Procambarus clarkii is an important freshwater cultured crayfish in China. With the gradual development of its aquaculture industry, research on white spot disease, which is harmful to healthy culture of P. clarkii, increases gradually. The prophenoloxidase (proPO) system is an important part of crayfish's innate immunity and plays a role in virus resistance. In this study, based on the early discovery of three SNP sites in the intron of proPO gene, the linkage disequilibrium and haplotype were analyzed for the SNPs, and it was found that there was a strong linkage disequilibrium relationship among them. Through the analysis on association between the haplotypes and genotype of each SNP site with the WSSV-resistant traits, the detection of the SNP_7081 genotype was considered as the most convenient and efficient way for WSSV-resistant group selection. Furtherly, the high-resolution melting curve (HRM), which is a rapid and economic genotyping method, was chosen to establish for SNP_7081 site genotyping. The 68 bp target fragment with 27.94% GC content was amplified and melting curve analysis were performed. However, the appearance of false negatives which led to unable automatically grouped although the melting curves of genotypes CC, C>T and T>C were obviously different, and could be treated as standard to manually genotype the samples with an accuracy rate of 97.61%. The low GC content which correlated with the Tm value, was confirmed as the reason for the false negatives by the assay about the recombinant plasmid PMD18-T-SNP_7081 constructed with 45.24% GC content. Eventually, the adaptor primers were used to increase the GC content of the target fragment, and a modified HRM method for genotyping SNP_7081 site that could group automatically was established, which could provide a new insight for the HRM method to genotype SNPs.Protein phosphorylation and dephosphorylation are the most common and important regulatory mechanisms in signal transduction, which play a vital role in immune defense response. Our previous study has found the level of tyrosine phosphorylation was significantly changed in the hemocytes of Fenneropenaeus chinensis upon white spot syndrome virus (WSSV) infection. In order to explore the relationship between protein phosphorylation and WSSV infection, the quantitative phosphoproteomics was employed to identify differential phosphorylated proteins in hemocytes of F. chinensis before and after WSSV infection, and elucidate the role of key differential phosphorylated proteins in WSSV infection process. The results showed that a total of 147 differential phosphorylated proteins were identified in the hemocytes, including 64 phosphorylated proteins and 83 dephosphorylated proteins, which were mostly enriched in pyruvate metabolism, TCA cycle, glycolysis, and ribosomal biosynthesis. Functional analysis of differentiaSV infection, which help to clarify the response characteristics and virus resistance mechanism of hemocytes in F. chinensis, and also facilitate further understanding of the interaction between WSSV and shrimp hemocytes.Chlorhexidine (CHX) is considered to be the gold standard for dental caries prevention and is widely applied in dental practice. However, the long-term application of CHX may result in CHX-resistance in oral pathogens. The aim of this study was to investigate whether long-term use of CHX causes resistance in Streptococcus mutans and to explore the possible associated mechanisms. Four different S. mutans strains were chosen for this study to exclude the specificity of strains. The four strains displayed an increase in minimum inhibitory concentration (MIC) after exposure to CHX for 10 passages. The features and cariogenicity of S. mutans CHX-resistant strains (SM-Cs) that were exposed to CHX for 10 passages with increased MIC did not differ significantly to the parental strains. The SM-Cs were more hydrophobic than the parental strains. The dltC and dltD genes were upregulated in SM-Cs. Relative expression of the BceA, BceR, and SMU.862 genes in SM-Cs was similar to or lower than that of the parental strains. The MIC value was significantly lower in dltC knockout mutants. These findings confirmed that continuous exposure to CHX could induce CHX-resistance in S. mutans. The increased cell surface hydrophobicity and upregulated expression of dlt operon were possible underlying mechanisms of CHX-resistance in S. mutans.The Infectious Diseases Society of America (IDSA) recommends numerous antibiotics for the treatment of urinary tract infections (UTIs) caused by extended-spectrum β-lactamase (ESBL)-producing bacteria. The purpose of this study was to evaluate clinical outcomes of oral step-down antibiotics compared with continued intravenous therapy in UTIs without bacteraemia. This multicentre, retrospective, cohort study was conducted in hospitalised patients with ESBL-producing UTIs between July 2016 and March 2020. The primary outcome was a composite all-cause clinical failure, defined as 30-day re-admission, 30-day hospital mortality or a change in oral antibiotics during hospitalisation. Secondary outcomes included individual primary outcome components, re-admission due to a recurrent UTI, change in antibiotic during hospitalisation, hospital length of stay (LOS), antibiotic costs and adverse events. The study included 153 patients. The primary outcome occurred in 28% of both groups (27/95 vs. 16/58; P = 0.91). The primary outcome components were similar re-admission (26% vs. 26%; P = 0.95); hospital mortality (2% vs. 2%; P = 1.0); and change in antibiotics (0% vs. 2%; P = 0.38). Mean hospital LOS and direct antibiotic costs were 8 ± 6 days vs. 5 ± 2 days (P less then 0.01) and US$278 ± 244 vs. US$180 ± 104 (P less then 0.01), respectively. Adverse events were similar, except diarrhoea (15% vs. 2%; P = 0.01). There was no difference in clinical failure, re-admission rate, re-admission due to a recurrent UTI, mortality rate or antibiotic change between groups. The switch group was associated with reduced hospital LOS and inpatient antibiotic costs.This research examines water, sanitation, and hygiene (WASH) accessibility and opportunity in Kibera and Mathare during the COVID-19 pandemic in 2021. Kibera and Mathare are two of the largest urban informal settlements in Nairobi (the capital city of Kenya) as well as Sub-Saharan Africa. Accessibility indicates how easily a person can reach WASH facilities from their home by walking. Opportunity represents how many WASH options a person has near their home. We utilize the data on water and toilet facilities collected by GroundTruth Initiative in partnership with Map Kibera Trust (local community partners) between February and April 2021 - amid the COVID-19 pandemic. By conducting quantitative geospatial analysis, we illustrate WASH accessibility and related issues that were not evident in previous studies (1) 77.4% of people living in Kibera have limited WASH facility accessibility or opportunity; (2) 60.6% of people living in Mathare have limited WASH facility accessibility or opportunity; (3) there is a clear geographic pattern in WASH facility accessibility and opportunity; and (4) overall accessibility and opportunity is better in Mathare than in Kibera. This study is one of the first studies to examine WASH accessibility and opportunity in urban informal settlements during the COVID-19 pandemic by utilizing the current data and quantitative geospatial methods. Based on the results, we discuss important public health policy implications for people living in urban informal settlements to improve their WASH facility accessibility and opportunity during the COVID-19 pandemic.The effects of phosphate mining on rhizosphere bacteria in surrounding vegetables and crops, including Lactuca sativa, Glycine max, and Triticum aestivum, are assessed in this study. As results, phosphate mining significantly increased the contents of some large elements, trace elements, and heavy metals in the surrounding agricultural soil, including phosphorus, magnesium, boron, cadmium, lead, arsenic, zinc, and chromium (P less then 0.05). The community richness and diversity of bacteria in rhizosphere of the three crops were significantly reduced by phosphate mining (P less then 0.05). Abundances of Sphingomonas and RB41 in the rhizosphere soil of phosphate mining area improved compared with the baseline in the non-phosphate mining area. check details Beta diversity analysis indicated that phosphate mining led to the differentiation of bacterial community structure in plant rhizospheres. Bacterial metabolic analysis indicated that different plant rhizosphere microbial flora developed various metabolic strategies in response to phosphate mining stress, including enriching unsaturated fatty acids, antibiological transport systems, cold shock proteins, etc. This study reveals the interaction between crops, rhizosphere bacteria, and soil pollutants. Select differentiated microbial strains suitable for specific plant rhizosphere environments are necessary for agricultural soil remediation. Additionally, the problem of destruction of agricultural soil and microecology caused by phosphate mining must be solved.The low carbon building design has become critical given the urgent need to reduce global carbon emissions. Reducing operational energy use through multi-objective optimizations used to be a common approach, but its validity is impaired by surging embodied impacts. Therefore, a life cycle optimization becomes necessary to improve the overall carbon performance of buildings. However, current research lacks an application of multi-objective optimizations to explore the energy use, carbon emission and cost considering both embodied and operational impacts. Impacts of confounding design factors and climate change on achieving low carbon designs are also not sufficiently revealed by existing studies. To address these gaps, this study (i) proposes a parametric design optimization method for low carbon buildings considering cost-effectiveness, (ii) explores the impacts of confounding factors on achieving low carbon designs and (iii) evaluates the impact of climate change on the life cycle performance of buildings with proper scenario assumptions. A case study is conducted to explore passive design parameters and integrated photovoltaic (PV) applications to reduce the energy use and carbon emissions in a cost-effective approach. The joint optimization of embodied and operational impacts can reduce the energy use, carbon emission and cost by 42%, 58% and 32%, respectively. Also, variation of confounding factors can lead to different optimized designs with carbon reduction difference up to 75%. The results also show that global warming will lead to higher energy use and carbon emissions in tropical regions within the near future, while stringent mitigation strategies aligned with RCP 2.6 can reverse the trend after two decades.In this paper, we develop a framework and metrics for estimating the impact of emission sources on regulatory compliance and human health for applications in air quality planning and life cycle impact assessment (LCIA). Our framework is based on a pollutant's characterization factor (CF) and three new metrics Available Regulatory Capacity for Incremental Emissions (ARCIE), Source CF Ratio, and Activity Health Impact (AHI) Ratio. ARCIE can be used to assess whether a receptor location has capacity to accommodate additional source emissions while complying with regulatory limits. We present CF as a midpoint indicator of health impacts per unit mass of emitted pollutant. Source CF Ratio enables comparison of potential new-source locations based on human health impacts. The AHI Ratio estimates the health impacts of a pollutant in relation to the utilization of the source for each unit of product or service. These metrics can be applied to any pollutant, energy source sector (e.g., agriculture, electricity), source type (point, line, area), and spatial modeling domain (nation, state, city, region).
