P 61: MicroRNA as a Therapeutic Tool to Prevent Blood Brain Barrier Dysfunction in Neuroinflammation

Endothelial cells present in brain are unique and differ from other peripheral tissues in a number of ways, which ensures specific brain endothelial barrier properties. Endothelial dysfunction is the earliest event in the initiation of vascular damage caused by inflammation. Various microRNAs (miRNA) have been discovered in different cellular components of the blood bran barrier (BBB). miRNAs a...

Microcalorimetry as a tool for evaluation of blood culture media.

Evaluation of optimal compositions of blood culture media has called for extensive and laborious work in comparative studies of large series of clincal specimens. Bacterial growth is accompanied by heat production, and calorimetry provides an analytical tool for its detection and quantification. A twin microcalorimeter of the heat conduction type was used to register heat effects in experimenta...

The occult blood test.

The original occult blood tests were designed for forensic purposes, Schonbein and van Deen using a chemical test with guaiacum which was more sensitive than the older Teichmann's haemin crystal test. Subsequently similar chemical methods were widely used and in I893 Weber described his version of the guaiacum test for detecting occult blood in the faeces. Boas first made extensive use of this ...
