Objective: Pergularia daemia [Forsk] has been used from the long time in traditional medicine. The main objective of this work is to evaluate anti-rheumatic activity of leaf of Pergularia daemia [Forsk] Methods: Anti- arthritic activity of petroleum ether and methanol extracts of leaf of Pergularia daemia [Forsk] was evaluated by using Freund's complete adjuvant model. Results: Preliminary Phytochemical investigation of Petroleum ether extract of leaf of Pergularia daemia [Forsk] shows presence of steroids, terpenoids, sterols while methanolic extract of leaf of Pergularia daemia [Forsk] shows presence of alkaloids, glycosides, flavonoids, tannins and phenolic component. The petroleum ether and methanol extract of leaf of Pergularia daemia [300 mg/kg] shows an improvement in arthritis condition by reducing hind paw inflammation. Conclusion: The methanolic extract was found to be more potent than petroleum ether extract. The result indicates that the petroleum ether and methanol extract contain such phytochemical constituents which are responsible for analgesic and anti-rheumatic activity

In this paper, we present bounds on check symbols required for the codes capable to detect as well as correct the restricted bursts errors that are repeating themselves in a single sub-block. For these codes the whole code length is considered to be subdivided into a certain number of mutually exclusive sub-blocks of equal length

Bioactive components from Gynandropsis gynandra leaves for antinociceptive activity

Gynandropsis gynandra Linn. (Capparadiaceae) leaves are used in the treatment of pain traditionally. In order to evaluate its scientific validity, leaves were extracted successively to produce various extracts. These extracts were screened for antinociceptive activity using hot plate test and acetic acid-induced writhing test in mice at the dose of 100 mg/kg, intraperitoneally. Aqueous extract was found most active in both the tests. Further it was fractionated into four major fractions and were screened by the same tests at the dose of 25 mg/kg, i.p. Results showed that AQI fraction is most active and may responsible for the antinociceptive action. GC-MS analysis of AQI fraction showed that it is a mixture of benzene acetic acid ethyl ester, octaneoic acid, dodecanal, and cholest-4-en-26-al, 3-oxo-, cyclic 26-(ethylene acetate).Colegio de Farmacéuticos de la Provincia de Buenos Aire

Antiasthmatic activity of Nyctanthes arbortristis leaves

Nyctanthes arbortristis Linn. (Oleaceae) is one of the well known medicinal plants. It is commonly known as "Night Jasmine". As traditionally the plant is used in the treatment of asthma and cough it was our objective to study its antiasthmatic potential using suitable models. Various extracts of the plant were screened for antihistaminic activity by studying the effect of the extracts on clonidine and haloperidol-induced catalepsy in mice. Antiallergic effect was studied by checking effect of the extracts on milk-induced leukocytosis and eosinophilia. Mast cell stabilization by the extracts was studied in mice. Results showed that petroleum ether extract had better antihistaminic, antiallergic and mast cell stabilization property than other extracts. β-sitosterol was identified from the petroleum ether extract having antiasthmatic activity, so we can say that the antiasthmatic activity of N. arbortristis leaves is may be due to presence of β-sitosterol.Colegio de Farmacéuticos de la Provincia de Buenos Aire

Study of Structural and Electronic Properties of CsMgCl3 Compound

In this report, we have investigated the CsMgCl3 compound with the help of the WIEN2K software package. The structural and electronic properties are performed using the full potential augmented plane wave (FP-LAPW) method with the generalised gradient approximation (GGA) approximation as exchange correlation potentials. We used the Birch-Murnaghan equation (BME) to find the structural properties of the material. These include the lattice parameter, the bulk modulus, the first derivative of the bulk modulus, the minimum energy, and the volume. The structural properties match up with the experimental data. Electronic properties in terms of the band structure (BS) and total and partial density of state (T-DOS and P-DOS) profiles of CsMgCl3 using GGA potentials exhibit an indirect wide energy band gap of 5.35 eV. All these properties show that the CsMgCl3 compound is used as a perovskite in solar cells

Potentially toxic elemental contamination in Wainivesi River, Fiji impacted by gold - mining activities using chemometric tools and SOM analysis

Potentially toxic element (PTE) contamination in Wainivesi River, Fiji triggered by gold-mining activities is a major public health concern deserving attention. However, chemometric approaches and pattern recognition of PTEs in surface water and sediment are yet hardly studied in Pacific Island countries like Fijian urban River. In this study, twenty-four sediment and eight water sampling sites from the Wainivesi River, Fiji were explored to evaluate the spatial pattern, eco-environmental pollution, and source apportionment of PTEs. This analysis was done using an integrated approach of self-organizing map (SOM), principle component analysis (PCA), hierarchical cluster analysis (HCA), and indexical approaches. The PTE average concentration is decreasing in the order of Fe > Pb > Zn > Ni > Cr > Cu > Mn > Co > Cd for water and Fe > Zn > Pb > Mn > Cr > Ni > Cu > Co > Cd for sediment, respectively. Outcomes of eco-environmental indices including contamination and enrichment factors, and geo-accumulation index differed spatially indicated that majority of the sediment sites were highly polluted by Zn, Cd, and Ni. Cd and Ni contents can cause both ecological and human health risks. According to PCA, both mixed sources (geogenic and anthropogenic such as mine wastes discharge and farming activities) of PTEs for water and sediment were identified in the study area. The SOM analysis identified three spatial patterns, e.g., Cr–Co–Zn–Mn, Fe–Cd, and Ni–Pb–Cu in water and Zn–Cd–Cu–Mn, Cr–Ni and Fe, Co–Pb in sediment. Spatial distribution of entropy water quality index (EWQI) values depicted that northern and northwestern areas possess “poor” to “extremely poor” quality water. The entropy weights indicated Zn, Cd, and Cu as the major pollutants in deteriorating the water quality. This finding provides a baseline database with eco-environmental and health risk measures for the Wainivesi river contamination
