#1
Liliana Ironi, Ettore Lanzarone
Computational and mathematical models have significantly contributed to the rapid progress in the study of gene regulatory networks (GRN), but researchers still lack a reliable model-based framework for computer-aided analysis and design. Such tool should both reveal the relation between network structure and dynamics and find parameter values and/or constraints that enable the simulated dynamics to reproduce specific behaviors. This paper addresses these issues and proposes a computational framework that facilitates network analysis or design...

Recently, great attention has been paid to the identification and prediction of the androgen disrupting potencies of polybrominated diphenyl ethers (PBDEs). However, few existing models can discriminate active and inactive compounds, which make the quantitative prediction process including the quantitative structure-activity relationship (QSAR) technique unreliable. In this study, different grouping methods were investigated and compared for qualitative identification, including molecular docking and molecular dynamics simulations (MD)...

Soil-derived dissolved organic matter (DOM) has a major influence in biogeochemical processes related to contaminant dynamics and greenhouse gas emissions, due to its reactivity and its bridging role between the soil and aquatic systems. Within the Three Gorges Reservoir (TGR, China) area, an extensive water-fluctuation zone periodically submerges the surrounding soils. Here we report a characterization study of soil-derived DOM across the TGR areas, using elemental and optical analysis, infrared spectroscopy (FTIR), pyrolysis-GC-MS (Py-GC-MS) and thermally assisted hydrolysis and methylation (THM-GC-MS)...

Multi-morbidity and polypharmacy are common in older patients and increase their susceptibility to adverse drug events and hospitalizations. Rational drug prescription is critical, however, little is known about physicians' perspectives on how to prescribe drugs for older patients. The aim of this study was to explore physicians' approach to prescribe drugs to older patients, including identifying the drugs that physicians perceive to be risk drugs for older patients and comparing them with established lists of potentially inappropriate medications...

Deposition on contact lenses (CLs) starts quickly after their application to the ocular surface. Deposits may be composed of tear film components or other extraneous substances. These deposits have been related to various adverse conditions of the eye, leading to reduced biocompatibility between the CLs and the ocular surface. Analysis of these deposits is essential to better elucidate the relationship between these deposits and their adverse reactions so that better methods of increasing biocompatibility can be developed...
