CPG graphs : Some Structural and Hardness Results

Champseix, Nicolas ; Galby, Esther ; Munaro, Andrea ; Ries, Bernard

In: Discrete Applied Mathematics, 2021, vol. 290, p. 17-35

In this paper we continue the systematic study of Contact graphs of Paths on a Grid (CPG graphs) initiated in Deniz et al. (2018). A CPG graph is a graph for which there exists a collection of pairwise interiorly disjoint paths on a grid in one-to-one correspondence with its vertex set such that two vertices are adjacent if and only if the corresponding paths touch at a grid-point. If every...

Optical and theoretical study of strand recognition by nucleic acid probes

Domljanovic, Ivana ; Taskova, Maria ; Miranda, Pâmella ; Weber, Gerald ; Astakhova, Kira

In: Communications Chemistry, 2020, vol. 3, no. 1, p. 111

Detection of nucleic acids is crucial to the study of their basic properties and consequently to applying this knowledge to the determination of pathologies such as cancer. In this work, our goal is to determine new trends for creating diagnostic tools for cancer driver mutations. Herein, we study a library of natural and modified oligonucleotide duplexes by a combination of optical and...

Lipid nanoparticles biocompatibility and cellular uptake in a 3D human lung model

Magalhães, Joana ; Pinheiro, Marina ; Drasler, Barbara ; Septiadi, Dedy ; Petri-Fink, Alke ; Santos, Susana G ; Rothen-Rutishauser, Barbara ; Reis, Salette

In: Nanomedicine, 2020, vol. 15, no. 3, p. 259–271

Aim: Design nanostructured lipid carriers (NLC) to facilitate drug delivery to tuberculosis-infected areas, exploiting macrophage mannose receptors and assess their uptake in a 3D human lung model. Materials & methods: NLCs and mannosylated-NLCs were synthetized and characterized. Their uptake and biocompatibility were tested in a 3D human lung model. Results: The formulations have...

Diagram, valence-to-core, and hypersatellite Kβ X-ray transitions in metallic chromium

Zeeshan, Faisal ; Hoszowska, Joanna ; Dousse, Jean-Claude ; Sokaras, Dimosthenis ; Weng, Tsu-Chien ; Alonso-Mori, Roberto ; Kavčič, Matjaz ; Guerra, Mauro ; Sampaio, Jorge Miguel ; Parente, Fernando ; Indelicato, Paul ; Marques, José Pires ; Santos, José Paulo

In: X-Ray Spectrometry, 2019, vol. 48, no. 5, p. 351–359

We report on measurements of the Kβ diagram, valence‐to‐core (VtC), and hypersatellite X‐ray spectra induced in metallic Cr by photon single and double K‐shell ionization. The experiment was carried out at the Stanford Synchrotron Radiation Lightsource using the seven‐crystal Johann‐type hard X‐ray spectrometer of the beamline 6‐2. For the Kβ diagram and VtC transitions, the...
