[EX A]: no

[EX Q]: Question: Do integrin-associated complexes form hierarchically with variable stoichiometry in nascent adhesions?
Answer: These observations suggest a working model for NA assembly whereby transient α-actinin-integrin complexes help nucleate NAs within the lamellipodium. Subsequently, integrin complexes containing kindlin, but not talin, emerge. Once NAs have formed, myosin II activity promotes talin association with the integrin-kindlin complex in a stoichiometry consistent with each talin molecule linking two integrin-kindlin complexes.
[EX A]: yes

[EX Q]: Question: Does gastroprotective effect of the iridoid fraction from Barleria prionitis leave on experimentally-induced gastric ulceration?
Answer: The data shows that the iridoid fraction from BPE possesses anti-ulcerogenic and antioxidant potential.
[EX A]:
yes
