Amphiphiles are synthetic or natural molecules with the ability to self-assemble into a wide variety of structures including micelles, vesicles, nanotubes, nanofibers, and lamellae. Self-assembly processes amphiphiles have been widely used mimic biological systems, such as assembly lipids proteins, while their integrated actions allow performance highly specific cellular functions which has paved way for bottom-up bionanotechnology. While self-assembly attracted considerable attention...
Results of Raman scattering measurements performed on aqueous solutions the homologous disaccharides (trehalose, maltose, and sucrose) are reported. To get some insight into effects hydrogen bond network water, to clarify reasons that make trehalose most effective in protecting organisms from dehydration freezing, we investigate intramolecular OH stretching mode. carry out this study, two different approaches employed: namely, a decomposition isotropic spectra an “open” “closed”...
Depression is a recurring and life-threatening illness that affects up to 120 million people worldwide. In the present study, we show chronic social defeat stress, an ethologically validated model of depression in mice, increases SIRT1 levels nucleus accumbens (NAc), key brain reward region. Increases SIRT1, well characterized class III histone deacetylase, after suggest role for this enzyme mediating depression-like behaviors. When resveratrol, pharmacological activator was directly infused...
This study focuses on the experimental thermal response analysis of a newly synthesized nanocomposite, denoted as HAP/PEG, containing Hydroxyapatite-alt-Polyethylene Glycol. Complementary data obtained from density functional theory (DFT) studies afford insights into structural and optoelectronic properties nanocomposite using 6-31 g (d, p) LanL2DZ basis sets in gas phase water. Reduced gradient used to identify non-covalent interaction (RDG-NCI). Intermolecular interactions were quantified...
We report viscosity and compressibility measurements of trehalose, maltose, sucrose aqueous solutions at different concentration temperature values. What emerges from the dependence is that in comparison to maltose sucrose, shows a higher interaction strength with water, which gives rise greater value hydration number throughout investigated range. Furthermore, reveal high values, trehalose "stronger" kinetic character than other disaccharides, namely, lower structural sensitivity changes...
Despite recent extensive efforts, the nature of dynamics biological macromolecules still remains unclear. In particular, contradicting models have been proposed for explaining temperature behavior mean square displacement, MSD, and system relaxation time, τ. To solve this puzzle, different neutron scattering experiments with instrumental energy resolutions were performed on dry hydrated lysozyme. The obtained results show that so called dynamical transition: (i) is a finite resolution...
Experimental findings obtained by FTIR and Raman spectroscopies on montmorillonite-water mixtures at three concentration values are presented. To get some insight into the hydrogen bond network of water within montmorillonite network, spectra have been collected as a function time then analyzed following two complementary approaches: An analysis intramolecular OH stretching mode in spectral range 2700-3900 cm-1 terms Gaussian components, an same wavelet cross-correlation. The investigations...
The topic dealt with in this paper concerns an experimental study, performed by means of ultrasonic techniques, on aqueous solutions α,α-trehalose, effective bioprotector against dehydration. velocity and density data show that, these solutions, the mixing process is not ideal. behavior excess compressibility as a function concentration can be interpreted supposing that α,α-trehalose molecules form intramolecular hydrogen bonds folding over at high concentration. When water are added, they...
Abstract Biological effects of man‐made electromagnetic fields (EMFs) have been studied so far by experimental approaches exposing animals and cell cultures to EMFs. However, the evidence for toxicity induced static magnetic field (SMF) is still uncertain. We investigated produced exposure human SH‐SY5Y neuronal‐like cells a uniform at intensities 2.2 mT, which less than recommended public limits set International Commission on Non‐Ionizing Radiation Protection (ICNIRP). A decrease membrane...
Exopolysaccharide (EPS) production represents an adaptive strategy developed by extremophiles to cope with environmental stresses. The EPS-producing Bacillus licheniformis B3-15, of shallow marine vent origin (Vulcano Island, Italy), was previously reported as tolerant arsenate (AsV). In this study, we evaluated: (i) the increasing EPS B3-15 in novel SG17 medium; (ii) arsenic absorption capacity mass spectroscopy; (iii) functional groups interacting As ATR-FTIR and (iv) ability prevent...
In this work, we use a combination of dispersion-corrected density functional theory (DFT-D3) and the TiberCAD framework for first time to investigate newly designed synthesized class (C6H10N2)[CuCl4] 2D-type perovskite. The inter- intra-atomic reorganization in crystal packing type interaction forming active area have been discussed via Hirshfeld surface (HS) analyses. A distinct charge transfer from CuCl4 [C6H10N2] is identified by frontier molecular orbitals (FMOs) states (DOS). This...
To study the hydration effect of poly(ethylene glycol) (PEG) and its dependence on molecular weight, we report viscosity, compressibility, quasi elastic light-scattering measurements aqueous solutions PEG with different mean Mw, at concentration temperature values. In particular, ultrasonic technique allows to evaluate number for samples polymerization degrees. The values deduced by are then compared those from viscosity data following Linow Philipp's model. PCS obtain information...
