(2-Carboxyethyl) dimethylsulfonium bromide supplementation in non-fish meal diets for on-growing grass carp (Ctenopharyngodon idella): Beneficial effects on immune function of the immune organs via modulation of NF-kappa B and TOR signalling pathway

The immune function of immune organs is extremely crucial for maintaining organism health status, which ultimately affects fish growth. Our previous study has found that dietary supplementation of (2-carboxyethyl) dimethylsulfonium Bromide (Br-DMPT) in non-fish meal (NFM) diet could promote the growth of grass carp (Ctenopharyngodon idella), whereas the underlying reason or mechanism for this results is largely unclear. Herein, we further explored whether dietary supplementation of Br-DMPT promoted fish growth is connected with the enhanced immune function in the immune organs (the head kidney, spleen and skin). In this study, 540 fish (216.49 +/- 0.29 g) were irregularly distributed to six groups with three replicates (30 fish replicate 1) and fed corresponding diets group containing a fish meal (FM) diet group and five different NFM diets supplemented with gradational Br-DMPT (0-520.0 mg/kg level) group for 60 days. After the 60-days feeding trial, 8 fish from each replicate were selected and then conducted a challenge test with A. hydrophila for 14 days. Our results indicated that in the NFM diets, appropriate Br-DMPT: (1) significantly decreased the morbidity of skin haemorrhage and lesion after A. hydrophila infection (P < 0.05). (2) significantly improved the innate and adaptive immune components (lysozyme, complement 3, immunoglobulin M and antibacterial peptides et al.) (P < 0.05). (3) increased the gene expressions of main anti-inflammatory cytokines partially by referring to TOR signalling pathway, and decreased the gene expressions of main pro-inflammatory cytokines partially by referring to NF-kB signalling pathway (P < 0.05). Strikingly, no statistical difference could be found in the most of above immune parameters between 260.0 mg/kg Br-DMPT diet group and FM diet group (P > 0.05). Taken together, in non-fish meal diet, appropriate supplementation of Br-DMPT could improve the disease resistance capacity, non-specific immunity and ameliorate inflammation, and simultaneously could mitigate these adverse effects induced by the non-fish meal diet in fish immune organs. Moreover, this study may be helpful to decipher the underlying mechanisms of how Br-DMPT promote fish growth by immune organs and also provide scientific theoretical evidence for the future application of Br-DMPT as a new immunopotentiator in aquaculture industry.

Highly thermally stable mesoporous Poly(cyanate ester) featuring double-decker-shaped polyhedral silsesquioxane framework

In this study we prepared cyanate ester-functionalized double-decker silsesquioxane (DDSQ) nanoparticles through a sequence of hydrosilylation of nadic anhydride (ND) with DDSQ and then treat with 4-aminophenol to provide DDSQ-ND-OH, and reaction with cyanogen bromide (BrCN) to form DDSQ-ND-OCN (a bis-phenyl cyanate ester DDSQ). After thermal curing of DDSQ-ND-OCN, we obtained mesoporous poly(cyanate ester) (PCE)/DDSQ frameworks that displayed high thermal stabilities and char yields since the inorganic DDSQ nanoparticles were dispersed in the PCE matrix homogeneously, as revealed using electron microscopy. Thermal polymerization at 210 degrees C provided a PCE/DDSQ framework having a thermal decomposition temperature (516 degrees C) and char yield (70 wt%); these values increased to 600 degrees C and 81 wt%, respectively, after thermal treatment at 420 degrees C. More interestingly, these mesoporous PCE/DDSQ frameworks displayed electrochemical properties better than those of other non-carbonized materials.

Influence of the alkali cation size on the Cu2+ coordination environments in (AX)[Cu(HSeO3)(2)] (A = Na, K, NH4, Rb, Cs; X = Cl, Br) layered copper hydrogen selenite halides

Using solution evaporation techniques, we succeeded in preparation of new members essentially extending the layered copper hydrogen selenite family, (AX)[Cu(HSeO3)(2)] with A=Na, K, Rb, Cs, and NH4, and X= Cl and Br. Bromides and chlorides are isostructural in the family of described new compounds crystallizing in three different structure types. (NaX)[Cu(HSeO3)(2)] and (KX)[Cu(HSeO3)(2)] (X = CI, Br) are monoclinic, whereas (AX) [Cu(HSeO3)(2)] (A = NH4, Rb, Cs; X = Cl, Br) are orthorhombic. Upon the enlargement of the A’ ionic radii inserted in the interlayer between the neighboring [Cu(HSeO3)(2)] slabs, the effective distance is increasing and results in essential elongation of the apical Cu-X (X = Cl, Br) distances. Three different types of CuO4Xn (n=0-2) polyhedra are formed. The observed trend is an interesting example of the chemical tuning of the Cu2+ coordination environments.

Energy Transfer from Perovskite Nanocrystals to Dye Molecules Does Not Occur by FRET

Single formamidinium lead bromide (FAPbBr(3)) perovskite nanocubes, approximately 10 nm in size, have extinction cross sections orders of magnitude larger than single dye molecules and can therefore be used to photoexcite one single dye molecule within their immediate vicinity by means of excitation-energy transfer (EET). The rate of photon emission by the single dye molecule is increased by 2 orders of magnitude under excitation by EET compared to direct excitation at the same laser fluence. Because the dye cannot accommodate biexcitons, NC biexcitons are filtered out by EET, giving rise to up to an order-of-magnitude improvement in the fidelity of photon antibunching. We demonstrate here that, contrary to expectation, energy transfer from the nanocrystal to dye molecules does not depend on the spectral line widths of the donor and acceptor and is therefore not governed by Forster’s theory of resonance energy transfer (FRET). Two different cyanine dye acceptors with substantially different spectral overlaps with the nanocrystal donor show a similar light-harvesting capability. Cooling the sample from room temperature to 5 K reduces the average transition line widths 25-fold but has no apparent effect on the number of molecules emitting, i.e., on the spatial density of single dye molecules being photoexcited by single nanocrystals. Narrow zero-phonon lines are identified for both donor and acceptor, with an energetic separation of over 40 times the line width, implying a complete absence of spectral overlap-even though EET is evident. Both donor and acceptor exhibit spectral fluctuations, but no correlation is apparent between the jitter, which controls spectral overlap, and the overall light harvesting. We conclude that the energy transfer process is fundamentally nonresonant, implying effective energy dissipation in the perovskite donor because of strong electron-phonon coupling of the carriers comprising the exciton. The work highlights the importance of performing cryogenic spectroscopy to reveal the underlying mechanisms of energy transfer in complex donor-acceptor systems.

Polymorphism of TPH2 Gene rs120074175 Is Not Associated with Risk Factors of Schizophrenia

Context: Polymorphism on tryptophan hydroxylase 2 (TPH2) gene rs120074175 can cause the synthesis of neurotransmitter serotonin in the brain to reduce up to 80%. Reduced serotonin in the brain can cause dopamine release to occur continuously. Excess dopamine in the brain may cause positive symptom of schizophrenia. Aim: The aim of this study was to investigate the genotype distribution of TPH2 rs120074175 gene on patients with schizophrenia at Prof. Dr. Soerojo Magelang Psychiatric Hospital, Indonesia, and the relationship between the genetic polymorphism of the TPH2 rs120074175 gene against risk factors of schizophrenia. Settings and Design: This was a cross-sectional study. Materials and Methods: The method used was amplification refractory mutation systempolymerase chain reaction (ARMS-PCR). Whole blood from healthy subjects and patients with schizophrenia, Wizard genomic deoxyribonucleic acid (DNA) purification kit (Promega, Fitchburg, Wisconsin), PCR master mix (Promega), ARMS-PCR primers, ddH(2)O, agarose (Thermo Scientific, Seoul, South Korea), Tris, Acetic Acid, EDTA (TAE) 1X, ethidium bromide, loading dye 6x, and DNA ladder (Thermo Scientific) were the materials used. Statistical Analysis: Hardy-Weinberg equilibrium and chi-square (similar to 2) tests were used. Results: The results showed that both groups (healthy subjects and patients with schizophrenia) at the Prof. Dr. Soerojo Magelang Psychiatric Hospital have a wild-type GG genotype (100%) without anyone having a mutant A allele. Conclusion: TPH2 rs120074175 gene polymorphism was not associated with risk factors for schizophrenia.

Study of the modification of bentonite for the formation of nanocomposite hydrogels with potential applicability in conformance control

In this work, the structure of bentonite clay was modified by ion exchange mechanism using 30%, 60% and 100% of its cation exchange capacity (CEC) with the surfactants hexadecyltrimethylammonium bromide, tetramethylammonium bromide, and trimethylphenylammonium bromide. The organically modified clay samples were characterized by Fourier-transform infrared spectrometry (FTIR), thermogravimetric analysis (TGA), X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX). The clays modified with hexadecyltrimethylammonium bromide presented the best results and were used for the formation of nanocomposite hydrogels and the systems were characterized by FTIR, TGA, SEM and rheological analysis. Thus, it was observed that the systems produced with 100% hexadecyltrimethylammonium bromide modified clay presented better properties and nanofiller showed better reinforcement capacity due to the greater interaction between the organophilic clay and the polymeric matrix.

Determination of lipoic acid in human plasma by high-performance liquid chromatography with ultraviolet detection

This paper describes the development and validation of an HPLC method for the determination of protein bound and total lipoic acid in human plasma. The essential steps in the total lipoic acid assay include reduction of disulfide bridge with tris(2-carboxyethyl)phosphine, derivatization via thiol group with 1-benzyl-2-chloropyridinium bromide and HPLC analysis of S-pyridinium derivative. Protein-bound lipoic acid is first separated from free lipoic acid with the use of liquid extraction, converted to its reduced counterpart then processed as total lipoic acid. The method is reproducible, precise and accurate. The inter- and intraday related standard deviation varied from 1.5% to 11.5% and from 1.8% to 19.6%, respectively, while recovery is in the range of 80.0-106.0% and 80.4-110.8%, respectively. The mean concentration of total lipoic acid in healthy donors after supplementation with 600 mg and 1200 mg was 0.67 +/- 0.40 mu mol L-1 (137.6 +/- 82.1 mu g L-1) and 1.57 +/- 0.34 mu mol L-1 (323.34 +/- 70.07 mu g L-1), respectively.

RETRACTED: LncRNA OIP5-AS1 contributes to ox-LDL-induced inflammation and oxidative stress through regulating the miR-128-3p/CDKN2A axis in macrophages (Retracted article. See vol. 11, pg. 5241, 2021)

Long non-coding RNA OIP5-AS1 (lncRNA OIP5-AS1) and microRNA-128-3p (miRNA-128-3p) have been reported to play significant roles in human diseases. However, their role in atherosclerosis (AS) has been less studied. The aim of this research was to reveal the roles and functional mechanisms of OIP5-AS1 and miRNA-128-3p in AS development. Quantitative real-time polymerase chain reaction (qRT-PCR) and western blot assays were performed to detect gene expression. Cell proliferation and apoptosis were assessed using a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and flow cytometry analysis, respectively. In addition, ELISA was employed to determine the levels of interleukin (IL)-6, IL-1 beta, and tumor necrosis factor (TNF)-alpha. Oxidative stress was examined using a relevant kit. Furthermore, the interaction between miR-128-3p and OIP5-AS1 or cyclin-dependent kinase inhibitor 2A (CDKN2A) was predicted using StarBase, and then confirmed using the dual-luciferase reporter assay or the RNA immunoprecipitation (RIP) assay. We found that OIP5-AS1 and CDKN2A levels were upregulated and the miR-128-3p level was downregulated in oxidized low-density lipoprotein (ox-LDL)-induced THP1 cells. OIP5-AS1 knockdown weakened the regulatory effect of ox-LDL on cell progression. Interestingly, OIP5-AS1 directly interacted with miR-128-3p and miR-128-3p-targeted CDKN2A. Furthermore, OIP5-AS1 regulated ox-LDL-induced cell progression through modulating miR-128-3p expression, and miR-128-3p exerted its influence by modulating the CDKN2A level. Finally, we confirmed that OIP5-AS1 suppressed miR-128-3p expression to increase the level of CDKN2A. In conclusion, our findings demonstrate that OIP5-AS1 knockdown repressed the effect of ox-LDL on cell progression through regulating the miR-128-3p/CDKN2A axis, providing a potential target for the treatment of AS.

Supramolecular Solvent-Based Liquid Phase Microextraction Combined with Ion-Pairing Reversed-Phase HPLC for the Determination of Quats in Vegetable Samples

In this study, we used anion supramolecular solvent (SUPRAS) prepared from a mixture of an anionic surfactant, sodium dodecyl sulfate (SDS), and a cationic surfactant, tetrabutylammonium bromide (TBABr), as the extraction solvent in liquid phase microextraction (LPME) of paraquat (PQ) and diquat (DQ). The enriched PQ and DQ in the SUPRAS phase were simultaneously analyzed by ion-pairing reversed-phase high performance liquid chromatography. PQ and DQ were successfully extracted by LPME via electrostatic interaction between the positive charge of the quats and the negative charge of SUPRAS. PQ, DQ, and ethyl viologen (the internal standard) were separated within 15 min on a C18 column, with the mobile phase containing 1-dodecanesulfonic acid and triethylamine, via UV detection. The optimized conditions for the extraction of 10 mL aqueous solution are 50 mu L of SUPRAS prepared from a mixture of SDS and TBABr at a mole ratio of 1:0.5, vortexed for 10 s at 1800 rpm, and centrifugation for 1 min at 3500 rpm. The obtained enrichment factors were 22 and 26 with limits of detection of 1.5 and 2.8 mu g L-1 for DQ and PQ, respectively. The precision was good with relative standard deviations less than 3.86%. The proposed method was successfully applied for the determination of PQ and DQ in vegetable samples and recoveries were found in the range of 75.0% to 106.7%.

Predicting Melting Points of Biofriendly Choline-Based Ionic Liquids with Molecular Dynamics

Featured Application The developed fully simulation-based melting point prediction method facilitates the design of novel green ionic liquids. Abstract In this work, we introduce a simulation-based method for predicting the melting point of ionic liquids without prior knowledge of their crystal structure. We run molecular dynamics simulations of biofriendly, choline cation-based ionic liquids and apply the method to predict their melting point. The root-mean-square error of the predicted values is below 24 K. We advocate that such precision is sufficient for designing ionic liquids with relatively low melting points. The workflow for simulations is available for everyone and can be adopted for any species from the wide chemical space of ionic liquids.
