Beekeepers work hard for the honey, despite changing tupelo forest

...ey production, an important regional industry that contributes about $2.4 million a year to Florida's economy. The researchers' findings will allow beekeepers to develop collective strategies to defend their livelihood, Watson said. That's important because helping the beekeepers will in turn help the survival...

How bad is malaria anemia? It may depend on your genes

...xygen molecules. "Demonstrating that MIF clearly contributes to severe anemia suggests new ideas for therapies that can block MIF in malaria patients," says the study's senior author, Richard Bucala, M.D., Ph.D., a professor of medicine at Yale University School of Medicine. The research team also found diffe...

Protein's role in regulating cell death sets direction for cancer research

...herapeutic drugs. This study showed that calpain contributes to the activation of AKT and JNK, two key players in the signaling pathways that control cellular responses to different death stimuli. These discoveries suggest that calpain inhibitors might improve the ability of chemotherapeutic drugs or radiation...

Researchers find protein that silences genes

...aard explained. When they are removed by HDA6, it contributes to gene silencing. Using antibodies that recognize specific histone modifications that occur on the genes when they switch from off to on, the group was able to confirm that the deacetylation specificities they observed for HDA6 in the test tube fit...

ABCB6 is key to production of heme in hemoglobin

...fere with this system," Schuetz said. "So our work contributes to the overall picture of how disruption of the biochemical pathway of heme production can cause a variety of serious diseases." ...

Epstein-Barr virus might kick-start multiple sclerosis

...our hypothesis is that the altered immune response contributes to the development and progression of the disease." Lünemann started the research as a postdoctoral fellow at NIH. He is continuing to investigate the role of Epstein-Barr virus in MS in the lab of Christian Münz, a Rockefeller University researche...

Inheriting a tendency to brain infection

...enerally agree that an individual's genetic makeup contributes in subtle ways to susceptibility to infectious disease, new findings from researchers in France support the controversial idea that an error in a single gene is enough to dramatically alter an individual's susceptibility to certain infections. Ho...

Inflammation markers identify fatigue in breast cancer survivors

...rive initial immune responses within people. "IL-6 contributes to an activation of monocytes in the blood, and enables antigen presenting cells to activate T cells as part of the cellular immune response," Dr. Irwin said. The second component of the marker is an index measured by the level of T cells that are c...

Study offers innovative profile of enzyme that aids tumor growth

... a key regulator of a lipid signaling network that contributes to cancer," said Benjamin F. Cravatt, a Scripps Research professor and a member of its Skaggs Institute for Chemical Biology who led the study. "The heightened expression of KIAA1363 in several cancers indicates that it may be a critical factor in tu...

Jefferson scientists find high glucose before surgery raises risk of dangerous complications

... some 600,000 patients develop PE, which causes or contributes to as many as 200,000 deaths annually in the U.S. He notes that recent studies have begun to show connections between increased blood sugar and a greater risk of dying or of medical complications for hospital patients in intensive care or cardiac c...

'Tribbles' protein implicated in common and aggressive form of leukemia

...ples from AML patients, further suggesting that it contributes to AML. Overall, the findings suggest that Tribbles induces AML by inactivating the C/EBPá protein. The results were published in this week's issue of Cancer Cell. AML is a malignancy that arises in white blood cells and develops when there is a ...

From hot springs to rice farms, scientists reveal new insights into the secret lives of archaea

...n the planet. Studies have shown that rice farming contributes between 10 and 25 percent of global methane emissions, thanks in large part to methanogenic archaea, which crank out tons of methane gas when they break down organic matter in flooded rice fields. AGU panelist Ralf Conrad of the Max-Planck-Institute ...

'Erectile dysfunction' drugs heighten natural anti-cancer activity

...lizes a dietary supplement called L-arginine, also contributes to dampening the immune system through MDSCs much like nitric oxide, and its production can be reversed by sildenafil. "Impotence drugs won’t cure cancer," Borello cautioned, "but could be used in addition to standard chemotherapy or immunotherap...

Hopkins researchers discover how brain protein might control memory

...opkins have figured out how one particular protein contributes to long-term memory and helps the brain remember things longer than an hour or two. The findings are reported in two papers in the Nov. 9 issue of Neuron. The protein, called Arc, has been implicated in memory-linked behaviors ranging from song lear...

Malaria may fuel spread of HIV in sub-Saharan Africa

...m's failure to deal with the challenge of HIV/AIDS contributes directly to its failure to tackle other public-health challenges such as malaria and tuberculosis," Abu-Raddad said. "As long as HIV/AIDS continues to spread, it will aggravate the difficulties we face with these other diseases and may contribute to ...

Learning during sleep?

...eted in very different ways. "Either the mechanism contributes to memory consolidation, or the information transfer from one part of the brain to another during sleep does not proceed as we have previously assumed." The brain researchers now want to find out which of the possible explanations applies. In any ...

Growth factor stimulates rapid extension of key motor neurons in brain

...ate in ALS and related disorders, and their damage contributes to loss of motor function in spinal cord injuries. Since they are embedded among hundreds of other types of neurons in the cerebral cortex, it has been difficult to study CSMN, and little has been known about cellular and molecular factors that cont...
