The present study serves as an example of how a multidimensional matrix population model can integrate effects across the life cycle, provide a linkage between endpoints observed in the individual and ecological risk to the population as a whole, and project outcomes for multiple generations.Polycystic ovarian syndrome is a major factor contributing to the increasing incidence of infertility around the world. The metabolic effects of prolonged exposure to PCOS have been well determined from previous studies and seem to be detrimental in the long run. Studies have shown a multitude of conditions like insulin resistance, obesity and cardiovascular disorders to be associated with PCOS. This makes PCOS a syndrome requiring utmost attention in terms of women's health and reproduction. Interleukin-6 is one of the many cytokines released by adipocytes from fat deposits in the body. This review focuses on the Interleukin 6 signaling pathway and the data available on inflammatory modulators due to its significance PCOS mediated inflammation. There is noteworthy evidence of elevated IL-6 concentration in PCOS subjects that has been discussed in detail. The regulation of IL-6 levels in the body is in turn, maintained by a close relation with other cytokines, especially by a key regulator, NF-κB. Being involved in a multitude of other pathological conditions like rheumatoid arthritis, cardiovascular disorders, asthma, colon cancer and many more, the role of IL-6 is also investigated in PCOS in search of a probable reason for underlying inflammatory condition. On summarizing the IL-6 signaling pathway and therapeutic exploitation of the same, we see that IL-6 targeted drugs may be an efficient way of treating PCOS associated inflammation.This study aim was to investigate the influence of black soldier fly larvae (BSFL) Hermetia illucens L. (Diptera Stratiomyidae) on pathogenic bacteria (PB) survival in the chicken manure (CM), pig manure (PM), cow manure (COM) and sewage sludge (SS) compost. Three kinds of manure [chicken (T2), pig (T4) and cow (T6)] and SS (T8) were inoculated with BSFL (1.27 ratio on fresh weight basis) and without BSFL (T1, T3, T5 and T7) was used as control and experiment lasted for 9 days. The results indicated that BSFL amendment 90-93% of PB abundances (RAs) was significantly mitigate in CM and COM (T2 and T6), and 86-88% in PM and SS compost. However, relatively greater abundance of PB was recorded in the T4 and T8 treatments. Most of the PB belong to Proteobacteria, Firmicutes, Actinobacteria and Bacteroidetes phylum and their community composition varied from phylum to species levels among the all treatments. The PB composition was significantly altered by BSFL amendment and also important role play to enhance in coompost with significantly less abundance of pathogenic bacteria.The microplastic contamination of seafood species is increasingly becoming a global concern due to its potential influence on food safety and human health. This study investigated the presence and seasonal variation of microplastics in a commercially important marine shrimp species, Fenneropenaeus indicus, from the coastal waters of Cochin, India. The soft tissues of 330 shrimps were examined over a period of 12 months, from March 2018 to February 2019. A total of 128 microplastics were detected, of which 83% were fibres. An average (mean ± SD) of 0.39 ± 0.6 microplastics/shrimp (0.04 ± 0.07 microplastics/g wet weight) was obtained from the shrimps sampled. Microplastic contamination was significantly higher in July-August (Monsoon season) compared with other months. This study reports microplastic contamination in F. indicus for the first time. Results also suggest that consumption of peeled but undeveined or whole dried white shrimps can be one of the ways of the human uptake of microplastics, especially during the monsoon season.In addition to the anthropogenic sources for elevated concentrations of phosphorus (P) in groundwater systems, the importance of geogenic enrichment of P warrants attention. To assess factors controlling the sources and enrichment processes of P in Quaternary aquifers, 355 groundwater samples were collected in the Jianghan Plain of central Yangtze River Basin. In the phreatic aquifer, the total dissolved phosphorus (TDP) concentrations range from below detection limit (BDL) to 2.56 mg/L, with 6.25% of samples exceeding 1 mg/L; in the confined aquifer, TDP concentrations range from BDL to 4.31 mg/L, with 22.18% of samples exceeding 1 mg/L. Factor analysis and correlation were used to determine major factors controlling P enrichment in the groundwater. Elevated levels of P in the confined aquifer are related to reductive dissolution of P-rich Fe(III)-(hydr)oxides (FeOOH) as well as organic phosphorus (OP) mineralization. The SEDEX sequential extraction procedure was applied to core samples from two boreholes with high and low P levels in groundwater, respectively, to characterize phosphorus speciation in aquifer sediments. Bioavailable P, particularly exchangeable P, in sediments with high P groundwater are significantly higher than those with low P groundwater. see more The content of Fe-bound P is higher than that of residual organic P (Res-OP) in sediments from both boreholes, indicating the greater contribution of reductive dissolution of P-rich FeOOH to geogenic P enrichment in groundwater than OP mineralization. Using the Redfield ratio, groundwater samples collected from the confined aquifer can be divided into three groups, with 65% of the samples falling into the group closely related to reduction of FeOOH. The present research provides new insights into the enrichment of geogenic P in groundwater systems, which are not only applicable in the Jianghan Plain, but also to other similar alluvial aquifers in floodplains and delta regions worldwide.As the largest petrochemical industrialized city in northwestern China since the 1950s, Lanzhou has been well-known for its heavy surface ozone pollution. Given abundant emission sources of ozone precursors and the favorable environmental conditions for O3 formation, this study performed extensive atmospheric chemistry modeling investigations subject to 11 emission control scenarios. These scenarios increased and decreased emission levels of total volatile organic compound (TVOC) and nitrogen oxides (NOx), the two surface ozone (O3) precursor gases, to examine the relationships between O3 and NOx and TVOC. The modeling investigation was carried out for the summer of 2016 in the downtown and petrochemical industrial suburb in the city of Lanzhou. The results revealed that surface O3 in the downtown area of Lanzhou was controlled by VOCs and in the petrochemical-industrialized western suburb by NOx. Higher ozone levels were simulated in the west suburb of the city as compared with the downtown area, agreeing with measured data.
