plasma processes are among the emerging technologies for volatile organic compounds (VOCs) sbatoment. Both thermal plasmas and non-equil[brimn plasmas (cold plasmas) are being developed for VOCs clesnup. Particularly, pulsed corona discharges offer several edvantages over conventional VOCs abatement tochniqvee, To optimize the existing technology and to developit further, there is need to understand the mechanlsms involved in plasma chemical reacticms, Furthermore, it is strongly desirable to be able to predict the behavior of new VOCs in non-equillbrlum plasma enviromuent from the data known for a few representative oompounds, Pulsed corona discharge technique is introduced here with dtafion of refevant literature, Fundamental principfes,useful for predicting the VOCs' decomposition behavior, have been worked out from the published literature. Latest developments in the area, targeted to minimize the enersy losses, improve the VOCs destruction efficiency and reduce the generation of unwanted organic and inorganic by-products, are presented.

Phytopharmacological potential of different species of Morus alba and their bioactive phytochemicals:A review

引用

Asian Pacific Journal of Tropical Biomedicine 2017年第10期7卷 950-956页

作者： Fahad Hussain Zohaib Rana Hassan Shafique arif malik Zahid Hussain Institute of Molecular Biology and Biotechnology(IMBB) The University of LahoreRaiwind Road55150LahorePakistan Department of Pharmaceutics Faculty of PharmacyUniversiti Teknologi MARAPuncak Alam CampusBandar Puncak Alam42300SelangorMalaysia

Medicinal plants of Moraceae family have been well-recognized traditionally due to their versatile applications in various fields including agriculture, cosmetic and food as well as in pharmaceutical industries. Their biomedical and medicinal importance is reflected from their broad range of pharmacological activities for treatment of various inflammatory conditions, cancer, infectious diseases, and gastrointestinal disorders. The present review was aimed to summarize and critically discuss the biomedical implications of Morus species, their bioactive compounds, and phytochemicals. Bioactivity guided fractionation of these medicinal plants revealed that different types of bioactive phytochemicals and secondary metabolites such as steroids, saponins, alkaloids, glycosides and phenolic compounds including terpenoids, flavonoids, anthocyanins and tannins were present. The critical analysis of the literature revealed that the aqueous, methanolic, and ethanolic extracts of Morus species and their bioactive compounds exhibit remarkable anti-oxidative,anti-diabetic, anti-stress, nephroprotective, antimicrobial, anti-mutagenic, anticancer,anxiolytic, hepatoprotective, anthelmintic, antimicrobial, immune-modulatory and cholesterol lowering effects. Based on the literature review and bioactivity guided investigation of Morus species and their phytomedicinal effects, we anticipate that these herbal products hold excellent potential for future research.

All human subjects were screened for 4-hydroxynonenal, isoprostane-F2α, 8-hydroxy-2′-deoxyguanosine, vitamin D, luteinizing hormone, follicle stimulating hormone, testosterones, malondialdehyde, superoxide dismutase, catalase, glutathione peroxidase, and nitric ***: The screening analysis revealed that the levels of luteinizing hormone, follicle stimulating hormone, and testosterone were lower in male infertile subjects compared to healthy subjects. Similarly, the levels of vitamin D [(17.17 ± 2.30) ng/mL] and calcium[(6.29 ± 0.31) mg/dL] were significantly lower in infertile groups compared to the normal healthy groups. Moreover, the study revealed that the levels of superoxide dismutase, catalase, and glutathione peroxidase were significantly higher in healthy subjects compared to the infertile ***:Vitamin D exhibits strong relevance to male fertility by maintaining the levels of sex hormones (luteinizing hormone, follicle stimulating hormone, and testosterone), up-regulating the antioxidant defense (superoxide dismutase, catalase, and glutathione peroxidase), and down-regulating the oxidative stress (malondialdehyde, nitric oxide, and inducible nitric oxide synthase species).

Catalyst assisted destruction of trichloro ethylene and toluene in corona discharges

引用

Journal of Environmental Sciences 2000年第1期12卷 9-13页

作者： muhammad arif malik, jiang Xuan\|zhen (Department of Chemistry, University of Zhejiang, Hangzhou 310027, China) Foundation item: National Natural Science Foundation of China (No. 29576261)

Destruction of trichloro ethylene (C 2HCl 3) by pulsed corona discharge reactor packed with alumina pellets and in absence of packing was investigated. Higher conversion of C 2HCl 3 was observed in presence of alumina than in absence of packing. Furthermore CO/CO 2 ratio in the by products was found to shift in favor of CO 2 by alumina compared with absence of packing. Influence of catalyst porosity on C 2HCl 3 destruction and on by product ozone generation during the processing was also studied. Both alumina Ⅰ and alumina Ⅱ show similar improvement in C 2HCl 3 destruction. However, more important observation was that alumina Ⅰ produces higher by product ozone, while, alumina Ⅱ produces lower by product ozone, than in the case of no packing. The catalyst porosity effect was also investigated for destruction of toluene and was found to be similar. Intermediates of C 2HCl 3 destruction, as identified by GC MS, were COCl 2, CH 2Cl 2CHCl 3, CCl 4 and C 2HCl 5. In presence of alumina the amount of these intermediates was much reduced, indicating the catalytic function of alumina.

Efficient hepatoprotective activity of cranberry extract against CCl_4-induced hepatotoxicity in Wistar albino rat model: Down-regulation of liver enzymes and strong antioxidant activity

Asian Pacific Journal of Tropical Medicine 2017年第11期10卷 1054-1058页

Objective: To investigate the hepatoprotective efficacy of cranberry extract(CBE)against carbon tetrachloride(CCl4)-induced hepatic injury using in-vivo animal ***: The hepatoprotective efficacy of CBE(200 and 400 mg/kg) was investigated against CCl4(4 m L/kg)-induced hepatotoxicity, elevated liver enzymes [ALT(alanine aminotransferase), AST(aspartate aminotransferase), and alkaline phosphatase(ALP)],and total protein(TP) contents in the serum. Moreover, CBE-aided antioxidant defense against hepatotoxic insult of CCl4 was measured by evaluating a number of anti-oxidative biomarkers including reduced glutathione(GSH), superoxide dismutase(SOD), catalase(CAT), and malondialdehyde(MDA) in the serum by using spectrophotometric ***: Results showed that the exposure of experimental animals to CCl4 did induce significant hepatotoxicity compared to the non-induced(untreated) group. The oral administration of CBE demonstrated a significant dose-dependent alleviation in the liver enzymes(AST, ALT, and ALP), increased antioxidant defense(GSH, SOD, and CAT),and reduced MDA levels in the serum of treated animals compared to the animals without treatment. The resulting data showed that the administration of CBE decreased the serum levels of ALT, AST, and ALP compared to the CCl4-induced ***: The resulting data evidenced that CBE exhibits promising hepatoprotective potential against the chemical induced hepatotoxicity, maintains homeostasis in liver enzymes, and can provide significant antioxidant defense against free radicals-induced oxidative stress.
