Objective: To establish the fingerprint profile of Wedelia chinensis using thin layer chromatography (TLC) and high performance thin layer chromatography (HPTLC) technique. Methods: TLC and HPTLC studies were carried out in two different solvent systems, which showed different Rf value. Results: TLC profiling of the extract confirm about the presence of various phytochemicals. HPTLC finger prin...

is also finite, since obviously such a form takes integral values at integral points. Let NF (m) denote the number of integral solutions to the Thue inequality above and consider the region RF = {(x, y) ∈ R2 : |F (x, y)| ≤ 1}. Then the dilation of RF by m1/d consists of all (x, y) ∈ R2 with |F (x, y)| ≤ m, so that one would expect mAF , where AF is the area of RF , to approximate NF (m). Indeed...

The visual system uses binocular disparity to discriminate the relative depth of objects in space. Because the striate cortex is the first site along the central visual pathways at which signals from the left and right eyes converge onto a single neuron, encoding of binocular disparity is thought to begin in this region. There are two possible mechanisms for encoding binocular disparity through...

BACKGROUND With a large-scale electronic health record repository, it is feasible to build a customized patient outcome prediction model specifically for a given patient. This approach involves identifying past patients who are similar to the present patient and using their data to train a personalized predictive model. Our previous work investigated a cosine-similarity patient similarity metri...

Introduction: Radiochemical purity (RCP) is a routine quality control test carried out at nuclear medicine to determine the concentration of various chemical species present in the radiopharmaceuticals (RPs). The present work describes three years of experience in a single institute for the measurement of these impurities in the RPs preparations. Methods: </strong...

BACKGROUND Predicting species' potential geographical range by species distribution models (SDMs) is central to understand their ecological requirements. However, the effects of using different modeling techniques need further investigation. In order to improve the prediction effect, we need to assess the predictive performance and stability of different SDMs. METHODOLOGY We collected the dis...

The objective of this study was to investigate the effects of the combined RF radiation (837 MHz CDMA plus 1950 MHz WCDMA) signal on levels of intracellular reactive oxygen species (ROS) in neuronal cells. Exposure of the combined RF signal was conducted at specific absorption rate values of 2 W/kg of CDMA plus 2 W/kg of WCDMA for 2 h. Co-exposure to combined RF radiation with either H2O2 or me...

During the last two decades, the number of macrocell mobile telephony base station antennas emitting radiofrequency (RF) electromagnetic radiation (EMR) in residential areas has increased significantly, and therefore much more attention is being paid to RF EMR and its effects on human health. Scientific field measurements of public exposure to RF EMR (specifically to radio frequency radiation) ...
