In Vitro Anti Inflammatory, Anti-Oxidant and Anti-Cancer Cell Line Studies on Mollugo Cerviana (L.) Ser

Our traditional treatises on medicine have shown references to number of rare medicinal herbs prescribed to treat various ailments in human. An herbal plant preferred to treat fever, inflammation, rheumatic pain and wounds prevalently in the villages of the delta districts of Tamilnadu by name Mollugo cerviana was chosen for this research. The Ethanol extract of Mollugo cerviana was analysed for its in vitro anti-inflammatory, antioxidant and anticancer activity through standard procedures. The anti-inflammatory activity of the ethanol ethanolic extracts of varying concentrations were evaluated under HRBC (Human Red Blood Cell) Membrane Stabilization and Protein denaturation studies. Diclofenac sodium a nonsterioidal anti-inflammatory drug was the reference standard. The results revealed a concentration dependent increase in the percentage of membrane stabilization activity with increase in concentration of the test extract and a concentration dependent inhibition of protein (albumin) denaturation activity. Antioxidant studies revealed a significant free radical scavenging activity by the extract upon evaluation by DPPH free radical scavenging assay, nitric oxide assay and hydrogen peroxide radical scavenging activity assay. The studies on liver cancer cell lines using MTT assay revealed the anticancer activity exhibited by the ethanol extract of Mollugo cerviana. The studies as a whole reveals the anti-inflammatory, antioxidant and anticancer activity possessed by the herbal extract of Mollugo cerviana which invites attention to proceed with further research towards development of novel herbal drugs from Mollugo cerviana to treat inflammation and cancer

The Eccentric-distance Sum of Some Graphs

Let $G = (V,E)$ be a simple connected graph. Theeccentric-distance sum of $G$ is defined as\xi^{ds}(G) =\ds\sum_{\{u,v\}\subseteq V(G)} [e(u)+e(v)] d(u,v), where $e(u)$ %\dsis the eccentricity of the vertex $u$ in $G$ and $d(u,v)$ is thedistance between $u$ and $v$. In this paper, we establish formulaeto calculate the eccentric-distance sum for some graphs, namelywheel, star, broom, lollipop, double star, friendship, multi-stargraph and the join of $P_{n-2}$ and $P_2$

Efficient Ranked Keyword Using AML

Entity Recognition is process of identifying predefined entities such as person names, products, or locations in a given docu ment. This is done by finding all possible substrings from a document that match any reference in the given entity dictionary. Approximate Membership Extraction (AME) method was used for finding all substrings in a given document that can approximately match any c lean references but it generates many redundant matched substrings because of approximation (rough calculation), thus rendering AME is not suitable for real - world tasks based on entity extraction. We propose a web - based join framework which combines a web search along with the approximate membership localization. Our process first provides a top n number of documents fetched from the web using a general search using the given query and then approximate membership localization(AML) is applied on these documents using the clear reference table and extra cts the entities form the document to form the intermediate reference table using Edit distance Vector, Score Correlation

Effects of Dielectrophoresis on Growth, Viability and Immuno-reactivity of Listeria monocytogenes

Dielectrophoresis (DEP) has been regarded as a useful tool for manipulating biological cells prior to the detection of cells. Since DEP uses high AC electrical fields, it is important to examine whether these electrical fields in any way damage cells or affect their characteristics in subsequent analytical procedures. In this study, we investigated the effects of DEP manipulation on the characteristics of Listeria monocytogenes cells, including the immuno-reactivity to several Listeria-specific antibodies, the cell growth profile in liquid medium, and the cell viability on selective agar plates. It was found that a 1-h DEP treatment increased the cell immuno-reactivity to the commercial Listeria species-specific polyclonal antibodies (from KPL) by ~31.8% and to the C11E9 monoclonal antibodies by ~82.9%, whereas no significant changes were observed with either anti-InlB or anti-ActA antibodies. A 1-h DEP treatment did not cause any change in the growth profile of Listeria in the low conductive growth medium (LCGM); however, prolonged treatments (4 h or greater) caused significant delays in cell growth. The results of plating methods showed that a 4-h DEP treatment (5 MHz, 20 Vpp) reduced the viable cell numbers by 56.8–89.7 %. These results indicated that DEP manipulation may or may not affect the final detection signal in immuno-based detection depending on the type of antigen-antibody reaction involved. However, prolonged DEP treatment for manipulating bacterial cells could produce negative effects on the cell detection by growth-based methods. Careful selection of DEP operation conditions could avoid or minimize negative effects on subsequent cell detection performance

Highly Sensitive Detection of Staphylococcus aureus Directly from Patient Blood

Background: Rapid detection of bloodstream infections (BSIs) can be lifesaving. We investigated the sample processing and assay parameters necessary for highly-sensitive detection of bloodstream bacteria, using Staphylococcus aureus as a model pathogen and an automated fluidic sample processing – polymerase chain reaction (PCR) platform as a model diagnostic system. Methodology/Principal Findings: We compared a short 128 bp amplicon hemi-nested PCR and a relatively shorter 79 bp amplicon nested PCR targeting the S. aureus nuc and sodA genes, respectively. The sodA nested assay showed an enhanced limit of detection (LOD) of 5 genomic copies per reaction or 10 colony forming units (CFU) per ml blood over 50 copies per reaction or 50 CFU/ml for the nuc assay. To establish optimal extraction protocols, we investigated the relative abundance of the bacteria in different components of the blood (white blood cells (WBCs), plasma or whole blood), using the above assays. The blood samples were obtained from the patients who were culture positive for S. aureus. Whole blood resulted in maximum PCR positives with sodA assay (90 % positive) as opposed to cell-associated bacteria (in WBCs) (71 % samples positive) or free bacterial DNA in plasma (62.5 % samples positive). Both the assays were further tested for direct detection of S. aureus in patient whole blood samples that were contemporaneous culture positive. S. aureus was detected in 40/45 of culture-positive patients (sensitivity 89%, 95 % CI 0.75–0.96) and 0/59 negative controls with the sodA assay (specificit

Analysis, design and investigation on a new single-phase switched quasi Z-source inverter for photovoltaic application

Abstract: This paper addresses the approach to improve the efficiency of the quasi Z-source inverter. In order to increase the efficiency the reduction of conduction losses is one way to approach. Sequentially to decrease the conduction losses in the quasi z-source inverter the replacement of diode is replacing with switches is proposed which is also called as synchronous rectification. The paper represents basics of the approach, analysis and comparison of the power losses of the traditional and proposed designs of the grid connected PV-system with quasi z-source inverter system. The proposed approach validated on the computer simulations in the MATLAB environment

Family-focused contextual factors associated with lifestyle patterns in young children from two mother-offspring cohorts : GUSTO and EDEN

Background Integrated patterns of energy balance-related behaviours of preschool children in Asia are sparse, with few comparative analyses. Purpose Using cohorts in Singapore (GUSTO) and France (EDEN), we characterized lifestyle patterns of children and investigated their associations with family-focused contextual factors. Methods Ten behavioural variables related to child's diet, walking, outdoor play and screen time were ascertained by parental questionnaires at age 5-6 years. Using principal component analysis, sex-specific lifestyle patterns were derived independently for 630 GUSTO and 989 EDEN children. Contextual variables were organised into distal (family socio-economics, demographics), intermediate (parental health, lifestyle habits) and proximal (parent-child interaction factors) levels of influence and analysed with hierarchical linear regression. Results Three broadly similar lifestyle patterns were identified in both cohorts: "discretionary consumption and high screen time", "fruit, vegetables, and low screen time" and "high outdoor playtime and walking". The latter two patterns showed small differences between cohorts and sexes. The "discretionary consumption and high screen time" pattern was consistently similar in both cohorts; distal associated factors were lower maternal education (EDEN boys), no younger siblings (GUSTO boys) and Malay/Indian ethnicity (GUSTO), while intermediate and proximal associated factors in both cohorts and sexes were poor maternal diets during pregnancy, parents allowing high child control over food intake, snacking between meals and having television on while eating. Conclusions Three similar lifestyle patterns were observed among preschool children in Singapore and France. There were more common associated proximal factors than distal ones. Cohort specific family-focused contextual factors likely reflect differences in social and cultural settings. Findings will aid development of strategies to improve child health.Peer reviewe
