Telescopic catheter‐in‐long sheath and parallel to a stiff guide wire technique for complex pulmonary artery anatomy
Authors: Butera Gianfranco , Hassan Eman , MacDonald Simon T. 
Published: March 2012

AbstractSelective catheterization and procedures in pulmonary arteries may be very challenging. We developed a technique in which an extra‐stiff guide wire was placed in a pulmonary artery. Across it a long sheath was placed proximally or controlateral to the lesion to be treated. An angiographic catheter was then placed parallel to the guide wire in a telescopic way within the long sheath. This system facilitated greater stability, allowing fine tuning of catheter position to reach and treat the target lesion. Here, we present five cases in whom this technique was used; a patient with multiple arteriovenous fistulas in a difficult to reach area and four subjects with complex pulmonary artery stenoses. © 2012 Wiley Periodicals, Inc.

AbstractBackgroundAlthough embolic protection devices (EPDs) have been shown to be beneficial in saphenous vein graft (SVG) lesions, their role in the subgroup of ostial SVG lesions has received limited study.MethodsThe coronary angiograms and procedural outcomes of 109 patients undergoing stenting of 113 ostial SVG lesions were retrospectively reviewed to determine the frequency of EPD use and the periprocedural outcomes.ResultsNinety‐eight (87%) of the 113 lesions were suitable for EPD use, that was used in 70 lesions (71%). A Filterwire (Boston Scientific) or a SPIDER (ev3) filter were used in 54 (77%) and 16 (23%) of lesions, respectively. Difficulty retrieving the filter post stenting was encountered in eight lesions (11%) and led to stent thrombosis causing cardiac arrest in one patient (1%). Angiographic success was achieved in 111 (98%) of 113 lesions.ConclusionsEPDs can be utilized in the majority of ostial SVG lesions, but in 11% of cases filter retrieval can be challenging and may rarely (in approximately 1%) lead to a significant complication. © 2012 Wiley Periodicals, Inc.

AbstractObjectivesTo study the early and mid‐term vascular complications of axillary artery catheterization in children <2 years by clinical and ultrasound examination.BackgroundFemoral arterial access for cardiac catheterization in young children is associated with significant morbidity. Early complications of axillary artery catheterization have been reported but no long‐term vascular follow‐up data are available.MethodsProspective case–control study using standard vascular ultrasound techniques to examine the upper limbs in study participants (n = 10).ResultsIn total, 23% of axillary artery catheterizarions (56 procedures in 54 patients) resulted in acute arterial insufficiency requiring heparin. Of the survivors under follow‐up (n = 33), none had symptoms of chronic arterial insufficiency. At a median follow‐up of 8 years postprocedure, three out of the ten study participants had a weak brachial pulse in the test arm but no significant difference in arm measurements. Color Doppler revealed occlusion of the axillary artery in the test arm with collateralization in three patients. The brachial peak systolic velocity (Vmax) was significantly lower in the test arm than the control arm of all the patients with a mean difference of 30 cm/sec (P = 0.007).ConclusionOur study is the first to examine the long‐term vascular sequelae of axillary artery catheterization using ultrasound examination and highlights the importance of careful surveillance of vascular access sites. Although axillary artery cut‐down for cardiac catheterization in infants and young children does not appear to result in clinical signs of chronic arterial insufficiency, we demonstrate clear evidence of flow abnormalities on vascular ultrasound which are of uncertain long‐term significance. © 2012 Wiley Periodicals Inc.
Amplatzer vascular plug for transcatheter closure of persistent unligated vertical vein after repair of infracardiac total anomalous pulmonary venous connection
Authors: Kobayashi Daisuke , Forbes Thomas J. , Delius Ralph E. , Aggarwal Sanjeev 
Published: March 2012

AbstractRepair of total anomalous pulmonary venous connection (TAPVC) involves anastomosing the pulmonary venous confluence with the left atrium and ligating the vertical vein. Sometimes, the vertical vein needs to be left open as a pop off with the idea that it will close over time. Infrequently an unligated vertical vein may remain patent after repair of infaracardiac TAPVC leading to hemodynamic instability. We report an infant in whom an unligated vertical vein remained patent after the repair of infracardiac TAPVC and caused hemodynamically significant left‐to‐right shunting. A successful transcatheter closure of persistent patent unligated vertical vein was performed using the Amplatzer Vascular Plug‐I device. © 2012 Wiley Periodicals, Inc.
Ruthenium(II)–Polyimine–Coumarin Light‐Harvesting Molecular Arrays: Design Rationale and Application for Triplet–Triplet‐Annihilation‐Based Upconversion

Published: March 2012

AbstractRuII–bis‐pyridine complexes typically absorb below 450 nm in the UV spectrum and their molar extinction coefficients are only moderate (ε<16 000 M−1 cm−1). Thus, RuII–polyimine complexes that show intense visible‐light absorptions are of great interest. However, no effective light‐harvesting ruthenium(II)/organic chromophore arrays have been reported. Herein, we report the first visible‐light‐harvesting RuII–coumarin arrays, which absorb at 475 nm (ε up to 63 300 M−1 cm−1, 4‐fold higher than typical RuII–polyimine complexes). The donor excited state in these arrays is efficiently converted into an acceptor excited state (i.e., efficient energy‐transfer) without losses in the phosphorescence quantum yield of the acceptor. Based on steady‐state and time‐resolved spectroscopy and DFT calculations, we proposed a general rule for the design of RuII–polypyridine–chromophore light‐harvesting arrays, which states that the 1IL energy level of the ligand must be close to the respective energy level of the metal‐to‐ligand charge‐transfer (MLCT) states. Lower energy levels of 1IL/3IL than the corresponding 1MLCT/3MLCT states frustrate the cascade energy‐transfer process and, as a result, the harvested light energy cannot be efficiently transferred to the acceptor. We have also demonstrated that the light‐harvesting effect can be used to improve the upconversion quantum yield to 15.2 % (with 9,10‐diphenylanthracene as a triplet‐acceptor/annihilator), compared to the parent complex without the coumarin subunit, which showed an upconversion quantum yield of only 0.95 %.
Cucurbituril‐Modulated Supramolecular Assemblies: From Cyclic Oligomers to Linear Polymers
Authors: Qian Hai , Guo Dong‐Sheng , Liu Yu 
Published: March 2012

AbstractEmploying bis(p‐sulfonatocalix[4]arenes) (bisSC4A) and N′,N′′hexamethylenebis(1‐methyl‐4,4′‐bipyridinium) (HBV4+) as monomer building blocks, the assembly morphologies can be modulated by cucurbit[n]uril (CB[n]) (n=7, 8), achieving the interesting topological conversion from cyclic oligomers to linear polymers. The binary supramolecular assembly fabricated by HBV4+ and bisSC4A units, forms an oligomeric structure, which was characterized by NMR spectroscopy, atomic force microscopy (AFM), transmission electron microscopy (TEM), dynamic light scattering (DLS), isothermal titration calorimetry (ITC), and gel permeation chromatography (GPC) experiments. The ternary supramolecular polymer participated by CB[8] is constructed on the basis of host–guest interactions by bisSC4A and the [2]pseudorotaxane HBV4+@CB[8], which is characterized by means of AFM, DLS, NMR spectroscopy, thermogravimetric analysis (TGA), UV/Vis spectroscopy, and elemental analysis. CB[n] plays vital roles in rigidifying the conformation of HBV4+, and reinforcing the host–guest inclusion of bisSC4A with HBV4+, which prompts the formation of a linear polymer. Moreover, the CB[8]‐participated ternary assembly could disassemble into the molecular loop HBV2+@CB[8] and free bisSC4A after reduction of HBV4+ to HBV2+, whereas the CB[7]‐based assembly remained unchanged after the reduction. CB[8] not only controlled the topological conversion of the supramolecular assemblies, but also improved the redox‐responsive assembly/disassembly property practically.
Remarkable Sensitivity of the Electrochemical Reduction of Benzophenone to Proton Availability in Ionic Liquids
Authors: Zhao Shu‐Feng , Lu Jia‐Xing , Bond Alan M. , Zhang Jie 
Published: March 2012

AbstractThe reduction of benzophenone was investigated in five different ionic liquids by using transient cyclic voltammetry, near steady‐state voltammetry, and numerical simulation. Two reversible, well‐resolved one‐electron‐reduction processes were observed in dry (≤20 ppm water, ca. 1 mM)) 1‐butyl‐1‐methylpyrrolidinium bis(trifluoromethylsulfonyl)imide ([Bmpyrd][NTf2]) and 1‐butyl‐1‐methylpiperidinium bis(trifluoromethylsulfonyl)imide ([Bmpipd][NTf2]), which did not contain any readily available proton source. Upon addition of water, the second process became chemically irreversible and shifted to a more positive potential by approximately 600 mV; moreover, the two reduction processes merged into a single two‐electron proton‐coupled process when about 0.6 M H2O was present. This large dependence of potential on water content, which was not observed in molecular solvents (electrolyte), was explained by a reaction mechanism that incorporated protonation and hydrogen‐bonding interactions of the benzophenone dianion with as many as seven water molecules. In the three imidazolium‐based ionic liquids used herein, the first benzophenone‐reduction process was again reversible, whilst the second reduction process became chemically irreversible owing to the availability of the C2‐H imidazolium protons in these ionic liquids. The reversible potentials for benzophenone reduction were remarkably independent of the identity of the ionic liquids, thereby implying either weak interactions with the ionic liquids or relatively insignificant differences in the levels of ion‐pairing. Thus, the magnitude of the separation of the potentials of the reversible first and irreversible second reduction processes mainly reflected the proton availability from either the ionic liquid itself or from adventitious water. Consequently, voltammetric reduction of benzophenone provides a sensitive tool for the determination of proton availability in ionic liquids.
Double CH Functionalization in Sequential Order: Direct Synthesis of Polycyclic Compounds by a Palladium‐Catalyzed CH Alkenylation–Arylation Cascade

Published: March 2012

AbstractPalladium‐catalyzed cascade CH alkenylation and arylation provides convenient access to polycyclic aromatic compounds. Treatment of 3‐bromoaniline derivatives bearing a bromocinnamyl group on the nitrogen atom with a catalytic amount of [Pd(OAc)2] and PCy3⋅HBF4 in the presence of Cs2CO3 in dioxane affords naphthalene‐fused indole derivatives in good yields. This double cyclization reaction is also applicable to heterocyclic substrates, giving fused indoles containing a heteroaromatic ring such as dibenzofuran, dibenzothiophene, carbazole, indole, or benzofuran through heterocyclic CH arylation. When using a 2,6‐unsubstituted aniline derivative, the first CH arylation preferentially proceeds at the more hindered position of the aniline ring.

Published: March 2012

AbstractGraphene is of considerable interest as a next‐generation semiconductor material to serve as a possible substitute for silicon. For real device applications with complete circuits, effective n‐type graphene field effect transistors (FETs) capable of operating even under atmospheric conditions are necessary. In this study, we investigated n‐type reduced graphene oxide (rGO) FETs of photoactive metal oxides, such as TiO2 and ZnO. These metal oxide doped FETs showed slight n‐type electric properties without irradiation. Under UV light these photoactive materials readily generated electrons and holes, and the generated electrons easily transferred to graphene channels. As a result, the graphene FET showed strong n‐type electric behavior and its drain current was increased. These n‐doping effects showed saturation curves and slowly returned back to their original state in darkness. Finally, the n‐type rGO FET was also highly stable in air due to the use of highly resistant metal oxides and robust graphene as a channel.
