A second, narrow polar channel, lined by the unwound stretches of H5C, H12C and the cytoplasmic halves of H6 and H13, extends from the cytoplasmic surface to the region near the deepest point of the funnel.
An amendment that would have required private health insurance plans to cover contraceptives as a way to reduce the need for abortions was defeated, as was a second, narrower health exception.

A second narrow polar channel may facilitate proton uptake from the cytoplasm.
The antiporter has a funnel-shaped cavity that faces inwards (into the cell) in both acidic and alkaline conditions, although a second narrow channel that is open in alkaline conditions is blocked in acidic conditions by small protein rearrangements.
Since sRNAs involved in gene silencing are mostly considered to fall within the 17 to 26 nt size-range, a second narrow range library (NRL) was prepared for each sample using size-selected sRNAs to increase the sequence depth of these sRNAs.
However, recent surveys of low-mass stars have also shown the presence of a third narrow band at 2143 cm-1 (blue component) (Pontoppidan et al., 2003).
A third narrow wire in the T state seems to connect the proton-binding site to the cytoplasm (dashed black lines), but the positively charged R971, which traverses this water wire, likely blocks H+ leakage.
England slipped to a second chastening narrow defeat of the autumn as a disciplined South Africa held them at bay in a frantic, contentious finale.
He signed a second, slightly narrower version in March after the first was blocked by courts.
