METHODS： The carcinoembryonic antigen （CEA） mRNA levels in peritoneal washes from 65 cases of gastric cancer were detected by real-time RT-PCR. Peritoneal lavage cytology （PLC） was applied simultaneously to detection of free cancer cells. Negative controls included peritoneal washes from 5 cases of benign gastric disease and blood samples from 5 adult healthy volunteers. RESULTS： There was no CEA mRNA in peritoneal washes from benign gastric disease patients and in blood of adult healthy volunteers. The positive percentage of free cancer cells detected by real-time RT-PCR was 47.7% and only 22.3% by PLC. The positive rate of CEA mRNA was significantly related with serosa invasion between peritoneal metastasis and stage of gastric cancer. CONCLUSION： Real-time RT-PCR is a sensitive and rapid method for the detection of free cancer cells in peritoneal washes. The presence of free cancer cells in peritoneal washes is related to the Pathologic stage of gastric cancer.展开更多

Sodium bicarbonate mouth wash was recently shown to increase patients’ compliance. However, the cost implication of this strategy was never explored. Aim: This study is designed to explore the compounding of sodium bicarbonate 2% mouth wash from sodium bicarbonate powder USP and commercially procured intravenous solution, and to determine the estimated cost implication for patients using this strategy. Materials and Methods: Sodium bicarbonate 2% were compounded using commercially procured sterile intravenous 8.4% solution and powder USP, diluted and dissolved in sterile water for irrigation respectively. The estimated cost savings between the 2 methods were compared to each other as well as to savings from when used in preventing or in adjuvant therapy for chemotherapy induced mucositis. Ethical approval not required by UVA Institutional Review Board. Study conducted according to the International Standards of Good Practice. Result: We came up with a new recipe, sodium bicarbonate 2% mouth wash using commercially procured sterile liquid formulation. Due to shortage, we compounded with sodium bicarbonate powder USP. Using USP 795 regulation, we assigned 14 days beyond use date with refrigeration to these formulations. These formulations resulted in estimated cost savings of $3597.52 and $3686.56 respectively if patients were to be treated for chemotherapy induced mucositis for 21 days. When compared to commercially procured sterile liquid formulation, the use of powder USP, will lead to additional estimated 60 to 66.67% savings for patients. Conclusion: By using sodium bicarbonate powder or solution to compound a 2% mouth wash, we came up with a cheap product that could be used by patients in the moment in the hospital. We were also able to suggest ways that an estimated cost savings for patients undergoing cancer treatment that use this product can be computed.展开更多

The World Health Organization (WHO) has set a target for each United Nations member state to reach by 2030. Each member state is required to reach by 2022, 2025 and 2030 at least 60%, 80% and 100%, respectively of basic level of service of the five elements which are water, sanitation, hygiene, waste management and environmental cleaning. Methods: This study aimed to evaluate and document the current state of basic water, sanitation, and hygiene services in all lower-level health care facilities in the Dar es Salaam region of Tanzania as of July 2022. A cross-sectional study was conducted in 99 public dispensaries in the Dar es Salaam region’s five councils: Ubungo, Kigamboni, Kinondoni and Temeke Municipalities, and Ilala City. The interviewee form and observational checklists were both digitalized using the Kobo tool software. The respondents were health care facility in-charges or nurse in-charges. Data were downloaded, validated, and imported to Stata version 15 for analysis. Results: The basic WASH level per JMP is far below the target in 2022. Each member state by 2022 is required to reach at least 60% of the basic level of service of each element. We found a low coverage of basic WASH in the 99 dispensaries included in this study. The basic WASH coverage was met in only 10 (10.1%) of the dispensaries, while the remaining 89 (89.9%) dispensaries fall on limited WASH services. Conclusion: This study revealed lower coverage of basic WASH services in dispensaries. An urgent need is required to improve the status of WASH in all the dispensaries and facilitate the provision of quality health care services, patient safety and reduce health care associated infections.展开更多

Washing is vital for denim and other casual garments for bringing some interesting washed-down effects. Unwashed condition does not exhibit customer’s desired look, but after washing, the same garment becomes prominent in improved appearance, softness, comfort, light and dark shade, and patchy look that creates customer’s absolute satisfaction. Garment washing process increases the appeal with a lucrative outlook brought about by mechanical or chemical treatments in dry or wet conditions. This study gives an indication of different types of washing processes and the change of physical and chemical properties due to application of wet and dry washing processes as an imparting desired effect on garments. The aim of the project is to find out the changes that occur in physical properties of denim when it is subjected to stone enzyme wash on 12-ounce, 10-ounce and 8-ounce denim pants. Three different shades, namely dark shade, medium shade and light wash, were taken into consideration. Different behaviors and properties of the garments were found in the physical properties of the samples.展开更多

When compared to commercially procured sterile liquid formulation, the use of powder USP, will lead to additional estimated 60 to 66.67% savings for patients. Conclusion: By using sodium bicarbonate powder or solution to compound a 2% mouth wash, we came up with a cheap product that could be used by patients in the moment in the hospital. We were also able to suggest ways that an estimated cost savings for patients undergoing cancer treatment that use this product can be computed.

文摘Herein,a new method was developed for efficient and lasting fluorescent whitening cotton fabric by synthesizing and using a vinyl-containing fluorescent whitening agent to covalently grafting onto fiber surfaces with the assistance of electron beam irradiation.The results from FT-IR spectroscopic,X-ray photoelectron spectroscopic,and energy dispersive spectrometric analyses showed that the fluorescent whitening agent was successfully anchored on cotton fiber via radiation-induced grafting copolymerization.The optimized whiteness value at 110.81(that of raw cotton fabric,74.50)was achieved using just 0.3 wt% fluorescent whitening agent.Notably,the whiteness value of the treated cotton fabric remained 110+even after 100 equivalent home-washing cycles,substantiating its excellent washing durability.Skin stimulation experiments on rabbits showed that the primary stimulation index of all experimental groups was 0 and no abnormal clinical symptoms were found in all tested rabbits,demonstrating the outstanding skin safety.Furthermore,energy generated by irradiation grafting technology was much lower than that of traditional processes and water consumption greatly reduced.Even the effluent from this process completely met the discharge standard of industrial wastewater without any treatment.This study explores a new method for textile finishing via electron beam irradiation,providing a green and sustainable perspective for the textile industry.

文摘The nine typical Shanghai soils are usually silty clay or clay,which appears inconsistent with their low clay content in the relevant publications.The literature review shows that the documented clay content of Shanghai soils ranges from 0%to 30.8%by weight.This inconsistency may stem from two factors:(1)the Shanghai soil classification system relies solely on the plasticity index for soil naming;and(2)the conventional steel sieving method cannot separate the clay from the fine soils(clay and silt mixtures).This paper aims to accurately determine the clay content in Shanghai soils.It uses nylon cloth sieves with apertures ranging from 0.063 mm to 0.0008 mm and completely separates the clay particles from the fine soils.The nine typical Shanghai soils are tested and sieved into distinct subgroups of clay,silt,sand,and gravel particles.Results demonstrate clay content ranges from 18.99%to 79.33%,substantially higher than literature values and consistent with their names of either silty clay or clay.Macro,micro,and scanning electron microscope(SEM)images reveal effective separation of clay,silt,sand,and gravel particles.The clay exhibits cohesive properties,while the silt,sand,and gravel comprise clean,non-cohesive individual particles.The clay and silt fractions are confirmed to be within their respective sieving limits by SEM-based particle size measurements.Additionally,Atterberg limits testing highlights the high plasticity of the clay particles and the non-plastic nature of the silt particles.

文摘A growing global demand exists to formulate plans to lessen the greenhouse gas emissions produced by agricultural activities.The purpose of this study was to uncovered the changes in soil CO_(2)fluxes under varying scenarios including nitrogen fertilization rates,irrigation rates,and air temperatures in the Hetao Irrigation District(HID)over the 38-year period.DAYCENT model was used to predict carbon dioxide(CO_(2))fluxes from cultivated soils in the HID,Inner Mongolia from^(2)023 to 2060(the year of achieving the"carbon neutrality"goal)in this study.Results showed that mean soil CO_(2)fluxes in the sunflower field[1035.13 g/(m^(2).yr)]were significantly lower than those in the maize field[1405.54 g/(m^(2).yr)].An increase in nitrogen fertilization rate led to a significant escalation in soil CO_(2)fluxes.Moreover,elevating irrigation rates for washing salts by irrigation(WSBI)diminished soil CO_(2)fluxes in the sunflower field while amplifying them in the maize field.A rise in air temperature resulted in an increase in soil CO_(2)fluxes from the maize field,with annual increases observed,but a reduction in soil CO_(2)fluxes from the sunflower field.The sunflower fields in the HID have a more substantial advantage than the corn fields in mitigating soil CO_(2)emissions.

文摘Biogas production from Sargassum muticum,an invasive seaweed species to Europe,is hampered by low methane(CH_(4))yields during anaerobic digestion(AD),but causes are unclear.This research is the first to demonstrate the impact of extensive freshwater washing of spring-and summer-harvested S.muticum on the CH_(4)production rates and the biochemical methane potential(BMP).The findings reveal that the rate profile of CH_(4)production is affected by extensively washing the seaweed and is dependent on seasonality.Spring-harvested S.muticum had higher initial CH_(4)production rates compared to summer-harvested S.muticum.For spring-harvested S.muticum,the initial rate of CH_(4)production was lowered by extensive washing.In contrast,extensively washed summer-harvested S.muticum had a higher degradation rate and CH_(4)production rate relative to its non-extensively washed counterpart.The highest CH_(4)potentials accumulated by the treated and non-treated S.muticum are,however,statistically similar and not influenced by seasonality or extensive washing(p>0.05).Potential causes for differences in the rate of CH_(4)production between summer-and spring-harvested S.muticum are discussed.The differences in CH_(4)production from treated summer-and spring-harvested S.muticum acts as a stepping stone to understanding the causes for low CH_(4)yields,which could allow for further enhancements in CH_(4)production from S.muticum.

文摘The coupling of washing with adsorption process can be adopted for the treatment of soils contaminated with heavy metals pollution.However,the complex environment of soil and the competitive behavior of leaching chemicals considerably restrain adsorption capacity of adsorbent material during washing process,which demands a higher resistance of the adsorbents to interference.In this study,we synthesized strongly magnetic,high specific surface area(573.49 m^(2)/g)UiO66 composites(i.e.,UiO66-Fe_(3)O_(4))using hydrothermal process.The UiO66-Fe_(3)O_(4) was applied as an adsorbent during the ethylene diamine tetraacetic acid(EDTA)-assisted washing process of contaminated soil.The incorporation of UiO66-Fe_(3)O_(4)results in rapid heavy metal removal and recovery from the soil under low concentrations of washing agent(0.001 mol/L)with reduced residual heavy metal mobility of soil after remediation.Furthermore,UiO66-Fe_(3)O_(4)can quickly recollect by an external magnet,which offers a simple and inexpensive recovery method for heavy metals from contaminated soil.Overall,UiO66-Fe_(3)O_(4)configuration with EDTA-assisted washing process showed opportunities for heavy metals contaminated sites.

文摘Greenwashing behaviors(GWBs)in green finance products(GFPs)by enterprises seriously hinder the realization of environmental protection goals.However,methods for effectively regulating GWBs in GFPs are unclear.This study constructed a tripartite evolutionary game model to analyze the formation and governance mechanisms of GWBs in GFPs among regulatory authorities,enterprises,and investors.Subsequently,the stability equilibrium strategy and key factors influencing the system equilibrium were discussed.Several interesting conclusions were drawn.First,we demonstrated that an interdependence mechanism exists among three game agents who mutually influence each other.The larger the probability of regulatory authorities choosing active supervision and investors adopting feedback,the more enterprises are willing to carry out green projects.Second,three corresponding governance modes for GWBs were put forward following the developmental stages of GFPs.Among these,the collaboration mode is the most effective in incentivizing enterprises to implement green projects.Third,based on sensitivity simulations,the initial willingness of the tripartite stakeholders,investor feedback cost,investor compensation,the penalty for greenwashing enterprises,and the reputational benefit of enterprises are critical factors that influence evolutionary results.Finally,targeted countermeasures were provided for regulatory authorities to prevent enterprises from engaging in GWBs.

文摘Amidst the global energy and environmental crisis,the quest for efficient solar energy utilization intensifies.Perovskite solar cells,with efficiencies over 26%and cost-effective production,are at the forefront of research.Yet,their stability remains a barrier to industrial application.This study introduces innovative strategies to enhance the stability of inverted perovskite solar cells.By bulk and surface passivation,defect density is reduced,followed by a"passivation cleaning"using Apacl amino acid salt and isopropyl alcohol to refine film surface quality.Employing X-ray diffraction(XRD),scanning electron microscope(SEM),and atomic force microscopy(AFM),we confirmed that this process effectively neutralizes surface defects and curbs non-radiative recombination,achieving 22.6%efficiency for perovskite solar cells with the composition Cs_(0.15)FA_(0.85)PbI_(3).Crucially,the stability of treated cells in long-term tests has been markedly enhanced,laying groundwork for industrial viability.
文摘Background: Improving Water, Sanitation and Hygiene in health care settings is a critical prerequisite for achieving national health goals and Sustainable Development Goals (SDGs). The World Health Organization (WHO) has set a target for each United Nations member state to reach by 2030. Each member state is required to reach by 2022, 2025 and 2030 at least 60%, 80% and 100%, respectively of basic level of service of the five elements which are water, sanitation, hygiene, waste management and environmental cleaning. Methods: This study aimed to evaluate and document the current state of basic water, sanitation, and hygiene services in all lower-level health care facilities in the Dar es Salaam region of Tanzania as of July 2022. A cross-sectional study was conducted in 99 public dispensaries in the Dar es Salaam region’s five councils: Ubungo, Kigamboni, Kinondoni and Temeke Municipalities, and Ilala City. The interviewee form and observational checklists were both digitalized using the Kobo tool software. The respondents were health care facility in-charges or nurse in-charges. Data were downloaded, validated, and imported to Stata version 15 for analysis. Results: The basic WASH level per JMP is far below the target in 2022. Each member state by 2022 is required to reach at least 60% of the basic level of service of each element. We found a low coverage of basic WASH in the 99 dispensaries included in this study. The basic WASH coverage was met in only 10 (10.1%) of the dispensaries, while the remaining 89 (89.9%) dispensaries fall on limited WASH services. Conclusion: This study revealed lower coverage of basic WASH services in dispensaries. An urgent need is required to improve the status of WASH in all the dispensaries and facilitate the provision of quality health care services, patient safety and reduce health care associated infections.
文摘Garment washing is a significant area of the apparel industry. Washing is vital for denim and other casual garments for bringing some interesting washed-down effects. Unwashed condition does not exhibit customer’s desired look, but after washing, the same garment becomes prominent in improved appearance, softness, comfort, light and dark shade, and patchy look that creates customer’s absolute satisfaction. Garment washing process increases the appeal with a lucrative outlook brought about by mechanical or chemical treatments in dry or wet conditions. This study gives an indication of different types of washing processes and the change of physical and chemical properties due to application of wet and dry washing processes as an imparting desired effect on garments. The aim of the project is to find out the changes that occur in physical properties of denim when it is subjected to stone enzyme wash on 12-ounce, 10-ounce and 8-ounce denim pants. Three different shades, namely dark shade, medium shade and light wash, were taken into consideration. Different behaviors and properties of the garments were found in the physical properties of the samples.
