A simple, accurate and rapid spectrophotometric method for the estimation of azithromycin has been developed by the acidic hydrolysis of the drug with sulfuric acid and monitoring the absorbance at 482nm. All variables affecting the... more
Tribolium flour beetles produce defensive compounds, including quinones, putatively aimed at deterring predators and inhibiting microbes. Here we examine how effective the defensive secretions of Tribolium confusum and T. castaneum are at... more
The genetic components responsible for qualitative and quantitative resistance of rice plants to three strains (CR4, CXO8, and CR6) of Xanthomonas oryzae pv. oryzae (Xoo) were investigated using a set of 315 recombinant inbred lines... more
A simple ultraviolet spectrophotometric method for the determination of simvastatin in methanol has been devised and compared with the existing pharmacopoeial RP-HPLC method for the estimation of the drug. Analytical parameters such as... more
Two ionic liquids (ILs), namely (S,S)-1-butyl-3-(2′-hydroxy-cyclohexyl)-3H-imidazol-1-ium tetrafluoroborate and (S,S)-1-butyl-3-(2′-acetyl-cyclohexyl)-3H-imidazol-1-ium tetrafluoroborate have been employed as stationary phases in... more
Aim Bats communicate by emitting social calls, and these often elicit reactions in conspecifics. Many such vocalizations are species-specific so that unambiguous signals can be transmitted and interpreted by conspecifics. In species-rich... more
The ability of natural selection to drive local adaptation has been appreciated ever since Darwin. Whether human impacts can impede the adaptive process has received less attention. We tested this hypothesis by quantifying natural... more
Validations of analytical methods are important for the generation of data for bioavailability, bioequivalence and pharmacokinetic studies. It is essential to use well defined and fully validated analytical methods to obtain reliable... more
A traditional focus of evolutionary paleoecology has been the reconstruction of the selective forces that have affected evolving lineages through time. If the history of those lineages is dominated by stasis and punctuation, however, this... more
