#3-D printed guide helps regrow complex nerves after injury A national team of researchers has developed a first-of-its-kind,
3d printed guide that helps regrow both the sensory and motor functions of complex nerves after injury.
The groundbreaking research has the potential to help more than 200,000 people annually who experience nerve injuries or disease.
Because of this complexity, regrowth of nerves after injury or disease is very rare according to the Mayo Clinic.

This lesion, a damaged form of the normal DNA base cytosine, is caused by the reactive molecule hypochlorous acid the main ingredient in household bleach
The lesion 5clc, was present in remarkably high levels within the tissue, says John Essigmann, the William R. 1956) and Betsy P. Leitch Professor in Residence Professor of Chemistry, Toxicology and Biological engineering at MIT,
who led the current research. hey found the lesions were very persistent in DNA, meaning we don have a repair system to take them out,
Essigmann says. n our field lesions that are persistent, if they are also mutagenic, are the kind of lesions that would initiate cancer,
he adds. DNA sequencing of a developing gastrointestinal tumor revealed two types of mutation: cytosine (C) bases changing to thymine (T) bases,
the researchers decided to investigate the lesion further, in a bid to uncover if it is indeed mutagenic.
the researchers first placed the 5clc lesion at a specific site within the genome of a bacterial virus. They then replicated the virus within the cell.
the researchers replicated the genome containing the lesion with a variety of different types of polymerase,
the researchers predict that accumulation of the lesions would increase the mutation rate of a cell up to 30-fold,

#Study shifts understanding of how bone fractures heal It time to rewrite the textbook description of bone fracture healing.
a protein that was thought to play a key role in fracture healing, is required not. Instead, the breakdown of fibrin is essential for fracture repair.
The findings, reported in the August issue of the Journal of Clinical Investigation, shift understanding of how fractures heal
and have implications for efforts to promote fracture repair. any of the current pharmaceutical protocols are based on using fibrin to promote fracture healing,
said Jonathan Schoenecker, M d.,Ph d, . assistant professor of Orthopaedic Surgery and Rehabilitation. n certain instances it may help,
Bone biology does not require fibrin to heal a fracture. Fibrin is involved in blood clotting; it forms a meshlike net that traps platelets to form a clot.
Schoenecker said. hen you have a fracture, you have a huge disruption of that vascularity.
Since fibrin is the main protein at the site of a fracture, it was thought to promote repair by providing a scaffold for the initial phase of new bone formation.
however, that fracture repair was normal in mice missing the fibrin precursor fibrinogen. The investigators had reported previously the importance of vascular re-connection for bone fracture healing.
Using imaging techniques they developed to simultaneously study angiogenesis (new blood vessel growth) and bone formation after fracture,
they found that blood vessels grow first at the ends of the fracture, extend and reconnect. Then new bone forms. herefore, any condition associated with vascular disease
and thrombosis will impair fracture healing, Schoenecker said. It follows that if fibrin is removed not efficiently,
Genetic manipulations to deplete fibrinogen in these mice restored normal fracture repair. ibrin puts a cog in the machine

who was paralyzed after suffering a spinal cord injury more than a decade ago. An array of electrodes was placed in the volunteer's sensory cortex (part of the brain that identifies touch)
when given at different stages after the injury has occurred. Laboratory studies conducted in the University's School of Medical sciences have confirmed that changes in brain water channels over time play a critical role in traumatic brain injury.
This swelling can occur for days after the initial injury and is frequently life-threatening Dr Burton says.
but in the case of traumatic injury or stroke they become a pathway of vulnerability that allows swelling.
A second drug used later in the progression of the injury acts to enhance the water channel activity letting superfluous moisture out when needed.
By using both of these compounds--a blocker at the early stage of injury and an activator at the later stage--we're able to complement the brain's natural healing processes
because it clarifies the roles of aquaporins in the brain during the short and long-term responses to traumatic head injury.
Most current therapeutic approaches are limited in their ability to reduce injury-induced brain swelling and no treatments are available to resolve excess fluid at a later stage.
New approaches that can improve the outlook for patients especially in the later stages of injury development would be of great benefit she says.
