PROBLEM: Question: Is the absolute nucleated red blood cell ( aNRBC ) count at birth an indicator for retinopathy of prematurity ( ROP )?
Answer: We are unable to support the previously reported relationship of aNRBCs with ROP. Our population was three times larger, had higher aNRBCs and less retinopathy than previously reported. A biological principle of cause and effect or predisposition to ROP as reflected by aNRBCs should have been easier for us to demonstrate, if it existed.

SOLUTION: no

PROBLEM: Question: Are common genetic variants related to vitamin D status associated with esophageal squamous cell carcinoma risk in China?

SOLUTION: no

PROBLEM: Question: Does tetanus toxin reduce local and descending regulation of the H-reflex?
Answer: Tetanus toxin increased the amplitude of the Hwave and reduced the normal depression of H-wave amplitude that is associated with closely timed stimuli, two phenomena that could contribute to hyperactivity of the stretch reflex.

SOLUTION:
yes
