New derivatives of piperidino[4,5-d]dioxane and 3-oxa-7-bicyclo[3.3.1]nonane were obtained by the oxidatively catalysed condensation of 4-aryl-1,2,3,6-tetrahydropyridines with formaldehyde. The direction of this reaction is sharply altered in the presence of manganese dioxide to give 6-oxa-2-azabicylo[3.2.1]octan-4-one — the product of the oxidative condensation of a new type. 相似文献

Dynamical behaviour and exact solutions of thirteenth order derivative nonlinear Schr\"{o}dinger equation 下载免费PDF全文
In this paper, we considered the model of the thirteenth order derivatives of nonlinear Schr\"{o}dinger equations. It is shown that a wave packet ansatz inserted into these equations leads to an integrable Hamiltonian dynamical sub-system. By using bifurcation theory of planar dynamical systems, in different parametric regions, we determined the phase portraits. In each of these parametric regions we obtain possible exact explicit parametric representation of the traveling wave solutions corresponding to homoclinic, hetroclinic and periodic orbits. 相似文献

Existence of kink and unbounded traveling wave solutions of the Casimir equation for the Ito system 下载免费PDF全文
This paper study the traveling wave solutions of the Casimir equation for the Ito system. Since the derivative function of the wave function is a solution of a planar dynamical system, from which the exact parametric representations of solutions and bifurcations of phase portraits can be obtained. Thus, we show that corresponding to the compacton solutions of the derivative function system, there exist uncountably infinite kink wave solutions of the wave equation. Corresponding to the positive or negative periodic solutions and homoclinic solutions of the derivative function system, there exist unbounded wave solutions of the wave function equation. 相似文献

We report the development of a novel quartz crystal microbalance immunosensor with the simultaneous measurement of resonance
frequency and motional resistance for the detection of antibodies to double-stranded DNA (dsDNA). The immobilization of poly(l-lysine) and subsequent complexation with DNA resulted in formation of a sensitive dsDNA-containing nanofilm on the surface
of a gold electrode. Atomic force microscopy has been applied for the characterization of a poly(l-lysine)–DNA film. After the blocking with bovine serum albumin, the immunosensor in flow-injection mode was used to detect
the antibodies to dsDNA in purified protein solutions of antibodies to dsDNA and to single-stranded DNA, monoclonal human
immunoglobulin G, DNase I and in blood serum of patients with bronchial asthma and systemic lupus erythematosus. Experimental
results indicate high sensitivity and selectivity of the immunosensor.

The use of inorganic nanoparticles (NPs) as vectors for the delivery of oligonucleotides for in vitro and in vivo applications is rapidly gaining momentum. Some of the reasons making them especially good candidates for this purpose are their ease of synthesis in a range of sizes and surface coatings, their propensity to penetrate cell membranes, their stability and biocompatibility, and their unique size-dependent physical properties that impart additional diagnostic and therapeutic tools. Notwithstanding these notable attributes, a major obstacle to their practical use is given by the typically low oligonucleotide loading levels attainable through conventional bioconjugation procedures. This shortcoming is especially worrisome as toxicity concerns have been associated with codelivery of NPs. In this paper we are analytically analyzing the formation of electrostatic complexes between negatively charged ssDNA and positively charged iron oxide nanoparticles (SPIO-NP) with the purpose of identifying the optimal conditions leading to stable formulations at high oligo loading levels. The formation and loading levels of ssDNA:SPIO-NP complexes have been investigated at different oligo:NP ratios and under different ionic strengths through dynamic light scattering, fluorescence quenching experiments, and pull-down assays. Through these studies we have identified optimal conditions for attaining maximal oligo loading levels, and we are proposing a simple model to explain an unusual behavior observed in the formation of the complexes. Finally, we introduce an alternative loading method relying on the electrostatic coloading of an oligo sequence in the presence of a negatively charged PEGylated block copolymer, yielding very stable and high loading PEGylated ssDNA:SPIO-NPs. The findings that we are reporting are of general validity, and similar conditions could be easily translated to the electrostatic formation of ssDNA:NP complexes consisting of different NP materials and sizes. 相似文献

We report on a study of the proton induced hyperon production reactions. We discuss the theoretical efforts made towards understanding
the existing data and the uncertainties involved in the calculations. Our recent calculations of the missing mass spectra
for the pp → K
+ Λp reaction which involve a proper coupled channel treatment of the final state Λp interaction are presented. Significant differences in the results using different models of the hyperon-nucleon interaction
are found. 相似文献

Oxidation of 4-phenyl-, 4-(4-pyridyl)-, and 4-phenethenyl-1,2,3,6-tetrahydropyridines with potassium permanganate can stop at the stage of the introduction of an oxo group into the allyl C(2) position of the piperideine fragment. In contrast to their precursors, 4-aryltetrahydropyridin-2-ones obtained in this way can be converted to 3,4-dihydroxy-2-oxopiperidines under Wagner reaction conditions. 相似文献

We have investigated the fast ethylamine gas sensing of 2-chloro-3,5-dinitrobenzotrifluoride(CDBF) loaded poly(acrylonitrile) nanofiber based on an intermolecular charge-transfer complexation.Reversible response and recovery were achieved using alternating gas exposure.This system shows a fast ethylamine gas sensing within 0.4 s. 相似文献
