None of the vascular emergency diagnostic methods commonly used in the case of acute ischemic stroke, i. e. CTA, color-coded duplex sonography (CCDS), MRA, and DSA, is free of restrictions due to physical and physiological characteristics. As a result, misleading results initiating an inappropriate acute therapeutic intervention or hampering a ...

Post-stroke inflammation may induce upregulation of the kynurenine (KYN) pathway for tryptophan (TRP) oxidation, resulting in neuroprotective (kynurenic acid, KA) and neurotoxic metabolites (3-hydroxyanthranillic acid, 3-HAA). We investigated whether activity of the kynurenine pathway in acute ischemic stroke is related to initial stroke severity, long-term stroke outcome and the ischemia-induced ...

To date there is no diagnostic biomarker for mild stroke, although elevation of inflammatory biomarkers has been reported at early stages. Previous studies implicated acetylcholinesterase (AChE) involvement in stroke, and circulating AChE activity reflects inflammatory response, since acetylcholine suppresses inflammation. Therefore, carriers of polymorphisms that modify cholinergic activity should be ...

Multicomponent dietary weight loss supplements comprise the single largest segment of herbal preparations available to the public. As a result of limited de novo regulatory oversight, supplement-related adverse events are underreported secondary to the lack of adequate pharmacodynamic, pharmacokinetic, and clinical data. Here we report the case of an obese ...

The most common neurological manifestations of antiphospholipid syndrome (APS) in all age-groups include stroke and transient ischemic attacks due to arterial thromboses and cerebral ischemia. Antiphospholipid antibodies may cause additional non-criteria neurological impairments through vascular, neuroinflammatory and direct neuronal effects. Anti-aggregant or anticoagulant therapies are indicated for APS-related ischemic strokes. ...

BACKGROUND: Despite t-PA proven benefits related to vessel reopening, up to 13% of stroke patients suffer reocclusions after t-PA. We aimed to analyze whether a functional polymorphism in a fibrinolysis inhibitor gene [plasminogen activator inhibitor-1 (PAI-1)] might be associated with reocclusion rates after stroke thrombolytic therapy. METHODS: 165 patients with ...
