INTRODUCTION Mild traumatic brain injury (MTBI) is a common neurological (neurotraumatological) diagnosis. As well as different subjective symptoms, many patients develop neuropsychological dysfunction with objective impairment of attention, memory and certain executive functions. Magnetic resonance imaging (MRI) is not routinely used in MTBI patients(More)
UNLABELLED Carpal tunnel syndrome (CTS) is the most common form of peripheral nerve entrapment. Electromyography with selected nerve conduction studies (NCS) is an accepted diagnostic tool in CTS patients. Ultrasonography presents a widely available and low cost investigation method and its position in CTS diagnostics needs further clarification with(More)
INTRODUCTION Mild traumatic brain injury (MTBI) is a common neurotraumatologic diagnosis. It is possible to confirm objective cognitive impairment in MTBI patients not only by complex neuropsychological testing but also by event-related potentials (ERPs). The most common ERPs used in clinical practice are based on an oddball paradigm. Magnetic resonance(More)
BACKGROUND Cardio-embolic etiology is the most frequently predicted cause of cryptogenic stroke/TIA. Detection of occult paroxysmal atrial fibrillation is crucial for selection of appropriate medication. METHODS Enrolment of eligible cryptogenic stroke and TIA patients began in 2014 and will continue until 2018. The patients undergo long-term (12 months)(More)
INTRODUCTION Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder primarily affecting upper and lower motor neurons. Due to relative fast progression of the disease, early diagnosis is essential. Proton magnetic resonance spectroscopy ((1)H-MRS) is used for objectivization of upper motor neuron (UMN) lesions. The aim of this study(More)
OBJECTIVES Fat tissue is an important endocrine organ that produces a number of hormones and cytokines (leptin, adiponectin, resistin, plasminogen activator inhibitor-1, Tumour necrosis factor TNF α) with essential roles in regulation of many physiological functions. METHODS We targeted implications of adipokines in ischemic stroke patients. Patients with(More)
Cerebrovascular disorders, particularly ischemic stroke, are one of the most common neurological disorders. High rates of overweight and obesity support an interest in the role of adipose tissue and adipose tissue releasing cytokines in inducing associated comorbidities. Adipokines can serve as a key messenger to central energy homeostasis and metabolic(More)
INTRODUCTION Standard brain magnetic resonance imaging (MRI) is typically normal in most patients after mild traumatic brain injury (MTBI). Proton magnetic resonance spectroscopy (¹H-MRS) is more sensitive to detect subtle post-traumatic changes. The aim of the study was to evaluate the clinical correlations of these changes in the acute phase (within 3(More)
Isolated from pigeon genome short (approximately 450 nucleotides) and long (approximately 8000 nucleotides) single-stranded DNA fragments containing prolonged (greater than or equal to 300 nucleotides) polydeoxyandenylic sequences have been studied. Based on the analysis carried out we come to the conclusion that for the pigeon genome the prolonged(More)
AIMS This study aimed to compare the efficacy and safety of heparin and nadroparin in order to provide an additional therapeutic option for patients with acute ischemic stroke in, whom systemic thrombolysis was excluded, or thrombectomy could not be performed. METHODS We describe a prospective randomized double-blind placebo-controlled pilot study in(More)
