Second door discovered in war against mosquito-borne diseases 2013-07-17

By Michigan State University

In the global war against disease-carrying mosquitoes, scientists have long believed that a single molecular door was the key target for insecticide. This door, however, is closing, giving mosquitoes the upper hand.

How quality control works in our cells 2013-07-17

By University of Bern

A cellular control mechanism prevents the production of defective proteins in our cells. A team of researchers has now obtained valuable insights into this vital mechanism that could lead to new therapeutic approaches for genetic diseases.

New tissue engineering breakthrough encourages nerve repair 2013-07-17

By Open University

A new combination of tissue engineering techniques could reduce the need for nerve grafts, according to new research. Regeneration of nerves is challenging when the damaged area is extensive, and surgeons currently have to take a nerve graft from elsewher

Bacteria communicate to help each other resist antibiotics 2013-07-17

By University of Western Ontario

New research unravels a novel means of communication that allows bacteria such as Burkholderia cenocepacia (B. cenocepacia) to resist antibiotic treatment. B. cenocepacia is an environmental bacterium that causes devastating infections in patients with cy

Breakthrough could lead to 'artificial skin' that senses touch, humidity and temperature 2013-07-17

By American Technion Society

Using tiny gold particles and a kind of resin, a team of scientists has discovered how to make a new kind of flexible sensor that one day could be integrated into electronic skin, or e-skin. If scientists learn how to attach e-skin to prosthetic limbs, pe

Biomedical uses for hydrogels explored 2013-07-17

By University of Akron

Scientists are researching hydrogel, the gelatinous substance that, because of its toughness and plasticity, has several biomedical applications, including cartilage repair, implants for minimally invasive surgery and drug delivery.

New mechanism for human gene expression discovered 2013-07-17

By University of Chicago Medical Center

Researchers have discovered the first human "bifunctional" gene -- a single gene that creates a single mRNA transcript that codes for two different proteins, simultaneously. Their finding elucidates a previously unknown mechanism in our basic bi

Technological breakthrough paves the way for better drugs 2013-07-17

By Karolinska Institutet

Researchers have developed the first method for directly measuring the extent to which drugs reach their targets in the cell. The method could make a significant contribution to the development of new, improved drug substances.

Exposure to stress even before conception causes genetic changes to offspring 2013-07-17

By University of Haifa

A female’s exposure to distress even before she conceives causes changes in the expression of a gene linked to the stress mechanism in the body — in the ovum and later in the brains of the offspring from when they are born, according t

Development of hands and feet may help unlock evolution's toolkit 2013-07-17

By Yale University

Thousands of sequences that control genes are active in the developing human limb and may have driven the evolution of the human hand and foot, a comparative genomics study has found.

Targeting errant immune system enzyme kills myelodysplastic cells 2013-07-17

By Cincinnati Children's Hospital Medical Center

Scientists have successfully targeted a malfunctioning immune system enzyme to kill diseased cells from patients with myelodysplastic syndrome -- a blood disorder and precursor to leukemia. Researchers say their successful laboratory tests in human MDS ce

Egg donation in European clinics: Why do women do it? 2013-07-17

By European Society of Human Reproduction and Embryology

Egg donation is now one of the major reasons why couples travel abroad for fertility treatment. Because this growing trend may circumvent regulations at home or raise concerns about financial inducement, it has also become one of the most controversial. Y

New approaches to understanding infection may uncover novel therapies against influenza 2013-07-17

By Seattle Biomedical Research Institute (Seattle BioMed)

The influenza virus’ ability to mutate quickly has produced new, emerging strains that make drug discovery more critical than ever. For the first time, researchers have mapped how critical molecules regulate both the induction and resolution of

Happily married means a healthier ever after 2013-07-17

By Brigham Young University

New research finds that people in happy marriages live less "in sickness" but enjoy more of life "in health." In a 20-year longitudinal study tracking health and marriage quality, a family life researcher found that as the quality of m

Brain structural deficits may contribute to increased functional connections between brain regions implicated in depression 2013-07-17

By Elsevier

Major depressive disorder is associated with a dysregulation of brain regions including the prefrontal cortex and limbic system. The relationship between structural and functional abnormalities in these brain regions in depressed patients is far from clea

IVF for 200 euro per cycle: First real-life proof of principle that IVF is feasible and effective for developing countries 2013-07-17

By European Society of Human Reproduction and Embryology

A study performed in Belgium has shown that low-cost IVF for developing and poor resource countries is feasible and effective, with delivery rates not much different from those achieved in conventional IVF programs. This proof-of-principle study, say the

Maintaining immune balance involves an unconventional mechanism of T cell regulation 2013-07-17

By St. Jude Children's Research Hospital

A new study challenges prior understanding of the process regulating specialized T cells that are essential for a balanced immune system.

Gunning for trouble: Guns and aggression in young assault victims 2013-07-17

By University of Michigan Health System

They're young. They've been injured in an assault -- so badly they went to the emergency room. And nearly one in four of them has a gun, probably an illegal one. What happens next? A new study provides data that could be important to breaking the cycle of

Improved outlook for immune-based therapies: Assay identifies T cells most capable of fighting infections and cancers 2013-07-17

By Technische Universitaet Muenchen

The idea of fighting infections and even cancers by inducing protective immune responses may now be a step closer to clinical practice. Researchers have removed a major obstacle to widespread use of adoptive transfer therapy, in which a patient receives &

Shape-shifting disease proteins may explain neurodegenerative variation 2013-07-17

By Perelman School of Medicine at the University of Pennsylvania

Researchers have shown one disease protein can morph into different strains and promote misfolding of other disease proteins commonly found in Alzheimer's, Parkinson's and other related neurodegenerative diseases.
