Brain inflammation may be friend, not foe, for Alzheimer's patients

...ications for the development of a vaccine or other strategy to protect against or fight off Alzheimer’s. Work on an Alzheimer’s vaccine has at times been promising, reducing the number of plaques in the brains of animals and a few people with the disease, but it’s also been fraught with difficulty, producing ...

Researchers find 24 species believed new to science in Suriname rainforest

...ng conservation of the Amazon rainforest a crucial strategy for minimizing climate change. The burgeoning global carbon market creates new economic value for carbon stored in standing rainforest, providing fresh incentive for developing nations such as Suriname to avoid deforestation....

Migration alert -- How tumor cells home in on the lymphatic system

...search shows how tumor cells use a clever chemical strategy to exploit this slow, one-way flow in order to migrate to functional lymphatic vessels. As part of their intercellular drainage job, lymphatic tissues secrete small quantities of a signaling molecule. Cells migrate towards high concentrations of...

Study identifies 5 genetic themes key to keeping stem cells in a primitive, flexible state

...e expression in different types of stem cells, the strategy used in this study was unique. Rather than simply searching for any genes expressed by stem cells, the researchers looked for genes whose expression was also correlated with the master stem cell regulator gene Oct4. They also applied very rigorous an...

Gene therapy study shows safety and statistically significant improvement in Parkinson's disease

...g to calm the STN over-activity. The value of this strategy has been demonstrated in previous human studies where reducing STN activity by either electrical stimulation or lesioning can help ameliorate the symptoms of advanced Parkinson’s disease. The Phase 1 study was not specifically designed to assess e...

Researchers use MRI to predict recovery after spinal cord injury

...indings could result in a more aggressive clinical strategy for patients who may appear to have a severe SCI but may indeed have the capacity for substantial neurological recovery."

They tracked both individual-level decisions and population-level variables ?that is, the yearly vaccine coverage level and influenza prevalence, where prevalence is d...

Keeping the immune system from starting a 'food fight'

... however, that the realization of such a treatment strategy remains uncertain and would require years of continued investigation. Cells and organisms must strike an appropriate balance between nutrient sufficiency and surplus, the researchers explained. While adequate amounts of nutrients must be obtained ...

Alien plants attack using 'resource conservation' as weapon, researchers say

Funk pointed to recent experiments that tried to eliminate invaders by deliberately reducing available resources-for example, by mixing sugar into the soil to lock up nutrients or by blocking sunlight with tarps...

Fat screen delivers plant-derived chemical with antidiabetic effects
