Persulfate may be electrochemically activated into sulfate radicals (SO4•-) or hydroxyl radicals (•OH) by accepting electrons on cathode. Although electro-activated persulfate has displayed good performance in oxidation of organic pollutants in wastewater, both yield and availability of radicals are still limited because the electrostatic repulsion resists the contact between persulfate anions and cathode. In this study, a flow-through cathode (FTC) with well-ordered micro-channels was fabricated via carbonization of wood. The solution containing persulfate ions flowed through these micro-channels and then activation of persulfate was confined and performed in the micro-channels, which enhanced remarkably the contact between persulfate ions and cathode. Under the residence time of 10 min and other optimized conditions, the decomposition rate of persulfate in FTC displayed 3.78 folds of enhancement compared with that on a flow-by cathode (FBC). EPR signal of •OH produced in FTC was also higher distinctly than that on FBC. The average removal rates of phenol and TOC in FTC were 97.9 % and 39.6 %, respectively, which were 2.61 times and 2.57 times as much as that on FBC. Cycling experiments indicated that this FTC had good stability. Therefore, activating persulfate in FTC is an efficient strategy to enhance the yield and availability of radicals.The highly hydrophobic surfaces make microplastics a potential carrier of organic pollutants in the marine environment. In order to explore the toxic effects of polybrominated diphenyl ethers (BDE-47) combined with microplastics on marine organisms, we exposed the marine mussel Mytilus coruscus to micro-PS combined with BDE-47 for 21 days to determine the immune defense, oxidative stress and energy metabolism of the mussels. The results showed that the clearance rate (CR) of mussels exposed to single micro-PS, single BDE-47 or both was lower than control group. this website In general, compared to single BDE-47 exposure, the combination of micro-PS and BDE-47 significantly increased respiration rate (RR), activities of acid phosphatase (ACP) and alkaline phosphatase (ALP), reactive oxygen species (ROS) production and malondialdehyde (MDA) concentrations, but significantly decreased lactate dehydrogenase (LDH) activity and the relative expression of heat shock protein (Hsp70 and 90). Overall, combined stress has more adverse effects on defense performance and energy metabolism in mussels and micro-PS seem to exacerbate the toxicological effects of BDE-47. As microplastics pollution may deteriorate in the future, the health of mussels may be threatened in organically polluted environment, which eventually change the stability of the structure and function of intertidal ecosystem.Purpose of the study Quality of life represents the principal outcome of health interventions for the oldest old. However, little is known about the determinants of quality of life in this population stratum. We evaluated the association between health-related quality of life (HRQoL) and handgrip strength in a cohort of 331 participants aged 90+ with a living in the Mugello area (Tuscany, Italy). Design and methods HRQoL was assessed using the Medical Outcomes Study Short Form 12 (SF12), considering the Physical Composite Score (PCS) and the Mental Composite Score (MCS) of the SF-12. Muscle strength was tested by hand grip dynamometry. Results The median MCS was 46.9, while the median PCS was 43.0. According to logistic regression, muscle strength was associated with increased probability of better PCS (OR = 1.05; 95 % CI = 1.01-1.10, P = .042), and better MCS (OR = 1.05; 95 % CI = 1.01-1.10, P = .036), after adjusting. Implication Muscle strength is associated with both physical and mental HRQoL among nonagenarians. Further studies are needed to explore the subsystems involved in this association, and whether improving muscle performance might improve global mental and physical quality of life in the most advanced age.Background In the present study, we assessed the relationship between serum alkaline phosphatase (ALP) levels and cognitive function changes in acute ischaemic stroke patients. Methods We retrospectively collected the demographic data and clinical information from the medical records of patients after the onset of ischaemic stroke. We used the Chinese version of the Mini-Mental State Examination to assess cognitive function. Mixed linear and logistic regression models adjusted for several factors were used to explore the relationship between ALP and cognitive impairment. Results A total of 1019 patients were included in the analysis, including 523 poststroke patients with cognitive impairment (PSCI) and 496 patients with non-PSCI. The incidence of poststroke cognitive impairment was 51.3 %. The serum ALP level in the PSCI group was significantly higher than that in the non-PSCI group (86.5 ± 18.9 U/L vs 68.6 ± 15.5 U/L, P less then 0.001). The mixed linear model fully adjusted for all variables indicated that the ALP level was positively associated with cognitive impairment (based on the Mini-mental State Examination score) decline, with changes from -0.54 to -0.16 per unit increase in ALP. The logistic regression revealed that the odds of cognitive impairment increased by 42 % when the ALP concentration increased by one U/L (odds ratio (OR) = 1.42, 95 %CI 1.17-3.09, P = 0.012). The spline regression model further confirmed the dose-response relationships between ALP levels and three-month cognitive impairment (P for nonlinear trend = 0.012). Conclusion The present study revealed that relatively high serum ALP levels at baseline might be an independent risk factor for cognitive impairment in patients with acute ischaemic stroke.Background and purpose Mild Cognitive Impairment (MCI) is associated with a greater risk of dementia for older adults. However, systematic reviews have shown that some physical exercise (PE) seems to improve MCI symptoms and signs. Those reviews and meta-analysis could not explain what possible moderator influenced their results. This meta-analysis aims to identify the effect of PE over older people's cognition with MCI and explore sources of heterogeneity. Methods Databases were searched from inception January 2020 for randomized clinical trials that evaluated the effects of PE over cognition of older persons with MCI. Random effect meta-analyses were performed for each cognitive outcome. Subgroup analyses and meta-regressions models explored the potential sources of heterogeneity. Results A total of 2077 participants (mean age = 71.8 years) from 27 studies were included. PE improves global cognitive function (SMD = 0.348 [95 % CI 0.166 to 0.529]; p = 0.0001), executive function (SMD = 0.213 [95 % CI 0.026 to 0.
