Activity of exoglycosidases in blood, urine, cerebrospinal fluid, and vitreous humor in individuals who died from ethyl alcohol poisoning.

Lysosomal exoglycosidases, namely α-mannosidase (MAN), α-fucosidase (FUC), β-galactosidase (GAL), and β-glucuronidase (GLU), are of crucial importance in breaking down the oligosaccharide chains of multiple glycoconjugates. Those enzymes liberate monosaccharides from non-reducing ends of oligosaccharide chains. In this study, we have aimed to assess the potential utility of MAN, FUC, GAL, and GLU activities as indicators of ethanol abuse in individuals who died from ethanol intoxication, while also investigating the mechanisms underlying their deaths.

Healthy Food Pyramid as Well as Physical and Mental Activity in the Prevention of Alzheimer's Disease.

The ageing of the population is resulting in neurodegenerative diseases, including Alzheimer's disease (AD), which are an increasing social, economic and medical problem. Diet and physical activity are now considered as important modifiable factors that help prevent or delay the development of AD and other dementia-related diseases. The pyramid of healthy nutrition and lifestyle is a way of presenting the principles, the implementation of which gives a chance for proper development and a long healthy life.

Effect of Lipopolysaccharide-Induced Inflammatory Challenge on β-Glucuronidase Activity and the Concentration of Quercetin and Its Metabolites in the Choroid Plexus, Blood Plasma and Cerebrospinal Fluid.

Quercetin-3-glucuronide (Q3GA), the main phase II metabolite of quercetin (Q) in human plasma, is considered to be a more stable form of Q for transport with the bloodstream to tissues, where it can be potentially deconjugated by β-glucuronidase (β-Gluc) to Q aglycone, which easily enters the brain. This study evaluates the effect of lipopolysaccharide (LPS)-induced acute inflammation on β-Gluc gene expression in the choroid plexus (ChP) and its activity in blood plasma, ChP and cerebrospinal fluid (CSF), and the concentration of Q and its phase II metabolites in blood plasma and CSF. Studies were performed on saline- and LPS-treated adult ewes ( = 40) receiving Q3GA intravenously ( = 16) and on primary rat ChP epithelial cells and human ChP epithelial papilloma cells.

Potential Role of L-Carnitine in Autism Spectrum Disorder.

L-carnitine plays an important role in the functioning of the central nervous system, and especially in the mitochondrial metabolism of fatty acids. Altered carnitine metabolism, abnormal fatty acid metabolism in patients with autism spectrum disorder (ASD) has been documented. ASD is a complex heterogeneous neurodevelopmental condition that is usually diagnosed in early childhood.

Salivary Biomarkers of Stress, Anxiety and Depression.

Stress, anxiety and depressive disorders are often characterized by the activation of the stress axis, which results in similar symptoms at some point in these disorders. These disorders are closely related to each other-they occur simultaneously or follow one another. The diagnosis of stress, anxiety and depression is not a perfect procedure currently-it is based on patient observation and an interview with the patient and their family.
