Question: Question: Does resident participation affect surgical outcomes , despite introduction of new techniques?
Answer: In the context of this single surgical operation, resident participation does not substantially affect major complication rates. The common residency training paradigm provides clinical experience and supervision without necessarily impacting patient safety. Analysis of additional operations in different settings will be necessary.

Answer: no

Question: Question: Do elevated S100B levels correlate with the severity of encephalopathy during sepsis?
Answer: In severe sepsis, an increase in S100B does not allow the physicians to distinguish patients with severe impairment of consciousness from those with milder derangements or to prognosticate neurological recovery.

Answer: no

Question: Question: Does kCC2 expression supersede NKCC1 in mature fiber cells in mouse and rabbit lenses?
Answer: NKCC1 in peripheral elongating fiber cells is superseded by KCC2 expression in interior mature fiber cells that also express >20 additional integral GABA biology genes, AMPA/NMDA glutamate receptors, and an array of accessory proteins that together underlie morphogenesis in neurons. The present findings provide further evidence that this fundamental neuronal regulation is extensively conserved in lens and identify additional parallels in the morphogenetic programs that underlie lens fiber cell and neuronal differentiation and contribute to the development of visual acuity.

Answer:
yes
