Article Simultaneous selective removal of cesium and cobalt from water using calcium alginate-zinc ferrocyanide-Cyanex 272 composite beads Composite beads consisting of Ca alginate mixed with zinc ferrocyanide (ZnFC) and Cyanex 272 were synthesized in order to selectively adsorb Cs+ and Co2+ from water. Their physicochemical properties of the synthesized composite beads were characterized using various techniques, including FESEM, EDX, FTIR, and TGA. The ZnFC/Cyanex 272/alginate (ZCA) composite beads were then tested as an adsorbent for the selective removal of Cs+ and Co2+ from an aqueous solution. The adsorption capacity increased with increasing ZnFC and Cyanex 272 contents. The adsorption process followed the Langmuir model and pseudo-second-order kinetics. The ZCA composite beads exhibited excellent selectivity toward Cs+ and Co2+ even in the presence of competitive cations (K+, Na+, Fe2+, and Ni2+). The adsorption capacity of the ZCA composite beads for Cs+ and Co2+ was almost maintained after three times of adsorption-desorption process.

Article Synergistic interaction of fungal endophytes, Paecilomyces formosus LHL10 and Penicillium funiculosum LHL06, in alleviating multi-metal toxicity stress in Glycine max L. Heavy metal accumulation in crop grains due to hazardous metal contamination is considered a great concern. However, phytobeneficial fungi are reported to have important abilities for the biosafety of crops grown in contaminated soil. Therefore, the current study was undertaken to explore the mutualistic association of plant growth-promoting endophytic fungi in reducing heavy metal concentration in the seeds of soybean plants subsequently grown in contaminated soil, without comprising seed quality and biochemical profile. The results revealed that endophytic Paecilomyces formosus LHL10 and Penicillium funiculosum LHL06 synergistically produced higher amounts of GAs and IAA in a co-cultured medium. Moreover, the co-inoculation of LHL06 and LHL10 to soybean plants grown under multi-metal toxic conditions significantly mitigated the adverse effects of heavy metal toxicity and increased the seed production (number of pods per plants, number of seeds per pod, and 100 seed weight) of soybean plants grown under control and multi-metal toxic conditions. Moreover, the levels of carbohydrates (glucose, sucrose, and fructose), minerals (iron, calcium, magnesium, and potassium), amino acids (serine, glutamic acids, glycine, methionine, lysine, arginine, and proline), and antioxidants (superoxide dismutase, catalase, and peroxidase) were significantly enhanced in sole and co-inoculated plants under control and stress conditions. Whereas organic acids (citric acid, tartaric acid, malic acid, and succinic acid), lipid peroxidation (MDA) products, multi-metal accumulation (nickel, cadmium, copper, lead, chromium, and aluminum), and stress-responsive endogenous abscisic acid levels were significantly decreased in seeds of soybean plants grown under control and multi-metal toxic conditions upon LHL06 and LHL10 sole and co-inoculation. The current results suggested the positive biochemical regulation in seeds for improving the nutritional status and making it safe for human consumption.

Article The Recovery of Metallic Tin from an Industrial Tin-Bearing By-Product Containing Na2SO4 by Reduction Smelting Process Tin was recovered in metal from an industrial tin-bearing byproduct containing Na2SO4 by carbothermic reduction smelting, and the effects of basicity (Na2O/SiO2), temperature, and reaction time on the recovery of tin were studied. Na2SO4 was reduced by carbon and formed into sodium silicate slag (Na2O-SiO2) in the presence of SiO2. Tin content in slag decreased with the increase of Na2O/SiO2 ratio in slag, temperature, and reaction time, but the recovery of tin was affected by volatilization of tin in high temperature and high silica region of basicity. In this study, the maximum recovery rate of tin was 94.8% at the experimental condition of 1200 & DEG;C, 2 h, and 0.55 of Na2O/SiO2 ratio. The major impurities in produced metal were Bi, Pb, Cu, Fe, and most of Bi, Pb, Cu were distributed to the metal phase, but the distribution of Fe was closely related to basicity.

Review Uncertainty of pesticides in foodstuffs, associated environmental and health risks to humans-a critical case of Bangladesh with respect to global food policy The uncertain fate and transport pathways of applied pesticides are the key hidden threats with respect to the safety and quality evaluation of foodstuffs in Bangladesh. The risk assessment of and uncertainty about applied pesticides are poorly explored due to weak regulatory systems, farmer ignorance, intensive agricultural practices, and lack of available research data on improper handling of pesticides on farming lands with poor phytosanitary management. However, increasing evidence suggests that the prevalence of pesticides in common foodstuffs is due to their uptake by crops and improper management of crop protection practices. Besides, the biotransformation of pesticides in common Bangladeshi food products is poorly understood. Several studies have reported higher concentrations of pesticides than allowed by European Union guidelines in Bangladeshi foodstuffs. However, to date, no systematic review with critical discussion on current research findings and knowledge gaps concerning fate, uncertainty, and health risks of pesticides in the foodstuffs of Bangladesh is published. Therefore, this review summarizes the findings of existing literature on pesticide residue in foodstuffs and points out the weaknesses in the regulatory system and risk assessments for highlighting the critical challenges to food safety in Bangladesh as compared to global food policy. In addition, strategies for the sustainable management of residual pesticides are also discussed.

Article Application of Laser-Desorption Silver-Ionization Ultrahigh-Resolution Mass Spectrometry for Analysis of Petroleum Samples Subjected to Hydrotreating In this study, silver ion (Ag+)-aided laser-desorption ionization coupled to Fourier transform ion cyclotron resonance mass spectrometry was applied to investigate the effects on sulfur-containing compounds after the hydrodesulphurization (HDS) process. For this purpose, three sets of atmospheric residue (AR) and treated atmospheric residue (tAR) samples were analyzed by adding silver nitrate (AgNO3) solution at an optimized concentration ratio of 1:1. Two high-sulfur samples (5.51 and 4.68% each) and one low-sulfur (0.47%) AR sample were studied. The results presented in this study showed that significant changes in the sulfur (S-1 and S-2) and hydrocarbon (HC) class were observed after treatment of the high-sulfur AR samples. The removal of S1 species with lower double-bond equivalent values (DBE) (DBE 9) values. In addition, the abundance of the aromatic HC class was significantly increased, but the abundance of the nonaromatic HC class was not. In the case of a low-sulfur AR sample, no significant change in HC class was observed after treatment. Therefore, it was concluded that the transformation of benzo- and dibenzothiophene-type compounds to aromatic HCs is the major reaction occurring in the HDS process. The reaction pathways for the transformation were suggested based on the results obtained in this study and previous literature. This study confirms that laser-desorption silver ionization can efficiently ionize the hydrocarbons and nonpolar sulfur-containing compounds present in crude oil.

Article Characterization and Structural Classification of Heteroatom Components of Vacuum-Residue-Derived Asphaltenes Using APPI (+) FT-ICR Mass Spectrometry Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) has been widely used as a major breakthrough to investigate the structure of asphaltenes in heavy oils. In this study, saturates, aromatics, resins, and asphaltenes (SARA) fractions derived from vacuum residue were analyzed using FT-ICR MS, and, particularly, the asphaltenes were examined in detail. Basically, the mass-to-charge ratio spectra, double bond equivalents (DBE) distribution, and heteroatom classes of SARA fractions were checked. After that, we delved into the asphaltenes with very high aromaticity and classified the asphaltenes according to heteroatom classes to understand their structural diversity. This classification disclosed that the DBE distribution of asphaltenes exhibited different trends, depending on heteroatom classes and the number of heteroatoms, which could not be identified by DBE distribution of whole asphaltenes. Based on the relative abundance peaks of the DBE and carbon number distribution, the compositional space of DBE and carbon number was separated into four groups in various heteroatom classes. The structure types of asphaltenes corresponding to each group are maltene-like components (DBE 5-15, carbon number 20-60), archipelago-type asphaltenes (DBE 10-25, carbon number 25-70), island-type asphaltenes (DBE 15-35, carbon number 25-60), and larger island-type asphaltenes (DBE 35-50, carbon number 40-75), which are highly aromatic and independent of the normal island-type asphaltenes. The classification results are expected to be applied to develop a structural model of asphaltenes.

Article Is Culture Expansion Necessary in Autologous Mesenchymal Stromal Cell Therapy to Obtain Superior Results in the Management of Knee Osteoarthritis?-Meta-Analysis of Randomized Controlled Trials Study Design: Meta-analysis. Objectives: We aimed to analyze the impact of cultured expansion of autologous mesenchymal stromal cells (MSCs) in the management of osteoarthritis of the knee from randomized controlled trials (RCTs) available in the literature. Materials and Methods: We conducted independent and duplicate electronic database searches including PubMed, Embase, Web of Science, and Cochrane Library until August 2021 for RCTs analyzing the efficacy and safety of culture-expanded compared to non-cultured autologous MSCs in the management of knee osteoarthritis. The Visual Analog Score (VAS) for pain, Western Ontario McMaster University's Osteoarthritis Index (WOMAC), Lysholm score, Knee Osteoarthritis Outcome Score (KOOS), and adverse events were the analyzed outcomes. Analysis was performed in R-platform using OpenMeta [Analyst] software. Results: Overall, 17 studies involving 767 patients were included for analysis. None of the studies made a direct comparison of the culture expanded and non-cultured MSCs, hence we pooled the results of all the included studies of non-cultured and cultured types of MSC sources and made a comparative analysis of the outcomes. At six months, culture expanded MSCs showed significantly better improvement (p < 0.001) in VAS outcome. Uncultured MSCs, on the other hand, demonstrated significant VAS improvement in the long term (12 months) in VAS (p < 0.001), WOMAC (p = 0.025), KOOS score (p = 0.016) where cultured-expanded MSCs failed to demonstrate a significant change. Culturing of MSCs did not significantly increase the complications noted (p = 0.485). On sub-group analysis, adipose-derived uncultured MSCs outperformed culture-expanded MSCs at both short term (six months) and long term (12 months) in functional outcome parameters such as WOMAC (p < 0.001, p = 0.025), Lysholm (p < 0.006), and KOOS (p < 0.003) scores, respectively, compared to their controls. Conclusions: We identified a void in literature evaluating the impact of culture expansion of MSCs for use in knee osteoarthritis. Our indirect analysis of literature showed that culture expansion of autologous MSCs is not a necessary factor to obtain superior results in the management of knee osteoarthritis. Moreover, while using uncultured autologous MSCs, we recommend MSCs of adipose origin to obtain superior functional outcomes. However, we urge future trials of sufficient quality to validate our findings to arrive at a consensus on the need for culture expansion of MSCs for use in cellular therapy of knee osteoarthritis.

Article Molecular Behaviors on Asphaltenes during Atmospheric Residue Hydrodesulfurization A two-stage hydrotreatment of the two atmospheric residues (LF-AR and KEC-AR) over the MoO3/gamma-alumina catalyst at the first stage and the NiMo/gamma-alumina catalyst at the second stage was performed. Evolution of various heteroatom classes in the asphaltenes during the hydrotreating process was examined, focusing on removing sulfur and nitrogen species from asphaltenes. Various heteroatom classes (CcHh, CcHh-S-s, CcHh-N-n, CcHh-O-o, CcHh-NnSs, CcHh-OoSs, CcHh-NnOo, and CcHh-NnOoSs) in the asphaltenes were analyzed by using Fourier transfer ion cyclotron mass spectrometry (FT-ICR MS) linked with atmospheric pressure photoionization (APPI). According to the changes of their relative abundance, double bond equivalent (DBE), and the carbon number in the hydrotreating process, behaviors of the various heteroatom classes in the asphaltenes during the hydrotreating process were interpreted. Two distinctive differences in heteroatom reduction were observed for two different AR samples, and qualitative evaluation was attempted for providing possible scenarios.

Article Molecular-Level Structural Analysis of Hydrotreated and Untreated Atmospheric Residue Oils via Atmospheric Pressure Photoionization Cyclic Ion Mobility Mass Spectrometry and Ultrahigh-Resolution Mass Spectrometry Changes in the structure of oil compounds subjected to hydrodesulfurization were investigated using ultrahigh-resolution mass spectrometry (UHR-MS) and cyclic ion mobility mass spectrometry (cIM-MS) techniques. The isolation of ions with a separation of less than 0.1 Da followed by collision-induced dissociation helped clarify the structure. The class and double bond equivalence (DBE) distributions of the HC class observed by UHR-MS indicated that sulfur-containing compounds were transformed to HC compounds, in accordance with the previously reported mechanisms. The transformation was further observed by examining the tandem mass spectra of HC class compounds with the DBE values. The fragility of the molecules to collision-induced dissociation increased after hydrodesulfurization as a result of the increased abundance of naphthenic rings in the processed oils. The structural change was influenced by the DBE, and the most significant structural changes corresponded to HC compounds with DBE of 7. It was considered that compounds with naphthalene in the core structure were dominant in the untreated oils; however, the number of compounds with multiple naphthenic rings increased after the treatment. Moreover, the abundance of HC compounds with short alkyl chains likely increased. The results indicate that UHR-MS and cIM-MS are effective tools to clarify molecular-level changes in processed oils.

Article Tailoring the Composition of Ternary Layered Double Hydroxides for Supercapacitors and Electrocatalysis Layered double hydroxides (LDHs) have attracted great consideration in electrochemical systems such as super-capacitors and water splitting due to their layered structures, flexible interlayer distances, and tunable elemental compositions. Recently, ternary LDHs have been considered as efficient materials for energy-related applications due to their superior performance as compared to binary LDHs. To optimize the composition of ternary LDHs for electrochemical applications, herein, Co-, Ni-, and Fe-based ternary LDHs (CNFLs) at different molar ratios are prepared by a facile electrodeposition method. Among them, a sample with a higher concentration of Ni (Ni-rich CNFL) exhibits a maximal specific capacity of 467 C g(-1) at the sweep rate of 5 mV s(-1) with a capacity retention of 81% after 2000 cycles. In the case of electrocatalytic activity, the Ni-rich CNFL shows an appreciable overpotential of 139 mV to reach the current density of 10 mA cm(-2) along with the smallest Tafel slope (46 mV dec(-1)). The Ni-rich CNFL shows excellent electrocatalytic stability over 8 h of stable operation. This enhanced performance of Ni-rich CNFL is attributed to the synergic effect of Co, Ni, and Fe hydroxides and the anticipated growth of more Co-IV active sites with the higher surface area. Thus, CoNiFe LDH with a high concentration of Ni acts as a potential electrode material for electrochemical applications. Rohit, R.

Review Where Do We Stand in Stem Cell Therapy for the Management of Diabetes Mellitus?-A Scientometric Research Trend Analysis from 1990 to 2020 Stem cell therapy has been considered a promising strategy in the management of both type I and type II diabetes mellitus (DM) because of its immunomodulatory and regenerative capability to restore the beta cell number and function. Various modalities of cellular therapy like transplantation of pancreatic islet cells, transplantation of pancreatic ductal stem cells, and mesenchymal stromal cell transplantation have been tried, and the modality is undergoing rapid advancements that may become the reality in the near future. In the course of its evolution, it is essential to have a comprehensive summary of the progress for a greater capacity to refine our future directives. With technological developments like data mining, graphic drawing, and information analytics combined with computational statistics, visualization of scientific metrology has become a reality. With a newer perspective, we intend to use scientometric tools including text mining, co-word analysis, word frequency analysis, co-citation analysis, cluster network analysis, to perform a systematic and comprehensive analysis of the research trend in stem cell therapy in the management of DM over the past three decades (1990-2020) and to identify the future research hotspots.

Article Effect of dipeptidyl peptidase IV inhibitors, thiazolidinedione, and sulfonylurea on osteoporosis in patients with type 2 diabetes: population-based cohort study The population-based cohort study used the Korean National Health Insurance claims database to evaluate the effect of anti-diabetic drugs on osteoporosis. The use of DPP-IV inhibitors does not increase the risk of osteoporosis compared with the use of sulfonylureas in patients with type 2 diabetes mellitus, while a weak association was found between thiazolidinediones and increased risk of osteoporosis. Purpose The current study aimed to evaluate the effect of dipeptidyl peptidase IV inhibitors (DPP-IVi), thiazolidinedione (TZD), and sulfonylurea (SU) on osteoporosis in patients with type 2 diabetes. Methods A population-based cohort study was conducted in the Republic of Korea using the Korean National Health Insurance claims database. Data from 2012 to 2017 for patients of 50-99 years of age who were prescribed DPP-IVi, TZD, or SU during 2013-2015 were extracted from the database. Based on pre-defined criteria, a total of 381,404 patients were analyzed after inverse probability of treatment weighting. The association between the study drugs and osteoporosis was estimated using Cox proportional hazards models. Data of 220,166 patients who were prescribed DPP-IVi, 18,630 who were prescribed TZD, and 142,608 patients who were prescribed SU were set. Results In the multivariate-adjusted analysis, the hazard ratio (HR) of osteoporosis in the DPP-IVi group was not significantly different from that of the SU group (HR: 0.97; 95% confidence interval (CI) 0.94-1.00), whereas the HR of osteoporosis in the TZD group was higher (HR: 1.13; 95% CI 1.06-1.20). In the subgroup analysis, the HRs of osteoporosis were higher with pioglitazone (HR: 1.14; 95% CI 1.06-1.23) in the TZD group and with glibenclamides (HR: 1.39; 95% CI 1.09-1.77) in the SU group, whereas drugs with lower HR in the DPP-IVi group were saxagliptin (HR: 0.93; 95% CI 0.87-0.99) and sitagliptin (HR: 0.93; 95% CI 0.89-0.97). Conclusion DPP-IV inhibitors do not increase the risk of osteoporosis compared with sulfonylureas in patients with type 2 diabetes mellitus, while a weak association was found between thiazolidinediones and increased risk of osteoporosis.

Article High-quality 3D display system for an integral imaging microscope using a simplified direction-inversed computation based on user interaction We propose and implement a high-quality three-dimensional (3D) display system for an integral imaging microscope using a simplified direction-inversed computation method based on user interaction. A model of the specimen is generated fromthe estimated depth information (via the convolutional neural network-based algorithm), the quality of the model is defined by the high-resolution two-dimensional image. The new elemental image arrays are generated from the models via a simplified directioninversed computation method according to the user interaction and directly displayed on the display device. A high-quality 3D visualization of the specimen is reconstructed and displayed while the lens array is placed in front of the display device. The user interaction enables more viewpoints of the specimen to be reconstructed by the proposed system, within the basic viewing zone. Remarkable quality improvement is confirmed through quantitative evaluations of the experimental results.

Article Sonochemically synthesized nanostructured ternary electrode material for coin-cell-type supercapacitor applications Two-dimensional MoS2-based composite has remarkable potential as an electrode material for advanced energy storage. However, the potential application of MoS2 electrode is limited by its low electrical conductivity and cyclic stability. Herein, a novel three/two-dimensional (3D/2D) ternary nanostructured composite consisting of MoS2/g-C3N4/reduced graphene oxide (rGO), denoted as MCNG, is synthesized using an in-situ sonochemical-assisted method. Owing to the combined 3D/2D morphological features, large surface area, enriched interfacial conductivity, numerous surface-active edge sites, and mesoporous structure, the composite electrode exhibits a remarkable specific capacitance of 663 F g(-1) at current density of 0.5 A g(-1) and outstanding cyclic stability with a retention of 91.7% after 10,000 charge-discharge cycles. A coin-cell-type asymmetric supercapacitor composed of MCNG as the positive electrode and activated carbon (AC) as the negative electrode, presents an energy density of 11.43 Wh kg(-1) at a power density of 4125 W kg(-1). This synthesis scheme provides a new pathway for the development of multi-component 3D/2D sheet-like networks as efficient electrode materials and their applications in energy storage devices.
