Cadmium (Cd) is a well-known environmental pollutant and can damage fish. MicroRNAs (miRNAs) can involve in inflammation and immunosuppression. However, the mechanisms of miRNAs are still unclear in common carp (Cyprinus carpio L.) treated by Cd. In current study, 54 juvenile common carp were randomly divided into the control group and the Cd group (0.26 mg L-1 Cd) and were cultured for 30 days. The results revealed inflammatory damage in the spleens of common carp after Cd exposure using morphological construction. There were 23 differentially expressed miRNAs including 17 up-regulated differentially expressed miRNAs (miR-1-4-3p, miR-7-1-5p, miR-7-2-5p, miR-10-43-5p, miR-34-3-5p, miR-128-4-3p, miR-128-5-3p, miR-132-2-5p, miR-132-6-5p, miR-216-3-5p, miR-216-4-5p, miR-375-2-3p, miR-375-4-3p, miR-375-5-3p, miR-375-7-3p, miR-375-8-3p, and miR-724-5p) and 6 down-regulated differentially expressed miRNAs (miR-9-6-5p, miR-25-9-3p, miR-31-3-5p, miR-31-12-5p, miR-103-5-5p, and miR-122-1-3p). The 23 miRNAs regulated 2RNA-mRNA network analysis. Our study provided new insights into the toxicology of Cd exposure. Microplastics (MPs) have been gaining the attention of environmental researchers since the 1960s anecdotal reports of plastic entanglement and ingestion by marine creatures. Due to their increasing accretion in aquatic environments, as well as resistance towards degradation, marine litter research has focused on microplastics more recently. In the present study, a relatively new method of biodegradation was implemented for the biodegradation of three structurally different MPs i.e. polypropylene (PP), polyethylene (PE) and polyethylene terephthalate (PET). Periphytic biofilm was used for this purpose in various backgrounds of carbon sources (glucose, peptone, and glucose and peptone). Biodegradation of MPs was estimated in terms of weight loss. It was observed that the addition of glucose enhanced the biodegradation of MPs by periphyton biofilm for all MPs (from 9.52%-18.02%, 5.95%-14.02% and 13.24-19.72% for PP, PE and PET respectively) after 60 days compared to natural biofilm alone. To the contrary, peptone, and glucose and peptone together, were inhibitory. Biodegradation was further confirmed by morphological changes observed using SEM, FTIR spectra and GPC lent further support to the results whereby new peaks appeared along with reduction in old peaks and decrease in peak intensities. MiSeq sequencing shows that Deinococcus-thermus > Proteobacteria > Cyanobacteria are the dominant phyla in natural biofilms, and their relative abundances increase after the addition of glucose. However, the abundances shifted to Deinococcus-thermus > Cyanobacteria > Firmicutes > Bacteroidetes, when the biofilms were treated with either peptone alone, or with glucose and peptone together. Therefore, the change in biodegradation capability might also be due to the change in the microbial community structures after addition of the C-sources. These experiments provide an innovative approach towards effective biodegradation of MPs using a relatively new environment-friendly method. Algicidal behavior is a common interaction between marine microalgae and bacteria, especially in the dissipation phase of algal blooms. The marine bacterium Halobacillus sp. P1 was previously isolated and exhibits high algicidal activity against the diatom Skeletonema costatum. However, little is known about the mechanism underlying this algicidal process. Here, a tandem mass tag (TMT)-based proteomic approach was coupled with physiological analysis to investigate the cellular responses of S. costatum when treated with P1 culture supernatant. Among the 4582 proteins identified, 82 and 437 proteins were differentially expressed after treatment for 12 and 24 h, respectively. The proteomic results were in accordance with the results of verification by parallel reaction monitoring (PRM) assays. Proteins involved in reactive oxygen species scavenging, protein degradation and transport were upregulated, while proteins participating in nitrogen metabolism, protein translation, photosynthetic pigment biosynthesis and cell cycle regulation were significantly downregulated (p-value ≤0.05), corresponding to the increasing malondialdehyde content and the decreasing nitrogen, protein and chlorophyll a contents. A nutrient competitive relationship might exist between the bacterium P1 and S. costatum, and the inhibition of nitrogen metabolism by the P1 culture supernatant might be the key lethal factor that results in the dysfunction of S. costatum metabolism. Our study sheds light on the algicidal mechanism of P1 at the molecular level and provides new insights into algae-bacteria interactions. Addition of organic residues to soil is a current farming practice but it is not considered in the modelling studies for pesticide risk assessment at regulatory level despite its potential impact on the pesticide dynamics in soil. Thus, the objective of this work was to examine and to compare the ability of PRZM and MACRO pesticide fate models to simulate soil water content, and bromide (Br-, tracer), chlorotoluron and flufenacet concentrations in the soil profiles (0-100 cm) of one agricultural soil, unamended (control soil, S), amended with spent mushroom substrate (S + SMS) or amended with green compost (S + GC). Based on a two-year field-scale dataset, the models were first calibrated against measurements of water and solutes contents in the soil profiles (first year) and then tested without any further model calibration by comparison with the field observations of the second year. In general, the performance of MACRO to simulate the whole dataset in the three soil treatments was higher than that of PRZM.n PRZM and MACRO (such as the formation of herbicide-DOC mobile complexes). This work showed that models such as PRZM and MACRO are able to simulate the fate of pesticides in amended soils. However, before using these models as predictive tools in large amended soil conditions, and especially in the regulatory context, further modelling studies should focus on other pedoclimatic-pesticides-organic residues combinations, and on longer periods. It is documented that a few days or weeks before major Earthquakes (EQs) there are changes in animal behavior within distances up to 500 km from the seismic epicenter. At the same time Seismic Electric Signals (SES), geomagnetic and ionospheric perturbations, are detected within similar distances. SES consist of single unipolar pulses, and/or groups of such pulses called "SES activities" with an average frequency between successive pulses on the order of ~0.01 Hz and electric field intensity on the order of ~10-5-10-4 V/m (Frazer-Smith et al., 1990; Rikitake, 1998; Varotsos et al., 1993, 2011, 2019; Hayakawa et al., 2013; Grant et al., 2015). We show that the SES activities can be sensed by living organisms through the "Ion Forced-Oscillation Mechanism" for the action of Electromagnetic Fields (EMFs) on cells, according to which polarized EMFs can cause irregular gating of electro-sensitive ion channels on the cell membranes with consequent disruption of the cell electrochemical balance (Panagopoulos et al., 2000, 2002, 2015). This can be sensed by sensitive animals as discomfort in cases of weak and transient exposures, and may even lead to DNA damage and serious health implications in cases of intense exposure conditions (as in certain cases of man-made EMF exposures). Moreover, we show that the geomagnetic and ionospheric perturbations cannot be sensed through this mechanism. The same mechanism has explained meteoropathy, the sensing of upcoming thunderstorms by sensitive individuals, through the action of the EMFs of lightning discharges (Panagopoulos and Balmori, 2017). The present study shows that centuries-long anecdotal rumors of animals sensing intense upcoming EQs and displaying unusual behavior, lately documented by systematic studies, are now explained for the first time on the basis of the electromagnetic nature of all living organisms, and the electromagnetic signals emitted prior to EQs. INTRODUCTION Adolescent behavioural problems are a growing public health concern. The authors in this study investigated paternal and maternal reports of parenting attitudes and dimensions as predictors of adolescent behavioural problems in the Indian context. MATERIALS AND METHODS Using stratified sampling at the community level, 640 parents including 419 mothers and 221 fathers participated in the study. Tools included a socio-demographic pro-forma; Parental attitude inventory (PAI) to assess parenting attitudes, Parent Global Report of the Alabama Parenting Questionnaire (APQ) to assess current parenting dimensions, and the parent version of the Strengths and Difficulties Questionnaire (SDQ) to assess behavioural problems among adolescents. We examined the prevalence and predictors of total difficulties, externalizing and internalizing behavioural problems among adolescents from paternal and maternal reports. RESULTS Paternal and maternal reports of total difficulties (11.3 %, 13.6 %), externalizing (2.3 %, 1.9 %) and internalizing behaviours (8.6 %, 7.4 %) among adolescents are reported. Predictors of abnormal behaviours per paternal reports included lower social class and poor paternal control. Being a male adolescent increased the odds of total difficulties and externalizing problems. Favourable maternal attitude, good maternal warmth and control predicted the reduced likelihood of total difficulties and externalizing behaviours per maternal reports. Paternal control and maternal warmth and control were found to reduce the likelihood of internalizing behaviours among adolescents. CONCLUSION Maternal attitude, paternal control and maternal warmth and control dimensions emerged as significant predictors of total difficulties, externalizing and internalizing behavioural problems among adolescents. V.BACKGROUND Recovery from dissociative identity disorder (DID) is associated with the process of integration, which includes an increasing sense of self-cohesion and ownership over one's own emotions. Emotion perception is a construction based on interplay between stored knowledge (past experience), and incoming sensory inputs, suggesting changes in emotion perception might occur at different levels of integration - but this remains unexplored. Therefore, we examined the association between integration, psychiatric symptoms, and facial emotion perception. We hypothesized higher integration would be associated with fewer psychiatric symptoms, and differences in the perception of emotions. METHODS Participants were 82 respondents to a cross-sectional web-based study. All participants met self-report cutoff scores for posttraumatic stress disorder (PTSD) and DID using the PTSD Checklist for DSM-5 and Multiscale Dissociation Inventory, respectively. Participants completed a psychometrically-matched test of facial emotion perception for anger, fear, and happiness called the Belmont Emotion Sensitivity Test. Participants also completed the Beck Depression Inventory II, Childhood Trauma Questionnaire, and Integration Measure, a validated measure of self-cohesion. RESULTS Higher integration scores were associated with lower depression, PTSD, and autobiographical memory disturbance scores. Repeated-measures ANCOVA confirmed integration significantly interacted with emotion category on the facial emotion perception task. Specifically, higher integration scores were associated with greater accuracy to fearful and angry faces. CONCLUSIONS While acknowledging the limitations of a cross-sectional design, our results suggest that the process of integration is associated with fewer psychiatric symptoms, and more accurate facial emotion perception. This supports treatment guidelines regarding integration as a therapeutic goal for DID.
