Hexavalent chromium (Cr VI) is widely known as a potential hepatotoxic in humans and animals and its toxicity is associated with oxidative stress. So, an in vivo study was outlined to assess the protective and therapeutic role of Rosmarinus officinalis essential oil (rosemary; REO) against Cr VI-induced hepatotoxicity. link= https://www.selleckchem.com/products/pci-32765.html Male Wistar rats were assigned into five equal groups (1st group served as control; 2nd and 3rd groups received 0.5 ml/kg BW REO and 2 mg/kg BW Cr VI, respectively; 4th group pretreated with REO then injected with K2Cr2O7; and 5th group received Cr VI then treated with REO for 3 weeks). Results revealed that rats exposed to Cr VI showed a valuable changes in hematological parameters and an increase in oxidative stress markers (Protein carbonyl, TBARS, and H2O2) and a noteworthy decline in glutathione (GSH) content. Furthermore, a considerable decrease in enzymatic antioxidants (SOD, CAT, GPx, and GST), transaminases (AST and ALT), and alkaline phosphatase (ALP) activities, as well as total protein and albumin levels, was detected, while serum liver function biomarkers were increased significantly. In addition, the evaluation of histopathological and immunohistochemical PCNA expression showed significant variations in the liver that confirm the biochemical results. link2 Administration of REO pre- or post-chromium treatment restored the parameters cited above near to the normal values. Otherwise, individual intake with REO slumped lipid peroxidation and gotten better antioxidant status significantly. Conclusively, REO proved to be an effective antioxidant in modulating Cr VI-induced hepatotoxicity, especially in the pretreated rats.The acceptance of combined pre-composting and vermicomposting systems is increasing because of the advantage in rapidly stabilizing organic wastes and reducing emission of greenhouse gasses (GHG). However, GHG emission during the pre-composting phase is often neglected when evaluating the system. This study aimed to quantify GHG emission from a combined pre-composting and vermicomposting system and to investigate the effects of earthworms on GHG emission. https://www.selleckchem.com/products/pci-32765.html A combined system using Eisenia fetida was employed to stabilize maize stover and cow dung (mixing ratio 6040). The inoculating densities were 60 (T1), 120 (T2), and 180 (T3) earthworms per kilogram of substrate. A traditional composting system without earthworms was set as a control (T0). The results indicated that earthworms increased CO2 while decreased CH4 and N2O emissions compared to the control. Higher emission of CO2 suggested that the earthworms promoted the degradation of the substrates. Lower emission of CH4 and N2O showed the advantage of the combined system because CH4 and N2O possess extremely higher global warming potential than that of CO2. T2 is recommended for stabilizing maize stover and cow dung when making a tradeoff between stabilization rate and reduction of GHG. The percentages of GHG emission during pre-composting relative to total GHG emission in T1, T2, and T3 were 34%, 35%, and 30%, respectively. GHG emission is non-negligible when using a combined system, especially the emission of GHG during the pre-composting phase cannot be ignored.The natural abundance of Cr and Ni in serpentine soils is well-known, but the food safety of rice grown in these hazardous paddy soils is poorly understood. The study evaluated the bioaccumulation of chromium (Cr) and nickel (Ni) in rice (Oryza sativa) grown in serpentine-derived paddy soils in the Philippines. Surface soil (0-20 cm) samples were collected and characterized across three (i.e., Masinloc, Candelaria, and Sta. Cruz) paddy areas in Luzon Island, Philippines. At least 3 to 4 whole rice plants at mature stage were uprooted manually in each sampling point where the soil samples were collected. The total Cr and Ni concentrations in rice (i.e., roots, shoots, and grains) and soil, soil physicochemical properties, bioaccumulation factor (BAF), translocation factor (TF), and the hazard quotients (HQ) were determined. Results revealed that Cr and Ni in rice were accumulated mostly in the roots. Although paddy soils had elevated total Cr and Ni concentrations, the BAF and soil-to-root TF values for Cr and Ni were less then 1. In terms of human health risks, results further revealed low risk for both male and female Filipino adults as HQ values for Cr and Ni were less then 1. While it is safe to consume rice grown in the area in terms of Cr and Ni dietary intake, more studies are necessary to understand the dynamics and bioavailability of these heavy metals in other crops and drinking water from tube wells in these areas in order to provide a more holistic human health-based assessments and to ensure consumer safety in serpentine areas. In addition, a more reliable data on Cr and Ni speciation in serpentine soils and crops is critically important. Further studies are also needed to understand the contribution of bioavailable heavy metals in improving the soil health to achieve food safety.Airway hyperresponsiveness (AHR) is characterized by excessive bronchoconstriction in response to nonspecific stimuli, thereby leading to airway stenosis and increased airway resistance. AHR is recognized as a key characteristic of asthma and is associated with significant morbidity. At present, many studies on the molecular mechanisms of AHR have mainly focused on the imbalance in Th1/Th2 cell function and the abnormal contraction of airway smooth muscle cells. link3 However, the specific mechanisms of AHR remain unclear and need to be systematically elaborated. In addition, the effect of air pollution on the respiratory system has become a worldwide concern. To date, numerous studies have indicated that certain concentrations of fine particulate matter (PM2.5) can increase airway responsiveness and induce acute exacerbation of asthma. Of note, the concentration of PM2.5 does correlate with the degree of AHR. Numerous studies exploring the toxicity of PM2.5 have mainly focused on the inflammatory response, oxidative stress, genotoxicity, apoptosis, autophagy, and so on. However, there have been few reviews systematically elaborating the molecular mechanisms by which PM2.5 induces AHR. The present review separately sheds light on the underlying molecular mechanisms of AHR and PM2.5-induced AHR.Pollution is a global concern, increasing rapidly throughout marine and terrestrial ecosystems, and affecting many species. Urbanization enhances waste production, leading to the opening of landfills that constitute a spatially and temporally predictable food source for opportunistic species. Several species of gulls are known to exploit and breed in urban areas, taking advantage of accessible and diverse food resources. The exploitation of anthropogenic food subsidies at sea (e.g. link2 fishery discards), urban sites, and landfills leads to debris ingestion by gulls with potential negative effects. Here we characterize anthropogenic debris ingested by yellow-legged gulls (Larus michahellis) along Portugal, by analysing the content of pellets collected in (1) natural and urban breeding locations, and in (2) urban and landfill resting sites, to assess seasonal patterns in the ingestion of anthropogenic debris. We also relate diet with the presence of anthropogenic debris. Debris materials were found in 28.8% of pellets from breeding locations (natural and urban) and in 89.7% of pellets from resting sites (urban and landfill). Gulls from the most urbanized breeding location exhibited higher levels of ingested materials during the entire breeding cycle, however, gulls from a natural breeding site also ingested high levels of debris during the pre-breeding season. At resting sites, small seasonal differences were detected in the number and mass of debris items ingested, which were both higher during spring and summer. Gulls that typically fed on pelagic fish had significantly less sheet and fragment plastics in their pellets. The presence of certain debris categories in gull pellets was positively related to the presence of some prey items, suggesting that gulls may accidentally ingest debris while foraging at multiple habitats. The quantity of anthropogenic materials ingested by gulls from urban locations and landfills indicates a need for improved waste management.Although the Yangtze River Economic Belt (YREB) has been metaphorized as China's "arrow" to the world as it generates nearly half of the nation's gross domestic product, the region has also suffered immense environmental degradation during its development process. This paper uses environmental data from 2003 to 2013 of the YREB's nine provinces and two municipalities and investigates environmental remediation efficiency for the region. Results illustrate that (1) the efficiency of the YREB is very low as over the study period, only three provinces had mean environmental remediation values that could be classified as "effective," leaving the remaining six provinces and two municipalities as "ineffective"; (2) environmental efficiencies of the studied provinces and municipalities became increasingly polarized; (3) from 2003 to 2013, environmental efficiencies in the region have deteriorated; (4) the principal reason for environmental remediation ineffectiveness was due to a combination of redundant resource investments, excessive pollutant discharge, low industrial waste comprehensive utilization ratios, and non-municipal environmental remediation standards. To illuminate development pathways for the ineffective provinces and municipalities of the YREB, essential factors in the optimization of economic management investments are proposed.The efficient separation of low-concentration radionuclides by the eco-friendly adsorbent is a compelling requirement in the development of nuclear industry. Hence, a novel composite consisted of one-dimensional palygorskite (Pal) and three-dimensional pomelo peel (PP) is prepared by self-assembly approach (PP/Pal) and coupling agent approach (PP/KPal) for removing uranium (U(VI)) from aqueous solution. Moreover, the mass ratio (PP/Pal), adsorbent dosage, pH, contact time, temperature, and ionic strength are investigated. Two adsorption kinetic models and isotherm models are used to investigate the kinetic behaviors and adsorption capacity, respectively. link3 The maximum adsorption capacities were 370.5 mg·g-1 on PP/Pal and 357.3 mg·g-1 on PP/KPal at pH 6.0, contact time 150 min and 25 °C. Meanwhile, the composite can be easily separated from water via a simple filtering. Furthermore, thermodynamic parameters indicate that adsorption is an endothermic and spontaneous process. https://www.selleckchem.com/products/pci-32765.html And the surface complexation, ion exchange, and electrostatic attraction play a vital role. This work shows that the PP/Pal composite with high efficiency, low cost, and green has a further application in the treatment of wastewater containing U(VI).A native Indian catfish (Heteropneustes fossilis) and an Indian major carp (Cirrhinus cirrhosus) were treated with sodium dodecyl sulfate (SDS) to elucidate its consequences on antioxidant status and sex steroid synthesis. Fishes were exposed to 1/10th of LC50 of SDS for 30 days. Different enzymatic and non-enzymatic antioxidants, major sex steroids, steroidogenic enzymes, gonadosomatic index (GSI), and serum cortisol level were measured in both male and female fishes. Levels of enzymatic and non-enzymatic antioxidants altered significantly in both the fish species. Steroid hormones in both male and female fishes decreased significantly in the SDS-treated group. Profiles of steroidogenic enzymes (hydroxysteroid dehydrogenase; 3β-HSD and 17β-HSD) show significant decrease in the SDS treatment group in both carp and catfish than that of the control group irrespective of sexes. GSI also decreases significantly in the SDS-treated group when compared with the control group in spawning phase of carp and catfish irrespective of sexes.
