Pell and associated Pell braid sequences as GCDs of sums of consecutive Pell, balancing, and related numbers
We consider the greatest common divisor (GCD) of all sums of consecutive
terms of a sequence where the terms come from exactly
one of following six well-known sequences' terms: Pell , associated Pell
, balancing , Lucas-balancing , cobalancing , and
Lucas-cobalancing numbers. For each of the six GCDs, we provide closed
forms dependent on . Moreover, each of these closed forms can be realized as
braid sequences of Pell and associated Pell numbers in an intriguing manner. We
end with partial results on GCDs of sums of squared terms and open questions.Comment: 24 pages, Version 3 is the published version in the Journal of

Insulin Induces the Release of Vasodilator Compounds From Platelets by a Nitric Oxide–G Kinase–VAMP-3–dependent Pathway
Insulin-induced vasodilatation is sensitive to nitric oxide (NO) synthase (NOS) inhibitors. However, insulin is unable to relax isolated arteries or to activate endothelial NOS in endothelial cells. Since insulin can enhance platelet endothelial NOS activity, we determined whether insulin-induced vasodilatation can be attributed to a NO-dependent, platelet-mediated process
