutations

...ventions ?two widespread methods currently used to perform such analyses. "Nanosphere's new SNP analysis methodology for whole genomic human DNA is a powerful example of the versatility of our proprietary ClearReadTM nanoparticle technology," said William Moffitt, Nanosphere's President and CEO. "This stud...

“Nano-scissors?laser shows precise surgical capability

...at precision : Anultra-short pulse laser that can perform extremely precise surgery ontiny roundworms may be the key to understanding nerve regeneration andis an important step toward treatment of human neurological disease,according to research published in the Dec. 16 issue of Nature. Dr.Adela Ben-Yakar,...

Gene therapy converts dead bone graft to new, living tissue

...like any other tissue in the human body, can still perform one of its functions, structural support, even if all its cells are completely dead. A serious problem arises, however, when the bone wears over time. "Everyday activities cause microscopic fractures in our bones," explains Schwarz. "Those fractures...

Poplar trees redirect resources in response to simulated attack

...to environmental challenges -- or their ability to perform useful tasks such as carbon sequestration, phytoremediation, or the production of bio-fuels -- could also use functional imaging to help track their progress. In the New Phytologist study, the scientists asked how plants deal with an external stress...

New Study from Affymetrix Laboratories Points to Changing View of How Genome Works

...rays to give the research community the ability to perform these types of unbiased studies as well. By focusing research beyond the parts of the genome that have been traditionally studied, scientists hope to discover new drug targets, new biomarkers, and a better understanding of disease mechanism. This pr...

New RNA polymerase discovered in plants

...eukaryotes, the RNA polymerases Pol I, II, and III perform the same distinct , though separate, functions in different species. But then along came Pol IV. Pikaard first noticed the evidence for a fourth polymerase when analyzing gene sequences after Arabidopsis thaliana , the "laboratory rat" of the plant ...

Affymetrix and the Karolinska Institutet Announce Translational Medicine Strategic Alliance

...t of various diseases. The agreement enables us to perform these studies at an acceptable cost and we will al...will allow researchers at Karolinska Institutet to perform high-density genome scans and genome-wide association studies on the genetics of complex diseases. ...

Carnegie Mellon scientists develop tool that uses MRI to visualize gene expression in living animals

... investigators don't need to sacrifice animals and perform laborious and costly analysis. To trigger living cells into producing their own contrast agent, Ahrens gave them a gene that produces a form of ferritin, a protein that normally stores iron in a non-toxic form. This metalloprotein acts like a nano-m...

Implanted Devices Detect High-Risk Heart Failure Patients

..., with CRT-Ds being the latest technology. CRT-Ds perform two main functions. First, the devices electrically stimulate both sides of the heart in coordinated fashion, which optimizes the contractability of already weakened heart muscle. Second, the defibrillator "shocks" the heart back into normal rhythm w...

Sequencing of marine bacterium will help study of cell communication

... Having access to the genetic sequence in order to perform this chore gave Stevens and Faini early access to specific information about the genes of the bacterium she has been studying for several years. Many different bacteria use quorum sensing. Stevens explains that cells release autoinducer molecules. T...

Self-assembled nano-sized probes allow Penn researchers to see tumors through flesh and skin

...in the body simultaneously. Emissive polymersomes perform much like in vivo imaging systems that use semiconductor-based "quantum dots." These quantum dots, however, are hard matter, which could collect within the circulatory system, potentially causing a stroke. According to the Penn researchers, brightly ...

Expression Project for Oncology (expO) completes first phase of standardized gene expression analyses

...ocure tissue samples under standard conditions and perform gene expression analyses on a clinically annotated set of deidentified tumor samples updated with clinical outcomes and release all data into the public domain without intellectual property restriction. "This publicly accessible gene expression clin...

Supercomputer Dedicated To Bioengineering, Computational Biology Installed

...ager Doug Shaw, and Bioengineering chair Shu Chien perform a ceremonial ribbon cutting at the dedication of UCSD's new cluster computer. "No single computational model spans all these biological scales, but this powerful new cluster will enable us to integrate models over many of these scales, which will ma...

Programmable cells: Engineer turns bacteria into living computers

...circuits. The cells, for example, could be made to perform basic mathematical logic and produce crisp, reliable readouts that are more commonly associated with silicon chips than biological organisms. The new paper applies similar techniques to a large population of cells. "Here we're showing an integrated ...

Wisconsin researchers identify sleep gene

...eeping flies, named minisleep (mns), were found to perform normally and did not appear to be impaired by sleep deprivation. The mns flies, however, did have shorter life spans. Following the testing, the researchers noticed shaking in the flies' legs as the insects recovered from anesthesia. The observation...

Robot-based system developed at Carnegie Mellon detects life in Chile's Atacama desert

...er followed a transect and stopped occasionally to perform detailed surface inspection, effectively creating a "macroscopic quilt" of geologic and biological data in selected 10 by 10 centimeter panels. After the rover departed a region, the ground truth science team collected samples the rover had examined....

...uiring reactions within the mitosome but might not perform other functions. The work suggests that the Entamoeba mitosome may represent the simplest mitochondrion yet described, and thus it provides a model system for probing which mitochondrial functions are truly essential for eukaryotic cells. ...

Stem cells from brain transformed to produce insulin at Stanford

...Kim's next step was to find out if the cells could perform the same feat in a mouse. The group transplanted the cells into a cavity in the kidney where other types of insulin-producing cells have been found to survive. When the blood sugar went up in these mice, the cells once again released insulin. After f...
