In oil absorption, the PMF offers an oil-absorption capacity of ≈70 g g-1 with only a 7% loss in capacity after 100 absorbing-squeezing cycles. Thus, systems combining solar energy with various waste foams are highly promising as durable, renewable, and portable systems for water purification, organic distillation, and oil absorption, especially in remote regions or emergency situations.Proton exchange membrane fuel cells (PEMFCs) are promising devices for clean power generation in fuel cell electric vehicles applications. The further request of high-efficiency and cost competitive technology make high-temperature proton exchange membranes utilizing phosphoric acid-doped polybenzimidazole be favored because they can work well up to 180 °C without extra humidifier. However, they face quick loss of phosphoric acid below 120 °C and resulting in the limits of commercialization. Herein UiO-66 derived carbon (porous carbon-ZrO2 ), comprising branched poly(4,4'-diphenylether-5,5'-bibenzimidazole) and polyacrylamide hydrogels self-assembly (BHC1-4) membranes for wide-temperature-range operation (80-160 °C) is presented. These two-phase membranes contained the hygroscopicity of polyacrylamide hydrogels improve the low-temperature proton conductivity, relatively enable the membrane to function at 80 °C. An excellent cell performance of BHC2 membrane with high peak power density of 265 and 656 mW cm-2 at both 80 and 160 °C can be achieved. Furthermore, this membrane exhibits high stability of frequency cold start-ups (from room temperature to 80 °C) and long-term cell test at 160 °C. The improvement of cell performance and stability of BHC2 membrane indicate a progress of breaking operated temperature limit in existing PEMFCs systems.Damage to the nervous system can result in loss of sensory and motor function, paralysis, or even death. To facilitate neural regeneration and functional recovery, researchers have employed biomaterials strategies to address both peripheral and central nervous system injuries. Injectable hydrogels that recapitulate native nerve extracellular matrix are especially promising for neural tissue engineering because they offer more flexibility for minimally invasive applications and provide a growth-permissive substrate for neural cell types. Here, we explore the development of injectable hydrogels derived from decellularized rat peripheral nerves (referred to as "injectable peripheral nerve [iPN] hydrogels"), which are processed using a newly developed sodium deoxycholate and DNase (SDD) decellularization method. We assess the gelation kinetics, mechanical properties, cell bioactivity, and drug release kinetics of the iPN hydrogels. The iPN hydrogels thermally gel when exposed to 37°C in under 20 min and have mechanical properties similar to neural tissue. The hydrogels demonstrate in vitro biocompatibility through support of Schwann cell viability and metabolic activity. Additionally, iPN hydrogels promote greater astrocyte spreading compared to collagen I hydrogels. Finally, the iPN is a promising delivery vehicle of drug-loaded microparticles for a combinatorial approach to neural injury therapies.
The present study aims to determine the association of trace elements and oxidative and DNA damage biomarkers with fall incidence among community-dwelling older adults.

This study is part of the Long-term Research Grant Scheme - Towards Useful Ageing cohort study in Malaysia. Of a total of 174 participants with complete trace elements and oxidative and DNA damage data during baseline, only 147 (84.5%) were successfully followed up after 18 months. Participants who experienced any fall events in the previous 18 months during the follow-up were categorized as fallers.

Thirty participants (20.4%) reported at least one fall in the previous 18 months. The mean concentrations of aluminium, lead and zinc were significantly higher (P < 0.05) in fallers than non-fallers. However, in comparison with the non-faller group, the percentage of DNA in tail (11.43 ± 4.10% vs. 13.22 ± 5.24%) and tail moment (1.19 ± 0.54 AU vs. 1.59 ± 0.78 AU) was significantly (P < 0.05) lower in the faller group. No significant difference in serum superoxide dismutase activities and malondialdehyde level was observed between non-fallers and fallers. Following multifactorial adjustments, higher aluminium (odds ratio [OR] 1.007; 95% confidence interval [CI] 1.002-1.011) and lead (OR 1.162; 95% CI 1.010-1.336) levels and lower tail moment scores (OR 0.313; 95% CI 0.138-0.709) appeared significant in the final hierarchical binary logistic regression model.

Higher levels of lead and aluminium were associated with increased risk of falls among community-dwelling older adults. Geriatr Gerontol Int 2021; •• ••-••.

However, the underlying mechanisms are poorly understood. Here, we develop a highly sensitive one-step enzymatic strategy for capture and profiling O-GlcNAcylated proteins in cells. Using this strategy, we discover that flap endonuclease 1 (FEN1), an essential enzyme in DNA synthesis, is a novel substrate for O-GlcNAcylation. FEN1 O-GlcNAcylation is dynamically regulated during the cell cycle. O-GlcNAcylation at the serine 352 of FEN1 disrupts its interaction with Proliferating Cell Nuclear Antigen (PCNA) at the replication foci, and leads to altered cell cycle, defects in DNA replication, accumulation of DNA damage, and enhanced sensitivity to DNA damage agents. Thus, our study provides a sensitive method for profiling O-GlcNAcylated proteins, and reveals an unknown mechanism of O-GlcNAcylation in regulating cell cycle progression and DNA damage response.The development of high-performance anode materials for potassium-based energy storage devices with long-term cyclability requires combined innovations from rational material design to electrolyte optimization. In this work, three-dimensional K + -pre-intercalated Ti 3 C 2 T x MXene with enlarged interlayer distance has been constructed for efficient electrochemical potassium-ion storage. We found that the optimized solvation structure of the concentrated ether-based electrolyte leads to the formation of a thin and inorganic-rich solid electrolyte interphase (SEI) on the K + -pre-intercalated Ti 3 C 2 T x electrode, which is beneficial for interfacial stability and reaction kinetics. As a proof of concept, 3D K + -Ti 3 C 2 T x //activated carbon (AC) potassium-ion hybrid capacitors (PIHCs) have been assembled and exhibited promising electrochemical performances. These results highlight the significant roles of both rational structure design and electrolyte optimization for highly reactive MXene-based anode materials in energy storage devices.Ultrasmall metal-organic frameworks (MOFs) may generate unique properties to expand the scope of applications. However, the synthesis is still a great challenge. Herein, we propose a strategy to synthesize ultrasmall MOFs by high gravity technology. With the aid of tremendous intensification of molecular mixing and mass transfer in high-gravity field, six typical MOFs were obtained instantaneously in a continuous way. These samples are monodispersed with sub-5 nm in size, smaller than the previously reported values and even close to the length of one crystal unit cell. As a proof-of-concept, catalytic activity for Knoevenagel reaction can be significantly enhanced using ultrasmall ZIF-8. Conversion time of benzaldehyde was decreased by 94 % or 75 % compared to those using conventional or hierarchically porous ZIF-8. More importantly, this approach is readily scalable with the highest space-time yield for nano-MOFs, which may promote the convenient synthesis and practical applications of ultrasmall MOFs in large-scale.Vaccination for COVID19 infection is in full swing all around the world and while the vaccines are considered overall safe, many cutaneous and extracutaneous adverse effects have been reported after their use. Local injection-site reactions are the commonest adverse effect described with the use of these vaccines. We describe a case of Sweet syndrome in an elderly female after the first dose of Oxford-AstraZeneca COVID-19 vaccine (AZD1222).Active center reconstruction is essential for searching high performance oxygen reduction reaction (ORR) electrocatalysts. Usually, the ORR activity stems from the special electronic environment of active sites through charge redistribution. In this work, we introduce "asymmetry" strategy to adjust the charge distribution of active centers by precisely designing conjugated polymer (CP) catalysts with different degrees of asymmetry. We synthesized asymmetric backbone CP ( asy-PB ) by modifying boron-nitrogen coordination bonds (B←N) and asymmetric sidechain CP ( asy-PB-A ) with different alkyl chain lengths. As a result, both CPs with backbone and sidechain asymmetry exhibit superior ORR performance to their symmetric counterparts ( sy-P and sy-PB ). Interestingly, asy-PB with greater asymmetry degree shows higher catalytic activity than asy-PB-A with relatively smaller asymmetry. Density functional theory calculations reveal that the increased dipole moment and non-uniform charge distribution caused by asymmetric structure endows the center carbon atom of bipyridine with efficient catalytic activity. These findings provide a mechanistic understanding of asymmetric ORR active structures and this approach gives a new strategy to design high-performance non-metal electrocatalysts.
Breast cancer beliefs are widely studied to improve preventative screening behaviors in women without cancer; however, limited research has examined breast cancer beliefs among breast cancer survivors. To fill this gap in research we investigated racial differences and the predicting role of influential factors (e.g., stage) in survivors' beliefs about their breast cancer.

This study is a secondary analysis of data from the Narrowing Gap in Adjuvant Therapy Study (2006-2011), where Black (N=210) and White women (N=149) were interviewed within 20 weeks following their breast cancer diagnosis and primary surgery in Washington DC and Detroit, MI. Outcomes of this analysis were perceived susceptibility to a breast cancer recurrence and perceived severity of breast cancer. Bivariate analyses were conducted to assess racial differences in sample characteristics, and on the study outcomes. Adjusted multiple regression models examined correlates between independent variables (e.g., sociodemographic/clinical) and commendations in the context of psycho-oncology and follow-up cancer care.
Recombinant coagulation factor VIII (FVIII) products are the standard of care for patients with haemophilia A. The development of modified FVIII products has provided benefit for patients but presented challenges for monitoring FVIII activity.

This single-centre study evaluated the Roche FVIII one-stage clotting assay (OSA) in measuring FVIII activity in plasma samples spiked with seven FVIII products at clinically relevant concentrations.

FVIII-deficient plasma samples were spiked with two batches of recombinant FVIII products (octocog alfa, moroctocog alfa, simoctocog alfa, efmoroctocog alfa, damoctocog alfa pegol, rurioctocog alfa pegol, lonoctocog alfa) at 1-120IU/dL FVIII activity, according to their labelled potency. Measurement was conducted on the cobas t 511/711 analysers using the Roche FVIII OSA and the Technoclone TECHNOCHROM FVIIIC chromogenic substrate assay (CSA).

Using the OSA, FVIII activity was close to labelled potency for most analysed FVIII products including a recombinant FVIII Fc fusion protein.
