“Jjustification of Repeated Animal Experiments and Determination of the Required Number of Animals According to the German Animal Protection Act The repetition of animal experiments requires justification according to the German Animal Protection Act (Tierschutzgesetz). On the other hand, repetition of experiments is considered

necessary for the improvement of the precision and reliability of the results. In this paper it is shown that such improvement is not achieved by a repetition of the experiment but by repeated inclusion of animals into the experiment. The more animals are included, the SRT2104 cost more precisely and reliably the results can be

generalized to further situations. The number of animals necessary for a proposed precision can be determined with statistical methods. The basic ideas are explained in the paper and demonstrated with two examples. In long term experiments the precision can he improved, if all experimental conditions are applied within temporally homogenous blocks to few animals and the blocks are repeated till the necessary number of animals is reached (block experiments). By sequential interim analyses, where at each analysis on the basis of all available data a decision on continuation or conclusion of the experiment is drawn, a further reduction of the number of animals can be achieved. These methods are discussed in the paper. Repetitions of total animal experiments are justified, if there exist legitimate doubts on the soundness of the published results or if in so called ring-experiments the variability of the results between different laboratories should be investigated.”
“This

review summarizes analytical determinations using bismuth screen-printed electrodes (Bi-SPEs). We emphasize fundamental understanding of the design and the fabrication of learn more these economical disposable sensors that are environment friendly. The methods of coating the Bi on the working surface and their potential modifications are used to classify the types of Bi-SPE. We present tables with the most significant information from the accessible literature. (C) 2013 Elsevier Ltd. All rights reserved.”
“Juvenile xanthogranuloma (JXG) is a histiocytic inflammatory disorder that can present different histologic patterns. Classic JXG consists of sheets of foamy histiocytes and numerous multinucleated Touton giant cells. Nonlipidized JXG (NJXG) is one of the unusual variants of JXG, consisting of a diffuse monomorphic infiltrate of mononuclear histiocytes, suggesting an aggressive or malignant tumor due the high mitotic index. However, NJXG behaves clinically as classic JXG. We present an unusual case of a 6-year-old boy who presented an exophytic ulcerated nodule on the lower lip diagnosed as NJXG.
