The distribution of AQP4 in the non-human primate brain was observed in perivascular astrocytes, comparable to the observation made in the rodent brain. In contrast with rodent, primate AQP1 is expressed in the processes and perivascular endfeet of a subtype of astrocytes mainly located in the white matter and the glia limitans, possibly involved in water homeostasis. AQP1 was also observed in neurons innervating the pial blood vessels, suggesting
a possible role in cerebral blood flow regulation. As described in rodent, AQP9 mRNA and protein were detected in astrocytes and in catecholaminergic neurons. However additional locations were observed for AQP9 in populations of neurons Givinostat located in several cortical areas of primate brains. This report describes a detailed study of AQP1, AZD0156 research buy 4 and 9 distributions in the non-human primate brain, which adds to the data already published in rodent brains. This relevant species differences have to be considered carefully to assess potential drugs acting on AQPs non-human primate models before entering human clinical trials. (C) 2010 IBRO.

“Background New DNA-based microarray platforms enable rapid detection and species identification of many pathogens, including bacteria. We assessed the sensitivity, specificity,
and turnaround time of a new molecular sepsis assay.
Methods 2107 positive blood-culture samples of 3318 blood samples from patients with clinically suspected sepsis were investigated for bacterial
species by both conventional culture and Prove-it sepsis assay (Mobidiag, Helsinki, Finland) in two centres (UK and Finland). The assay is a novel PCR and microarray method that is based on amplification and detection of gyrB, parE, and mecA genes of 50 bacterial species. Operators of the test assay were not aware of culture results. We calculated sensitivity, specificity, and turnaround time according to Clinical and Laboratory Standards Institute recommendations.
Findings 1807 of 2107 (86%) positive blood-culture samples included a pathogen covered by the assay. The assay had a clinical sensitivity of 94.7% (95% CI 93.6-95.7) and a specificity of 98.8% (98.1-99.2), and 100% for both measures for meticillin-resistant Staphylococcus aureus bacteraemia. The assay was a mean 18 h faster than was the Selonsertib cell line conventional culture-based method, which takes an additional 1-2 working days. 34 of 3284 (1.0%) samples were excluded because of technical and operator errors.
Interpretation Definitive identification of bacterial species with this microarray platform was highly sensitive, specific, and faster than was the gold-standard culture-based method. This assay could enable fast and earlier evidence-based management for clinical sepsis.”
