Adsorption and Detection of DNA Dendrimers at Carbon Electrodes

1998

Made available in DSpace on 2022-04-28T19:53:27Z (GMT). No. of bitstreams: 0 Previous issue date: 1998-01-01 Dendritic nucleic acids are highly branched and ordered molecular structures, possessing numerous single-stranded oligonucleotide arms, which hold great promise for enhancing the sensitivity of DNA biosensors. This article evaluates the interfacial behavior and redox activity of nucleic acid dendrimers at carbon paste electrodes, in comparison to DNA. Factors influencing the adsorption behavior, including the adsorption potential and time, solution conditions, or dendrimer concentration, are explored. The strong adsorption at the anodically pretreated carbon surface is exploited for …

Simultaneous homogeneous immunoassay of phenytoin and phenobarbital using a Nafion-loaded carbon paste electrode and two redox cationic labels

1997

Abstract The dual-analyte homogeneous immunoassay of two antiepileptic drugs was carried out simultaneously at physiological pH by square-wave voltammetry at a Nafion-loaded carbon paste electrode. Phenobarbital (PB) and phenytoin (DPH) were labeled by a cobaltocenium salt (Cc+) and a ferroceneammonium salt (N+Fc), respectively, and the corresponding standard redox potentials were −1.05 V and 0.26 V. Detection limits of 0.25 and 0.2 μM were achieved for PB-Cc+ and DPH-N+Fc (S/N = 3) after a 5-minute accumulation step, with linear responses over the 0.25–5 and 0.2–5 μM ranges, respectively. The relative standard deviation was evaluated to be ≥ 11% for 1 μM of each labeled drug. The separate,…

Effect of Supplementation with Wheat Bran Aqueous Extracts Obtained by Ultrasound-Assisted Technologies on the Sensory Properties and the Antioxidant…

2015

Phenolic compounds have antioxidant properties and activate endogenous detoxification defense systems able to scavenge the reactive species of oxygen. The external layers of wheat caryopsis, largely constituting by-products of the milling industry such as bran and various middlings, contain relevant amounts of phenolic compounds. The aim of the research has been to evaluate the effect of supplementation with wheat bran aqueous extracts, obtained by ultrasound-assisted technologies, on the sensory properties and antioxidant activity of dry pasta. The HPLC-DAD characterization of the extract evidenced the presence of ferulic and p-coumaric acids. The supplemented pasta showed significantly h…

Posługa Kościoła wobec młodzieży na przykładzie diecezji opolskiej

2019

Synod Biskupów dotyczący duszpasterstwa młodzieży, który odbył się w 2018 roku, zauważa, iż posługa pastoralna prowadzona wśród ludzi młodych powinna odbywać się przede wszystkim na poziomie parafii w ramach duszpasterstwa zwyczajnego. Jednak działalność zbawcza Kościoła wśród młodzieży wymaga także obecności elementów duszpasterstwa nadzwyczajnego, co ma dokonywać się poprzez odpowiednie przygotowanie samego duszpasterza i pomagających mu animatorów. Takie działanie może przyczynić się do efektywności prowadzonych działań pastoralnych. Niewątpliwie konieczne wydają się również: wizja, strategia prowadzenia duszpasterstwa na szczeblu diecezji, dekanatu i parafii, a także znajomość kondycji …

Split-ticket voting in German Federal elections, 1953–90: an example of sophisticated balloting?

1999

Abstract Though the German electoral system has provided the opportunity of split-ticket voting since 1953, until now there has only been mere speculation concerning the rationality of ticket-splitting. In this paper we examine the rationality thesis empirically, using data provided by the official representative electoral statistics of the Federal Republic. Modifying the Downsian notion of rational voting, rational ticket-splitting is defined in terms of coalition building and of voters' expectations of the electoral success of candidates and parties. Applying this conceptual framework, it will be shown that the combinations of first and second votes actually chosen by a majority of the Ge…
