We determined the correlation between a pesticide exposure, physical health and susceptibility toward tuberculosis along with hematological indices and liver enzymes’ alterations in sprayers exposed to pesticides. Molecular detection of Mycobacterium tuberculosis and Mycobacterium bovis was detected by targeting histone-like protein (hupB) gene. The WBC (white blood cells) and RBC (red blood cells) levels of male sprayers and non-sprayers were significantly different (P<0.05). In female spray workers, the WBC and neutrophils levels were significantly different as compared with non-sprayers. Overall, in both male and female pesticide-exposed sprayers, mean values of alanine amino transferase and aspartate amino transferase were higher as compared with unexposed workers. M. Tuberculosis were detected in 15% male sprayers and 36% female sprayers while, M. bovis was detected in 5% male sprayers and 10% female sprayers. A χ2-test indicated that there existed a significant different (P<0.05) between positive and negative M. tuberculosis and M. bovis in both male/female spray workers out of total. The susceptibility of pesticide-exposed sprayers to tuberculosis and alterations in hematology and liver enzymes is crucial for health. Toxic effects of pesticides may lead to a weak immune system and increased tuberculosis susceptibility.Journal of Exposure Science and Environmental Epidemiology advance online publication, 1 February 2017; doi:10.1038/jes.2016.88. © 2017 Nature America, Inc., part of Springer Nature.

The density and sound velocity for pure alcohols (methanol, ethanol, iso-propanol and n-butanol) and molal solutions of nitroimidazoles (metronidazole (MNZ) and dimetridazole (DMZ) have been measured at different temperatures (293.15–313.15 K). Different volumetric and acoustical parameters like apparent molar volume (Vϕ), partial molar volume (V˚ϕ), apparent molar isentropic compressibility (Kϕ), partial molar isentropic compressibility (K˚ϕ), hydration number (nH), acoustic impedance (Z) and intermolecular free length (Lf) of antibiotic solutions were calculated from the experimental values of density and sound velocity. The derived values have been used to explore the solute–solute and solute–solvent interactions. The Vϕ values are positive and Kϕ values are negative in both antibiotics, indicative of strong solute–solvent interactions and closely packed structure of antibiotics in alcohols. The decreasing trend of Lf with increasing antibiotic concentration shows the presence of strong intermolecular interactions in solutions. © 2016 Elsevier Ltd

Selenium is an essential trace element for humans and animals, and selenium deficiency is associated with several disease conditions such as immune impairment. Free radicals are produced in the body as a result of many biochemical processes in the body. All aerobic organisms possess antioxidant defense system to combat oxidative stress. Selenium is an important constituent of antioxidant enzymes, especially, glutathione peroxidase and some other selenoproteins that participate in various physiological activities and protects the cell against the deleterious effects of free radicals by modulating the cell response. However, their exact role is still unknown. Moreover, many human diseases are related to the cell cycle regulation. Selenium intakes, greater than the recommended daily allowance (RDA), appear to protect against certain types of cancers by finding its role in regulation of cell proliferation and apoptosis. The role of selenium has been explored in normal thyroid functioning, enhancing immune function, carcinogenesis, cardiovascular diseases, in the prevention of pre-eclampsia, diabetes mellitus and male reproduction etc. This article reviews introductory aspects of selenium as an essential micronutrient, different sources of selenium, Pharmacokinetics and its role in various pathologies and aims to provide an update on selenium profile.

Bark extract of Pinus pinaster has a long history of ethnomedicinal use and is available commercially as herbal dietary supplement with proprietary name pycnogenol. It is used as a food supplement to overcome many degenerative disorders. Rohdewald (2002) wrote the first comprehensive review of extract highlighting its antioxidative nature and its role in different diseases. Later, Watson (2003) and Gulati (2005) in their reviews about cardiovascular health, described the extract as a best neutraceutical agent in this regard. The objective of this paper is to review the current research on this extract in terms of extraction methods, its pharmacological, toxicological and nutraceutical effects and clinical studies. Web sites of Google Scholar, Pubmed and Medline were searched for articles written in English and published in peer-reviewed journals from 2006 to 2009 and sixty-nine research articles were extracted. Of these, two are about extraction advancement and analysis while the rest relate to its clinical, biological and nutraceutical aspects. © 2010 Elsevier Ireland Ltd. All rights reserved.

This paper is devoted to studying two interesting issues of a black hole with string cloud background. Firstly, we investigate null geodesics and find unstable orbital motion of particles. Secondly, we calculate deflection angle in strong field limit. We then find positions, magnifications, and observables of relativistic images for supermassive black hole at the galactic center. We conclude that string parameter highly affects the lensing process and results turn out to be quite different from the Schwarzschild black hole. © 2015 M. Sharif and Sehrish Iftikhar.

This work is a contribution towards the graphical display of 2D data when they are convex, monotone and positive. A piecewise rational function in a cubic/cubic form is proposed, which, in each interval, involves four free parameters in its construction. These four free parameters have a direct geometric interpretation, making their use straightforward. Illustrations of their effect on the shape of the rational function are given. Two of these free parameters are constrained to preserve the shape of convex, monotone and positive data, while the other two parameters are utilized for the modification of positive, monotone and convex curves to obtain a visually pleasing curve. The problem of shape preservation of data lying above a line is also discussed. The method that is presented applies equally well to data or data with derivatives. The developed scheme is computationally economical and pleasing. The error of rational interpolating function is also derived when the arbitrary function being interpolated is C3 in an interpolating interval. The order of approximation is O(hi 3). © 2012 Copyright Taylor and Francis Group, LLC.

This study describes the removal of Everdirect Orange-3GL and Direct Blue-67 by low cost rice milling waste in a batch mode. The effect of various process parameters like solution pH, particle size, biosorbent dose, initial dyes concentration, contact time and temperature on the removal of anionic dyes was investigated. Maximum biosorption capacity of rice milling waste was observed at pH 1 and 3 for Everdirect Orange-3GL and Direct Blue-67, respectively. The results showed that the biosorption capacity of rice milling waste decreased with increase in biosorbent dose and increased with increase in initial dyes concentration and temperature. A maximum biosorption capacity of 31.44 and 52.63 mg/g was observed for Everdirect Orange- 3GL and Direct Blue-67, respectively. Analysis of equilibrium data was done by commonly used isotherms. The experimental data followed the Langmuir, Freundlich and Temkin isotherm models very well. Adsorption data of both dyes was better described by the pseudo-secondorder kinetic model. Thermodynamic study revealed that the process was feasible and spontaneous at higher temperatures. Positive value of ΔH° (13.31 and 40.64 kJ/mol) showed that the process was endothermic in nature. FT-IR spectrum was also taken to investigate the functional groups involved in the biosorption of anionic dyes. The results suggested the applicability of rice milling waste in industrial processes for remediation of industrial effluents. © 2012 Desalination Publications. All rights reserved.

A Bézier like C1 rational quadratic trigonometric polynomial spline is developed. It defines two shape parameters in each subinterval. The approximation and geometric properties are investigated. The curvature continuity is established. The developed rational quadratic trigonometric polynomial spline is extended to C1 piecewise rational bi-quadratic function with four shape parameters in each rectangular patch. Data dependent constraints are developed on the shape parameters in the description of piecewise rational quadratic and bi-quadratic trigonometric polynomial spline for shape preservation of curve and regular surface data. The developed shape preserving schemes provide tangent continuity in quadratic form and does not restrict interval length, derivatives or data. © 2013 Production and hosting by Elsevier B.V. on behalf of Faculty of Computers and Information, Cairo University.

In this research study, the biosorption of Synolon red 3HF and Synolon black HWF-FS dyes onto novel biomasses mustard oil cake and linseed oil cake, respectively, was investigated in the batch mode using different process parameters like pH, particle size, biosorbent dose, initial dye concentration, contact time, and temperature. Maximum biosorption capacity was observed at pH 1 for Synolon red 3HF onto mustard oil cake and pH 2 for Synolon black HWF-FS onto linseed oil cake. The biosorption capacity was efficient at the smallest particle size of biosorbent. The amount of dye sorbed (mg/g) decreased with the decrease in biosorbent dose and increased with increase in initial dye concentration and temperature. The Freundlich isotherm model was best fitted to experimental data. The biosorption followed the pseudo-second-order kinetic model suggesting a chemisorption mechanism. An increase of biosorption capacity with temperature shows an endothermic nature of the process. In this research, the influence of electrolytes, heavy metals, and surfactants on the removal of dyes was also examined. © 2015 Balaban Desalination Publications. All rights reserved.

In laboratory study, the entomopathogenic nematodes, Steinernema carpocapsae (Sc) and Heterorhabditis bacteriophora (Hb) alone and in combination with the insecticide, imidacloprid were evaluated against workers and nymphs of Reticulitermes flavipes (Isoptera: Rhinotermitidae). The degree of interaction varied between the two nematode species. Results revealed that different concentrations, nematode species, exposure time and interaction between entomogenous nematodes and insecticides affected termite mortality in bioassay. It was found that nematodes species Hb and Sc alone had no significant effect on termite mortality but there was synergism between imidacloprid and nematodes species that caused more than 50% mortality in most treatments within all three colonies tested. Further study is warranted on this aspect of termite research so that this synergism between nematodes and insecticides can be applied in the field to control termite colonies and as a substitute for chemical control.
