INTRODUCTION AND OBJECTIVES Although bundle branch block (BBB) is regarded as a frequent finding, data on its prevalence are scarce in the general population and nonexistent in patients on dialysis. The aims of this study were to determine the prevalence of complete BBB in patients starting dialysis, to identify factors associated with its presence and, secondarily, to explore its association w...

The blood-brain barrier (BBB) controls the movement of substances into and out of the brain. The tight jun...

Growth hormone (GH) therapy is associated with improved neurobehavior, leading to the question whether GH crosses the blood-brain barrier (BBB) from blood after its release there from the pituitary, or whether GH exerts CNS effects by secondary mediators, particularly insulin-like growth factor (IGF)-1. GH release from the pituitary is controlled not only by hypothalamic factors, but also by gh...

Ongoing interest in brain ischemia research has provided data showing that ischemia may be involved in the pathogenesis of Alzheimer disease. Brain ischemia in the rat produces a stereotyped pattern of selective neuronal degeneration, which mimics early Alzheimer disease pathology. The objective of this study was to further develop and characterize cardiac arrest model in rats, which provides p...

During the past several years, there has been increasing interest in the role of the blood-brain barrier (BBB) in epilepsy. Advances in neuroradiology have enhanced our ability to image and study the human cerebrovasculature, and further developments in the research of metabolic deficiencies linked to seizure disorders (e.g., GLUT1 deficiency), neuroinflammation, and multiple drug resistance to...

Over 20 years ago, the Sadowski group separated two mouse lines, one with high (HA) and the other with low (LA) sensitivity to swim stress-induced analgesia (SSIA). Recently, we proposed that increased leakage of the blood-brain barrier (BBB) in the HA line created the difference in the response to SSIA. To search for further evidence for this hypothesis, differences in the levels of the BBB pr...

Blood-brain barrier (BBB) disruption is thought to facilitate the development of cerebral infarction after a stroke. In a typical stroke model (such as the one used in this study), the early phase of BBB disruption reaches a peak 6 h post-ischemia and largely recovers after 8-24 h, whereas the late phase of BBB disruption begins 48-58 h post-ischemia. Because cerebral infarct develops within 24...

The goal of brain drug targeting technology is the delivery therapeutics across blood barrier (BBB), including human BBB. Nose to has received a great deal attention as non- invasive, convenient and reliable system. For systemic targetedadministration drug. various deliveries through some transport pathways, Factor influencing nasal absorption, formulation strategies nose brain, colloidal carri...
