Facile Synthesis and Characterization of L-Aspartic Acid Coated Iron Oxide Magnetic Nanoparticles (IONPs) For Biomedical Applications.

Natural L-aspartic acid coated iron oxide magnetic nanoparticles (Asp@IONPs) were prepared by a one pot, in-situ and green co-precipitation method in an aqueous medium. Functionalized iron oxide magnetic nanoparticles (IONPs) were characterized by Vibrating Sample Magnetometer (VSM), X-ray diffraction (XRD), differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM) and Transmission electron microscopy (TEM) techniques. Cellular toxicity of IONPs was also investigated on HEK-293 cell lines. The results showed that the zeta potential of Asp@IONPs was about -21.1 mV and the average size was 17.80±3.09 nm. Cell toxicity results show that as prepared IONPs are biocompatible. Asp@IONPs show the possibility of using these nanoparticles in the development of in vitro and in vivo biomedical fields due to do not possess a toxic effect, good ζ-potential and related small and narrow size distribution.

Identifying Greener and Safer Plasticizers: A 4-Step Approach.

The health and economic burden of endocrine disrupting chemicals, such as the plasticizer di(2-ethylhexyl) phthalate (DEHP), is prompting industry to develop alternatives. However, the absence of requirements for manufacturers to ensure the safety of these alternatives has led to the generation of replacements that may have similar or worse effects than the original chemicals. Consequently, there is increasing recognition by scientists, regulators and industry that proactive approaches are needed to develop safe chemical substitutes. We propose a 4-step approach for the design, characterization and toxicological testing of responsible alternative chemicals that we illustrate with our ongoing studies on DEHP replacements. Our approach is comprised of: (1) the design and characterization of alternative chemicals based on innovative chemical structures and environmental considerations; (2) large-scale in vitro cell-based high throughput and selective ex vivo studies to preselect the most innocuous alternatives; (3) an acute toxicity in vivo study to rule out overt toxicity of the selected candidates; and (4) an in utero and lactational exposure study comparing the effects of selected candidates to those currently in use, emphasizing commonly described phenotypes after exposure to the latter. Using this 4-step approach, we have identified 2 alternative chemicals displaying good plasticizing properties, better biodegradability, and less leaching than DEHP without any apparent toxicity in vivo. This process has thus far proven useful in the proactive identification of responsible chemical replacements for DEHP.

Enhanced Desiccation Tolerance In Mature Cultures Of The Streptophytic Green Alga Zygnema circumcarinatum Revealed By Transcriptomics.

Desiccation tolerance is commonly regarded as one of the key features for the colonization of terrestrial habitats by green algae and the evolution of land plants. Extensive studies, focused mostly on physiology, have been carried out assessing the desiccation tolerance and resilience of the streptophytic genera Klebsormidium and Zygnema. Here we present transcriptomic analyses of Zygnema circumcarinatum exposed to desiccation stress. Cultures of Z. circumcarinatum, grown in liquid medium or on agar plates, were desiccated at ∼86% relative air humidity until Y(II) ceased. In general, the response to dehydration was much more pronounced in Z. circumcarinatum, cultivated in liquid medium for one month, compared to filaments grown on agar plates for seven and twelve months. Cultivation on solid medium enables the alga to acclimate to dehydration much better and an increase in desiccation tolerance was clearly correlated to increased culture age. Moreover, gene expression analysis revealed that photosynthesis was strongly repressed upon desiccation treatment in the liquid culture while only minor effects were detected in filaments cultivated on agar plates for seven months. Otherwise, both samples showed an induction of stress protection mechanisms such as ROS scavenging (Early light-induced proteins, glutathione metabolism) and DNA repair as well as the expression of chaperones and aquaporins. Additionally, Z. circumcarinatum, cultivated in liquid medium, upregulated sucrose synthesizing enzymes and strongly induced membrane modifications in response to desiccation stress. These results corroborate the previously described hardening and associated desiccation tolerance in Zygnema in response to seasonal fluctuations in water availability.

Accomplishing reform: successful case studies drawn from the health systems of 60 countries.

Healthcare reform typically involves orchestrating a policy change, mediated through some form of operational, systems, financial, process or practice intervention. The aim is to improve the ways in which care is delivered to patients. In our book 'Health Systems Improvement Across the Globe: Success Stories from 60 Countries', we gathered case-study accomplishments from 60 countries. A unique feature of the collection is the diversity of included countries, from the wealthiest and most politically stable such as Japan, Qatar and Canada, to some of the poorest, most densely populated or politically challenged, including Afghanistan, Guinea and Nigeria. Despite constraints faced by health reformers everywhere, every country was able to share a story of accomplishment-defining how their case example was managed, what services were affected and ultimately how patients, staff, or the system overall, benefited. The reform themes ranged from those relating to policy, care coverage and governance; to quality, standards, accreditation and regulation; to the organization of care; to safety, workforce and resources; to technology and IT; through to practical ways in which stakeholders forged collaborations and partnerships to achieve mutual aims. Common factors linked to success included the 'acorn-to-oak tree' principle (a small scale initiative can lead to system-wide reforms); the 'data-to-information-to-intelligence' principle (the role of IT and data are becoming more critical for delivering efficient and appropriate care, but must be converted into useful intelligence); the 'many-hands' principle (concerted action between stakeholders is key); and the 'patient-as-the-pre-eminent-player' principle (placing patients at the centre of reform designs is critical for success).

2D TM scattering problem for finite dielectric objects in a dielectric stratified medium employing Gabor frames in a domain integral equation.

We present a method to simulate two-dimensional scattering by dielectric objects embedded in a dielectric layered medium with transverse magnetic polarization through a domain integral equation formulation. A mixed spatial-spectral discretization is employed with both a spatial and a spectral representation along the direction of the layer interfaces. In the spectral domain, a discretization on a path through the complex plane is used on which the Green function is well behaved. To calculate the field-material interaction in the spatial domain, an auxiliary field is employed similar to the Li factorization rules. Numerical results show that this auxiliary-field formulation significantly improves accuracy, compared to a formulation that directly employs the electric field.

Illuminations that improve color discrimination ability of people with red-green color vision deficiency.

In this research, three illuminants that improve color discrimination ability of people with red-green color vision deficiency were developed. The illuminants are close to daylight-colored and were produced by using spectral optimization. Deutans were the focus of this research, but a few protans were also tested for reference. The illuminants were produced by combining different types of LEDs, and their effects were tested with several test subjects with and without color vision deficiency using the Ishihara color vision test and the Farnsworth Panel D-15 test. The illuminant with the most powerful effect provided near perfect results with the Ishihara test for deutans, while the other two illuminants produced smaller improvements. The Farnsworth Panel D-15 test produced results that were similar to the Ishihara test though generally the color discrimination of blue hues was weaker under the most powerful illuminant.

NH2-coordinately immobilized tris(8-quinolinolato)iron onto the silica coated magnetite nanoparticle: Fe3O4@SiO2-FeQ3 as a selective Fenton-like catalyst for clean oxidation of sulfides.

A green, robust and eco-friendly procedure for the oxidation of aromatic organic sulfides to sulfones using H2O2 catalyzed by NH2-coordinately immobilized tris(8-quinolinolato)iron onto the silica coated magnetite (Fe3SiO6) has been developed. Physicochemical properties of the resulting nanoparticles were investigated by means of techniques including X-ray diffraction, scanning electron microscopy, thermogravimetric analysis, vibrating sample magnetometer, atomic adsorption spectroscopy and FT-IR spectroscopy. The catalytic activity of sulfides oxidation showed that this atom-economical protocol provided great yields of various sulfones and allowed the sulfide function reaction conducting under the mild conditions thus to prevent the sulfide being over-oxidized to sulfoxides. The Fe3O4@SiO2-FeQ3 catalysts are magnetically separable and kept stable after recycling for 7 consecutive runs without detectable activity loss.

Green electrospun and crosslinked poly(vinyl alcohol)/poly(acrylic acid) composite membranes for antibacterial effective air filtration.

Air pollution has become a major environmental concern given the ever increasing levels of particulate matter (PM) and the increased in treatment-resistant bacterial and viral strains. Major efforts are therefore required into the development of air filtration and purification technology as well as novel, alternative antiviral and antibacterial treatment modalities. Here, we report an environmentally friendly method for the generation of multifunctional poly(vinyl alcohol)/poly(acrylic acid) (PVA-PAA) composite membranes via green electrospinning and thermal crosslinking. Superhydrophobic silica nanoparticles were then incorporated into the fibers resulting in a rough surface, after which AgNO3 was introduced, resulting in the formation of Ag nanoparticles through UV reduction. The PVA-PAA-SiO2-Ag NPs membranes were found to possess high air filtration performance (with >98% filtration efficiency for PM2.5) as well as potent antibacterial and antiviral activities. The green synthesis approach avoids the use of hazardous organic solvents, thereby bypassing any potential toxicity concerns caused by organic solvent residues. These newly designed PVA-PAA-SiO2 NPs-Ag NPs nanofibrous membranes with many superior features (e.g. high filtration efficiency, high tensile strength, biological compatibility, and antibacterial properties) can be applied in eco-friendly air filtration materials, in particular for personal air filtration devices.

Magnetic iron oxide/phenylsulfonic acid: A novel, efficient and recoverable nanocatalyst for green synthesis of tetrahydrobenzo[b]pyrans under ultrasonic conditions.

A novel magnetic iron oxide supported phenylsulfonic acid (Fe3O4@Ph-SO3H) with core-shell structure is prepared, characterized and applied as efficient nanocatalyst for green synthesis of tetrahydrobenzo[b]pyrans. The Fe3O4@Ph-SO3H was prepared via modification of magnetic iron oxide cores with 1,4-bis(triethoxysilyl)benzene (BTEB) followed by sulfonation of aromatic rings. The Fe3O4@Ph-SO3H was characterized using FTIR, TGA, PXRD, SEM, TEM, VSM and EDX techniques. This was effectively applied for synthesis of tetrahydrobenzo[b]pyrans in water as green solvent at room temperature under ultrasonic conditions. The products were obtained in high to excellent yields at short times. The recoverability, reusability and durability of this nanocatalyst were studied under applied reaction conditions.

A force-based mechanistic model for describing activated sludge settling process.

Sludge settling as the last step in the biological wastewater treatment process substantially affects the system performance, and thus the design and control optimization of the sludge settling process has been frequently investigated with mathematical modeling tools. So far, these models are developed on the basis of the solid flux theory with numerous parameters and complicated boundary conditions, and their prediction results are often unsatisfactory. In this work, a new force-based mechanical model with five parameters was developed, in which five forces were adopted and Newton's law, rather than the flux theory, was used to describe the sludge settling process. In such a model, the phase interactions were taken into account. New functions of hydrodynamic drag, solids pressure and shear stress were developed. Model validation results demonstrate that both batch and continuous sludge settling processes could be accurately described by this model. The predictions of this model were more accurate than those of flux theory-based models, suggesting its advantages in understanding sludge settling behaviors. In addition, this mechanistic model needed to input 5 parameters and set 1 boundary condition only, and could be directly executed by commercial computational fluid dynamics software. Thus, this force-based model provides a more convenient and useful tool to improve the activated sludge settling design and operation optimization.
