A fumonisins immunosensor based on polyanilino-carbon nanotubes doped with palladium telluride quantum dots
(MDPI, 2015)
An impedimetric immunosensor for fumonisins was developed based on
poly(2,5-dimethoxyaniline)-multi-wall carbon nanotubes doped with palladium telluride
quantum dots onto a glassy carbon surface. The composite was assembled ...
Application on gold nanoparticles-dotted 4-nitrophenylazo graphene in a label-free impedimetric deoxynivalenol immunosensor
(MDPI, 2015)
In this paper, we report a new concept to construct a label-free electrochemical
inhibition-based immunosensor for the detection of the mycotoxin deoxynivalenol (DON)
in cereal samples. The electrochemical impedance ...
An ambusher’s arsenal: chemical crypsis in the puff adder (Bitis arietans)
(The Royal Society, 2015)
Ambush foragers use a hunting strategy that places them at risk of predation by both visual and olfaction-oriented predators. Resulting selective pressures have driven the evolution of impressive visual crypsis in many ...
Acylphloroglucinol derivatives from the South African helichrysum niveum and their biological activities
(MDPI, 2015)
Abstract: Phytochemical investigation of aerial parts of Helichrysum niveum (H. niveum)
using different chromatographic methods including semi-preparative HPLC afforded three
new (1–3) and six known (4–10) acylphloroglucinols ...
Inhibition of oxidative stress and skin aging-related enzymes by prenylated chalcones and other flavonoids from helichrysum teretifolium
(MDPI, 2015)
Ten flavonoid-related structures viz. heliteretifolin (1), isoxanthohumol (2),
2',4',6'-trihydroxy-3'-prenylchalcone (3), isoglabranin (4), glabranin (5), 7-methoxyisoglabranin
(6), quercetin (7), 4'-methoxyquercetin ...
Aptameric recognition-modulated electroactivity of poly(4-styrenesolfonic acid)-doped polyaniline films for single-shot detection of tetrodotoxin
(MDPI, 2015)
The work being reported is the first electrochemical sensor for tetrodotoxin
(TTX). It was developed on a glassy carbon electrodes (C) that was modified with
poly(4-styrenesolfonic acid)-doped polyaniline film (PANI/PSSA). ...
A qualitative study of referring agents’ perceptions of access barriers to inpatient substance abuse treatment centres in the Western Cape
(BioMed Central, 2015)
Background: Despite empirical support for the individual and public health benefits of treating substance use disorders (SUDs) , access to these services is impeded by several barriers. Although many studies on access ...
A detection threshold in the amplitude spectra calculated from Kepler data obtained during K2 mission.
(Oxford University Press, 2015)
We present our analysis of simulated data in order to derive a detection threshold which can
be used in the pre-whitening process of amplitude spectra. In case of ground-based data of
pulsating stars, this threshold is ...
Potential broad spectrum inhibitors of the coronavirus 3CLpro: a virtual screening and structure-based drug design study
(MDPI, 2015)
Human coronaviruses represent a significant disease burden; however, there is currently no antiviral strategy to combat infection. The outbreak of severe acute respiratory syndrome (SARS) in 2003 and Middle East respiratory ...
On the design of smart parking networks in the smart cities: an optimal sensor placement model
(MDPI, 2015)
Smart parking is a typical IoT application that can benefit from advances in
sensor, actuator and RFID technologies to provide many services to its users and parking
owners of a smart city. This paper considers a smart ...
