AB  - 1.	Black bullhead is among the most abundant and successful non-native fish species in European freshwaters. A number of studies have indicated that its physical removal could be a potential solution to minimize possible negative impacts that it may have on native fishes; however, so far there have been no field studies to confirm this.
2.	This study quantified population dynamics of both native and non-native fishes in a small slow-running lowland river within the Ponjavica Nature Park in Serbia before and after the black bullhead removal with fyke-nets, which proved to be an efficient tool for this purpose.
3.	The removal of black bullhead resulted in statistically significant changes in two native species abundance – an increase of rudd (Scardinius erythrophthalmus) (by 5.3 times), and a decline of bleak (Alburnus alburnus) (by 2.3 times).
4.	Significant increase was observed in three non-native fish species: the abundances of topmouth gudgeon (Pseudorasbora parva), pumpkinseed (Lepomis gibbosus), and Prussian carp (Carassius gibelio) increased 25.5, 4.9, and 4.2 times, respectively.
5.	There were also substantial changes in the diversity of the fish assemblage after the black bullhead removal, illustrated by changes in diversity indices: Shannon's index doubled, while the Simpson’s dominance index decreased threefold.
6.	The catch-per-unit-effort and the biomass-per-unit-effort values indicated the dominance of the black bullhead in the fish assemblage. YOY/adult ratio did not vary in relation to abundance, which confirmed that black bullhead might not compensate for fishing mortality with the increased recruitment.
7.	The results suggest that black bullhead plays a significant role in structuring the fish assemblage and that its removal may have both positive and negative effects on species abundance and diversity. These findings can contribute to the conservation of native fish species and improvement of future management programs.

AB  - Guttation, the formation of exudation water, is widespread among plants and fungi, yet the 
underlying mechanisms remain largely unknown. We describe the conditions for inducing guttation in sporangiophores of the mucoracean fungus, Phycomyces blakesleeanus. Cultivation on 
peptone-enriched potato dextrose agar elicits vigorous guttation mainly below the apical growing 
zone, while sporangiophores raised on a glucose-mineral medium manifest only moderate guttation. 
Mycelia do not guttate irrespective of the employed media. The topology of guttation droplets 
allows identifying the non-growing part of the sporangiophore as a guttation zone, which responds 
to humidity and medium composition in ways that become relevant for turgor homeostasis and thus the sensor physiology of the growing zone. Apparently, the entire sporangiophore, rather than 
exclusively the growing zone, participates in signal reception and integration to generate a common growth output. Exogenous auxin applied to the growing zones elicits two correlated responses: (i) formation of guttation droplets in the growing and transition zones below the sporangium and (ii) a diminution of the growth rate. In sporangiophore populations, guttation-induction by exogenous control buffer occurs at low frequencies; the bias for guttation increases with increasing auxin concentration. Synthetic auxins and the transport inhibitor NPA suppress guttation completely, but leave growth rates largely unaffected. Mutants C2 carA and C148 carA madC display higher sensitivities for auxin-induced guttation compared to wild type. A working model for guttation includes aquaporins and mechanosensitive ion channels that we identified in Phycomyces by sequence domain searches.

AB  - Cerium oxide nanoparticles (nCeO2) are interesting nanomaterials due to their redox properties. Their wide application could result in unexpected consequences to environmental safety. Unlike acute toxicity, the trans-generational effects of carbohydrate-coated nCeO2 in the environment are still unknown. The main aim of this study was to investigate the effect of treating maternal plants of Chenopodium rubrum L. (red goosefoot) and Sinapis alba L. (white mustard) with uncoated (CeO2) and glucose-, levan-, or pullulan-coated nCeO2 (G-, L-, or P-CeO2) during seed germination on morphological and physiological characteristics of produced seeds in two subsequent generations. The plant response was studied by measuring germination percentage (Ger), total protein content (TPC), total phenolic content (TPhC), total antioxidative activity (TAA), and catalase (CAT) activity. Results showed that maternal effects of the different nCeO2 treatments persist to at least the second generation in seeds. Generally, C. rubrum was more sensitive to nCeO2 treatments than S. alba. The coated nCeO2 were more effective than uncoated ones in both plant species; L- and P-CeO2 were the most effective in S. alba, while CeO2 and G-CeO2 had a dominant impact in C. rubrum. Enhanced germination in all tested generations of S. alba seeds recommends nCeO2 for seed priming.

AB  - The paper discusses a problem in higher education related to students' progress and performance in exams. During the semester, every student would benefit from information about whether their work on the course is sufficient to achieve the desired result on the final exam. If it was pointed out to them at the right moment that success in the subject is likely to be absent, it could encourage them to increase efforts for the rest of the semester and thus in the end achieve their goal. However, if a bad result is expected for most participants, a change in the teaching method should be considered. Therefore, in this research, two aims have been set:  to determine the moment during the semester when it can be said that a certain student will not successfully complete the course and to check that the teaching methods are appropriate. In order to give advice to the student in a timely manner, at certain moments during the semester, it is necessary first to diagnose the level of their knowledge, and then make a prediction of the expected result on the exam. In the solution proposed in this paper, in five time moments (t2,...,t6) the student's knowledge is assessed using the Multiple-Criteria Decision Making (MCDM) method - PROMETHEE II, which considers four criteria (attendance, activity, homework, and test), and the teacher's preferences. Thus, a progress function for a given student is obtained, which shows how they are progressing toward the set goal. Based on the values of the progress function in milestones t2-t6, student achievement is categorized through grades. In this investigation, we have used the k-Nearest Neighbors (kNN) Algorithm for grade classification. Our findings clearly justify that MCDM and kNN models are appropriate for tracking, classifying, and forecasting student grades.

AB  - North American black bullhead (Ameiurus melas) is an ictalurid species that has become
widespread outside of its native range, causing undesirable ecological impacts. Numerous
studies have suggested that its physical removal could be a way to reduce any potential
detrimental effects of this species. This study measured the effects on population dynamics of
both native and non-native fish species following the removal of 20,145 black bullheads from
the Ponjavica Nature Park. The most significant changes between the zero-point state and the
post-removal state have been recorded among the populations of non-native fish species: the
abundances of topmouth gudgeon (Pseudorasbora parva), pumpkinseed (Lepomis gibbosus),
and Prussian carp (Carassius gibelio) increased 25.5, 4.9, and 4.2 times, respectively.
Previous research has shown that smaller black bullhead individuals enter into competitive
relationships with the topmouth gudgeon, while larger individuals use the topmouth gudgeon
as prey. By removing black bullhead individuals from the ecosystem, a part of the ecological
niche used by both species was freed. Also, the predatory pressure on topmouth gudgeon
decreased by removing larger black bullhead individuals. All these factors led to an increase
in the abundance of topmouth gudgeon. Black bullhead and pumpkinseed have overlapping
diets and are therefore considered competitors for food. Moreover, research on the black
bullhead's feeding ecology showed that this species feeds on the pumpkinseed. When a
greater number of black bullhead individuals were removed from the ecosystem, it led to an
increase in the abundance of pumpkinseed. The abundance of Prussian carp also increased
after the removal of the black bullhead. The Prussian carp and the black bullhead are quite
similar in terms of diet habits, habitat preferences, and reproductive characteristics. Since
these two species are in direct competition, the decline in the black bullhead population
contributed to an increase in the Prussian carp population. These results point to the fact that
management programs must include multiple species and methods, and one of them is the
removal of all undesirable, invasive non-native species. Further research should also focus on
possible diet shifts in allochthonous fishes after removing the black bullhead.

AB  - Црни амерички патуљасти сом (Ameiurus melas) представља једну од најзаступљенијих и најуспешнијих инвазивних врста риба која насељава копнене воде Европе, укључујући и Србију. У досадашњим истраживањима напомиње се да би санациони излов могао да буде потенцијално решење проблема које ова врста изазива у водама у којима је интродукован. У овом истраживању, реализованом од јуна 2018. до октобра 2019. године, квантификована је популациона динамика аутохтоних и алохтоних врста риба у Парку природе „Поњавица“ након селективног излова црног америчког патуљастог сома. Укупно је изловљено 20.145 јединки ове врсте што је утицало на абунданцу и аутохтоних и алохтоних врста риба. Статистички значајно повећање абунданце забележено је код црвенперке (Scardinius erythrophthalmus) (5,3 пута), док се абунданца уклије (Alburnus alburnus) смањила 2,3 пута. Најзначајнија промена забележена је међу популацијама алохтоних врста риба. Абунданца амурског чебачока (Pseudorasbora parva) повећана је 25,5 пута, сунчице (Lepomis gibbosus) 4,9 пута и бабушке (Carassius gibelio) 4,2 пута. Вредност Shannon-овог индекса диверзитета (H)1 била је двоструко већа након ове интервенције, док се вредност Simpson-овог индекса доминантности (C)2 смањила три пута. Вредности улова по јединици напора (енгл. catch-per-unit-effort – CPUE) и биомасе по јединици напора (енгл. biomass-per-unit-effort – BPUE) свих узоркованих врста током селективног излова показују доминацију црног америчког патуљастог сома. Резултати указују на то да је селективни излов ове врсте имао како позитивне, тако и негативне последице на насеље риба на истраживаном подручју.

AB  - In this study, the movements and behaviour of Wels catfish (Silurus glanis, Linnaeus, 1758) were
monitored during the different seasons when the water level in the river changed significantly. Wels
catfish was caught on the Danube River, rkm 863, and tagged with an ultrasonic transmitter.
Deployed Vemco receivers recorded detections of spatial movement between years 2015 and 2017.
Our telemetry data found relatively short movements within a maximum range (~12km), but as a
territorial species most of the time it was recorded by the two receivers, close to the Iron Gate dam
and location where it was caught. Circadian rhythm showed that in the summer period, nocturnal
activity is evident while during winter Wels catfish stayed most of the time at the same depth under
the water surface. Wels catfish changed depths during the autumn and spring when more activity
was recorded. The last signal received was during the winter 2017, which was period with the low
temperatures and ice cover on the Danube River. This research shows the value and importance of
installing coded acoustic transmitters in fish and monitoring their movement using a series of
autonomous receivers deployed in the Danube River. Research by telemetry can be used to better
understand fish behaviour and movements and to help improve large river management measures.

AB  - The various applications of cerium oxide nanoparticles (nCeO2), one of the most produced metal oxide nanoparticles, could affect environmental health due to accumulation of uncoated and coated nCeO2 with increased suspension stability. The trans-generational effects on seed characteristics are important components of the life histories of plants representing the pathway from adult to offspring that completes the life cycle. The effects of carbohydrate-coated nCeO2 on the plant seeds through the generations are still unknown. The main aim of this study was to investigate the effect of the treatment of maternal Sinapis alba and Chenopodium rubrum plants with 200 mg/L of uncoated (CeO2) and glucose-, levan-, or pullulan coated nCeO2 (G-, L-, оr P-CeO2) on germination of three generations of seeds. Sinapis alba was selected as a hyperaccumulator of heavy metals, while Chenopodium rubrum was selected as a short-day plant and weed. In Sinapis alba, the results of germination on the 4th day revealed increased germination after the treatment with CeO2 and L-CeO2 nanoparticles in zero generation and after all nCeO2 treatments in the 1st and 2nd generation of seeds. In Chenopodium rubrum, there were no changes after the treatments. It can be concluded that trans-generational effects of the different nCeO2 treatments persist to at least the second generation in seeds. Compared to the same generation control, the 2nd generation of seeds showed the highest sensitivity. The coated nCeO2 were more effective than the uncoated ones. Enhanced germination in three generations of S. alba seeds recommends nCeO2 for application in seed-priming.

AB  - Plant nanobionics studies nanoparticles application toplants, which improves certain plant functions. Due to many limitations, plants use less photosynthetic capacity thanit is theoretically possible, so an increase in leaf photosynthesis canbe important for increasing crop yield. For this purpose, carbon dots (CDs) as organic, non-toxic nanoparticles with a huge potential for application can be used. They are a green alternative to metal nanoparticles. The main advantages of these nanoparticles are their easy preparation, high water solubility, biocompatibility, and photoluminescence. The main aim of this research was to investigate the effect of orange carbon dots (o-CDs), synthesized from citric acid and o-phenylenediamine as precursors, on photosynthetic efficiency increase in maize (Zea mays L.), as a model plant and agricultural species. We applied o-CDs in three different concentrations (1, 5, and 10 mg/L) by adding to the hydroponic growth solution or foliarly. The photosynthesis parameters (photosynthetic rate, transpiration rate, water use efficiency) and content of photosynthetic pigments (chlorophyll a and b, carotenoids) were recorded. The results showed that the photosynthetic parameters’ values were higher for foliar than for solution application. Amount of 1 mg/L o-CDs applied foliarly and 5 mg/L in solution increased photosynthetic parameters in leaves. The photosynthetic pigments were enhanced after o-CDs treatments. Finding that o-CDs have photosynthesis enhancing potential without harming plants opens new opportunities in their use in agricultural applications, such as increasing plant productivity.

AB  - Cerium oxide nanoparticles (nCeO2) are attracting continuously growing attention due to their unique properties  - their facile transition between Ce3+ and Ce4+ oxidation states. nCeO2 found application in the industry, cosmetics, agriculture, electronics, etc.  Their final accumulation in the environment creates new environmental stress factors for living organisms. To improve their solubility, nCeO2 were coated with monosaccharide - glucose and microbial exopolysaccharides - levan and pullulan to obtain glucose-, levan-, and pullulan-coated nCeO2 (G-CeO2, L-CeO2, and P-CeO2). The potential long-term effect of nCeO2 on vegetation was studied in two herbaceous weedy annuals - Sinapis alba and Chenopodium rubrum. It was suggested earlier that the mechanism of maternal environmental effects, that persists for several generations, can act through relative seed protein composition representing an “archive“ of environmental changes experienced by mother plants during their lives. Treatment with nCeO2 of Sinapis alba and Chenopodium rubrum seeds during germination, on total protein content (TPC) and protein profile of seeds produced in two subsequent offspring generations grown in the greenhouse, were investigated. The TPC mainly showed no significant differences, both between treatments and between subsequent generations, in both species. SDS-PAGE electrophoresis showed the presence of 15 protein bands, molecular weight 10 - 140 kDa, in all seed samples of Sinapis alba or Chenopodium rubrum, respectively. We showed that nCeO2 treatment during the very early development of mother plants (germination) has a long-term effect, visible in the difference in width and intensity of seed protein bands of seeds sampled in two subsequent offspring generations.

AB  - Cerium oxide nanoparticles (nCeO2) are nanomaterial widely used in electronics, cosmetics, catalysis, and fuel additives production due to their transition between Ce3+ and Ce4+ oxidation states. Their increasing production (around 10,000 metric tons per year) makes them one of the most produced metal oxide nanoparticles which can lead to unexpected consequences to environmental health and safety. Coating nCeO2 with different polymers is a very popular way to increase their suspension stability, but the data on their effect on cultivated plants are scarce. Environmental effects on morphological and physiological properties of offspring which occur during the development of the mother plant are called maternal environmental effects. Their expression depends on the offspring’s environment, they are expressed throughout the life cycle of the offspring and may persist for several generations. It was suggested that components of the nonenzymatic antioxidant system might participate in the mechanism governing the maternal environmental effects. Total antioxidant activity (TAA) comprises the contribution of different non-enzymatic components with antioxidant capacity. Herbaceous weedy annuals Sinapis alba and Chenopodium rubrum were selected, as a heavy metal hyperaccumulator plant i.e. a species with strong maternal effects, respectively. The effect of uncoated (CeO2) and glucose-, levan-, and pullulan- coated nanoparticles (G-CeO2, L-CeO2, P-CeO2) treatment of Chenopodium rubrum and Sinapis alba seeds during germination, on TAA of seeds produced in two subsequent generations of plants grown in a greenhouse, were investigated. TAA was measured using the ABTS/HRP end point method. Results showed that the effect of nCeO2 treatments was more expressed in Sinapis alba seeds; mainly all nanoparticles treatments during germination of mother plants resulted in the increase in TAA of produced seeds in both monitored generations. In contrast, in Chenopodium rubrum CeO2 treatment resulted mainly in the decrease in TAA of produced seeds in both monitored generations. The presented effect was equally expressed in both generations. Among nanoparticles, L-CeO2 showed the most pronounced effect in both generations of the plants. We showed that the effect of nCeO2, applied during the early development of mother plants (germination), is visible in changes in the components of the nonenzymatic antioxidant system of produced seeds and that it persists for (at least) two generations. In other words, seed priming with nCeO2 might affect changes in yield antioxidant capacity through several generations.

AB  - The growing zone (GZ) of the unicellular coenocytic sporangiophore of Phycomyces blakesleeanus represents the site of stimulus reception (light, gravity, gas) and stimulus response, i.e., local modulations of the elongation growth, which may result, in dependence of the stimulus direction, in tropic bending. Until now, evidence for a possible participation of the columella in sensory reception is absent. We confirm with light microscopy earlier studies that show that the GZ and the columella are not separated by a membrane or cell wall, but rather form a spatial continuum that allows free exchange of cytoplasm and organelle transport. Evidence is presented that the columella is responsive to external stimuli. Columellae, from which spores and sporangial cell wall had been removed, respond to exogenous auxin with a local depolarization of the membrane potential and an increased growth rate of the GZ. In contrast, auxin applied to the GZ causes a decrease of the growth rate irrespective of the presence or absence of sporangia. The response pattern is specific and relevant for the sensory reception of Phycomyces, because the light-insensitive mutant C148carAmadC, which lacks the RAS-GAP protein MADC, displays abnormal IAA sensitivity and membrane depolarization. We argue that the traditional concept of the GZ as the only stimulus-sensitive zone should be abandoned in favor of a model in which GZ and columella operate as a single entity capable to orchestrate a multitude of stimulus inputs, including auxin, to modulate the membrane potential and elongation growth of the GZ.

AB  - INTRODUCTION:
Carbon dots (CDs) are considered a green alternative to metal nanoparticles because they can be used where metal nanoparticles cannot be applied. Orange carbon dots (CDs), synthesized from citric acid and o-phenylenediamine as precursors, are organic spherical nanoparticles with a lot of applications in various biomedical purposes such as drug delivery, bioimaging, and sensing. Ease of preparation, high photoluminescence, solubility in water, and biocompatibility are their main advantages.
OBJECTIVES:
The main aim of this research was to investigate the effect of oCDs on total phenolic activity (TPC) in maize as an agricultural species. TPC reflects the contribution of phenolics as a group of secondary metabolites participating in the regulation of plant growth and in the defense responses. Also, it is one of the main indicators of oxidative stress which can cause a metabolic disorder in plants.
METHOD / DESIGN:
Three different concentrations (1, 5, and 10 mg L-1) of oCDs nanoparticles were used for the treatment of maize plants via KNOP/2 hydroponic solution during 2 week-growth under 16 h/8 h photoperiod. TPC was analyzed from phenolic extracts obtained from the roots and leaves of plants after foliar and solution treatments. Folin-Ciocalteu’s spectrophotometric procedure was used for the determination of TPC in the samples.
RESULTS:
The results showed that foliar applications with all concentrations of o-CDs induced decreases of TPC in maize leaves but did not affect these parameters in the roots. In solution treatment, the concentration of 1 mg/L of o-CDs increased TPC in the leaves, but decreased in roots.
treatment
CONCLUSIONS:
The higher efficiency achieved with the lowest o-CD concentration (1 mg/L) in foliar treatment makes this way of application advantageous compared with the solution counterpart.

AB  - Carbon dots (CDs) are spherical organic nanoparticles with a huge potential for application in various biomedical purposes such as sensing, bioimaging, and drug delivery, as well as in water remediation. The discovery of CDs was very popular in the 21th century because they can be used where metal nanoparticles cannot be applied, so they are considered as their green alternative. The main advantages of these nanoparticles are their ease of preparation, solubility in water, high photoluminescence, and biocompatibility. Having all these properties in mind, the main aim of this research was to investigate the effect of orange carbon dots (oCDs), synthesized from citric acid and o-phenylenediamine as precursors, on total antioxidative activity (TAA) in maize as a model plant and agricultural species. We tested antioxidative activity as an indicator of oxidative stress and metabolic disorder in plants. TAA mainly includes the contribution of different non-enzymatic components with antioxidant capacity (vitamins, phenolic acids, sugars, etc.). The maize plants were exposed to three different concentrations (1, 5, and 10 mg L-1) of oCDs nanoparticles via KNOP/2 hydroponic solution during growth under 16 h/8 h photoperiod. After the 2 week-growth,  the leaves and roots of plants were separately harvested and collected. The results showed that oCDs did not induce any change in TAA in the leaves, but increased TAA in roots after the treatment of plants with 5 and 10 mg L-1 oCDs. It can be concluded that plant treatment with oCDs’ concentrations ≥ 5 mg L-1 leads to the increase of oxidative stress in roots as a plant organ more exposed to the nanoparticles. This research opens new possibilities in the uses of oCDs in agricultural applications.

AB  - The sustained increase in leaf photosynthesis may increase crop yield. Due to many limitations, plants use much less photosynthetic capacity than is theoretically possible. Plant nanobionics investigates nanoparticle application in living plants, which improves certain plant functions. We synthesized and tested nontoxic orange carbon dots (o-CDs) for the photosynthetic efficiency increase in maize (Zea mays L.). We applied o-CDs foliarly or by adding to the growth solution. The photosynthetic parameters and content of photosynthetic pigments were recorded. The total phenolic content (TPC) and total antioxidant activity (TAA) were measured to monitor the plant antioxidant response to o-CDs. The photosynthetic parameters' values were higher for foliar than for solution application. The 1 mg/L o-CDs applied foliarly and 5 mg/L in solution increased photosynthetic parameters in leaves. The o-CDs raised photosynthetic pigments. The TAA and TPC results indicate reduced antioxidant activity in the plant organs more exposed to o-CDs, depending on the way of application.

abstract = "The sustained increase in leaf photosynthesis may increase crop yield. Due to many limitations, plants use much less photosynthetic capacity than is theoretically possible. Plant nanobionics investigates nanoparticle application in living plants, which improves certain plant functions. We synthesized and tested nontoxic orange carbon dots (o-CDs) for the photosynthetic efficiency increase in maize (Zea mays L.). We applied o-CDs foliarly or by adding to the growth solution. The photosynthetic parameters and content of photosynthetic pigments were recorded. The total phenolic content (TPC) and total antioxidant activity (TAA) were measured to monitor the plant antioxidant response to o-CDs. The photosynthetic parameters' values were higher for foliar than for solution application. The 1 mg/L o-CDs applied foliarly and 5 mg/L in solution increased photosynthetic parameters in leaves. The o-CDs raised photosynthetic pigments. The TAA and TPC results indicate reduced antioxidant activity in the plant organs more exposed to o-CDs, depending on the way of application.",

AB  - Cerium oxide nanoparticles (nCeO(2)) have widespread applications, but they can be hazardous to the environment. Some reports indicate the toxic effect of nCeO(2) on tested animals, but literature data are mainly contradictory. Coating of nCeO(2) can improve their suspension stability and change their interaction with the environment, which can consequently decrease their toxic effects. Herein, the exopolysaccharides levan and pullulan, due to their high water solubility, biocompatibility, and ability to form film, were used to coat nCeO(2). Additionally, the monosaccharide glucose was used, since it is a common material for nanoparticle coating. This is the first study investigating the impact of carbohydrate-coated nCeO(2) in comparison to uncoated nCeO(2) using different model organisms. The aim of this study was to test the acute toxicity of carbohydrate-coated nCeO(2) on the bacterium Vibrio fischeri NRRL B-11177, the crustacean Daphnia magna, and zebrafish Danio rerio. The second aim was to investigate the effects of nCeO(2) on respiration in Daphnia magna which was performed for the first time. Finally, it was important to see the relation between Ce bioaccumulation in Daphnia magna and Danio rerio and other investigated parameters. Our results revealed that the coating decreased the toxicity of nCeO(2) on Vibrio fischeri. The coating of nCeO(2) did not affect the nanoparticles' accumulation/adsorption or mortality in Daphnia magna or Danio rerio. Monitoring of respiration in Daphnia magna revealed changes in CO2 production after exposure to coated nCeO(2), while the crustacean's O-2 consumption was not affected by any of the coated nCeO(2). In summary, this study revealed that, at 200 mg L-1 uncoated and carbohydrate-coated nCeO(2) are not toxic for the tested organisms, however, the CO2 production in Daphnia magna is different when they are treated with coated and uncoated nCeO(2). The highest production was in glucose and levan-coated nCeO(2) according to their highest suspension stability. Daphnia magna (D. magna), Danio rerio (D. rerio), Vibrio fischeri (V. fischeri)

AB  - Wels catfish (Silurus glanis, Linnaeus, 1758) is one of the most targeted species for recreational and commercial fishing in the Danube River, even though studies of behavior and movement patterns of Wels catfish in the Danube are rare. Wels catfish was caught downstream of Iron Gate II hydropower dam and tagged with an ultrasonic transmitter (Vemco Ltd, V16TP). Nine autonomous receivers (Vemco Ltd, VR 2W) recorded detections of spatial movement downstream of Iron Gate II dam between Serbia and Romania for almost two years, between the years 2015 and 2017. Our telemetry data found that Wels catfish exhibit relatively short movements within a maximum range (≈ 12 km), but as a territorial species most of the time it was recorded by the two receivers, close to the Iron Gate dam and location where it was caught. The longest displacement from the preferable place under Iron Gate II dam was migration to Romanian ship lock and turbines located in the right arm of the Danube River. Location under the river dam is already recognized as a place of aggregation of the fish and thus preference of predatory catfish is strongly connected with food availability. Our data revealed that dam and ship lock blocked further migration of this fish. The last signal received was during the winter 2017, which was a period with extremely low temperature and ice cover on the Danube River. Considering the fact that the ice displaced whole receiver deployment downstream the dam, we might conclude that the tagged catfish disappeared because of ice movement during the winter season. Results can be used for management ensuring habitat requirements and developing of restoration and conservation strategies.

AB  - The giant European catfish, Silurus glanis (total length = 200 cm; total weight approximate to 80 kg) was caught downstream of Iron Gate II hydropower dam (Danube River, 863 rkm) and tagged with an ultrasonic transmitter (V16TP; Vemco Ltd.) equipped with depth and temperature sensors. Changes in catfish diving behavior and temperature exposure were monitored over a period of roughly 2 years. Transmitter detections were recorded by nine autonomous receivers (VR2W, installed in 2015 between Serbia and Romania, as well as near Romanian shiplock and upstream Romanian turbines). The first signals were recorded on April 28, 2015 and the last on February 13, 2017. Altogether 59,355 and 59,175 detections of the catfish depth and water temperature were recorded, respectively. The greatest number of signals were recorded by the two receivers closest to the location where the catfish was caught, 72.3% and 27.1%, while only 0.6% of signals were recorded by other receivers. The mean catfish depth was 8.4 m, while minimum and maximum depths were 1.2 and 16.2 m. Results obtained showed that this catfish exhibited high site fidelity, while changes in depth at certain periods are possibly related to its search for prey and upstream migration during the spawning period. Hydropower dam and shiplock were obstacles on its migration upstream and telemetry studies could ensure habitat requirements and meet the development of restoration and conservation strategies for the fish resources in the future.

AB  - Plant organs that are exposed to continuous unilateral light reach in the steady-state a photogravitropic bending angle that results from the mutual antagonism between the photo- and gravitropic responses. To characterize the interaction between the two tropisms and their quantitative relationship we irradiated seedlings of Arabidopsis thaliana that were inclined at various angles and determined the fluence rates of unilateral blue light required to compensate the gravitropism of the inclined hypocotyls. We found the compensating fluence rates to increase with the tangent of the inclination angles (0?  lt  ?  lt  90? or max. 120?) and decrease with the cotangent (90? lt  ?  lt  180? or max. 120?of the inclination angles. The tangent dependence became also evident from analysis of previous data obtained with Avena sativa and the phycomycete fungus, Phycomyces blakesleeanus. By using loss-of function mutant lines of Arabidopsis, we identified EHB1 (enhanced bending 1) as an essential element for the generation of the tangent and cotangent relationships. Because EHB1 possesses a C2-domain with two putative calcium binding sites, we propose that the ubiquitous calcium dependence of gravi- and phototropism is in part mediated by Ca2+-bound EHB1. Based on a yeast-two-hybrid analysis we found evidence that EHB1 does physically interact with the ARF-GAP protein AGD12. Both proteins were reported to affect gravi- and phototropism antagonistically. We further showed that only AGD12, but not EHB1, interacts with its corresponding ARF-protein. Evidence is provided that AGD12 is able to form homodimers as well as heterodimers with EHB1. On the basis of these data we present a model for a mechanism of early tropism events, in which Ca2+-activated EHB1 emerges as the central processor-like element that links the gravi- and phototropic transduction chains and that generates in coordination with NPH3 and AGD12 the tangent / cotangent algorithm governing photogravitropic equilibrium.

AB  - Fish erythrocytes released from erythropoietic sites are immature. During circulation, they increase their own surface, while the cell body and nuclei begin to become more elliptical and less spherical during maturation. The relative abundance of different developmental stages represents an erythron profile which could be a more sensitive indicator of contamination than classic hematological indices. In this study, we analyzed blood smears of the common nase (Chondrostoma nasus) and vimba bream (Vimba vimba) with the main goal to identify the determinants of the developmental stage of erythrocytes. Based on parameters developmental stages, erythrocytes are categorized into immature, intermediate or mature. In this investigation we have used four classification methods: the Two Step Cluster analysis, the K-Means Cluster analysis, and Neural Networks-Multilayer Perceptron and an Ordinal Regression model. Our findings clearly justify that Multilayers Perceptron and OLR models are appropriate to classify the developmental stage of fish erythrocytes in both species.

In this study, we analyzed blood smears of the common nase (Chondrostoma nasus) and vimba bream (Vimba vimba) with the main goal to identify the determinants of the developmental stage of erythrocytes. Based on parameters developmental stages, erythrocytes are categorized into immature, intermediate or mature. In this investigation we have used four classification methods: the Two Step Cluster analysis, the K-Means Cluster analysis, and Neural Networks-Multilayer Perceptron and an Ordinal Regression model. Our findings clearly justify that Multilayers Perceptron and OLR models are appropriate to classify the developmental stage of fish erythrocytes in both species.",

AB  - A detailed analysis of the anesthetic-induced modulation of intracerebellar electrical activity is an important step to understand the functional brain responses to anesthesia. We examined the electrical activity recorded from different cortical layers: molecular layer (ML), Purkinje cell layer (PCL), granular layer (GL) and the white matter (WM) in the vermian part of rat cerebellar lobule V during Nembutal anesthesia using spectral and fractal analysis. Spectral analysis revealed a difference in the mean relative power of delta (0.1-4.0 Hz) and theta (4.1-8.0 Hz) frequencies through the cerebellar layers. Compared to the ML, delta activity increased significantly in the GL, while theta activity decreased in the GL and the WM. Fractal analysis revealed that the mean value of Higuchi's fractal dimension (HFD) increased, starting from the ML to the WM. Theta activity exhibited a negative correlation with the HFD value in the ML. In contrast, the gamma activity showed a positive correlation with the HFD value in the ML and the GL. The combined use of spectral and fractal analyses revealed that Nembutal displays different effects on rat cerebellar electrical activity, which largely depends on the neurochemical and electrophysiological organization of the cerebellar layers.

AB  - Aims: Electroencephalography (EEG) measures could be a potential markers for prediction of repetitive transcranial magnetic stimulation (rTMS) outcomes in depression. The aim of this study was to investigate the value of alpha asymmetric index (AAI) in predicting treatment response in two different protocols of rTMS in patients with intractable major depression. 
Methods: Patients with intractable major depression (n=34) were divided into two treatment groups underwent two different rTMS protocols. The first group  received ten sessions 20 Hz rTMS  The second group received 10 Hz rTMS . The EEGs were recorded in all subjects pre- and post-intervention using a 19-channel, 10-20 electrodes placement protocol. Hamilton depression rating scale-17 items (HDRS-17) was used to divide the patients into responders and non-responder. The AAI in prefrontal (Fp1-Fp2), frontal (F3-F4 and F7-F8), and temporal (T3-T4) regions were calculated and compared between pre- and post-intervention in each group and between the responder and non-responder groups.
Results: In the 20 Hz rTMS group responders, 6 patients responded to the treatment, whereas 10 Hz rTMS showed 8 responders. In the responders of 20 Hz rTMS, the AAI at Fp1-Fp2, F3-F4, and T3-T4significantly decreased after the intervention (P=0.011, P=0.042, and P=0.035). The responders of 10 Hz rTMS showed significant reduction in the AAI at Fp1-Fp2 and T3-T4 regions after intervention (P= 0.023 and P=0.044). 
Conclusions: It seems AAI at prefrontal and temporal region scould be used for prediction of treatment response, regardless of rTMS protocol.

AB  - Background and Aims: Neurofeedback treatment (NFT) may enhance attention performance in healthy individuals. This study investigated the effects of single session NFT on attention in healthy individuals performing a visual attention task. 
Methods: This was an open-label single-blinded trial conducted on 14 healthy university students (n=14; mean=23.35±0.58 years) of a major medical university in Iran. The subjects underwent a single session NFT while performing attentional network task (ANT). The NFT protocol was theta suppression/beta-1enhancement applied at Cz for 20 min. Before and immediately after NFT, EEG signals were recorded in subjects while performing ANT. EEGs were recorded using a 19 channel device and 10-20 placement protocol.
Results: The single session NFT increased the theta/beta-1 ratio in most of the electrode sites and the increase was statistically significant compared to the pre-intervention in the T6 site (p=0.011). The ratio decreased in just three sites of C3, Fz, and Cz, of them Fz showed a significant reduction (p=0.026). Contrary, the theta/alpha ratio decreased in most of the electrodes where the reductions were statistically significant in P3, P4, Cz, Pz (p<0.05), and C3 (p<0.01). The F7, F8, T3, and T4 showed no significant increased theta/alpha ratio. The central, temporal and occipital regions were involved in the NFT induced changes. Single NFT did not significantly change alerting, executive, or orienting networks of ANT.
Conclusions: Theta/beta-1 and theta/alpha ratios can be reliably used to assess NFT induced attention enhancement. However, single NFT did not induce clinical outcomes and repeated sessions seem necessary to modulate alerting, executive, or orienting networks of ANT.
