Involvement of circulating microRNAs in the pathogenesis of atherosclerosis in young patients with obesity.

Obesity is considered an important factor contributing to the development of atherosclerosis. Inflammation plays a key role in endothelial dysfunction (ED), an initial stage of the atherosclerotic process. Several microRNAs (miRNAs) may play an important role in the inflammatory process, but there is a lack of information about their participation in the early stages of atherosclerosis development in patients with obesity.

Analysis of Cdx2 VDR gene polymorphism rs11568820 in association with multiple sclerosis in Slovaks.

Vitamin D deficiency is involved in the pathogenesis of multiple sclerosis (MS), a severe autoimmune demyelinating disease of the central nervous system. The gene polymorphism Cdx-2 (rs11568820, G/A) seriously influences the trancriptional activity of the vitamin D receptor (VDR) that binds the vitamin D responsive elements of target genes including HLA-DRB1*15. The aim of the present study in Slovaks was to analyse the association of Cdx-2 variants with the risk of MS and disability progression, and to assess the DRB1*15:01 allele as a possible confounding factor.

Neurocognitive performance in relapsing-remitting multiple sclerosis patients is associated with metabolic abnormalities of the thalamus but not the hippocampus- GABA-edited 1H MRS study.

Objectives: Multiple sclerosis (MS) is an inflammatory demyelinating disease that may cause physical disabling as well as cognitive dysfunction. The presented study investigated how the neuropsychological status depends on the thalamus and hippocampus's metabolic processes, using γ-aminobutyric acid-edited magnetic resonance spectroscopy (GABA-edited H MRS) in patients with early MS, and how the results differ from healthy volunteers.

Methods: We recruited 36 relapsing-remitting (RRMS) MS patients and 22 controls (CON).

Positivity of oligoclonal bands in the cerebrospinal fluid predisposed to metabolic changes and rearrangement of inhibitory/excitatory neurotransmitters in subcortical brain structures in multiple sclerosis.

Background: The latest diagnostic criteria for multiple sclerosis (MS) have revitalized the role of oligoclonal bands synthesis in the cerebrospinal fluid (CSF-OCB). This study identifies predictors of CSF-OCB-positivity among in vivo metabolic markers in the subcortical gray/white matter in MS patients after their first episode (CIS) and in patients with relapsing-remitting course (RRMS).

Methods: The study enrolled 13 CIS and 23 RRMS patients.

Early cardiac injury in acute respiratory distress syndrome: comparison of two experimental models.

Acute respiratory distress syndrome (ARDS) is characterized by diffuse lung damage, inflammation, oedema formation, and surfactant dysfunction leading to hypoxemia. Severe ARDS can accelerate the injury of other organs, worsening the patient´s status. There is an evidence that the lung tissue injury affects the right heart function causing cor pulmonale.

Altered hypothalamic metabolism in early multiple sclerosis - MR spectroscopy study.

Multiple sclerosis (MS) is a disease characterized by overlapping processes of neuroinflammation and neuro-axonal degeneration. Disturbances of the hypothalamo-pituitary axis in MS are supposed to modulate neuroinflammatory circuits, however, there is insufficient knowledge about the hypothalamic metabolism alterations in early MS. This H MRS study performed on a 1.

Titanium dioxide (TiO) has been vastly used commercially, especially as white pigment in paints, colorants, plastics, coatings, cosmetics. Certain industrial uses TiO in diameter <100 nm. There are three common exposure routes for TiO: (i) inhalation exposure, (ii) exposure via gastrointestinal tract, (iii) dermal exposure.

TNFRSF1A polymorphisms and their role in multiple sclerosis susceptibility and severity in the Slovak population.

Tumour necrosis factor (TNF)-mediated signalling plays a key role in inflammatory and neurodegenerative processes leading to the development of multiple sclerosis (MS). Recent studies have highlighted the role of tumour necrosis factor receptor superfamily member 1A (TNFRSF1A) gene encoding the type 1 TNF receptor in the genetic predisposition to MS. This study aimed to validate the association of TNFRSF1A rs1800693 and rs4149584 polymorphisms with susceptibility to MS in the Slovak population and analyse their influence on age at disease onset, severity, and disability progression.

NMR metabolomic study of blood plasma in ischemic and ischemically preconditioned rats: an increased level of ketone bodies and decreased content of glycolytic products 24 h after global cerebral ischemia.

Cardiac arrest is one of the leading causes of death among adults in older age. Understanding mechanisms how organism responds to ischemia at global level is essential for the prevention and ischemic patient's treatment. In this study, we used a global cerebral ischemia induced by four-vessel occlusion as an established animal model for ischemic stroke to investigate metabolic changes after 24 h reperfusion, when transitions occur due to the onset of delayed neuronal death.

Objective: The aim of our present study was to analyse the association of HLA-DRB1 and -DQB1 alleles and genotypes with Multiple Sclerosis (MS) disability progression in a cohort of Central European Slovak population.

Methods: The allele and genotype variants were analyzed in 282 non-related MS patients. Rate of disease disability progression was evaluated using EDSS score in the 5, 7, 10, and 15 year of disease duration, time to reach EDSS score 3 and 5, and MSSS score.

The age at onset in Multiple Sclerosis is associated with patient's prognosis.

Background: The causes of the individual differences in the rate of disability progression in multiple sclerosis (MS) are still not completely clear. According to the long-term prognosis of MS patients, the search for new valuable prognostic markers of "benign" or "malign" MS is necessary.

Objectives: Our aim was to assess the possible association of MS onset age with the disease disability progression rate in Slovak patients with MS.

Anaplastic astrocytoma mimicking progressive multifocal leucoencephalopathy: a case report and review of the overlapping syndromes.

Background: Co-occurrence of multiple sclerosis (MS) and glial tumours (GT) is uncommon although occasionally reported in medical literature. Interpreting the overlapping radiologic and clinical characteristics of glial tumours, MS lesions, and progressive multifocal leukoencephalopathy (PML) can be a significant diagnostic challenge.

Case Presentation: We report a case of anaplastic astrocytoma mimicking PML in a 27-year-old patient with a 15-year history of MS.

Aim: To test the association between common TP53 haplotypes and colorectal cancer (CRC) development.

Patients And Methods: A total of 277 CRC patients and 167 healthy volunteers were included in the study. Common TP53 haplotypes were estimated from eight single-nucleotide polymorphisms (SNPs) (rs1614984, rs77697176, rs12947788, rs1800372, rs2909430, rs1042522, rs17878362 and rs11652704).

Hypothalamic damage in multiple sclerosis correlates with disease activity, disability, depression, and fatigue.

Objectives: Disturbances in the hypothalamo-pituitary axis are supposed to modulate activity of multiple sclerosis (MS). We hypothesised that the extent of HYP damage may determine severity of MS and may be associated with the disease evolution. We suggested fatigue and depression may depend on the degree of damage of the area.

Analysis of ICAM1 gene polymorphism in Slovak multiple sclerosis patients.

Infiltration of immune cells into CNS is one of the essential events in multiple sclerosis (MS) development. Adhesion molecules like the intercellular adhesion molecule 1 (ICAM-1) play critical role in this process. Therefore, the ICAM1 gene containing two important single-nucleotide polymorphisms (SNPs) belongs to candidate loci with possible involvement in MS susceptibility and/or severity.

Lung inflammatory and oxidative alterations after exogenous surfactant therapy fortified with budesonide in rabbit model of meconium aspiration syndrome.
