Scientists find genes involved in the battle between Hessian flies and wheat

...s plant resistance and use that basic knowledge to enhance the durability of wheat against Hessian fly attack by combining several genes for resistance or through some other novel strategies," said Shukle, senior and corresponding author of the paper. The toxic oxygen compound defense mechanism in resista...

Analysis of rhesus monkey genome uncovers genetic differences with humans, chimps

Researcher to study astronaut bone loss for space biology agency

...it –?in order to stimulate integrin production and enhance or recover IGF-1 receptor function. The IGF-1 will act as a signaling device to allow Long to measure the strength of the interaction between integrins and IGF-1 receptor. "Understanding this interaction, and the role it plays in how bones respon...

Researchers urge monitoring of bone health during chemotherapy

...rapy that decreases bone density could potentially enhance tumor growth in bone," says senior author Katherine Weilbaecher, M.D., assistant professor of medicine and of cell biology and physiology. "But there are things that can be done to counteract this. Physicians should carefully monitor their cancer pat...

HIV protein enlisted to help kill cancer cells

...n tip the balance in favor of death." To further enhance the cancer-killing power of TAT-Bim and similar proteins under development, Hawkins and his colleagues are working on a technique that will concentrate them within tumors while sparing healthy cells. In collaboration with Robert H. Mach, Ph.D. profes...

Sleep enforces the temporal sequence in memory

...one came after during learning. Sleep was found to enhance word recall, but only when the students were asked to reproduce the learned words in forward direction. This finding shows that sleep associated consolidation of memories enforces the temporal structure of the memorized episode that otherwise migh...

Parasite infection may benefit MS patients

...generate strong anti-inflammatory responses, which enhance their survival. Further investigation is warranted in order to identify which molecules cause immune system effects that dampen the inflammatory reactions normally seen in autoimmune diseases, the authors note. They conclude that "induction of a regu...

Brain networks strengthened by closing ion channels

...duction of norepinephrine. Treatments for ADHD all enhance stimulation of the norepinephrine receptors. These new data also have important implications for the researchers' studies of more severe mental illnesses like schizophrenia and bipolar disorder, which can involve mutations of a molecule called DIS...

Antibody signal may redirect inflammation to fuel cancer

...ies may signal specific receptors on leukocytes to enhance the cancer-promoting pathway. Part of the receptor for the antibody known as immunoglobulin appears to be involved, Coussens said. The good news, she adds, is that potential drugs to block this pathway are already being tested in clinical trials t...

Scientists identify a gene that may suppress colorectal cancer

...regulated by modifier genes, which may function to enhance or suppress tumor initiation, growth and/or progression. Atp5a1 is a modifier gene, and it is located on the same chromosome as Apc in mice. Interestingly, the results suggest that the mutant Atp5a1 gene caused the death of tumor cells, prima...

Scientists discover new virus caused deaths of transplant recipients from single donor

...us will enable improvements in screening that will enhance the safety of transplantation. Ian Lipkin, MD, director of the Greene Laboratory and Principal Investigator of the Northeast Biodefense Center, emphasized the importance of academic, public health, and industrial partnership in this work. "This wa...

Leukemic cells find safe haven in bone marrow

...ween these cells, the more likely we’ll be able to enhance the anti-leukemic action of asparaginase and perhaps other anti-leukemic drugs as well," said Pui, a co-author of the paper. "That would reduce the recurrence rate of ALL and continue our successful efforts to increase the survival rate of ALL." ...

Reminding doctors which antibiotics to prescribe cuts C. difficile infection rates

...od to study interventions in other hospitals would enhance the pool of good quality evidence on the best ways to change antibiotic prescribing. It would also enable meaningful comparisons between studies and interventions. The paper is intended to be an example of best practice for reporting such studies...

Nanoparticles can track cells deep within living organisms

...lls are also under investigation in therapies that enhance new blood vessel growth to improve the blood supply to diabetic patients' limbs or to repair blood vessels after a heart attack or bypass surgery. Tracking nanoparticle-labeled cells used in such treatments by MRI imaging would allow physicians to mo...
