AB  - Introduction Disruption of copper homeostasis and dysfunction of mitochondria have been documented in sclerotic hippocampi (HS) of patients with mesial temporal lobe epilepsy (mTLE). However, a potential link between these pathological changes has not been tackled so far. Herein, we analyzed regional distribution of neuron somata density, copper concentration, and the activity of cytochrome c oxidase (CCO), a component of mitochondrial electron transport chain and copper-containing metalloprotein, in HS. Methods Histochemical staining and laser ablation inductively coupled plasma mass spectrometry were carried out to construct comparable maps of these parameters in coronal sections of hippocampi of 3 mTLE-HS patients and 3 control subjects. Results Copper levels were decreased in all regions of HS with pyramidal neuron somata. CCO activity was significantly reduced in stratum pyramidale (PY) 1 and cornu Ammonis field 4, the two regions with significant reduction in neuron somata density. CCO activity was also lower in layers that contain apical dendrites of pyramidal neurons and mossy fibers. It appears that copper deficiency in PY2 and PY3 comes before CCO activity reduction and neuronal loss. A strong positive correlation was found between neuron density, Cu concentration, and CCO activity. Conclusions Presented results imply that pathological alterations in Cu and energy metabolism could be involved in the development of HS. A limitation of this study was the relatively small number of patients. However, presented results underline copper deficiency as a component of pathological mechanisms of epilepsy and warrant further investigation of cuproproteins and members of copper transport machinery.

AB  - IntroductionAny substance that induces production of free radicals can be a potential cause of brain damage. The aim of our study was to investigate the relationship between some metal ions and oxidative stress biomarkers in the blood of patients with brain tumor and hydrocephalus.Material and methodsOur study included 27 control subjects, 24 patients with brain tumor and 21 patients with hydrocephalus. The activities of superoxide dismutase (CuZn SOD), catalase (CAT), glutathione peroxidase (GSH-Px), glutathione reductase (GR), glutathione S-transferase (GST) and acetyl cholinesterase (AChE), as well as concentrations of reduced glutathione (GSH), lipid peroxides (TBARS) and sulfhydryl groups (SH) were analyzed in the plasma and red blood cells (RBCs) of patients. We also determined the concentrations of Mn, Ni, Co, Cu, Zn, As, Se, Cd, Hg and Fe.ResultsThe higher activity of SOD and concentration of GSH in both investigated groups could indicate higher oxidative stress. We also observed decreased levels of SH groups in both groups of patients. In both groups of patients we detected decreased concentrations of Ni, Co, Zn and Fe (and Mn in brain tumor patients) and increased concentrations of As, Se and Cd in the blood. Interestingly, we observed a higher concentration of Cd in both plasma and RBCs of hydrocephalus patients compared to the patients with brain tumor.ConclusionsThere are strong correlations between some metal ion concentrations and certain oxidative stress biomarkers in the blood of patients, which supports our hypothesis, but the observed trend needs to be further investigated.

AB  - More and more studies are identifying the regulation of metal homeostasis as one of the key points of central nervous system’s
well-being. Epilepsy is a particularly interesting neurological condition when viewed in terms of the correlation between the
amount of metals and the development of a seizure. This lecture will present contribution of our group to the field of metal
biology in epilepsy by mapping brain metals in sclerotic hippocampus resected from drug resistant mesial temporal lobe
epilepsy (mTLE) patients as surgical therapeutic approach. Direct insight into this epileptogenic area, by two powerful techniques,
optical emission and mass spectrometry, has led us to investigation of copper turnover. Namely, among the examined metals,
we found the deficiency of copper in sclerotic hippocampus on two levels: (i) in whole structure (ii) and locally in the areas of
neuronal loss, with significant correlation between copper concentration and neuron density. Furthermore, analysis of copper
metalloproteins showed: (i) significant increase or decrease in levels of protein that is participating in copper transport into
the cell (CTR1) depending on the degree of hippocampal neuronal loss; (ii) and lower activity of an enzyme in which copper
is part of the active site, cytochrome c oxidase, in sclerotic hippocampi of patients compared to control tissue. In our further
investigations it remained to be determined whether changes in copper concentrations and copper metalloproteins are causal
to pathology of mTLE or they represent epiphenomenon.

AB  - Aims: A drop in copper level and the loss of energy homeostasis are both portrayed in mesial temporal lobe epilepsy (mTLE) with hippocampal sclerosis (HS) patients. Cytochrome c oxidase (COX) represents a crossroad of energy and copper metabolism; it is a key component of mitochondrial machinery and contains two copper centers. Our aim here was to examine the link between COX activity and the copper transporting system in HS. COX activity and the levels of mRNA of selected chaperones - COX11, COX17, Sco1 and Sco2 were determined in 13 anatomically distinct hippocampal regions. Methods: Study was performed on seven hippocampal samples, four of which had been acquired during the course of amygdalohippocampectomy treatment of medically intractable epilepsy and three control postmortem samples. Adjacent slices were used for Nissl staining, COX activity assay and mRNA in situ hybridization with autoradiography. Densitometry was performed using ImageJ. Results: Overall COX activity was decreased in HS compared to controls (P = 0.0003). However, 5 regions showed significantly lower COX activity in HS and 8 did not. Subiculum showed slightly higher activity in HS. The levels of mRNA levels were lowered in HS in 6 regions for COX11, 10 regions for COX17, two regions for Sco1 and 11 regions for Sco2. Conclusions: Our findings suggest the loss of energy homeostasis in HS may be related to pathological changes in specific components of copper delivery to COX, and that the impact may vary between different hippocampal regions.

AB  - Mesial temporal lobe epilepsy associated with hippocampal sclerosis (mTLE-HS) is probably the single most frequent human focal epilepsy. The involvement of redox processes in the pathological mechanisms of mTLE-HS has been implicated  by mitochondrial dysfunction and oxidative damage, and by different metabolic abnormalities that have been observed in sclerotic hippocampi, such as altered metabolism of redox-active metals. The strongest proof came with the analysis of enzymatic antioxidative system. Sclerotic hippocampi show drastically increased activity and levels of hydrogen peroxide–removing enzymes – catalase and glutathione peroxidase/reductase. Catalase is located mainly in neurons in both, controls and HS. Sclerotic hippocampi are depleted of glutathione peroxidase-positive blood vessels that are present in control hippocampi. Pertinent to this, it has been documented that hippocampi of mTLE-HS patients show increased blood vessel density, but most of the vessels represent atrophic vascular structures. On the other hand, HS showes specific glutathione peroxidase-rich loci that are present in gyrus dentatus, CA regions, and alveus, and appear to represent bundles of astrocytes. These loci are probably sites of excessive (neuronal) production of hydrogen peroxide that is counteracted by astrocytes. Finally, protein levels of mitochondrial enzyme manganese superoxide dismutase are higher in HS than controls. Neurons with abnormal morphology and strong superoxide dismutase immunofluorescence are present in all neuronal layers in HS. In close, antioxidative system is upregulated in HS implying that epileptogenic hippocampi are exposed to oxidative stress. The involvement of redox alterations in the pathology of epilepsy may open new pharmacologic perspectives for mTLE-HS treatment.

AB  - Introduction
Any substance that induces production of free radicals can be a potential cause of brain damage. The aim of our study was to investigate the relationship between some metal ions and oxidative stress biomarkers in the blood of patients with brain tumor and hydrocephalus.

Material and methods
Our study included 27 control subjects, 24 patients with brain tumor and 21 patients with hydrocephalus. The activities of superoxide dismutase (CuZn SOD), catalase (CAT), glutathione peroxidase (GSH-Px), glutathione reductase (GR), glutathione S-transferase (GST) and acetyl cholinesterase (AChE), as well as concentrations of reduced glutathione (GSH), lipid peroxides (TBARS) and sulfhydryl groups (SH) were analyzed in the plasma and red blood cells (RBCs) of patients. We also determined the concentrations of Mn, Ni, Co, Cu, Zn, As, Se, Cd, Hg and Fe.

Results
The higher activity of SOD and concentration of GSH in both investigated groups could indicate higher oxidative stress. We also observed decreased levels of SH groups in both groups of patients. In both groups of patients we detected decreased concentrations of Ni, Co, Zn and Fe (and Mn in brain tumor patients) and increased concentrations of As, Se and Cd in the blood. Interestingly, we observed a higher concentration of Cd in both plasma and RBCs of hydrocephalus patients compared to the patients with brain tumor.

Conclusions
There are strong correlations between some metal ion concentrations and certain oxidative stress biomarkers in the blood of patients, which supports our hypothesis, but the observed trend needs to be further investigated.

AB  - The accumulating evidence on the relation between the disturbed metal homeostasis
and epilepsy urges the need for data regarding the total metal concentrations, as well
as metal distribution in the brain itself, in order to indicate where to direct the
potential therapy, to metal supplementation or chelation. This paper summarizes our
results on the measurements of some important essential metals in hippocampi of
patients with mesial temporal lobe epilepsy (mTLE) who underwent
amigdalohippocampectomy. The key findings point out that levels of copper and
manganese are deficient in hippocampi of mTLE patients, and that their
concentrations correlated positively with neuronal loss in affected regions of sclerotic
hippocampus. In addition, the Cu concentration was decreased in the areas of total
neuronal loss. Iron and zinc total hippocampal levels were neither accumulated nor
deficient compared to control. Our results contribute to deeper insight of metals
biology in the epilepsy and may represent the initial point of new and non-invasive
therapy of drug resistant epilepsy.

AB  - The monitoring of progression in amyotrophic lateral sclerosis (ALS) relies on clinical outcome measures that take months to interpret, such as revised ALS functional rating scale (ALSFRS-R) score, with no approved biomarkers. A number of clinical studies have documented the involvement of oxidative stress in ALS pathology. Pertinent to this, we propose to evaluate oxidation-reduction potential (ORP) of cerebrospinal fluid (CSF) as a potential indicator of ALS progression. The case-control study included 24 patients with neurological non-neurodegenerative disorders (controls) and 82 ALS patients with different degrees of disease (ALSFRS-R score: 21-47). ORP was significantly higher in ALS patients than controls. It was not dependent on age or gender. A strong negative correlation was found between ORP and ALSFRS-R score for all patients and patients with spinal onset. In other words, ORP increased with ALS progression. No correlation was found for the subset of patients with bulbar onset, most likely because of the physical distance between neurodegenerative loci and the site of CSF collection. These results lead to the hypothesis that ORP of CSF has a potential as monitoring biomarker in ALS, particularly in the cohort of patients with spinal onset. Antioxid. Redox Signal. 28, 1570-1575.

AB  - The loss of metal homeostasis has been implicated in the pathophysiology of mesial temporal lobe epilepsy associated with hippocampal sclerosis (mTLE-HS). Here we applied laser ablation inductively coupled plasma mass spectrometry imaging to establish the spatial distribution of Zn, Fe, Cu and Mn in coronal sections of hippocampi of four patients with drug-resistant mTLE-HS who underwent amygdalohippocampectomy. Detailed maps of the metal concentrations in the different morphological areas/layers were built and analyzed. The highest level of Zn (>20 μg g(-1)) was found in mossy fiber-rich regions - cornu ammonis field 4 (CA4), gyrus dentatus, and CA3. The distribution of Fe appears to reflect the routes of the main intrahippocampal blood vessels. The highest concentrations of Cu (>10 μg g(-1)) and Mn (>15 μg g(-1)) were observed in regions/layers with neuron somata - subiculum, CA4, gyrus dentatus, and stratum pyramidale (SPy) in CA1 and CA2. Alveus and other regions with axons and dendrites generally showed lower levels of Zn, Cu, and Mn. The Cu concentration was decreased in the areas of total neuronal loss in SPy in CA1 (9.73 ± 0.91 μg g(-1)), compared to the subiculum (13.32 ± 1.29 μg g(-1); p = 0.043). The Cu and Mn concentrations correlated positively with neuron density in the SPy in CA1 (R = 0.629, p < 0.001; and R = 0.391, p = 0.004). These results provide a deeper insight into hippocampal metabolism of metals, and pave the road for identifying the components of the mechanism of epileptogenesis among Cu and Mn transporters and metalloproteins.
