Objective: We aimed to investigate the prognostic value of neutrophil-to-lymphocyte ratio(NLR) and myeloidderived suppressor cells(MDSCs) in gastric cancer patients treated with second-line ramucirumab plus ***: A total of 116 patients with advanced or metastatic gastric cancer who receive ramucirumab plus paclitaxel were prospectively enrolled. Fresh blood samples were collected before and after treatment, and flow cytometry was performed to assess the proportions of monocytic(m MDSCs) and granulocytic MDSCs(g MDSCs).Results: Median age was 58 years and 71(61.2%) patients were male. A baseline NLR≥2.94 was associated with significantly poorer progression-free survival(PFS) and overall survival(OS) vs. an NLR<2.94(P=0.011 and P=0.002, respectively). In multivariate analysis, an NLR≥2.94 was independently associated with poorer PFS[hazard ratio(HR)=1.58;95% confidence interval(95% CI): 1.01-2.49, P=0.046] and OS(HR=1.77;95% CI:1.04-3.04, P=0.036). While m MDSC counts did not significantly change following two cycles of therapy(P=0.530),g MDSC counts decreased significantly after two treatment cycles(P=0.025) but tended to increase in patients with progressive disease after two treatment cycles(P=0.098). A progressive increase in g MDSC counts(≥44%) was associated with a significantly shorter PFS and OS vs. a g MDSC count increase <44%(P=0.001 and P=0.003,respectively).Conclusions: The baseline NLR may help guide clinical decisions during ramucirumab plus paclitaxel therapy for gastric cancer. Our g MDSC kinetics data warrant further clinical validation and mechanistic investigation.

Amyotrophic lateral sclerosis(ALS)is a progressive neurodegenerative disorder characterized by the degeneration of motor neurons in the brain and spinal cord,leading to muscle weakness,paralysis,and ultimately death(Cleveland and Rothstein,2001).Frontotemporal lobar degeneration(FTLD)is a neurodegenerative disease affecting the frontal and temporal lobes of the brain,leading to changes in behavior,personality,and language(Van Langenhove et al.,2012).Both ALS and FTLD are classified as proteinopathies in which abnormal protein aggregation and accumulation in neurons contribute to the disease *** in sarcoma(FUS)is a DNA/RNA-binding protein involved in various cellular processes,including transcriptional regulation,RNA splicing,and DNA *** in the FUS gene have been linked to familial ALS,highlighting the importance of FUS in the disease pathogenesis(Vance et al.,2009).In ALS and FTLD,aberrant post-translational modifications(PTMs)of FUS,such as phosphorylation,acetylation,and methylation,have been implicated in the promotion of FUS aggregation and neurotoxicity(Choi et al.,2023).Therefore,understanding the regulatory mechanisms of FUS PTMs is crucial for developing targeted therapies against these diseases.

Modeling the effects of constructed wetland on nonpoint source pollution control and reservoir water quality improvement

Journal of Environmental Sciences 2010年第6期22卷 834-839页

作者： Jonghwa Ham Chun G.Yoon hyung-Joong kim hyung-Chul kim Rural Research Institute of KRC Environmental Science Department Konkuk University

This article describes the integrated modeling approach for planning the size and the operation of constructed wetlands for maximizing retention of nonpoint source pollutant loads and reservoir water-quality improvement at a catchment scale. The experimental field-scale wetland systems （four sets, 0.88 ha each） have been in operation since 2002, where water depth was maintained at 30-50 cm and hydraulic loading rate was at 6.3-18.8 cm/day. The wetland system was found to be adequate for treating polluted stream water with stable removal efficiency even during the winter. The integrated modeling system （modified-BASINS） was applied to the Seokmoon estuarine reservoir watershed and calibrated with monitoring data from constructed wetland, stream, and reservoir. The calibrated integrated modeling system estimated that constructing wetlands on 0.5% （about 114 ha） of the watershed area at the mouth of reservoir could reduce 11.61% and 13.49% of total external nitrogen and phosphorus loads, respectively. It also might improve the nitrogen and phosphorus concentration of the reservoir by 9.69% and 16.48%, respectively. The study suggested that about 0.1%-1.0% of the watershed area should be allocated for constructed wetland to meet specified water-quality standards for the estuarine reservoir at the polder area where land use planning is relatively less complicated.
