New findings on snake venom toxin hold promise for developing heart disease, cancer therapies

Researchers seeking to learn more about stroke by studying how the body responds to toxins in snake venom are this week releasing new findings that they hope will aid in the development of therapies for heart disease and, surprisingly, cancer. The Japanese team is reporting in a Journal of Biological Chemistry "Paper of the Week" that they are optimistic that inhibiting a protein found on the surface of blood cells known as platelets may combat both irregular blood clotting and the spread of certain cancers throughout the body.

Researchers unveil mechanism of cholera bacteria to create cell energy

Researchers have found that an enzyme in the bacteria that causes cholera uses a previously unknown mechanism in providing the bacteria with energy. Because the enzyme is not found in most other organisms, including humans, the finding offers insights into how drugs might be created to kill the bacteria without harming humans.

New implantable sensor to continuously monitor tissue glucose

Bioengineers at the University of California, San Diego and GlySens Incorporated have developed an implantable glucose sensor and wireless telemetry system that continuously monitors tissue glucose and transmits the information to an external receiver. The paper, published in the July 28, 2010 issue of the journal Science Translational Medicine, describes the use of this glucose-sensing device as an implant in animals for over one year. After human clinical trials and FDA approval, the device may be useful to people with diabetes as an alternative to finger sticking and short-term, needle-like glucose sensors that have to be replaced every three to seven days.

Use of nanomaterials in construction poses potential environmental and health risks

Nanomaterials are poised for widespread use in the construction industry, where they can offer significant advantages for a variety of applications ranging from making more durable concrete to self-cleaning windows. But widespread use in building materials comes with potential environmental and health risks when those materials are thrown away. Those are the conclusions of a new study published by Rice University engineering researchers this month in ACS Nano.

Scientists unveil nanoparticle for photoacoustic imaging

Spotting a single cancerous cell that has broken free from a tumor and is traveling through the bloodstream to colonize a new organ might seem like finding a needle in a haystack. But a new imaging technique from the University of Washington is a first step toward making this possible.UW researchers have developed a multifunctional nanoparticle that eliminates the background noise, enabling a more precise form of medical imaging - essentially erasing the haystack, so the needle shines through. A successful demonstration with photoacoustic imaging was reported today (July 27) in the journal Nature Communications.

Discontinuing epoetin can normalize hemoglobin levels in hemodialysis patients

Discontinuing the anemia drug epoetin may be more effective than reducing the dose for normalizing potentially dangerous high hemoglobin levels in hemodialysis patients, according to a study appearing in an upcoming issue of the Clinical Journal of the American Society Nephrology. The results provide useful information about the balance required between administering epoetin and achieving target hemoglobin levels.

Super hemoglobin allows moles to grow underground

'Super hemoglobin' allows moles to thrive underground. Researchers writing in the open access journal BMC Evolutionary Biology have made the first identification of an adaptation in the blood of Eastern moles which allows more efficient transport of carbon dioxide, facilitating the moles' burrowing behavior.

Gene essential for respiration and survival at birth identified

How do mammals prepare themselves in utero for a radical modification to their respiration at the time of birth, when they move abruptly from an aquatic medium to air? CNRS researchers, working in collaboration with teams from the Universities of the Méditerranée, Paris-Sud 11 and Paul Cézanne have identified a gene in the mouse that is essential to respiration and consequently to survival at birth.

Replacing hydrogen with deuterium increases stability, shelf life of fluorescent probes: Research

By swapping out one specific hydrogen atom for an isotope twice as heavy, researchers have increased the shelf life and detection ability of fluorescent probes that are essential to studying a variety of inflammatory diseases, including cancer and atherosclerosis. The probes detect and measure reactive oxygen species, which play an important role in disease processes.
