The present study aimed to evaluate the antinociceptive and anti-inflammatory activity of Alangium salvifolium (AS) flower in mice. The antinociceptive activity was determined using tail immerson, acetic acid induced writhing and formalin induced licking test. Antiinflammatory effects were evaluated using carrageenan and formalin induced paw edema in mice. The methanol extract (50 and 100 mg kg-1) of flower of AS followed by chloroform extract (100 mg kg-1) produced a significant inhibition of both phases of the formalin pain test in mice, a reduction in mice writhing induced by acetic acid and delayed the response of mice to hot water thermal stimulation in tail immersion test. All flowers extract of AS also produced a substantial inhibition (nearly 50%) of carrageenan and formalin induced paw edema. The inhibitions were similar to those produced by indomethacin, p.o. The different alkaloids and flavonoids found in the extract could be account for the antinociceptive and anti-inflammatory actions. © 2013 Asian Network for Scientific Information.

Background: Chronic exposure to high level of inorganic arsenic in drinking water has been associated with Type 2 Diabetes (T2D). Most research has been ecological in nature and has focused on high levels of arsenic exposure with few studies directly measuring arsenic levels in drinking water as an index of arsenic exposure. The effect of low to moderate levels of arsenic exposure on diabetes risk is largely unknown thus our study is adding further knowledge over previous works. Methods: This cross sectional study was conducted in 1004 consenting women and men from 1682 eligible participants yielding a participation rate of 60%. These participants are aged >30 years and were living in Bangladesh and had continuously consumed arsenic-contaminated drinking water for at least 6 months. T2D cases were diagnosed using glucometer following the new diagnostic criteria (Fasting Blood Glucose > 126 mg/dl) from the WHO guideline (WHO 2006), or a self-reported physician diagnosis of type 2 diabetes. Association between T2D and chronic arsenic exposure was estimated by multiple logistic regression with adjustment for age, sex, education, Body Mass Index (BMI) and family history of T2D. Results: A total of 1004 individuals participated in the study. The prevalence of T2D was 9% (95% CI 7-11%). After adjustment for diabetes risk factors, an increased risk of type 2 diabetes was observed for arsenic exposure over 50 μg/L with those in the highest category having almost double the risk of type 2 diabetes (OR=1.9 ; 95% CI 1.1-3.5). For most levels of arsenic exposure, the risk estimates are higher with longer exposure; a doseresponse pattern was also observed. Conclusions: These findings suggest an association between chronic arsenic exposure through drinking water and T2D. Risks are generally higher with longer duration of arsenic exposure. The risk of T2D is highest among those who were exposed to the highest concentration of arsenic for more than 10 years. © 2012 Voutsadakis; licensee BioMed Central Ltd.

A simple, one-step novel solution process was developed for the synthesis of carbon-doped CuO (C-CuO) nanoribbons without the use of a catalyst, template, substrate, or costly instrumentation at room temperature. The precursor materials used were converted into C-CuO nanoribbons in ethanol (95%) at high concentrations (4.37 mg mL-1) as a colloidal solution with very high dispersion stability. The simplicity, reaction time, production cost, production yield, and environmental friendliness of this process make it suitable for the large-scale industrial production of C-CuO nanoribbons. The prepared nanoribbon is also separable and redispersible in other organic solvents. The dispersibility in multiple solvents highlights its versatility as a platform for depositing other nanomaterials on its surface in organic media to improve its additional properties as a candidate for other applications. Its three-dimensional surface morphology was characterized, which suggested that the prepared C-CuO nanoribbon was highly porous. Free-standing C-CuO nanoribbon films were also prepared using a simple process. The prepared film of porous C-CuO nanoribbon exhibited excellent light absorption ability in the range from visible to near-IR light with higher intensity. The superior light absorption properties of the C-CuO nanoribbons were utilized in a photocatalyst to decompose an organic dye in visible light. The degradation of the organic dye (96.64%), recycling performance (93.94%), number of cycles (24), and degradation time (120 min) highlight its potential as a very good photocatalyst. © 2016 The Royal Society of Chemistry.

Remote-sensing images taken from the Landsat Enhanced Thematic Mapper Plus (ETM+) sensor with a spatial resolution of 30 m were applied for mapping and inventory of mangrove forest areas in Sundarbans, on both sides of the border between Bangladesh and India. Three different classification methods - unsupervised classification with k-means clustering, supervised classification using the maximum likelihood decision rule, and band-ratio supervised classification - were tested and compared in terms of the top of the atmosphere reflectance images. Spectral signature and principal component analyses were applied to select the appropriate band combinations prior to the band ratio-supervised classification. Our results show that the band ratio method is superior to the unsupervised or supervised classification methods considering the visual inspection, producer's and user's accuracy, as well as the overall accuracy of the all the classes in the image. The best discrimination of mangrove/nonmangrove boundary can be achieved when the combinations of B4/B2 (band 4/band 2), B5/B7, and B7/B4 are employed from the ETM+ bands. © 2013 Copyright Taylor and Francis Group, LLC.

Objective: To study the phytochemical and biological properties (antioxidant, anthelmintic and thrombolytic) of methanolic extracts of Enhydra fluctuans Lour., a plant belonging to the Asteraceae family. Methods: The phytochemical evaluation was carried out by qualitative analysis. In vitro antioxidant activity of extract was studied using free radical scavenging assay, ability of reduction, total phenol and total flavonoid contents determination assays. The anthelmintic activity was determined using paralysis and death time of Pheretima posthuma (earthworm) and thrombolytic activity by clot disruption assay. Results: The phytochemical evaluation showed significant presence of flavonoids, triterpenes, carbohydrate, reducing sugars, saponins, phenols, diterpenes, protein and tannin. The antioxidant activity was found significant [IC50=(135.20±0.56) μg/mL] as compared to ascorbic acid [(130.00±0.76) μg/mL]. The reducing power was increased with concentration. Total phenol and total flavonoid contents were (153.08±0.38) mg/mL and (172.04±0.56) mg/mL respectively. The paralysis and death time of earthworms for different concentrations of extract were determined and compared with albendazole. The results showed that 10 mg/mL of the crude extract had similar effect with albendazole. Additionally, the crude extract showed a concentration depended relationship with its anthelmintic property. The clot lysis activity of crude extract was compared to the standard streptokinase's clot lysis (40.13%) activity and found significant (31%). Conclusions: The study proves that the crude methanolic extract of Enhydra fluctuans Lour. has significant antioxidant, anthelmintic and thrombolytic activity containing wide range of phytochemicals. © 2014 by the Asian Pacific Journal of Tropical Biomedicine.
