13. SPEM, sistema pulso-eco microcontrolado para geração e medição de campos ultra-sonicos
In order to obtain more reliability in the processing of information obtained by ultrasound radiation, it is very important to understand the basic principIes of ultrasound wave generation, interaction with and propagation through different media. This can be partially achieved with suitable equipments and a good knowledge of its working conditions. In an ef

14. Characterization of Two Novel Pyrogenic Toxin Superantigens Made by an Acute Rheumatic Fever Clone of Streptococcus pyogenes Associated with Multiple Disease Outbreaks
The pathogenesis of acute rheumatic fever (ARF) is poorly understood. We identified two contiguous bacteriophage genes, designated speL and speM, encoding novel inferred superantigens in the genome sequence of an ARF strain of serotype M18 group A streptococcus (GAS). speL and speM were located at the same genomic site in 33 serotype M18 isolates, and no nuc

15. Two Novel Superantigens Found in Both Group A and Group C Streptococcus
Two novel streptococcal superantigen genes (speLSe and speMSe) were identified from the Streptococcus equi genome database at the Sanger Center. Genotyping of 8 S. equi isolates and 40 Streptococcus pyogenes isolates resulted in the detection of the orthologous genes speL and speM in a restricted number of S. pyogenes isolates (15 and 5%, respectively). Surp

16. Altered gastric chief cell lineage differentiation in histamine-deficient mice
The orderly differentiation of cell lineages within gastric glands is regulated by a complicated interplay of local mucosal growth factors and hormones. Histamine secreted from enterochromaffin-like cells plays an important role in not only stimulated gastric acid secretion but also coordination of intramucosal growth and lineage differentiation. We have exa
