Labour market trends may have impact on the mental health of young people

Mental health in young people worsens in line with trends in the labour market. Researchers writing in the open access journal BMC Public Health studied data from 1985 to 2002 and found that, across ten European countries, as the proportion of young people not in work increased, so did the proportion of 15-year-olds who reported mental health symptoms such as feeling low, difficulty sleeping or headaches.

Presence of virus linked with malignant human prostate cancer cells

In a finding with potentially major implications for identifying a viral cause of prostate cancer, researchers at the University of Utah and Columbia University medical schools have reported that a type of virus known to cause leukemia and sarcomas in animals has been found for the first time in malignant human prostate cancer cells.

Baucus reportedly proposing new insurance fee to pay for health reform

The New York Times reports that "In a last effort to give the Senate a bipartisan health care bill," Sen. Max Baucus, D-Mont., "the chairman of the Senate Finance Committee circulated a comprehensive proposal on Sunday to overhaul the health care system and proposed a new fee on insurance companies to help pay for coverage of the uninsured."

Insects can be used to test the efficiency of new drugs

Insects, such as some moths and fruit flies, react to microbial infection in the same way as mammals and so can be used to test the efficiency of new drugs, thereby reducing the need for animal testing. Dr Kevin Kavanagh from the National University of Ireland - Maynooth, presented his research findings at the Society for General Microbiology's meeting at Heriot Watt University, Edinburgh, today (8 September).

geneX combined with Mesenchymal stem cells for treating fracture

Professor James B. Richardson of the Robert Jones and Agnes Hunt Orthopaedic Hospital, Oswestry, UK has been carrying out pioneering work combining geneX with selected and culture expanded Mesenchymal stem cells to treat fracture non-unions.

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.

Nanotags pinpoint multiple cancer markers in live animals

Using nanoparticles designed specifically to produce a bright Raman spectroscopic signal, a team of investigators at the Center for Cancer Nanotechnology Excellence Focused on Therapy Response (Stanford University Center for Cancer Nanotechnology Excellence [CCNE]) has shown that it can simultaneously track as many as 10 different optical tags in a living animal.

Practitioners struggle to effectively manage child obesity

New research, led by Dr Katrina Turner from the University's Department of Community Based Medicine, has assessed primary care practitioners' views and experiences of treating childhood obesity.

Aptamer nanoflares for molecular detection in living cells

By combining a gold nanoparticle with a unique family of nucleic acids, researchers at Northwestern University have created a new type of intracellular reporting system that with a flash of light reveals the presence and quantity of a wide variety of biologically important molecules. These so-called nanoflares could provide cancer biologists with a highly sensitive method of tracking complex biochemical processes in real time without interfering with those processes.

Nanotubes destroy kidney tumors

By injecting multiwalled carbon nanotubes (MWCNTs) into tumors and heating them with a quick, 30-second zap of a laser, a multi-institutional team of researchers from the Wake Forest University School of Medicine (WFUSOM), Wake Forest University Center for Nanotechnology and Molecular Materials, Rice University, and Virginia Polytechnic Institute and State University has developed a new type of therapy that effectively kills kidney tumors in nearly 80% of treated mice. Researchers say that the findings, which were published in the Proceedings of the National Academy of Sciences of the United States of America, suggest a potential future cancer treatment for humans.

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.

Reversible cell-specific drug delivery with aptamer-functionalized liposomes

For cancer drug developers, finding an agent that kills tumor cells is only part of the equation. The drug also must spare healthy cells, and ideally its effects will be reversible to cut short any potentially dangerous side effects. Investigators from the University of Illinois at Urbana-Champaign report that they have assembled a new cancer drug delivery system that, in cell culture, achieves all of the above.

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.
