Antivirals effectively curb influenza virus

...al trials, conducted from 2000 to 2004, which were designed to estimate the effect of post-exposure antiviral treatment on preventing influenza within households. Two of the trials were conducted with zanamivir and two with oseltamivir, permitting comparisons to be made between the two. The trials covered a ...

Sunshine pill for prostate cancer in 2009

A tablet designed to emulate the healing power of the sun could be available for the treatment of advanced prostate cancer as early as 2009. But it remains to be seen whether the drug will be the revolution in prostate cancer care that its makers claim. The drug, As...

Molecular signature may identify cisplatin-sensitive breast tumors

...at sensitivity was unknown. The current study was designed to answer that question and to investigate the mechanism underlying cisplatin sensitivity. The research team focused on the function of p63, a protein that plays a role in normal breast development and is related to the common tumor suppressor p5...

New cigarette designs don't offer lower predicted cancer risks

...e translational research of projects of Dr. Pankow designed to biologically confirm his epidemiological studies." Pamela Clark, Ph.D., senior research scientist at Battelle Centers for Public Health Research and Evaluation in Baltimore, said Pankow's study "has profound implications for tobacco product reg...

UCLA scientists design masks to hide genetic mutations from cell

...logy made by Gene Tools of Oregon, the researchers designed a custom mask to camouflage each abnormal splice. The technique prevents the cell from seeing the genetic defects and restores splicing to the correct location in the gene. IMPACT: The laboratory findings suggest a powerful new approach for tre...

Termites get the vibe on what tastes good

The results are published in the Journal of the Roya...

Re-analysis of cigarettes confirms tobacco companies increased addictive nicotine 11 percent

...Cigarettes are finely-tuned drug delivery devices, designed to perpetuate a tobacco pandemic," said former Commissioner Koh. "Yet precise information about these products remains shrouded in secrecy, hidden from the public. Policy actions today requiring the tobacco industry to disclose critical information a...

NIH announces phase III clinical trial of creatine for Parkinson's disease

The study is designed to include a broad range of people, with special efforts to recruit a diverse population that is similar to the makeup of the population with PD in the United States. The investigators will measure disease progression using standard rating scales ...

A steady, high-fat diet is bad, but the news gets worse

They performed a mathematical test designed to be stressful, completed a public speaking exercise about something emotionally provocative, held an arm in ice water, and had a blood pressure cuff inflated around an arm, which gradually causes a dull ache. "Regardless of the task, we rec...

Making mice with enhanced color vision

...um wavelengths. In the study, the researchers designed a "knock-in" mouse that has one copy of its medium wavelength receptor replaced with the human long wavelength receptor, so both were expressed in the retina. The human receptors were biologically functional in the mice, but the real question was whe...

Pacific Rim researchers to collaborate on distributed bioinformatics analysis of avian flu

...(The iGAP suite of bioinformatics applications are designed specifically for protein structural homology recognition and functional annotation.) The San Diego-based researchers will also develop a robust production environment for routine computational analysis, using PRAGMA member-developed tools, including ...

Lead-'scrubbing' drug may also improve muscle function in lead-exposed children

Tests were designed to eliminate or challenge factors that help maintain postural balance, such as eyesight and visual context. “Our statistical analysis revealed that subjects who received succimer therapy showed a significant improvement in balance and movement com...

Microfluidic chip helps solve cellular mating puzzle

...ess." Yeast cells mate by sending out pheromone designed to catch the attention of nearby cells of the opposite mating type. When a prospective partner picks up this "scent," it alters its shape and sends a projection toward the source of the pheromone, leading to a cellular merger. This mating process is ...

Engineering the heart piece by piece

...g, durable and shaped like the native tissue it is designed to replace, another major challenge remains: which type of cells to use. Or more clearly, which types of cells to use ?because heart muscle tissue is made up of several types of cells. Human heart cells are hard to come by, and “adult?stem cells have...

Fish can determine their social rank by observation alone, study finds

The research team focused on a molecule called CCR2, a receptor on the surface of microglia and other immune cells...

Protein therapy may reduce infarct size in heart attack patients

...rdiac outcomes through six months. This trial was designed as an exploratory study to assess the potential impact of KAI-9803 in this “first-in-human?study. Results indicate that KAI-9803 may be associated with less myocardial necrosis with lower CK-MB AUC values at all dose levels. Furthermore, improved ...
