INTRODUCTION Every year million people have poisoning. Most of them will duo to severity of complications. Identifying the pattern of poisoning will help to prevent of them. Because of the non-medicine substance have a wide variety range and easily is used among people, so the aim of this study was to determine frequency of non-medicinal poisoning according to 10th revision of International Cla...

Organic cation transporters play an important role in the absorption, distribution, and elimination of clinical agents, toxic substances, and endogenous compounds. In kidney preparations, significant differences in functional characteristics of organic cation transport between various species have been reported. However, the underlying molecular mechanisms responsible for these interspecies dif...

Step 1 Extraction One of two methods can be used. In solid phase extraction the sample is put on a plate coated with a substance that organic compounds (such as drugs) do not adhere to, but to which other compounds in the sample do, and then the organics washed off with a suitable solvent. In liquid-liquid extraction an organic solvent is mixed with the sample, the organic compounds migrate to ...

The gravity receptors of all vertebrates utilize a “test mass” consisting of a complex arrangement of mineral and organic substance that lies over the sensory receptor areas ( m a c u l a ~ ) . ~ ~ Carlstrom has shown that in most vertebrates, the mineral is a polymorph of calcium carbonate (vaterite, aragonite, calcite] in the form of minute, single crystals called otoconia (“ear dust”)? The o...

Atmospheric SO2 emissions in the UK and globally increased 6- and 20-fold, respectively, from the mid-1800s to the 1960s resulting in increased S deposition, acid rain, and concurrent acidification of terrestrial and aquatic ecosystems. Structural analyses using synchrotron-based X-ray near-edge spectroscopy (XANES) on humic substance extracts of archived samples from the Rothamsted Park Grass ...
