Effects of peripheral blood neutrophil/lymphocyte ratio levels and their changes on the prognosis of patients with early cervical cancer.

Although some studies have reported on the levels and clinical significance of peripheral blood neutrophil/lymphocyte ratio (NLR) in cervical cancer, the role of NLR levels and their changes preoperatively and postoperatively in early cervical cancer remain unclear. Our analyses explored the preoperative and postoperative NLR in 203 patients with stage I-IIA cervical cancer and evaluated the relationship between NLR changes, clinicopathological characteristics, and patient prognosis. The cut-off preoperative and postoperative NLR values were determined using receiver operating characteristic curve analysis.

Degradation of trichloroethylene by double dielectric barrier discharge (DDBD) plasma technology: Performance, product analysis and acute biotoxicity assessment.

Trichloroethylene is carcinogenic and poorly degraded by microorganisms in the environment. Advanced Oxidation Technology is considered to be an effective treatment technology for TCE degradation. In this study, a double dielectric barrier discharge (DDBD) reactor was established to decompose TCE.

Microbial community evolution and functional trade-offs of biofilm in odor treatment biofilters.

Biofilters inoculated with activated sludge are widely used for odor control in WWTP. In this process, biofilm community evolution plays an important role in the function of reactor and is closely related to reactor performance. However, the trade-offs in biofilm community and bioreactor function during the operation are still unclear.

Microbial community regulation and performance enhancement in gas biofilters by interrupting bacterial communication.

Background: Controlling excess biomass accumulation and clogging is important for maintaining the performance of gas biofilters and reducing energy consumption. Interruption of bacterial communication (quorum quenching) can modulate gene expression and alter biofilm properties. However, whether the problem of excess biomass accumulation in gas biofilters can be addressed by interrupting bacterial communication remains unknown.

Reduction of biofilm adhesion strength by adjusting the characteristics of biofilms through enzymatic quorum quenching.

Biofilm adhesion to the surface of a carrier plays an essential role during biofilm formation. Quorum quenching (QQ) has been shown to have great potential for delaying biofouling. However, little is known about whether QQ reduces the adhesion strength of biofilms during the formation process to inhibit biomass accumulation.

Emissions, measurement, and control of odor in livestock farms: A review.

Odor emissions from intensive livestock farms have attracted increased attention due to their adverse impacts on the environment and human health. Nevertheless, a systematic summary regarding the characteristics, sampling detection, and control technology for odor emissions from livestock farms is currently lacking. This paper compares the development of odor standards in different countries and summarizes the odor emission characteristics of livestock farms.

Improving Broadband White-Light Emission Performances of 2D Perovskites by Subtly Regulating Organic Cations.

Recently, 2D organic-inorganic hybrid lead halide perovskites have attracted intensive attention in solid-state luminescence fields such as single-component white-light emitters, and rational optimization of the photoluminescence (PL) performance through accurate structural-design strategies is still significant. Herein, by carefully choosing homologous aliphatic amines as templates, isotypical perovskites [DMEDA]PbCl (1, DMEDA=N,N-dimethylethylenediamine) and [DMPDA]PbCl (2, DMPDA=N,N-dimethyl-1,3-diaminopropane) having tunable and stable broadband bluish white emission properties were rationally designed. The subtle regulation of organic cations leads to a higher degree of distortion of the 2D [PbCl ] layers and enhanced photoluminescence quantum efficiencies (<1 % for 1 and 4.

Performance enhancement of a biofilter with pH buffering and filter bed supporting material in removal of chlorobenzene.

Acidic substances, which produced during chlorinated volatile organic compounds, will corrode the commonly used packing materials, and then affect the removal performance of biofiltration. In this study, three biofilters with different filter bed structure were established to treat gaseous chlorobenzene. CaCO and 3D matrix material was added in filter bed as pH buffering material and filter bed supporting material, respectively.

Gel-encapsulated microorganisms used as a strategy to rapidly recover biofilters after starvation interruption.

Biosystems used for volatile organic compound (VOC) control have slow re-acclimation after extended starvation. In this study, a gel-encapsuled microorganism biofilter (GEBF) for the treatment of VOCs was used for rapid recovery after starvation interruption. Another conventional perlite biofilter (BF) was used as a control.

The anti-tumour effect of Mel and its role in autophagy in human hepatocellular carcinoma cells.

Melittin (Mel), a major component of venom of honey bee (), has various biological effects. Recent researches have reported the anti-tumor activity of Mel in various human cancers, including hepatocellular carcinoma (HCC). In this study, we aimed to further discuss the role of Mel in HCC and investigate the correlation of autophagy with the effect of Mel in HCC cells.

Treatment of hydrophobic volatile organic compounds using two-liquid phase biofilters.

The traditional one-liquid phase biofilter (OLPB), with water as the selected liquid phase, demonstrated low performance to volatile hydrophobic organic compounds. In this study, a novel two-liquid phase biofilter (TLPB) using silicone oil and water was established to treat gaseous dichloromethane (DCM). A comprehensive investigation of removal performance, kinetic analysis, biomass accumulations, pressure drops, CO productions, and microbial communities of the two biofilters was compared.

Comparison of physical technologies for biomass control in biofilters treating gaseous toluene.

Unlabelled: Excessive accumulation of biomass within gas-phase biofilters often results in the deterioration of removal performance. Compared with chemical and biological technologies, physical technologies are more effective in removing biomass and inducing less inhibition of the biofilter performance. This study applied different physical technologies, namely, air sparging, mechanical mixing, and washing with water at various temperatures, to remove excess biomass in biofilters treating toluene.
