ЭТИОЛОГИЯ СИНОНАЗАЛЬНОЙ ИНВЕРТИРОВАННОЙ ПАПИЛЛОМЫ: СОВРЕМЕННЫЙ ВЗГЛЯД НА ПРОБЛЕМУ

Abstract. Introduction. Inverted papilloma is the most common type of sinonasal papilloma. It refers to benign tumors, but its clinical course is often associated with post-surgical recurrences and malignancy. Although the morphological characteristics and clinical features of inverted papilloma are well known, its etiology and risk factors remain a matter of debate. Aim. The aim of the study was to analyze the contemporary literature and summarize the data available regarding the significance of viral infection, cell cycle regulator proteins, angiogenesis, chronic inflammation, environmental influences, and other factors for the risk of inverted papilloma. Materials and Methods. A search was made in databases, such as SCOPUS, PubMed, Google Scholar, and RSCI, using the following keywords: Sinonasal papilloma, inverted nasal papilloma, Schneiderian papilloma. Results and Discussion. Human papillomavirus is considered the main growth trigger of inverted papilloma. Potential role of human papillomavirus in initiating the tumor growth is related to the presence in its genome of genes encoding the E6 and E7 proteins. Certain cell cycle regulatory factors and angiogenic proteins contribute to the dysregulation of proliferation and apoptosis and facilitate cell migration and tumor invasion. However, despite the frequent detection of human papillomavirus DNA and associated transcription factors in inverted papilloma tissues, significance of the papillomavirus infection in the occurrence of inverted papilloma or its transformation into malignant forms has not been proven reliably yet. It should be noted that human papillomavirus stimulates not only apoptosis inhibition and the uncontrolled division of epithelial cells, but also angiogenesis, which is also a tumor growth trigger. Among other pathogenic factors, we also discussed the importance of chronic inflammation, smoking, occupational hazards, and industrial environmental pollution. Conclusions. Though etiology of sinonasal inverted papilloma remains controversial, the studies reviewed here indicate the importance of viral infection, cell cycle and angiogenic factors, environmental and occupational exposure, and chronic inflammation. Further studies on etiologic factors are required to ensure better clinical guidance and therapeutic targets.

Synergizing policies for carbon reduction, energy transition and pollution control: Evidence from Chinese power generation industry

To mitigate climate change and achieve sustainable development, Chinese governments have introduced “1+N” “dual-carbon” policy system aimed at reducing CO2 emissions, transforming energy structures and controlling pollution. An effective policy mix and synergy is crucial for achieving the emission reduction targets and for ensuring the effectiveness of the policies, and it is therefore of great practical importance to provide a pathway for policy synergy based on assessing policy effectiveness. This paper selects three policies, namely the carbon Emission Trading System (ETS), Coal Control and Clean Utilization (CCCU), and Green Financial Reform and Innovation Pilot Zone (GFPZ), sets up ten scenarios, adopts difference-in-differences (DID) models to evaluate the impact, and give a pathway for policy synergy. The results show that ETS, CCCU, and GFPZ policies have significant positive effects on carbon emission reduction, energy structure transformation, and industrial environmental pollution control, respectively; CCCU has synergistic effects with ETS and GFPZ policies in controlling coal consumption and increasing the completion of industrial pollution control investments, respectively; while GFPZ policies have conflicting effects with CCCU and ETS in reducing carbon emissions and coal consumption, the GFPZ policy has conflicting effects with CCCU and ETS in reducing carbon emissions and controlling coal consumption. Finally, the study proposes a phased policy support system around carbon emission reduction in the power generation industry, energy structure transformation, and industrial environmental pollution control before 2030 and from 2030 to 2060.

Can digitalization reduce industrial pollution? Roles of environmental investment and green innovation

Industrialized nations have witnessed a decline in environmental quality over the years. The potential of digitalization in mitigating environmental pollution is of significant interest. Drawing on firm-level data from listed Chinese companies between 2010 and 2020, including pollutant and financial metrics, this study investigates the influence of digitalization on industrial environmental pollution. We found that digitalization substantially diminishes the intensity of industrial pollution emissions. These findings hold even after employing instrumental variable tests, substituting the dependent variable with carbon dioxide emissions, and conducting a quasi-natural experiment in intelligent manufacturing. Moreover, our exploration of the underlying mechanisms reveals that the decline in pollution emission intensity attributable to digitalization stems from both structural and technological factors; specifically, it enhances environmental investment and fosters green innovation. The benefits of digitalization in curbing emission intensity are pronounced for firms characterized by lower pollution levels, executive leadership with environmental work backgrounds, heightened capital intensity, and elevated media coverage.

Evaluation of the triangle-relationship of industrial pollution, foreign direct investment, and economic growth in China’s transformation

Unlike previous research on foreign direct investment (FDI), economic growth, and pollution, this study focuses on investigating complex interactions specifically. A dynamic simultaneous equation model is adopted, together with the one-step systematic GMM, drawn upon to empirically analyze 30 Chinese provinces between 2006 and 2017. The results show that FDI does promote economic growth in China which, in turn, positively affects FDI. However, FDI inflow and economic growth both have negative environmental effects. A higher level of environmental pollution corresponds with FDI becoming more attractive. In the case of China, therefore, the pollution-haven hypothesis holds weight. Specifically, industrial environmental pollution is found to positively affect economic growth, indicating this growth to fall on the left side of the environmental Kuznets Curve. Accordingly, therefore, policymakers should look to optimize China’s industrial structure, guide the inflow of high-quality FDI, and promote healthy and sustainable development under the country’s new development philosophy.

Phenol Degradation by Pseudarthrobacter phenanthrenivorans Sphe3

Phenol poses a threat as one of the most important industrial environmental pollutants that must be removed before disposal. Biodegradation is a cost-effective and environmentally friendly approach for phenol removal. This work aimed at studying phenol degradation by Pseudarthrobacter phenanthrenivorans Sphe3 cells and also, investigating the pathway used by the bacterium for phenol catabolism. Moreover, alginate-immobilized Sphe3 cells were studied in terms of phenol degradation efficiency compared to free cells. Sphe3 was found to be capable of growing in the presence of phenol as the sole source of carbon and energy, at concentrations up to 1500 mg/L. According to qPCR findings, both pathways of ortho- and meta-cleavage of catechol are active, however, enzymatic assays and intermediate products identification support the predominance of the ortho-metabolic pathway for phenol degradation. Alginate-entrapped Sphe3 cells completely degraded 1000 mg/L phenol after 192 h, even though phenol catabolism proceeds slower in the first 24 h compared to free cells. Immobilized Sphe3 cells retain phenol-degrading capacity even after 30 days of storage and also can be reused for at least five cycles retaining more than 75% of the original phenol-catabolizing capacity.

Study and Realization of Environmental Health Diagnosis by Using Nanomaterial Based Fiber Optic Sensor–A Review

In these days, the significance of fiber optic sensors has exceptionally increased due to technological advances in modern society. Nowadays, researchers are attracted toward the development of a sensor that possesses the integration of both fiber optic sensors and nanocomposite thin film to improve the sensor’s performance. Thin-film nanomaterial based optical fiber sensors have great potential applications, namely, gas sensing, chemical sensing, biomolecules, food plant, industrial hazards, safety issues, drug monitoring, and heavy metal detections. There are various techniques, namely, evanescent field absorption spectroscopy, fiber Bragg grating (FBG), long-period grating (LPG), ringdown spectroscopy, surface plasmon resonance (SPR), Mach–Zehnder interferometer (MZI) techniques, and so on, which are used for the development of fiber optic sensors that are majorly emphasized in the current article. Numerous scientific researchers have demonstrated that functionalized fiber optic sensors are found more beneficial in terms of improvement of the sensing performance, such as sensitivity, repeatability, response time, specificity, recovery time, and repeatability. Henceforth, in this review article, we have focused on these requisite sensing parameters in detail. Furthermore, to keep human beings healthy, it is our responsibility to develop a sensor that can monitor the optimum toxic concentrations accurately. Thus, the monitoring of industrial environmental pollutants, such as NH3, ethylenediamine, alcohol, and acetone, is immensely important to save human lives on Earth. In the report, all the details of the target analytes, such as optimum concentrations, adverse effects on human beings, and monitoring techniques, are discussed.

Urban and industrial environmental pollution control in China: An analysis of capital input, efficiency and influencing factors

With rapid urbanization and industrialization, environmental pollution caused by such activities has drawn much attention due to its adverse impacts on environmental quality and public health. Therefore, under the current background of China's ecological civilization construction, promoting the precise and scientific treatment of environmental pollution holds great significance. This paper proposes an improved perpetual inventory method to systematically measure the capital stock of urban and industrial pollution control. The efficiency of urban and industrial pollution control is measured by adopting the global data envelopment analysis (DEA) model. Then, the influencing factors of pollution control efficiency are empirically analyzed by using the spatial Tobit regression model. The results reveal that, first, the growth rate of the capital input scale of urban pollution control is greater than that of industrial pollution control, and the spatial distribution of capital input is unbalanced. Second, the efficiency of urban and industrial pollution control from 1991 to 2019 was generally low. The current efficiency values of urban and industrial pollution control are less than 0.2 and 0.5, respectively, indicating that urban and industrial pollution control are far from efficient. Third, the efficiency of urban and industrial pollution control is significantly positively related to the level of urbanization and industrialization, has a U-shaped relationship with the economic development level, and has heterogeneous effects on technology, energy intensity, government influence and foreign trade. On this basis, we provide constructive suggestions for optimizing the performance of pollution control.

Synthesis and Application of Activated Carbon Magnetic Nanocomposite Modified by Calcium Oxide for Removal of Malachite Green dye from Aqueous Solution: Isotherm and Kinetic Study of Adsorption Process

Dyes are one of the most important industrial environmental pollutants, and therefore their removal from industrial wastewater is very important. The malachite green is a very toxic dye for the environment and humans, therefore an economical and high-efficiency method to remove this dye from water solutions is necessary. In this study, the removal of malachite green was investigated using a economical and effective adsorbent, in which activated carbon from date kernel was used. Activated carbon from date kernel was modified by Fe3O4 magnetic nanoparticles and calcium oxide. The properties and characteristics of these adsorbents were investigated using FTIR, VSM, TGA, XRD and SEM analyzes. Parameters affecting the adsorption process such as pH, adsorbent dosage, contact time and initial concentration of malachite green were optimized. Equilibrium and kinetic study of adsorption process was performed using common models. The results showed optimal conditions for adsorption of malachite green using the adsorbent are: initial concentration equal to 10 mg/l, pH=7, contact time equal to 20 minutes, adsorbent dose for AC, AC/Fe3O4 and AC/Fe3O4/CaO equal to 3, 3 and 2 g/l, respectively. The Freundlich model also has a higher ability to describe process equilibrium behavior and the pseudo-second-order kinetics model has a good ability to express reaction kinetics. The Langmuir adsorption capacity of malachite green by the AC, AC/Fe3O4 and AC/Fe3O4/CaO was determined to be 50.9 mg/g, 85.7 mg/g and 107.4 mg/g respectively. The desorption and reuse ability of AC/Fe3O4/CaO was investigated up to 8 steps, which showed that the adsorbent has the ability to be reused several times in the adsorption process. The results showed that modification of activated carbon with magnetic Fe3O4 nanoparticles and calcium oxide increases its adsorption efficiency and makes it a suitable adsorbent for commercialization.

A three-player game analysis on industrial environmental pollution control

The environmental pollution of industrial enterprises has severely restricted the development of economy and society. In the face of serious industrial environmental pollution, this paper constructs a three-player game model including enterprises, government and the public, and conducts a balanced analysis on the interests of the three parties in enterprise environmental pollution control. The results show that the regulation effect of pollutant discharge punishment on industrial enterprises is better than that of pollution control subsidies, and the system with high fines and high subsidies will reduce the enthusiasm of enterprises to comply with regulations.

Decoupling between industrial environmental pollution and industrial economic growth in Guangxi Beibu Gulf Economic Zone

In order to gain a deeper understanding of the decoupling change trajectory of the industrial environment pollution and industrial economic growth in Guangxi Beibu Gulf Economic Zone, and to better solve the problem of sustainable economic development under the concept of low-carbon economy, based on the decoupling theory, six major indicators such as COD, ammonia nitrogen, SO2, NOx, PM and industrial added value were selected to conduct the empirical analysis of the decoupling relationship between industrial environmental pollution and industrial economic growth in Guangxi Beibu Gulf Economic Zone from 2009 to 2016. The results showed that they were basically in an unstable state of incomplete decoupling, most of which were manifested as strong decoupling, accompanied by other types of decoupling, and no obvious evolutionary law. In terms of time, the decoupling reached its best in 2013 and 2016. In terms of space, the decoupling in Nanning was the best.

Variability of Platanus orientalis leaves under a heterogeneous environment in the Hissar Valley of Tajikistan

Geospatial monitoring of leaves variability has been performed for Platanus orientalis L. (Platanaceae) in Hissar Valley of Tajikistan. 17 local populations were clustered in four territorial groups and investigated by 11 morphometric variables and four indices. Six levels of variability were taken in the classification of S.A. Mamaev. All tested parameters were ranked due to the total score of variability levels. It was established, that indicators which have the combination of high, increased, and medium levels of variability, can be recommended for the purpose of geospatial monitoring. In the studied set of variables are two such ones: (1) the ratio of the length of leaf blade to the lengh of petiole, and (2) the petiole lengh. These two indicators reliably respond to point sources of industrial environmental pollution (Aluminum and Cement factories). Six indicators with domination of the middle level of variability, are of diagnostic value to differ loci inside territorial groups of populations. The results of the experiment confirmed, that set of variability levels for 8 of 15 studied parameters has diagnostic matter for geospatial monitoring of environment conditions in Hissar Valley of Tajikistan.

The government capacity on industrial pollution management in Shanxi province: A response impulse analysis

This study employs the Vector Auto-regression model with Generalized Response Impulse Function to analyse the dynamic nexus between economic growth and the industrial environmental pollution intensity for six specific pollutants in Shanxi province of China from 1995 to 2015. The result show there exists bi-directional effects, with stronger impact running from economic development to industrial pollution is stronger. We also find the Shanxi government shows significant capacity in the management of industrial solid waste and waste gas. The provincial government has higher capacity in controlling Sulfur Dioxide compared to soot/dust. Our results verify the existence of Environmental Kuznets Curve through dynamic interactions between industrial pollution intensity and economic growth impulse. Three out of the six environmental pollution intensity responses are in the shape of inverted U curve. There are exceptions for three pollutants: N curve for Chemical Oxygen Demand and U curve for solid waste and waste gas.

Industrial pollution resulting in mass incidents: Urban residents' behavior and conflict mitigation

Industrial environmental pollution often entails conflicts of interest; therefore, it is more likely than many other factors to result in a mass incident and challenge sustainable development and cleaner production. Employing an adaptive agent-based model, this study explored mass incidents from the perspective of residents' behavior, influencing factors, and conflict mitigation policies. Results from the simulation model revealed three types of residents' behavior: no behavior, lawful behavior, and extreme behavior, moreover, residents' behavior changed slightly as their legal awareness increased. Similarly, the timing of government actions and the speed with which firms responded to environmental grievances related to their practices did not clearly affect residents' behavior. In contrast, other factors—such as satisfaction with the compensation awarded, levels of pollution health risk, and the speed at which rumors were propagated—affected their behavior dramatically. Findings could be incorporated into governmental decision-making to help alleviate environmental pollution conflicts.

Fabrication uniform hollow Bi2S3 nanospheres via Kirkendall effect for photocatalytic reduction of Cr(VI) in electroplating industry wastewater

Hazardous hexavalent chromium removal from wastewater is an urgent issue in industry environmental pollution. In this work, hollow Bi2S3 nanospheres have been successfully synthesized from unique Bi2O3 porous nanospheres via Kirkendall effect through hydrothermal process. It was found that the sulfur source and the initial Bi2O3 templates played key roles in the formation of the uniform morphologies and structures through an anion exchange process. Compared with other Bi2S3 samples, the synthesized hollow Bi2S3 nanospheres exhibited much enhanced photocatalytic ability for Cr(VI) photoreduction. XPS analysis demonstrated that Cr(VI) was reduced to less harmful Cr(III) species over hollow Bi2S3 nanospheres under visible-light irradiation. More importantly, the hollow Bi2S3 nanospheres remained high efficiency and good stability in the recycling Cr(VI) photoreduction, and exhibited remarkable Cr(VI) removal ability in actual electroplating industry wastewater treatment.

Biological effects of high copper and zinc concentrations and their interaction in rapeseed plants

In experiments with rapeseed (Brassica napus L., cv. Westar) plants, it was confirmed that copper was considerably more toxic than zinc. The toxic effects of 50 and 150 μM CuSO4 were comparable to those of 1000 and 2500 μM ZnSO4. The analysis of the effects of these concentrations of copper and zinc on photosynthetic pigment contents and on the rate of lipid peroxidation did not reveal any reasons for different toxicities of these heavy metals (HM). Among biological effects studied, significant differences were found in the organ distribution of these metals in plants grown on both the standard medium and the medium with high concentrations of copper or zinc. Copper retained in the roots in relatively small amounts and was poorly transported over the aboveground part of the plants. It stayed mainly in the lower leaves, and its distribution changed only a little during the recovery of plants following the HM treatment. In contrast, zinc proved to be highly mobile, it was concentrated in the upper leaves and actively transported when the plants were transferred to a medium with the optimal HM concentrations. High copper concentrations slowed strongly zinc uptake by the roots but practically did not change its movement over the plant. In contrast, high zinc concentrations facilitated copper uptake by the roots but reduced its transfer to the aboveground organs. The data presented here allow us to hypothesize that biological peculiarities of organ and cellular distribution of copper and zinc in plants and interaction of these HM play an important role in the toxic effects of high concentrations of these HM and the mechanisms of adaptation to them at industrial environmental pollution used by rapeseed plants.
