Orientation analysis of the beta-sheet structure within films of the established recombinant spider silk protein eADF4(C16) was performed using a concept based on dichroic transmission- and attenuated total reflection-Fourier transform infrared spectroscopy, lineshape analysis, assignment of amide I components to specific vibration modes, and transition dipole moment directions of beta-sheet structures. Based on the experimental dichroic ratio R, the order parameter S of beta-sheet structures was calculated with respect to uniaxial orientation. Films of eADF4(C16) were deposited on untexturized (Si) and unidirectionally scratched silicon substrates (Si-sc) and post-treated with MeOH vapor. Freshly cast thin and thick eADF4(C16) films out of hexafluoroisopropanol featured beta-sheet contents of approximate to 6%, which increased to >30% after MeOH post-treatment in dependence of time. Pseudo-first order folding kinetics were obtained, suggesting a transition from an unfolded to a folded state. In MeOH post-treated thin films with diameters in the nanometer range, a significant orientation of beta-sheets was obtained regardless of the texturization of the silicon substrate (Si, Si-sc). This was rationalized by dichroic ratios of the amide I component at 1696 cm(-1) assigned to the (0, pi) mode of antiparallel beta-sheet structures, whose transition dipole moment M is located in parallel to both beta-sheet plane and chain direction. The calculated high molecular order parameter S approximate to 0.40 suggested vertically (out-of-plane) oriented antiparallel beta-sheet stacks with tilt angles of gamma approximate to 39 degrees to the surface normal. Microscale (thick) films, in contrast, revealed low order parameters S approximate to 0. Scanning force microscopy on thin eADF4 films at silicon substrates showed dewetted polymer film structures rather at the micro-scale. These findings give new insights in the role of the beta-sheet crystallite orientation for the mechanical properties of spider silk materials.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 3184-13-2 is helpful to your research. Safety of H-Orn-OH Hydrochloride.

The present work aims to develop a class of green demulsifiers for effective demulsification process. In this respect, six chitosan-based nonionic surfactants were prepared by chemical modification of chitosan with two aliphatic fatty acids, namely, lauric and stearic. The products were then reacted with polyethylene glycol (PEG 400, 1000 and 2000 g/mol) to produce ether amides surfactants. The prepared surfactants were characterized by IR spectroscopy and their thermal properties were investigated. It was found that the thermal stability of the prepared surfactants increase by increasing the length of PEG chain. Surface properties of the prepared surfactants were calculated through surface tension measurements at different temperatures. Furthermore, the demulsification efficiency of the prepared surfactants was verified under different conditions. Also, maximum water separation was achieved at 45 degrees C, neutral medium and low salt concentration. Viscosity of crude oil before and after demulsification was used as a parameter for demulsification process. Moreover, the demulsification process achieved by the green demulsifiers was monitored by the optical microscope. (C) 2018 Elsevier B.V. All rights reserved.

Activation of lymphocytes during contact with the Epstein-Barr virus (EBV) was studied. The lymphocytes were obtained from patients treated due to the acute phase of infectious mononucleosis in the Jagiellonian University Hospital in Krakow. The changes in the averaged Raman spectra of the lymphocytes during their treatment, on the 1st, 3rd, 5th, 9th and 12th day of hospitalization, were analyzed using the 2D-COS method. The most interesting activation marker was the Raman band at 520 cm(-1) attributed to the formation of immunoglobulins. This band does not occur in the control group samples. The 2D-COS analysis revealed some additional details of lymphocyte activation. In the 2D synchronous maps, the greatest changes occur for auto-peaks at 2929 cm(-1), due to the CH vibrations in the methyl groups of lipids and proteins, at 1638 cm(-1), corresponding to the changes in alpha -helix amide I, 1585 cm(-1) corresponding to nucleic acids and some amino acids, Trp, Phe and Gln, indicating cell remodeling. 2D synchronous maps monitor the formation of a receptor complex, as a subsequent functional lymphocyte maturation. 2D asynchronous maps point to the B-cell development towards immune response, i.e., the formation of immunoglobulins.

Eighteen semen samples from nine Santa Ines rams were cryopreserved in order to study the cryoprotective capacity of dimethylacetamide (DMA) at two concentrations (3% and 6%), and its interaction with trehalose (TRE, 100 mOsmol). A further objective of this study was to evaluate in vivo fertility of ram semen cryopreserved with dimethylacetamide. The control treatment was an extender medium with 6% glycerol (GLY). Five treatments were examined: 6% GLY, 3% DMA, 6% DMA, 3% DMA + TRE, and 6% DMA + TRE. After thawing, the kinetic sperm parameters were analyzed using a computerized system. Sperm viability was observed using a multiple parameter sperm staining with propidium iodide (for plasmatic membrane integrity), JC-1 (for mitochondrial membrane potential), and FITC-PSA (for acrosomal integrity). The isosmotic extender with GLY was the most effective medium for the maintenance of sperm characteristics, compared to extenders containing DMA as cryoprotectant. Regarding fertility, the extender medium with 3% DMA may be a safe alternative for sperm cryopreservation, and does not compromise the fertility rates. The addition of TRE decreased the kinetic sperm parameters; however, a positive effect on the integrity of the plasmatic and acrosomal membranes was observed.

Total synthesis of the proposed structure of baulamycin A was performed. The spectral properties of the synthetic compound differ from those reported for the natural product. On the basis of comprehensive NMR. study; we proposed two other possible structures for natural baulamycin A. Total syntheses of these two substances were performed, which enabled assignment of the correct structure of. baulamycin A. Key features of the convergent and fully stereocontrolled route include Evans Aldol and Brown allylation reactions to construct the left fragment, a prolinol amide-derived alkylation/desymmetrization to install the methyl-substituted centers in the right fragment, and finally, a Carreira alkynylation to join both fragments. In addition, we have determined the inhibitory activities of novel baulamycin A derivatives against the enzyme SbnE. This SAR study provides useful insight into the design of novel SbnE inhibitors that overcome the drug resistance of pathogens, which cause life-threatening infections.

Water flooding is a widely applied method for secondary oil recovery. However, this practice introduces exogenous microorganisms into the oil reservoirs that can have deleterious consequences for the recovery process, such as hydrogen sulfide production and corrosion. Biocide treatments have been used to control harmful microbial activity. However, they tend to has limited efficacy attributed to the selection of resistant bacterial populations. This work combines Metagenomic and metataxonomic approaches to investigate the phylogenetic and functional profile of the produced and injected water from an oil reservoir located in the Andean region. The results reveal a marked dominance of the phylum Proteobacteria in both samples (nearly 99%). While Arcobacter sp. and Pseudomonas balearica were the dominant microbes in the injected water, Marinobacter sp. and Arcobacter sp. were the dominant bacteria in the produced water. Biocide resistance genes coding for efflux pumps and transporters were enriched in the injected water that is treated with a mixture of glutaraldehyde and THPS. The draft genome of the Pseudomonas balearica of the injection water encodes several proteins related to efflux pumps, while the Arcobacter sp. draft genome showed fewer proteins related to these resistance systems. Genome annotation of gene clusters related to secondary metabolism also showed that the Pseudomonas balearica present gene clusters for Amonabactin, Ectoine, and dipeptide N-acetyl glutaminyl glutamine amide (NAGNN), whereas the Arcobacter sp. possess one gene cluster for Bacteriocin.

Azocarboxamides occupy a special place among azo ligands owing to their versatility for metal coordination. Herein ruthenium complexes with two different azocarboxamide ligands that differ in the presence (or not) of a coordinating pyridyl heterocycle are presented. By making full use of the O,N(amide), N(azo), and N(pyridyl) coordinating sites, the first diruthenium complex that is bridged by an azo ligand containing two different binding pockets was obtained. Moreover, it was conclusively proven that, in the mononuclear complexes, oxidation at the ruthenium center leads to a complete change of coordination at the chelating binding pocket. The complexes were characterized by NMR spectroscopy, mass spectrometry, and single-crystal X-ray diffraction. Additionally, the mechanism of the aforementioned redox-triggered change in the chelating binding pocket and the electronic structures of all the complexes were investigated by a combination of electrochemistry, UV/Vis/NIR/EPR spectroelectrochemistry, and DFT calculations. This is first instance in which a redox-driven change in the complete chelating binding pocket has been observed in a ruthenium complex as well as with azo-based ligands. These results thus show the potential of these versatile azocarboxamide ligands to act as redox-driven switches with possible relevance to electrocatalysis.

In phytosynthesis of gold nanoparticles (AuNPs), biomolecules play a vital role in biocapping the surface of particles and generating the electrostatic repulsive forces to inhibit their growth kinetics. However, estimation of bioactive compounds influencing their surface characteristics through formation of electric repulsive forces (Velecdocumentclass), Van der Waals attraction forces (Vvdw) and ultimately hindering their growth is still in the phase of obscurity. Current study, based on surface chemistry approach has been performed for identification of bioactive compounds in Elaeis guineensis leaves (EGL/OPL), acting as biocapping agents and directing the growth of AuNPs over a period of time. The quantitative estimation of interparticle interactions and modification in Ostwald ripening (MOR) model were also done to correlate the growth kinetic of AuNPs. The X-ray photoelectron spectroscopy (XPS) showed the major contribution of oxygen, carbon and nitrogen elements, corresponding to polyphenolic, carboxylic and amides, in biocapping the surface of AuNPs and directing their interparticle interactions associated with growth kinetics. The Velec forces were reduced with an enhancement in the Vvdwforces, depicting their major role in impeding growth of AuNPs. The MOR model exhibited an excellent agreement of predicted growth with experimental size enlargements of AuNPs, having 4.8% average absolute relative percentage error.
