As a result, the optimal CoNi-DH-S@CC (CoNi-DH prepared in Ni2SO4) serves as an advanced electrode to show high-rate capability (only 13% Cs decay after a 15-fold current elevation) and a superior specific capacity (Cs) of 929.4 C g-1, which remarkably exceeds those of CoNi-DH-N (823.1 C g-1, in Ni(NO3)2), CoNi-DH-Cl (798.4 C g-1, in NiCl2), CoNi-DH-C (803.8 C g-1, in Ni(CH3COO)2), and other similar metal hydroxides. Moreover, with this CoNi-DH-S electrode as the positive electrode, the as-prepared asymmetric supercapacitor (ASC) delivers an impressive capacity of 204.8 C g-1, a superior energy density of 42.5 Wh kg-1, and satisfactory cycle life (81.5% reservation after 7500 cycles). As a proof-of-concept application, a quasi-solid-state ASC is further successfully fabricated based on the CoNi-DH-S electrode to exhibit encouraging application potential.
Chronic rhinosinusitis with nasal polyposis (CRSwNP) remains a difficult-to-cure disease. The aim of this study was to determine the potential long-term predictors of revision sinus surgery for CRSwNP.
Prospectively gathered patients with bilateral CRSwNP who received primary endoscopic sinus surgery were enrolled. Clinical variables, including the preoperative Lund-Mackay score (LMS), were collected to clarify possible risk factors for revision surgery within a 5-year follow-up. The symptomatic burden was measured using a 10-cm visual analog scale (VAS) before and 1year after surgery. Further survival analysis was performed to present the revision-free survival in Kaplan-Meier plotting.
Eighty four qualified patients were identified and all of them experienced significant improvement in VAS after primary surgery. The 5-year revision rate was 19.05%, and the mean time of revision surgery was 25.31±17.11months postoperatively. Nasal allergy (OR=9.287; p=0.011) and LMS (OR=1.29; p=0.06) were found to be the independent risk factors for revision surgery. The discriminatory power of LMS for revision surgery was acceptable (AUC=0.79) with the best cutoff point located at LMS>13.5. Patients with both nasal allergy and LMS≧14 had only half of revision-free survival in comparison to overall survival (38.1% vs. 80.95%, p<0.001).
In patients with CRSwNP who have concurrent nasal allergy and higher preoperative LMS may indicate an advanced disease status and eventually be in a high risk of revision surgery after a long-term follow-up. An outcome-based staging system will be helpful in the future to improve the prognosis for CRSwNP.

The wastewater treatment plant (WWTP) is regarded as an important hotspot of ARGs in the urban environment, but the removal of ARGs through conventional treatment techniques has been proven not sufficient. In this study, ferrate (Fe(VI)) was applied for the first time to remove intracellular ARGs from the secondary effluent of the WWTP. The results showed that Fe(VI) treatment could effectively remove 15 ARGs covering eight different types as well as intI1, the most common integron important to ARGs horizontal transfer. The removal efficiencies of tested genes could reach 1.10-4.37 log at the Fe(VI) dosage of 10 mg-Fe/L, which is significantly higher than those achieved through traditional disinfection methods. Dibutyryl-cAMP purchase The DNA gel electrophoresis suggested that Fe(VI) could induce microbial DNA damage and consequently resulted in ARGs elimination. The presence of ARGs in settled residues indicated that coagulation initiated by Fe(VI) reduction products also contributed to ARGs removal from wastewater. In addition, the viability and relative abundances of potential ARGs hosts in the wastewater were decreased after Fe(VI) treatment. This study suggested a promising prospect for applying Fe(VI) to efficiently remove ARGs from wastewater, and consequently to control their proliferation and transfer in the environment.
This study was conducted to determine the presence, type, and rate of parasitic contamination in Iranian currencies.
This was a cross-sectional study.
Coins and banknotes of different denominations were randomly collected from sellers and markets in Tabriz, Northwest of Iran, for examining parasitic contamination.
Entamoeba coli and Giardia intestinalis were the most identified species of parasites in this study. Other parasites detected were Cryptosporidium parvum, Ascaris lumbricoides, Entamoeba histolytica, Fasciola hepatica, and Toxocara cati. A high rate of parasitic contamination was found in banknotes compared with coins, and a statistically significant association was found between parasitic contamination and the apparent condition of the currencies. The notes of lower denominations showed the highest contamination rates. The highest parasitic contamination was found in coins and banknotes obtained from public toilet services, butchers, and beggars.
The findings emphasize the role of circulating coins and banknotes in the risk of pathogenic parasite transmission.

However little is known regarding the underlying mechanisms of mitigation and especially how zeolite influences the microbial structuration. The aim of this study was to bring new contributions on the effect of zeolite on the microbial community arrangement under a low ammonia stress. Replicated batch experiments were conducted. The microbial population was characterised with 16S sequencing. Methanogenic pathways were identified with methane isotopic fractionation. In presence of ammonia, zeolite mitigated the decrease of biogas production rate. Zeolite induced the development of Izimaplasmatales order and preserved Peptococcaceae family members, known as propionate degraders. Moreover methane isotopic fractionation showed that hydrogenotrophic methanogenesis was maintained in presence of zeolite under ammonia low stress. Our results put forward the benefit of zeolite to improve the bacteria-archaea syntrophy needed for propionate degradation and methane production under a low ammonia stress.
