Nervous system-specific transmembrane proteasome complex that modulates neuronal signaling through extracellular signaling via brain activity peptides
The inventors surprisingly found that neural stimulation caused the synthesis and degradation of proteins into peptides which were then secreted into the cell media within minutes of stimulation by a novel neural-specific and membrane bound proteasome (neuronal membrane proteasome or NMP) that is transmembrane in nature. These secreted, activity-induced, proteasomal peptides (SNAPPs) range in size from about 500 Daltons to about 3000 Daltons. Surprisingly none of the peptides appear to be those previously known to have any neuronal function.

Trowel for finishing cementitious materials
The present invention provides a modified finishing trowel tool comprising a blade having a contact surface with a planar and convex component. One edge of the longitudinal edge of the blade is configured with a protruding convex surface such that when pushed or parallel with the trowel handle a uniform concave channel way is formed along the surface of the semi-cured cementitious surface. Thus when the trowel is oriented in a substantially horizontal position along the surface and moved along its longitudinal direction, a concave indentation is created in the cementitious material. This trowel is particularly useful in forming a uniform drainage ditch along the surface of the final, cured cementitious material such as along the perimeter of a cement basement floor. |
