0.001) postpartum. Participants in the audio group indicated less bladder neck descent (16.5 vs. 19.5, p = 0.020) at 6 weeks postpartum, better pelvic floor muscle strength (12.5% vs. 34.0%, p = 0.012; 4.2% vs. 18.0%, p = 0.030) and sexual function (22.2 vs. 17.3, p = 0.007) at 6 months postpartum. CONCLUSIONS The app-based audio guidance pelvic floor muscle training was more effective and much easier to comply for treatment of stress urinary incontinence in primiparas than the conventional home-based pelvic floor muscle training. BACKGROUND Previous studies suggest that psychoeducational interventions for pregnant and postpartum couples can improve perinatal mental health outcomes and promote couples' relationships. However, most studies conducted to date have focused only on maternal depression, with few studies addressing the needs of fathers, or the effects of paternal participation on the mental health/relationship of both partners. OBJECTIVES This study aimed to systematically examine the effects of perinatal couples' psychoeducation on parental mental health and their relationship. DESIGN A systematic review and meta-analysis were conducted. DATA SOURCES Six electronic databases were searched, including Embase, MEDLINE, Web of Science, the Cochrane Library, CINAHL, and PubMed. REVIEW METHODS The authors independently extracted data from journals written in English or Korean, published between January 2000 and August 2017. Randomized controlled trials (RCTs) that reported psycho-emotional symptoms and couples' relationship outcom paternal perception of the couple's relationship (SMD = 0.348; 95% CI 0.16 to 0.52); heterogeneity was I2 of 0% and p = .68. CONCLUSION This study was meaningful as it revealed evidence from published trials regarding the effectiveness of psychoeducational programs that target both pregnant women and their partners. Results indicate that psychoeducational interventions can reduce maternal postpartum depression and ameliorate paternal negative affect, as well as provide overall improvement in the couples' relationship satisfaction. However, further studies on physiological indicators and/or clinical symptoms of postpartum depression are needed to better understand the practical significance of psychoeducational intervention. This research was aimed at determining the effects of multi-walled carbon nanotubes (MWCNTs) on seed germination, seedling growth parameters and secondary metabolite (SM) production of Thymus daenensis in vitro. Seeds were aseptically cultured in Murashige and Skoog medium (MS) with various concentrations of MWCNTs (0, 125, 250, 500, 1000 and 2000 μg ml-1). Seed germination and morphological changes in seedlings were measured. The measurements were aimed at quantifying the total phenolic contents (TPC) and flavonoids (TFC), antioxidant activities and the activity of polyphenol oxidase (PPO), l-phenylalanine ammonia-lyase (PAL), dehydrogenase (DHA) and peroxidase enzyme (POD) of the seedling extract. Seedling biomass and seedling height grew significantly as the MWCNTs level increased. The biomass and height peaked at 250 μg ml-1 (0.41 ± 0.01 gr FW, 5.99 ± 0.55 cm) and then rapidly decreased to 0.040 ± 0.1 gr FW and 1.42 ± 0.24 cm in response to 1000 μg ml-1, 30 days after the treatment. Additionally, SM and the analyses of enzyme activity revealed that the highest amounts of TPC (6.70 ± 0.06 mg GAE g-1 DW), TFC (8.19 ± 0.01 mg QUE g-1 DW), antioxidant activities (73.88 ± 0.47%) and maximum PAL activity (1.25 ± 0.08 mM cm g-1 FW) were detected in plants grown on MS media fortified with 250 μg ml-1 MWCNTs. The results reveal that MWCNTs in low doses (250 μg ml-1) can encourage the production of biomass, elicit more SM from seedlings and enhance the biosynthesis of antioxidants. TEM images showed that MWCNTs could cross the plant cell wall and enter the cellular cytoplasm. Sulfidized nanoscale zerovalent iron (S-nZVI) is an Fe-based reactant widely studied for its potential use for groundwater remediation. S-nZVI reactivity has been widely investigated testing various contaminants in various water matrices, but studies on S-nZVI corrosion behaviour and reactivity upon exposure to complex groundwater chemistries are limited. Here, we show that anoxic aging of S-nZVI for 7 days in the absence and presence of key groundwater solutes (i.e., Cl-, SO42-, Mg2+, Ca2+, HCO3-, CO32-, NO3-, or HPO42-) impacts Fe0 corrosion extent, corrosion product and reduction rates with trichloroethene (TCE). White rust was the dominant corrosion product in ultrapure water and in SO42-, Cl-, Mg2+ or Ca2+ solutions; green rust and/or chukanovite formed in HCO3- and CO32- solutions; magnetite, formed in NO3- solutions and vivianite in HPO42- solutions. The aged S-nZVI materials expectedly showed lower reactivities with TCE compared to unaged S-nZVI, with reaction rates mainly controlled by ion concentration, Fe0 corrosion extent, type(s) of corrosion product, and solution pH. Comparison of these results to observations in two types of groundwaters, one from a carbonate-rich aquifer and one from a marine intruded aquifer, showed that S-nZVI corrosion products are likely controlled by the dominant GW solutes, while reactivity with TCE is generally lower than expected, due to the multitude of ion effects. Overall, these results highlight that S-nZVI corrosion behaviour in GW can be manifold, with varied impact on its reactivity. Thus, testing of S-nZVI stability and reactivity under expected field conditions is key to understand its longevity in remediation applications. Presence of heavy metals in the wastewater sludge has greatly hindered sludge land application. Bioleaching has been developed for heavy metal removal from sludge. The pH of the sludge is declined by microorganisms with S or FeS as energy source. Sludge considered to be used in land is mainly due to its fertilizer values as it contains nitrogen, phosphorus, and potassium. Therefore, it is important to understand how the bioleaching would impact on sludge characterization. In addition, pathogens are great threat to human health. The ability of pathogen elimination of bioleaching is highly concerned. In this review, the major heavy metals in the sludge are summarized. The change of nitrogen, phosphorus, and potassium after bioleaching is stated. this website The pathogen elimination due to bioleaching has been discussed. The work has provided an insight of research need in sludge bioleaching with the aim of residual sludge land application. Lanthanum-modified bentonite (LMB, commercially called Phoslock®) has been widely applied in freshwater systems to manage eutrophication. Little is known, however, about its behaviour and efficiency in binding filterable reactive phosphorus (FRP) in saline environments. We assessed if LMB would adsorb phosphate over a range of salinities (0-32 ppth) comparing the behaviour in seawater salts and equivalent concentrations of NaCl. Lanthanum release from the bentonite matrix was measured and the La species prevailing in saline environments were evaluated through chemical equilibrium modelling. We demonstrated that LMB was able to adsorb FRP in all the salinities tested. Filterable lanthanum (FLa) concentrations were similarly low (2000 times greater in equivalent NaCl salinities. Mineralogical analysis indicates that La present in the clay interlayer was (partially) replaced by Na/Ca/Mg present in the seawater and a possible secondary P-reactive phase was formed, such as kozoite (LaCO3OH) or lanthanite (La2(CO3)3·8H2O) that may be physically dissociated from the LMB. Geochemical modelling also indicates that most FLa dissociated from LMB would be precipitated as a carbonate complex. In light of the identification of reactive intermediate phases, further studies including ecotoxicologial assays are required to assess any deleterious effects from the application of LMB to saline waters. In this study, the effect of ball milling on pyrite (FeS2) promoting arsenic (As) removal by zero-valent iron (Fe0) was investigated. The influences of different mass ratios of ball-milled FeS2/Fe0, the dosage of ball-milled FeS2/Fe0 used and initial pH value were evaluated by batch experiments. The results showed that the ball-milled FeS2/Fe0 system had a higher total As removal efficiency than the mixed FeS2-Fe0 system, ball-milled FeS2 and ball-milled Fe0 systems in equal mass. Higher As removal efficiency in ball-milled FeS2/Fe0 system was primarily related to the accelerated corrosion of Fe0, which was supported by the determination of total Fe2+ release and electrochemical experiments. SEM-EDS and XPS characterizations revealed that there were iron sulfides (Fe(II)-S and Fe(III)-S) produced on the surface of Fe0 in ball-milled FeS2/Fe0, which could facilitate the electron transfer of Fe0 and enhanced the corrosion of it. BET test also indicated that ball-milled FeS2/Fe0 possessed a higher specific surface area than ball-milled Fe0. In addition, the results also showed the optimum mass ratio of FeS2 and Fe0 in ball-milled FeS2/Fe0 to remove As ([As(III)] = 2 mg/L) was 11, and the optimum dosage was 0.5 g/L, thereby indicating the optimal AsFe0 molar ratio was about 1168. And the removal rate of As by ball-milled FeS2/Fe0 was faster in acidic condition than that in alkaline condition. These findings suggest that Fe0-based arsenic removal efficiency can be enhanced by ball-milling with FeS2, making it more feasible for remediation of arsenic-polluted water. The application of chemical dispersants in marine oil spill remediation is comprehensively reported across the globe. But, the augmented toxicity and poor biodegradability of reported chemical dispersants have created necessity for their replacement with the bio-based green dispersants. Therefore, in the present study, we have synthesized five ionic liquids (ILs) namely 1-butyl-3-methylimidazolium lauroylsarcosinate, 1,1'-(1,4-butanediyl)bis(1-H-pyrrolidinium) dodecylbenzenesulfonate, tetrabutylammonium citrate, tetrabutylammonium polyphosphate and tetrabutylammonium ethoxylate oleyl ether glycolate, and formulated a water based ILs dispersant combining the synthesized ILs at specified compositions. The effectiveness of formulated ILs dispersant was found between 70.75% and 94.71% for the dispersion of various crude oils ranging from light to heavy. Further, the acute toxicity tests against zebra fish and grouper fish have revealed the practically non-toxic behaviour of formulated ILs dispersant with LC50 value greater than 100 ppm after 96 h. In addition, the formulated ILs dispersant has provided excellent biodegradability throughout the test period. Overall, the formulated new ILs dispersant is deemed to facilitate environmentally benign oil spill remediation and could effectively substitute the use of hazardous chemical dispersants in immediate future. The present studies interpret the speciation of uranyl (UO22+) with the most ubiquitous class of natural species named pyrazines in terms of stability, speciation and its identification, thermodynamics, spectral properties determined by a range of experimental techniques and further evidenced by theoretical insights. UO22+ forms ML and ML2 kind of species with a qualitative detection of ML3 species, while the ESI-MS identified the formation of all the complexes including ML3. Both the ligands act as bidentate chelators with a difference in ring size and coordinating atoms in the complex formed. The ML3 complexes involve the third ligand participation as monodentate via carboxylate only due to the restricted coordination number and space around the UO22+ ion to accommodate three ligand molecules in its primary coordination sphere. All the complexes are found to be endothermic and purely entropy driven formations. The complex formations showed redshift in the absorption spectra and the shift was further enhanced from ML to ML2 formation.
