Research on the effects of Mobile phone radio frequency emissions on biological systems has been focused on noise and vibrations as auditory stressors. This study investigated the potential effects of exposure to mobile phone electromagnetic field radiation, ringtone and vibration on anxiety-like behaviour and oxidative stress biomarkers in albino wistar rats. Twenty five male wistar rats were randomly divided into five groups of 5 animals each: group I: exposed to mobile phone in switched off mode (control), group II: exposed to mobile phone in silent mode, group III: exposed to mobile phone in vibration mode, group IV: exposed to mobile phone in ringtone mode, group V: exposed to mobile phone in vibration and ringtone mode. The animals in group II to V were exposed to 10 min call (30 missed calls for 20 s each) per day for 4 weeks. Neurobehavioural studies for assessing anxiety were carried out 24 h after the last exposure and the animals were sacrificed. Brain samples were collected for biochemical evaluation immediately. Results obtained showed a significant decrease (P < 0.05) in open arm duration in all the experimental groups when compared to the control. A significant decrease (P < 0.05) was also observed in catalase activity in group IV and V when compared to the control. In conclusion, the results of the present study indicates that 4 weeks exposure to electromagnetic radiation, vibration, ringtone or both produced a significant effect on anxiety-like behavior and oxidative stress in young wistar rats. © 2015 Springer Science+Business Media New York Source

Discussions about global health issues related to drugs usually concentrate on affordability and availability, with limited consideration of other precipitating factors associated with distribution inequalities and efficacy in low-income countries. Inappropriate prescribing has a significant public health impact ranging from ineffective treatment of disease, drug resistance and potential harm to patients. We report on the problems associated with unsuitable prescribing of medication in an African setting. © The Author(s) 2013. Source

The study was conducted to screen for in vitro antibacterial activity of crude ethanol, acetone and aqueous seeds extract of Garcinia kola at different treatment regimes against some selected clinical bacterial isolates comprising of Gram positive and negative organisms namely; Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa and the major chemical groups responsible for the activity were determined. The agar well diffusion method was employed to determine the inhibitory effects of the seeds extract on the test microorganisms. The minimum inhibitory concentration exerted by the extracts against the bacterial isolates ranged between 3.125 and 25 mg/ml. The zones of inhibition exhibited by the extracts against the tested bacterial isolates ranged between 4.0 and 10.5 mm. The crude ethanol extract was found to exhibit more significant (P<0.01) inhibitory action against all the bacterial isolates at the various treatment regime. Also, compared to crude acetone and aqueous extracts, it was also notably found to exhibit significant (P<0.05) effects against the bacterial isolates. The preliminary phytochemical test revealed the presence of flavonoids, tannins, saponins, sterols and terpenes as the major chemical groups in the plant extracts. The results of this study revealed that the in vitro antibacterial activity exhibited by the seeds extract may be attributed to the presence of these phytochemical compounds. © 2012 Academic Journals.

Corrosion has been chronic problem to industries and has increased cost of production. Lignin is the second most natural organic polymer on the earth and it can be obtained from the wastes of wood pulping processing in the form of black liquor. The inhibition efficiency of lignin on the corrosion of mild steel in 1 M HCl have been evaluated by conventional weight loss method, and surface analysis using 500-5000 mg/L (w/v) inhibitor concentration in temperature range of 303-343 K. Maximum inhibition efficiency of 92.39 % was obtained with optimum inhibitor concentration of 4000 mg/L at 303 K. The activation and free energies for the inhibition reactions support the mechanism of physical adsorption. The adsorption of lignin extract on mild steel surface is endothermic, spontaneous and consistent with the Langmuir adsorption isotherm at all studied temperatures. FT-IR and SEM analyses confirmed that the surface of mild steel was affected by the adsorption of lignin onto the surface to form ferric-lignin compounds. Source

Sub-bituminous coals of Ramagundam coalfield have been studied to know their petrographic and chemical composition. Based on the petrographic characters, an attempt has been made to understand their depositional environment. These coals are characterized by low to medium moisture and volatile matter contents. Inertinite is the dominant maceral group followed by vitrinite and liptinite and the coal contains significantly elevated inorganic content. The study reveals that they have originated from forest swamps under a mildly oxic to anoxic environment with conditions favorable for tissue preservation. © Taylor & Francis Group, LLC. Source
