Lab animal diet can foster inaccurate results
Laboratory Equipment    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The widespread practice of allowing laboratory rats and mice to eat as much as they want may be affecting the outcome of experiments in which scientists use these "test-tubes-on-four-feet" to test new drugs and other substances for toxicity and other effects. That's the conclusion of a new analysis published in ACS' journal Chemical Research in Toxicology. More



Patient data 'mega-registry' could bolster clinical research
InformationWeek    Share    Share on FacebookTwitterShare on LinkedinE-mail article
If the Office of Management and Budget approves, the Agency for Healthcare Research and Quality will soon establish a "registry of patient registries" to aid researchers doing comparative effectiveness research. The registries referenced in RoPR would include those related to clinical trials and might also encompass patient registries created by healthcare systems and accountable care organizations. More

HIV treatment results improving — But maybe not as much as thought
TIME    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Nearly three-quarters of U.S. HIV patients now receive antiretroviral treatment and are keeping their viral loads in check, according to a large national study. The study shows dramatic improvements in therapy coverage over just the past decade — but not as large a gain as previously estimated, medical researchers say. More

Pathologists, researchers develop technology that predicts cancer relapse
Dark Daily    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Over the past decade, clinical laboratory tests that can predict the occurrence or recurrence of breast cancer have opened up a profitable market for the companies that developed these technologies. Now, new research may become the basis of a useful medical laboratory test that could be predictive of prostate cancer relapse. More



Super-resolution microscopy highlights bacterial biofilms
The Medical News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A multi-fluorescent labeling strategy combined with super-resolution light microscopy has allowed researchers to observe the development of a bacterial biofilm in real-time. The team watched the development of the Vibrio cholerae biofilm with "single-protein and single-polymer precision, revealing assembly principles and intermediates." More

Researchers use infant hair to study HIV drug exposure
Laboratory Equipment    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Researchers have used hair and blood samples from 3-month-old infants born to HIV-positive mothers to measure the uninfected babies' exposure — both in the womb and from breast-feeding — to antiretroviral medications their mothers were taking. More

Protein study brings muscle movement into sharper focus
R&D Magazine    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Muscle contraction and many other movement processes are controlled by the interplay between myosin and actin filaments. Two further proteins, tropomyosin and troponin, regulate how myosin binds to actin. While theoretical models have in fact described exactly how these muscle proteins interact, this interaction has never previously been observed in detail. More

Blood vessel-forming potential of stem cells from placenta, cord blood
Medical Express    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A study comparing whether endothelial colony-forming cells derived from human placenta or those derived from human umbilical cord blood are more proliferative and better for forming new blood vessels has found that ECFCs derived from human placenta are more vasculogenic. More

To test or not to test?
Journal of the American Academy of Physician Assistants    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Ordering tests is a critical part of physician assistant work. Tests help us diagnose and treat patients. We use procedures to further define diseases and ease our patients' symptoms. CT scans aid us in our search for brain tumors and bleeds. Colonoscopies assist us in our fight against cancer. Lab work is perhaps the most common type of test we order. Labs help us find and treat pathology. Lab ordering is quick and easy, especially with the advent of EMR. More

Leukemia mutations linked to aging, not cancer
Science 2.0    Share    Share on FacebookTwitterShare on LinkedinE-mail article
At the time of diagnosis, hundreds of mutations already exist in leukemia cells but new research has found they are a part of normal aging and are not related to cancer. Even in healthy people, stem cells in the blood routinely accumulate new mutations over the course of a person's lifetime. In many cases only two or three additional genetic changes are required to transform a normal blood cell already dotted with mutations into acute myeloid leukemia. More

Nanoscale scaffolds and stem cells show promise in cartilage repair
Medical Xpress    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Johns Hopkins tissue engineers have used tiny, artificial fiber scaffolds thousands of times smaller than a human hair to help coax stem cells into developing into cartilage, the shock-absorbing lining of elbows and knees that often wears thin from injury or age. While the findings are still years away from use in people, the researchers say the results hold promise for devising new techniques to help the millions who endure joint pain. More
