Article Abstract
Aneurysmal subarachnoid hemorrhage (SAH) has increased with the aging of the population, but the outcome for elderly SAH patients is very poor. Therefore, predicting the outcome is important for determining whether to pursue aggressive treatment. Pigment epithelium-derived factor (PEDF) is a matricellular protein that is induced in the brain, and the plasma levels could be used as a biomarker for the severity of metabolic diseases. This study investigated whether acute-phase plasma PEDF levels could predict outcomes after aneurysmal SAH in the elderly. Plasma samples and clinical variables were collected over 1-3 days, post-SAH, from 56 consecutive elderly SAH patients ≥75 years of age registered in nine regional stroke centers in Japan between September 2013 and December 2016. The samples and variables were analyzed in terms of 3-month outcomes. Acute-phase plasma PEDF levels were significantly elevated in patients with ultimately poor outcomes, and the cutoff value of 12.6 µg/mL differentiated 3-month outcomes with high sensitivity (75.6%) and specificity (80.0%). Acute-phase plasma PEDF levels of ≥12.6 µg/mL were an independent and possibly better predictor of poor outcome than previously reported clinical variables. Acute-phase plasma PEDF levels may serve as the first biomarker to predict 3-month outcomes and to select elderly SAH patients who should be actively treated.

Impact of platelet transfusions on plasma proteomes in controlled endotoxemia and in hemato-oncological patients.

Background: Inflammation is a hallmark of patients that receive platelet transfusions, including critically ill and hemato-oncological patients. Platelet transfusions have been suggested to exacerbate inflammatory conditions, resulting in transfusion-related complications. Here, we used plasma proteomics to study the impact of platelet transfusions under inflammatory conditions.

Objectives: This research aimed to investigate the effect of 2 types of exercise on apoptosis, neurogenesis, and angiogenesis factors in the penumbra area of stroke during the rehabilitation period after stroke.
Materials And Methods: A transient distal middle cerebral artery occlusion (td-MCAO) model was used to induce stroke and after that, the animals were randomly divided into three groups: stroke, stroke + continuous exercise with increasing duration (CTID), and stroke + exercise with increasing intensity (CTII). At 24 hr spost-stroke , MRA, neurological deficit, and behavioral tests were conducted, and also continuous exercises were conducted for five consecutive days, Finally, MRI and behavioral tests were performed, and 24 hr after that, tissue separation and blood sampling were performed to evaluate plasma irisin, Extracellular Signal-Regulated Kinases 1 and 2 (ERK1/2) / cAMP Response Element-Binding Protein (CREB) / 90 kDa Ribosomal S6 Kinase (P90RSK) pathway, Vascular Endothelial Growth Factor (VEGF) / Vascular Endothelial Growth Factor Receptor 2 (VEGF-R2), and Brain-Derived Neurotrophic Factor (BDNF) / Tropomyosin Receptor Kinase B (TrKB) levels.

Traumatic brain injury is not constrained only to the brain but delayed secondary events disturb the end organ functioning via intense response of three homeostatic mechanisms such as sympathetic activity, inflammation, and immunosuppression. Current study involved weight drop model to induce TBI in Swiss albino mice. Eprosartan was administered orally after 30-45 min post injury to mice in 0.

Background: Cardioembolic (CE) stroke is a common and often severe subtype of ischemic stroke, but early and accurate differentiation from other stroke types remains challenging. Brain natriuretic peptide (BNP) and N-terminal pro-BNP (NT-proBNP) have emerged as promising biomarkers, yet direct comparative studies evaluating their diagnostic utility in the hyperacute and early acute phase are limited.
Methods: This prospective study included 165 patients who presented with acute stroke symptoms within twenty-four hours of onset at a single tertiary center.

Ischemic stroke (IS) represents a substantial global health threat, but only a few effective medicines exist to treat IS, with a huge unmet clinical need. Idebenone (IDB), a coenzyme Q10 analogue, has multitarget effects, including enhancing mitochondrial energy metabolism, scavenging free radicals, and anti-inflammation, which is approved in Europe for treating Leber's hereditary optic neuropathy (LHON). However, IDB has poor water solubility and oral bioavailability, resulting in insufficient therapeutic plasma concentrations, even following high-dose oral administration, and limiting its use for brain diseases and acute-phase interventions.
