Nerve navigation findings prompt new direction for spinal cord research
...dhesion kinase is activated that tells the axon to reorganize its structure or cytoskeleton and the restructured axon knows how to move. When they delete the kinase, the axon doesn't make the proper journey or the proper connection. Developing axons can sense and navigate their environment but how ...Exercise has a more powerful impact on the brain than previously thought
...at brain plasticity -- the ability of the brain to reorganize itself in response to sensory stimulation -- may not be restricted to nerve cells and their synapses. Other elements of brain tissue, including its capillaries, may be involved as well. Understanding how brain plasticity works is essential to develop...Immune alarm system can both amplify and silence alerts, scientists find
...enting cell, proteins on the surface of both cells reorganize and interact at the point of contact, potentially enhancing the transmission of a key message to the T cell: "Invaders are here, start the attack!" Because nerve cells also have specialized structures at areas known as synapses where they pass messag...Brookhaven spotlights: News from the March 2003 American Chemical Society Meeting
...elf-assembled film which supports the bridge might reorganize itself. "Nanometer-sized molecular structures are made of 'bundles' of molecules, so it is challenging to understand how electrons move around them," Newton says. "What we have found shows that we still need a better understanding of electron transpo...Surveys find chronic conditions a widespread concern

A challenge of the 21st century will be to reorganize the medical care system around the treatment of chronic conditions and especially those with multiple chronic conditions," explained Gerard Anderson, PhD, professor of health policy and management and international health at the School of Public Heal...NIAID expands vaccine testing network

The remodeling process controlled by MMPs can be either beneficial or deleterious based on location, timing, or extent. Dr. ...Stroke news tips for Thursday, Feb. 7, 2002

Brian Silver, M.D., Henry Ford Hospital, Detroit, Mich.......The finding suggests that our brains mayconstantly reorganize themselves throughout our lives in an effort to ensurepeak mental performance. The study, conducted by researchers at Brandeis University, the University ofToronto, and the Baycrest Centre for Geriatric Care in North York, Ont., isdetailed in the Oc......dence revealedthat even the adult brain is able to reorganize and optimize its microstructureand internal connections. For instance, it has been possible to optimizeinformation transfer between communicating nerve cells by short intensiveelectrical stimuli and to measure this improvement as an increased respons...
