Peony seed oil microemulsion that enhances the antioxidant, antitumor, and antibacterial activities of berberine hydrochloride

Peony seed oil (PSO) is an edible oil with high nutritional value. In this study, a stable oil-in-water microemulsion (Blank-ME) was prepared using PSO as the oil phase, and RH 60-CO 40-Span 80-PEG 200 (RCSP) as surfactants and co-surfactants. The physicochemical properties and stability of Blank-ME samples with different water mass fractions and RCSP/PSO ratios were studied. The average particle size and polydispersity index (PDI) decreased as the water mass fraction increased, and the PDIs of the samples containing PSO were all lower than 0.3. The visual appearance, average particle size, and PDI indicated that Blank-ME samples had good environmental stability when they were centrifuged at 10,000 r/min for 30 minutes, stored at 55 °C for 12 hours, and stored at 4 °C for 10 days. The Blank-ME could effectively encapsulate berberine hydrochloride (BH), and a BH-ME was prepared. The average particle sizes of all BH-ME samples were less than 35.00 nm, and increased as the BH concentration was increased from 0.05 to 1.0 mg/g. The system prepared with a BH concentration of 1.0 mg/g had good structural stability under different storage temperatures (4 °C, 25 °C, and 37 °C). BH and Blank-ME showed good synergy effects (32.87%) of the DPPH• scavenging capacity after 24 hours of reaction. The antitumor and antibacterial activities also exhibited possible synergism between BH and Blank-ME. These findings are positive for the application of MEs and BH in pharmaceutical, food, and other industries.

Establishment of low-carbon microbial network to enhance phenol removal in microbial electrochemical systems with whole process carbon source limitation

Microbial electrochemical system employs electroactive microorganisms as catalysts to generate energy and remove pollutants. The formation of electroactive biofilms (EABs) is essential to efficient pollutant removal as it provides the opportunity for microbial interspecies interaction. Bioavailable carbon source serves as the material basis for the energy supply, and its concentration plays a decisive role in EAB formation and pollutant removal. Unfortunately, the mechanisms of how bioavailable carbon source concentration affects microbial interspecies communication and metabolic activity during EAB formation and pollutant degradation have not been thoroughly investigated. Here, phenol was used as the pollutant to evaluate the performance of EABs formed at different acetate loadings (0.2, 0.5, and 1.0 g/L, marked as EAB-0.2 to 1.0). More phenol degrading microorganisms were enriched in EAB-0.2, achieving better phenol removal. Limited bioavailable carbon source forced microorganisms to adjust metabolites, thus facilitating the interspecies interaction. The close linkage between the up-regulated metabolic pathways facilitated the tricarboxylic acid cycle, leading to faster substrate metabolism. We demonstrated that EAB cultivated in a limited organic environment was more active in pollutant removal, which was essential to guide the application of MES in industrial wastewater treatment.

PH buffering of nutrient solutions with differing water quality in small-scale hydroponic systems

Nutrient solution pH and water quality are challenges faced by small-scale hydroponic growers. The objective was to evaluate the use of the pH buffer 2-(N-morpholino) ethanesulfonic acid (MES) as an initial dose to simplify pH management in small-scale hydroponic systems, and its effectiveness within the range of alkalinity that commonly occurs in irrigation water. Two experiments tested pH buffering capacity in response to acid-base titrations, and when growing compact tomatoes (Lycopersicon esculentum) over a nine-week cycle. MES was applied at 0 to 10 mM in water and nutrient solutions at five water qualities ranging from 4 to 295 mg.L−1 CaCO3 alkalinity. Solution buffering increased with addition of fertilizer, increasing doses of MES, and increasing water alkalinity. The MES decreased pH variability over time in all water qualities, without affecting plant growth or causing nutritional disorders. The pH of solutions without MES ranged from 4.5 to 8.0 over the growing cycle, whereas in 10 mM MES solutions it ranged from 5.7 to 7.0 for alkalinities 0 to 146 mg.L−1 CaCO3 and reached 7.6 for 295 mg.L−1 CaCO3. Titration of nutrient solutions after tomato growth indicates that MES acid-buffering capacity was partially consumed along the trial, which was probably the result of MES decomposition or interaction with acids and bases in solution. Results indicate that a single 10 mM MES application could be used by small-scale hydroponic growers to provide acceptable pH buffering for low to moderate alkalinity levels, but initial pH adjustment may be necessary and solution pH may still increase with high alkalinity.

Human-centered performance management in manual assembly

This paper presents results from an ongoing empirical study that investigates the effect of human-centered performance management with regard to operational performance and work motivation of shop floor workers. The approach is based on gamified information provisioning. To date, the concept of gamification has been applied in numerous fields, yet hardly any related work provides empirical findings for the production environment. Based on previous approach, we realized our approach prototypically as an MES application. Then, we integrated our application into a business game simulation. The study design builds on an application scenario in manual assembly. Two treatment groups were defined for investigation. Qualitative observations show that the provision of gamified metrics-based information proves to be a motivation driver.

Repeated Applications of Mesotrione and Napropamide on New Cranberry Plantings

To evaluate the weed control provided by various combinations of PRE applications of napropamide (Nap) and POST applications of mesotrione (Mes) in newly planted and 1-yr-old cranberry vines, six 2-yr experiments were conducted during 2009-2012. Three sites were treated in the year of planting plus the subsequent year (called “new plantings”) and three sites were treated in their second year of growth plus the subsequent year (called “second-year plantings”). Ten treatments, delivered in 3,735 L ha−1 water, were administered each year: Nap at 3.36 kg ai ha−1 applied once, twice, thrice or once followed by (fb) one application of Mes at 210 g ai ha−1; Nap at 5.04 kg ha−1applied once, twice or once fb one application of Mes at 210 g ha−1; Mes at 210 g ha−1 applied once or twice; and nontreated. At new planting sites, plots receiving treatments other than a single Nap application had less total weed biomass compared to nontreated plots. At second-year plantings, all herbicide-treated plots had less total weed biomass than nontreated plots; in addition, plots receiving Mes-only treatments had less total weed biomass than Nap-only treatments. Correlation analysis indicated that monocot biomass production was the primary positive predictor for total weed biomass. Herbicides did not adversely affect cranberry biomass production but overall vine colonization was poor for four of the six sites indicating that other factors, including cultivar choice, planting method, and water management, may play a larger role in rapid cranberry vine colonization than the suppression of initial weed biomass. Given the complementary range of efficacy for Nap and Mes, a combination PRE-POST herbicide program of a low rate of Nap fb Mes may be the most cost-beneficial program in many instances. If cost is a limiting factor, applying a single application of Mes to a new planting should be included as a component of cranberry bed establishment since this practice consistently resulted in significantly less initial weed biomass compared to areas left nontreated.

Based on Grid of Reconfigurable Manufacturing Execution System

The use of grid manufacturing system, has become the trend of modern manufacturing technology. With reference to the idea of component design for workshop production business, a workflow and multi-agent based Grid of Reconfigurable of Manufacturing Execution System (GRMES) is presented. The configurable workshop production business can be handled, and the MES application system can correspondingly adjust with its change. The KQML is expanded to compensate for its description ability in the Workflow management system. XML is applied to support the data flow in GRMES, format the dispatched tasks and KQML, which can securely and concisely transfer different data among the workflow engines, agents and application on the GRMES. GRMES improves the problems such as adaptability and reconstructivity, which exist in the traditional MES.

MES [2-(N-morpholine)-ethane sulphonic acid] buffer promotes the growth of external hyphae of the arbuscular mycorrhizal fungus Glomus intraradices in an alkaline sand

In this work we investigated the hypothesis, suggested by unpublished experiments carried out previously, that application of MES [2-(N-morpholino)-ethane sulphonic acid] buffer to the substrate of plants hosting the arbuscular mycorrhizal fungus Glomus intraradices might favour the growth of external hyphae. The substrate of Trifolium pratense plants, with or without G. intraradices inoculum, was treated twice weekly, between weeks 5 and 11 of growth, plant with distilled water, P-supplemented 10% Hewitt nutrient solution (H+P), 51mM in H+P or 1mM TRIS-HCl in H+P. MES buffer increased the length of external G. intraradices hyphae and the density of propagules in the substrate, but plant growth was not affected. Although both TRIS-HCl and MES caused substrate pH to fall (from 8.51 to 7.35 and 7.17, respectively), only MES induced a significant increase in external hypha length. We conclude that the effect of MES on external hypha length was not due to plant growth or to substrate pH per se.
