Earliest European Farmers Left Little Genetic Mark On Modern Europe

...tment strategies. The annual AIDS Epidemic Update reports on the latest developments in the global AIDS epidemic. With maps and regional estimates, the 2005 edition provides the most recent estimates on the epidemic’s scope and human toll, explores new trends in the epidemic’s evolution, and features a spec...

Study Unlocks Insects?Secret for Love in the Dark

...tain View, Calif., that includes 200,000 published reports on more than 8,000 human, rat and mouse genes and their genetic interactions. This tool enabled the group to uncover about 300 genes and several genetic pathways not previously known to be involved in inflammation. The Nature article is the second i...

Polymer gel can block toxic leakage problem in gene therapy

... targets during the first 10 minutes. Prompted by reports of animal deaths during past gene therapy trials with adenoviruses, this study provided the first direct research evidence that therapeutic gene-bearing viruses were being disseminated away from the tumor site via the blood stream, Yuan said. "In the...

Double trouble: Cells with duplicate genomes can trigger tumors

...andy King and colleagues at Harvard Medical School reports that tetraploid cells may arise more frequently than had been thought. According to Pellman, the instability of tetraploid cells may have played a role in evolution, because many organisms, including humans, are thought to have undergone ancient gen...

Brain activity related to processing faces is similar in people with, without autism

...ces. The research also counters previous published reports that the face-processing area at the back of the brain is under-responsive in people with autism, and it suggests that specific behavioral interventions may help people with autism improve their ability to interact socially. The new research will be...

Breaking the mold: Research teams sequence three fungus genomes

...shoyu (soy sauce) for 2,000 years. The third paper reports the genome sequence of model organism Aspergillus nidulans and compares the organism to A. oryzae and A. fumigatus . The work was carried out collaboratively at several institutions in the U.S., U.K., Spain, Japan, France, Brazil, Austria, Switz...

Software might revolutionize glucose monitoring in critically ill patients

...journal BMC MedicalInformatics and Decision Making reports that GRIP, a computersoftware that assists in the monitoring of glucose levels incritically ill patients, saves nurses time and effort and is moreefficient than the paper-based method currently used in manyintensive care units (ICUs). Monitoring bloo...

PET imaging reveals the immune system at work

...itte at UCLA's Jonsson Comprehensive Cancer Center reports the results of experiments that enabled the group to tune in to the cellular battles waged by the immune system deep in the body. Using positron emission tomography or PET, Witte and his colleagues were able to observe key cells of the immune system ...

Jefferson biologist coaxing human embryonic stem cells to make dopamine with simpler, faster method

Using positron emission tomography or PET, Witte and his colleagues were able to observe key cells of the immune system ...

Sangamo BioSciences demonstrates its ZFP treatment protects cells from HIV infection

...ent months two trials have been halted, one due to reports of liver toxicity of the candidate drug. We believe that using ZFNs to permanently modify the CCR5 gene specifically in T-cells and thus directly block the expression of the protein on the surface of these cells may have several advantages over the ...

Recreating 'Flowers for Algernon' with a happy ending

...disabilities. The Nov. 8 issue of Current Biology reports the findings, which were studied in mice bred to develop the disease, called neurofibromatosis 1 (NF1). The results proved so hopeful, that the Food and Drug Administration approved the use of the drugs in three clinical trials currently under rev...

From one cell, many possible cures

...tate University research team in Tallahassee, Fla. reports that it has designed a biomedical device that will allow stem cells derived from adult bone marrow to be grown in sufficient quantities to permit far more research -- and allow faster growth of tissues that can be transplanted into patients. Teng Ma...

How E. coli bacterium generates simplicity from complexity

...lues about how human cells operate, the PNAS paper reports that only a handful of dominant metabolic states are found in E. coli when it is "grown" in 15,580 different environments in computer simulations. "When it comes to genomes, a great deal of complexity boils down to just a few simple themes," said Be...

In SAD patients, autumn antidepressants can prevent winter depression

... depression throughout the fall and winter months, reports a study in the Oct. 15 issue of Biological Psychiatry, official journal of the Society of Biological Psychiatry, published by Elsevier, a world-leading scientific and medical publisher. "These are the first systematic studies that indicate that SAD ...

New evidence supports century-old theory of cancer spread

...m the late 1960's up to today there have been many reports of tumor hybrids." "Aichel implored future scientists to study cancer cells 'from all angles' for evidence of hybridization," Pawelek added. "It is remarkable that a century later we are doing just that. Were he alive today, Aichel would likely be b...

Wild birds help to create human flu vaccine

...rs. William Karesh and Martin Gilbert responded to reports of the avian influenza outbreak in Kovsgol Province near the Russian border from the Mongolian Ministry of Food and Agriculture, which conducted preliminary testing from the wild birds. The highly pathogenic avian flu-H5N1 finding was confirmed by ...

Scientists fetch useful information from dog genome publications

...arch . In one of the publications, Lark's group reports forty QTL, or quantitative trait loci, that are responsible for determining skeletal size in dogs. A striking aspect of these loci is that they control functionally related skeletal traits. "For example," says Lark, "one of the QTL that we identifi...

Access to existing medical treatments could save more lives than spending to improve the treatments

...aken by all patients who could benefit. They cited reports that Americans receive only half of recommended health care services and that disparities in care are worse for minorities and disenfranchised patients. The study poses a contrast between efficacy, or how well a treatment works, and what they call t...

Serious adverse reactions to smallpox vaccine appear to be limited

...ast 1 dose of smallpox vaccine. VAERS received 822 reports of adverse events following smallpox vaccination (overall reporting rate, 217 per 10,000 vaccinees). A total of 590 adverse events (72 percent) were reported within 14 days of vaccination. Nonserious adverse events (n = 722) included multiple signs ...
