Carbon nanotubes may change the way doctors treat broken bones

Scientists have shown for the first time that carbon nanotubes make an ideal scaffold for the growth of bone tissue. The new technique could change the way doctors treat broken bones, allowing them to simply inject a solution of nanotubes into a fracture to promote healing.

Findings shed light on the underlying mechanisms that cause hypertension

An enzyme known to cause hypertension increases blood pressure by activating tiny pores, or channels, in kidney cells that allow increased levels of sodium to be reabsorbed into the blood, researchers at UT Southwestern Medical Center have found.

A new method for manipulating macromolecules

The technique uses double-stranded DNA to direct the behavior of other molecules. In previous DNA nanotechnology efforts, duplex DNA has been used as a static lattice to construct geometrical objects in three dimensions.

Studies show Alzheimer's prevented by drinking juice daily and having the occasional alcoholic drink

At a conference in the U.S. on Alzheimer's disease on June 19, researchers said that they think brain scans and simple blood tests may offer the best ways to predict who has the highest risk of Alzheimer's disease.

New device has the potential to significantly reduce sequencing of the human genome

The sequencing of the human genome was only the beginning of a much more complex task – deciphering the secrets of cellular chemistry and the mechanisms of disease. While the genome serves as a blueprint to understanding the body, proteins represent the materials that carry out these plans.

World first air purification technology for H5N1 Avian Influenza

Sharp Corporation has demonstrated that Plasmacluster Ions reduce activity of the highly fatal and highly pathogenic airborne H5N1 avian influenza ("bird flu") virus by 99%.

Protein TRPA1 essential for hearing also vital for pain perception

The same protein that "translates" sound into nerve signals to the brain and enables individuals to hear is also required for pain perception, researchers from Northwestern University Feinberg School of Medicine have found.

Sensor warns of gastrointestinal problems

Dutch researcher Sebastiaan Herber has developed a sensor which can detect poor blood circulation in the stomach. A high level of carbon dioxide in the stomach is a characteristic of this so-called gastrointestinal ischaemia. By measuring this concentration the sensor can indicate how good or bad the circulation in the stomach wall is.

New laser technology for more precise cancer treatments

Tom Cowan’s team is thinking smaller, but with big impact. Particle accelerators are a key research tool in a high energy physicist’s arsenal, but they take up a lot of space - miles and miles of it. But at the University of Nevada, Reno, smaller is better.

Researchers zero in on sleep gene

Zeroing in on the core cellular mechanisms of sleep, researchers at University of Wisconsin Medical School have identified for the first time a single gene mutation that has a powerful effect on the amount of time fruit flies sleep.

Isotopes for society

The nucleus of an atom contains protons and neutrons. However, some atoms of the same chemical element can have varying numbers of neutrons, giving so-called isotopes of that element.

New method for the study of ion channel gating kinetics

An ion channel is a protein pore that lets ions (charged atoms such as calcium) pass through a cell's membrane. The method fits data to a new class of models, called manifest interconductance rank (MIR) models, which will give researchers a better understanding of the mechanisms by which ion channels open and close.

Process called sumoylation regulates key ion channel

Researchers at the University of Chicago have found that a recently discovered biological process known as sumoylation -- until now thought to be active only in the nucleus -- also occurs near the cell's surface where it regulates at least one and possibly many kinds of proteins, providing a novel target for the development of new drugs.

An exceptionally effective lead-detection protein

Scientists from the U.S. Department of Energy’s Brookhaven National Laboratory and the University of Chicago have discovered that a member of a well-known protein family is better at detecting lead than any other known substance.

New ion channel drug targets to emerge in pharmaceutical discovery

The identification and structural determination of channel proteins, and their validation as therapeutic targets using high throughput cell based and multiplexed screening technologies, have furnished an increase role for ion channel targets in the drug discovery and development pipelines in the pharmaceutical and biotechnology industries.

Study of Anoxia could yield better anesthetics, stroke/heart attack recovery

For a human, mere minutes without oxygen (called anoxia) resulting from cardiac arrest, cerebral stroke or being trapped under water can lead to profound tissue damage and even death. However a Western painted turtle can survive anoxia for months without apparent tissue damage. Why, and how?

Statins, other cholesterol-depleting agents, may disrupt hypertension from developing

Cholesterol-lowering agents, such as the widely-prescribed statin drugs, and cholesterol-blocking agents may prove to be “novel therapeutic agents to modify cellular calcium that contributes to the development of pulmonary hypertension,” according Hemal H. Patel who lead a multidisciplinary team of researchers at the University of California, San Diego (UCSD).

Garlic protects against severe chronic pulmonary hypertension

Small daily doses of allicin, the active metabolic in garlic, proved effective in preventing a severe form of pulmonary hypertension in rats

Researchers have identified the proteins that allow specific brain cells to "change channels"

Johns Hopkins researchers have identified the proteins that allow specific brain cells to "change channels," a rare ability that tweaks what can come into the cell. The findings, described in the March 24 issue of Neuron, might let researchers harness the process, perhaps one day using it to protect cells that die in Lou Gehrig's disease.

Naturally occurring antifungal agent in saliva kills oral pathogen responsible for most HIV-related oral infections

Oral biologists at the University at Buffalo have shown for the first time how histatin, the naturally occurring antifungal agent in saliva, kills the oral pathogen Candida albicans, the fungus responsible for most HIV-related oral infections.
