Early schizophrenia symptoms include unusually high CA1 subfield activity

In the first functional magnetic resonance imaging (fMRI) study of its kind, neurologists and psychiatrists at Columbia University have identified an area of the brain involved in the earliest stages of schizophrenia and related psychotic disorders.

Iterative in situ click chemistry creates antibody-like protein-capture agents

Chemists at the California Institute of Technology (Caltech) and The Scripps Research Institute (SRI) have developed an innovative technique to create cheap but highly stable chemicals that have the potential to take the place of the antibodies used in many standard medical diagnostic tests. James R. Heath, Ph.D., principal investigator of the Nanosystems Biology Cancer Center at Caltech, one of eight Centers of Cancer Nanotechnology Excellence, and K. Barry Sharpless, Ph.D., SRI, and their colleagues describe the new technique in the journal Angewandte Chemie International Edition.

Specific targeting of brain tumors with an optical/magnetic resonance imaging nanoprobe across the blood-brain barrier

Earlier this year, researchers at the University of Washington reported that they had developed a toxin-nanoparticle combination that inhibits brain cancer invasion when added to tumor cells growing in culture.

Nanoparticle-delivered suicide gene therapy effectively reduces ovarian tumor burden in mice

Nanoparticle delivery of diphtheria toxin-encoding DNA that expresses selectively in ovarian cancer cells reduced the burden of ovarian tumors in mice, and researchers expect that this therapy could be tested in humans with advanced ovarian cancer within 18 to 24 months, according to a report in Cancer Research. If additional tests are successful, these finding could lead to a new treatment for ovarian cancer, which now causes more than 15,000 deaths each year in the United States. Because it is usually diagnosed at a relatively late stage, ovarian cancer is one of the most deadly forms of the disease.

Rapid detection and profiling of cancer cells in fine-needle aspirates

Using a new type of paramagnetic nanoparticle and a nuclear magnetic resonance (NMR) system built into a microfluidic device, a team of investigators at the Massachusetts General Hospital and Harvard Medical School has created an assay system capable of detecting as few as two cancer cells in 1 microliter of biological fluid. In addition, the new assay requires little sample processing and produces results in less than 15 minutes.

Molecularly targeted nanocarriers deliver the cytolytic peptide melittin specifically to tumor cells in mice, reducing tumor growth

When bees sting, they pump into their victims a peptide toxin called melittin that destroys cell membranes. Now, by encapsulating this extremely potent molecule within a nanoparticle, researchers at the Washington University School of Medicine in St. Louis have created a potential new type of anticancer therapy with the potential to target a wide range of tumors. This work was reported in the Journal of Clinical Investigation.

CLU and PICALM genes associated with Alzheimer's disease

British scientists have discovered two new genes associated with Alzheimer's disease, while French colleagues uncovered a third. The results, from the largest ever Alzheimer's genome-wide association study (GWAS) involving 16,000 individuals, are published in Nature Genetics. They are the first new genes found to be associated with the common form of Alzheimer's disease since 1993.
