A simple hypochlorous acid signaling probe based on resorufin carbonodithioate and its biological application

A novel hypochlorous-acid-selective signaling probe based on the carbonodithioate derivative of resorufin (RT-1) was developed. Probe RT-1 showed prominent colorimetric and turn-on type fluorescence signaling behavior exclusively toward hypochlorous acid, induced by oxidative hydrolysis, to regenerate resorufin dye. Hypochlorous acid signaling was not affected by the presence of common metal ions and anions as background, except for the redox active bromide and iodide anions. The detection limit of RT-1 for hypochlorous acid was found to be 2.18 x 10(-9) M (0.11 ppb), and the signaling was completed within 3 min. It was also confirmed that hypochlorous acid signaling by the carbonodithioate-based probe RT-1 was superior to that of the closely related carbonothioate derivative RT-2. This was rationalized by density functional theory calculations, which demonstrated that the CS sulfur atom of the former is more negatively charged than that of the latter. Finally, as a biological application of the probe, visualization of hypochlorous acid in RAW 264.7 murine macrophages and HeLa cells was successfully conducted to detect the cellular response to hypochlorous acid.

Effect of oxoanions on oxidant decay, bromate and brominated disinfection by-product formation during chlorination in the presence of copper corrosion products

The present study investigated the effect of oxoanions on catalytic behaviour of copper corrosion products (CCPs) during chlorination of bromide-containing waters. Three types of oxoanions (carbonate, sulphate, and phosphate) and four types of CCPs (Cu2+, Cu(OH)(2), Cu2O, and CuO) were involved in investigation and the effect of oxoanions concentration was also examined. The result indicated that carbonate and sulphate slightly inhibited oxidant decay in the presence of CCPs, but the formation of brominated disinfection by-products (Br-DBPs) remained largely unchanged. In contrast, the presence of phosphate (0.2-1 mM) almost eliminated the catalytic effect of Cu2+. For CCP solids (i.e. Cu(OH)2, Cu2O, and CuO), phosphate preferentially inhibited the formation of bromate rather than Br-DBPs. Despite the catalysis by CCP solids was reduced to some extent, the oxidant decay rate and bromate and Br-DBP formation were still significantly higher than blank groups, even at high phosphate concentration. By testing different addition scheme (simultaneous/sequential addition), it was proposed that phosphate was a strong competitor for hypohalites, rapidly destroying CCPs-hypohalites complexes on some adsorption sites. However, there were some specific sites that can only be adsorbed by hypohalites, leading to the incomplete inhibition of phosphate. Finally, the inhibition effect of phosphate on CCPs catalysis was tested in real water matrix. For Cu2+, higher reduction of bromate and Br-DBPs was found in raw water rather than filtered water, while converse pattern was true for Cu(OH)(2) and Cu2O, and this discrepancy can be ascribed to the difference in catalytic mechanism between Cu2+ and CCP solids.

Circ_0008039 supports breast cancer cell proliferation, migration, invasion, and glycolysis by regulating the miR-140-3p/SKA2 axis

Circular RNAs (circRNAs) have been shown to modulate gene expression and participate in the development of multiple malignancies. The purpose of this study was to investigate the role of circ_0008039 in breast cancer (BC). The expression of circ_0008039, miR-140-3p, and spindle and kinetochore-associated protein 2 (SKA2) was detected by qRT-PCR. Cell viability, colony formation, migration, and invasion were evaluated using methylthiazolyldiphenyl-tetrazolium bromide (MTT) assay, colony formation assay, and transwell assay, respectively. Glucose consumption and lactate production were measured using commercial kits. Protein levels of hexokinase II (HK2) and SKA2 were determined by western blot. The interaction between miR-140-3p and circ_0008039 or SKA2 was verified by dual-luciferase reporter assay. Finally, a mouse xenograft model was established to investigate the roles of circ_0008039 in BC in vivo. We found that circ_0008039 and SKA2 were upregulated in BC tissues and cells, while miR-140-3p was downregulated. Knockdown of circ_0008039 suppressed BC cell proliferation, migration, invasion, and glycolysis. Moreover, miR-140-3p could bind to circ_0008039 and its inhibition reversed the inhibitory effect of circ_0008039 interference on proliferation, migration, invasion, and glycolysis in BC cells. SKA2 was verified as a direct target of miR-140-3p and its overexpression partially inhibited the suppressive effect of miR-140-3p restoration in BC cells. Additionally, circ_0008039 positively regulated SKA2 expression by sponging miR-140-3p. Consistently, silencing circ_0008039 restrained tumor growth via increasing miR-140-3p and decreasing SKA2. In conclusion, circ_0008039 downregulation suppressed BC cell proliferation, migration, invasion, and glycolysis partially through regulating the miR-140-3p/SKA2 axis, providing an important theoretical basis for treatment of BC.

Haloperidol Induced Cell Cycle Arrest and Apoptosis in Glioblastoma Cells

Although several antipsychotic drugs have been shown to possess anticancer activities, haloperidol, a first-generation antipsychotic drug, has not been extensively evaluated for potential antineoplastic properties. The aim of this study was to investigate the antitumoral effects of haloperidol in glioblastoma (GBM) U87, U251 and T98 cell lines, and the effects of combined treatment with temozolomide (TMZ) and/or radiotherapy, using 4 Gy of irradiation. The viability and proliferation of the cells were evaluated with trypan blue exclusion assay and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Apoptosis, using the annexin-propidium iodide (PI), and cell cycle, cluster of differentiation (CD) expression and caspase-8 activation were measured using flow cytometry. Treatment with haloperidol significantly reduced cell viability in U87, U251 and T98 GBM cell lines. Haloperidol induced apoptosis in a dose-dependent manner, inhibited cell migration and produced an alteration in the expression of CD24/CD44. The additional effect of haloperidol, combined with temozolomide and radiation therapy, increased tumor cell death. Haloperidol was observed to induce apoptosis and to increase caspase-8 activation. In conclusion, haloperidol may represent an innovative strategy for the treatment of GBM and further studies are warranted in glioma xenograft models and other malignancies.

Improvement in the hydrodesulfurization of dibenzothiophene over supported NiMoW catalysts

Various supported NiMoW sulfided catalysts were synthetized and tested in the hydrodesulfurization (HDS) of dibenzothiophene (DBT). The influence of cetyl trimethyl ammonium bromide (CTAB) on the properties of titania, silica and Si-Ti mixed oxide, prepared by sol-gel and used as supports, was evaluated. The active metals were then sequentially co-impregnated on the carrier. For all catalysts, the Ni/[Ni(MoW)] and Mo/W atomic ratios were kept constant and equal to 0.5 and 1, respectively. In addition, the total metal content was 18 wt% for each sample. All catalysts were characterized by BET, TEM, XRD and UV-Vis. The use of CTAB as a surfactant influences the textural properties of the supports. Among the studied samples, the best catalyst was NiMoW/Si-Ti, which showed a DBT conversion of 94% after 5 h of reaction at 320 degrees C and 5.3 MPa. For comparison, a commercial NiMo/Al2O3 catalyst was used as a reference.

A Comparative Investigation on Bioactivity and Antibacterial Properties of Sol-Gel Derived 58S Bioactive Glass Substituted by Ag and Zn

The bioactive glass systems of xAg(2)O-SiO2-P2O5-CaO and xZnO-SiO2-P2O5-CaO (x = 2 and 4% mol) were successfully synthesized through sol-gel method. The effect of silver and zinc contents on the in-vitro formation of hydroxyapatite (HA), cell viability, and antibacterial properties were studied. The HA formation and its microstructure were investigated through scanning electron microscopy (SEM) and Energy-dispersive X-ray spectroscopy (EDX), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), and X-ray diffraction analysis (XRD). The results showed that the rate of crystalline HA formation on SiO2-P2O5-CaO-xAg(2)O bioactive glass, in which x = 0 and 2, (B (58S) and BA2), was higher than other specimens. The evaluation methods of 3-(4,5 dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and alkaline phosphatase (ALP) illustrated that low silver (2% Ag2O) amount had a stimulating influence on both differentiation and proliferation promotion of cells (G292 osteoblastic). Furthermore, the antibacterial investigations showed that Ag bioglass samples had better antibacterial effect in comparison to Zn bioglass samples. Accordingly, the results revealed that specimen BA2 can be a good candidate for bone tissue application due to its significant bioactivity, antibacterial potential and optimal cell viability.

First population quantification of the infestation of legumes by stored-product bruchids imported in freight containers into Europe

There is a common perception that stored-product pests cause high losses only in developing countries. This may not be true because of the import of infested commodities in freight containers, especially after the ban of the broad-spectrum fumigant methyl bromide. However, infestation quantification of such infested imports has been rare in Europe because, in addition to other factors, stored-product pests have lost their quarantine status. This work documented that heavily infested commodities may be transported to Europe from a different continent (i.e., East Africa). In particular, we present the first study to quantify the entire legume-infesting pest population that may be transported in a single freight container. The quantification of the extent of adult pest infestation was performed not by taking a limited number of samples but by sieving the content of the entire container. From the analysed freight container loaded with 24 tons of infested pinto beans, 1,101,060 adult individuals of the Mexican bean weevil, Zabrotes subfasciatus (Bohemann) (Coleoptera Chrysomelidae), were extracted. This represents a density of 45.9 adults per 1 kg of imported beans. Such a huge amount of beetles per freight container holding bean commodity is 40x more than that predicted by the theoretical estimates. The visible damage to the commodity (i.e., bean kernels with physical injury and loaded with eggs) was also profound, reaching 10%; it represents 901 440 damaged kernels per container loaded with 24 t of beans. Our findings indicate that even a single freight container transporting commodities from different continents to Europe may host pest populations exceeding one million invasive pest specimens. This may have significant importance not only in terms of the hidden contamination of human food by internally feeding and allergenic pests but also in regard to the risk of spread of entire populations and different biotypes (e.g., the transfer of genes for insecticide resistance).

Catalysis with Palladium(I) Dimers

Dinuclear Pd-I complexes have found widespread applications as diverse catalysts for a multitude of transformations. Initially their ability to function as pre-catalysts for low-coordinated Pd-0 species was harnessed in cross-coupling. Such Pd-I dimers are inherently labile and relatively sensitive to oxygen. In recent years, more stable dinuclear Pd-I-Pd-I frameworks, which feature bench-stability and robustness towards nucleophiles as well as recoverability in reactions, were explored and shown to trigger privileged reactivities via dinuclear catalysis. This includes the predictable and substrate-independent, selective C-C and C-heteroatom bond formations of poly(pseudo)halogenated arenes as well as couplings of arenes with relatively weak nucleophiles, which would not engage in Pd-0/Pd-II catalysis. This Minireview highlights the use of dinuclear Pd-I complexes as both pre-catalysts for the formation of highly active Pd-0 and Pd-II-H species as well as direct dinuclear catalysts. Focus is set on the mechanistic intricacies, the speciation and the impacts on reactivity.

Sn2B5O9Br as an Outstanding Bifunctional Material with Strong Second-Harmonic Generation Effect and Large Birefringence

The first tin (II) borate bromide, Sn2B5O9Br (SBOB), as an outstanding bifunctional material with excellent linear and nonlinear optical (NLO) performance is synthesized successfully. As far as it is known, it exhibits the largest birefringence among the reported borates (0.439 at 546 nm), even over famous birefringent materials YVO4 and TiO2. Meanwhile, it also owns a strong second harmonic generation (SHG) response of 2.4 times that of KH2PO4. Theoretical calculations display that its incredible optical properties mainly originate from the extremely intensive stereochemical activity lone pair (SCALP) of [SnO7Br2] polyhedra, which results in the enhancement of birefringence and SHG response, increasing to 2.6- and 4.8-fold, respectively, from Sn2B5O9Cl (SBOC) to SBOB. These perceptions will guide and accelerate the exploration of excellent birefringence and NLO materials in tin (II)-based compound.
