...separated from each other without any damage. This detachment
is reversible: If the pH value is raised again, making the solution less acidic, the gel and brush stick to each other once again. This cycle can be repeated many times by simply changing the pH value. Possible applications for such smart surface p...
Muscle weakness: New mutation identified
...tor protein myosin attachment rate to and a faster detachment
rate from actin, caused by the mutation, results in a reduced number of myosin molecules in the strong actin binding state and muscle weakness. The results also implicate a potential role of the regulatory protein tropomyosin in modulating contracti...
Researchers figure out what makes a simple biological clock tick
...attached to the KaiC molecules. The attachment and detachment
of phosphate groups a process called phosphorylation and dephosphorylation is a common method of protein regulation. When KaiC is phosphorylated it interacts in different ways with other proteins in the cell than it does when it is dephosphorylated...

Scientists focus on 'dwarf eye'
...cells. Blindness occurs when these cells die after detachment
of the retina from the RPE. Beneath the RPE are two layers of structural tissue that give the eye its shape. During childhood, these tissues stretch, like a balloon, as the eye grows. "The RPE is believed to be the key link in signaling these tissue...
Scripps scientists identify target of an immune suppression molecule called CD22itself
...hese phosphates regulates B cell activation, their detachment
downregulates B cell activation. This is where CD22 comes in. It, like the B-cell receptor, is an integral membrane protein and has surfaces on both sides of the B cell membrane. On the inside of the membrane is a domain that recruits an enzyme know...

...49,844)," for treating retinal detachment. Retinal detachment
is caused by fluid under the retina. The invention calls for injecting biocompatible magnetic fluid inside the eye and using a magnetized scleral buckle to pull the fluid to a specific site and close the hole in the retina. The patent is shared by VT...
