Quercetin-3-glucuronide (Q3GA), the main phase II metabolite of quercetin (Q) in human plasma, is considered to be a more stable form Q for transport with bloodstream tissues, where it can potentially deconjugated by β-glucuronidase (β-Gluc) aglycone, which easily enters brain. This study evaluates effect lipopolysaccharide (LPS)-induced acute inflammation on β-Gluc gene expression choroid plex...

introduction: in iran, thousands of young individuals become victims of head injury annually. head injury can damage neuronal cells which may in turn complicate the recovery of the patients. also, the increase of iron in cerebrospinal fluid (csf) following head injury may contribute to the hypoxic-ischemia brain damage by catalyzing the formation of free radicals (harber-weiss rection). the obj...

Background: Recent studies have shown that bone marrow mesenchymal stem cells (BMSCs) have a putative ability to promote neurogenesis and produce behavioral and functional improvement. Our previous study demonstrated that co-treatment of granulocyte colony-stimulating factor (G-CSF) and BMSCs have beneficial effects on Parkinson's models. The main purpose of this research was to investigate the...

To the Editor: Acute encephalitis/encephalopathy associated with human metapneumovirus (HMPV) has been documented in children (1–3). Recently, Fok et al. (4) described an encephalitis case in an adult but were unable to test cerebrospinal fluid (CSF) for HMPV. Following authors’ recommendations, we performed diagnostic testing on the CSF of an adult with HMPV-associated encephalitis. A previous...

Due to the effort of several research teams across the world, today we have a solid base of knowledge on the liquid contained in the brain cavities, its composition, and biological roles. Although the cerebrospinal fluid (CSF) is among the most relevant parts of the central nervous system from the physiological point of view, it seems that it is not a permanent and stable entity because its com...

The level of granulocyte-macrophage colony-stimulating factor (GM-CSF) mRNA is fourfold lower in phorbol myristate acetate (PMA) + phytohemagglutinin (PHA)-activated mononuclear cells (MNC) from newborns compared with adults. The GM-CSF transcription rate is similar in umbilical cord and adult MNC, but transcript half-life is threefold lower in cord activated MNC. Interaction of RNA binding pro...

Erythroid progenitors (BFU-E) from adult human peripheral blood generate erythroid bursts in semisolid culture supplemented with at least two growth factors, ie, erythropoietin (Ep) and interleukin-3 (IL-3) or granulocyte-macrophage colony-stimulating factor (GM-CSF). We have analyzed the hematopoietin(s) requirement of human embryonic BFU-E, as compared to that of adult peripheral blood progen...

During embryonic development and adult life, brain cavities and ventricles are filled with cerebrospinal fluid (CSF). CSF has attracted interest as an active signaling medium that regulates brain development, homeostasis and disease. CSF is a complex protein-rich fluid containing growth factors and signaling molecules that regulate multiple cell functions in the central nervous system (CNS). Th...
