abstract = {Nanoparticles, like graphene oxide (GO), are particles with unique physiochemical properties that enable their wide application in various areas of life. The effects of GO on individual cell organelles like mitochondria and the effects of interactions are worth investigating, as they can activate multiple cellular processes, such as autophagy or apoptosis. Mitochondrial injury plays an essential role in the majority of cell death routines. In the project, we investigated cell health status measured as mitochondrial inner membrane depolarization, autophagy, and apoptosis induction during long-term GO administration in food (0.02 μg g−1 and 0.2 μg g−1 of food). Two unique Acheta domesticus strains that differ in life strategy were used: wild-type and long-lived at three different life stages (larva; young adult; mature adult). The changes in mitochondrial trans-membrane potential were marked in the wild-type strain. The autophagy was lower in all GO-treated groups in both strains, and the apoptosis was lower in both strains in the mature adult crickets. Low GO concentrations treatment for the whole life, despite mitochondrial dysfunction, may lead to inhibition of autophagy and apoptosis by arresting the cell cycle for the duration of repair, and other repair tools are involved in the process of restoring homeostasis. © 2024 The Authors},

abstract = {Graphene oxide nanoparticles (GO) (have promising properties for; electronics; energy; medicine; water purification; agriculture and food production industry. However; their potentially hazardous effects are still not satisfactorily recognized; so they are often included in the group of contaminants of emerging concern. Therefore; the aim of this investigation was to assess the potentially harmful effects of orally administered GO on the digestive enzyme activities of the house crickets Acheta domesticus. The activity of digestive enzymes was measured using the API®ZYM test and the results were compared in relation to the insect age group (Larvae; Adult Young and Adult Mature) and previous selection towards longevity (‘long living’ vs ‘wild’ strains). General analysis; encompassing all digestive enzymes simultaneously; as well as an analysis performed for individual enzyme subgroups; revealed that both factors and their interactions significantly modified the activity of digestive enzymes of A. domesticus. The most pronounced effect was connected with the age factor. The study revealed that the Adult Young age group was the most sensitive; in this group; the activity of digestive enzymes was; in general; decreased in comparison with the control group; while the remaining group did not respond to GO with a similar intensity. In turn; the inter-strain comparisons demonstrated different response patterns to the GO. The control enzymatic activity of the insects from long living’ strain was; in general; higher than in the ‘wild strain’; however; it was significantly decreased in the GO-exposed groups; while in the ‘wild’ strain; the activity remained relatively homogenous. Additionally; the tendency was more pronounced in Adult Young than in the remaining age groups. The potential toxicity of GO requires further investigation; mainly with a focus on the composition and functioning of gut microbiotas. © 2024 The Authors},

abstract = {The use of nanoparticles in the industry carries the risk of their release into the environment. Based on the presumption that the primary graphene oxide (GO) toxicity mechanism is reactive oxygen species production in the cell, the question arises as to whether well-known antioxidants can protect the cell or significantly reduce the effects of GO. This study focused on the possible remedial effect of vitamin C in Acheta domesticus intoxicated with GO for whole lives. The reproduction potential was measured at the level of Vitellogenin (Vg) gene expression, Vg protein expression, hatching success, and share of nutrition in the developing egg. There was no simple relationship between the Vg gene’s expression and the Vg protein content. Despite fewer eggs laid in the vitamin C groups, hatching success was high, and egg composition did not differ significantly. The exceptions were GO20 and GO20 + Vit. C groups, with a shift in the lipid content in the egg. Most likely, ascorbic acid impacts the level of Vg gene expression but does not affect the production of Vg protein or the quality of eggs laid. Low GO concentration in food did not cause adverse effects, but the relationship between GO toxicity and its concentration should be investigated more thoroughly. © 2024 by the authors.},

abstract = {The long-term exposure effects of nanodiamonds (NDs), spanning an organism's entire lifespan and continuing for subsequent generation, remain understudied. Most research has focused on evaluating their biological impacts on cell lines and selected organisms, typically over short exposure durations lasting hours or days. The study aimed to assess growth, mortality, and digestive functions in wild (H) and long-lived (D) strains of Acheta domesticus (Insecta: Orthoptera) after two-generational exposure to NDs in concentrations of 0.2 or 2 mg kg−1 of food, followed by their elimination in the third generation. NDs induced subtle stimulating effect that depended on the strain and generation. In the first generation, more such responses occurred in the H than in the D strain. In the first generation of H strain insects, contact with NDs increased survival, stimulated the growth of young larvae, and the activity of most digestive enzymes in mature adults. The same doses and exposure time did not cause similar effects in the D strain. In the first generation of D strain insects, survival and growth were unaffected by NDs, whereas, in the second generation, significant stimulation of those parameters was visible. Selection towards longevity appears to support higher resistance of the insects to exposure to additional stressor, at least in the first generation. The cessation of ND exposure in the third generation caused potentially harmful changes, which included, e.g., decreased survival probability in H strain insects, slowed growth of both strains, as well as changes in heterochromatin density and distribution in nuclei of the gut cells in both strains. Such a reaction may suggest the involvement of epigenetic inheritance mechanisms, which may become inadequate after the stress factor is removed. © 2023 Elsevier Ltd},

Cell death processes were assessed by light and transmission electron microscopy, terminal deoxynucleotidyl transferase dUTP nick end labeling(TUNEL), and cytometric analyses.

Elevated programmed cell death intensity levels decreased after several generations, indicating tolerance of individuals to cadmium in the diet and verifying the first hypothesis; however, testing the second hypothesis indicated that the number of generations depended not only on pressure intensity, but also on cell death type, since levels of autophagy remained increased for a minimum of 12 generations. © The Author(s) 2023.

abstract = {The use of nanoparticles like graphene oxide (GO) in nanocomposite industries is growing very fast. There is a strong concern that GO can enter the environment and become nanopollutatnt. Environmental pollutants’ exposure usually relates to low concentrations but may last for a long time and impact following generations. Attention should be paid to the effects of nanoparticles, especially on the DNA stability passed on to the offspring. We investigated the multigenerational effects on two strains (wild and long-lived) of house cricket intoxicated with low GO concentrations over five generations, followed by one recovery generation. Our investigation focused on oxidative stress parameters, specifically AP sites (apurinic/apyrimidinic sites) and 8-OHdG (8-hydroxy-2′-deoxyguanosine), and examined the global DNA methylation pattern. Five intoxicated generations were able to overcome the oxidative stress, showing that relatively low doses of GO have a moderate effect on the house cricket (8-OHdG and AP sites). The last recovery generation that experienced a transition from contaminated to uncontaminated food presented greater DNA damage. The pattern of DNA methylation was comparable in every generation, suggesting that other epigenetic mechanisms might be involved. © 2023 by the authors.},

Sensitivity to GO of immature, or with different survival strategy, individuals has not been studied so far. Therefore, in the present research, we focused on the GO genotoxic effects, examining selected parameters of DNA damage (total DNA damage; double-strand breaks—DSB; 8-hydroxy-2′-deoxyguanosine-8-OHdG; abasic site—AP sites), DNA damage response parameters, and global methylation in the model organism Acheta domesticus. Special attention was paid to various life stages and lifespans, using wild (H), and selected for longevity (D) strains. DNA damage was significantly affected by stage and/or strain and GO exposure. Larvae and young imago were generally more sensitive than adults, revealing more severe DNA damage. Especially in the earlier life stages, the D strain reacted more intensely/inversely than the H strain. In contrast, DNA damage response parameters were not significantly related to stage and/or strain and GO exposure. Stage-dependent DNA damage, especially DSB and 8-OHdG, with the simultaneous lack or subtle activation of DNA damage response parameters, may result from the general life strategy of insects. Predominantly fast-living and fast-breeding organisms can minimize energy-demanding repair mechanisms. © 2022 by the authors.},

abstract = {Nanodiamonds (NDs) are considered a material with low toxicity. However, no studies describe the effects of ND withdrawal after multigenerational exposure. The aim was to evaluate ND exposure (in the 1st and 2nd generations) effects at low concentrations (0.2 or 2 mg kg−1) and withdrawal (in the 3rd generation) in the wild (H) and longevity-selected (D) model insect Acheta domesticus. We measured selected oxidative stress parameters, immunity, types of cell death, and DNA damage. Most of the results obtained in the 1st generation, e.g., catalase (CAT), total antioxidant capacity (TAC), heat shock proteins (HSP70), defensins, or apoptosis level, confirmed no significant toxicity of low doses of NDs. Interestingly, strain-specific differences were observed. D-strain crickets reduced autophagy, the number of ROS+ cells, and DNA damage. The effect can be a symptom of mobilization of the organism and stimulation of physiological defense mechanisms in long-living organisms. The 2nd-generation D-strain insects fed ND-spiked food at higher concentrations manifested a reduction in CAT, TAC, early apoptosis, and DNA damage, together with an increase in HSP70 and defensins. ROS+ cells and cells with reduced membrane potential and autophagy did not differ significantly from the control. H-strain insects revealed a higher number of ROS+ cells and cells with reduced membrane potential, decreased CAT activity, and early apoptosis. Elimination of NDs from the diet in the 3rd generation did not cause full recovery of the measured parameters. We noticed an increase in the concentration of HSP70 and defensins (H-strain) and a decrease in apoptosis (D-strain). However, the most visible increase was a significant increase in DNA damage, especially in H-strain individuals. The results suggest prolonged adverse effects of NDs on cellular functions, reaching beyond “contact time” with these particles. Unintentional and/or uncontrolled ND pollution of the environment poses a new challenge for all organisms inhabiting it, particularly during multigenerational exposure. © 2022 The Authors},

Its exogenicity and low concentrations mean that it can be regarded as one of the key regulatory molecules at the cellular as well as physiological level. It has been shown to have a number of essential functions, such as in the production of other biologically active molecules. The main objective of this project was to investigate the effects of a high monosaccharide diet (HMD) on a hemimetabolic insect—house cricket (Acheta domesticus) and a mutant strain with impaired visual pigment synthesis (closely related to the tryptophan and kynurenine (KYN) metabolic pathway)—white eye. This study was aimed at determining the effects of glucose and fructose on cricket development and biochemical composition. A parallel goal was to compare the response of both cricket strains to HMD. ELISA assays indicated dysfunction of the TRP-KYN pathway in white strain insects and an elevated KYN/TRP ratio. Biochemical analyses demonstrated the effects of HMD mainly on fat and glycogen content. A decrease in food intake was also observed in the groups on HMD. However, no changes in imago body weight and water content were observed. The results of the study indicate a stronger response of the white strain to HMD compared to the wild-type strain. At the same time, a stronger detrimental effect of fructose than of glucose was apparent. Sex was found to be a modulating factor in the response to HMD. © 2021, The Author(s).},

After 8 weeks on high fat, high sugar diet (HFS) or control diets (CD), Sprague–Dawley rats underwent DJOS or SHAM (control) surgery. For the next 8 weeks after the surgery, half of DJOS and SHAM-operated animals were kept on the same diet as before, and half had a diet change.

Fetuin-B, growth differentiation factor-15 (GDF-15), pentraxin 3 (PTX3) plasma levels were analyzed. DJOS surgery had a beneficial effect on oral glucose tolerance test (OGTT) results and the area under the curve (AUCOGTT). The OGTT results depended on the time elapsed after the surgery, the type of diet used, the surgery performed, and the interaction between these factors. DJOS bariatric surgery reduced fetuin-B and GDF15 plasma levels. Interaction between the type of surgery performed and diet used influenced the fetuin-B and PTX-3 plasma levels.

abstract = {The anthropogenic activities may lead to accumulation of graphene oxide (GO) pollution in the environment. Organisms exposed to chronic or multigenerational GO intoxication can present reproduction depletion. Vitellogenin (Vg) has been used as a parameter for evaluating female fertility due to its importance in embryo nutrition. In this study, we used a promising model organism, Acheta domesticus, which was intoxicated with GO in food for three generations. The aim of the study was to investigate the process of Vg synthesis in crickets depending on the exposure time, GO concentration, and age of the females. The results revealed that chronic GO intoxication had adverse effects on the Vg expression pattern. The 1st generation of insects showing low Vg expression was most affected. The 2nd generation of A. domesticus presented a high Vg expression. The last investigated generation seemed to cope with stress caused by GO, and the Vg expression was balanced. We suggest that the epigenetic mechanisms may play a role in the information transfer to the next generations on how to react to the risk factor and keep reproduction at a high rate. We suspect that chronic GO intoxication can disturb the regular formation of the Vg quaternary structure, resulting in consequences for developing an embryo. © 2021 Elsevier Ltd},

abstract = {The aim of this study was to determine the role of Diabrotica virgifera virgifera (western corn rootworm; WCR) as a potential insect vector of the pathogenic bacterium Pantoea ananatis. The experiment included a greenhouse test to investigate if WCR was able to transfer the pathogenic bacteria from infected to healthy maize plants. Adult WCR specimens collected from maize fields near Rzeszów were used in the experiment. The plant materials were sweetcorn plants of the Waza variety. Pure cultures of previously verified P. ananatis strain M241 were the source of the inoculum. Insects caught under natural conditions were incubated in an isolator containing pathogen-negative plants. Randomly selected insects were then examined for the presence of bacterial pathogens of maize in their digestive tract. Pathogen-negative insects were used in the next stage of the experiment still carried out in isolators, in which the insects foraged on maize seedlings previously infected with P. ananatis. The control group consisted of healthy, uninfected insects and plants. After the incubation period, the presence of bacterial pathogens in the gastrointestinal tract of the WCR specimens was confirmed. Subsequent insects that acquired P. ananatis were bred on pathogen-negative maize plants. After incubation, the presence of pathogenic bacteria in the body of the examined WCR beetles was confirmed, and the presence of symptoms of the bacterial disease was noted on maize plants, fulfilling Koch's postulates and indicating that the WCR is a vector of P. ananatis on maize plants. This is the first report on the vectorization of P. ananatis by D. virgifera globally. © 2020 Elsevier Ltd},

abstract = {Mitochondria are organelles that play a crucial role in cell physiology, cell death, and aging. They are among the first responders to different stressors that originate from the environment. Cadmium as a heavy metal affects different levels of body organization: from organs through tissues and cells to organelles. Based on our previous research results, we decided to check how the exposure to cadmium affects the functioning of mitochondria in different organs of soil living centipede Lithobius forficatus. The activity of mitochondria in somatic and germ cells has been analyzed using transmission electron microscopy (TEM), confocal microscopy, and flow cytometry. Changes in the mitochondrial membrane potential and mitochondrial dismutase (MnSOD) activity in relation to the accumulation of reactive oxygen species (ROS) caused by cadmium exposure have been studied. Individuals were divided into 3 experimental groups depending on cadmium concentration in soil. Changes in mitochondrial ultrastructure caused by cadmium are tissue-dependent and associated with an increase of ROS levels. The system of ROS and MnSOD activation works more efficiently in the case of gonads than in the digestive system. While the short-term cadmium exposure alters the fine structure of both the somatic and germ-line cells in gonads, the long-term cadmium exposure causes mitochondrial ultrastructure regeneration. © 2021 The Author(s).

abstract = {Variability of stress proteins concentration in caged carp exposed to transplantation experiment model dam reservoir was caused only by natural (climatic and biological) conditions. Thus, the reference data of stress proteins concentration range in young carp individuals were obtained. Metallothionein, HSP70 and HSP90 protein concentrations as biomarkers were assayed in the livers, gills and muscles of six-month-old (summer) or nine-month-old (autumn) carp individuals in relation to the site of encaging, season (summer or autumn), the term of sampling (1; 2 or 3 weeks after the transplantation) and tissue. Physicochemical analyses of the condition of water as well as pollution detection were conducted during each stage of the experiment. As the result of this study, the range of the variability of the stress protein concentration in young carp individuals was obtained. According to the analyses of the aquatic conditions of a reservoir with no detectable pollutants, we conclude that the variability in the stress protein concentration levels in the groups that were compared is solely the result of the natural conditions. Future regular monitoring of the reservoir using the transplantation method and young carp individuals will be both possible and reliable. Moreover, the range of variability in the stress protein concentrations that were measured in the young C. carpio individuals acquired from the model dam reservoir in relation to all of the studied factors may be applied in the monitoring of any other similar reservoir. © 2021.

So, the aim of this study was to compare of the development traits, total antioxidant capacity, lipid peroxidation, RSSR to RSH ratio and the concentration of carbohydrates, glycogen, lipids and proteins in whole individuals (larvae or pupae) of Spodoptera exigua originating from two strains: control and selected over 120 generations with sublethal metal concentration (44 Cd mg per dry weight of diet). Generally, the increase of the protein, carbohydrates, glycogen concentration and lipid peroxidation decrease with age of the larvae were found. Revealed cases of a higher mobilisation of carbohydrates and proteins, and changes in total antioxidant capacity or lipid peroxidation, in individuals being under metal exposure, occurred in strain-depended mode. Short-term Cd exposure effect was connected with possible higher engagement of proteins and glycogen in detoxification processes, but also higher concentration of lipid peroxidation.

abstract = {Autophagy is a natural process that aims to eliminate malfunctioning cell parts, organelles or molecules under physiological conditions. It is also induced in response to infection, starvation or oxidative stress to provide energy in case of an energy deficit. The aim of this 2-dimensional study was to test if, and if so, how, this process depends on the concentration of cadmium in food (with Cd concentrations from 0 to 352 μg of Cd per g of food (dry weight)—D1 dimension) and the history of selection pressure (160 vs 20 generations of exposure to Cd—D2 dimension). For the study, the 5th instar larvae of a unique strain of the moth Spodoptera exigua that was selected for cadmium tolerance for 160 generations (44 μg of Cd per g of food (dry weight)), as well as 20-generation (11; 22 and 44 μg of Cd per g of food (dry weight)) and control strains, were used. Autophagy intensity was measured by means of flow cytometry and compared with life history parameters: survivability and duration of the 3rd larval stage. The highest values of autophagy markers were found in the groups exposed to the highest Cd concentration and corresponded (with a significant correlation coefficient) to an increased development duration or decreased survivorship in the respective groups. In conclusion, autophagy is probably initiated only if any other defense mechanisms, e.g., antioxidative mechanisms, are not efficient. Moreover, in individuals from pre-exposed populations, the intensity of autophagy is lower. © 2020, The Author(s).},

abstract = {Human activity is a serious cause of extensive changes in the environment and a constant reason for the emergence of new stress factors. Thus, to survive and reproduce, organisms must constantly implement a program of adaptation to continuously changing conditions. The research presented here is focused on tracking slow changes occurring in Spodoptera exigua (Lepidoptera: Noctuidae) caused by multigenerational exposure to sub-lethal cadmium doses. The insects received food containing cadmium at concentrations of 5, 11, 22 and 44 μg per g of dry mass of food. The level of DNA stability was monitored by a comet assay in subsequent generations up to the 36th generation. In the first three generations, the level of DNA damage was high, especially in the groups receiving higher doses of cadmium in the diet. In the fourth generation, a significant reduction in the level of DNA damage was observed, which could indicate that the desired stability of the genome was achieved. Surprisingly, however, in subsequent generations, an alternating increase and decrease was found in DNA stability. The observed cycles of changing DNA stability were longer lasting in insects consuming food with a lower Cd content. Thus, a transient reduction in genome stability can be perceived as an opportunity to increase the number of genotypes that undergo selection. This phenomenon occurs faster if the severity of the stress factor is high but is low enough to allow the population to survive. © 2020 Elsevier B.V.},

abstract = {The increased use of graphene oxide (GO) raises worrisome questions regarding its possible threat to various ecosystems. Invertebrates represent valuable organisms for environmental studies. The lifespan can influence the ability to cope with toxins, especially those that act via oxidative stress. Two strains of Acheta domesticus, which are selected for longevity, were tested. The main aim was to investigate how GO, when administrated in food, affects: the condition of cells, DNA stability, ROS generation and the reproduction potential (the Vitellogenin (Vg) protein expression). The “recovery effect” – after removing GO from the diet for 15 days – was also measured. The results revealed different responses to GO in the wild (H) and long-living (D) strains. The D strain had a higher catalase activity compared to the H strain on the 25th day of the imago stage. Removing GO from the food resulted in a decrease in the catalase activity to the level of the control. On the 5th day of the imago stage, the H strain had a higher cell mortality than the D strain in the GO-intoxicated groups. There was more DNA damage in the H strain compared to the long-living strain. A remedial effect was seen after the GO was removed from the diet. The total Vg protein expression was higher in the H strain and lower in the D strain. The results indicated a GO concentration-dependent outcome. In both strains, removing the GO from the food led to a high Vg expression. The Vg expression after GO treatment, particularly translation and post-translational processing, should be studied in detail in the future. The D strain of crickets had more specialized mechanisms for maintaining homeostasis than the H strain. Organisms can fight off negative effects of GO, especially when they have systems that are well developed against oxidative stress. © 2020 Elsevier B.V.},

To achieve this, larvae originating from three laboratory populations of S. exigua (control strain - C; cadmium-intoxicated for 135 generations strain - Cd; and control strain intoxicated with Cd for 1 generation - CCd) were additionally exposed to zinc in three concentrations (Zn1; 400 μg Zn·g−1 dry mass of food; Zn2; 200 μg Zn·g−1 dry mass of food; Zn3; 100 μg Zn·g−1 dry mass of food). As the markers of toxicity, a life history traits (the duration of L4 and L5 stages), cellular (DNA damage indices) and biochemical parameters (ADP/ATP ratio and ATP and HSP70 concentrations) were chosen. The duration of larval stages of Zn supplemented larvae was prolonged, while cellular and biochemical indicators, in general, appeared to be lower in comparison to the insects from respective reference groups in each laboratory populations. Moreover, the range of the differences depended on zinc concentration in food. We can suspect that zinc supplementation contributed to the protection of S. exigua individuals against negative effects of cadmium intoxication, probably at the cost of growth rate. Significant differences in the response pattern between insects from different laboratory populations indicate that the influence of additional stress factors is dependent on the overall condition of animals and their previous adaptation to other stressors. © 2019 Elsevier Ltd},

abstract = {The aim of this study was to investigate whether the cadmium tolerance developed in the beet armyworm Spodoptera exigua selected for over 150 generations may be related to synthesis of the stress proteins metallothioneins (Mts) and 70 kDa heat shock proteins (HSP70). To achieve this, six S. exigua strains (control; k), 150-generation Cd exposure strain (cd), and four 18-generation Cd exposure strains differing in Cd concentration (cd44; cd22; cd11; cd5) were reared. Stress protein level was measured in the midgut of the 5th larval stage after 1–6, 12 and 18 generations. Cd contents was measured in the pupae. Unlike Cd concentration, which depended on metal contents in food but was not generation-dependent, the pattern of Mts and HSP70 concentrations changed in experimental strains from generation to generation. Stress protein levels in the insects exposed to the highest Cd concentration (the same as in the 150-generation Cd exposure strain), initially higher than in the control strain, after the 12th generation did not differ from the level measured in the control strains. It seems therefore that stress proteins play a protective role in insects of lower tolerance to cadmium. The tolerance developed during multigenerational exposure probably relies on mechanisms other than Mt and HSP70 synthesis. © 2019 Elsevier Inc.},

Therefore, the aim of this study was to check whether the acute laboratory exposure of common carp juveniles to a mixture of ibuprofen, sodium dodecyl sulphate (SDS), dimethyl sulfoxide (DMSO) and 17 α-ethynylestradiol in increasing concentrations, modifies the levels of innate immunity (lysozyme; C-reactive protein) as well as general stress (metallothioneins; heat shock proteins HSP70) markers in brain, liver, gills, spleen and mucus. The levels of the markers were measured by an immunodetection technique. Not only do the pharmaceuticals and household chemicals impair immunological reactions of young carp in various tissues but also do that in a concentration-dependent manner in the liver, gills, spleen and mucus. This has a very important implication, since it may result in higher sensitivity of young fish to pathogens due to energy allocation to defence processes. The comparisons of the pattern of stress reactions in the studied organ samples indicated that mucus appeared to be a good, non-invasive material for monitoring of environmental state and fish conditions. © 2019},

abstract = {The middle region of the digestive system, the midgut of freshwater shrimp Neocaridina davidi is composed of a tube-shaped intestine and the hepatopancreas formed by numerous caeca. Two types of cells have been distinguished in the intestine, the digestive cells (D-cells) and regenerative cells (R-cells). The hepatopancreatic tubules have three distinct zones distinguished along the length of each tubule-the distal zone with R-cells, the medial zone with differentiating cells, and the proximal zone with F-cells (fibrillar cells) and B-cells (storage cells). Fasting causes activation of cell death, a reduction in the amount of reserve material, and changes in the mitochondrial membrane potential. However, here we present how the concentration of ROS changes according to different periods of fasting and whether re-feeding causes their decrease. In addition, the activation/deactivation of mitochondrial superoxide dismutase (MnSOD) was analyzed. The freshwater shrimps Neocaridina davidi (Crustacea; Malacostraca; Decapoda) were divided into experimental groups: animals starved for 14 days, animals re-fed for 4, 7, and 14 days. The material was examined using the confocal microscope and the flow cytometry. Our studies have shown that long-term starvation increases the concentration of free radicals and MnSOD concentration in the intestine and hepatopancreas, while return to feeding causes their decrease in both organs examined. Therefore, we concluded that a distinct relationship between MnSOD concentration, ROS activation, cell death activation and changes in the mitochondrial membrane potential occurred.

abstract = {Long lasting exposure of animals to stressing factor may lead to the selection of population able to cope with the stressor at lower cost than unexposed individuals. The aim of this study was to assess whether 130-generational selection of a beet armyworm to cadmium in food might have induced tolerance also to other stressors. The potential tolerance was assessed by means of unspecific stress markers: HSP70 concentration, DNA damage level, and energy budget indices in L5 larval instars of beet armyworm. The animals originated from Cd-exposed and control strains exposed additionally in a short-term experiment to high/low temperature or pesticide—spinosad. The application of the additional stressors caused, in general, an increase in the levels of studied parameters, in a strain-dependent manner. The most significant increase was found in HSP70 level in the individuals from the Cd-strain exposed to various spinosad concentration. Therefore, multigenerational contact with cadmium caused several changes that enable the insect to survive under a chronic stress, preparing the organism to the contact with an additional, new stressor. This relationship may be described as a sort of cross tolerance. This may, possibly, increase the probability of population survivorship and, at the same time, decrease the efficiency of pesticide-based plant protection efforts. © 2017, The Author(s).},

abstract = {In the case of the pests inhabiting metal polluted or fields where the use of pesticides is common, a natural selection of resistant individuals can occur. This may pose serious problems for humans, agriculture, as well as the economies of many countries. In this study, the hypothesis that multigenerational (120 generations) exposure to cadmium of a beet armyworm population could be a selecting factor toward a more efficient DNA protection was verified. The hemocytes of individuals from two culture strains (control and Cd-exposed) were treated with H2O2 (a DNA-damaging agent) or PBS (reference). The level of DNA damage was assessed using the Comet assay immediately and 5, 15 and 30 min. after the treatment. The immediate result of the contact with H2O2 was that the level of DNA damage in the hemocytes of the insects from both strains increased significantly. However, in the cells of the Cd-exposed individuals, the level of DNA damage decreased over time, while in the cells from the control insects it remained at the same level with no evidence of repair. These results suggest that efficient defense mechanisms may exist in the cells of insects that have prolonged contact with cadmium. Some evolutionary and trade-off aspects of the phenomenon are discussed. In a wider context, comparing the results obtained in the laboratory with field studies may be beneficial for understanding basic mechanisms of the resistance of an organism. To summarize, the high potential for the repair of DNA damage that was observed in the insects from the cadmium strain may confirm the hypothesis that multigenerational exposure to that metal may possibly contribute to the selection of insects that have a wider tolerance to oxidative stress. However, our investigations of polymorphism using AFLP did not reveal differences between the two main insect strains. © 2016 Augustyniak et al.

The study was conducted in 2009/10 in the south-eastern part of Poland. The D. virgifera beetles were captured using two types of trap: pheromone (PTs) and floral-baited (FTs). Significant differences in beetle counts were found between: (i) the first and second year of the study (higher in 2009 than in 2010); (ii) the varieties of maize and their different growth stages; (iii) early and medium-late varieties of maize. Initially, depending on the availability of maize silk and pollen, the most numerous D. virgifera beetles were found on the early varieties followed by the medium-late varieties. The study also revealed a significant difference in the performance of the two types of trap used to monitor the number of adults, particularly during the initial period when arrival rates were high. Pheromone traps were more effective in catching D. virgifera beetles, especially during the flowering stage of maize. Floral-baited traps were most effective at the end of the active growth of maize, when the preferred food of D. virgifera was unavailable. © Cambridge University Press 2015.},

Increasing PQ concentrations applied either directly to the brain cells suspension (10; 50; and 250. μM PQ final concentration - in vitro protocol) or indirectly (50; 250; and 1250. μM PQ final concentration - in vivo protocol) provoked significant increase of oxidative damage to DNA (higher median TDNA and OTM values). The damage increased with time of exposure (0; 5; 15; and 30. min) following in vitro application, but decreased in longer interval (3 vs 24. h) after in vivo administration of paraquat.

abstract = {The western corn rootworm, Diabrotica virgifera virgifera LeConte (Coleoptera: Chrysomelidae) is an important pest of maize. The diet of the D. virgifera imago is rich in starch and other polysaccharides present in cereals such as maize. Therefore, knowledge about enzymes involved in digestion of such specific food of this pest seems to be important. The paper shows, for the first time, the activities of main glycolytic enzymes in the midgut of D. virgifera imago: endoglycosidases (α-amylase; cellulase; chitinase; licheninase; laminarinase); exoglycosidases (α- and β-glucosidases; α- and β-galactosidases) and disaccharidases (maltase; isomaltase; sucrase; trehalase; lactase; and cellobiase). Activities of α-amylase, α-glucosidase, and maltase were the highest among assayed endoglycosidases, exoglycosidases, and disaccharidases, respectively. This indicates that in the midgut of D. virgifera imago a-amylase, α-glucosidase and maltase are important enzymes in starch hydrolysis and products of its digestion. These results lead to conclusion that inhibition of most active glycolytic enzymes of D. virgifera imago may be another promising method for chemical control of this pest of maize. © The Author 2015.

The highest level of expression was exhibited by Hsp90, while Hsp70 showed the lowest level of expression. There were no statistically significant differences in the expressions of Hsp40 and Hsp70 after the pesticide treatment. The highest concentration of Hsp90 was found in beetles 24 hours after the exposition to dimethoate, while the lowest was observed in insects 1 hour after the treatment. Hsps play a role in response to organophosphorous pesticide in Leptinotarsa decemlineata (Say; 1824), but there is not any simple correlation between Hsp levels and time of exposition.

abstract = {The phenomenon of metal hyperaccumulation by plants is often explained by a pathogen or herbivore defense hypothesis. However, some insects feeding on metal hyperaccumulating plants are adapted to the high level of metals in plant tissues. Former studies on species that feed on the leaves of Berkheya coddii Roessler 1958 (Asteraceae), a nickel-hyperaccumulating plant, demonstrated several protective mechanisms involved in internal distribution, immobilization, and elimination of Ni from the midgut and Malpighian tubules. These species are mainly coleopterans, including the lady beetle, Epilachna nylanderi (Mulsant 1850) (Coleoptera: Coccinellidae), collected from the ultramafic ecosystem near Barberton in South Africa. By performing particle-induced X-ray emission microanalysis elemental microanalysis (PIXE), this study examined whether Ni may be harmful to internal body systems that decide on insect reactivity (central nervous system [CNS]), their reproduction, and the relationships between Ni and other micronutrients. Data on elemental distribution of nine selected elements in target organs of E. nylanderi were compared with the existing data for other insect species adapted to the excess of metals. Micro-PIXE maps of seven regions of the CNS showed Ni mainly in the neural connectives, while cerebral ganglia were better protected. Concentrations of other bivalent metals were lower than those of Ni. Testis, compared with other reproductive organs, showed low amounts of Ni. Zn was effectively regulated at physiological dietary levels. In insects exposed to excess dietary Zn, it was also accumulated in the reproductive organs. Comparison of E. nylanderii with other insects that ingest hyperaccumulating plants, especially chrysomelid Chrysolina clathrata (Clark) (Coleoptera: Chrysomelidae), showed lower protection of the CNS and reproductive organs. © The Author 2014.

Among grazers of Ni-hyperaccumulating Berkheya coddii, some beetles tolerate Ni (Chrysolina clathrata; former name Chrysolina pardalina; Epilachna nylanderi). The adaptive mechanisms against Ni toxicity were studied in these species using micro-PIXE quantitative elemental mapping and by microscopy techniques. Distinct differences were found in mechanisms used for Ni-elimination in both species. Functional comparisons and quantification of data extracted from selected micro-areas in target organs responsible for metal circulation (digestive tract and Malpighian tubules) were made. Similar detoxification mechanism is used against metals through spheric granules, which in E. nylanderi are formed mainly in the midgut, while in C. clathrata in Malpighian tubules and midgut. Elemental maps showed positive correlations of Ni and Zn in Malpighian tubules of E. nylanderi without such effect in C. clathrata. Quantitative relations of K+ and Cl- indicate higher osmotic pressure increasing reabsorption of water necessary for Ni transportation to the intestine lumen and further rejection outside the body. © 2011 John Wiley & Sons, Ltd.},

The main aim of our work was to assess the relationship between the age of female grasshoppers originating from variously polluted habitat and the hsp70 level in their progeny. Possible reasons for population variation in hsp70 levels were discussed. The hsp70 level in the offspring's body depended on the place of origin. The strongest expression of hsp70 was found in the bodies of larvae hatching from the eggs laid by young females from Pilica (reference site). In contrast, a low initial level of hsp70 in larvae from polluted sites, especially in young females' progeny, was observed. The application of zinc during diapause influenced the hsp70 level in grasshopper larvae; however, the direction of the changes depended on the insects' place of origin. In larvae from the reference site, and also (but to a lesser degree) from Olkusz, the increase in the hsp70 level after zinc treatment was most pronounced. Whereas in grasshoppers from Szopienice, zinc (in 100 μg g-1 dry weight of sand) did not change the hsp70 level, or (in 500 μg g-1 dry weight of sand) caused a reduction in hsp70. The differences may result from maternal effects; however, possible adaptation also cannot be excluded. To confirm this statement further studies are needed. © 2009 Elsevier Ltd.

abstract = {This study is focused on recognizing how the functional role of hepatopancreas, the main metal storage organ in woodlice, is affected by the excess of nickel, a toxic element to soil invertebrates. Chronic Ni toxicity (24 weeks) was studied on four groups of woodlice kept on dry shredded maple leaves contaminated with Ni at average concentrations of 0.1 μg g-1 (control), 8.0 μg g-1 (Ni1), 75 μg g-1 (Ni2) and 270 μg g-1(Ni3) dry weight. Micro-PIXE mapping of elemental distribution in the hepatopancreas of the Porcellio scaber woodlice was used to study relations between nickel and other elements in individuals exposed to different metal concentrations in the diet. Data were processed using GeoPIXE II software. Transmission electron microscopy (TEM) was used to check the relations between ultrastructural changes in hepatopancreatic cells and nickel tissue burden. Elemental mapping showed a dose-related nickel bioaccumulation in the hepatopancreas at concentrations from 3 μg g-1 (uncontaminated control animals) to nearly 840 μg g-1 (Ni3). Generally, nickel was distributed uniformly in small aggregations. A combined evaluation of elemental maps and electronograms showed that aggregations of nickel in arbitrarily selected micro-areas in PIXE maps could be the granular structures observed in TEM electronograms. The mechanism of Ni sequestration in the hepatopancreas could be similar to this used for cadmium or lead. The sequences of ultrastructural changes, which follow the increased burdens of Ni in the hepatopancreatic cells, were: the increase of intracellular electron-dense granules, increase in the number of myelin-like structures, intensified mitochondrial swelling and appearance of concentrically arranged, rough endoplasmic reticulum. © 2007 Elsevier B.V.

abstract = {Studies on toxic effects of nickel were conducted in a chronic experiment on four groups of woodlice Porcellio scaber kept for 24 weeks on dry maple leaves containing Ni 0.1 (control), 8 (Ni1), 75 (Ni2) and 270 (Ni3) μg g-1 dry weight. Micro-PIXE elemental mapping complemented by proton backscattering was used to study relations between Ni and other elements in the hindgut. Data processed with GeoPIXE II demonstrated the highest amount of Ni in the hindgut of (Ni2) woodlice followed by the highest levels of Ca, Mn and Fe. Inverse relationship was observed between hindgut concentration of Zn and the Ni levels in the diet. Transmission electron microscopy (TEM) was used for checking possible relations between the ultrastructure of the hindgut epithelial cells and nickel tissue burden. In animals from all the "nickel groups" a series of ultrastructural alterations (disturbances in apical and basal membrane labyrinth and presence of lysosome-like structures with electron-dense material in the cytoplasm) was identified when compared with control woodlice. Large mitochondria with distinctly visible electron-dense precipitations inside them were present in the cells of animals from groups (Ni1) and (Ni3). In addition, a disturbed internal mitochondrial membrane system was observed in the cells of the (Ni2) woodlice group. © 2007 Elsevier B.V. All rights reserved.},

abstract = {Berkheya coddii Roessler (Asteraceae), an endemic herbaceous and perennial nickel-hyperaccumulating plant growing on Ni-enriched ultramafic soils in South Africa, is perceived as a promising species for phytoremediation and phytomining due to its large biomass production and high Ni content. Total concentrations of a number of elements in mature leaves, soil and related bedrock were obtained. The average Ni concentration in leaves was 18,000 μg·g -1 dry mass, whereas in soil and bedrock the total amount of Ni was 1,300 μg·g-1 and 1,500 μg·g-1, respectively. Exceptionally high average Ni concentrations (55;000 ± 15;000 μg·g-1; n = 6) were found in B. coddii leaves from Songimvelo Game Reserve, including the highest-ever reported concentration of Ni in leaves (76;100 μg·g-1 - maximum value in a single sample). Young plants grown in pots with ultramafic soil accumulated small quantities of Cd, Pb or Zn, but the concentrations of these elements increased after the addition of metal solutions to the soil. Excised shoots immersed in concentrated solutions of Cd, Ni, Pb or Zn accumulated large amounts of these metals in the leaves. © Polish Academy of Sciences, Cracow 2004.},
