[Q]: Question: Does gender difference affect the outcomes of eccentric rotational acetabular osteotomy used in hip dysplasia?
Answer: The mean operative time and the blood loss were not significantly different between male and female patients. Postoperative CE angle tended to be smaller in male than female patients. The survival rate was not significantly different between males and females. Gender difference did not affect the clinical outcomes of ERAO in patients with hip dysplasia.
[A]: no


[Q]: Question: Is arthrogenic muscle inhibition present in the limb contralateral to a simulated knee joint effusion?
Answer: Knee joint effusion results in ipsilateral but not contralateral impairment of quadriceps function. Rehabilitation protocols after knee joint injury should focus on ipsilateral neuromuscular and mechanical alterations that occur as the result of joint damage.
[A]: no


[Q]: Question: Does nitric oxide exert protective effects against bleomycin-induced pulmonary fibrosis in mice?
Answer: These results provide the first direct evidence that a lack of all three NOS isoforms led to a deterioration of pulmonary fibrosis in a BLM-treated murine model. We speculate that the entire endogenous NO and NOS system plays an important protective role in the pathogenesis of pulmonary fibrosis.
[A]:
yes
