Development and Study of Nanoemulsions and Nanoemulsion-Based Hydrogels for the Encapsulation of Lipophilic Compounds

Biocompatible nanoemulsions and nanoemulsion-based hydrogels were formulated for the encapsulation and delivery of vitamin D-3 and curcumin. The aforementioned systems were structurally studied applying dynamic light scattering (DLS), electron paramagnetic resonance (EPR) spectroscopy and viscometry. In vitro studies were conducted using Franz diffusion cells to investigate the release of the bioactive compounds from the nanocarriers. The cytotoxicity of the nanoemulsions was investigated using the thiazolyl blue tetrazolium bromide (MTT) cell proliferation assay and RPMI 2650 nasal epithelial cells as in vitro model. DLS measurements showed that vitamin D-3 and curcumin addition in the dispersed phase of the nanoemulsions caused an increase in the size of the oil droplets from 78.6 +/- 0.2 nm to 83.6 +/- 0.3 nm and from 78.6 +/- 0.2 nm to 165.6 +/- 1.0 nm, respectively. Loaded nanoemulsions, in both cases, were stable for 60 days of storage at 25 degrees C. EPR spectroscopy revealed participation of vitamin D-3 and curcumin in the surfactants monolayer. In vitro release rates of both lipophilic compounds from the nanoemulsions were comparable to the corresponding ones from the nanoemulsion-based hydrogels. The developed o/w nanoemulsions did not exhibit cytotoxic effect up to the concentration threshold of 1 mg/mL in the cell culture medium.

High-temperature induced iodide and bromide ions filling lattice for high efficient all-inorganic perovskite solar cells

All inorganic CsPbX3 perovskites have gained great attentions owing to their excellent carrier transport property and thermal stability. However, the presence of X vacancy in the CsPbX3 lattice results in a high trap density within CsPbX3 films, and subsequently affects the photovoltaic performance of solar cells. Here, we use phenylethylammonium iodide (PEAL) and phenylethylammonium bromide (PEABr) to manipulate the film quality of inorganic perovskites, which significantly improve the moisture-resistance of the CsPbI2 Br film and photovoltaic performance. It is found that there is no so-called two-dimensional PEA(2)PbI(4) and PEA(2)PbBr(4) materials formed after a high temperature annealing, but iodine or bromide vacancies can be filled by external anions. The improved film quality with a low trap density renders the enhancement of the perovskite phase stability and the device efficiency of the CsPbI2Br solar cells. This work shows that filling vacancies by external anions can promote perovskite photovoltaic performance and stability. (C) 2020 Published by Elsevier B.V.

Preparation and characterization of positively surface charged zinc oxide nanoparticles against bacterial pathogens

Solvothermal synthesis was used to investigate the formation of zinc oxide (ZnO) nanoparticles (NPs). A series of ZnO NPs was synthesized with different relative ratios of didodecyldimethylammonium bromide (DDAB) and zinc nitrate (ZN). The variation in the molarity influenced the crystallinity, size, and morphology of the obtained ZnO NPs. X-ray diffraction, Fourier-transform infrared spectroscopy, field-emission scanning electron microscopy, high-resolution transmission electron microscopy, and zeta potential analysis were used to study the characteristic features of the ZnO NPs. The ZnO surface charge, size, and morphological structure were highly reliant on the concentrations of DDAB and ZN. With increasing relative ratio of DDAB to ZN, the particle size of ZnO NPs decreased and the surface charge increased to higher positive value. The ZnO NPs synthesized with cationic liquid DDAB presented enhanced performance in preventing the growth of Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) strains. The antibacterial activity of ZnO NPs have direct contact with the microbial cell wall resulting in destruction of bacterial cell integrity, release of antimicrobial Zn2+ ions, and induce cell death. This is due to the positively charged smaller ZnO NPs, prepared with DDAB cationic surfactant, effectively acting as an antimicrobial agent against food-borne pathogenic bacteria.

Knockdown of SALL4 inhibits the proliferation, migration, and invasion of human lung cancer cells in vivo and in vitro

Background: This study aimed to investigate the SALL4 expression in lung cancer, determine if SALL4 regulates the biological functions of lung cancer cells at the cellular level, and clarify the possible mechanisms involved. Methods: Immunohistochemistry was used to detect the SALL4 expression messenger RNA (mRNA) in 62 cases of lung cancer tissue microarray. The correlation of SALL4 with the clinical pathological parameters and overall life cycle of patients and the impact of disease-free life cycle was analyzed. Reverse transcriptionpolymerase chain reaction (RT-PCR) and western blotting were used to detect the SALL4 expression in lung cancer cell lines and nude mouse models. 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) assay, colony-forming assay, and flow cytometry were used to detect the effects of interference with SALL4 expression on lung cancer cell proliferation and transplant tumor models; the effect of interference with SALL4 expression on the growth of transplanted tumors in vivo was also examined. Results: SALL4 was highly expressed in lung cancer tissues and cell lines and was closely related to the patient’s TNM stage and lymph node metastasis. Compared to patients with a high SALL4 expression, those with a lower SALL4 expression had a longer overall and disease-free survival. The expression of SALL4 is an independent risk factor for the prognosis of lung cancer patients. Interference with SALL4 expression can significantly inhibit cell proliferation and clonal formation. Interfering with the expression of SALL4 can arrest the cells in the G0/G1 phase by inhibiting the expression of the cell cycle-related proteins, cyclin B, cyclin E, and cyclin D1. Furthermore, wound-healing and Transwell assays showed that interference with SALL4 expression could significantly inhibit the migration and invasion of lung cancer cells, while experiments in nude mice showed that interference with SALL4 expression could significantly inhibit the size and weight of transplanted tumors. Conclusions: SALL4 was highly expressed in lung cancer cell lines. Interference with the expression of SALL4 can effectively inhibit the proliferation, migration and invasion of lung cancer cells, promote cell cycle arrest, and play the function of tumor suppressor genes. SALL4 may be a new target for the diagnosis and treatment of lung cancer.

Ferrocenylated imine- and amine(secondary/tertiary)- phosphine P boolean AND N ligands and their Pd(II) complexes: Synthesis and structural characterization

A new family of ferrocenylated P<^>N ligands where the nitrogen donor is either of an imine or amine (secondary/tertiary), was synthesized. The condensation reaction between diphenylphosphino propylamine and formyl ferrocene led to the formation of imine ligand [(eta(5)-C5H5)Fe[(eta(5)-C5H4)CH=N-(CH2)(3)-PPh2)}] (1), which on reduction with NaBH4 gave secondary amine ligand [((eta(5)-C5H5)Fe[(eta(5)-C5H4)CH=N-(CH2)(3)-PPh2)}] (2). Additionally, nucleophilic substitution reaction of diphenylphosphino ethyl/propyl amine with [FcCH(2)NMe(3)(+)][I-] salt leads to tertiary-amine ligand [(eta(5)-C5H5)Fe[(eta(5)-C5H4)CH2](2)-N-(R-PPh2) where R = C2H4 (3) and C3H6 (4). The newly synthesized ferrocenylated ligands were then complexed with Pd(II) giving [cis(kappa(2)-P<^>N)PdCl2] type complexes (5-8), where imine, secondary amine, and tertiary amine ligands act as a bidentate ligand. The molecular structures of ligand (3), and complexes (5), (6), and (7) have also been determined by X-ray crystallography. In the molecular structures of these complexes, the Pd(II) center presents a distorted square-planar geometry. During the isolation of ligand (4), corresponding phosphine oxide (4A) along with a phosphonium salt (4B) was also isolated as by-products and were characterized by X-ray crystallography. The preliminary catalytic evaluation of complex (7) in the Suzuki-Miyaura cross-coupling reaction of arylboronic acids with aryl bromides was performed. (C) 2020 Elsevier B.V. All rights reserved.

Coating Mechanism of AuNPs onto Sepiolite by Experimental Research and MD Simulation

The amenability of gold nanoparticles (AuNPs) coating on natural and modified (hexadecyl trimethyl ammonium bromide, CTAB) sepiolite surfaces was studied both experimentally and theoretically. The zeta potential experiments and Fourier transform infrared spectrophotometer (FTIR), environmental scanning electron microscope (ESEM), and transmission electron microscopy (TEM) analyses were carried out with the sepiolite samples in the presence of AuNPs. In addition, the adsorption of three gold-nanoparticles on the sepiolite surface (100) in the absence and presence of CTAB was investigated by molecular dynamics (MD) simulations. The AuNPs showed no significant change in the zeta potential of natural sepiolite surfaces due to negative charges of both the sepiolite and AuNPs at natural pH. The surface charge of modified sepiolite decreased with the increase in AuNPs concentration indicating the significance AuNPs adsorption. FTIR, ESEM, and TEM analyses indicated the coating of AuNPs onto the modified sepiolite surface were higher than that of the natural sepiolite surface. The MD simulation results showed that AuNPs can easily adsorb onto the basal surface of the sepiolite due to its hydrophilicity in the presence and absence of CTAB as indicated in the experimental studies. In short, the modification of sepiolite with CTAB made the charge positive, and in turn considerably increased the AuNPs coating on sepiolite surfaces due to electrostatic attraction.

Solvent Quality-Mediated Regioselective Modification of Gold Nanorods with Thiol-Terminated Polymers

Modification of nanorods (NRs) with functional polymer ligands is of great significance to enhance their surface chemistry and prompt their applications in many fields (e.g., photothermal therapy, bioimaging, and catalysis). However, the regioselective modification of AuNRs still remains a great challenge. Herein, we introduce a facile yet versatile strategy to achieve the regioselective modification of AuNRs through a solvent quality-mediated strategy. By employing a poor solvent of the original ligand cetyltrimethylammonium bromide (CTAB) as the medium in the modification, polymer ligands would selectively graft onto the two ends of AuNRs, while polymer ligands would graft onto the entire surface when employing a good solvent. This strategy demonstrates good reproducibility and is applicable to both hydrophilic and hydrophobic polymer ligand modifications. Moreover, by combing our strategy with the preoccupation route, the two ends and sidewall of AuNRs modified by two different polymers form an ABA-type building block, which can further self-assemble into well-ordered superstructures. Our finding provides a new opportunity for multifunctionalization of NRs.

Rotation-restricted strategy to synthesize high molecular weight polyethylene using iminopyridyl nickel and palladium catalyst

Most of the iminopyridyl Ni (II) and Pd (II) catalysts are reported to oligomerize ethylene or yield very low molecular weight polyethylene. Moreover, the molecular weight of product is not sensitive to ligand sterics. In this contribution, we demonstrate that the bulky rotation-restricted substituents incorporated into iminopyridyl Ni (II) and Pd (II) catalysts that provide the right orientation are highly effective in retarding the chain transfer. Thus, (2,6-bis(10,11-dihydro-5H-dibenzo[a,d][7]annulen-5-yl)-4-methylphenyl)-1-(pyridin-2-yl)methanimine nickel (II) bromide (Ni3) and (2,6-bis(10,11-dihydro-5H-dibenzo[a,d][7]annulen-5-yl)-4-methylphenyl)-1-(pyridin-2-yl)methanimine palladium (II) methyl chloride (Pd3) with the phenyl substituents fixed in the diarylmethyl moiety produce polyethylene or functionalized polyethylene (ethylene-MA copolymer) with high M-n values up to 2.5 x 10(4) g mol(-1), while allowing the high MA incorporation (3.2%-13.8%). In addition, the effects on the (co)polymerization behavior as a function of rotation-restricted substituent variations (free rotation, restricted rotation and fixation) were systemically studied. As a result, various molecular weight polyethylene and ethylene-MA copolymer with high MA incorporation ratio were also obtained in this system.

Curcumin Promoted miR-34a Expression and Suppressed Proliferation of Gastric Cancer Cells

Background: To investigate the effects of curcumin on miR-34a and proliferation of gastric cancer cells. Materials and Methods: Human gastric cancer cell line SGC-7901 was divided into control, curcumin, miR-34a agomir (miR-34a), miR-34a agomir negative control, and curcumin combined miR-34a antagomir (combine) groups. 3-(4, 5-dimethylthiazolyl-2)-2, 5-diphenyltetrazolium bromide assay, scratch damage test, and transwell assay were used to detect cell proliferation, migration, and invasion. The cell apoptosis and cell cycle were detected by flow cytometry. Western blot was used to detect the expression of B-cell lymphoma-2 (Bcl-2), cyclin-dependent kinase 4 (CDK4), and cyclin D1. Terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling was used to detect apoptosis of tumors and Western blot was used to detect the expression of Bcl-2, CDK4, and cyclin D1 in tumors. Results: The results showed that curcumin markedly increased the content of miR-34a microRNA (mRNA) in SGC-7901 cells, inhibited proliferation, migration, and invasion of SGC-7901 cells, when compared to control group (p < 0.05). Compared with control group, curcumin significantly inhibited cell cycle progression in G0/G1-S phase, increased the cell number of G0/G1 phase, and downregulated the Bcl-2, CDK4, and cyclin D1 protein expression in cells and tissues (p < 0.05). After transfection of miR-34a agomir or antagomir into cells it was found that miR-34a agomir and curcumin had similar effects on resisting malignant biological behavior. Curcumin combined with miR-34a antagomir could weaken or reverse the above results. Conclusions: Curcumin could inhibit the proliferation and induce apoptosis of SGC-7901 cells. Its mechanism might be related to the miR-34a expression in cells, thus affecting the expression of Bcl-2, CDK4, and cyclin D1. Interested yet?

Performance analysis of a dual component generator-condenser of an absorption heat transformer for water desalination

The purpose of this work is to evaluate the behavior of a novel dual component: generator-condenser (GE-CO) applied to a single-stage absorption heat transformer for water desalination (SAHT-WD) by simple evaporation that operates with a LiBr-H2O mixture. The GE-CO consists of two sections located in the same shell, where desorption and condensation occur simultaneously. The evaluation has been divided into an experimental and a theoretical analysis. The experimental analysis is focused on determining the operating conditions that favor the performance of the GE-CO and the overall SAHT-WD. To estimate the heat transfer coefficients and wetting efficiencies based on the experimental results, a mathematical model that considers variation of the inlet absorption mixture stream, the refrigerant, the heating and cooling water was constructed. The results indicate a good coupling between the GE-CO and the AHT, with maximum values of COP and desalinated water flow of 0.49 and 3.91 x 10(-4) kg/s. The maximum specific desalination rate (SDR) of the AHT-WP was 1.10 x 10(-4) kg/s/kW. Both in the GE and CO, the heat transfers of the film of the absorbent mixture and the refrigerant respectively, limit the heat transfer process.
