Nuclear pore micrograph and nuclear pore model

Yesterday’s post on a nuclear pore from a type II alveolar cell i pursued a little more, trying to establish a relative size for the current image and models of the nuclear pore complex, and a website posted this terrific image which i made transparent and placed into the transmission electron micrograph of  of a nuclear pore from my studies.  There are some issues using their image which is a top down view, and my image which is sectioned more from the bottom up, but it is an interesting match.  One thing i like about this particular model as opposed to many of the diagrams seen online is that it does NOT extend the nuclear basket too far into the nucleoplasm and have the inner and outer nuclear membranes too spaced apart in the area just adjacent to actual pore.  It appears in my micrographs as if the cytoplasmic filaments are greater length than any basket structure seen on the nucleoplasmic side.   So this more compressed model (fading in and out of my micrograph below) works best.

Verge of a dream: I think it might be bliss

keys_staffI think it might be bliss
as our eyes can’t quite adjust
as the dress rehearsal
lets out in the
phosphorescent light.
I think it is contentment
that is casual perfection
in strolling down
the streets of yards
that bloom without a
thought to end yet.
It’s just a guess or story
we tell to
make their lives
a romance though we
see them
only in a window.
Little thought is given
As the open
club door
lets blue notes carry
their way to freedom.
