MicroRNA-1 (miR-1) is a conserved microRNA that is highly expressed in skeletal and cardiac muscle tissues. Moreover, miR-1 regulates genes and has critical roles in cell migration and invasion. Downregulation of miR-1 has been found in many pathologies of numerous organs, including the lungs. What exactly contributes to the downregulation of miR-1 is not fully understood, and in the present study, we investigated whether ROS regulate miR-1 and its role in cell migration and invasion. A549 cells were grown and maintained in DMEM:F12 (1:1) and supplemented with 10% FBS and 1000 U of Penicillin/Streptomycin and maintained as recommended by the manufacturer (ATCC). Cell migration and invasion, IHC, Western blot, qPCR, ROS, miR-1 transfection, and qPCR were used to determine miR-1 regulation and its role in cell migration. Exogenous miR-1 decreased the formation of ROS and inhibited cell migration and invasion, whereas inhibition of miR-1 increased ROS formation and stimulated cell migration and invasion. Inhibition of miR-1 induced the formation of actin filaments contractile structures, whereas exogenous miR-1 limited the formation of these structures. Hydrogen peroxide significantly decreased miR-1 level, whereas inhibition of Nox4 had no effect on miR-1 level. Alpha amanitin did not decrease miR-1 level, whereas inhibition of NF-кB temporally decreased miR-1 level. This study demonstrates that ROS suppress miR-1 and that miR-1 is posttranscriptionally regulated via MAPK. Endogenous Nox4-dependent ROS are not involved in miR-1 regulation, whereas exogenous ROS regulates miR-1. NF-κB plays a key role in miR-1 regulation in both redox and nonredox environments. Moreover, Mir-1 limits cell migration and invasion even in the presence of ROS. TSP-1 is a major regulator of TGFβ and its expression is upregulated by ROS. Our work indicates ROS is a major regulator of miR-1 and TSP-1 and could be a potential therapeutic target to limit ROS- and non-ROS-mediated processes in l

This study aims to understand the willingness of urban communities in Jabodetabek (Jakarta, Bogor, Depok, Tangerang, Bekasi) to move to apartment dwellings, and a study was conducted using a quantitative survey method. The study aimed to analyze the sociodemographic factors influencing the decision to switch to vertical housing. The survey collected data from a sample of individuals representing the entire population in Jabodetabek. The participants in the study were selected from various locations within Jabodetabek, including Jakarta, Bogor, Depok, Tangerang, and Bekasi. These areas were chosen to comprehensively represent the metropolitan region and its urban communities. By including participants from different locations within Jabodetabek, the study aimed to capture individuals' diverse perspectives and experiences in this region. The survey covered a range of sociodemographic factors such as gender, income, education level, marital status, occupancy, and residence ownership. The participants were divided into two groups: those willing to pay for an apartment and those who wereilling to pay for an apartment and those not. By comparing the characteristics of these two groups, the study aimed to identify significant differences and understand the factors influencing the willingness to move to apartment dwellings. The study results showed significant differences in income level, education level, marital status, and occupancy between the two groups. Income level was the most significant factor affecting an individual's willingness to pay for an apartment. Additionally, the perception of better apartment productivity, which includes reduced transportation time and costs associated with work or other business purposes, increased the demand for apartments. The study found that income level was the most significant factor affecting an individual's willingness to pay for an apartment. The perception of better apartment productivity also increased demand for apartments,

Chemical additives to perovskite precursors constitute a predominant route to passivate defects in perovskite films and improve carrier charge dynamics. In this work, ionic liquids (ILs) with chloride and iodide anions are used as additives for bulk passivation of perovskite films. The ionic liquids in the form of 1‑butyl‑4-methylpyradinium iodide (IL-I) and 1-ethylimidazolium chloride (IL-Cl) are mixed individually with a precursor of Cesium Formamidinium Lead Triiodide and Methylammonium Chloride (CsFAPbI3−MACl). The decay of charge carriers within the perovskite film before and after passivation with ILs was measured by Time Resolved Photoluminescence Spectroscopy (TRPL). The effect of added ILs on the recombination rate of the photocarriers was investigated by analyzing the decay of the TRPL signal in all samples. The average lifetimes obtained within one day of preparations were 79 ns, 73 ns and 275 ns for pristine perovskite, IL-I passivated perovskite and IL-Cl passivated perovskite films, respectively. These values show that the presence of the IL with chloride anion greatly improves the average lifetime of the charge carrier by around 250%, while IL with iodide anion decreased the lifetime by 32% as compared with the pristine perovskite sample. This finding renders the IL-Cl passivated perovskite films as a valuable resource in applications ranging from photoelectric to hydrogen generation devices. © 2023

Implantable biomedical devices (IBDs) have garnered wide-scale attention in recent years due to their enormous contribution to the biomedical sector. However, an uninterrupted and reliable power source has consistently been the primary barrier for IBDs, which is greatly alleviated by batteries. The widespread application of battery-powered IBDs is hindered by several limitations, including bulkiness, limited capacity and shelf-life, and expenditure associated with surgery-based battery recharge/replacement. To address these challenges, state-of-the-art self-powering technologies have emerged, including implantable piezoelectric nanogenerators (iPENGs) and implantable triboelectric nanogenerators (iTENGs). These technologies enable IBDs to operate autonomously by harnessing the minute mechanical movements of internal organs, such as heartbeat, respiration, blood circulation, muscle contraction/relaxation, and lung vibration. This review focuses on the recent advancements in iTENGs and iPENGs for the development of self-powered IBDs with a wide range of applications, including energy harvesting from biomechanical and ultrasound sources and energy storage using batteries and capacitors. This study also explores the extensive sensing applications of IBDs in various areas including cardiac, gastrointestinal, bladder, and ligament-strain monitoring. Finally, therapeutic applications of IBDs, such as nerve stimulation, bone stimulation, cartilage therapy, tissue regeneration, muscle stimulation, drug delivery, and diabetes management are discussed. © 2023 Elsevier Ltd

In 2017 summer, we observed a widespread bottom hypoxic zone at the lower estuary of the Pearl River estuary (PRE). We observed i) bacterial and AOA biomass accumulation, ii) oxygen consumption rates (respiration and nitrification) in the hypoxic zone. The potential microbial interaction of both oxygen-consuming microbes in the hypoxia remained unclear. To investigate the potential microbial interaction between AOA and heterotrophic bacteria in the hypoxic zone, we used bacterial and AOA communities (inferred from 16S rRNA gene and amoA gene, respectively) and multi-comparisons between the co-occurrence networks retrieved from DNA and RNA levels to reflect the pattern. We observed a highly diverse and active bacterial community in the hypoxia zone. The network topology revealed that Gammaproteobacteria, Bacteroidetes (Flavobacteriales), Alphaproteobacteria (Rhodobacterales and Rhodospirillales), Marinimicrobia, Cyanobacteria (Synechococcales), and AOA sublineages were module hubs and connectors, indicating that they were the keystone taxa of the microbial communities. The hub-subnetwork further showed robust co-occurrence between Gammaproteobacteria, Bacteroidetes (Flavobacteriales), Alphaproteobacteria (Rhodobacterales and Rhodospirillales), Marinimicrobia with AOA sublineages, and Nitrospinae (presumably NOB)) reflecting the formation of Degradation-Nitrification microbial assemblage in the hypoxia zone. The subnetworks revealed AOA ecotype-specific modularization and niche partitioning of different AOA sublineages. Interestingly, the recurring co-occurrence of SCM1-like II sublineages with Nitrospinae OTUs formed nitrifiers assemblage in the RNA subnetworks suggested an interaction via nitrite exchange. The Degradation-Nitrification microbial assemblage may contribute substantially to the oxygen consumption in the hypoxia formation in PRE. Our results provide new insight into the nitrifier-associated microbial assemblage that should be further explored in the mar

Global ground-level measurements of elements in ambient particulate matter (PM) can provide valuable information to understand the distribution of dust and trace elements, assess health impacts, and investigate emission sources. We use X-ray fluorescence spectroscopy to characterize the elemental composition of PM samples collected from 27 globally distributed sites in the Surface PARTiculate mAtter Network (SPARTAN) over 2019-2023. Consistent protocols are applied to collect all samples and analyze them at one central laboratory, which facilitates comparison across different sites. Multiple quality assurance measures are performed, including applying reference materials that resemble typical PM samples, acceptance testing, and routine quality control. Method detection limits and uncertainties are estimated. Concentrations of dust and trace element oxides (TEO) are determined from the elemental dataset. In addition to sites in arid regions, a moderately high mean dust concentration (6 μg/m) in PM is also found in Dhaka (Bangladesh) along with a high average TEO level (6 μg/m). High carcinogenic risk (>1 cancer case per 100000 adults) from airborne arsenic is observed in Dhaka (Bangladesh), Kanpur (India), and Hanoi (Vietnam). Industries of informal lead-acid battery and e-waste recycling as well as coal-fired brick kilns likely contribute to the elevated trace element concentrations found in Dhaka.

ABSTRACTABSTRACTAll-terrain vehicle (ATV) crashes are one of the leading causes of death and injury in agriculture across the United States. Use of ATVs is highly prevalent in rural areas and has seen an increase in their application for a variety of agricultural work tasks. Empirical research on the use of these vehicles for agricultural tasks and associated injuries is limited, especially in the United States. Moreover, little is known about the risk factors associated with ATV-related injuries while doing farm work. A comprehensive review was conducted to evaluate the current injury burden of ATV use in agriculture, the need for future research, and possible solutions related to agricultural ATV safety. Potential injury prevention approaches are evaluated based on the hierarchy of control, including elimination or substitution (using side-by-side vehicles instead of ATVs or modifying ATV design), engineering control (operator protection devices), administrative authority (regulations and standards in the United States and around the world), training, and use of personal protective equipment. In addition, vehicle nomenclature, risk factors, and crash mechanisms are reviewed. Recommendations to decrease the likelihood of ATV crashes and injuries are provided.

The unique physico-chemical, electronic, redox, and UV-absorption properties of the engineered nano-particles (ENPs) make them suitable for many industrial applications including consumer goods. Agriculture is a major area where nanotechnologies are applied. Therefore, soil/sediment becomes an important environmental sink for ENP waste disposal. Hence, the fate and transport of ENPs in soil is of particular interest to the scientific community. This short review summarizes the recent findings of studies dealing with the related fundamental concepts. It touches upon the physico-chemical properties of soil and those of ENPs, the soil and solution chemistries, the environmental factors, and the influence of other chemical moieties as possible factors affecting the fate of ENPs in soil. © 2018 Elsevier B.V.

Background: Decades of steady improvements in life expectancy in Europe slowed down from around 2011, well before the COVID-19 pandemic, for reasons which remain disputed. We aimed to assess how changes in risk factors and cause-specific death rates in different European countries related to changes in life expectancy in those countries before and during the COVID-19 pandemic. Methods: We used data and methods from the Global Burden of Diseases, Injuries, and Risk Factors Study 2021 to compare changes in life expectancy at birth, causes of death, and population exposure to risk factors in 16 European Economic Area countries (Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, the Netherlands, Norway, Portugal, Spain, and Sweden) and the four UK nations (England, Northern Ireland, Scotland, and Wales) for three time periods: 1990–2011, 2011–19, and 2019–21. Changes in life expectancy and causes of death were estimated with an established life expectancy cause-specific decomposition method, and compared with summary exposure values of risk factors for the major causes of death influencing life expectancy. Findings: All countries showed mean annual improvements in life expectancy in both 1990–2011 (overall mean 0·23 years [95% uncertainty interval [UI] 0·23 to 0·24]) and 2011–19 (overall mean 0·15 years [0·13 to 0·16]). The rate of improvement was lower in 2011–19 than in 1990–2011 in all countries except for Norway, where the mean annual increase in life expectancy rose from 0·21 years (95% UI 0·20 to 0·22) in 1990–2011 to 0·23 years (0·21 to 0·26) in 2011–19 (difference of 0·03 years). In other countries, the difference in mean annual improvement between these periods ranged from –0·01 years in Iceland (0·19 years [95% UI 0·16 to 0·21] vs 0·18 years [0·09 to 0·26]), to –0·18 years in England (0·25 years [0·24 to 0·25] vs 0·07 years [0·06 to 0·08]).

Engineered Nanomaterials (ENMs) are revolutionizing our daily lives, industry, and agriculture. Along with their novel applications, major concerns have emerged due to the potential toxicity to biological systems. Since soils are considered the main destination for ENMs, research focused on their interaction with plants is gaining more attention, especially at the physiological and biochemical levels. This review addresses the capacity of some plants to accumulate ENMs or released ions, highlighting the beneficial and detrimental effects and the potential use of some plants to remediate ENM-contaminated environments. Although the uptake process depends on multiple factors, the literature suggests that concentrations <50 mg/kg are beneficial, while higher doses negatively impact physiological and biochemical parameters. However, the current data does not allow the formulation of mechanistic model effects. Finally, this review remarks on the pivotal role played by plants as a sustainable alternative to face the environmental buildup of ENMs and to guarantee food security. © 2018 Elsevier B.V.
