Each fall, eastern North American monarch butterflies (Danaus plexippus) use a time-compensated sun compass to migrate to their overwintering grounds in central Mexico. The sun compass mechanism involves the neural integration of skylight cues with timing information from circadian clocks to maintain a constant heading. The neuronal substrates for the necessary interactions between compass neur...

The article examines the importance of special tools on basis new conceptual ideas related to humanization forms and methods law enforcement. It is emphasized that in implementation public safety order enforcement agencies must meet requirements rule law, according which man, his rights freedoms are recognized as highest values determine content direction state its legal institutions. use means...

In this paper, we propose a genetic algorithm, called GenSPN, for finding highly probable differential characteristics of substitution permutation networks (SPNs). A special fitness function and a heuristic mutation operator have been used to improve the overall performance of the algorithm. We report our results of applying GenSPN for finding highly probable differential characteristics of Ser...

A case of a benign clear cell ('sugar') tumour of the lung in a 61-year-old woman is presented. Characteristic routine histological features are provided and problems concerning differential diagnosis are discussed. Immunohistochemical stainings for the intracytoplasmatic intermediate filament proteins keratin and vimentin in our patient suggest a mesenchymal origin for this rare pulmonary neop...

Foxp3 Tregs are essential for maintaining immune tolerance in mice and men. Except for expression in a minor population of CD8 T cells,1 Foxp3 is currently believed to be restricted to CD4 Tregs in mice, because widespread nonhematopoietic Foxp3 expression and its putative implication in tolerance have been refuted.2,3 Thus, the employment of Foxp3 reporter mice, including Foxp3DTR-eGFP (DEREG)...
