In order to explore the maternal knowledge, concerns, fears, perceptions and attitude towards diagnosis of HIV in an infant of six weeks old, a qualitative study using semi-structure interviews, which allowed probing questions to clarify responses from participants, was considered the most appropriate design.
Our results show that using imaging channels with elliptically polarized light allows probing subsurface volumes, which are well defined.
Since the identified herpesvirus responsive genetic element is silent in different cell types and cell lines and does not react on proinflammatory stimuli elicited by infection with UV-inactivated virus, even sophisticated experiments could be designed which would allow probing herpesvirus infection in vivo.
This study was carried out by coupling a cyclic voltammetry technique to an optical method which allows the probing of the ionic fluxes in the diffusion layer of an electroactive material (probe beam deflection method).
We demonstrate a strong influence of charged QDs on the conductance of the 2DEG which allows us to probe the tunneling dynamics between the 2DEG and the QDs time resolved.
A corresponding paramagnetic gradient is established, which allows for the probing of peptide and protein membrane insertion.
The plasmon resonance of the nanoparticles is highly wavelength specific, which allows multiplexing multiple probes with distinct excitation spectra [ 11].
Microarrays can be made by presynthesizing the probe molecule and spotting it on a surface using appropriate tethering chemistry, but modern microarrays are made with in situ methods in which the biomolecules are synthesized directly on the substrate from their monomer components, which allows for high probe densities, high uniformity, and high reproducibility.
The high-tech sleuthing, which allows investigators, pictured, to probe behind the wall without having to tamper with the Vasari painting, appears to have paid off, with the discovery of black paint of the type used for the Mona Lisa.
To ensure unambiguous and repeatable measurement results, user-friendly auxiliary tools are used, which allows the operator to probe the measurement points according to existing guidelines and standards.
