The purpose of this study is to evaluate the safety and efficacy of the ExAblate Model 4000 Type 2.0 System as a tool to disrupt the blood-brain barrier (BBB) in patients with probable Alz...
Aging is the primary risk factor in aging-related dementia. An important initiating factor for the development and progression of cognitive impairment is disruption of the blood-brain barr...
The purpose of this study is to evaluate the safety of blood-brain barrier (BBB) disruption in adult patients with a first presentation of a glioblastoma (GBM) following a maximal safe sur...
This is a prospective, non-randomized, single-arm, feasibility study to evaluate the safety and initial effectiveness of opening of the Blood-Brain Barrier with intravenous contrast agents...
The purpose of this study is to evaluate the blood brain barrier in the striatum of patients that have other types of movement disorders compared to patients with Parkinson's Disease that ...
Alzheimer's disease, a type of dementia, affects memory, behavior, and cognitive processes in affected individuals. It is one of the prominent diseases, accounting for 60-80% of dementia cases and aff...
Though Alzheimer's disease (AD) has been studied for more than a century, to date, no drug has provided a definitive cure. The slow development of the disease and the time lag between pathological cha...
The aims of this study were to report brain characteristic abnormalities and to evaluate the relationship of blood-brain barrier (BBB) disruption and brain lesions in Chinese patients with NMOSD.
The blood-brain barrier (BBB) is involved in the pathogenesis of Alzheimer's disease (AD). BBB is a highly selective semipermeable structural and chemical barrier which ensures a stable internal envir...
The blood-brain barrier (BBB) disruption and the following development of brain edema, is the most life-threatening secondary injury after intracerebral hemorrhage (ICH). This study is to investigate ...
A cholinesterase inhibitor that crosses the blood-brain barrier. Tacrine has been used to counter the effects of muscle relaxants, as a respiratory stimulant, and in the treatment of Alzheimer's disease and other central nervous system disorders.
The property of blood capillary ENDOTHELIUM that allows for the selective exchange of substances between the blood and surrounding tissues and through membranous barriers such as the BLOOD-AIR BARRIER; BLOOD-AQUEOUS BARRIER; BLOOD-BRAIN BARRIER; BLOOD-NERVE BARRIER; BLOOD-RETINAL BARRIER; and BLOOD-TESTIS BARRIER. Small lipid-soluble molecules such as carbon dioxide and oxygen move freely by diffusion. Water and water-soluble molecules cannot pass through the endothelial walls and are dependent on microscopic pores. These pores show narrow areas (TIGHT JUNCTIONS) which may limit large molecule movement.
The barrier between the perineurium of PERIPHERAL NERVES and the endothelium (ENDOTHELIUM, VASCULAR) of endoneurial CAPILLARIES. The perineurium acts as a diffusion barrier, but ion permeability at the blood-nerve barrier is still higher than at the BLOOD-BRAIN BARRIER.
Specialized non-fenestrated tightly-joined ENDOTHELIAL CELLS with TIGHT JUNCTIONS that form a transport barrier for certain substances between the cerebral capillaries and the BRAIN tissue.
The selectively permeable barrier, in the EYE, formed by the nonpigmented layer of the EPITHELIUM of the CILIARY BODY, and the ENDOTHELIUM of the BLOOD VESSELS of the IRIS. TIGHT JUNCTIONS joining adjacent cells keep the barrier between cells continuous.
