Abstract
OBJECTIVE To identify key pathological hub genes, micro RNAs (miRNAs), and circular RNAs (circRNAs) of osteoporosis (OP) and construct their ceRNA network in an effort to explore the potential biomarkers and drug targets for OP therapy. METHODS GSE7158, GSE201543, and GSE161361 microarray datasets were downloaded from Gene Expression Omnibus (GEO) database. Differentially expressed genes (DEGs) were identified by comparing OP patients with healthy controls and hub genes were screened by machine learning algorithms. Target miRNAs and circRNAs were predicted by FunRich and circbank, then ceRNA network were constructed by Cytoscape. Pathways affecting OP were identified by functional enrichment analysis. The hub genes were verified by receiver operating characteristic (ROC) curve and real time quantitative PCR (RT-qPCR). Potential drug molecules related to OP were predicted by DSigDB database and molecular docking was analyzed by autodock vina software. RESULTS A total of 179 DEGs were identified. By combining three machine learning algorithms, BAG2, MME, SLC14A1, and TRIM44 were identified as hub genes. Three OP-associated target miRNAs and 362 target circRNAs were predicted to establish ceRNA network. The ROC curves showed that these four hub genes had good diagnostic performance and their differential expression was statistically significant in OP animal model. Benzo[a]pyrene was predicted which could successfully bind to protein receptors related to the hub genes and it was served as the potential drug molecules. CONCLUSION An mRNA-miRNA-circRNA network is reported, which provides new ideas for exploring the pathogenesis of OP. Benzo[a]pyrene, as potential drug molecules for OP, may provide guidance for the clinical treatment.

Abstract
BACKGROUND: At present, dengue fever is a threat to society and causes rapid death. Aedes aegypti mosquito bites can transmit disease to the public. Environmental factors in society are the primary role that can transmit Dengue hemorrhagic fever (DHF).
AIM: Creating a survey system using a smartphone for early alertness to larva monitoring in the Darul Imarah sub-district, Aceh Besar district.
METHODS: This study used a descriptive quantitative approach which was carried out by the survey method. The research location is located in Darul Imarah District, Aceh Besar District. Primary data contain the value of the Container index (CI), House index (HI), and Breteau index (BI). This study’s population was all cadres of Juru Jentik (jumantik) in the area of Darul Imarah District, AcehBesar District. The sample in this study was taken from a cadre of larva monitoring officers (jumantik) in the district of Darul Imarah, Aceh Besar. The data collection stage includes data collection of DHF cases from the Puskesmas and data entry. Then proceed with taking the coordinates of the research location and entering the HI and CI, and News Index (BI) data. Data collection begins with data buffering, grouping, and kernel density to be processed into Geographics Instrument System (GIS)-based data. then Analyze descriptive data to describe Smartphone Link. Next, Analytical Analysis of GIS Research Instruments is carried out followed by a checklist of CI, HI, BI data.
RESULTS: The results of research on larvae monitoring in Darul Imarah sub-district, it is known that of the 120 houses that were inspected for larvae, 74 houses were cheerful 46 houses were negative for larvae. The number of containers inspected from 120 houses was 502, with the results that 309 houses were found to be larvae and 193 houses were not found. The HI value obtained was 62%, the CI value was 61%, the BI value was 103%, the larva-free number value obtained was 38.3%. Based on these results, it is known that the density figure level is at the larva density level, which is included in the high-density category. In 2018, there were 16 cases of DHF in Darul Imarah District; in 2019, it increased to 60 cases, and in 2020 to 13 cases. The results of buffer analysis in the zone 50 m from the dengue case sufferer’s house showed that mosquitoes originating from the house of the dengue case sufferers were a risk factor that resulted in the transmission of dengue.
CONCLUSION: From the survey results, it is known that the density figure is in the high larva density category. The smartphone method is better used for larva density surveys by cadres than manual. Regular larva monitoring will increase this alert system to anticipate cases.

Abstract
The greatest cause of preventable morbidity and mortality is smoking, and one of the often-underappreciated effects of smoking is profound bone loss. The existing clinical paradigm for smoking is that there is a low turnover osteoporosis. This review highlights findings from recent clinical trials and animal research demonstrating either support or conflict with the existing paradigm. Clinically, it is noted that markers of bone formation are often normal in smokers; these clinical findings conflict with well-conducted animal research demonstrating that carcinogens acting on the aryl hydrogen receptor can significantly reduce osteoblast formation and function. Regarding bone resorption, highlights from recent clinical studies suggest that bone remodeling is increased in smokers. Directly contradicting this enhanced osteoclastogenesis are several animal studies all demonstrating significant inhibition of osteoclast formation and function upon exposure to smoke carcinogens. Future research is needed to clarify whether smoking is truly a low bone remodeling osteoporosis, or an osteoclast-driven bone destruction, with inappropriately normal bone formation.

Abstract
Ecological risk and vulnerability maps can be used to improve the analysis of pollutant risks and communication to stakeholders. Often, such maps are made for one pollutant at the time. We used the results of wildlife vulnerability analysis, a novel trait-based risk assessment approach, to map overall vulnerability of habitats in Denmark to various metals and one insecticide. These maps were combined with maps of estimated soil concentrations for the same compounds divided by their Maximum Permissible Concentrations. This combination yielded relative risk maps that can be used to assess where the highest risk conditions to wildlife from these individual pollutants in Denmark occur (hot spot identification). In order to show how cumulative risk maps can be made, the maps of the individual pollutants were combined assuming different mechanisms of joint toxicity: no addition, concentration addition, antagonism and synergism. The study demonstrated that with an accurate set of geographical and ecological data one can use the results of vulnerability analysis to make relevant ecological risk maps that show hot spot areas for risks of single or cumulative risks from soil pollutants.

Abstract
Dioxins and PCBs are environmental pollutants, proven to be immunotoxic. In the period 1987-1991 a cohort of mother-baby pairs was initiated to detect abnormalities in relation to dioxin levels in the mother's milk. At birth and at follow-up at 8-12 years, immunological and hematological effects were seen, prompting us to perform a new follow-up during adolescence. In addition, we assessed the immunological and hematological parameters in relation to current levels of PBDEs and PCBs. In the Netherlands, the pre- and postnatal exposure to dioxins have been studied prospectively since 1987. Venapuncture was performed to assess hematological (Hemoglobin, thrombocytes, thrombopoietin) and immunological (leukocytes, leukocyte differentiation) parameters and the current serum levels of dioxin, dioxinlike (dl)-PCBs and PBDEs. A decrease in the number of polymorphic neutrophils was found in adolescents with higher dl-PCBs in their serum (p = 0.021). No relation with total leukocytes, thrombocytes, hemoglobin, or thrombopoietin levels was seen. Similarly, we found no relation between prenatal, nor current dioxin levels and the hematological and the immunological parameters determined. The SigmaPBDEs were negatively associated with the number of lymphocytes (p = 0.01) and positively associated with the hemoglobin concentration (p = 0.003). These effects on the innate immunity by current levels of dl-PCBs and on the adaptive immunity by PBDEs are disconcerting, especially as the dl-PCB (0.04-7.8 WHOTEQ pg/g lipid, mean: 2.2 WHOTEQ pg/g lipid) and SigmaPBDE levels (mean 14.0 ng/g lipid, including one outlier with a sum of 73.6 ng/g lipid) were not high.

Abstract
Managing risks to human health and the environment produced by endocrine-active chemicals (EAC) is dependent on sound principles of risk assessment and risk management, which need to be adapted to address the uncertainties in the state of the science of EAC. Quantifying EAC hazard identification, mechanisms of action, and dose-response curves is complicated by a range of chemical structure/toxicology classes, receptors and receptor subtypes, and nonlinear dose-response curves with low-dose effects. Advances in risk science including toxicogenomics and quantitative structure-activity relationships (QSAR) along with a return to the biological process of hormesis are proposed to complement existing risk assessment strategies, including that of the Endocrine Disruptor Screening and Testing Advisory Committee (EDSTAC 1998). EAC represents a policy issue that has captured the public's fears and concerns about environmental health. This overview describes the process of EAC risk assessment and risk management in the context of traditional risk management frameworks, with emphasis on the National Research Council Framework (1983), taking into consideration the strategies for EAC management in Canada, the United States, and the European Union.

Abstract
A risk map of the chemical/petrochemical industrial area of Tarragona (Catalonia, Spain) was designed following a two-stage procedure. The first step was the creation of a ranking system (Hazard Index) for a number of different inorganic and organic pollutants: heavy metals, polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), polychlorinated biphenyls (PCBs) and polychlorinated aromatic hydrocarbons (PAHs) by applying self-organizing maps (SOM) to persistence, bioaccumulation and toxicity properties of the chemicals. PCBs seemed to be the most hazardous compounds, while the light PAHs showed the minimum values. Subsequently, an Integral Risk Index was developed taking into account the Hazard Index and the concentrations of all pollutants in soil samples collected in the assessed area of Tarragona. Finally, a risk map was elaborated by representing the spatial distribution of the Integral Risk Index with a geographic information system (GIS). The results of the present study seem to indicate that the development of an integral risk map might be useful to help in making-decision processes concerning environmental pollutants.

Abstract
Apoptosis is an active form of cell death that plays a critical role in physiological and pathological conditions of multicellular organisms. These conditions include development, organogenesis, and elimination of infected, mutated, or damaged cells. Sipunculan cells may respond to changes in environmental exposure to oxidative stress by induction of apoptotic cell death. In coelomocytes of the sipunculan worm Themiste petricola, we evaluated morphological and biochemical changes that were induced by hydrogen peroxide (H2O2) and that could be compatible with an apoptotic-like phenotype. At an exposure of 100 mM H2O2, coelomocytes exhibited several morphological hallmarks of apoptosis such as chromatin condensation, nuclear segmentation, cell volume decrease, membrane blebbing, and formation of apoptotic bodies. Biochemical evidences of apoptotic-like cell death included exposure of phosphatidylserine (PS) in the outer leaflet of the plasma membrane and oligonucleosomal DNA fragmentation. In addition, exposure of coelomocytes to H2O2 induced a rapid massive loss of mitochondrial membrane potential and of the acidic pH of lysosomes. Overall, our results showed that, in sipunculan coelomocytes, H2O2 can induce changes compatible with an apoptotic-like phenotype. The finding of an oxidative-stress-induced apoptotic-like phenotype in a sipunculan worm may indicate that this kind of cell death process participates in regulation of cell number during physiological and pathological situations, including immune responses.
