Escherichia coli is a bacterial species found ubiquitously in the intestinal flora of animals, although pathogenic variants cause major public health problems. Aptamers are short oligonucleotides that bind to targets with high affinity and specificity, and have great potential for use in diagnostics and therapy. We used cell-based Systematic Evolution of Ligands by EXponential enrichment (cell-...

Protein-protein interactions (PPI) are key molecular elements that provide the basis of signaling in virtually all cellular processes. The precision and specificity of these molecular interactions have ignited a strong interest in pursuing PPI surfaces as new targets for drug discovery, especially against ion channels in the central nervous system (CNS) where selectivity and specificity are vit...

The in vitro interaction of a fresh clinical isolate of Staphylococcus aureus and polymorphonuclear leukocytes was investigated. The importance of the various cellular constituents as host immunological factors was analyzed, and the results suggested that two components, namely, an acidic polysaccharide consisting of a predominance of aminogalacturonic acid and a strain-specific mucopeptide com...

emergency physicians, like other specialists, are faced with different patients and various situations each day. they have to use ancillary diagnostic tools like laboratory tests and imaging studies to be able to manage them. in most cases, numerous tests are available. tests with the least error and the most accuracy are more desirable. the power of a test to separate patients from healthy one...

abstract background the aim of this study was to evaluate sensitivity and specificity of mediastinal sonography, and compared with ct, in detection of anterior mediastinal neoplasms. materials and methods the sonography with convex probes (5.0 and 7.5 mhz) was done prospectively for 34 patients (from 2 to 25 years old) with mediastinal mass. the results were compared with the results of contras...

AIM The aim of this paper is to reveal the experiences and meaning of confidentiality for Australian nurses in the context of whistle blowing. BACKGROUND Despite the ethical, legal and moral importance of confidentiality within the health-care context, little work has addressed the implications of confidentially related to whistle-blowing events. METHODS The study used qualitative narrative...
