Substitute salts influencing the formation of PAHs in sodium-reduced bacon relevant to Maillard reactions

The influence of six sodium-reducing treatments (F2: 0.6% KCl+1.8% NaCl; F3: 0.6% CaCl2+1.8% NaCl; F4: 0.36% KCit+0.24% KCl+1.8% NaCl; F5: 0.12% MgCl2+0.48% CaCl2+1.8% NaCl; F6: 0.36% KL+0.24% KCl+1.8% NaCl; F7: 0.36% CaL+0.24% KCl+1.8% NaCl) on the formation of polycyclic aromatic hydrocarbons (PAHs) in baked bacon was evaluated. Compared with the total amount of the four PAH(4) (10.08 mu g/kg) in the control F1 group without sodium reduction, including (benzo [a]anthracene (BaA), chrysene (CHR), benzo [b] fluoranthene (BbFA), and benzo [a]pyrene (BaP), the application of F3 (6.37 mu g/kg), F5 (6.25 mu g/kg), F6 (5.85 mu g/kg) and F7 (5.56 mu g/kg) reduced the content of the PAH4 (P < 0.05), while the treatment of F4 (16.60 mu g/kg) increased the concentration of the PAH(4) (P < 0.05). The correlation analysis showed that the occurrence of PAH4 was significantly correlated with the pH and b* value (P < 0.05). The determination of hydroxymethylfurfural (HMF) content suggested that the influence of substitute salts on the PAH4 was related to Maillard reactions. A pH adjustment rescued the impact of the substitute salts on the b* value, the HMF content and the formation of PAH4, revealing that pH variations played a vital role in substitute salts influencing the generation of PAH4. Sodium sulphite decreased the b* value, the amount of the HMF and the concentration of PAH4 (P < 0.05), which further verified that substitute salts influence the formation of PAHs in sodium-reduced bacon in a mechanism involving Maillard reactions.

Efficient pyran derivatives synthesis in DES medium and their antimicrobial evaluation as inhibitors of mycobacterium bovis (BCG)

An ecofriendly one-pot three-component reaction of 1,3-dicarbonyl compounds, aromatic aldehydes and malononitrile was carried out in deep eutectic solvent (DES) based on choline chloride, to synthesize highly functionalized pyran derivatives under moderate conditions. The main advantages of this approach are mild reaction conditions, high yields, relaxed workup without chromatographic purification steps or extraction and easily reusable of DES’s. Then, these compounds were evaluated for anti-mycobacterium activity against Mycobacterium bovis (Bacillus Calmette-Guerin). The preliminary results indicated that most of the tested compounds showed relatively good activity against the test organism. The compounds 4a, 4c, 4e, 4n demonstrated the high activities against Mycobacterium (0.044-0.084 mu M/mL) and 4k showed highest activity (0.033 mu M/mL). The commonalities of these compounds are having a chlorine atom on the ring which is located on position 4 of the 4H-pyran structures. [GRAPHICS] .

Enrichment of alliin in different in vitro grown tissues of Allium sativum through CdCl2 elicitation as revealed by high performance thin layer chromatography (HPTLC)

Plant cell tissue and organ culture techniques provide an efficient way for the biosynthesis of high-value secondary metabolites in which elicitation has been recognized to be a potent approach in enriching the bioactive compounds. In this study, an effort was made to assess the influence of Cadmium chloride (CdCl2) on alliin yield of different in vitro grown tissues such as callus, somatic embryos, leaves and roots of Allium sativum. The tissues were cultured in MS amended with various levels of CdCl2 [control (0 mM), T1 (0.05 mM), T2 (0.1 mM), T3 (0.15 mM) and T4 (0.2 mM)] and the yield of alliin was quantified by using high performance thin layer chromatography (HPTLC). Biochemical analyses revealed that sample tissues under increasing CdCl2 conditions accumulated higher levels of sugar, protein and proline with maximum content of sugar (19.61 mg g(-1) FW), protein (6.01 mg g(-1) FW) and proline (12.19 mg g(-1) FW) in leaves at T3 after 4 days of elicitor treatment. Changes within the activities of varied antioxidant enzymes like catalase (CAT), superoxide dismutase (SOD) and ascorbate peroxidase (APX) was assayed as the addition of CdCl2 in the medium causes stress. We noted that with an elevated level of CdCl2, antioxidant enzyme activity increased linearly with the highest activity observed in leaves at T4 of 6 days of elicitation (4.97 EU min(-1) mg(-1) protein CAT, 6.30 EU min(-1) mg(-1) protein SOD and 1.125 EU min(-1) mg(-1) protein APX). Increased activities of enzymes are involved in negating the cellular stress triggered due to the overproduction of ROS. The yield of alliin in response to varying levels of CdCl2 was estimated by using a simple, rapid, and sensitive HPTLC method. The best separation was achieved using butanol: propanol:acetic acid:water (3:1:1:1) as mobile phase. For analysis of alliin, the plates were scanned at 550 nm after spraying with ninhydrin and a good resolution was achieved with Rf value of 0.66. In our study, the alliin yield enhanced in all tested cultures with the elicitor level up to T3. In leaves, maximum accumulation of alliin (3.37 mu g g(-1) dry wt.) was noted on 0.15 mM (T3) CdCl2 added medium. Our data indicated the increase of alliin in CdCl2 added cultures, which suggests that the use of elicitors as a potential strategy for augmenting secondary metabolite synthesis.

Apoptosis-antagonizing transcription factor is involved in rat post-traumatic epilepsy pathogenesis

The present study aimed to explore the pathogenesis behind post-traumatic epilepsy (PTE). In the present study, a chloride ferric injection-induced rat PTE model was established. The expression levels of apoptosis-antagonizing transcription factor (AATF), cleaved caspase-3, p53, Bcl-2 and Bax were measured by western blotting or immunofluorescence staining (IF). The expression of AATF in vivo was downregulated by microinjection of lentiviral-mediated short-hairpin RNA. Compared with control and sham groups, at day 5 after PTE, neuron apoptosis was significantly increased and the expression levels of AATF, p53, cleaved caspase-3 and Bax were significantly upregulated. In addition, IF revealed co-localization of AATF and cleaved caspase-3 in the cortex. Additionally, AATF was expressed mainly in neurons and astrocytes. Following AATF inhibition, the expression levels of p53 and cleaved caspase-3 were significantly reduced as compared with the control group. Taken together, these findings suggested that following PTE, AATF is involved in neuronal apoptosis and may serve as a potential target for its alleviation.

Investigation of PolyVinyl Chloride Plastisol Tissue-Mimicking Phantoms for MR- and Ultrasound-Elastography

Objective: Realistic tissue-mimicking phantoms are essential for the development, the investigation and the calibration of medical imaging techniques and protocols. Because it requires taking both mechanical and imaging properties into account, the development of robust, calibrated phantoms is a major challenge in elastography. Soft polyvinyl chloride gels in a liquid plasticizer (plastisol or PVCP) have been proposed as soft tissue-mimicking phantoms (TMP) for elasticity imaging. PVCP phantoms are relatively low-cost and can be easily stored over long time periods without any specific requirements. In this work, the preparation of a PVCP gel phantom for both MR and ultrasound-elastography is proposed and its acoustic, NMR and mechanical properties are studied. Materials and methods: The acoustic and magnetic resonance imaging properties of PVCP are measured for different mass ratios between ultrasound speckle particles and PVCP solution, and between resin and plasticizer. The linear mechanical properties of plastisol samples are then investigated over time using not only indentation tests, but also MR and ultrasound-elastography clinical protocols. These properties are compared to typical values reported for biological soft tissues and to the values found in the literature for PVCP gels. Results and conclusions: After a period of two weeks, the mechanical properties of the plastisol samples measured with indentation testing are stable for at least the following 4 weeks (end of follow-up period 43 days after gelation-fusion). Neither the mechanical nor the NMR properties of plastisol gels were found to be affected by the addition of cellulose as acoustic speckle. Mechanical properties of the proposed gels were successfully characterized by clinical, commercially-available MR Elastography and sonoelastography protocols. PVCP with a mass ratio of ultrasound speckle particles of 0.6%-0.8% and a mass ratio between resin and plasticizer between 50 and 70% appears as a good TMP candidate that can be used with both MR and ultrasound-based elastography methods.

Catalytically active nanosized Pd9Te4 (telluropalladinite) and PdTe (kotulskite) alloys: first precursor-architecture controlled synthesis using palladium complexes of organotellurium compounds as single source precursors

Several intermetallic binary phases of Pd-Te including Pd3Te2, PdTe, PdTe2, Pd9Te4, Pd3Te, Pd2Te, Pd20Te7, Pd8Te3, Pd7Te2, Pd7Te3, Pd4Te and Pd17Te4 are known, and negligible work (except few studies on PdTe) has been done on exploring applications of such phases and their fabrication at nanoscale. Hence, Pd(ii) complexes Pd(L1)Cl-2 and Pd(L2-H)Cl (L1): Ph-Te-CH2-CH2-NH2 and L2: HO-2-C6H4-CH = N-CH2CH2-Te-Ph were synthesized. Under similar thermolytic conditions, complex Pd(L1)Cl-2 with bidentate coordination mode of ligand provided nanostructures of Pd9Te4 (telluropalladinite) whereas Pd(L2-H)Cl with tridentate coordination mode of ligand yielded PdTe (kotulskite). Bimetallic alloy nanostructures possess high catalytic potential for Suzuki coupling of aryl chlorides, and reduction of 4-nitrophenol. They are also recyclable upto six reaction cycles in Suzuki coupling.

Nanoencapsulation of food bioactives in supramolecular assemblies based on cyclodextrins and surfactant

The bioavailability of poorly soluble food ingredients can be achieved by their encapsulation into the 3D macrocyclic structure or self-assembled surfactant micelles. In this study, the mixed self-assembly of cyclodextrins (CDs) and cationic surfactant, 1-hexadecyl-4-(2-(1-methylpyridin-1-ium-4-yl)vinyl)pyridin-1-ium chloride, was studied by a set of physicochemical methods. It was shown using tensiometry and conductometry that the presence of CDs in the micellar medium of this surfactant increases the critical aggregation concentration. Moreover, NMR spectroscopy and spectrophotometry revealed the interaction between the alkyl tail of surfactant and the internal cavity of CDs. It is interesting to note that in the case of gamma-CD and HP-beta-CD there was additional binding by the vinyl group of surfactant. The observed patterns of aggregation behavior were confirmed by the method of solubilization of hydrophobic substances. Spectrophotometric monitoring of the solubilization of hydrophobic flavonoids (rutin and quercetin) demonstrated that mixed assemblies enriched with surfactant are capable of binding the flavonoid, while they show poor binding ability towards flavonol compound in the presence of a small amount of surfactant.. Variation of the component ratio in the supramolecular CD-surfactant system also allows adjusting the biological properties. Systems with an excess of CD are less toxic to the cells of test microorganisms, herewith, an increase of the surfactant content in a mixture with CD leads to an increase in both antimicrobial and hemolytic activities. Therefore, when using CD complex-based supramolecular approach for food safety, it is necessary to take into account the toxic properties of the base components of the supramolecular mixture.

Chemically Durable Poly(phenylene-co-arylene ether) Multiblock Copolymer-Based Anion Exchange Membranes with Different Hydrophobic Moieties for Application in Fuel Cells

Quaternized multiblock poly(phenylene-co-arylene ether)s (QPPs) are synthesized from a pre-aminated monomer and a series of chlorine-terminated oligo(arylene-ethers) via a nickel coupling reaction. Their properties are investigated as anion exchange membranes with the goal of obtaining membranes with enhanced performance and durability for alkaline membrane fuel cell applications. Three different oligo(arylene ethers) were synthesized and introduced in the hydrophobic block of the polymer backbone to study its effect on the membrane properties. The chloride ion conductivity of the QPP membranes was significantly less dependent on the humidity compared to that of the commercial Fumatech membrane due to the well-defined hydrophilic-hydrophobic phase separation, as confirmed by TEM. An accelerated alkaline stability test indicated that the QPPs were more stable than the commercial Fumatech membrane up to 1700 h. The QPP-6F membrane shows an alkaline membrane fuel cell single-cell performance with a maximum power density of 534 mW cm(-2) at 70 degrees C.

On the ligand exchange, redox, and disproportionation processes of tetrachloroaurate in the presence of a pyridine derivative

The potential applications of Au-I precursors and pyridine derivatives for shape-directed nanoparticle growth has provided an impetus for the present study of the chemistry of tetrachloroaurate (AuCl4-) in the presence of 4-methoxypyridine (Py-/). Electrochemical experiments show that the addition of Py-/ to AuCl4-leads to the co-existence of both Au-III and Au-I species as evidenced by the observation of two reduction events in the cyclic voltammetry. Kinetic analyses have been used to show that multiple ligand exchange processes occur over the course of several minutes and result in the formation of a Au-III species with two Py-/ and a variable number of chloro and hydroxo ligands in the inner sphere. The kinetics of the initial Py-/ substitution reaction are shown to follow a modified form of the two-term rate law typical of square planar complexes. The observation of a slow, but spontaneous, conversion of Au-III species to Au-I species has been explained by estimating the standard reduction potential for the pyridine/pyridine-N-oxide redox couple and demonstrating that it can drive a galvanic reaction with the AuPy/Cl-2(q)(OH)(2-q)(+)/AuPy2/+ redox couple. The previously reported tendency of this system to form highly anisotropic gold nanoparticles on conductive metal oxide electrodes is explained by a thermodynamic analysis of the disproportionation reaction of AuPy2/+ (C) 2020 Elsevier Ltd.
