AB  - In this work we have characterized and compared chitin sourced from exoskeleton of Tenebrio molitor larvae fed with polystyrene or plastic kitchen wrap combined with bran in the ratio 1:1 with chitin sourced from larvae exoskeleton fed only with bran. Analysis of the frass by ATR-FTIR showed very similar spectra and confirmed degradation of the plastic feed components, while ATR-FTIR analysis of the exoskeleton verified the absence of any plastic residue. Deproteinization followed by demineralization produced 6.78 -5.29 % chitin, showing that plastic (polystyrene or plastic kitchen wrap) in the larvae diet resulted in heavier insect exoskeleton, but yielded slightly less chitin, with the lowest value obtained for plastic kitchen wrap in the insect diet. The deacetylation degree of 98.17-98.61% was determined from measured ATR-FTIR spectra. XRD analysis confirmed the presence of -chitin with a crystallinity index of 66.5-62% and crystallite size 4-5 nm. Thermogravimetric analysis showed similar degradation curves for all chitin samples, with two degradation steps. These results show that chitin sourced from exoskeleton of T. molitor larvae fed with plastic (polystyrene or plastic kitchen wrap) and contributing to significant biodegradation of major polluting materials can be a feasible and alternative source of chitin, further promoting a bio-circular economy.

AB  - In this study, the concentrations of metals and trace elements (As, Cd, Co, Cr, Cu, Hg, Ni,
Pb and Zn) were determined in the muscle tissue of adult roach and white bream at two different
sites in the Belgrade section of the Danube. Twenty-six fatty acids, consisting of nine saturated FA
(SFAs), seven monosaturated FA (MUFAs) and ten polysaturated FA (PUFAs), were identified. The
analysis of the concentration of metals and trace elements of the roach and white bream showed
species-specific differences in their bioaccumulation. Four of all elements analyzed (As, Hg, Ni and
Pb) correlated significantly with the changes in FA profiles in fish from both sampling sites, with the
exception of Cu, which correlated with the FA profile at the site before, and Zn, whose concentration
influenced the FA profile at the site after wastewater discharges. The lower PUFA content in the fish
from a site under higher environment pressure could indicate that the fish are stressed. The results
suggest that changes in lipid composition may be one of the protective mechanisms of cells to cope
with anthropogenic stressors.

AB  - The success of patch-clamp giga-ohm seal formation on filamentous fungi Phycomyces blakesleeanus protoplasts was investigated to evaluate their usefulness in ion channel studies on filamentous fungi. Protoplasts were obtained by laser-mediated nanosurgery of the cell wall stained with Calcofluor White. To enable a successful seal formation, it is critical to prevent cell wall regeneration. Since wall integrity responses in fungi involve kinase-dependent pathways, we aimed to sufficiently reduce intracellular ATP availability using the respiratory inhibitor azide. The effect of azide on phosphate metabolites of Phycomyces blakesleeanus, as determined by 31P NMR spectroscopy, was a reduction in intracellular ATP accompanied by a decrease in long chain polyphosphates. Subsequently, all seal formation measurements were performed in the presence of azide, and protoplast viability was confirmed by cytoplasmic streaming. The success of seal formation depends on the size of the protoplasts, as larger protoplasts are more prone to successful seal formation. It was also found that the laser power used in nanosurgery could influence the success of seal formation, as higher values were associated with a lower success rate. The protoplasts released by laser nanosurgery produced by our newly developed method are a good model system for patch clamp on filamentous fungal membranes because their plasma membrane can easily form high-quality seals with the patch pipette.

AB  - Adaptive changes in mitochondrial morphology are associated with changes in the mitochondrial function and metabolic fitness of eukaryotic cells. We previously described in young hyphae of the filamentous fungus Phycomyces blakesleeanus a dramatic effect of an increase in ambient temperature during growth: a 3°C warmer environment compared with a control temperature of 22°C resulted in the appearance of long elongated (“tubular”) mitochondria accompanied by an increase in lipid droplet density. Here, we examined how cooler ambient temperature (18°C) during growth affects mitochondrial morphology in P. blakesleeanus compared with the control grown at 22°C. We used two-photon fluorescence imaging (TPEF) of live hyphae stained with the vital mitochondrial dye rhodamine 123. Extraction of relevant parameters (number, size, and shape of mitochondria) from TPEF images was performed using the Ilastik machine learning-based software. The suitability of the Ilastik analysis was compared with the Particle Analysis (ImageJ). Cold treatment resulted in the appearance of tubular mitochondrial morphology that was absent in the control group. Tubular mitochondrial morphology appears to be an adaptive feature that occurs in both warmer and colder conditions and is likely part of the stress response.

AB  - Mitochondrial function, and consequently cellular metabolic status and fitness of a cell, is tightly linked
to the dynamic changes of mitochondrial morphology, including mitochondrial fusion, fission and
mitophagy [1]. Lipid droplets (LDs) can be in close contact with mitochondria, and accumulate
autophagy or mitophagy generated material during the reparatory processes [2]. The effect of increased
ambient temperature on mitochondrial morphology and LDs density in living cells of the filamentous
fungus Phycomyces blakesleeanus was investigated. For in vivo imaging of mitochondria and LDs
multiphoton microscopy was used. Multiphoton microscopy enables 3D imaging in high resolution and
reduced photodamage and photobleaching of the sample using IR ultrafast pulsed lasers. Mitochondria
were stained with the vital dye Rhodamine123 (Rh123) which enters these organelles based on their
membrane potential - mitochondria must be healthy/active to stain. A wavelength of 800 nm from Ti:Sa
laser (160 fs pulse duration, 76 MHz repetition rate) was used for two-photon excitation of Rh123. The
laser beam was focused by the Zeiss Plan Neofluar 40x1.3 objective lens and the signal was detected
through a bandpass interference filter MF530/43 (ThorLabs, USA). For LDs staining a Nile Red dye
was used and excited by Yb: KGW laser at 1040 nm [3]. Six morphological types of mitochondria were
observed in the hyphae of this fungus: intermediate type - normal, intermediate with small semicircular
tubules, tubular, elongated tubular, fragmented (small ellipsoid tubule) and fragmented with exclusively
spheroid-shaped mitochondria. Changes in mitochondrial morphology were induced by a small
temperature change. A 3°C increase in ambient temperature, from 22°C, had a dramatic effect on
mitochondrial morphology, inducing the appearance of a predominantly tubular mitochondrial
morphology. The total area percentage of mitochondria showed an increasing trend when grown at
25°C. Increasing the ambient temperature to 25°C induced a statistically significant increase in the
percentage of hyphal area occupied by LDs from 2.9 ± 1.6 to 4.7 ± 2.2 (mean value and SD in percentage
of hyphal area). The observed response to the small temperature increase points to the physiological
adaptation of hyphal metabolism.

AB  - Insulin resistance is a state where a normal amount of insulin can’t provoke an appropriate metabolic response. Insulin promotes membrane trafficking of the glucose transporter GLUT4 from the storage vesicles to the plasma membrane in white adipose tissue. Adipocytes use glucose for lipogenesis and store the energy as lipid droplets. If adipocytes are unable to uptake glucose, a chronic state of hyperglycemia is developed, with severe health consequences. Polyphenols are natural anti-inflammatory and antioxidant agents. Food rich in polyphenols has been suggested to exert an ameliorative effect on restoring insulin sensitivity, with the main identified target being AMPK1,2, one of the key sensors of intracellular energy. Here, we tested the effect of methanol extracts from three newly introduced strawberry (Fragaria x ananassa, Duch.) cultivars – 'Aprika', 'Sandra' and 'Quicky' on glucose metabolism in 3T3-F442A adipocytes. It was determined that 'Aprika' has the highest total phenolic content, relative to the other two cultivars. After 72-h exposure, none of the strawberry cultivars affected adipocyte cell growth significantly. Protein expression analysis of the differentiated adipocytes suggested 'Aprika', but not the other two cultivars, significantly increased the AMPK expression, as well as GLUT4, thus increasing glucose uptake. Strawberry extracts did not significantly affect the differentiation of adipocytes (SIRT1 and PPARγ), nor the fatty acid synthesis (ACC). Conclusively, the 'Aprika' methanol extract with high phenolic content exerts an ameliorative effect on glucose uptake, presumably through activation of the AMPK-dependent mechanism of GLUT4 trafficking. The systemic effects of the ‘Aprika’ cultivar should be further investigated. Implications of the research are decreased hyperglycemia in obese and diabetic patients, by the introduction of the 'Aprika' strawberry cultivar into everyday diet. References 1.

AB  - The stomach content of 277 Amur sleeper individuals has been analyzed to present its feeding habits. Fish were sampled using electrofishing from July to November 2017 in the Danube River drainage channel near Veliko Gradište (Serbia). Fish age was estimated by otoliths examination. Ingested prey organisms were identified to the lowest reliable taxonomic level. The biotic indices: vacuity index (VI), frequency of occurrence (F), abundance (Cn), index of importance (PV), Shannon’s diversity index (H’), and equitability index (Eh) were calculated. A total of 18 prey categories and 1144 individual prey were identified in the fish diet, dominantly aquatic macroinvertebrates. There were no significant difference in diet composition between sampling months as well as 0+, 1+, and 2+ age groups (both 3+ and 4+ had one individual). Only eight individuals were found with empty intestines, thus VI was low (2.9). In average, each fish had 4.1 prey items in their intestines. For whole sample, H′ was 1.84 and Eh was 0.64. Trichoptera, Ephemeroptera, and Gastropoda were the most frequent, dominant, and abundant. The greatest diversity of prey items was recorded for fish sampled in October as well as for 2+ individuals, and the lowest for fish from August and 0+ individuals.

AB  - Pikeperch of age classes 3+ and 4+ were collected from the Garaši reservoir (Serbia)
to analyze their bioindicator potential and compare their possible differences. Concentrations of
26 elements were determined in gills, muscles, and liver by inductively-coupled plasma optical
emission spectrometry (ICP-OES) and of 17 organochlorine pesticides (OCPs), and six polychlorinated
biphenyls (PCBs) in muscle by gas chromatography with mass spectrometric detection (GC-MS).
Histopathological changes in the liver and gills were analyzed as biomarkers of general fish health.
Only the concentrations of Cd, Na, and P in the muscles differed significantly. The OCPs and
PCBs concentrations were below the detection limits, so fish meat consumption does not pose a risk
concerning these substances. Hg and Cd exceeded the maximum allowed concentrations in some
4+ individuals, probably due to biomagnification. Gills were the most affected by metal exposure in
both age classes. Histopathological changes and indices were minor and did not differ significantly
between age classes, suggesting that pollution did not affect the morphology and structure of gills and
liver. There were no significant correlations between elemental accumulation and fish condition or
between histopathological scores. Therefore, both age classes can be used as bioindicators of pollution.

AB  - In multiple sclerosis (MS), glial cells astrocytes interact with the autoreactive immune
cells that attack the central nervous system (CNS), which causes and sustains neuroinflammation.
However, little is known about the direct interaction between these cells when they are in close
proximity in the inflamed CNS. By using an experimental autoimmune encephalomyelitis (EAE)
model of MS, we previously found that in the proximity of autoreactive CNS-infiltrated immune cells
(CNS-IICs), astrocytes respond with a rapid calcium increase that is mediated by the autocrine P2X7
receptor (P2X7R) activation. We now reveal that the mechanisms regulating this direct interaction
of astrocytes and CNS-IICs involve the coupling between P2X7R, connexin-43, and β3-integrin. We
found that P2X7R and astroglial connexin-43 interact and concentrate in the immediate proximity of
the CNS-IICs in EAE. P2X7R also interacts with β3-integrin, and the block of astroglial αvβ3-integrin
reduces the P2X7R-dependent calcium response of astrocytes upon encountering CNS-IICs. This
interaction was dependent on astroglial mitochondrial activity, which regulated the ATP-driven
P2X7R activation and facilitated the termination of the astrocytic calcium response evoked by CNS-
IICs. By further defining the interactions between the CNS and the immune system, our findings
provide a novel perspective toward expanding integrin-targeting therapeutic approaches for MS
treatment by controlling the cell–cell interactions between astrocytes and CNS-IICs.

AB  - Astrocytes form a dense meshwork throughout the central nervous system (CNS) which qualifies them to perform interactive maintenance functions with neighboring cells. In neuroinflammation, this astroglial cell-to-cell interaction varies which can either promote or lessen pathological processes (1,2). In multiple sclerosis (MS), astrocytes engage in an interaction with immune cells which drives neurodegeneration by creating and sustaining an inflammatory CNS environment (3). Previously, we showed that CNS-infiltrated immune cells (CNS-IICs) in the experimental autoimmune encephalomyelitis (EAE) rat, rapidly alter the activity pattern of astrocytes by activating glial P2X7 receptor (P2X7R)(4). In the present study, we aimed to identify the properties of astroglial P2X7R in EAE and to identify mechanisms responsible for astrocyte activation in the presence of CNS-IICs (CD4+ T cells). In this respect, spinal cords from rats at the peak of EAE and age-matched healthy controls were isolated and protein expression of P2X7R and connexin-43 (Cx-43) were investigated. P2X7R protein expression was decreased in the lumbar spinal cord, while Cx-43 did not change. Next, we found that P2X7R and Cx-43 proteins interact in the lumbar spinal cord since both the monomer and the dimer Cx-43 co-immunoprecipitate with P2X7R. Even though the colocalization of P2X7R and Cx-43 was decreased in EAE compared to the control, the analysis of the distribution of astroglial P2X7R and Cx-43 and their colocalization in the radius of 20 μm from the infiltrated CD4+ T cell center showed that astroglial P2X7R and Cx-43 are specifically associated and concentrated in the proximity of CNS-IICs in the EAE spinal cord. Subsequently, to achieve an unambiguous analysis of astrocyte-immune cell interaction, we monitored Ca2+
dynamics in Fluo-4 labeled cultured naïve astrocytes following brief bath-application of CNS-IICs isolated and purified from spinal cords of EAE rats. Our data suggest that astroglial αvβ3-integrin acted upstream of P2X7R activation and is likely involved in establishing initial contact of astrocytes with CNS-IICs since astrocytic αvβ3-integrin block reduced the astrocytic Ca2+ response to CNS-IIC application. Furthermore, astrocytes challenged with CGP31157 (blocker of mNCLX and HCX) exhibited a prolonged intracellular Ca2+ elevation and higher ATP release after brief exposure to CNS-IICs, indicating a regulatory function of mitochondria on this intracellular astrocyte Ca2+ response. Collectively
these data describing integrin-relevant cellular mechanisms of astroglial P2X7R activation could help to expand integrin-inhibiting therapeutic approaches currently in use for MS treatment toward control of astrocyte purine-based interaction with immune cells.

AB  - Epilepsy is a neurological disorder caused by the pathological hyper-synchronization of neuronal discharges. The fundamental research of epilepsy mechanisms and the targets of drug design options for its treatment have focused on neurons. However, approximately 30% of patients suffering from epilepsy show resistance to standard anti-epileptic chemotherapeutic agents while the symptoms of the remaining 70% of patients can be alleviated but not completely removed by the current medications. Thus, new strategies for the treatment of epilepsy are in urgent demand. Over the past decades, with the increase in knowledge on the role of glia in the genesis and development of epilepsy, glial cells are receiving renewed attention. In a normal brain, glial cells maintain neuronal health and in partnership with neurons regulate virtually every aspect of brain function. In epilepsy, however, the supportive roles of glial cells are compromised, and their interaction with neurons is altered, which disrupts brain function. In this review, we will focus on the role of glia-related processes in epileptogenesis and their contribution to abnormal neuronal activity, with the major focus on the dysfunction of astroglial potassium channels, water channels, gap junctions, glutamate transporters, purinergic signaling, synaptogenesis, on the roles of microglial inflammatory cytokines, microglia-astrocyte interactions in epilepsy, and on the oligodendroglial potassium channels and myelin abnormalities in the epileptic brain. These recent findings suggest that glia should be considered as the promising next-generation targets for designing anti-epileptic drugs that may improve epilepsy and drug-resistant epilepsy.

AB  - The neurotransmitter norepinephrine (NE) plays a central role in regulating arousal,
attention, cognitive function and stress responses. Unlike fast neurotransmitters which
act at synapses, NE is released in the neuropil and performs multiple targeting in the
surrounding area. The glial cells astrocytes are a direct target of NE, as they express
all adrenergic receptor subtypes and respond with Ca2+ increases to NE. Astroglial
responses elicited by strong and transient increases of NE in the brain are well studied,
but the effect of a low background NE concentration on astrocytes is unknown. This
background level of NE is maintained by basal noradrenergic activity and is
constantly present in the brain. Therefore, the response of astrocytes to the
background NE could have been unintentionally evoked in previous studies but its
effect overlooked.

To assess action of background NE on astrocytes we combined the whole-cell patch-
clamp, immunohistochemistry, Ca2+ imaging and pharmacology. We used cultured

cortical astrocytes to bypass NE targeting of multiple cell types.
We show that cortical astrocytes detect and respond to the background NE
concentration with an increase in intracellular Ca2+. This Ca2+ liberated from
intracellular stores further increased large-conductance, Ca2+-sensitive potassium
(BK) currents in astrocytes. Notably, immunohistochemistry data showed that BK
channels and alpha 1 adrenoreceptor are highly expressed in astrocytes in the rat
cortex. Furthermore, stimulation of astrocytes by background NE was inhibited by
alpha-adrenoceptor antagonist.
Our results suggest that astrocytes maintain basal brain activity by perceiving and
responding to the background NE.

AB  - The astrocytic network maintains homeostasis in the central nervous system (CNS)
through interactions with neighboring cells. In the CNS autoimmune disease, multiple
sclerosis (MS), neuroinflammatory conditions modulate these cell-to-cell interactions.
Our previous work revealed that the immune cells infiltrated into the CNS (CNS-IICs)
of experimental autoimmune encemphalomyelitis (EAE) rat, an animal model of MS,
rapidly alter the activity pattern of astrocytes by activating the glial P2X7 receptor
(P2X7R). In the present study we further defined the mechanisms responsible for
astrocytes’ activation in the presence of CNS-IICs. For this purpose, we used an in
vitro experimental setup and monitored Ca2+ dynamics in Fluo-4-labeled cultured
naïve astrocytes following brief bath application of CNS-IICs isolated from the spinal
cord of the EAE rat. Our data indicate that the astroglial αvβ3-integrin is involved in
the initial contact of astrocytes with CNS-IICs, since blocking αvβ3-integrin reduced
the expected astrocytic Ca2+ response. Furthermore, blocking of mitochondrial
Na+
/Ca2+- and H+

/Ca2+- exchangers in astrocytes promoted an augmentation of the
intracellular Ca2+ increase and a higher ATP release after brief exposure to CNS-IICs,
demonstrating that mitochondria regulate the astrocyte-CNS IICs cell-cell interaction.
Overall, our study expands the understanding of astrocytes’ interaction with
autoreactive immune cells that are present in their local environment in an
autoimmune disease. This offers a new conceptual framework for considering direct
astrocyte–immune cell interaction to design new strategies for therapy development in
the treatment of MS.

AB  - Gonadotropin-releasing hormone (GnRH) is a hypothalamic decapeptide that controls
mammalian reproduction by acting on its receptor (GnRHR) expressed on pituitary
gonadotrope cells. While GnRHR signaling in gonadotropes is well described,
knowledge of GnRHR activation-related events at extrapituitary sites including
neurons is limited. It was proposed that GnRH analogs (GnRHa) induce distinct
changes in hippocampal gene expression, emotional processes, and cognitive
functions.
To explore neuronal GnRHR signaling we used the human neuroblastoma cell line
SH-SY5Y. Further, we explored the regional expression of Gnrhr in rat brain and
investigated the expression of several relevant genes in the hippocampus and preoptic
area of peripubertal male rats treated with GnRHa.
GNRHR is expressed in SH-SY5Y cell line, but its expression does not change after
adding GnRHa in the incubation media. Electrophysiological recordings confirmed
that GnRHa induced membrane depolarization but could not evoke action potentials.
In the rat brain, Gnrhr expression could be detected in the hippocampus, amygdala,
and hypothalamus, including the preoptic area. Prolonged treatment of peripubertal
rats with GnRHa had no effect on the expression of genes in the hippocampus
previously shown to be affected in the sheep model of delayed puberty.
These results imply that neuronal GnRHR is either differently coupled (not coupled
with Gq/11 protein), or that its membrane density is too low to induce transcriptional
events. More investigation is needed to elucidate the role(s) of GnRH-GnRHR
signaling in the brain.

AB  - BACKGROUND
According to World Health Organization, 70-95% of the population chooses folk medicine as their primary
approach for health maintenance. In addition to their healing properties and application in folk medicine,
Lamiaceae plants are often valued in cookery as spices and food preservatives.
OBJECTIVES
Hence, the aim of this study was to examine the antibiofilm activity of 12 ethanolic extracts of Lamiaceae species
on biofilm formation and the degradation of existing biofilm of Pseudomonas aeruginosa PAO1 (ATCC 15692).
METHODS
The crystal violet staining method was used to evaluate the newly formed bacterial biofilms. Four concentrations
(double dilutions) of plant extracts (starting conc. 2500 μg/mL), solvent control (ethanol, starting conc.15%),
and positive control (streptomycin, starting conc. 12.5 μg/mL) were tested.082
RESULTS
All ethanol extracts showed antibiofilm activity. However, the strongest activity was observed for Hyssopus
officinalis, Melissa officinalis, Mentha piperita, and Ocimum basilicum, where the viability of bacteria in the
biofilm after treatment was about 60% mainly at each tested concentration. Teucrium chamaedrys extract
exhibited the strongest activity by degrading about 60% of biofilm (about 40% viability) at all concentrations

According to World Health Organization, 70-95% of the population chooses folk medicine as their primary
approach for health maintenance. In addition to their healing properties and application in folk medicine,
Lamiaceae plants are often valued in cookery as spices and food preservatives.
OBJECTIVES
Hence, the aim of this study was to examine the antibiofilm activity of 12 ethanolic extracts of Lamiaceae species
on biofilm formation and the degradation of existing biofilm of Pseudomonas aeruginosa PAO1 (ATCC 15692).
METHODS
The crystal violet staining method was used to evaluate the newly formed bacterial biofilms. Four concentrations
(double dilutions) of plant extracts (starting conc. 2500 μg/mL), solvent control (ethanol, starting conc.15%),
and positive control (streptomycin, starting conc. 12.5 μg/mL) were tested.082
RESULTS
All ethanol extracts showed antibiofilm activity. However, the strongest activity was observed for Hyssopus
officinalis, Melissa officinalis, Mentha piperita, and Ocimum basilicum, where the viability of bacteria in the
biofilm after treatment was about 60% mainly at each tested concentration. Teucrium chamaedrys extract
exhibited the strongest activity by degrading about 60% of biofilm (about 40% viability) at all concentrations
except at the lowest tested one. Promising results were also observed for M. piperita (at each of the tested
concentrations) and O. basilicum (at the highest tested concentration), where the viability of bacteria in the
biofilm after treatment was reduced by about 40%. The remaining extracts showed a slightly lower effect on
the degradation of the previously formed biofilm of P. aeruginosa PAO1.",

AB  - BACKGROUND
The increasing bacterial resistance to antibiotics poses a serious global threat. For that reason, the research into plant-derived antibacterial agents has become progressively more interesting, particularly in regard to their capacity to prevent the delay or inability of wound closure and healing.
OBJECTIVES
The aim of this study was to evaluate i) the antibacterial potential of ethanolic extracts (70% ethanol) of 18
Lamiaceae species against four Gram-negative and three Gram-positive bacterial strains; ii) the effect of these extracts on Pseudomonas aeruginosa PAO1 infection of human lung fibroblasts (MRC-5), and iii) the effect on MRC-5 cell migration.
METHODS
The antibacterial activity was tested by minimal inhibitory concentration (MIC) assay. The effect on bacterial infection of MRC-5 cells was determined using the invasion assay, while the cell migration was assessed with Scratch assay.
RESULTS
The tested Gram-positive bacteria, especially Bacillus subtilis, are more sensitive to the effects of ethanolic extracts than the Gram-negative bacteria. Moreover, the tested extracts significantly inhibited the invasion of Pseudomonas aeruginosa PAO1 during MRC-5 infection, and most of them also displayed promising stimulating potential on MRC-5 migration in a disrupted cell monolayer. Finally, the results of IBR (integrated biomarker response) analysis highlighted Salvia officinalis ethanolic extract as the most active one, which is in accordance with the existing data suggesting that this plant represents an effective antibacterial and wound-healing agent commonly used in traditional medicine. Altogether, these results are expected to foster further studies that will focus on combating bacterial resistance to antibiotics using natural products.

We present changes of enzymatic component of antioxidative system in succulent plant Tacitus
bellus that specifically correspond to subsequent phases (spore germination, biotrophic phase,
and necrotrophic phase) of hemibiotroph Fusarium verticillioides infection. T. bellus response to F.
verticillioides spore germination was characterized by transient increase in catalase (CAT), but decrease in superoxide dismutase (SOD) and peroxidase (POD) activity. During biotrophic phase of F.
verticillioides infection, when hyphae spread intercellularly in epidermal and mesophyll tissue, host
antioxidative system was suppressed. The transition from biotrophic to necrotrophic phase (inter
and intracellular colonization and sporulation) triggered the host plant cells to create a highly defensive environment: CAT, SOD and POD activities were significantly stimulated, slowing, or even
currently arresting, colonization of T. bellus mesophyll cells. CAT, showing the most pronounced
activity increase, could be suggested as the main enzyme responsible for slowing the progression
of necrotrophic phase of F. verticillioides growth. However, contrary to host CAT and SOD which
isoenzyme profile didn’t change, new highly acidic POD isoforms replaced the two mildly acidic
isoforms, suggesting their specific role in slowing the progression of infection. Presented results

AB  - Biological activity of 2-tert-butyl-1,4-benzoquinone (TBQ) and its derivatives, 2-tert-butyl-5-(2-propylthio)-1,4-benzoquinone, 2-tert-butyl-5- -(propylthio)-1,4-benzoquinone, 2-tert-butyl-5,6-(ethylenedithio)-1,4-benzoquinone, 2-tert-butyl-5-(phenylthio)-1,4-benzoquinone and 2-tert-butyl-6-(phenylthio)- 1,4-benzoquinone, were tested for their antioxidant, antibacterial, toxic, cytotoxic and genotoxic potential. Using the DPPH test, all derivatives showed good antioxidant activity, better than ascorbic acid, and the 2-tert- -butyl-5-(propylthio)-1,4-benzoquinone derivative showed the strongest effect. Better antibacterial potential was observed against Gram-positive bacteria in the broth microdilution method in which the 2-tert-butyl-5-(phenylthio)-1,4- -benzoquinone derivative showed the strongest activity (MIC = 15.6 μM). The results of toxicity tests, using the Brine shrimp test, indicated that the derivatives lose their toxic potential compared to TBQ, except for 2-tert-butyl-6- -(phenylthio)-1,4-benzoquinone, which showed a 3 times stronger effect. Cytotoxicity was assessed by the MTT assay in 24 and 72 h treatments in MRC-5, HS 294T and A549 cell lines in threefold decreasing gradient (11, 33 and 100 μM). Modifications potentiate the cytotoxic effect, and the strongest effect was observed with the 2-tert-butyl-5,6-(ethylendithio)-1,4-benzoquinone derivative. In addition, the genotoxic potential was examined in the MRC-5 cell line using the comet assay. All tested derivatives of TBQ showed a genotoxic effect at all applied subtoxic concentrations. In general, the chemical modifications of TBQ enhanced its biological activity.

AB  - The effects of a fructose-rich diet and chronic stress on copper metabolism in the kidneys
are still understudied. We investigated whether fructose and/or chronic unpredictable stress modulate
copper metabolism in a way that affects redox homeostasis, thus contributing to progression
of metabolic disturbances in the kidney. We determined protein level of copper transporters,
chaperones, and cuproenzymes including cytochrome c oxidase, as well as antioxidant enzymes
function in the kidneys of male Wistar rats subjected to 20% liquid fructose supplementation
and/or chronic stress. Liquid fructose supplementation increased level of copper chaperone of
superoxide dismutase and decreased metallothionein level, while rendering the level of copper
importer and copper chaperones involved in copper delivery to mitochondria and trans Golgi
network unaffected. Stress had no effect on renal copper metabolism. The activity and expression
of renal antioxidant enzymes remained unaltered in all experimental groups. In conclusion, fructose,
independently of stress, decreased renal copper level, and modulated renal copper metabolism
as to preserve vital cellular function including mitochondrial energy production and antioxidative
defense, at the expense of intracellular copper storage.

AB  - Epilepsy and multiple sclerosis (MS), two of the most common neurological diseases, are characterized by the establishment of inflammatory environment in the central nervous system that drives disease progression and impacts on neurodegeneration. Current therapeutic approaches in the treatments of epilepsy and MS are targeting neuronal activity and immune cell response, respectively. However, the lack of fully efficient responses to the available treatments obviously shows the need to search for novel therapeutic candidates that will not exclusively target neurons or immune cells. Accumulating knowledge on epilepsy and MS in humans and analysis of relevant animal models, reveals that astrocytes are promising therapeutic candidates to target as they participate in the modulation of the neuroinflammatory response in both diseases from the initial stages and may play an important role in their development. Indeed, astrocytes respond to reactive immune cells and contribute to the neuronal hyperactivity in the inflamed brain. Mechanistically, these astrocytic cell to cell interactions are fundamentally mediated by the purinergic signalling and involve metabotropic P2Y1 receptors in case of astrocyte interactions with neurons, while ionotropic P2X7 receptors are mainly involved in astrocyte interactions with autoreactive immune cells. Herein, we review the potential of targeting astrocytic purinergic signalling mediated by P2Y1 and P2X7 receptors to develop novel approaches for treatments of epilepsy and MS at very early stages.

The highest concentrations of Cu in liver as well as Ba, Ca, Fe, Mn, Na, P, and Sr in gills were detected in all fish species, while the lowest concentrations of Cu, Fe, Mn, Na, and Zn were detected in muscle. Pikeperch had significantly lower concentrations of Ba in all tissues compared to the other species, as well as Fe, P, and Sr in muscle, K, Mg, Mn, Sr, and Zn in gills, and Fe in gonads. European chub had significantly higher concentrations of Ca, Cu, and Zn in muscle, Cu in liver, and Cr and Cu in gonads compared to Cactus roach and pikeperch. Cd concentration in one individual of Cactus roach exceeded the maximum allowed concentration. The muscle was exposed to the lowest pressure of metal pollution in all species, and European chub accumulated more metals compared to the other species. There is no significant health risk due to consumption of investigated species. A major hazard index (HI) contributor in all species was Hg. According to the target carcinogenic risk factor (TR), target hazard quotient (THQ), and HI, men are under lower health risk compared to the women. The TR and THQ for As, Cr, Cu, Fe, Mn, Ni, and Zn as well as HI values were higher for European chub compared to the other species. On the other hand, THQ for Hg was highest for pikeperch.

AB  - We describe an approach for studying the physiology of single live cells using the conceptionally novel upright microscope/patch-clamp configuration. Electrophysiology experiments typically require a microscope with the fixed stage position and the motion control of the microscope objective. Here, we demonstrate that a microscope with a z-axis movable stage and a fixed objective can also be efficiently used in combination with the patch-clamp technique. We define a set of underlying principles governing the operation of this microscope/patch-clamp configuration and demonstrate its performance in practice using cultured astrocytes, microglia, and oligodendrocytes. Experimental results show that our custom configuration provides stable recordings, has a high success rate of the whole-cell patch-clamp trials, can be effectively applied to study cellular physiology of glial cells, and provides comparable performance and usability to the commercially available systems. Our system can be easily replicated or adapted to suit the needs of the research groups and can be cost-effective in reducing the investments in purchasing additional equipment. We provide step-by-step instructions on implementing an upright microscope with z-axis movable stage as a routine workhorse for patch-clamping.

AB  - In this study, mycelium of fungus Phycomyces blakesleeanus was exposed to soluble toxic form of selenium, selenite (Se+4), with the aim of determining the flow and products of its biotransformation. Selenite is reduced to Se0 in the form selenium nanoparticles (SeNPs) and Se-2 in the form of methylated volatile selenides. Low concentrations of Se+4 in the mycelium form RSSeSR type compounds, which could be a step in the process of SeNPs formation, or incorporation of Se into metabolites such as Se-amino acids.
