Anticancer and apoptotic activity of biologically synthesized zinc oxide nanoparticles against human colon cancer HCT-116 cell line- in vitro study

Aim of this study was to synthesize the safe and stable zinc oxide nanoparticles (ZnONPs) from the leaves of Artocarpus heterophyllus. The alter in the color of the leaf extract dark brown upon addition of zinc nitrate Zn(NO3) confirms the formation of Zinc Oxide nanoparticles (ZnONPs). UV-VIS spectrophotometric analysis showed lambda max at 235 nm while Fourier transform infra-red (FTIR) spectroscopy showed various amines and amides are involved in the stabilization of ZnONPs. Energy dispersive X -rays (EDX) confirms the presence of zinc. Transmission electron microscopy (TEM) analysis revealed particle size ranges from 12 to 24 nm. These observed characteristic of nanoparticles are extremely useful in anticancer activities against HCT-116 colon cancer cell line. These ZnONPs showed IC50 value at 20 mu g/ml while on normal Vero cell line showed less effective by MTT assay. Furthermore, these nanoparticles were evaluated for apoptotic activity by acridine orange/ethidium bromide (AO/EB) double staining method showed the membrane blebbing and chromatin condensation.

Biofilm-Forming Ability of Pathogenic Bacteria Isolated from Retail Food in Poland

Biofilms have a significant impact on food safety in the food industry. Many foodborne outbreaks have been associated with pathogenic bacterial strains that can form a biofilm. The present study was conducted under the Official Control and Monitoring Program in Poland to examine the ability of pathogenic bacteria collected from retail food samples to form biofilms. Biofilm formation was assessed by qualitative detection of extracellular polymeric substances on Congo red agar, by adherence to glass with the tube method, by the crystal violet biofilm (CV) assay, and by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay. A total of 40 isolates from food samples (10 strains each of Listeria monocytogenes, Staphylococcus aureus, Escherichia coli, and Bacillus cereus) were examined. The strains were classified as adherent, slightly adherent, or nonadherent; biofilm production was classified as weak (WBP), moderate (MBP), or strong (SBP); and metabolic activity was classified as weak (WMA), moderate (MMA), or high (HMA). The incubation conditions and time influenced the amount of biofilm formed as well as did the growth medium. In the test tubes with Luria-Bertani broth (LBB), 22.5% of the strains were adherent and 77.5% were slightly adherent. Stronger adhesion was obtained in brain heart infusion (BHI) with 2% sucrose; 60% of the isolates were classified as adherent. With the CV assay with LBB, SBP was noted for 7.5% of the strains after 24 h of incubation and for 37.5% of the strains after 48 h. In BHI plus 2% sucrose, SBP was noted for 42.5 and 37.6% of the strains after 24 and 48 h, respectively. With the MTT assay with LBB, HMA was found for 15% of the strains after 24 h of incubation and for 25% of the strains after 48 h. In BHI plus 2% sucrose, 70 and 85% of the incubated strains were classified as HMA after 24 and 48 h, respectively.

Mitochondria-targeted cationic liposomes modified with alkyltriphenylphosphonium bromides loaded with hydrophilic drugs: preparation, cytotoxicity and colocalization assay

The purpose of this work was to obtain cationic liposomes based on 1,2-dipalmitoyl-sn-glycero-3-phosphocholine noncovalently modified using alkyltriphenylphosphonium bromides (TPPB-n) with different lengths of hydrocarbon tail for targeted delivery to mitochondria. The hydrodynamic diameter and electrokinetic potential of hybrid liposomes depending on the lipid/surfactant ratio were monitored in time with the aim to optimize the composition with sufficient stability and positive charge for mitochondria-targeted delivery. It was found that increasing the alkyl tail length of the surfactant (up to TPPB-14) leads to an increase in the positive charge of the liposomes. The most optimal results of stability were obtained for hybrid liposomes based on 1,2-dipalmitoyl-sn-glycero-3-phosphocholine and TPPB-12, TPPB-14. The obtained modified liposomes were loaded with hydrophilic substrates (a model probe Rhodamine B and medicines metronidazole and doxorubicin). This is one of the first examples of fabrication of liposomes noncovalently modified using an amphiphilic TPP cation, with the alkyl tail length of surfactant and TPP/lipid ratio optimized in terms of stability of the liposomes and the binding/release behavior of hydrophilic probes. Using the confocal microscopy method, it was shown that modification of liposomes with a triphenylphosphonium cation results in targeted delivery of encapsulated compounds to mitochondria.

Simultaneous Determination of Taurine, N-Acetylcysteine, Glycine and Methionine in Commercial Formulations by High-Performance Liquid Chromatography

A simple, inexpensive, reliable, selective and sensitive liquid chromatographic method was developed and validated for the simultaneous quantification of taurine (Tau), N-acetylcysteine (NAC), glycine (Gly) and methionine (Met) and applied for the first time to the analysis of commercial alimentary supplements. The amino acids (AAs) were analyzed after labeling reaction with 2,4-dinitrofluorobenzene (DNFB) in the presence of cetyltrimethylammonium bromide (CTAB). The derivatization reaction conditions were optimized and the derivatives were separated on a Phenomenex Synergi MAX-RP 4 mu m stainless steel column under gradient elution conditions. A mixture of triethylammonium (TEA) phosphate buffer (pH 3) and acetonitrile under gradient elution conditions was used as mobile phase at a flow rate of 0.4 mL/min, UV absorbance detection was set at lambda = 360 nm. Linear responses were obtained (determination coefficient >= 0.9996). Intra-day precision (RSD) was <= 1.71% for corrected peak area ratio (AA to internal standard) and <= 0.55% for retention times (t(R)) without significant differences between intra- and inter-day data. Recovery studies showed good results for all the examined compounds (from 99.26 to 99.90%; RSD <= 1.29%) %) with RSD <= 1.29%. The method was found to be specific and sensitive. The method can be useful for the quality control of commercial products. If you are interested in 768-90-1, you can contact me at any time and look forward to more communication.

Synergic Effect of Novel WS2 Carriers Holding Spherical Cobalt Ferrite @cubic Fe3O4 (WS2/s-CoFe2O4@c-Fe3O4) Nanocomposites in Magnetic Resonance Imaging and Photothermal Therapy for Ocular Treatments and Investigation of Corneal Endothelial Cell Migration

The design of novel materials to use simultaneously in an ocular system for driven therapeutics and wound healing is still challenging. Here, we produced nanocomposites of tungsten disulfide carriers with spherical cobalt ferrite nanoparticles (NPs) as core inside a cubic iron oxide NPs shell (WS2/s-CoFe2O4@c-Fe3O4). Transmission electron microscopy (TEM) confirmed that 10 nm s-CoFe2O4@c-Fe3O4 NPs were attached on the WS2 sheet surfaces. The cytotoxicity of the WS2 sheets and nanocomposites were evaluated on bovine cornea endothelial cells (BCECs) using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay for a duration of three days. The MTT assay results showed low toxicity of the WS2 sheets on BCECs by 67% cell viability at 100 mu g/mL in 24 h, while the nanocomposites show 50% cell viability in the same conditions. The magnetic resonance imaging (MRI) of nanocomposites revealed the excellent T-2-weighted imaging with an r(2) contrast of 108 mM(-1) S-1. The in vitro photothermal therapy based on WS2 sheets and WS2/s-CoFe2O4 @c-Fe3O4 nanocomposites using 808 nm laser showed that the maximum thermal energy dispatched in medium at different applied power densities (1200 mw, 1800, 2200, 2600 mW) was for 0.1 mg/mL of the sample solution. The migration assay of BCECs showed that the wound healing was approximately 20% slower for the cell exposed by nanocomposites compared with the control (no exposed BCECs). We believe that WS2/s-CoFe2O4@c-Fe3O4 nanocomposites have a synergic effect as photothermal therapy agents for eye diseases and could be a target in an ocular system using MRI.

Improving the Identification and Coverage of Plant Transmembrane Proteins in Medicago Using Bottom-Up Proteomics

Plant transmembrane proteins (TMPs) are essential for normal cellular homeostasis, nutrient exchange, and responses to environmental cues. Commonly used bottom-up proteomic approaches fail to identify a broad coverage of peptide fragments derived from TMPs. Here, we used mass spectrometry (MS) to compare the effectiveness of two solubilization and protein cleavage methods to identify shoot-derived TMPs from the legume Medicago. We compared a urea solubilization, trypsin Lys-C (UR-TLC) cleavage method to a formic acid solubilization, cyanogen bromide and trypsin Lys-C (FA-CTLC) cleavage method. We assessed the effectiveness of these methods by (i) comparing total protein identifications, (ii) determining how many TMPs were identified, and (iii) defining how many peptides incorporate all, or part, of transmembrane domains (TMD) sequences. The results show that the FA-CTLC method identified nine-fold more TMDs, and enriched more hydrophobic TMPs than the UR-TLC method. FA-CTLC identified more TMPs, particularly transporters, whereas UR-TLC preferentially identified TMPs with one TMD, particularly signaling proteins. The results suggest that combining plant membrane purification techniques with both the FA-CTLC and UR-TLC methods will achieve a more complete identification and coverage of TMPs.

Cobalt(II)-catalyzed preparation of alkylindium reagents and applications in cross-coupling with aryl halides

The direct insertion of indium powder into alkyl iodides was found to be efficiently catalyzed by a catalytic amount of cobalt(II) bromide (10 mol%). Upon subjection of the thus-formed alkylindium compounds to palladium-catalyzed cross-coupling reactions with a wide range of aryl halides, a series of cross-coupled products could be obtained in moderate to good yields with the tolerance to many important functional groups.

Highly active and stable Ni-incorporated spherical silica catalysts for CO(2)methanation

Nickel-doped spherical silica (SSP) catalysts with ca. 10 wt% Ni were prepared via a sol-gel method using cetyltrimethyl ammonium bromide as the structure directing agent with different loading sequences of Ni and Si sources (Si1_Ni2, Ni1_Si2, and Ni_Alt_Si). For comparison purposes, the SSP supported Ni catalysts were also prepared by impregnation method (Ni/SSP (Imp)). All the prepared catalysts showed spherical shape with high specific surface area (357-868m(2)/g). The X-ray diffraction and H-2-temperature programmed reduction results revealed the stronger interaction between Ni and SiO2 in the form of nickel silicate for all the Ni-doped SSP catalysts except Ni/SSP (imp), in which only NiO species were detected. For the reaction temperature 350 degrees C, the CO2 conversion was in the order: Ni_Alt_Si (51%) > Ni1_Si2 (49%) > Si1_Ni2 (28%) > Ni/SSP (Imp) (10%) with methane selectivity 80-95%. The superior performances of the Ni_Alt_Si catalyst were correlated well to the higher electron density of Ni on the surface and higher CO2 adsorption ability as revealed by the X-ray photoelectron spectroscopy and CO2-temperature program desorption results.

LiBr-promoted photoredox neutral Minisci hydroxyalkylations of quinolines with aldehydes

Photoredox-neutral hydroxyalkylations of quinolines with aldehydes, induced by sustainable visible light under mild conditions, are described. Non-toxic and inexpensive LiBr is found to be the key for the success of the atom-economical Minisci method. Combined with a highly oxidative photocatalyst and visible light irradiation, the bromide additive mediates the H abstraction/acyl radical formation directly from aldehydes. The present mild photoredox neutral protocol provides an important alternative, especially for the challenging Minisci hydroalkylations, as well as a promising approach for atom-economical Minisci reactions with broader N-heterocycle spectra.

Novel poly (ionic liquid)-based anion exchange membranes for efficient and rapid acid recovery from industrial waste

Owing to the less energy consumption, positive impact on the environment, and prospect of providing clean water resources, anion exchange membranes (AEMs) are promising materials for acid recovery from various industrial wastewater/effluent. Based on the diffusion dialysis process, AEMs selectively allow rapid proton permeation while efficiently retaining metal ions. To enhance the efficiency of the acid recovery process, precise control of macromolecular architecture and chemical composition that enables high hydrophilicity, proton conductivity through the membrane, and ion exchange capacity is required. In this direction, we report on the one-step fabrication of novel poly (ionic liquids)-based AEMs by the free radical polymerization of 1-butyl-3-vinyl imidazolium bromide, acrylic acid, styrene, and acrylonitrile under sunlight. The effect of monomer composition in an AEM matrix on the structural, physicochemical, surface, thermal, and proton conductivity is investigated. The experimentally determined acid dialysis coefficient (U-H+) obtained with synthesized poly (ionic liquid) based membranes PILM-1 and PILM-2 were 7.3 +/- 2 and 9.2 +/- 2 mh(-1) at room temperature (25 degrees C), while separation factors (SF) were 88.9 +/- 3 and 50.1 +/- 2, respectively. Both the U-H+ (> 700 times) and SF (> 4 times) are significantly values higher compared to the commercial AEM DF-120 (0.009 mh(-1) and 18.8 for U-H+ and SF, respectively). Thus, this study demonstrates the potential of the prepared AEMs as an alternate to deliver cost-effective, scalable, and rapid acid recovery compared to the currently existing technology.
