| 1 | Contribution of microbial phytases to the improvement of plant growth and nutrition: A review显示文摘Phytases belong to the class of phosphohydrolases that begin the step-wise hydrolysis of phosphates from phytates. Phytates are a derivative of myo-inositol, which is the primary storage form of organic phosphorus in plant cells. Phytase has been used globally to diminish phosphorus pollution and to enhance nutrition in monogastrics. In this review, the classification, sources, and diversity of microbial phytases, and their practical applications, as well as supplementation of the soil with transgenic and wild types of microbial strains, which can release phytase to enhance phosphorus availability for plant uptake and reduce the need for fertilizers, are discussed. The overexpressed microbial phytases in transgenic plants enhance the growth capacity of co-cultivated plants and can therefore be employed in agricultural and biotechnological practices, such as intercropping. The introduction of phytases into the soil for improved plant growth and enhanced crop yield can be accomplished without extra cost. A diverse group of photoautotrophic microalgae can synthesize phytase and will likely be useful in many human food and animal industries. | Bijender SINGH Ines BOUKHRIS PRAGYA Vinod KUMAR Ajar Nath YADAV Ameny FARHAT-KHEMAKHEM Anil KUMAR Davender SINGH Monia BLIBECH Hichem CHOUAYEKH Othman AALGHAMDI | 2020 | Pedosphere2020，30，3： | 2 |
| 2 | In vivo antianxiety and antidepressant activity of Murraya paniculata leaf extracts显示文摘OBJECTIVE: Different parts of Murraya paniculata have been used traditionally for treating several ailments including mental disorders. The present study was designed to evaluate the antianxiety and antidepressant potential of M. paniculata leaves using elevated plus maze model and forced swim test, respectively.METHODS: Extracts of M. paniculata made with petroleum ether(60–80 °C), chloroform, ethanol and water were evaluated for antianxiety and antidepressant activity. The anxiolytic chloroform extract was subjected to column chromatography, yielding five fractions(F_1–F_5). Fraction F_5(100 mg/kg), which showed notable anxiolytic activity, was further chromatographed to get four subfractions(F_(5.1)–F_(5.4)). Simultaneously, the ethanol extract was partitioned with ethyl acetate to obtain ethyl acetate soluble fraction(EASF) and ethyl acetate insoluble fraction. Phytochemical screening of bioactive extracts/fractions and detection of mahanimbine in M. paniculata leaf extract by thin-layer chromatography was also carried out.RESULTS: Fraction F_(5.3)(25 mg/kg) and EASF(20 mg/kg) showed significant anxiolytic and antidepressant activity, respectively. Thin-layer chromatography and phytochemical screening demonstrated the absence of mahanimbine in M. paniculata leaves. Coumarins were observed to be responsible for the anxiolytic activity.CONCLUSION: The results validate the traditional use of M. paniculata leaves in the treatment of mental disorders. | Pragya Sharma Sonali Batra Ashwani Kumar Anupam Sharma | 2017 | Journal of Integrative Medicine2017，15，4： | 2 |

| 7 | Mental health service users'progression from illicit drug use to schizophrenia in New Zealand显示文摘Background Recently,publications have hypothesised that the demonstrated increase in the incidence of schizophrenia in New Zealand is a side effect of the increased strength of available cannabis derivatives over the last 25+years and the much more recent increase in the population's use of methamphetamine.Aim To compare the rates of later schizophrenia between age-matched mental health service users with initial diagnoses as alcohol abusers or illicit drug users.Method From the PRIMHD comprehensive national database,all users of the mental health services over a 5-year period who received an ICD-10 presenting diagnosis of alcohol or substance use/abuse were identified.For each person identified,the database was examined for the following 3 years to determine the numbers later diagnosed with schizophrenia.Results For the initial alcohol problem people in their twenties,1.7%were diagnosed as suffering from schizophrenia in the subsequent 3 years.For the initial drug problem people,the rate was 10.9%.Within that drug-using population,the indigenous Maori developed schizophrenia at a higher rate than did the remainder of the population.Conclusion These findings in New Zealand require further research into their generalisability,context and explanation. | Graham Mellsop Rees Tapsell Pragya Holmes | 2019 | General Psychiatry2019，32，5： | 1 |
