RIP-MD: a tool to study residue interaction networks in protein molecular dynamics
(PEERJ INC, 2018)
Protein structure is not static; residues undergo conformational rearrangements and, in doing so, create, stabilize or break non-covalent interactions. Molecular dynamics (MD) is a technique used to simulate these movements ...
Signal peptide recognition in Trypanosoma cruzi GP82 adhesin relies on its localization at protein N-terminus
(NATURE PUBLISHING GROUP, 2019)
Trypanosoma cruzi, the causative agent of Chagas disease, has a dense coat of GPI-anchored virulence factors. T. cruzi GPI-anchored adhesin GP82 is encoded by a repertoire of transcripts containing several in-frame initiation ...
Identification and Unusual Properties of the Master Regulator FNR in the Extreme Acidophile Acidithiobacillus ferrooxidans
(FRONTIERS MEDIA SA, 2019)
The ability to conserve energy in the presence or absence of oxygen provides a metabolic versatility that confers an advantage in natural ecosystems. The switch between alternative electron transport systems is controlled ...
SMZ/SNZ and gibberellin signaling are required for nitrate-elicited delay of flowering time in Arabidopsis thaliana
(OXFORD UNIV PRESS, 2018)
The reproductive success of plants largely depends on the correct programming of developmental phase transitions, particularly the shift from vegetative to reproductive growth. The timing of this transition is finely ...
In-Silico Design, Synthesis and Evaluation of a Nanostructured Hydrogel as a Dimethoate Removal Agent
(Chile. Universidad Mayor, 2018-01-04)
This study describes the in-silico design, synthesis, and evaluation of a cross-linked PVA hydrogel (CLPH) for the absorption of organophosphorus pesticide dimethoate from aqueous solutions. The crosslinking effectiveness ...
Relationship between photo-physical and electrochemical properties of D--A compounds regarding solar cell applications. 1. Substituent type effect in photovoltaic performance
(SPRINGER, 2019)
Studying the electrochemical characteristics is an important step for determining interactions between molecules and the chemical environment. Moreover, the electrochemical evaluation of dyes is highly needed to establish ...
Tuning the structure and magnetic behavior of Ni-Ir-based nanoparticles in ionic liquids
(ROYAL SOC CHEMISTRY, 2018)
We report on a simple preparation of extremely small diameter (ca. 2 nm) Ni-Ir-based NPs using Ni(COD)(2) and [Ir(COD)OCH3](2) in 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (BMImNTf(2)). The prepared NPs ...
Toward Controlled Morphology of FeCu Nanoparticles: Cu Concentration and Size Effects
(AMER CHEMICAL SOC, 2018)
Bimetallic nanoparticles (NPs) can be tailored by varying the concentration of their constituent elements, resulting in novel structures and/or configurations, leading to interesting electronic, mechanical, and chemical ...
Simple voltammetric analyses of ochratoxin A in food samples using highly-stable and anti-fouling black phosphorene nanosensor
(PERGAMON-ELSEVIER SCIENCE LTD, 2018)
There are few reports on the electrochemical detection of ochratoxin A (OTA) using chemically modified electrode owing to the OTA poor electrochemical activity and strong fouling effect towards electrode surface. In this ...
Growth of Ni nanoclusters on irradiated graphene: a molecular dynamics study
(ROYAL SOC CHEMISTRY, 2018)
We studied the soft landing of Ni atoms on a previously damaged graphene sheet by means of molecular dynamics simulations. We found a monotonic decrease of the cluster frequency as a function of its size, but few big ...
