A study using PET imaging to compare nicotine accumulation in smokers found that nicotine washed out of the addicted smoker’s lungs and into their blood less efficiently and the study could help provide a treatment program for cigarette smokers who are trying to quit, according to a research scheduled to appear online in the early edition of Proceedings of the National Academy of Sciences during the week of March 8.
Researchers have used gold nanoparticles as orientation sensors by combining their plasmonic properties with polarization imaging techniques and tracking them using photothermal imaging, according to an article published online Feb. 1 in Proceedings of the National Academy of Sciences.
Franz Pfeiffer, PhD, chair of the biomedical physics group at Technical University Munich and colleagues have reported progress in their “lensless” x-ray microscopy--an approach to imaging biological cells-they introduced last year. The results of their most recent research were published in the early edition of the Dec. 7-11 Proceedings of the National Academy of Sciences.
The American Medical Isotopes Production Act (HR 3276) was approved by the U.S. House of Representatives’ Energy and Commerce Committee on Oct. 21. The new legislation will help to fund projects for producing the medical isotope molybdenum-99 within the U.S., in order to ensure a consistent supply for American patients.
Hyperpolarized xenon signal amplification by gas extraction (Hyper-SAGE) is a promising tool for enhancing the sensitivity of nuclear MR spectra and MRI, according to research published in the September online edition of Proceedings of the National Academy of Sciences.
Researchers have found that the atomic force microscope, a tool widely used in nanoscale imaging, works differently in liquid environments, it was reported online in last week's Proceeedings of the National Academy of Sciences.
The cognitive processes involved with honesty suggest that truthfulness depends more on absence of temptation than active resistance to temptation, according to a study to be published online this month in the Proceedings of the National Academy of Sciences.
Scientists at Howard Hughes Medical Institute's Janelia Farm Research Campus in Ashburn, Va., have developed interferometric photoactivated localization microscopy (iPALM), which allows them to create 3D images of structures inside cells at high resolution with an optical microscope, according to research published online before print Feb. 6 in the Proceedings of the National Academy of Sciences.
The U.S. Department of Energy has selected Michigan State University in East Lansing, Mich., to design and establish the Facility for Rare Isotope Beams, a research facility to advance understanding of nuclear isotopes and the evolution of the cosmos.

Surgery with molecular fluorescence imaging using a dual fluorescent plus a magnetic marker decreases residual cancer, improves survival and MRI-guided clinical staging, according to two studies published in the March issue of Proceedings of the National Academy of Sciences.
Researchers at Massachusetts Institute of Technology and Harvard Medical School have built targeted nanoparticles that can cling to artery walls and slowly release medicine, which could be an alternative to drug-eluting stents in some patients with cardiovascular disease, according to research published in the Jan. 18 issue of the Proceedings of the National Academy of Sciences.
Human embryonic stem cells could be used to help restore cognitive abilities in patients after radiation for brain tumors, according to study appearing online Nov. 9 in the Proceedings of the National Academy of Sciences.
FDG-PET is a highly accurate way to distinguish between neurofibromas and sarcoma, according to a study from UCLA’s Jonsson Comprehensive Cancer Center that was published online this week in the Proceedings of the National Academy of Sciences.
Dennis O’Leary, MD, former Joint Comission president, has joined real-time location system developer Awarepoint as its chief strategy officer.
Reps. Edward J. Markey, D-Mass., Chairman of the House Energy and Commerce Committee Subcommittee on Energy and the Environment, and Fred Upton, R-Mich., the Ranking Member of the Subcommittee, have introduced the American Medical Isotopes Production Act, which seeks to ensure that a reliable supply of critical medical isotopes are produced in the United States.
President Barack Obama is planning to nominate Francis S. Collins, MD, PhD, as director of the National Institutes of Health (NIH) at the Department of Health and Human Services.
Eliminating the highly enriched uranium process (HEU)—the primary source of medical isotopes in the United States—would be technically and economically feasible, however, the conversion to an alternative source will be years away, is likely to be more costly than the report estimates, and will not alleviate the current ongoing shortages, according to a report released Jan. 14 by the National Academy of Sciences (NAS).

The use of health IT to reduce rehospitalizations will be welcome but also disruptive, said Stephen Jencks, an independent consultant in healthcare safety during a Feb. 24 webinar on the potential use of health IT to mitigate rehospitalizations, sponsored by the Agency for Healthcare Research and Quality (AHRQ).
During the Health IT Standards Committee meeting on Feb. 24 in Washington, D.C., the Clinical Operations Workgroup sought to gather comments on proposed recommendations on implementation specifications for content exchange, vocabulary and code set standards for the Interim Final Rule of meaningful use.
In 2006, the Center for Devices and Radiological Health (CDRH), a branch of the FDA, began examining the number of medical device reports they received. Over the past two years, the number of submitted reports has increased, sparking a demand for the CDRH to make a move to electronic reporting.
A new hospital breaking ground usually isn’t breaking news. But the vision of patient care at one new facility, tentatively named Palomar Medical Center West (PMC West), is currently illegal under California state law.
