Involvement of ROS in BBB dysfunction

Free Radical Research, 2009
The blood-brain barrier (BBB) forms a protective barrier around the brain, with the important function of maintaining brain homeostasis. Pathways thought to initiate BBB dysfunction include the kinin system, excitotoxicity, neutrophil recruitment, mitochondrial alterations and macrophage/microglial activation, all of which converge on the same point ...

Anatomy of the BBB

2001
The central nervous system (CNS) takes its origin from the ectodermal tissue. In the blastula, those cells, which will form the CNS, invaginate to create a depression: the tips of this structure fuse in order to develop a tube. During the early stages, a single cell layer constitutes this tube.

Pathophysiology of BBB

2001
The CNS macro-and micro-vessels occupy a significant 25 to 30% of the total brain volume. Continuous tight-junctioned cerebral capillary endothelium comprising the BBB needs to be viewed as two separate impermeable cellular membranes, one on the inside of the vessel wall (luminal side) and the other on the outside (abluminal side) separated by 300-to ...

Constant angle surfaces in $ {\Bbb S}^2\times {\Bbb R} $

Monatshefte für Mathematik, 2007
In this article we study surfaces in \( {\Bbb S}^2\times {\Bbb R} \) for which the unit normal makes a constant angle with the \( {\Bbb R} \)-direction. We give a complete classification for surfaces satisfying this simple geometric condition.

[The Blood-Brain Barrier (BBB) and in vitro BBB Models].

Brain and nerve = Shinkei kenkyu no shinpo, 2015
The blood-brain barrier (BBB) is a brain-specific capillary barrier critical for preventing entry of toxic substances into the central nervous system. In contrast to vessels of peripheral organs, the BBB limits the exchange of inflammatory cells and mediators under physiological and pathological conditions.

Gene Expression Changes and Progression to a BBB Phenotype in a Dynamic Model of the BBB

2001
It is well established that mammalian endothelial cells (EC) acquire specialized functions in response to a variety of cellular, molecular and physical stimuli. While for most cell types, chemical signals play a pivotal, if not unique, role in determining cell physiology.

C*-ALGEBRAS GENERATED BY A PROJECTION AND THE REDUCED GROUP C*-ALGEBRAS ${C^*_r\Bbb Z*\Bbb Z_n}$ AND ${C^*_r\Bbb Z_m*\Bbb Z_n}$

International Journal of Mathematics, 2005
Let Γ=ℤm * ℤn or ℤ * ℤn, and let Γ(h) be the subtree consisting of all reduced words starting with any reduced word h ∈ Γ\{e}. We prove that the C*-algebra [Formula: see text] generated by [Formula: see text] and the projection Ph onto the subspace ℓ2(Γ(h)) has a unique nontrivial closed ideal ℐ, ℐ is *-isomorphic to [Formula: see text], and the ...
