Complexo-titrimetric determination of mercury using hexahydropyrimidine-2-thione as a selective masking agent

Chinese Journal of Chemistry 1992年第5期10卷 412-416页

A simple, rapid, accurate and selective complexometric method is proposed for the determina- tion of mercury(Ⅱ). Mercury(Ⅱ) is first complexed with a known excess of EDTA and the surplus EDTA is back-titrated at pH 5. 0--6. 0 with lead nitrate, xylenol orange being used as indicator. Hexa- hydropyrimidine-2-thione (HPT) is then added to displace EDTA from the Hg-EDTA complex quan- titatively and the EDTA released is titrated with lead nitrate. Reproducible and accurate results are obtained for 2--55 mg of mercury, with a relative error of less than 0. 5% and standard deviation of less than 0.04.

Understanding the molecular mechanisms of cancer prevention by dietary phytochemicals:From experimental models to clinical trials

引用

World Journal of biological Chemistry 2016年第1期7卷 88-99页

作者： girish b Maru Rasika R Hudlikar Gaurav Kumar Khushboo Gandhi Manoj b Mahimkar Advanced Centre for Treatment Research and Education in Cancer (ACTREC)Tata Memorial Centre (TMC)

Chemoprevention is one of the cancer prevention approaches wherein natural/synthetic agent(s) are prescribed with the aim to delay or disrupt multiple pathways and processes involved at multiple steps, i.e., initiation, promotion, and progression of cancer. Amongst environmental chemopreventive compounds, diet/beverage-derived components are under evaluation, because of their long history of exposure to humans, high tolerability, low toxicity, and reported biological activities. This compilation briefly covers and compares the available evidence on chemopreventive efficacy and probable mechanism of chemoprevention by selected dietary phytochemicals(capsaicin, curcumin, diallyl sulphide, genistein, green/black tea polyphenols, indoles, lycopene, phenethyl isocyanate, resveratrol, retinoids and tocopherols) in experimental systems and clinical trials. All the dietary phytochemicals covered in this review have demonstrated chemopreventive efficacy against spontaneous or carcinogen-induced experimental tumors and/or associated biomarkers and processes in rodents at several organ sites. The observed anti-initiating, anti-promoting and anti-progression activity of dietary phytochemicals in carcinogen-induced experimental models involve phytochemical-mediated redox changes, modulation of enzymes and signaling kinases resulting to effects on multiple genes and cell signaling pathways. Results from clinical trials using these compounds have not shown them to be chemopreventive. This may be due to our:(1) inability to reproduce the exposure conditions, i.e., levels, complexity, other host and lifestyle factors; and(2) lack of understanding about the mechanisms of action and agent-mediated toxicity in several organs and physiological processes in the host. Current research efforts in addressing the issues of exposure conditions, bioavailability, toxicity and the mode of action of dietary phytochemicals may help address the reason for observed mismatch that may ultimately lead

Isolation of Multi-Drug Resistant Paenibacillus sp. from Fertile Soil： An Imminent Menace of Spreading Resistance

Journal of Life Sciences 2010年第5期4卷 15-19页

There are a good number of reports in the literature stating spread of resistance from normal soil flora to nosocomial microorganism through various ways. Similarly during the study of antimicrobial susceptibility pattern in the microflora, a multidrug resistant bacterium has been isolated from soil collected in Maharashtra state （India）. The bacterium exhibited a resistance to various classes of antibiotics namely glycopeptide, beta-lactams, aminoglycosides, macrolides and lincosomides. The bacterial strain showed its resemblance to the genus Paenibacillus. This constitutes the first report of its kind as to the multi-drug resistance trait in the genus Paenibacillus phenotype, especially in close phylogenetic neighbour of Paenibacillus daejeonensis. The resistance pattern displayed by this strain particularly highlights the possible presence of multiple resistant determinants in microflora of the soil rhizosphere. In view of the recent reports about the Paenibacillus spp. in clinical derived strains, such multi-drug resistance factors in this genus adds to menace of transmission of resistance to common soil originating pathogen. The data also supports the fact that the resistances to certain antibiotics need not always be due to exposure to particular antibiotic or similar substance.

Pleistocene Radiolaria from Leg 119 Site 738b (Sections 1H1-1H2): Systematics and biostratigraphy

引用

Open Journal of Geology 2013年第8期3卷 427-438页

作者： girish Kumar Sharma Sheetal Kanojia Department of Geology Kumaun University Nainital India

This paper presents a record of radiolarian species from the sections (1H1-1H2) Leg 119 Site 738b of Southern Ocean region. Well diversified taxa of typical Antarctic assemblage are present in the sections. Thirty species were identified and illustrated from twenty-nine samples. On the basis of appearance, disappearance and abundance of taxa, viz. Omega and Psi zones are established and systematics of stratigraphically important species is described. These zones are equivalent to NR1 and NR2 of Upper Quaternary.
