GEN reports on nanotechology's impact on mass spectrometry

GEN reports on nanotechology's impact on mass spectrometry
2011-08-04
(Press-News.org) New Rochelle, NY, August 3, 2011—A move toward smaller and smaller sample sizes is leading to a new generation of mass spectrometry instrumentation, reports Genetic Engineering & Biotechnology News (GEN). From a specific application point of view, novel nanoflow separation methodologies are ramping up the speed and precision with which scientists are able to validate biomarkers, according to the August issue of GEN (www.genengnews.com/gen-articles/nanoliter-volumes-push-ms-to-new-lows/3741).

"Basing biomarker validation on more sophisticated mass spec tools could help increase the number of clinical applications for biomarkers," said John Sterling, Editor in Chief of GEN.

Proteome Sciences, for example, performs protein biomarker discovery, validation, and mass spec-based assay development and has introduced commercial assays for Alzheimer's disease. In collaboration with Thermo Fisher Scientific, the company has developed isobaric tagging technology in Tandem Mass Tags that allows users to assay up to six samples per run on the Thermo Orbitrap Velos mass spectrometry system.

Researchers at the University of North Carolina in Chapel Hill have developed an integrated microfluidic capillary electrophoresis-MS method using data-independent multiplexed fragmentation to perform high-throughput proteomics. The technique could be applied to a bottom-up proteomic approach and for characterization of protein-based biotherapeutics.

Also discussed in the GEN article is work on advanced mass spec techniques taking place at the University of Washington (Seattle) and Leiden University Medical Center in The Netherlands and at companies such as New Objective, Waters, OpAns, Analytical Scientific Instruments, Agilent Technologies, and Dionex.

Researchers develop and test new molecule as a delivery vehicle to image and kill brain tumors

2011-08-04
RICHMOND, Va. (Aug. 3, 2011) – A single compound with dual function – the ability to deliver a diagnostic and therapeutic agent – may one day be used to enhance the diagnosis, imaging and treatment of brain tumors, according to findings from Virginia Commonwealth University and Virginia Tech. Glioblastomas are the most common and aggressive brain tumor in humans, with a high rate of relapse. These tumor cells often extend beyond the well-defined tumor margins making it extremely difficult for clinicians and radiologists to visualize with current imaging techniques. Researchers ...

New study calls into question reliance on animal models in cardiovascular research

New study calls into question reliance on animal models in cardiovascular research
2011-08-04
Anyone who follows science has read enthusiastic stories about medical breakthroughs that include the standard disclaimer that the results were obtained in mice and might not carry over to humans. Much later, there might be reports that a drug has been abandoned because clinical trials turned up unforeseen side effects or responses in humans. Given the delay, most readers probably don't connect the initial success and the eventual failure. But Igor Efimov, PhD, a biomedical engineer at Washington University in St. Louis who studies the biophysical and physiological ...

Bellybutton microbiomes

2011-08-04
Public awareness about the role and interaction of microbes is essential for promoting human and environmental health, say scientists presenting research at the Ecological Society of America's (ESA) 96th Annual Meeting from August 7-12, 2011. Researchers shed light on the healthy microbes of the human body and other research on microbial and disease ecology to be presented at ESA's 2011 meeting in Austin, Texas. Bellybutton microbiomes Human skin is teeming with microbes—communities of bacteria, many of which are harmless, live alongside the more infamous microbes sometimes ...

Mold exposure during infancy increases asthma risk

2011-08-04
Infants who live in "moldy" homes are three times more likely to develop asthma by age 7—an age that children can be accurately diagnosed with the condition. Study results are published in the August issue of Annals of Allergy, Asthma & Immunology, the scientific journal of the American College of Allergy, Asthma and Immunology (ACAAI). "Early life exposure to mold seems to play a critical role in childhood asthma development," says Tiina Reponen, PhD, lead study author and University of Cincinnati (UC) professor of environmental health. "Genetic factors are also ...

US physicians spend nearly 4 times more on health insurance costs than Canadian counterparts

2011-08-04
ITHACA, N.Y. — U.S. physicians spend nearly $61,000 more than their Canadian counterparts each year on administrative expenses related to health insurance, according to a new study by researchers at Cornell University and the University of Toronto. The study, published in the August issue of the journal Health Affairs, found that per-physician costs in the U.S. averaged $82,975 annually, while Ontario-based physicians averaged $22,205 – primarily because Canada's single-payer health care system is simpler. Canadian physicians follow a single set of rules, but U.S. doctors ...

Group Health establishes major initiative to prevent opioid abuse and overdose

2011-08-04
SEATTLE—Fatal overdoses involving prescribed opioids tripled in the United States between 1999 and 2006, climbing to almost 14,000 deaths annually—more than cocaine and heroin overdoses combined. Hospitalizations and emergency room visits related to prescription opioid pain medicines such as oxycodone (brand name Oxycontin) and hydrocodone (Vicodin) also increased dramatically in the same period. Now a report in the August issue of Health Affairs describes a major initiative at Group Health to make opioid prescribing safer while improving care for patients with chronic ...

Compression stockings may reduce OSA in some patients

2011-08-04
Wearing compression stockings may be a simple low-tech way to improve obstructive sleep apnea in patients with chronic venous insufficiency, according to French researchers. "We found that in patients with chronic venous insufficiency, compression stockings reduced daytime fluid accumulation in the legs, which in turn reduced the amount of fluid flowing into the neck at night, thereby reducing the number of apneas and hypopnea by more than a third," said Stefania Redolfi, MD, of the University of Brescia in Italy, who led the research. CVI occurs when a patient's veins ...

2011-08-01
A scientist at the Gladstone Institutes has discovered a novel way to convert human skin cells into brain cells, advancing medicine and human health by offering new hope for regenerative medicine and personalized drug discovery and development. In a paper being published online today in the scientific journal Cell Stem Cell, Sheng Ding, PhD, reveals efficient and robust methods for transforming adult skin cells into neurons that are capable of transmitting brain signals, marking one of the first documented experiments for transforming an adult human's skin cells into ...

Researchers target, switch off serotonin-producing neurons in mice

2011-08-01
Boston, MA (July 28, 2011) — Researchers have developed a toolkit that enables them to turn off targeted cell populations while leaving others unaffected. Led by Susan Dymecki, a professor of genetics at Harvard Medical School, the group focused on serotonin-producing neurons, observing how mice behave in a normal environment when suddenly their serotonin neurons are turned down. While their findings affirm earlier studies, the researchers used a technique that is non-invasive and does not require anesthesia, surgeries, or knocking out a gene—each of which can cause ...
