Endovascular therapy for cerebral vasospasm after aneurysmal subarachnoid hemorrhage: Single-center experience in a high-volume neurovascular unit.

Introduction: Despite targeted standard therapy, aneurysmal subarachnoid hemorrhage (aSAH) frequently leads to cerebral vasospasms (CVS) of large cerebral arteries, reduced oxygen supply of brain tissue, known as delayed cerebral ischemia (DCI), subsequent development of manifest cerebral infarction and poor neurological outcome.

Research Question: The primary aim was to evaluate the efficacy of endovascular spasmolysis (eSL) as a rescue therapy for delayed ischemic neurological deficits (DIND) occurring despite maximum conservative treatment, with the potential benefit of preventing permanent ischemic deficits, and thus, improving overall neurological outcomes.

Material And Methods: In our retrospective, monocentric study, we included 310 patients developing CVS during hospitalization and evaluated their clinical and radiographic outcomes.

Cationic lipid transfection induces nuclear actin filaments.

Cationic lipids are widely used for gene delivery. Here, we report the transient formation of nuclear actin filaments in mammalian cells transfected with commercially available transfection reagents regardless of the proteins transfected. Readily detectable with phalloidin, nuclear actin ranges from short filaments to a fully developed network.

Repeated FRAP of the actin-binding protein CapG in the cell nucleus-a functional assay for EGF signaling in the single live breast cancer cell.

Compartmentalization and differential distribution of proteins within a cell maintain cellular function and viability. CapG is a gelsolin-related actin-binding protein that distributes in steady state diffusively throughout cytoplasm and cell nucleus. To detect changes in CapG's nucleocytoplasmic shuttling in response to external stimuli on the single cell level, we established repeated FRAP experiments of one and the same breast cancer cell.

Nebulized Lipopolysaccharide Causes Delayed Cortical Neuroinflammation in a Murine Model of Acute Lung Injury.

Lung injury caused by respiratory infection is a major cause of hospitalization and mortality and a leading origin of sepsis. Sepsis-associated encephalopathy and delirium are frequent complications in patients with severe lung injury, yet the pathogenetic mechanisms remain unclear. Here, 70 female C57BL/6 mice were subjected to a single full-body-exposure with nebulized lipopolysaccharide (LPS).
