Intravenous thrombolysis (IVT) is a standard treatment for anterior (ACS) and posterior circulation stroke (PCS). However, due to the low occurrence of PCS and of intracranial hemorrhage (ICH) in PCS, the knowledge about ICH predictors following IVT in PCS is sparse. Our aim was to identify predictors for ICH following IVT in PCS. The set consisted of 1281 consecutive ischemic stroke (IS) patients treated with IVT, out of which 158 (103 males; mean age 65.6 ± 12.3 years) had PCS. Collected data include baseline characteristics, common stroke risk factors, pre-medication, stroke severity, admission blood glucose level, blood pressure and treatment with intravenous antihypertensive therapy before and during IVT, occlusion of arteries, recanalization rate, time to treatment, and clinical outcome at day 90...

BACKGROUND: Spontaneous intracerebral haemorrhage (ICH) is a relatively common fatal disease, with an overall global incidence estimated at 24.6 per 100,000 person-years. Given the high degree of morbidity and mortality associated with ICH, therapies that may have neuroprotective effects are of increasing interest to clinicians. In this last context, cell therapies offer the promise of improving the disease course which cannot be addressed adequately by existing treatments. OBJECTIVE: The aim of this review is to evaluate the protective effects and molecular mechanisms of mesenchymal stem cells (MSCs) on haemorrhagic brain following ICH...

Hot-melt extrusion on co-rotating twin screw extruders is a focused technology for the production of pharmaceuticals in the context of Quality by Design. Since it is a continuous process, the potential for minimizing product quality fluctuation is enhanced. A typical application of hot-melt extrusion is the production of solid dispersions, where an active pharmaceutical ingredient (API) is distributed within a polymer matrix carrier. For this dosage form, the product quality is related amongst others to the drug content...

BACKGROUND: Current guidelines recommend that rapid systolic blood pressure (SBP) lowering to 140 mmHg may be considered in intracerebral hemorrhage (ICH) patients regardless of initial SBP. However, limited safety data exist in patients presenting with varying degrees of severe hypertension. The purpose of this study was to determine whether there was an increased risk of acute kidney injury (AKI) based upon degree of presentation hypertension in ICH patients whose blood pressure was reduced intensively...

During sprouting angiogenesis in the vertebrate vascular system, and primary branching in the Drosophila tracheal system, specialized tip cells direct branch outgrowth and network formation. When tip cells lumenize, they form subcellular (seamless) tubes. How these seamless tubes are made, shaped and maintained remains poorly understood. Here we characterize a Drosophila mutant called ichor (ich), and show that ich is essential for the integrity and shape of seamless tubes in tracheal terminal cells. We find that Ich regulates seamless tubulogenesis via its role in promoting the formation of a mature apical extracellular matrix (aECM) lining the lumen of the seamless tubes...
