Question: Are filaggrin loss-of-function mutations a predisposing factor for atopic dermatitis in an Ishigaki Island under subtropical climate?
Answer: The FLG loss-of-function mutation frequency was not significantly different between the AD and non-AD groups in a cohort of children from Ishigaki Island, which has a subtropical climate, suggesting that FLG loss-of-function mutations are not always a predisposing factor for AD prevalence.

Ex Output:
no


Ex Input:
Question: Does extracellular vesicle-driven information mediate the long-term effects of particulate matter exposure on coagulation and inflammation pathways?
Answer: The study's findings support the hypothesis that adverse cardiovascular and metabolic effects stemming from inhalation exposures in particular to PM metallic component may be mediated by EVmiRNAs that target key factors in the inflammation, coagulation and glucose homeostasis pathways.

Ex Output:

yes
