WASHINGTON — A U.S. Environmental Protection Agency draft assessment of the potential health effects associated with formaldehyde exposure needs substantial revision, says a new report from the National Research Council, which recommends improvements for EPA's final assessment. The report finds that EPA supports its conclusions that formaldehyde can cause irritation to the eyes, nose, and throat; lesions in the respiratory tract; and genetic mutations at high concentrations.

Unlike the situation in other caves, damage caused by tourists at the Águila cave in Ávila, Spain is "imperceptible", despite it receiving tens of thousands of visitors each year. This is the main conclusion of an international research study headed by the University of Alcalá (UAH), which measured heat variations in the cave.
Could adult children's strategies for coping with pain come from watching their parents react to and deal with pain? According to Suzyen Kraljevic, from the University Hospital Split in Croatia, and colleagues, a family may have a specific cognitive style of coping with pain. Their work, which looks at the relationship between how parents and their children respond to pain, is published online in Springer's International Journal of Behavioral Medicine.
Fatigue and sleep problems dramatically reduce the thinking and reasoning abilities of adults who survived childhood cancer, according to new research from the Childhood Cancer Survivor Study. Researchers hope the findings will lead to new strategies for improved neurocognitive functioning in this growing population. The work was led by St. Jude Children's Research Hospital investigators.
Jerusalem, April 11, 2011 – Researchers at the Hebrew University of Jerusalem have discovered a previously unknown mechanism whereby tumor cells invade normal tissues, spreading cancer through various organs.
(Boston) – Researchers from Boston University School of Medicine (BUSM) have concluded that the anatomy of the pelvis following robotic-assisted radical prostatectomy
(RARP) is considerably different when compared to the anatomy of the pelvis following an open prostatectomy (OP). These findings, which are the first to ever compare pelvic anatomy following RARP and OP surgery, may have implications for patients requiring post-operative radiation. The study currently appears on-line in Practical Radiation Oncology.
Targeted photodynamic therapy can completely eradicate some models of cancer, according to the latest research by UK and Swiss scientists, published in the current issue of the British Journal of Cancer.
The team – including researchers from the University of Hull and ETH Zurich – linked light-sensitive molecules with antibodies that target tumour blood vessels. When irradiated with light, the molecules create particles known as reactive oxygen species, which in high numbers cause irreparable damage to cells.
The Internet has no borders, no universal legislation, and although highly social and distributed is not represented by cooperation across the globe. Given those characteristics how might nations make their plans for counter terrorism in cyberspace as active online as they are in the everyday world? A collaboration between researchers in the US and Iran hoped to address that issue and its findings are published this month in the International Journal of Internet Technology and Secured Transactions.
WASHINGTON -- Scientists at the Naval Research Laboratory Center for Bio-Molecular Science and Engineering have developed a method to detect the presence of viruses in cells and to study their growth. Targeting a virus that has ribonucleic acid (RNA) as its genetic makeup, the new technique referred to as locked nucleic acid (LNA) flow cytometry-fluorescence in situ hybridization (flow-FISH), involves the binding of an LNA probe to viral RNA.
MEDFORD/SOMERVILLE, Mass. -- For years, researchers in genome stability have observed that several neurodegenerative diseases—including Huntington's disease—are associated with cell-killing proteins that are created during expansion of a CAG/CTG trinucleotide repeat.
Each year in the U.S., approximately 40,000 babies are born with a heart defect. Without the proper diagnosis and treatment, many of these babies would die before their first birthday, according to Dr. Scott Klewer, a cardiologist at the UA's College of Medicine.
"We still don't know much about the causes of many of these defects. Some have been linked to certain genes but the picture is still sketchy," he says. "At this point, we can't predict how children will respond to current methods, but if we had genetic indicators we could use them to personalize treatments."
Virtually all processes in the human body rely on a unique class of proteins known as enzymes. To study them, scientists want to attach these molecules to surfaces and hold them fast, but this can often be a tricky undertaking.
Now Jinglin Fu and his colleagues at the Biodesign Institute at Arizona State University have developed a superior method for immobilizing enzymes on surfaces, deftly controlling their orientation, improving their efficiency and rendering them more stable. The group's results appear in today's advanced online issue of PLoS ONE.
Washington, D.C., April 11, 2011 – In a first-of-its-kind study with nuts, randomized controlled-feeding research conducted by the Agricultural Research Service (ARS) of the United States Department of Agriculture (USDA) found that fat in pistachios may not be completely absorbed by the body. The findings indicate that pistachios may actually contain fewer calories per serving than originally thought – further validating pistachios as one of the lowest calorie nuts with 160 calories per 30 gram serving (approximately 1 ounce).
WASHINGTON, D.C… April 11, 2011 … Researchers from Canada and the United States today told attendees of the Experimental Biology 2011 Scientific Meeting that they have uncovered a possible means of enabling women to favorably influence whether the estrogens in their bodies take a "beneficial path" or a "disease-potential" path.
Children with inborn errors of metabolism received vaccines on the same immunization schedule as did healthy infants, according to Kaiser Permanente Vaccine Study Center scientists who examined the Kaiser Permanente Northern California population. In addition, immunization was not associated with significant increases in emergency room visits or hospitalizations during the month following vaccination, according to Nicola Klein, MD, PhD, lead author of the study and co-director of the Kaiser Permanente Vaccine Study Center.
