Percutaneous transapical access for pulmonary vein mapping and ablation in a porcine model with a new high-density electroanatomical mapping system.

International journal of clinical and experimental medicine

J Atr Fibrillation. 2016 Oct 31;9(3):1418. doi: 10.4022/jafib.1418. eCollection 2016.

Pulmonary vein (PV) stenosis is a known complication of PV isolation procedures for atrial fibrillation. We describe in this report a case of emergency covered stent implantation for rupture of a PV after balloon angioplasty for postinterventional PV stenosis...

Intramuscular Priming and Intranasal Boosting Induce Strong Genital Immunity Through Secretory IgA in Minipigs Infected with Chlamydia trachomatis.

Front Immunol. 2015 Dec 16;6:628. doi: 10.3389/fimmu.2015.00628. eCollection 2015.

International efforts in developing a vaccine against Chlamydia trachomatis have highlighted the need for novel immunization strategies for the induction of genital immunity. In this study, we evaluated an intramuscular (IM) prime/intranasal boost vaccination strategy in a Göttingen Minipig...

First Cr(III)-SNS complexes and their use as highly efficient catalysts for the trimerization of ethylene to 1-hexene.

Journal of the American Chemical Society

McGuinness DS, Wasserscheid P, Keim W, Morgan D, Dixon JT, Bollmann A, Maumela H, Hess F, Englert U.
PMID: 12720428
J Am Chem Soc. 2003 May 07;125(18):5272-3. doi: 10.1021/ja034752f.

Cr(III) complexes of tridentate SNS ligands have been prepared and evaluated as catalysts for ethylene trimerization, with several giving very high activity and excellent selectivity toward 1-hexene when activated with methylaluminoxane. The new complexes illustrate the potential of sulfur-based...

Single-file diffusion of atomic and colloidal systems: asymptotic laws.

We present a general derivation of the non-Fickian behavior for the self-diffusion of identically interacting particle systems with excluded mutual passage. We show that the conditional probability distribution of finding a particle at position x(t) after time t, when...

Dynamic scaling and freezing criteria in quasi-two-dimensional dispersions.

We report on a Brownian dynamics simulation study of quasi-two-dimensional dispersions of colloidal spheres interacting by long-range electrostatic and dipolar magnetic forces. The calculated dynamic correlation functions are shown to obey dynamic scaling in terms of a characteristic relaxation...
