Restoring seagrass beds: Is it for the birds?

.... Heck and Dindo will also plant birdstakes in the damaged grassbeds, hoping to attract seabirds to use the stakes as a resting area where they can "do their business" and fertilize the shoal grass beneath them. "Birdstakes have proven successful in the Florida Keys," comments Dr. Heck. "We're placing sign...

Brain's own cannabis compound protects against inflammation

.... Importantly, they found that adding AEA to such damaged brain tissue abolished inflammatory damage to the ...mical. They found similar effects of AEA when they damaged the brain tissue by depriving it of oxygen and glucose. The researchers also found that when they u...

Manchester scientists create new bio-gel for 3D cell culture

...d by the body to grow new cells in order to repair damaged tissue. Like the ECM, the gel acts like a scaffold in which cells can grow. In their paper, 'Nanostructured Hydrogels for Three-Dimensional Cell Culture Through Self-Assembly of Fluorenylmethoxycarbonyl-Dipeptides', Dr Rein Ulijn and collaborators d...

Science finds new fix for UV-damaged skin in arthritis treatment

..., accumulated sun exposure has already permanently damaged their skin cells, causing them to overproduce pigment that shows up as unsightly dark splotches and uneven skin tone over time. But new research indicates that glucosamine - a compound best known for treating arthritis ?can actually help stop the for...

Researchers find molecular 'brake' to cell death

...programmed" to die, or is initiated when a cell is damaged beyond repair or infected by a virus. Apoptosis is rare in cancer because tumor cells have adapted biological pathways to circumvent cell death, so many anti-cancer therapies focus on inducing apoptosis in these cells, Tang says. But the notion of h...

Novel connection found between biological clock and cancer

...he signal response pathway that begins when DNA is damaged and results in a temporary stoppage of cell division until the damage is fixed. The researchers found that the resetting effect of DNA damage requires the period-4 clock protein, and that period-4 is the homolog, the Neurospora version, of the mammal...

Researchers map out networks that determine cell fate

...or the therapeutic use of stem cells to rejuvenate damaged tissues. Understanding of leukemias also could be aided by insight into this regulatory circuitry, Singh said. Many leukemias exhibit mixed-lineage patterns of gene expression, for example of both macrophage and lymphocyte genes. "It may be that...
