Conversion of biomass energy of dewatered oily sludge to electricity is the rate-limiting process in bioelectrochemical system (BES). In this study, 2mgg(-1) rhamnolipids were added to dewatered oily sludge, resulting in a significant enhancement in maximum power density from 3.84±0.37 to 8.63±0.81Wm(-3), together with an increase in total organic carbon (TOC) and total petroleum hydrocarbon (TPH) removal from 24.52±4.30 to 36.15±2.79mgg(-1) and 29.51±3.30 to 39.80±2.47mgg(-1), respectively. Rhamnolipids can also enhance the solubilization and promote the hydrolysis of dewatered oily sludge with increases in SOCD from 14...

BACKGROUND/AIMS: Increasing evidence suggests that T-UCRs are involved in the development of cancer. In this study, we evaluated the role of a macrophage-derived T-UCR, uc.306, in the prognosis of hepatitis B (HBV)-related hepatocellular carcinoma (HCC). METHODS: The uc.306 was obtained by screening microassay data obtained during the polarization of U937 cells from the M2 to M1 phenotype. Uc.306 and macrophage molecule markers were detected by qPCR. Immunohistochemical (IHC) assays were used to examine the M1/M2 status of 90 paired HCC tissues...

We developed ReaxFF parameters for phosphorus and hydrogen to give a good description of the chemical and mechanical properties of pristine and defected black phosphorene. ReaxFF for P/H is transferable to a wide range of phosphorus and hydrogen containing systems including bulk black phosphorus, blue phosphorene, edge-hydrogenated phosphorene, phosphorus clusters and phosphorus hydride molecules. The potential parameters were obtained by conducting global optimization with respect to a set of reference data generated by extensive ab initio calculations...

Breast cancer human cells culture as spheroids develop autophagy and apoptosis, which promotes Trastuzumab resistance in HER2 overexpressing cells. Our aim was to study the association of the hostile environment developed in 3D with the breast cancer stem cells population and the HER2 modulation. Human mammary adenocarcinoma cell lines were cultured as spheroids using the hanging drop method. We generated hypoxia conditions by using a hypoxic chamber and CoCl2 treatment. Breast cancer stem cells were measured with mammosphere assays, the analysis of CD44 + CD24(low) population by flow cytometry and the pluripotent gene expression by RT-qPCR...

Adjuvant chemotherapy improves survival in patients with resected pancreatic cancer but the optimal regimen remains unclear. We aim to compare all possible adjuvant chemotherapy in terms of overall survival and toxic effects. Pubmed, Trial registries and Cochrane library databases for randomized controlled trials were searched until November 2016. Thirteen trials were included for network analysis and the hazard ratios (HRs) for survival and odds ratios for toxic effects were assessed via Aggregate Data Drug Information System software...

Our previous observations indicated that extractable organic matter (EOM) from PM2.5 induced malformations in the heart of zebrafish embryos by activating AhR and inhibiting canonical Wnt/β-catenin signal pathway. As a nutritional factor, folic acid (FA) is reported to prevent cardiac defects during embryo development. Hence, we hypothesize that FA may prevent PM2.5-induced heart defects by interfering with AhR and Wnt/β-catenin signaling pathways. Our results showed that FA supplementation alleviated the EOM-induced heart defects in zebrafish embryos, and both AhR inhibitor CH223191 and Wnt activator CHIR99021 enhanced the protective efficiency of FA...

The single-crystal to single-crystal (SC-SC) transformation from a 1D coordination chain to a 3D coordination network, which is triggered by both solvent and anion exchanges, has been revealed to suffer from a tandem mechanism as proved by isolation of the intermediate state. The resulting porous crystalline material shows a high efficiency for the capture of dichromates (207 mg g(-1)) via the SC-SC anion-exchange.

The lack of aroma and natural taste is a critical problem in production and consumption of instant green teas. A method to prepare instant green teas high in-natural-aroma and low-caffeine by the novel column chromatographic extraction with gradient elution is reported. This method simultaneously extracted aroma (or volatile) and non-aroma compounds from green tea. Green tea was loaded into columns with 2.0-fold of petroleum ether (PE): ethanol (8:2). After standing for 3 h until the aroma compounds dissolved, the column was sequentially eluted with 3...

We investigated the 47-kDa outer membrane protein (OMP), which is a periplasmic serine protease and an antigenic major surface protein of Orientia tsutsugamushi, as a vaccine candidate. We developed a conventional subunit vaccine expressing recombinant 47-kDa OMP (rec47) and a DNA vaccine (p47). In mouse immunization experiments, intranasal immunization with rec47 alone or with rec47 plus heat-labile enterotoxin B subunit from Escherichia coli or plus cholera toxin (CT) as adjuvants induced a higher amount of rec47-specific antibodies than intramuscular immunization with p47 alone or with p47 plus pBOOST2-samIRF7/3 (pB) as adjuvant...

We designed and demonstrated a single-legged or unipedal walker that has a "cleat" that allows it to persistently associate with a track and make autonomous decisions about movement. The walker is highly processive over long periods of time, as shown by its movement over a microparticle surface suffused with substrate. The simple design can be readily optimized on the basis of simple energetic considerations. The walker can be used for signal amplification and should prove especially valuable for programming amorphous computations within chemical reaction networks...

Hang Li, Akos Vertes
Most electrospray based ambient ionization techniques, e.g., laser ablation electrospray ionization (LAESI), utilize a fixed spray solution composition. Complex samples often contain compounds of different polarity that exhibit a wide range of solubilities in the electrospray solvent. Thus, the fixed spray solution composition limits the molecular coverage of these approaches. Two-barrel theta glass capillaries have been used for the rapid mixing of two solutions for manipulating fast reactions including protein folding, unfolding, and charge state distributions...

An efficient and convenient protocol for the synthesis of 2H-chromenones has been developed. In the presence of (t)BuOK in DMF, good to excellent yields of various chromenones were obtained from the corresponding salicylaldehydes and arylacetonitriles. No protection of inert gas atmosphere is required here.

Metal-organic frameworks (MOFs) are a class of modular, crystalline, and porous materials that hold promise for storage and transport of chemical cargoes. Though MOFs have been studied in bulk forms, ways of deliberately manipulating the external surface functionality of MOF nanoparticles are less developed. A generalizable approach to modify their surfaces would allow one to impart chemical functionality onto the particle surface that is independent of the bulk MOF structure. Moreover, the use of a chemically programmable ligand, such as DNA, would allow for the manipulation of interparticle interactions...

Rhenium disulfide (ReS2) has attracted immense interest as a promising two-dimensional material for optoelectronic devices owing to its outstanding photonic response based on its energy band gap's insensitivity to the layer thickness. Here, we theoretically calculated the electrical band structure of mono-, bi-, and tri-layer ReS2 and experimentally found the work function to be 4.8 eV, which was shown to be independent of the layer thickness. We also evaluated the contact resistance of a ReS2 field-effect transistor (FET) using a Y-function method with various metal electrodes, including graphene...

PURPOSES: We previously showed that polyphenol-rich blackcurrant extract (BCE) showed a hypocholesterolemic effect in mice fed a high fat diet. As direct cholesterol removal from the body via the intestine has been recently appreciated, we investigated the effect of BCE on the modulation of genes involved in intestinal cholesterol transport using Caco-2 cells as an in vitro model. METHODS: Caco-2 cells were treated with BCE to determine its effects on mRNA and protein expression of genes important for intestinal cholesterol transport, low-density lipoprotein (LDL) uptake, cellular cholesterol content, and cholesterol transport from basolateral to apical membrane of Caco-2 cell monolayers...

Obesity is the major risk factor for type 2 diabetes, cardiovascular disorders, and many other diseases. Adipose tissue inflammation is frequently associated with obesity and contributes to the morbidity and mortality. Dedicator of cytokinesis 2 (DOCK2) is involved in several inflammatory diseases, but its role in obesity remain unknown. To explore the function of DOCK2 in obesity and insulin resistance, wild-type (WT) and DOCK2 deficient (DOCK2-/-) mice were given chow or high-fat diet (HFD) for 12 weeks followed by metabolic, biochemical and histologic analyses...
