Objective:To compare the effectiveness and safety of Clarithromycin and co-amoxyclav for the treatment of mild to moderate cases of acute exacerbation of chronic otitis media (AECOM).Materials and methods:Adult patients diagnosed with AECOM were screened and patients fulfilling the inclusion criteria were randomized to receive either Clarithromycin (500 mg) twice daily or co-amoxyclav (625 mg) thrice daily orally for 7 days. The primary outcome of this randomized, open-labeled, phase IV clinical trial was clinical success rate at day 14 visit and the secondary outcome was incidence of adverse events (AES). Fifty patients were enrolled : 25 in the Clarithromycin group and 25 in the co-amoxyclav group.Results :  The clinical success rates were 92.7 % in the Clarithromycin group versus 90.2% in the co-amoxyclav group. These rates are comparable, but no statistically significant difference was observed between the groups.Conclusion:The results of this randomized, open-labeled phase IV clinical trial showed that a 7-day course of Clarithromycin is therapeutically comparable to co-amoxyclav in terms of both clinical effectiveness and safety for the treatment of patients with AECOM

Adsorption of As (III) and As (V) from aqueous solution by modified Cassia fistula (golden shower) biochar

Abstract The biosorption of two Arsenic (As) species [As (III) and As (V)] from aqueous solution onto activated biochar derived from Cassia fistula, belonging to Fabaceae family was studied. SEM/EDX characterization of the adsorbent showed an irregular, porous, and heterogeneous surface morphology with calcium and iron available for As binding. FTIR also showed the presence of groups responsible for As adsorption. Batch adsorption experiments were conducted to determine the optimum conditions for As adsorption to the biomass with optimum adsorbent dose, ambient temperature, initial concentration of As, pH, and stirring rate. Under optimized conditions, the maximum removal percentage was 78.1% [uptake capacity (q e) = 0.78 mg/g] for As (III) and 84.8% [uptake capacity (q e) = 0.42 mg/g] for As (V). The Freundlich isotherm model, characteristic of multilayer binding, fit the data best with R 2 values of 0.92 for As (III) and 0.96 for As (V). Fitting of the data to the Dubinin–Radushkevich model indicated physisorption, while the kinetics study suggested a pseudo-second-order reaction. Thermodynamic parameters indicated adsorption was spontaneous. In aqueous solutions, phosphate hindered As removal more than the any other ions. Regeneration studies showed a 23.0% and 21.1% recovery for arsenite and arsenate, respectively, indicating limited leaching under both acidic and alkaline conditions. The absorptive capacity of C. fistula biomass for arsenic removal was compared with a number of other reported biosorbents and was found to be considerably efficient

Not AvailableThe effect of pre-harvest application of Methyl Jasmonate (MeJA) on berry quality, flavonoid content and antioxidant capacity in grapes (Vitis vinifera L.) cv. Pusa Navrang were studied under subtropical conditions of New Delhi. Different doses of MeJA (0, 5, 10, 15 mM) were applied at three different dates. There were no significant differences were recorded for bunch and berry weight. Grapes treated with MeJA had slightly higher soluble solid content, lower titratable acids than untreated berries. Methyl jasmonate significantly enhanced the content of total monomeric anthocyanins, total phenolics, flavonoids and the antioxidant capacities in the berries. These were found significantly different for dose of methyl jasmonate and time of application. In general, when MeJA(10 mM) applied at veraison stage was found most effective for improving the berry bioactive compounds and had significantly higher total monomeric anthocyanin (1434.43 C3GE mg/kg fresh berry weight), total phenolic content (504.58 mg/100 g),total flavonoid content and antioxidant activity measured in terms of DPPH.Not Availabl

Covalency-driven structural instability and spin-phonon coupling in barium cobalt oxychloride

Our combined experimental and theoretical study reveals unusually large cobalt-oxygen covalency in CoO 4 tetrahedral unit of a barium cobalt oxychloride compound. This drives significant charge redistribution, resulting into large hole density on tetrahedral oxygens, which effectively behave as “positively charged” anions. These positively charged oxygens form local dipoles with dopant chloride anions, situated in the same atomic plane, which gets manifested in associated structural distortions. The spatial freezing of these local dipoles below certain temperature is found to produce concomitant effects on dielectric and magnetic responses, coupled via exchange-striction driven spin-phonon interaction. Our study should form the basis for designing new functional oxide materials using the concept of covalency-driven charge redistribution

A review on deformation structures of different terranes in the Precambrian Aravalli-Delhi Mobile Belt (ADMB), NW India:Tectonic implications and global correlation

The Aravalli-Delhi Mobile Belt (ADMB) in the northwestern part of the Indian Shield represents the final stage of a complex tectonic evolution witnessed by the recognition of three distinct orogenies that have resulted in northwestward accretion of the terranes belonging to Archaean to Neoproterozoic ages. In this contribution, a review of the deformation structures of different terranes is discussed with their tectonic implications and global correlation with other supercontinent assemblies. In the west, the NE-SW trending Neoproterozoic South Delhi terrane is marked by coaxial folding between DF1 and DF2 along the NE-SW axis and cross folded by DF3 folds in the NW-SE axis. Several meso- to large-scale DF2 thrusts and DF4 fractures occur in the belt, that acted as channels for the exhumation of granulite and basement gneisses. Excess shortening led to orogen parallel extension and lateral escape of the material that reactivated the DF2 thrusts as strike-slip faults. Based on the ages of syn-DF1 granite gneisses, DF4 fractures, the South Delhi orogeny has been constrained between 0.87 and 0.6 Ga. The Paleoproterozoic North Delhi Terrane is marked by a coaxial folding between NF1 and NF2 folds and later cross-folded by NW-SE trending NF3 folds, producing dome- and basin-structures. Age of syntectonic granite and late-stage metamorphism constrain the north Delhi orogeny between 1.8 and 0.96 Ga. The Paleoproterozoic Aravalli Terrane is divided into a shallow-marine eastern and deeper marine western part by the Rakhabdev suture zone. The entire assemblage of terranes was folded by NE-SW isoclinal and recumbent AF1 folds which, with progressive deformation, were reoriented with a E-W axial trend. The AF2 is upright and NE-SW trending. The AF3 folds are E-W to NW-SE trending and have produced type 1 and type 2 interference patterns, with AF2 and AF1 respectively. Age of syn-AF1 migmatisation in the northern part and syn-AF3 granites in the south constrain the Aravalli orogeny between 1.7 and 0.96 Ga, coeval with the North Delhi orogeny. The granulite and charnockite were tectonically emplaced within the Sandmata Complex during the Aravalli orogeny. The Archean Bhilwara terrane, produced from the Bhilwara orogeny, marks the stabilisation of the crust in NW India by the intrusion of Berach and equivalent granites at 2.6 Ga. The terrane is divided into the Sandmata and Mangalwar complexes that consist of migmatite gneisses with slivers of greenstone. Several Neoarchean to Paleoproterozoic volcano-sedimentary schist belts were tectonically interlaced within the Mangalwar Complex. The migmatitic rocks of the terrane show flow folding in various directions while the schist belts are characterized by extremely appressed NE-SW trending reclined folds (BF1 and BF2), inverted BF2 folds, E-W open BF3 folds, and multiple strike-slip shear zones and thrusts. The ADMB exhibits a syntaxial bend in the eastern part attributed to indentation tectonics by Berach granite during syn-South Delhi orogeny. The Aravalli orogeny can be correlatable with Nuna orogeny, whereas the South Delhi orogeny can be correlated with the Pan-African orogeny that gave rise to Columbia and Gondwanaland Supercontinent assembly. The Grenville orogeny has experienced thermal rejuvenation in the Aravalli and Bhilwara terranes
