Ammonia is a neurotoxin involved in the pathogenesis of neurological conditions associated with hyperammonemia, including hepatic encephalopathy, a condition associated with acute—(ALF) or chronic liver failure. This article reviews evidence that apart from directly affecting the metabolism and function of the central nervous system cells, ammonia(More)
Ammonia is responsible for cerebral edema associated with acute liver failure, but the role of the vasogenic mechanism has been a matter of dispute. Here, we tested the hypothesis that ammonia induces changes in blood-brain barrier (BBB) permeability by a mechanism coupled to oxidative/nitrosative stress (ONS) evoked in the BBB-forming cerebral capillary(More)
INTRODUCTION Giardia intestinalis is the most common intestinal protozoan parasite, which infects humans, dogs and other mammals throughout the world. So far eight genotypes of the parasite have been described of which four were found in dogs. Assemblages A-I and B infect either dogs or humans. Assemblages C and D occur only in dogs. The aim of the study(More)
BACKGROUND AND PURPOSE Disparities in resources, access to the expertise and healthcare providers both at hospital and before admission, or patients' awareness of stroke symptoms can cause differences in weekend and weekday stroke severity and prognosis. The aim of the study was to explore differences in baseline characteristics and outcomes of ischaemic(More)
UNLABELLED Stroke is a major global health problem. It is the third leading cause of death and the leading cause of adult disability. INTERHEART, a global case-control study of acute myocardial infarction in 52 countries (29,972 participants), identified nine modifiable risk factors that accounted for >90% of population-attributable risk. However,(More)
INTRODUCTION Neurodegeneration with brain iron accumulation (NBIA) comprises a heterogeneous group of disorders with accumulation of iron in the brain, mostly basal ganglia. NBIA subtype mitochondrial membrane protein-associated neurodegeneration (MPAN) is caused by recently discovered mutations in C19orf12, which encodes a protein localized in the(More)
BACKGROUND AND PURPOSE Significant intercenter variability in quality of care and stroke outcomes was found in many countries. The aim of the study was to compare the acute ischemic stroke care and outcomes in centers participating in the Polish National Stroke Prevention and Treatment Registry. METHODS The World Health Organization Stepwise Approach to(More)
BACKGROUND AND PURPOSE Little has been published about different elements of the health services in long-term follow-up in the countries of Central and Eastern Europe. The aim of this study was to explore the health services for stroke patients in Poland. MATERIAL AND METHODS Patients from 3 centres representing different levels of stroke care(More)
BACKGROUND AND PURPOSE A limitation when making early decisions on stroke management is the lack of rapid diagnostic and prognostic testing. Our study sought to identify peripheral blood RNA biomarkers associated with stroke. The secondary aims were to assess the discriminative capacity of RNA biomarkers for primary stroke type and stroke prognosis at(More)
BACKGROUND AND PURPOSE Stroke is a preventable disease and acute ischaemic stroke can be effectively treated. Specific pharmacotherapy is recommended in either prevention or acute ischemic stroke treatment. We aimed to evaluate the use and the early and late outcomes impact of drugs administered before and in acute ischaemic stroke in a real world practice.(More)
