The usefulness of higher-order structural information provided by hydrogen/deuterium exchange-mass spectrometry (H/DX-MS) for the structural impact analyses of chemical and post-translational antibody modifications has been demonstrated in various studies. However, the structure-function assessment for protein drugs in biopharmaceutical research and development is often impeded by the relatively low-abundance (below 5%) of critical quality attributes or by overlapping effects of modifications, such as glycosylation, with chemical amino acid modifications; e.g., oxidation or deamidation. We present results demonstrating the applicability of the H/DX-MS technique to monitor conformational changes of specific Fc glycosylation variants produced by in vitro glyco-engineering technology. A trend towards less H/DX in Fc C gamma 2 domain segments correlating with larger glycan structures could be confirmed. Furthermore, significant deuterium uptake differences and corresponding binding properties to Fc receptors (as monitored by SPR) between alpha-2,3- and alpha-2,6-sialylated Fc glycosylation variants were verified at sensitive levels.

Emerging data indicate that endocannabinoid signaling is critical to the formation of habitual behavior. Previous work demonstrated that antagonism of cannabinoid receptor type 1 (CB1R) with AM251 during operant training impairs habit formation, but it is not known if this behavioral effect is specific to disrupted signaling of the endocannabinoid ligands anandamide or 2-arachidonoyl glycerol (2-AG). Here, we used selective pharmacological compounds during operant training to determine the impact of fatty acid amide hydrolase (FAAH) inhibition to increase anandamide (and other n-acylethanolamines) or monoacylglycerol lipase (MAGL) inhibition to increase 2-AG levels on the formation of habitual behaviors in mice using a food-reinforced contingency degradation procedure. We found, contrary to our hypothesis, that inhibition of FAAH and of MAGL disrupted the formation of habits. Next, AM251 was administered during training to verify that impaired habit formation could be assessed using contingency degradation. AM251-exposed mice responded at lower rates during training and at higher rates in the test. To understand the inconsistency with published data, we performed a proof-of-principle dose-response experiment to compare AM251 in our vehicle-solution to the published vehicle-suspension on response rates. We found consistent reductions in response rate with increasing doses of AM251 in solution and an inconsistent dose-response relationship with AM251 in suspension. Together, our data suggest that further characterization of the role of CB1R signaling in the formation of habitual responding is warranted and that augmenting endocannabinoids may have clinical utility for prophylactically preventing aberrant habit formation such as that hypothesized to occur in substance use disorders.

Analogues of dibenzodiazepines, inwhich the seven-membered nitrogen heterocycle is replaced by a 9-12-membered ring, were made by an unactivated Smiles rearrangement of five-to eight-membered heterocyclic anthranilamides. The conformational preference of the tertiary amide in the starting material leads to intramolecular migration of a range of aryl rings, even those lacking electron-withdrawing activating groups, and provides a method for n -> n + 4 ring expansion. The medium-ring products adopt a chiral ground state with an intramolecular, transannular hydrogen bond. The rate of interconversion of their enantiomeric conformers depends on solvent polarity. Ring size and adjacent steric hindrance modulate this hidden hydrophilicity, thus making this scaffold a good candidate for drug development.

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 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.
