This pilot research trial studies blood brain barrier differences in patients with brain tumors undergoing surgery. Studying samples of tissue and blood from patients with brain tumors in the laboratory may help doctors to understand how well drugs get into different parts of a brain tumor. This may help them to determine which types of drugs may be best for treating brain tumors.
The purpose of this study is to find out a serum marker for the evaluation of blood brain barrier damage based on animal experiments and investigate the effect of NBO（Normobaric hyperoxia）on blood brain barrier in the acute ischemic stroke patients who received r-tPA thrombolytic therapy.
AVI-4020 Injection, a phosphorodiamidate Morpholino oligomer (PMO), was found to cross the blood-brain barrier during a study of patients with presumptive West Nile virus disease. AVI-4065, which was designed to target HCV, is also a PMO; its ability to cross the blood-brain barrier is unknown. In this study, a single dose of AVI-4065 will be subcutaneously injected, and samples collected to determine if this drug crosses the blood-brain barrier. If it does, then additional ...
This is a study to determine if Magnetic Resonance Imaging (MRI) techniques can detect early changes in white matter (in the brain) and the blood-brain barrier resulting from radiation therapy.
The purpose of this research study is to determine if sunitinib can get past the blood-brain barrier and into the brain tumor. Sunitinib has shown promising results in treating other cancers and works by blocking blood flow to tumors, which may prevent them from growing further. At the present time, there is no chemotherapy that can cure glioblastoma. The reason why chemotherapy is not fully effective is that many drugs cannot penetrate into brain tumors. This is due to the...
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 are receiving similar treatment, to determine if a there is a disruption of the blood brain barrier in patients with Parkinson's Disease.
The purpose of this study is to evaluate the safety, tolerability, and feasibility of Blood-Brain Barrier (BBB) opening using transcranial MRI-guided focused ultrasound in conjunction with an intravenous ultrasound contrast agent in patients with Amyotrophic Lateral Sclerosis (ALS).
The purpose of this study is to evaluate the safety of the ExAblate Model 4000 Type 2.0 used as a tool to disrupt the BBB (blood brain barrier) in patients with high grade glioma undergoing standard of care therapy.
The development and progression of multiple sclerosis seem to be driven by concomitant inflammation and, to a less well-defined degree, disturbances in metabolism of individual cells of the human central nervous system as well as changes in the dynamical supply of blood to the brain. These alterations in normal physiology can be quantified by investigating the change in specific parameters over the time course of multiple sclerosis evolution. Amongst these specific parameters, ...
This project aims to contribute knowledge to early MS disease mechanisms at the brain-blood interface using a combined immunological and neuroimaging approach. The aim is to provide a novel vascular model to assess MS disease activity, and to explore its potential as an early diagnostic biomarker, prior to blood-brain barrier disruption. Additionally, the investigators want to investigate influence of immune receptor defects upon disease activity and MS brain vascular system. ...
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 surgical resection and standard chemo-radiation with temozolomide (TMZ) protocol and ready for the maintenance phase of the Stupp protocol with TMZ.
Hypothesis: During severe brain trauma (injury, surgery) the ensuing inflammatory response in the central nervous system (CNS) results in a decrease in the expression of the transporter protein p-glycoprotein (PGP) in the blood brain barrier. This loss results in the penetration into the brain of certain drugs that are normally excluded by the transporter protein. In this study the working hypothesis is that the agitation observed in patients with CNS trauma treated with morp...
In Type 2 Diabetes mellitus patients we will: 1. quantify vasculopathy and blood-retinal barrier (BRB) leakage 2. measure blood-brain barrier (BBB) permeability and neuroanatomical changes 3. correlate BRB pathology with BBB breakdown, inflammatory markers and neuropsychiatric sequela
This study is designed to assess the safety and feasibility of using the ExAblate, Type 2 to temporarily disrupt the blood brain barrier in non-enhancing suspected glioblastomas. The ExAblate Model 4000 Type-2 is intended for use as a tool to disrupt the BBB.
T.to investigate a possible mechanism of the glucocorticosteroid receptors (GR) defect in patients with severe COPD by studying the effect of dexamethasone (Dex) on GR- binding, interleukin production (IL-6/IL-8) and MKP-1 expression in peripheral blood mononuclear cells blood (PBMC)
Because AVI-4020 Injection was found to cross the blood-brain barrier, and because AVI-4126 (RESTEN-NG) has potential medical benefit to people with a variety of diseases, including cancers, this study is being performed to find out if AVI-4126 also crosses the blood-brain barrier. If it does, then additional investigations could be performed, such as in people with certain types of cancer.
The blood-brain barrier regulates the passage of peripheral built appetite-suppressing hormones from the blood to the brain and informs the brain about the nutritional- and energy status. The aim of this study is to investigate in which extent the hormones are able to overcome the blood-brain barrier and how long it takes after food intake. Relating thereto indications to the effect of peripheral hormones in the central nervous system and the role of these hormones in th...
RATIONALE: Drugs used in chemotherapy, such as etoposide, carboplatin, and melphalan, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Chemoprotective drugs, such as sodium thiosulfate, may protect normal cells from the side effects of chemotherapy. Blood-brain barrier disruption uses certain drugs, such as mannitol, to open the...
PURPOSE: The purpose of this study is to determine whether transient opening of the blood-brain barrier by pulsed ultrasound using the SonoCloud implantable ultrasound device is safely tolerated in patients with recurrent glioblastoma immediately before systemic delivery of carboplatin-based chemotherapy. STUDY HYPOTHESIS: The blood-brain barrier can be safely opened using pulsed ultrasound prior to chemotherapy administration in patients with recurrent glioblastoma. Transie...
