World's first head-to-head data on latest antihistamines has implications for hay fever management
First head-to-head data on the two latest antihistamines presented for the first time at the Annual Meeting of the British Society for Immunology (BSI) and the British Society for Allergy & Clinical Immunology (BSACI) today, indicates that Xyzal® (levocetirizine) is more effective than NeoClaritynTM(desloratadine) in treating subjects with seasonal allergic rhinitis (hay fever).

It may take a mouse to understand the behavior of 'jumping genes'
Up to a third of the human genome is due to the random maneuverings of retrotransposons.

Additive-free cigarettes may pack a more toxic tobacco punch
Despite perceptions that additive-free cigarettes and the hand-rolled cigarettes from India called bidis may provide a less-toxic smoke than conventional cigarettes, new research suggests the opposite may be true.

Climate change will affect carbon sequestration in oceans, scientists say
The direct injection of unwanted carbon dioxide deep into the ocean is one suggested strategy to help control rising atmospheric carbon dioxide levels and mitigate the effects of global warming.

Birth control pills associated with breast cancer risk in BRCA1 mutation carriers
Women who carry mutations in the BRCA1 breast cancer susceptibility gene and have a history of oral contraceptive use may have an increased risk of early-onset breast cancer, according to a large-scale study in the December 4 issue of the Journal of the National Cancer Institute.

CWRU researcher reveals differences in high-altitude living
New discoveries by Case Western Reserve University anthropologist Cynthia Beall continue to unravel the mystery of how humans have adapted to high altitude living.

Restoration of faulty blood vessel architecture by angiopoietin-1
Angiogenesis (growth of new blood vessels) requires complex signaling between multiple cell types and abnormalities in these pathways results in faulty vessels.

New first-aid method could prevent brain damage in patients exposed to carbon monoxide
A new first-aid method of treating carbon monoxide poisoning could prevent brain damage in patients by delivering more oxygen to the brain than the standard treatment, according to a study by physicians at the Toronto General Hospital, University Health Network (UHN).

UV radiation may not be a factor in amphibian declines
Two reports published in a leading science journal cast doubt on the importance of ultraviolet-b radiation (UV-B) as a factor driving amphibian population declines.

Other highlights of the December 4 JNCI
Other highlights include a study suggesting that COX-2 inhibitors can be used to develop other anticancer agents, a study showing that genetic polymorphisms may help identify strains of the Epstein-Barr virus associated with malignant disease, a study finding that an allele common among Chinese may explain the high rates of nasopharyngeal cancer in this population, and a study examining whether a mosquito-borne virus may be used as a vector to target tumors.

Alternative treatment for secretory diarrhea linked to the cystic fibrosis gene
In the December 2 issue of the Journal of Clinical Investigation, Alan Verkman and colleagues at the Cardiovascular Research Institute at the University of California, San Francisco, identified a compound called thiazolidinone, capable of inhibiting chloride ion secretion via chloride channels in cells lining the lung and intestine in mice.

Study finds seasonal differences affect Brahman bull sexual maturity
Fall-born Brahman bulls require more than a month longer to reach sexual maturity than Brahman bulls born in the spring, according to recent research by an internationally recognized authority on the reproductive physiology of Brahman cattle.

When more data can mean more fun
Tomorrow's spacecraft will be capable of generating more data than they can transmit to Earth.

Promising biomarker for melanoma is identified
NYU School of Medicine researchers have identified a potential biomolecular marker for melanoma, the most serious form of skin cancer.

Bush signs; ozone treatment for ballast water; wetland restoration template goes national
The following are Sea Grant legislative news: Pres. Bush signs Sea Grant reauthorization; ozone, biocide treatments aiming to control nuisance species from ballast water; and, Oregon wetland template going national.

Hopkins study finds combined PET-CT better at detecting ovarian cancer
Hopkins radiologists have found that a combination of positron emission tomography (PET) and computed tomography (CT) detects cancer spread better than PET alone.

Portion size matters: Given too much, we eat it
Almost nobody can stop eating at just one normal serving if there's extra food on their plate, Penn State researchers have shown, and this tendency coupled with the spread of megaportions may be contributing to the American obesity epidemic.

Scientists find new way to assess where cotton-killing pests develop
In a finding that could have broad implications for farmers' ability to stop pests from decimating cotton crops, scientists from North Carolina State University and agricultural research stations in the Cotton Belt have developed a new technique to determine where the larvae of certain agricultural pests develop.

Road testing technologies of the future
ESA is offering industry the opportunity to use a van fully equipped to demonstrate the next generation of advanced mobile multimedia equipment and applications.

Diabetic gene linked to heart disease
Using a simple blood test, researchers at the Technion-Israel Institute of Technology have identified a gene that determines which diabetes patients are at greater risk for developing heart disease.

OHSU researchers make key immune system discovery
Researchers at Oregon Health & Science University make a key discovery regarding the body's immune system.

UB engineer develops novel method for assembly of nanoparticles
A University at Buffalo engineer has developed a novel method for assembling nanoparticles into three-dimensional structures that one day may be used to produce new nanoscale tools and machines.

Bridge Medical experts speak at Atlanta pharmacy conference
Medication safety expert Susanne Larrabee, RPh will share her experiences in using barcode technology to protect patients from medication errors at the ASHP (American Society of Health-System Pharmacists) Midyear Clinical Meeting next week in Atlanta.

Researchers release baseline data from randomized colorectal cancer screening trial
A major trial is under way to determine the impact of single screening sigmoidoscopy on colorectal cancer incidence and mortality.
