Produced water is responsible for the largest contribution in terms of waste stream volume associated with the production of oil and gas Characterization of produced water is very crucial for the determination of its main components and constituents for optimal selection of the treatment method  https//wwwselleckchemcom/products/ferrostatin-1html  This review aims to review and critically discuss various treatment options that can be considered cost-efficient and environmentally friendly for the removal of different pollutants from produced water Great efforts and progresses were made in various treatment options, including batch adsorption processes, membrane filtration, advanced oxidation, biological systems, adsorption, coagulation, and combined processes Chemical precipitation, membrane filtration, and adsorption have high removal efficiencies that can reach more than 90 for different produced water components The most effective method among these methods is adsorption using different adsorbents media In this review, date-pits activated carbons, micronergy This is because of various dominant factors including the type of field, platform type, chemical composition, geological location, and chemical composition of the production chemicalsMacroalgal biosorption has shown promise for the removal of metal ions from wastewaters, whose presence can pose a threat to the aquatic environment There is a wealth of literature published on macroalgal biosorption, the common thread being that the biosorbent material was collected from the field, under undefined conditions These studies offer little insight into the impact of prior cultivation or biomass production practices upon the biosorbent material, its adsorptive physico-chemical properties and its subsequent capacity for metal removal The present study sought to investigate the influence of changes in macroalgal cultivation, specifically nutrient regime, upon biomass properties and the resultant adsorption performance The macroalga Cladophora parriaudii was cultivated under six different nutrient regimes; 21 and 121 NP molar ratios, with nitrogen supplied either as ammonium NH4+, nitrate NO3-, or urea CONH22 These nutrient regimes were designed to produce biomass of varying biochemical and cell surface profiles After cultivation, the biomass was rinsed, dried, biochemically analysed and then used for the removal of four individual metals from solution Metal removal varied considerably between treatments and across initial metal concentrations, with removal values of 46-85, 9-80, 8-71, and 49-94 achieved for Al, Cu, Mn, and Pb, respectively, with initial metal concentrations varying between 0 and 150 mg L-1 The observed variation in metal removal can only be attributed to differences in biochemistry and cell surface properties of the biosorbent induced by nutrient regime, as all other variables were constant This study demonstrates that prior cultivation conditions influence the biochemistry of a biosorbent material, namely macroalgae Cladophora parriaudii, which has an impact upon metal removal This aspect should be given due consideration for future biosorption research and when reviewing already published literatureOxygen is the electron acceptor in cathode chamber of microbial fuel cell-constructed wetland system MFC-CW The objective of the study lies in creating a "tidal flow" TF in cathode chamber via a siphon to enhance the oxygen diffusion, thus promoting the system performance A laboratory scale MFC-CW with a siphon driven TF recirculation was proposed and designed It allows the variable water level being created in four operational modes The results demonstrated the significance of the siphon which was reflected by the attractive wastewater treatment performance Compared with the tested four operational modes under the same hydraulic condition, the highest total nitrogen removal efficiency of 9632 and COD removal efficiency of 9237 were achieved, respectively, in 1st full siphon recirculation mode FSR and 2nd FSR operation mode Indeed, the water level variation range played an important role in pollutants removal performance Reduced water level variation of the TF in cathode chamber hindered excessive oxygen diffusion into MFC-CW and thus adversely affected the system performance It is clear that the siphon is a wiser input to bring about the better treatment performance, but it is believed that the enhanced microbial activities behind the oxygen promotion is the driven force to exhibiting a better performance in the MFC-CW systemThe SARS-CoV-2 virus has spread globally and has severely impacted public health and the economy Hand hygiene, social distancing, and the usage of personal protective equipment are considered the most vital tools in controlling the primary transmission of the virus Converging evidence indicated the presence of SARS-CoV-2 in wastewater and its persistence over several days, which may create secondary transmission of the virus via waterborne and wastewater pathways Although, researchers have started focusing on this mode of virus transmission, limited knowledge and societal unawareness of the transmission through wastewater may lead to significant increases in the number of positive cases To emphasize the severe issue of virus transmission through wastewater and create societal awareness, we present a state of the art critical review on transmission of SARS-CoV-2 in wastewater and the potential remedial strategies to effectively control the viral spread and safeguard society For low-income countries with h rate Though promising results have been shown by initial research for inactivation of SARS-CoV-2 in wastewater using physical, chemical and biological based treatment methods, there is a pressing need for extensive investigation of COVID-19 specific disinfectants with appropriate concentrations, their environmental implications, and regular monitoring of transmission Effective wastewater treatment methods with high virus removal capacity and low treatment costs should be selected to control the virus spread and safeguard society from this deadly virusVarious psychiatric disorders are treated with mindfulness-based interventions MBIs, although the efficacy of MBIs in patients with social anxiety disorder SAD is unclear In this meta-analysis, we investigated the efficacy of MBIs on SAD symptoms Systematic searches were performed in various databases, and 11 eligible randomized controlled trials RCTs and 5 single-arm trials were identified The between-groups analysis of the 11 RCTs showed that Hedges' g = 000, while the within-group analysis showed a large pre-post effect size g = 120MBIs were superior to the no-treatment comparator g = 089, equivalent to specific active treatment g = -019, and less effective than evidence-based treatment ie, cognitive behavioral therapies g = -029MBIs significantly alleviated depressive symptoms and improved mindfulness, quality of life, and self-compassion Meta-regression analysis showed a dose-response relationship between the alleviation of SAD symptoms and the duration of the MBIs β = 0659 Follow-up analysis showed that the effects of MBIs on SAD persisted for 12 months g = 0231 link2 An analysis of the 5 single-arm trials found that MBIs had a medium effect in alleviating SAD symptoms g = 048 Future research is needed regarding the design of large RCTs of MBIs on SAD patientsCognitive impairments are the hallmark of schizophrenia and prominent in the early episode stage However, the underlying pathological mechanisms of cognitive impairments are not fully understood This study aimed to investigate the abnormal functional connectivity FC of the cerebellar dentate nucleus DN and its correlation with cognitive impairments in patients with drug-naive and first-episode schizophrenia Resting-state functional magnetic resonance imaging data were acquired in 47 patients and 43 healthy controls Cognitive functions were assessed by number sequence span, verbal category fluency, digit-symbol coding tests The results showed that the patients had deficits in all three cognitive tests compared to the controls Furthermore, the increased FC of DN with the bilateral postcentral gyrus and decreased FC of DN with the right inferior temporal gyrus and regional cerebellum eg, Vermis 4-5 and Crus I were observed in the patient group compared to the control group Importantly, these abnormal DN FC significantly correlated with cognitive tests eg, number sequence span and digit-symbol coding and clinical symptoms eg, negative symptom in the patient group The results suggested that abnormal FC of DN with cortical and subcortical regions was associated with cognitive impairments and symptom severity and might be an underlying neural mechanism in schizophrenia
  Exposure to endocrine disrupting chemicals EDCs represents a critical public health threat link3 Several adverse health outcomes eg, cancers, metabolic and neurocognitive/neurodevelopmental disorders, infertility, immune diseases and allergies are associated with exposure to EDCs However, the regulatory tests that are currently employed in the EU to identify EDCs do not assess all of the endocrine pathways
 
  Our objective was to explore the literature, guidelines and databases to identify relevant and reliable test methods which could be used for prioritization and regulatory pre-validation of EDCs in missing and urgent key areas
 
  Abstracts of articles referenced in PubMed were automatically screened using an updated version of the AOP-helpFinder text mining approach Other available sources were manually explored Exclusion criteria computational methods, specific tests for estrogen receptors, tests under validation or already validated, methods accepted by regulatory bodies were applied according tegulatory pre-validation and, ultimately for the efficient prevention of EDC-related severe health outcomes This integrative approach highlights a successful and complementary strategy which combines computational and manual curation approachesIn this study, we constructed an innovative photo-electrocatalysis-assisted peroxymonosulfate PEC/PMS system to degrade pharmaceuticals and personal care products PPCPs A hollow-structured photoanode ie, PtCeO2MoS2 was specifically synthesized as a photoanode to activate PMS in the PEC system As proof of concept, the PtCeO2MoS2 photoanode exhibited superior degradation performance toward carbamazepine CBZ with PMS assistance Specifically, the kinetic constant of PEC/PMS k = 013202 min-1 could be enhanced about 874 times compared to that of the PEC system 000151 min-1 alone The PMS activation mechanism revealed that the synergistic effect between the hollow material and the change of surface valence states Ce3+ to Ce4+ and Mo4+ to Mo6+ contribute to enhancing the degradation efficiency of the visible-light-driven PEC/PMS process The scavenger testing and EPR showed that 1O2, O2•-, SO4•- and •OH play dominant roles in the SR-AOPs Furthermore, the applicability of PtCeO2MoS2 used in SR-AOPs was systematically investigated regarding of the reaction parameters and identification of intermediates and dominant radicals as well as the mineralization rate and stability The outcomes of this study can provide a new platform for environmental remediation
