Input: Consider Input: Question: Does bisphenol A increase atherosclerosis in pregnane X receptor-humanized ApoE deficient mice?
Answer: These findings identify a molecular mechanism that could link BPA exposure to increased risk of CVD in exposed individuals. PXR is therefore a relevant target for future risk assessment of BPA and related environmental chemicals in humans.

Output: yes


Input: Consider Input: Question: Is pseudomonas aeruginosa in CF and non-CF homes found predominantly in drains?
Answer: These findings implicate drains as important potential sources of P. aeruginosa infection. They suggest that maximizing P. aeruginosa control efforts for drains would reduce exposure with minimal extra burden to CF patients and families.

Output: yes


Input: Consider Input: Question: Is leg extension power a pre-disaster modifiable risk factor for post-traumatic stress disorder among survivors of the Great East Japan Earthquake : a retrospective cohort study?
Answer: Leg extension power is a potentially modifiable pre-disaster risk factor among men for attenuating the severity of PTSD symptoms associated with great disasters such as the Great East Japan Earthquake among men.


Output: yes
