Elastomeric Micro‐Balloons for Remote Control of Cerebral Blood Flow and Real‐Time In vivo Imaging of Rodent Brain Response to Hypoperfusion

Advanced Materials, EarlyView.
This study reports the fabrication of MRI‐compatible elastomeric micro‐balloons via a multi‐step bubble casting process, where the monolithic elastomeric wall is selectively stiffened for reversible and controlled inflation and elasticity, depending on the target vessels for graded occlusion of cerebral arteries.

Modulation of firing and synaptic transmission of serotonergic neurons by intrinsic G protein-coupled receptors and ion channels

Frontiers in Integrative Neuroscience, 2013
Serotonergic neurons project to virtually all regions of the CNS and are consequently involved in many critical physiological functions such as mood, sexual behavior, feeding, sleep/wake cycle, memory, cognition, blood pressure regulation, breathing and ...

Optimising the assessment of cerebral autoregulation from black box models

, 2014
Cerebral autoregulation (CA) mechanisms maintain blood flow approximately stable despite changes in arterial blood pressure. Mathematical models that characterise this system have been used extensively in the quantitative assessment of function ...

Linking Stochastic Dynamics to Population Distribution: An Analytical Framework of Gene Expression [PDF]

, 2006
We present an analytical framework describing the steady-state distribution of protein concentration in live cells, considering that protein production occurs in random bursts with an exponentially distributed number of molecules.

Targeted Perfusion Therapy in Spinal Cord Trauma. [PDF]

, 2020
We review state-of-the-art monitoring techniques for acute, severe traumatic spinal cord injury (TSCI) to facilitate targeted perfusion of the injured cord rather than applying universal mean arterial pressure targets.

Natural History of Chronic Kidney Disease in Sickle Cell Disease

American Journal of Hematology, EarlyView.
ABSTRACT Kidney complications, referred to as nephropathy, develop early in sickle cell disease (SCD). In addition to its known morbidity, abundant data show that chronic kidney disease (CKD) is associated with an increased mortality risk in SCD. Increasing evidence suggests that the natural history of SCD nephropathy is progressive. Initial glomerular

Cerebral blood flow autoregulation is impaired in schizophrenia [PDF]

, 2017
Patients with schizophrenia have a higher risk of cardiovascular diseases and higher mortality from them than does the general population; however, the underlying mechanism remains unclear.

Tissue oxygenation dynamics during transition from seizure to spreading depolarization in rat brain

Epilepsia, EarlyView.
Abstract Objective Spreading depolarization (SD) is a phenomenon underlying various neurological conditions, including epilepsy. Researchers have suspected that local tissue oxygenation breakdown induces spontaneous SD. In this study, we investigated the relationship between spontaneous epileptic seizures and SD, with a focus on the role of local ...

Detection of impaired cerebral autoregulation improves by increasing arterial blood pressure variability

, 2012
Although the assessment of dynamic cerebral autoregulation (CA) based on measurements of spontaneous fluctuations in arterial blood pressure (ABP) and cerebral blood flow (CBF) is a convenient and much used method, there remains uncertainty about its ...
