To investigate these associations, we conducted a systematic search of studies assessing perinatal outcomes in mothers and/or neonates exposed to vaping during pregnancy compared to those in women without prenatal vaping exposure through MEDLINE, EMBASE, Scopus, Web of Science, Cochrane Library, PROSPERO, and Google Scholar until July 5, 2024. We performed inverse-variance random-effects meta-analyses for maternal and neonatal outcomes of 23 studies with a total of 924,376 participants with 7552 reporting vaping-only use during pregnancy. Prenatal vaping was associated with 53% higher odds of an adverse maternal outcome (OR: 1.53; 95% CI: 1.27 to 1.85; I<sup>2</sup> = 80%), particularly with decreased breastfeeding (OR: 0.53; 95% CI: 0.38 to 0.72; I<sup>2</sup> = 45%) and reduced prevalence of adequate prenatal care (OR: 0.69; 95% CI: 0.56 to 0.86; I<sup>2</sup> = 82%). Prenatal vaping was also associated with a similarly 53% higher odds of an adverse neonatal outcome (OR: 1.53; 95% CI: 1.34 to 1.76; I<sup>2</sup> = 45%), such as low birth weight (OR: 1.56; 95% CI: 1.28 to 1.93; I<sup>2</sup>: 15%), preterm birth (OR: 1.49; 955 CI: 1.27 to 1.76; I<sup>2</sup>: 0%), and small for gestational age (OR: 1.48; 955 CI: 1.16 to 1.89; I<sup>2</sup>: 70%). This is the first comprehensive systematic review and meta-analysis demonstrating vaping during pregnancy as a risk factor for increased odds of both maternal and neonatal outcomes and underscores the urgency to address awareness and regulations of vaping and its potential harms to both humans and the environment.<h3>Registration</h3>PROSPERO CRD42023446266.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"34 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2024-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142886888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet, their sustainable management can be hindered by the indiscriminate impacts of simultaneous exploitation of fish from multiple distinct biological populations over extended periods of time. The quantification of such impacts is greatly facilitated by recently developed molecular tools—including diagnostic single nucleotide polymorphism (SNP) panels for mixed-stock analysis (MSA)—that can accurately detect the population identity of individual fish. However, the biological relevance of such tools over longer periods of time remains unknown. Here, we demonstrate that diagnostic SNP panels designed for contemporary MSA in Atlantic herring have a millennium-long biological relevance and applicability. We assign the population identity of ancient Atlantic herring specimens—obtained through famously profitable historic fisheries—up to 1300 years old from eight archaeological sites across Europe. Analyzing contemporary and ancient whole-genome data, we obtain evidence for the long-term mixed-stock exploitation of Atlantic herring. Despite such mixed-stock exploitation, we exclusively identify autumn-spawning herring amongst these archaeological remains, indicative of a specific biological availability or cultural preference for certain herring ecotypes in the past. Moreover, our results show that herring demographic patterns were relatively stable until the dramatic disruptions and stock collapses during the 20th century. We find small but significant reductions in genetic diversity over time, indicating long-term evolutionary consequences from 20th-century stock declines. The long-term applicability of diagnostic SNP panels underscores their biological relevance and cost-effective application for the genetic monitoring of herring stocks and highlights the utility of ancient DNA to obtain insights in herring ecology and population dynamics.","PeriodicalId":175,"journal":{"name":"Global Change Biology","volume":"240 1","pages":""},"PeriodicalIF":11.6,"publicationDate":"2024-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142887235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated the adsorption and biodegradation of ofloxacin (OFL) and the spread of ARGs in aerobic biofilm systems under MNA and conventional aeration (CVA) conditions. Results showed that the MNA increased OFL removal by 17.27%–40.54% and decreased total ARG abundance by 36.37%–54.98%, compared with CVA. MNA-induced biofilm rough morphology, high zeta potential, and reduced extracellular polymeric substance (EPS) secretion enhanced OFL adsorption. High dissolved oxygen and temperature, induced by MNA-enriched aerobic bacteria and their carrying OFL-degrading genes, enhanced OFL biodegradation. MNA inhibited the enrichment of ARG host bacteria, which acquired ARGs possibly via horizontal gene transfer (HGT). Functional profiles involved in the HGT process, including reactive oxygen species production, membrane permeability, mobile genetic elements (MGEs), adenosine triphosphate synthesis, and EPS secretion, were down-regulated by MNA, inhibiting ARG spread. Partial least-squares path modeling revealed that MGEs might be the main factor inhibiting ARG spread. This study provides insights into the mechanisms by which MNA enhances antibiotic removal and inhibits ARG spread in aerobic biofilm systems.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"54 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2024-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142886890","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Microalgal bioremediation has emerged as a popular and promising solution to mitigate the risks. Nevertheless, the genetic underpinnings and engineering tactics involved in heavy metal bioremediation by microalgae remain inadequately elucidated. In this study, two mutants obtained from screening a <em>Chlamydomonas reinhardtii</em> (<em>C. reinhardtii</em>) mutant library were identified as insertional mutagenesis in the <em>AIDA</em> (<em>Cre12.g487450</em>) and <em>CYP720B1</em> (<em>Cre10.g426700</em>) genes. Interestingly, these two mutants exhibited decreased cell size and ciliary length but increased cell growth rates. Under Cu(II) stress, the <em>AIDA</em> and <em>CYP720B1</em> mutants presented dose-dependent tolerance to Cu(II), resulting in increased biomass and improved cellular morphology. Furthermore, the analysis for the antioxidant system suggested that increased Cu(II) tolerance was associated with a low-level response strategy to Cu(II) stress. Transmission electron microscopy images also revealed increased stress-related organelles (starch granules, acidocalcisomes, and plastoglobules) in these two mutants. Considering the excellent Cu(II) tolerance and biomass of these two mutants, our findings provide potential microalgal strains for further genetic modifications and performance mining to improve aquatic Cu(II) bioremediation through biomass enhancement.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"25 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2024-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142886928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study presents a comprehensive assessment of the RPV potential at the individual building level in the Netherlands, considering detailed building stock dynamics, renovation strategies, and heat transition scenarios. The results show that RPVs currently generate 3.86 TWh of electricity, with the potential to increase to 19.52 TWh. The total electricity demand of the residential building sector is about 27.26 TWh in 2020, which can increase significantly to 34.19-45.11 TWh by 2050, depending on heat pump penetration and renovation standards. RPVs alone can potentially meet about 43-57% of this electricity demand and save up to 11.32 Mt CO<sub>2</sub>-eq in 2050 (26% of current operational carbon emissions) if public grid electricity could be replaced by RPV electricity. However, the actual contribution of RPVs to the reduction/decarbonization of household electricity is subject to large uncertainties due to both the momentary and seasonal mismatch between RPV supply and electricity demand. Future research could increase the temporal resolution of our model to better explore the real potential of RPVs for targeted electrification and decarbonization in the building sector.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"1 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2024-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142887100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to elucidate the role of mitophagy in MC-LR-induced neurotoxicity both <em>in vitro</em> and <em>in vivo</em>. We found that administration of 10 μg/kg body weight (intraperitoneally) MC-LR impaired learning and memory abilities and induced neuronal damage and apoptosis in the CA1 region of the hippocampus in rats. Exposure to MC-LR (1 μM to 10 μM) resulted in cellular damage and apoptosis in PC-12 and HT22 cells. MC-LR induced mitophagy through the PINK1/Parkin pathway but hindered mitophagy progression by repressing Scd2 transcription in neurons. These inhibitory effects were reversed by Scd2 overexpression. Furthermore, MC-LR was found to repress Scd2 transcription by directly binding to type 1 insulin-like growth factor receptor (IGF-1R) and competitively inhibiting its activation by Insulin-like growth factor 1 (IGF-1). Overexpression of IGF-1R and administration of exogenous IGF-1 mitigated the MC-LR-induced inhibition of Scd2 and the associated mitophagy defects. These findings indicate that IGF-1R is the direct target of MC-LR in neurons.

Target screening (TS) is limited by the lack of reference standards, whereas non-target screening (NTS) is subject to complex and unreliable data processing. In this study, we reported the machine learning (ML)-powered pseudo-target screening (PTS) for primary identification of ECs with tetracyclines (TCs) serving as model. Based on mass spectrometry (MS) data collected from MassBank database, we performed data purification by removing interferential peaks through optimizing the threshold factor (<em>P</em>=1%), the parameter that reflected intensity of interferential peaks (<em>A</em>) in relative to that of maximum peak (<em>A</em><sub>max</sub>). Then, the well-trained XGBoost model was obtained for correct identification of TCs and Non-TCs with probability approaching 100% by feeding experimental MS data with integrated peak- and test-related features. We for the first time demonstrated the effectiveness of such feature integration strategy for improving accuracy, reliability and anti-interference ability offered by the ML models. The XGBoost model could also identify the TCs that were in the both presence and absence of model training set, suggesting potential generalizability for identifying the unregulated and unknown ECs. Compared with previously reported TS and NTS, our ML-powered PTS framework offered an efficient, simple and reliable alternative to identifying ECs in environmental samples without the need for prior knowledge. This study not only has important implications for dealing with accidental emergency of water pollution relevant to occurrence of ECs, but also represents paradigm shift to develop AI-powered algorithm frameworks for identifying more ECs beyond tested TCs herein.","PeriodicalId":443,"journal":{"name":"Water Research","volume":"25 1","pages":""},"PeriodicalIF":12.8,"publicationDate":"2024-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142884648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
