In contrast to inner hair cells [12], [17], [23] there has been no evaluation of photoreceptor terminals focused on the distribution and location of hemi-fused and fully fused synaptic vesicles to map transmitter release sites in these cells.
In retinas of both light- and dark-adapted mice, hemi-fused and fully fused vesicles were located along the entire surface of the rod spherule adjacent to horizontal cell axonal endings.
There is a high density of hemi-fused and fully fused vesicles near the base of the synaptic ribbon and along the slope of the synaptic ridge in light and dark (Figs.
The rod spherule reconstructions used in this study exhibit an isotropy in plane resolution of ∼3 or ∼6 nm depending on magnification, which is sufficient to identify hemi-fused and fully fused vesicles at the plasma membrane [43].
The distribution of hemi-fused and fully fused vesicles indicates that docking and exocytosis occurs along the entire region of the rod spherule facing the horizontal cell axonal endings, and not just at or near the synaptic ribbon's base (Figs. 6 & 7).
In the light, rod spherules contained ∼470 vesicles that were hemi-fused and ∼187 vesicles that were fully fused (omega figures) with the plasma membrane.
This is in part because babies' necks are weak, of course, but also because the bones in the skull are not yet fully fused together.
The smaller cup, made from the child's skull, would have leaked because the cranial bones had not fully fused together, but the larger two might have carried food or around two pints of liquid.
Barack and Michelle Obama are also a more fully fused political team than ever before, with no other jobs to distract them, no doubts about the worthiness of the pursuit dogging them.
This injury occurs only in adolescence, when the bones in the arm have not yet fully fused, and may have been caused by attempts to practise with an adult longbow.
Mr. Paterson's poem is a 21st-century ode to regeneration (fontanelles are those soft spots on a baby's head where the skull hasn't fully fused yet), but it's also about the deep satisfactions of disappearing.
