Plants reproductive phase, when grain yield and consequently farmers' investment is most in jeopardy, is considered as the most sensitive stage to drought stress. In this study, we aimed to explore the proteomic response of wheat anther at meiosis stage in a drought tolerant, Darab, and susceptible, Shiraz, wheat genotypes. Wheat plants were exposed to drought stress at meiosis stage for four days under controlled environmental conditions. Then, anthers from both genotypes were sampled, and their proteomes were examined via quantitative proteomics analysis...

In this study, a new zinc chloride (ZnCl2) impregnated activated carbon (Zn-AC) was prepared from oak charcoals as low-cost material and used as adsorbent for tetracycline (TC) adsorption. The Zn-AC was characterized using field emission-scanning electron microscope, powder X-ray diffraction, and CHNS-O analyses. Specific surface area of the adsorbent was also measured using the Brunauer, Emmett and Teller (BET) isotherm model. The TC adsorption onto the Zn-AC was investigated as a function of solution pH, adsorbent dosage, and inorganic cations (Li(+), K(+), Mg(2+), Ca(2+), Ni(2+), and Fe(3+)) and anions (HCO3(-), NO3(-) and SO4(2-)) that could interfere in the adsorption of TC...

Purified terephthalic acid (PTA) plant of a petrochemical unit generates wastewater having high pollution load. Acid treatment of this wastewater reduces the chemical oxygen demand (COD) load by more than 50%, still leaving substantial COD load (>1500 mg/L) which should be removed. The present study reports on the use of a bio-waste-adsorbent bagasse fly ash (BFA) for the reduction of COD and other recalcitrant acids from this wastewater. The BFA showed basic character and was mesoporous with a BET specific surface area of 82...

BET bromodomain inhibitors are very promising novel anticancer agents, however, single therapy does not cause tumor regression in mice, suggesting the need for combination therapy. After screening a library of 2697 small molecule compounds, we found that two classes of compounds, the quinone-containing compounds such as nanaomycin and anti-microtubule drugs such as vincristine, exerted the best synergistic anticancer effects with the BET bromodomain inhibitor JQ1 in neuroblastoma cells. Mechanistically, the quinone-containing compound nanaomycin induced neuroblastoma cell death but also activated the Nrf2-antioxidant signaling pathway, and the BET bromodomain proteins BRD3 and BRD4 formed a protein complex with Nrf2...

The optimal strategy for the safe disposal of large amounts of hydrophyte biomass with enriched levels of N and P is challenging. In this study, we proposed and illustrated a facile pyrolysis approach to prepare an N, P-dually doped porous carbon (NPC) material with robust energy storage performance using a thermochemical self-doping process and a widely distributed hydrophyte biomass (Typha angustifolia). As a supercapacitor electrode material for electrochemical energy storage, the NPC shows a maximum capacitance of 257 F g-1 and energy density of 19...

The organometallic synthon trans-[p-MeSC6H4C≡C-Pt(PMe3)2-C≡CC6H4SMe] (L1) reacts with CuX (X = Cl, Br, I) in PrCN and PhCN to form 1D- or 2D-coordination polymers (CP) with a very high degree of variability of features. The copper-halide unit can be either the rhomboids Cu2X2 fragments or the step cubane Cu4I4. The CP's may also incorporate a crystallization solvent molecule or not, which may be coordinated to copper or not. Their characterizations were performed by X-ray crystallography, thermal gravimetric analysis (TGA), and IR, absorption, and emission spectra as well as photophysical measurements in the presence and absence of solvent crystallization molecules...

In situ formation of nitrogen-doped carbon nanoparticles on hollow carbon spheres (NHCSs) were successfully realised via a simple, scalable emulsion polymerization route using melamine as the nitrogen precursor, followed by thermal treatment at 1000 °C in N2. All NHCSs show large BET specific surface areas (648.2-837.7 cm(2) g(-1)) and pore volumes (0.91-1.16 cm(3) g(-1)), evidently superior to N-free hollow carbon spheres (HCSs) (524.3 cm(2) g(-1) and 0.48 cm(3) g(-1), respectively). This unique nanocomposite has hierarchical micro-/mesoporosity (1...

A hierarchical structure of NiCo2O4@rGO composite has been fabricated, with its structure and morphology well characterized by XRD, TEM, XPS and BET. The results proved that the NiCo2O4 nanosheets grow uniformly on both sides of the graphene sheets. In batch adsorption experiments, the effects of equilibrium time, pH and temperature on uranium(vi) adsorption were investigated. The main results show that the NiCo2O4@rGO composite has a higher affinity towards the uptake of uranium(vi) from aqueous solutions...

PURPOSE: The bromodomain and extra-terminal domain (BET) family proteins are epigenetic readers for acetylated histone marks. Emerging BET bromodomain inhibitors have exhibited antineoplastic activities in a wide range of human cancers through suppression of oncogenic transcription factors, including MYC. However, the preclinical activities of BET inhibitors in advanced solid cancers are moderate at best. To improve BET-targeted therapy, we interrogated mechanisms mediating resistance to BET inhibitors in colorectal cancer (CRC)...

We report a facile method to tune TiO2 nanoparticles' morphology by modifying and an acid-catalyzed sol-gel synthesis with Pluronic P123. Synthesized particles were characterized by transmission electron microscopy, BET analysis, and X-ray diffraction spectroscopy. XRD analysis revealed a high anatase content while BET measurements showed that porous volume strongly depends on the amount of P123. We demonstrate that high amounts of P123 increase particle's aspect-ratio from spherical to rod-shape morphology...

A modified biomacromolecule, chitosan-thiosemicarbazide framework (TSCS) as an adsorbent for Cu(II) was prepared from dialdehyde chitosan through condensation reaction with thiosemicarbazide, stabilized by the reduction reaction with sodium borohydride. TSCS was characterized by means of FT-IR and XPS. Surface morphologies were studied by FESEM and BET, which revealed the highly macro porous structure. The thermal analyses was done through TGA showing much stable chemical configuration at about ≥400°C. The experimental equilibrium data was evaluated by Langmuir, Freundlich and Dubinin-Radushkevich isotherm models...
