To evaluate the anti-angiogenic efficacy of CB-12181 [an azasugar derivative that has inhibitory actions against matrix metalloproteinases (MMPs) and tumor necrosis factor-α (TNF-α) converting enzyme (TACE)], we investigated the suppressing ability on in vitro (tube formation by endothelial cells) and in vivo (retinal neovascularization on murine ischemia-induced proliferative retinopathy) models of angiogenesis. For in vitro a Read More

Near Infrared Spectroscopy (NIRS) is an emerging technique for brain oxygenation monitoring in newborns complicated by acute and chronic hypoxia. However, data regarding cerebral oxygenation normal values are still lacking and matter of debate. Therefore, we investigate whether NIRS parameters in healthy preterm/term infants are gestational age and delivery modalities dependent and correlated with standard m Read More

White matter lesions (WML) are a frequent finding on brain magnetic resonance imaging scans. Elevated blood pressure (BP) is consistently identified as risk factor for WML. However, it is unknown whether BP still is associated with WML in patients manifesting vascular disease. The aim of this cross-sectional study was to investigate associations between BP and WML in patients manifesting vascular disease. A total of 103 Read More

Stroke has been shown to lead to depressive disorders, anxiety disorders and other emotional consequences. Although the cause of these disorders is a subject of debate, stroke has clearly been shown to lead to the production of pro-inflammatory cytokines, which we hypothesized to play a role in the production of post-stroke emotional disorders. Thus we investigated here whether acute stroke might be associated with changes Read More

Thapsigargin is a pro-apoptotic chemical, which has been shown to be useful to study cell death of cholinergic or dopaminergic neurons, or cells, which degenerate in Alzheimer's disease or Parkinson's disease, respectively. The aim of the present work was to study the effects of thapsigargin in the well established organotypic brain co-slice model composed of the basal nucleus of Meynert (nBM), ventral mesencephalon (vMes Read More

That promising neuroprotectants failed to demonstrate benefit against stroke highlights the great difficulties to translate preclinical pharmacological effects in clinical outcomes. Part of this hurdle implies the complex response to injury of the neurovascular unit increasing the cerebrovascular permeability at the level of the blood-brain barrier (BBB). Previous studies reported neuroprotection in animal models u Read More

Sepsis is a major disease entity with important clinical implications. It is associated with a high mortality rate in humans. Recently, several studies have demonstrated that Intensive Care Unit survivors present long-term cognitive impairment, including alterations in memory, attention, concentration and/or global loss of cognitive function. The pathogenesis of septic encephalopathy and cognitive impairment are still poo Read More

A new nosologic vascular pattern that is defined by chronic cerebrospinal venous insufficiency (CCSVI) has been strongly associated with multiple sclerosis. The picture is characterized by significant obstacles of the main extracranial cerebrospinal veins, the jugular and the azygous system, and by the opening of substitute circles. The significance of collateral circle is still neglected. To the contrary, substitute circles are alternativ Read More
