Protective effect of Acampe praemorsa (Roxb.) Blatt. & McCann against oxidative stress

The current study was carried to make available phytochemical information and evaluation of antioxidant activity of Acampe praemorsa (Roxb.) Blatt. & McCann. The phytochemical analysis was carried out using procedures and quantified phenolic and alkaloid contents. The antioxidant activity was evaluated by in-vitro and in-vivo studies. The In-vitro antioxidant activity was carried on free radicals such as superoxide, hydroxyl DPPH, hydrogen peroxide, evaluation of reducing power. In-vivo study was carried on albino Wistar rats with different doses of extracts. The results provide that, A. praemorsa extracts have diversified phytochemicals in extracts like steroids, alkaloids, phenolics, glycosides, oils, quinones, tannins etc. The hydroalcoholic extract has more phenolic (26.80±0.51) and alkaloid (20.59±0.22) contents. The antioxidant activity results provide information that the extracts possess concentration dependent activity on tested free radicals. The hydroalcoholic extract has more protective nature against superoxide, DPPH, H2O2 free radicals and reducing power but ethyl acetate extract has more potential against hydroxyl free radical than hydroalcoholic extract. The extracts were found to be safe on toxic studies and In-vivo study results and they play significant role in controlling the oxidative enzymes such as catalase, superoxide dismutase, lipid peroxidation (malonaldehyde) in the body. Thus, it was determined that A. praemorsa have potential bioactive compounds and antioxidant activity

Two Efficient outsourced ABS (OABS) Schemes Denoted By OABS-I And OABS-II To Build An Efficient outsourced Verifying Protocol

Attribute-based signature (ABS) facilitates revelry to mark a message with fine-grained access control over make out information. Particularly, in an ABS system, users get hold of their attribute private keys from an attribute authority, with which they can presently sign messages for any predicate fulfilled by their attributes. We first advise and formalize a new concept called Outsourced ABS, i.e., OABS, in which the computational overhead at user side is really concentrated through outsourcing concentrated computations to an untrusted signing-cloud service provider (S-CSP). In addition, we be relevant this novel paradigm to existing ABS schemes to decrease the difficulty

Splenectomy for diagnosis of lymphomas: A case series

Splenomegaly can be caused by various etiologies such as infections, congestion/ portal hypertension, auto-immune diseases, infiltrative diseases and malignancy. It requires extensive work-up of hematological, radiological and sometimes bone marrow studies to arrive at definitive diagnosis. However, in 3-36% of cases, cause of splenomegaly remains unknown despite extensive work up; among which lymphomas (16-44%) are an important cause. Hence splenectomy and pathological examination of the spleen might be the only option in this sub-set of patients to confirm the diagnosis. Here is a series of four cases of splenomegaly of unknown etiology presented to us over a period of 3 years who underwent laparoscopic splenectomy for diagnostic purpose. All these cases were diagnosed as Non-Hodgkin's lymphoma. Thrombocytopenia, anaemia and symptoms due to mass effect that these patients had prior to surgery were reversed. All patients were started on chemotherapy with-in 4 weeks of surgery

Different atmospheric moisture divergence responses to extreme and moderate El Niños

On seasonal and inter-annual time scales, vertically integrated moisture divergence provides a useful measure of the tropical atmospheric hydrological cycle. It reflects the combined dynamical and thermodynamical effects, and is not subject to the limitations that afflict observations of evaporation minus precipitation. An empirical orthogonal function (EOF) analysis of the tropical Pacific moisture divergence fields calculated from the ERA-Interim reanalysis reveals the dominant effects of the El Niño-Southern Oscillation (ENSO) on inter-annual time scales. Two EOFs are necessary to capture the ENSO signature, and regression relationships between their Principal Components and indices of equatorial Pacific sea surface temperature (SST) demonstrate that the transition from strong La Niña through to extreme El Niño events is not a linear one. The largest deviation from linearity is for the strongest El Niños, and we interpret that this arises at least partly because the EOF analysis cannot easily separate different patterns of responses that are not orthogonal to each other. To overcome the orthogonality constraints, a self-organizing map (SOM) analysis of the same moisture divergence fields was performed. The SOM analysis captures the range of responses to ENSO, including the distinction between the moderate and strong El Niños identified by the EOF analysis. The work demonstrates the potential for the application of SOM to large scale climatic analysis, by virtue of its easier interpretation, relaxation of orthogonality constraints and its versatility for serving as an alternative classification method. Both the EOF and SOM analyses suggest a classification of “moderate” and “extreme” El Niños by their differences in the magnitudes of the hydrological cycle responses, spatial patterns and evolutionary paths. Classification from the moisture divergence point of view shows consistency with results based on other physical variables such as SST

Identifying causes of Western Pacific ITCZ drift in ECMWF System 4 hindcasts

The development of systematic biases in climate models used in operational seasonal forecasting adversely affects the quality of forecasts they produce. In this study, we examine the initial evolution of systematic biases in the ECMWF System 4 forecast model, and isolate aspects of the model simulations that lead to the development of these biases. We focus on the tendency of the simulated intertropical convergence zone in the western equatorial Pacific to drift northwards by between 0.5° and 3° of latitude depending on season. Comparing observations with both fully coupled atmosphere–ocean hindcasts and atmosphere-only hindcasts (driven by observed sea-surface temperatures), we show that the northward drift is caused by a cooling of the sea-surface temperature on the Equator. The cooling is associated with anomalous easterly wind stress and excessive evaporation during the first twenty days of hindcast, both of which occur whether air-sea interactions are permitted or not. The easterly wind bias develops immediately after initialisation throughout the lower troposphere; a westerly bias develops in the upper troposphere after about ten days of hindcast. At this point, the baroclinic structure of the wind bias suggests coupling with errors in convective heating, although the initial wind bias is barotropic in structure and appears to have an alternative origin

Microwave-Assisted Synthesis of Titania Nanocubes, Nanospheres and Nanorods for Photocatalytic Dye Degradation

TiO2nanostructures with fascinating morphologies like cubes, spheres, and rods were synthesized by a simple microwave irradiation technique. Tuning of different morphologies was achieved by changing the pH and the nature of the medium or the precipitating agent. As-synthesized titania nanostructures were characterized by X-ray diffraction (XRD), UV–visible spectroscopy, infrared spectroscopy (IR), BET surface area, photoluminescence (PL), scanning electron microscopy (SEM) and transmission electron microscopy (TEM), and atomic force microscopy (AFM) techniques. Photocatalytic dye degradation studies were conducted using methylene blue under ultraviolet light irradiation. Dye degradation ability for nanocubes was found to be superior to the spheres and the rods and can be attributed to the observed high surface area of nanocubes. As-synthesized titania nanostructures have shown higher photocatalytic activity than the commercial photocatalyst Degussa P25 TiO2

Polymorphic Signature of the Anti-inflammatory Activity of 2,2′- {[1,2-Phenylenebis(methylene)]bis(sulfanediyl)}bis(4,6- dimethylnicotinonitrile)

Weak noncovalent interactions are the basic forces in crystal engineering. Polymorphism in flexible molecules is very common, leading to the development of the crystals of same organic compounds with different medicinal and material properties. Crystallization of 2,2′- {[1,2-phenylenebis(methylene)]bis(sulfanediyl)}bis(4,6-dimethylnicotinonitrile) by evaporation at room temperature from ethyl acetate and hexane and from methanol and ethyl acetate gave stable polymorphs 4a and 4b, respectively, while in acetic acid, it gave metastable polymorph 4c. The polymorphic behavior of the compound has been visualized through singlecrystal X-ray and Hirshfeld analysis. These polymorphs are tested for anti-inflammatory activity via the complete Freund’s adjuvant-induced rat paw model, and compounds have exhibited moderate activities. Studies of docking in the catalytic site of cyclooxygenase-2 were used to identify potential anti-inflammatory lead compounds. These results suggest that the supramolecular aggregate structure, which is formed in solution, influences the solid state structure and the biological activity obtained upon crystallization
