Angiosarcoma of the heart is a rare malignancy that can present in many ways. It is an important diagnosis to consider in patients presenting with otherwise unexplained tamponade-type symptoms. Here we present a case of a young male who presented with hemorrhagic tamponade and underwent resection of a large angiosarcoma of the right atrium. In this case, we describe the rare presentation of ang...

One of the important challenges in the emerging field of synthetic biology is designing artificial networks that achieve coordinated behavior in cell communities. Here we present a synthetic multicellular bacterial system where receiver cells exhibit transient gene expression in response to a long-lasting signal from neighboring sender cells. The engineered sender cells synthesize an inducer, a...

Genomes of Salmonella enterica isolates, including those linked to outbreaks of produce-associated gastroenteritis, contain sdiA, which encodes a receptor of N-acyl homoserine lactones (AHL). AHL are the quorum-sensing signals used by bacteria to coordinately regulate gene expression within -their populations. Because S. enterica does not produce its own AHL, SdiA is hypothesized to function in...

In order to perform single-cell analysis and online studies of N-acyl homoserine lactone (AHL)-mediated communication among bacteria, components of the Vibrio fischeri quorum sensor encoded by luxR-P(luxI) have been fused to modified versions of gfpmut3* genes encoding unstable green fluorescent proteins. Bacterial strains harboring this green fluorescent sensor detected a broad spectrum of AHL...

Hemorrhagic cystitis — an inflammatory disease of the bladder with a complex etiology. The frequency of this pathology has increased substantially due to the increase in the number of patients undergoing radiation therapy for malignant neoplasms ofpelvic organs. The development of a rational treatment for hemorrhagic cystitis is a difficult problem. Given the pathogenetic basis of this disease,...

OBJECTIVE Hyperdense lesions can frequently be observed on the CT obtained immediately after intra-arterial (IA) thrombolysis, and it is sometimes difficult to differentiate contrast extravasation from the hemorrhagic lesions. The purposes of this study are to classify the hyperdense lesions according to their morphologic features and to track the outcome of those lesions. MATERIALS AND METHO...

| This paper gives a survey over a self{ contained part of the ESPRIT-project \FORMAT", which developes a prover for VHDL{based hardware design. Notable is the use of a graphical speci cation language called STD (Symbolic Timing Diagrams), which can be seen as a visual dialect of temporal logic. The heart of the prover is built by two powerful industrial veri cation tools: A (compositional) sym...

This study investigated the physiological demands of women's field hockey competition and compared these demands to those experienced during game-based training activities. Fourteen elite women field hockey players (mean +/- SD; age, 23.3 +/- 3.2 years; maximal oxygen consumption, 53.5 +/- 4.3 ml x kg(-1) x min(-1)) participated in this study. Global positioning satellite (GPS) system analysis ...

An investigation of name-bearing types and other relevant type specimens of twelve nominal Leptopelis taxa described from or distributed in the Eastern Arc Mountains in East Africa was carried out. Our aim was to clarify their status and where necessary revise respective nomina. We suggest several nomenclatural and taxonomic actions: 1) Leptopelis barbouri Ahl, 1929 is transferred to the synony...

N-Acylhomoserine lactone (AHL)-degrading enzyme, AiiM, was identified from the potato leaf-associated Microbacterium testaceum StLB037. In this study, we cloned eight aiiM gene homologues from other AHL-degrading Microbacterium strains. The similarity of the chromosomal locus of the aiiM gene is associated with the phylogenetic classification based on 16S rRNA. Degenerate PCR revealed that the ...
