Type 2 inflammation is a complex immune response and primary mechanism for several common allergic diseases including allergic rhinitis,allergic asthma,atopic dermatitis,and chronic rhinosinusitis with nasal polyps.It is the predominant type of immune response against helminths to prevent their tissue infiltration and induce their expulsion.Recent studies suggest that epithelial barrier dysfunction contributes to the development of type 2 inflammation in asthma,which may partly explain the increasing prevalence of asthma in China and around the globe.The epithelial barrier hypothesis has recently been proposed and has received great interest from the scientific community.The development of leaky epithelial barriers leads to microbial dysbiosis and the translocation of bacteria to inter-and sub-epithelial areas and the development of epithelial tissue inflammation.Accordingly,preventing the impairment and promoting the restoration of a deteriorated airway epithelial barrier represents a promising strategy for the treatment of asthma.This review introduces the interaction between type 2 inflammation and the airway epithelial barrier in asthma,the structure and molecular composition of the airway epithelial barrier,and the assessment of epithelial barrier integrity.The role of airway epithelial barrier disruption in the pathogenesis of asthma will be discussed.In addition,the possible mechanisms underlying the airway epithelial barrier dysfunction induced by allergens and environmental pollutants,and current treatments to restore the airway epithelial barrier are reviewed.

Pedosphere 2022年第1期32卷 49-60页

作者： Paramdeep KAUR Kashmir SINGH Baljinder SINGH Department of Biotechnology Panjab UniversityChandigarh 160014India

Microplastics(MPs) are plastic particles less than 5 mm in size that have become a major environmental pollutant due to their ubiquitous and persistent nature. Microplastic contamination of the aquatic environment has received the most attention so far, whereas the current understanding of MP prevalence and its impacts in the terrestrial environment is largely limited. The MP contamination of soil can cause bioaccumulation and toxicity in terrestrial animals and plants, which can consequently affect human health. This review is aimed towards combining the available information on the occurrence, sources, and effects of MPs on the different aspects of the terrestrial environment and to highlight the limitations in our knowledge regarding the nature and impacts of MPs in soil. The review also highlights microbial degradation of MPs as an advancing research area, with numerous microorganisms being identified as capable of efficiently degrading this persistent contaminant.

The fast increase of population results in the quick development of industry and agriculture.Large amounts of contaminants such as metal ions and organic contaminants are released into the natural environment,posing a risk to human health and causing environment ecosystem problems.The efficient elimination of contaminants from aqueous solutions,photocatalytic degradation of organic pollutants or the in-situ solidification/immobilization of heavy metal ions in solid phases are the most suitable strategies to decontaminate the pollution.Biochar and biochar-based composites have attracted multidisciplinary interests especially in environmental pollution management because of their porous structures,large amounts of functional groups,high adsorption capacities and photocatalysis performance.In this review,the application of biochar and biochar-based composites as adsorbents and/or catalysts for the adsorption of different contaminants,adsorption-photodegradation of organic pollutants,and adsorption-(photo)reduction of metal ions are summarized,and the mechanism was discussed from advanced spectroscopy analysis and DFT calculation in detail.The doping of metal or metal oxides is the main strategy to narrow the band gap,to increase the generation and separation of photogenerated e−-h+pairs,to produce more superoxide radicals(·O_(2)^(−))and hydroxyl radicals(·OH),to enhance the visible light absorption and to increase photocatalysis performance,which dominate the photocatalytic degradation of organic pollutants and(photo)reduction of high valent metals to low valent metals.The biochar-based composites are environmentally friendly materials,which are promising candidates in environmental pollution cleanup.The challenge and perspective for biochar-based catalysts are provided in the end.

Biological Degradation of Some Organic Compounds Enrolled in Paper Industry—A Pollution Prevention Approach

引用

Biomedical and environmental Sciences 2000年第1期13卷 56-68页

作者： RIFAATABDELWAHAAB WaterPollutionResearchDepartment NationalResearchCentre

Evaluation of the elimination and the “ultimate” biodegradation by aerobic microorganisms of some organic compounds commonly used in paper manufacturing technology was investigated. Biodegradation lines of nine organic compounds were determined as percentage removal of chemical oxygen demand (COD) over 7 days incubation. The results of the biodegradability test clearly revealed that some of the organic compounds under investigation are highly biodegradable, while others rank from fairly to even non biodegradable. Significant biodegradation results were recorded for anti coating ester (95.0%), basoplast 200D (85.3%) and basoplast PR 8050(87.6%). A bleaching agent (formamidin sulfinic acid), ukanol BSA and solidurit KM demonstrate moderate biodegradation results of 62.1%, 76.2% and 69.8%, respectively. Poor biodegradation results for Hedifix M/35 (12.7%), basazol orange (34.9%) and basazol brown (29.0%) were recorded. Accordingly, appropriate precaution should be taken into consideration when using these compounds for industrial applications.

Biosynthesis of polyhydroxyalkanoates from styrene by Enterobacter spp. isolated from polluted environment

引用

Frontiers in Biology 2017年第3期12卷 210-218页

作者： Arooj Arshad Bisma Ashraf Iftikhar Ali Nazia Jamil Department of Microbiology and Molecular Genetics University of the Punjab Quaid-e-Azam Campus Lahore-54590 Pakistan

BACKGROUND： Styrene and its metabolites are known to have serious adverse effects on human health and hence, strategies to prevent its release, eradicate it from the environment, and understand its route of degradation are being considered. METHODS： A total of 18 strains were isolated from 4 samples of diesel contaminated soils. Among them 5 strains were selected for their ability to degrade styrene and use it as a sole carbon source to produce PHA. These strains were identified as Enterobacter spp. on the basis of 16S rRNA gene sequencing. Bacteria were screened for their ability to produce PHA by utilizing glucose and styrene as a carbon sources. Screening for PHA production was done by Nile blue A, Sudan black B, and phase contrast microscopy and the selected 3 strains showed positive results. Growth kinetics along with time profiling of PHA was performed for glucose and styrene as carbon sources. RESULTS： PHA extraction was done at equal intervals of 12 h by sodium hypochlorite method which showed that these strains accumulate maximum amount of PHA after 48 h in glucose （30.60%）. FTIR analysis of PHA was done which revealed homopolymer PHB and copolymer （PHB-co-PHV） production in strains by utilizing glucose and styrene. Gas chromatography mass spectrometry was carried out to identify the metabolites produced by bacterial strains grown on styrene. Metabolites of styrene degradation included propyne and phenylalanine. Genomic DNA isolation was carried out to amplify phaC gene which encodes PHA synthase enzyme. CONCLUSIONS： The conversion of styrene to polyhydroxyalkanoates （PHA） provides a new and unique link between an aromatic environmental pollutant and aliphatic PHA accumulation.

Journal of Integrative Medicine（双语） 2021年第2期10卷 60-74页

作者： Sylvia Frisancho-Kiss Department of Anesthesiology and Intensive Care Hospital KomárnoSlovakia

During the past decades,populous expansion in mast cell scientific literature came forth with more,than forty-four thousand PubMed publications available to date.Such surge is due to the appreciation of the momentous role of mast cells in the evolution of species,in the development and maintenance of vital physiological functions,such as reproduction,homeostasis,and fluids,diverse immunological roles,and the potential of far-reaching effects despite minute numbers.While the emerging knowledge of the importance of mast cells in equilibrium comes of age when looking at the matter from an evolutionary perspective,the recognition of mast cells beyond detrimental performance in allergies and asthma,during protection against parasites,falters.Beyond wellknown classical functions,mast cells can process and present antigens,can serve as a viral reservoir,can respond to hormones and xenobiotics,initiate antiviral and antibacterial responses,phagocytosis,apoptosis,and participate in important developmental cornerstones.During evolution,upon the development of a sophisticated niche of innate and adaptive cell populations,certain mast cell functions became partially transmutable,yet the potency of mast cells remained considerable.Reviewing mast cells enables us to reflect on the certitude,that our sophisticated,complex physiology is rooted deeply in evolution,which we carry ancient remnants of,ones that may have decisive roles in our functioning.This communication sets out the goal of characterizing mast cells,particularly the aspects less in limelight yet of immense significance,without the aspiration exhaust it all.

4-Octylphenol（4-OP） is a common biodegradation product of a widely used group of non-ionic surfactants,the octylphenolpolythoxylates（OPEOs）.However,compared to these parent compounds that have been extensively used in many industrial sectors including textile,petroleum and paper production,octylphenol is known to be more persistent and estrogenically active.In this study,14 filamentous fungi were isolated from soil,water and sludge samples collected from waste water treatment plant in Taipei and plastic industry waste water in Taoyuan.The isolates belong to six genera such as Aspergillus（2 spp.）,Fusarium（6 spp.）,Nectriaceae（2 spp.）,Pseudallescheria,Scedosporium,Trichoderma（2 spp.）.Of 14 fungal isolates,10 strains grew effectively on solid medium with a wide variety of endocrine disrupting chemicals such as nonylphenol,octylphenol,octylphenolpolyethoxylate,estrone,17P-estradiol and 17a-ethnylestradiol.For further screening,the percentage of octylphenol degradation was determined using HPLC analysis.All the 10 fungi were able to degrade and utilize octylphenol as the sole carbon source.To our knowledge,this is the first report of octylphenol degradation by filamentous fungi.In 14 days,the most effective degradation（＞70%） was observed in three strains of Fusarium solani.In Fusarium oxysporum（2strains） and Fusarium sp.,the degradation rate was around 65%.In the other strains such as those of Aspergillus and Trichoderma,55%degradation was observed.Given that the most effective degradation potential was observed in Fusarium solani,this species is currently under further studies.
