[EX Q]: Question: Is s100A8 a novel therapeutic target for anaplastic thyroid carcinoma?
Answer: These findings establish a novel role for S100A8 in the promoting and enhancing of ATC progression. They further suggest that the inhibition of S100A8 could represent a relevant therapeutic target, with the potential of enabling a more effective treatment path for this deadly disease.
[EX A]: yes

[EX Q]: Question: Are arterial stiffness and pulse wave reflection increased in patients suffering from severe periodontitis?
Answer: The results of this study confirm the association between periodontal inflammation and increased cardiovascular risk shown by impaired vascular health in case of severe periodontitis. As impaired vascular health is a common finding in patients suffering from severe periodontal disease a concomitant routine cardiovascular evaluation may be advised.
[EX A]: yes

[EX Q]: Question: Does unilateral Hypothalamus Inactivation prevent PTZ Kindling Development through Hippocampal Orexin Receptor 1 Modulation?
Answer: It is concluded that LHA inactivation prevented kindling development probably through orexin receptor antagonism. CSF orexin probably acts as an inhibitory step on convulsive intensity through another unknown process.
[EX A]:
yes
