[EX Q]: Question: Is 14-3-3η a novel mediator associated with the pathogenesis of rheumatoid arthritis and joint damage?
Answer: Extracellular 14-3-3η activates key signalling cascades and induces factors associated with the pathogenesis of RA at concentrations found in patients with RA, and its expression is higher in patients with radiographic damage and RA progression.
[EX A]: yes

[EX Q]: Question: Do tECPR2 mutations cause a new subtype of familial dysautonomia like hereditary sensory autonomic neuropathy with intellectual disability?
Answer: We suggest that the disease should therefore be classified as a new subtype of hereditary sensory-autonomic neuropathy. The discovery of additional mutations in non-Bukharian patients implies that this disease might be more common than previously appreciated and should therefore be considered in undiagnosed cases of intellectual disability with autonomic features and respiratory symptoms regardless of demographic origin.
[EX A]: yes

[EX Q]: Question: Does off-pump coronary artery bypass surgery reduce gastrointestinal complications?
Answer: Our study suggests that off-pump and on-pump techniques are similar in the rates of GI complications. We suggest that a properly designed randomized control trial is needed to verify our findings.
[EX A]:
no
