irritable bowel syndrome (ibs) is the most prevalent functional gastrointestinal disorder noted in the general population worldwide. its chronic nature, signs and symptoms which vary periodically from mild to severe have many negative effects on the quality of life for the sufferer; therefore the appropriate treatment of these patients is highly important. patients should be informed by their d...

Cell polarization is a key feature of T-cell function. The immunological synapse (IS) between T cells and antigen-presenting cells is a beautiful example of how polarization of cells is used to guide cell function. Receptors, signal transducers, the cytoskeleton, and organelles are enriched at or depleted from the IS after its formation, and in many cases these re-localizations have already bee...

Kupfer-type immunological synapses are thought to mediate intercellular communication between antiviral T cells and virally infected target Ag-presenting brain cells in vivo during an antiviral brain immune response. This hypothesis predicts that formation of Kupfer-type immunological synapses is necessary for polarized distribution of effector molecules, and their directed secretion toward the...

During the past few years technological advance have been allowed the developing of techniques that help to the diagnosis of multiple diseases. In the case of the autoimmune diseases, immunological techniques are helpful since they allow the detection of multiple autoantibodies at the same time with small volumes of sample. Together with the development of the new techniques, sensitivity and sp...

Synopsis A short history of the laboratory diagnosis of pregnancy is followed by an evaulation of four immunological methods of pregnancy diagnosis. The immunological methods based upon haemagglutination-inhibition and slide latex agglutination, gave a.lOO% accuracy. It is concluded that these techniques are suitable for the diagnosis of pregnancy after the 35th day following the last menstrual...
