New smart anti-microbial approach to preventing tooth decay

Preventing cavities could one day involve the dental equivalent of a military surgical strike. A team of researchers supported by the National Institute of Dental and Craniofacial Research report they have created a new smart anti-microbial treatment that can be chemically programmed in the laboratory to seek out and kill a specific cavity-causing species of bacteria, leaving the good bacteria untouched.

UT Southwestern looks at promising new medication that reduces the severity and frequency of asthma attacks

UT Southwestern Medical Center is one of a handful of top research institutions evaluating a promising new medication researchers hope can reduce the severity and frequency of asthma attacks in inner-city children, a population known to have a high prevalence of severe asthma.

Helicobacter pylori increases risk of lower stomach cancer, decreases risk of upper

The bacteria Helicobacter pylori substantially increase the risk of cancer in the lower stomach, but it may decrease the risk of cancer near the junction between the esophagus and the stomach, according to a study in the October 19 Journal of the National Cancer Institute.

Vaccine that protects mice against 1918 influenza virus developed

Federal scientists have developed a vaccine that protects mice against the killer 1918 influenza virus. They also have created a technique for identifying antibodies that neutralize this virus, a tool that could help contain future pandemic flu strains.

Researchers identifiy how immune system contributes to nerve fiber damage caused by multiple sclerosis

Researchers have identified how the body's own immune system contributes to the nerve fiber damage caused by multiple sclerosis, a finding that can potentially aid earlier diagnosis and improved treatment for this chronic disease.

Lab-on-a-chip technology for determination of protein isoform profiles

A new microfluidics device that uses immobilized antibodies and carbon nanostrings as detection agents can identify slight variations in protein composition, known as protein isoforms, that could indicate the presence of cancer.

FDA approves FluLaval

The U.S. Food and Drug Administration (FDA) today approved FluLaval, an influenza vaccine to immunize people 18 years of age and older against the disease caused by strains of influenza virus judged likely to cause seasonal flu in the Northern Hemisphere in 2006-2007.

New bird flu vaccine promises to offer cross-protection

Early clinical trials of a new bird flu vaccine have produced promising results and a phase 3 trial of the cell-based H5N1 flu vaccine is expected to take place early next year.

Multispectral imaging of clinically relevant cellular targets in tonsil and lymphoid tissue using semiconductor quantum dots

When pathologists examine tissue samples in order to diagnose cancer of the lymphatic system, they examine the relative amounts of a group of proteins known as Cluster of Differentiation markers.

Carbon nanotube amplification strategies for highly sensitive immunodetection of cancer biomarkers

In an attempt to increase the sensitivity of cancer biomarker detection and to decrease the need for large samples from which to detect those molecules, a multi-institutional research team has shown that a "forest" of single-walled carbon nanotubes can be used to detect lower levels of the prostate specific antigen (PSA) than is possible using the current commercial assay.

Smokers may be at greater risk of HIV infection than non-smokers

Cigarette smoking has already been linked to a higher than normal chance of contracting other infections generally, including those that have been sexually transmitted.

Cell detachment model for an antibody-based microfluidic cancer screening system

In the quest to detect more types of cancers at ever earlier stages, researchers have been stymied by a lack of cell surface markers that distinguish in a clear-cut manner between healthy and malignant cells.

Live H5N1 avian flu vaccines show promise

When tested in mice and ferrets, experimental vaccines based on live, weakened versions of different strains of the H5N1 avian influenza virus were well-tolerated and protected the animals from a deadly infection with naturally occurring H5N1 flu viruses.

New screening method shows how nanoparticles interact with human cells

Scientists at the Brookhaven National Laboratory have developed a screening method to examine how newly made nanoparticles interact with human cells following exposure for various times and doses. Using this new method, the investigators have been able to visualize how human cells interact with some specific types of carbon nanoparticles.
