“Objective: We sought to determine the effects

of open (O) and closed (C) cell stents on the size and number of embolic particles generated during carotid artery stenting (CAS) and assess the impact on outcome.

Methods: Embolic debris from carotid filters after CAS was analyzed using photomicroscopy and imaging software. Patient comorbidities, preoperative cerebrovascular symptoms, stent type, and outcomes (perioperative major adverse events) were examined.

Results: Carotid filters from 173 consecutive CAS procedures (O, 125 and C, 48) were reviewed. The mean age was 70.9 +/- 9.2 years; 58% were men. Mean stenosis was 88.2% +/- 8.1%; 36.6% had neurological symptoms preprocedurally. There was no difference in preoperative symptoms between the two groups

(O, 38.7% vs C, 31.3%; P = not significant [NS]). However, closed cell stent use was associated with higher degree of stenosis (O, 87.2% +/- 8.0% vs C, 90.6% A-1210477 mw +/- 7.8%; P = .01), an older age (O, 70.0 +/- 8.6 years vs C, 73.4 +/- 10.2 years; P = .03), and peripheral arterial disease (21.1% vs 43.5%; P = .01). A larger mean particle size was observed in patients treated with open cell stents compared to closed cell stents (O, 416.5 +/- 335.7 mu m vs C, 301.1 +/- 251.3 mu m; P = .03). There was no significant difference in the total number of particles (O, 13.8 +/- 21.5 vs C, 17.6 +/- 19.9; Flavopiridol (Alvocidib) P = NS), periprocedural stroke (P = NS), and major adverse events between the two groups (P = NS).

Conclusions: Open cell stents are associated with a larger mean particle size compared to closed cell stents. No impact on procedural outcomes based on stent type was observed. (J Vasc Surg 2012;56:89-95.)”

Bacillus fragment, belonging to a class of high-fidelity polymerases, demonstrates high processivity (adding similar to 115 bases per DNA binding event) and exceptional accuracy (1 error in 10(6) nucleotide incorporations) during DNA replication. We present analysis of structural rearrangements and energetics just before and during the chemical step (phosphodiester bond formation) using a combination of classical molecular dynamics, mixed quantum mechanics molecular mechanics simulations, and free energy computations. We find that the reaction is associative, proceeding via the two-metal-ion mechanism, and requiring the proton on the terminal primer O3′ to transfer to the pyrophosphate tail of the incoming nucleotide before the formation of the pentacovalent transition state.
