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

...hy people. It’s recognized as a critical player in bringing about much of the brain damage that follows a stroke and brain injury, so it’s no surprise that its presence in the brains of Alzheimer’s patients would be assumed to be part of the problem. In the original development of his mouse, Shaftel worked...

A new plant-bacterial symbiotic mechanism promising for crop applications

...in rhizobia is promising for future techniques for bringing these bacteria into association with different leguminous plants. It therefore becomes possible to increase agricultural production of a greater number of important plants, notably in tropical countries, while cutting down the use of fertilizers....

Endosome-mediated signaling in plants

...actually facilitate signaling through the cell, by bringing signaling components in contact with their activated receptors. Drs. Geldner, Chory and collaborators now extend the range of endosome-mediated signaling into the plant kingdom. The researchers show that the growth-promoting brassinosteroid recept...

Fat fish put obesity on the hook

...ency and power of the drug discovery process, thus bringing new medicines to the market faster and cheaper.” In the study, researchers caused obesity in zebrafish by introducing the same type of genetic mutation that causes severe obesity in humans. The genetic change blocks the activity of a receptor, the...

Mice with a migraine show signs of brain damage

...served the unexpected: While blood flow increased, bringing more oxygen overall to the brain, there were still pockets of severe hypoxia. The brain was working so hard to restore the chemical balance and to resume normal cellular function, using so much oxygen, that the brain simply couldn’t keep up with the ...

World's leading scientists announce creation of 'Encyclopedia of Life'

...e Library joined together to initiate the project, bringing together species and software experts from across the world. The Missouri Botanical Garden has become a full partner, and discussions are taking place this week with leaders of the new Atlas of Living Australia. The Encyclopedia today also announce...

OHSU surgeon implants donated tissue allografts

... and I am delighted I could be an integral part of bringing this partnership to fruition. The result very well could be a lifetime of painlessness for many patients who otherwise would be suffering from often-debilitating pain and arthritis." Pete Jenkins, JRF executive director, believes OHSU's involvemen...

Cold sore virus might play role in Alzheimer's disease

...me scientists, that herpes somehow plays a role in bringing about Alzheimer's disease. The work links a form of the ApoE gene known as ApoE-4, which after advanced age is the leading known risk factor for getting Alzheimer's disease, with the form of herpes ?herpes simplex 1 or HSV ?that infects more than 80...

New mechanism for nutrient uptake discovered

...s. "Every cell in every organism has a system for bringing in nutrition and expelling waste," explained lead author Dominique Loqué. "Some are through pore-like protein structures called transporters, which reside at the surface of the cell's outer membrane. Each pore is capable of transporting nutrients ind...

Uganda's mountain gorillas increase in number

...much needed foreign revenue for Uganda annually by bringing paying travelers into the company of mountain gorillas. Four of the 30 family groups are habituated for tourism, or conditioned to tolerate the presence of humans for short durations. The other mountain gorilla stronghold is located just south of...

Research project tackles 'regeneration' gap

...hen the body’s inherent healing powers. "We are bringing together the best of the developmental biology world with the best of the stem cell world and starting the conversation, with the focus on how to get regeneration to work in a mammal," said Edward Scott, Ph.D., a professor of molecular genetics and d...

Cracking the egg

... is fascinating. As we all know, the basics entail bringing together an egg and a sperm, a whole lot of cell division and growth, and sooner or later a young organism that carries a mix of genes from both parents. There are many startling events along the way, but one of the most fundamental and important is ...

An AIDS-related virus tricks cells to become tumors, new Penn study finds

...LANA to bind to tumor suppressors p53 or VHL, thus bringing them into the active ubiquitylation complex. Once in the complex, the tumor suppressors are targeted for degradation. Tumor suppressors, as their name implies, prevent or limit the growth of tumors in numerous ways. One way the tumor suppressors ...

Road-crossing in chimpanzees: A risky business

... potentially unsafe areas, such as waterholes, and bringing up the rear when retreating, but comparable data on great-ape progression orders have been lacking. Crossing of man-made roads, sometimes necessitated by intersection with longstanding chimpanzee travel routes, presents a new situation that calls for...

Reef warns of sea level rise

...reefs along it, the results of the Leeuwin current bringing coral larvae down from Indonesia and northern Australia over many tens of thousands of years. Together these reefs indicate what occurred during the last big sea level rise. "At the time when this reef grew we know that atmospheric CO2 levels were ...

Memories: It's all in the packaging, scientists say

...rical evidence for how critical this region is for bringing the constituents of a memory together in the brain. "Memory is more than a sum of its parts. A complete memory of an event requires that the features of the event be brought together and processed by the brain as a common perceptual representation...

Plant-cell-produced technologies-cutting edge approach to bringing solutions to the market

...mple of Dow AgroSciences' cutting edge approach to bringing highly novel and differentiated solutions to the market," said Jerome Peribere, Dow AgroSciences' president and CEO. The conference on 7 June, entitled "Innovations in Biosciences for Animal and Human Health" will highlight major bioscience developm...

MIT engineers probe spiders' polymer art

...spider silk its unrivaled strength and durability, bringing closer to reality the long-sought goal of spinning artificial spider silk. Manufactured spider silk could be used for artificial tendons and ligaments, sutures, parachutes and bulletproof vests. But engineers have not managed to do what spiders do e...

Researchers unveil strategy for creating actively-programmed anti-cancer molecules

...e immune system cell that makes antibodies. "By bringing together chemistry and biology, our approach provides a way to break the traditional one antibody-one target axiom of immunochemistry," said Lerner. "This new hybrid technology offers great possibilities for the enhanced treatment and diagnosis of a ...

Polynesia explorers created worldwide web of scientific knowledge

...ns, and from Polynesian travelers who came aboard, bringing "their own thirst for knowledge, power, and prestige," Liebersohn wrote. In truth, their enterprises engaged a cast of thousands, all of whom interacted in the "multifaceted network": patrons, collaborators, philosophers back home, missionaries abro...
