Effect of Consumption of Artesunate and/or Palm Wine on Serum Electrolytes, Urea, Creatinine and Estimated Glomerular Filtration Rate

Aim: Artesunate (artemisinin derivative) prophylaxis is one filtration rate (eGFR) were assessed before and after 7 days of treatment. Participants were all Africans (n=30) and were the staff of the Faculty of Basic Medical Sciences, University of Calabar. Results: Significant increase (p<0.05) in serum Na + and a decrease in K + levels above pretreatment values were observed in the palm wine and artesunate group. Creatinine concentrations of both palm wine and artesunate, as well as artesunate only groups, were significantly increased above control values. Creatinine clearance rate was significantly reduced (p<0.05) in the palm wine and artesunate group. Conclusion: Combined consumption of fresh palm wine and artesunate decreased creatinine clearance rate as well as eGFR. This decrease may be followed by a decline in the other renal function indices.
Modified local carbonate mineral as deoxygenated catalyst for biofuel production via catalytic pyrolysis of waste cooking oil

Malaysian Dolomite with 5% dispersion of nickel has shown potential deoxygenation catalyst due to high capacity in removing oxygen compound and produce high quality of biofuel with desirable lighter hydrocarbon (C8−C24). The modified dolomite catalyst showed enhanced physicochemical properties by surface area increment and average pore diameters reduction. The performance of this modified catalyst was compared with two commercial catalysts in catalytic pyrolysis of Waste Cooking Oil. The liquid product showed similar chemical composition of biofuel in the range of gasoline, kerosene and diesel fuel. Furthermore, this modified Malaysian Dolomite catalyst showed high reactivity with 68.0 wt% of waste cooking oil conversion, 36.4 wt% of biofuel generated, 78.0% yield in C8−C24 of pyrolysis oil and 55.2% selectivity in biodiesel. Thus, local modified calcined carbonated material has a potential to be as a deoxygenated catalyst in converting waste cooking oil into biofuel.
Functions of the Laplacian Matrix With Application to Distributed Formation Control

In this article, we study a class of matrix functions of the combinatorial Laplacian that preserve its structure, i.e., that define matrices, which are positive semidefinite and which have zero row-sum and nonpositive off-diagonal entries. This formulation has the merit of presenting different incarnations of the Laplacian matrix that have appeared in recent literature in a unified framework. For the first time, we apply this family of Laplacian functions to consensus theory, and we show that they leave the agreement value unchanged and offer distinctive advantages in terms of performance and design flexibility. The theory is illustrated via worked examples and numerical experiments featuring four representative Laplacian functions in a shape-based distributed formation control strategy for single-integrator robots.
Improving Emergency Department Use of Safety-Net Antibiotic Prescriptions for Acute Otitis Media

Objectives Acute otitis media (AOM) is the most common reason for pediatric antibiotic prescriptions. The 2013 American Academy of Pediatrics' AOM guidelines recommend observation for nonsevere AOM. Our aim was to increase the percentage safety-net antibiotic prescription (SNAP) offered to patients 6 months of age or older diagnosed with AOM in 2 pediatric emergency departments (EDs) from a baseline of 0.5% to 15% in 20 months. Methods This is a quality improvement study at a quaternary pediatric medical center with 2 locations, both with EDs. A random chart review revealed that 27.5% of patients diagnosed with AOM in the ED would qualify for a SNAP, but only 0.5% were offered it. Quality improvement interventions were designed to improve safety-net antibiotic prescribing. Both EDs conducted multiple interventions, including algorithm development, provider education, and electronic medical record aids. The primary outcome measure was the percentage of patients offered a SNAP for AOM. Results A total of 8226 children 6 months of age or older were diagnosed with AOM in our 2 EDs during the 20-month intervention period. The percentage offered a SNAP increased at both EDs. One ED had a single shift in the mean to 7.9%, whereas the other had 2 shifts in the mean, an initial shift to 5.1% and a second to 7.3%. Providers consistently used the algorithm and electronic medical record aids. Conclusions Safety-net antibiotic prescriptions in conjunction with parent education was effective in reducing the use of immediate antibiotic prescriptions in children with AOM in 2 pediatric EDs. Offering a SNAP can reduce unnecessary use of antibiotics, which in turn may decrease antibiotic-related adverse events and antibiotic resistance.
Epoxidized Natural Rubber/Polyvinyl Chloride/Microcrystalline Cellulose (ENR/PVC/MCC) Composite Membrane for Palm Oil Mill Effluent (POME) Treatment

Epoxidized natural rubber/polyvinyl chloride/microcrystalline cellulose (ENR/PVC/MCC) composite membranes were prepared and used to treat palm oil mill effluent (POME). The loadings of MCC were varied at 0, 5, 10 and 15 w/w%. The increment of MCC loads has intensified the hydroxyl peak of the membranes in FTIR spectrum, indicating the increase in membrane hydrophilicity. MCC acted as a pore forming agent since the ENR/PVC/10% MCC gave the highest water flux and well-distributed pores. After first treatment of POME, the levels of chemical oxygen demand (COD), biochemical oxygen demand (BOD) and total suspended solid (TSS) were reduced to 99.9%, 70.3%, and 16.9%, respectively. These data showed that ENR/PVC/MCC membrane has the potential to treat POME.
Fiber orientation effects on the non-linear vibrations for a microstructure-dependent tapered plate containing an arbitrarily located crack

Abstract Non-linear vibrations in a cracked orthotropic plate with non-uniform thickness as affected by the fiber orientation have been studied analytically. Linear variation in the plate thickness is assumed in one and two directions. The governing equation of the tapered orthotropic plate is derived using the equilibrium principle. The effect of microstructure is incorporated using the modified couple stress theory. The effect of partial crack on the plate dynamics is incorporated in the form of in-plane forces and bending moments. It has been found that vibration characteristics are affected by the taper parameters and fiber direction for a cracked orthotropic plate.
Liquid Metal Droplets Wrapped with Polysaccharide Microgel as Biocompatible Aqueous Ink for Flexible Conductive Devices

Nanometerization of liquid metal in organic systems can facilitate deposition of liquid metals onto substrates and then recover its conductivity through sintering. Although having broader potential applications, producing stable aqueous inks of liquid metals keeps challenging because of rapid oxidation of liquid metal when exposing to water and oxygen. Here, a biocompatible aqueous ink is produced by encapsulating alloy nanodroplets of gallium and indium (EGaIn) into microgels of marine polysaccharides. During sonicating bulk EGaIn in aqueous alginate solution, alginate not only facilitates the downsizing process via coordination of their carboxyl groups with Ga ions but also forms microgel shells around EGaIn droplets. Due to the deceasing oxygen‐permeability of microgel shells, aqueous ink of EGaIn nanodroplets can maintain colloidal and chemical stability for a period of >7 d. Crosslinked alginate‐gel with tunable thickness can retard the generation and release of toxic cations, thereby affording high biocompatibility. The soft alginate shells also enable to recover electric conductivity of EGaIn layers by “mechanical sintering” for applications in microcircuits, electric‐thermal actuators, and wearable sensors, offering huge potential for electronic tattoos, artificial limbs, electric skins, etc.
2D hybrid interlayer of electrochemically exfoliated graphene and Co(OH)2 nanosheet as a bi-functionalized polysulfide barrier for high-performance lithium–sulfur batteries

Lithium sulfur (Li–S) batteries have attracted much attention because of high energy density, low cost and environmental friendliness. However, developing high-energy-density Li–S batteries is seriously hindered by their short cycling life, originating from the shuttle effect of soluble polysulfides. Herein we for the first time develop a versatile and facile strategy of assembling thin and lightweight bi-functionalized hybrid interlayer constructed by two-dimensional (2D) electrochemically exfoliated graphene and Co(OH)2 nanosheets (EG/Co(OH)2), positioned between the cathode and commercial polypropylene (PP) separator, for high-performance Li–S batteries with remarkably enhanced capacity, rate capability and long-term cyclability. The resulting 2D EG/Co(OH)2 hybrid interlayer features layer-stacked structure, thin thickness of 5.5 μm, high electrical conductivity of 900 S cm−1, low mass loading of 0.20 mg cm−2, and exhibits bi-functionalized roles of polysulfide physical barrier from EG nanosheets and high chemical adsorption for polysulfides by Co(OH)2 nanosheets. As a result, the assembled Li–S batteries based on graphene-S cathode, using EG/Co(OH)2 interlayer, showed greatly enhanced discharge capacity of 918 mAh g−1 at 0.5 C, in comparison with the cells (831 mAh g−1) free of EG/Co(OH)2 interlayer. Furthermore, our Li–S batteries with EG/Co(OH)2 interlayer displayed outstanding rate capacity of 677 mAh g−1 at 5 C, and exceptional cycling stability with a high capacity of 565 mAh g−1 after 300 cycles at 0.5 C, corresponding to ultralow capacity fade rate of only 0.130% per cycle. Therefore, our strategy of constructing a hybrid interlayer consisting of 2D different nanosheets will offer numerous opportunities for designing long-life and high-energy-density Li–S batteries.
Photoelectrochemical Response of WO3/Nanoporous Carbon Anodes for Photocatalytic Water Oxidation

This work demonstrates the ability of nanoporous carbons to boost the photoelectrochemical activity of hexagonal and monoclinic WO3 towards water oxidation under irradiation. The impact of the carbonaceous phase was strongly dependent on the crystalline structure and morphology of the semiconductor, substantially increasing the activity of WO3 rods with hexagonal phase. The incorporation of increasing amounts of a nanoporous carbon of low functionalization to the WO3 electrodes improved the quantum yield of the reaction and also affected the dynamics of the charge transport, creating a percolation path for the majority carriers. The nanoporous carbon promotes the delocalization of the charge carriers through the graphitic layers. We discuss the incorporation of nanoporous carbons as an interesting strategy for improving the photoelectrochemical performance of nanostructured semiconductor photoelectrodes featuring hindered carrier transport.
TIUI: Touching Live Video for Telepresence Operation

This paper presents a framework for telepresence operation by touching live video on a touchscreen. Our goal is to enable users to use a smartpad to teleoperate everyday objects by touching the objects’ live video they are watching. To this end, we coined the term “teleinteractive device” to describe such an object with an identity, an actuator, and a communication network. We developed a touchable live video image-based user interface (TIUI) that empowers users to teleoperate any teleinteractive device by touching its live video with touchscreen gestures. The TIUI contains four modules — touch, control, recognition, and knowledge — to perform live video understanding, communication, and control for telepresence operation. We implemented a telepresence operation system that consists of a telepresence robot and teleinteractive devices at a local site, a smartpad with the TIUI at a remote site, and communication networks connecting the two sites. We demonstrated potential applications of the system in remotely controlling telepresence robots, opening doors with access control panels, and pushing power wheelchairs. We conducted user studies to show the effectiveness of the proposed framework.
Structural Investigation into Magnetic Spin Orders of a Manganese Phosphatic Oxyhydroxide, Mn5[(PO4)2(PO3(OH))2](HOH)4

The ferri- and antiferromagnetic structures of a hureaulite-type synthetic compound, Mn2+5(PO4)2(PO3(OH))2(HOH)4, were elucidated by high-resolution neutron powder diffraction in combination with magnetic susceptibility and heat capacity measurements. At 6.17 K, the paramagnetic phase (space group: C2/c) transforms to inherit a ferrimagnetic order (magnetic space group: C2′/c′), followed at 1.86 K by an incommensurately modulated antiferromagnetic order (magnetic superspace group: P21/c.1′(α0γ)00s with the propagation vector k(0.523(2), 0, 0.055(1)). In the ferrimagnetic state, antiferromagnetic interactions are dominant for both intra and inter pentamers of Mn2+(O, HOH)6 octahedra. Differently aligned spin-canting sublattices seen in the ferrimagnetic models at 3.4, 4.5, and 6.1 K explain a weak ferromagnetism in the title compound. The observation of magnetic moments vigorously changing in a small temperature range of 6.1–1.5 K adumbrates a high complexity of interplaying structural and magnetic orders in this manganese phosphatic oxyhydroxide.
Structure of solid chlorine at 1.45 GPa

Abstract Single crystals of solid chlorine (Cl2) were synthesized at room temperature and high pressure (HP, P=1.45 GPa) in a diamond anvil cell (DAC). At these conditions Cl2 adapts the same structure as its corresponding low-temperature (LT) ambient pressure modification (T<172 K), as concluded from HP single crystal diffraction experiments. Namely, it crystallizes in an orthorhombic symmetry (Cmce spacegroup) with Cl2 molecules forming monolayers parallel to the bc plane and this structure is preserved up to at least 64 GPa. The pressure of 1.45 GPa is to be considered as a solidification point of liquid Cl2 at room temperature.

Polycrystalline Ca0.925Ce0. 075Mn0.9Fe0. 1O3 were prepared by sol-gel reaction at 1073 K. The compound was analyzed by a powder X-ray diffraction technique and found to be in single phase. The unit-cell parameters and atomic positions were refined using General Structure Analysis to an orthorhombic structure with space group Pnma (#62) a = 5.281 90 (33) Å, b = 7.4968 (45) Å, and c = 5.302 90 (32) Å.
Determination of Voriconazole in Human Plasma Using RP-HPLC/UV-VIS Detection: Method Development and Validation; Subsequently Evaluation of Voriconazole Pharmacokinetic Profile in Pakistani Healthy Male Volunteers

In this research work, an isocratic, reversed-phase high-performance liquid chromatography-ultraviolet/visible detector method was developed for analysis of voriconazole standard (stock-solution) and in plasma samples. Optimization and validation of the method was carried out as per international guidelines. The method offered a simple liquid–liquid extraction technique, which exhibited best recovery of voriconazole along with fluconazole, i.e., internal standard. Different experimental conditions were tried and ultimately, the best outcomes were accomplished utilizing C-18 Perkin-Elmer® column with particulars of 150 mm length, 4.6 mm inner diameter and 5 μm particle size, protected by an RP-18 Perkin-Elmer® Pre-column guard cartridge with specifications of 10 μm particle size, 30 mm length and 4.6 mm inner diameter, utilizing mobile-phase of acetonitrile-water (ACN: H2O) in proportion of 60: 40 v/v, having a flow rate of 1.5 mL/min, and wavelength of 254 nm. All the analytes were observed to be separated in ≤7 min. A linear calibration curve was obtained at concentration range of 01–10 μg/mL of voriconazole. The correlation coefficient of voriconazole was observed to be 0.999, and average recovery (in percent) was 97.4%, whereas the relative standard deviation value was ≤2%. The lower limit of detection was 0.01 μg/mL, whereas, lower limit of quantification was 0.03 μg/mL, respectively. This developed method provided outstanding results of all validation parameters, i.e., recovery, accuracy, selectivity, precision and reproducibility. The method proposed for voriconazole analysis was applied effectively for further research investigation of voriconazole in human-plasma samples (to assess the pharmacokinetic parameters), pharmaceutical formulations and pharmacokinetic drug–drug interaction’s.

Development of an online-coupled MARGA upgrade for the 2 h interval quantification of low-molecular-weight organic acids in the gas and particle phases

Abstract. A method is presented to quantify the low-molecular-weight organic acids such as formic, acetic, propionic, butyric, pyruvic, glycolic, oxalic, malonic, succinic, malic, glutaric, and methanesulfonic acid in the atmospheric gas and particle phases, based on a combination of the Monitor for AeRosols and Gases in ambient Air (MARGA) and an additional ion chromatography (Compact IC) instrument. Therefore, every second hourly integrated MARGA gas and particle samples were collected and analyzed by the Compact IC, resulting in 12 values per day for each phase. A proper separation of the organic target acids was initially tackled by a laboratory IC optimization study, testing different separation columns, eluent compositions and eluent flow rates for both isocratic and gradient elution. Satisfactory resolution of all compounds was achieved using a gradient system with two coupled anion-exchange separation columns. Online pre-concentration with an enrichment factor of approximately 400 was achieved by solid-phase extraction consisting of a methacrylate-polymer-based sorbent with quaternary ammonium groups. The limits of detection of the method range between 0.5 ng m−3 for malonate and 17.4 ng m−3 for glutarate. Precisions are below 1.0 %, except for glycolate (2.9 %) and succinate (1.0 %). Comparisons of inorganic anions measured at the TROPOS research site in Melpitz, Germany, by the original MARGA and the additional Compact IC are in agreement with each other (R2 = 0.95–0.99). Organic acid concentrations from May 2017 as an example period are presented. Monocarboxylic acids were dominant in the gas phase with mean concentrations of 306 ng m−3 for acetic acid, followed by formic (199 ng m−3), propionic (83 ng m−3), pyruvic (76 ng m−3), butyric (34 ng m−3) and glycolic acid (32 ng m−3). Particulate glycolate, oxalate and methanesulfonate were quantified with mean concentrations of 26, 31 and 30 ng m−3, respectively. Elevated concentrations of gas-phase formic acid and particulate oxalate in the late afternoon indicate photochemical formation as a source.
Inhibition of cardiomyocyte apoptosis post-acute myocardial infarction through the efficient delivery of microRNA-24 by silica nanoparticles

MicroRNA-24 (miR-24) is an apoptosis suppressor miRNA downregulated in cardiomyocytes after acute myocardial infarction (AMI). However, due to the lack of effective delivery strategies, the role of anti-apoptotic miR-24 in cardiomyocytes post-acute myocardial infarction remains unexplored. Here, we used a silica nanoparticle-based polyelectrolyte (polyethylenimine, PEI) delivery system to study the role of miR-24. These particles with good biocompatibility could be efficiently internalized into cells and release the loaded miR-24 into the cytoplasm. As a result, the overexpression of miR-24 resulted in the inhibition of the pro-apoptotic Bim, thereby inhibiting cardiomyocyte apoptosis in vitro. Furthermore, in vivo experiments revealed that over-expressed miR-24 additionally significantly improves ventricular remodeling and cardiac function in Sprague–Dawley (SD) rats after coronary artery ligation. In summary, our novel delivery system serves as a therapeutic miRNA formulation for cardiovascular disease treatment.
Emotion-Involved Semantic Processing and L2 Vocabulary Memory: A Micro-Level Emotion Manifesto

Emotion is a pervasive phenomenon whose pivotal impacts on cognition have been proposed and increasingly acknowledged (e.g., operator effect and “(de-)energizing” effect; cf. Ciompi & Panksepp, 2005; Damasio, 2003; LeDoux, 2012). In accordance with this, second language acquisition (SLA) studies have recently seen an “affective turn” (Pavlenko, 2013) and several theories have been proposed and studies conducted concerning the effect of affect in SLA from such perspectives as motivation (Dörnyei & Ushioda, 2011), foreign language anxiety/enjoyment (Dewaele & MacIntyre, 2016), Directed Motivational Currents (Dörnyei, Henry, & Muir, 2016), and emotional intelligence (Gregersen & MacIntyre, 2017; Kanazawa, 2016b). The purpose of the experiments was to examine whether emotion-involved semantic processing (EmInvSemProc) results in better incidental L2 memory performance compared to other types of semantic processing (viz., a lexical decision task [LDT] for Experiment A and an imageability judgment task [IJT] for Experiment B).
Simultaneous Pulsating Aurora and Microburst Observations With Ground‐Based Fast Auroral Imagers and CubeSat FIREBIRD‐II

We report on the relationship between a pulsating aurora and a relativistic electron microburst using simultaneous observations of ground‐based fast auroral imagers with the FIREBIRD‐Ⅱ CubeSat for the first time. We conducted a detailed analysis of an event on October 8, 2018 and found that the occurrence of the pulsating aurora with internal modulations corresponds to the flux enhancement of electrons with energy ranging from ∼220 keV to >1 MeV detected with Flight Unit 4, one of FIREBIRD's CubeSat, with a time delay of ∼585 ms. Combining of this time delay result and time of flight model, we suggest that the pulsating aurora and the microburst occur simultaneously due to the chorus waves at different latitudes along the same field‐line as predicted by Miyoshi et al. (2020, https://doi.org/10.1029/2020gl090360).
