    Background: Bellamya bengalensis, an edible bivalve mollusc is traditionally used in the treatment of joint pain, bone fracture, jaundice and eye infections. Present study was designed to find out the most potent analgesic fractions derived from the body mass of Bellamya bengalensis.Methods: The test specimen was collected, identified and fractionated with solvent medium like, phosphate buffer saline (PB), ethyl acetate (EB), methanol (MB) and chloroform (CB). Protein concentration of each fraction was determined. The antinociceptive activities were measured either by thermal models like, hot plate and tail immersion (central analgesic action) or by chemical model like acetic acid induced writhing (peripheral analgesic action) in mice. Diclofenac sodium was used as analgesic standard.Results: Significant peripheral and central analgesic activity showed by phosphate buffer saline fraction at 100mg/kg, even better than diclofenac standard at 10mg/kg. In hot plate and tail immersion tests, phosphate buffer saline showed the highest activity followed by methanol, chloroform and ethyl acetate fraction respectively. However, in case of peripheral analgesic experiment, phosphate buffer fraction exhibited maximum writhing inhibitory properties and that was followed by chloroform, methanol and ethyl acetate fraction respectively.Conclusions: Phosphate buffer saline fraction of Bellamya bengalensis showed maximum potential central and peripheral analgesic activity than any other fractions

    Background: Inflammation is complex biological response of body tissues to foreign particles or pathogens. However, adverse effects of anti-inflammatory drugs, necessitate the search for a novel compound from herbal origin. Beta vulgaris rubra or red beetroot, a vegetable plant, is known to possess various beneficial effects. Present study aimed to evaluate the anti inflammatory effect of beet roots in animal models.Methods: Carrageenan-induced and Complete Freund’s adjuvant-induced rat paw edema model were used to assess the acute and chronic anti- inflammatory potential of the Beetroot as compared to standard drug, Diclofenac Sodium.Results: Oral administration of Beetroot extract showed carrageenan-induced rat paw edema inhibition by 26.9%, 34.6% and 50% for beetroot 100mg/Kg, 200mg/Kg and 400mg/Kg, respectively, at the end of four hours. In vivo results noted that percentage inhibition of paw volume and ankle diameter of the Complete Freund’s adjuvant-induced rats were significantly higher for the groups consuming 100 and 200mg/Kg Beetroot extracts. Paw volume of the rats in these two groups reduced by 35% and 30% respectively as compared to the control.Conclusions: Thus, beetroot was found to possess anti-inflammatory property in animals. Further investigations are essential to validate the bioactive components responsible for this property

    Capparis decidua belongs to family Capparidaceae in wastelands of India. The study aim was to determine the role of C. decidua fruits on the free fatty acids (FFA) profile in fat-rich diet (FRD) dyslipidemic rats. The methanolic extract of edible fruit of C. decidua (CD) was given orally to obese dyslipidemic rats at the dose of 125 mg/kg and 250 mg/kg for consecutive 28 days. CD treatment in FRD rats significantly restricts the body weight gains. Blood lipid profile was altered dose dependently and significantly after 4-week treatment with CD to FRD. rats. It significantly (p<0.05) enhanced serum FFA especially, g-linolinate, a-linolinate, arachidonate, ecosapentaenoate, docosapentaenoate and docosahexaenoate. Moreover, w3-PUFA content was also enhanced (50.3% and 78.8%) in the serum of CD treated animals, whereas MUFA was lowered (31.1% and 40%). Therefore, Capparis decidua fruit has a promising role on dyslipidemia and obesity and has the capabilities to regulate beneficial free fatty acids.

    Introducción: Sonneratia apetala Buch-Ham es un verdadero habitante de los manglares en Sunderban indio y se utiliza en la medicina popular para los trastornos digestivos. Método: El extracto hidrometanólico (20:80) de hojas de Sonneratia apetala (SA) se estandarizó químicamente por HPTLC y se evaluó por sus propiedades antirradicales y gastroprotectoras. Se determinaron los fenólicos y flavonoides presentes en SA y se evaluaron las actividades antirradicales mediante métodos in vitro como, DPPH (1,1-difenil-2-picrilhidrazilo), óxidos nítricos, superóxidos, hidroxilo y ABTS (2,2 / -azino-bis- Ácido 3-etilbenztiazolin-6-sulfónico). Además, se evaluó la eficacia gastroprotectora de SA en la ulceración oxidativa inducida por alcohol (50% v / v, 5 ml / kg) en ratas. Resultados: El SA químicamente estandarizado mostró presencia de compuestos polifenólicos. También mostró fuertes propiedades antirradicales. Las administraciones orales de SA (125 mg / kg y 250 mg / kg) protegieron significativamente la membrana mucosa gástrica del daño ulcerativo causado por el alcohol, similar al omeprazol (20 mg / kg) en ratas. Además, el tratamiento con SA redujo significativamente la elevación de los peróxidos de lípidos; mientras que aumentó la concentración de glutatión y catalasa en la mucosa gástrica con respecto a las ratas de control no tratadas inducidas por etanol. Conclusiones: Los resultados obtenidos de este estudio sugieren que la hoja de Sonneratia apetala tiene propiedades antioxidantes y tiene capacidad para proteger la lesión de la mucosa gástrica causada por la ingestión de alcohol.Introduction: Sonneratia apetala Buch-Ham is a true mangrove inhabitant in Indian Sunderban and it is used in folk medicine for digestive disorders. Method: Hydro-methanolic (20:80) extract of Sonneratia apetala leaves (SA) was chemically standardized by HPTLC and evaluated for its antiradical and gastro-protective properties. Phenolics and flavonoids present in SA were determined and antiradical activities were assessed by in vitro methods like, DPPH (1,1-diphenyl-2-picrylhydrazyl), nitric oxides, superoxides, hydroxyl and ABTS (2,2/ -azino-bis-3-ethyl benzthiazoline-6-sulphonic acid). Further, gastro-protective efficacy of SA was assessed in alcohol (50% v/v, 5 ml/kg) induced oxidative ulceration in rats. Results: Chemically standardized SA exhibited presence of polyphenolic compounds. It also showed strong antiradical properties. Oral administrations of SA (125 mg/kg and 250 mg/kg) significantly protected gastric mucosal membrane from ulcerative damage caused by alcohol, similar to Omeprazole (20 mg/kg) in rats. Moreover, SA treatment significantly reduced the elevation of lipid peroxides; while enhanced the concentration of glutathione and catalase in gastric mucosa in respect to ethanol induced untreated control rats. Conclusions The results obtained from this study suggest Sonneratia apetala leaf has antioxidant properties and has capabilities to protect gastric mucosal injury caused by alcohol ingestion.Project 537(sanc)/ST/P/S&T/5G-4/2009-11 of the Department of Science & Technology, Govt. of West Bengal, Indi

    Background Understanding the magnitude of cancer burden attributable to potentially modifiable risk factors is crucial for development of effective prevention and mitigation strategies. We analysed results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 to inform cancer control planning efforts globally. Methods The GBD 2019 comparative risk assessment framework was used to estimate cancer burden attributable to behavioural, environmental and occupational, and metabolic risk factors. A total of 82 risk-outcome pairs were included on the basis of the World Cancer Research Fund criteria. Estimated cancer deaths and disability-adjusted life-years (DALYs) in 2019 and change in these measures between 2010 and 2019 are presented. Findings Globally, in 2019, the risk factors included in this analysis accounted for 4.45 million (95% uncertainty interval 4.01-4.94) deaths and 105 million (95.0-116) DALYs for both sexes combined, representing 44.4% (41.3-48.4) of all cancer deaths and 42.0% (39.1-45.6) of all DALYs. There were 2.88 million (2.60-3.18) risk-attributable cancer deaths in males (50.6% [47.8-54.1] of all male cancer deaths) and 1.58 million (1.36-1.84) risk-attributable cancer deaths in females (36.3% [32.5-41.3] of all female cancer deaths). The leading risk factors at the most detailed level globally for risk-attributable cancer deaths and DALYs in 2019 for both sexes combined were smoking, followed by alcohol use and high BMI. Risk-attributable cancer burden varied by world region and Socio-demographic Index (SDI), with smoking, unsafe sex, and alcohol use being the three leading risk factors for risk-attributable cancer DALYs in low SDI locations in 2019, whereas DALYs in high SDI locations mirrored the top three global risk factor rankings. From 2010 to 2019, global risk-attributable cancer deaths increased by 20.4% (12.6-28.4) and DALYs by 16.8% (8.8-25.0), with the greatest percentage increase in metabolic risks (34.7% [27.9-42.8] and 33.3% [25.8-42.0]). Interpretation The leading risk factors contributing to global cancer burden in 2019 were behavioural, whereas metabolic risk factors saw the largest increases between 2010 and 2019. Reducing exposure to these modifiable risk factors would decrease cancer mortality and DALY rates worldwide, and policies should be tailored appropriately to local cancer risk factor burden.

    Search for heavy resonances decaying to two Higgs bosons in final states containing four b quarks

    Get PDF
    A search is presented for narrow heavy resonances X decaying into pairs of Higgs bosons (H) in proton-proton collisions collected by the CMS experiment at the LHC at root s = 8 TeV. The data correspond to an integrated luminosity of 19.7 fb(-1). The search considers HH resonances with masses between 1 and 3 TeV, having final states of two b quark pairs. Each Higgs boson is produced with large momentum, and the hadronization products of the pair of b quarks can usually be reconstructed as single large jets. The background from multijet and t (t) over bar events is significantly reduced by applying requirements related to the flavor of the jet, its mass, and its substructure. The signal would be identified as a peak on top of the dijet invariant mass spectrum of the remaining background events. No evidence is observed for such a signal. Upper limits obtained at 95 confidence level for the product of the production cross section and branching fraction sigma(gg -> X) B(X -> HH -> b (b) over barb (b) over bar) range from 10 to 1.5 fb for the mass of X from 1.15 to 2.0 TeV, significantly extending previous searches. For a warped extra dimension theory with amass scale Lambda(R) = 1 TeV, the data exclude radion scalar masses between 1.15 and 1.55 TeV
