The inherent resistance to numerous antimicrobial agents contributes to the opportunistic character of this pathogen exhaustive monitoring of this pathogen is considered of critical importance to public health organizations. The reliable identification method able to distinguish genetic close Pseudomonas species is needed, because these organisms are difficult to differentiate by phenotypic or biochemical methods. The purpose of the present study was to design species-specific primers in order to identify and detect four Pseudomonas species which are frequently detected from the human oral cavities, and to investigate the distribution of these organisms in the living environment using a multiplex PCR. Methods: Polymerase chain reaction (PCR) primers were designed based on partial sequences of the rpoD gene of four Pseudomonas species. Swab samples were collected from fifty washstands, and the distribution of Pseudomonas species was investigated using a conventional PCR at genus level and a multiplex PCR at species level. Results: Multiplex PCR method developed in this study was able to distinguish four Pseudomonas species clearly. The genus Pseudomonas was detected from all samples (100%), whereas P. putida, P, aeruginosa, P. stutzeri and P. fluorescens were detected at 44%, 8%, 4% and 2% in fifty swab samples, respectively. Conclusion: Our developed one-step multiplex PCR method is accurate, specific, cost-effective, time-saving, and works without requiring DNA extraction. It was indicated that washstands were the uninhabitable environment for P. putida, P, aeruginosa, P. stutzeri and P. fluorescens.展开更多

Just like other remaining historical districts in Asia, those of Vietnam have been going through rapid urbanization and transformation. The rapid urbanization impacts on traditional living environment. This paper examines the impacts of rapid urbanization to traditional living environment and community linkage, illustrating a case study of the Gia Hoi area of the historic old district in the city of Hue in Central Vietnam. To identify the impacts, a comparative analysis is conducted between neighbors along a main street which were more impacted by urbanization and those along a small alley which were less impacted. Through the analysis of field and questionnaire surveys, it found out that socioeconomic conditions, in particular, community linkage of households along main street and small ally varied significantly. It argues that in historical district, social capital is not well-spread, but rather concentrated along small allies, and small allies play an important role for sustainable community.展开更多

Twenty-eight Sprague-Dawley rats were divided into control group （CG） and cerebral ischemia group, and the latter was further divided into subgroups of different housing conditions： standard environment （SE） subgroup, individual living environment （IE） subgroup, and enriched environment （EE） subgroup. Focal cerebral ischemia was induced by the middle cerebral artery occlusion （MCAO）. Beam walking test was used to quantify the changes of overall motor function. Cerebral infarction and cerebral metabolism were studied by in vivo magnetic resonance imaging and 1H-magnetic resonance spectra, respectively. Neuron necrosis and apoptosis were detected by hematoxylin-eosin and TUNEL staining methods, respectively. The results showed that performance on the beam-walk test was improved in EE subgroup when compared to SE subgroup and IE subgroup. Cerebral infarct volume in IE subgroup was significantly larger than that in SE subgroup （P〈0.05） and EE subgroup （P〈0.05） on day 14 after MCAO. NAA/Cr and Cho/Cr ratios were lower in MCAO groups under different housing conditions as compared to those in CG （P〈0.05）. NAA/Cr ratio was lower in IE subgroup （P〈0.05） and higher in EE subgroup （P〈0.05） than that in SE subgroup. NAA/ Cr ratio in EE was significantly higher than that in IE subgroup （P〈0.05）. Cho/Cr ratio was decreased in MCAO groups as compared to that in CG （P〈0.05）. A significant decrease in normal neurons in cerebral cortex was observed in MCAO groups as compared to CG （P〈0.05）. The amount of normal neurons was less in IE subgroup （P〈0.05）, and more in EE subgroup （P〈0.05） than that in SE subgroup after MCAO. The amotmt of normal neurons in EE subgroup was significantly more than that in IE subgroup after MCAO （P〈0.05）. The ratio of TUNEL-positive neurons in EE was significantly lower than that in SE subgroup （P〈0.05） and IE subgroup （P〈0.05）. Correlation analysis showed that the beam walking test was negatively correlated with NAA/Cr ratio （P〈0.05）. Cerebral infarct volume was negatively correlated with both NAA/Cr ratio （P〈0.01） and Cho/Cr ratio （P〈0.01）. The amount of normal cortical neurons was positively correlated with both NAA/Cr ratio （P〈0.0I） and Cho/Cr ratio （P〈0.05）. The TUNEL-positive neurons showed a negative correlation with both NAA/Cr ratio （P〈0.01） and Cho/Cr ratio （P〈0.01）. This study goes further to show that EE may improve neurological functional deficit and cerebral metabolism, decrease cerebral infarct volume, neuron necrosis and apoptosis, while IE may aggravate brain damage after MCAO.展开更多

文摘The evolution of the human living environment on the Tibetan Plateau(TP)and its influence on human activities is a major scientific issue of multidisciplinary interest.Based on published research on past environmental changes on the TP,we synthesize changes in landscape and other environmental components,including temperature,moisture,vegetation,and aeolian activity,on the glacial-interglacial and the Holocene suborbital timescales.This synthesis elucidates the processes,patterns,and mechanisms of environmental changes on the TP,on multiple timescales.We also explore the possible impacts of environmental changes on prehistoric human activities by combining chronological data from archaeological sites since the Paleolithic with the latest advances in archaeology,genetics,linguistics,and archaeobotany.Our findings indicate the following:(1)On a glacialinterglacial timescale,the environmental evolution of the TP exhibits a high spatiotemporal consistency,characterized by cold and dry conditions with sparse vegetation during glacial periods,and warm and humid conditions with flourishing vegetation during interglacial periods.(2)On the Holocene suborbital timescale,summer temperatures on the TP generally show a Holocene thermal maximum.However,reconstructions of mean annual temperature changes vary,likely due to factors including seasonal biases and regional differences in mean annual temperature proxies.In terms of moisture,the northern TP(especially the northeastern TP),which is influenced by both the summer monsoon and the westerly circulation,shows increased moisture since the early Holocene,in contrast to decreasing moisture in the southern monsoon-dominated parts.This constitutes a northsouth dipolar pattern of Holocene moisture changes.Furthermore,a series of abrupt climate events occurred on the TP during the Holocene,while there were pronounced regional differences in the environmental response to North Atlantic cooling events.Regarding terrestrial ecosystems,pollen assemblages reveal that vegetation succession on the TP generally responded to summer monsoon changes,with forest vegetation retreating and steppe/meadow vegetation expanding during the Holocene.Records of aeolian activity and paleosol development indicate that the northeastern TP experienced the most intensive aeolian activity in the early Holocene,while paleosol development was the most active during the middle-late Holocene.However,the spatiotemporal patterns of aeolian activity on the southern TP remain unclear.(3)On the glacial-interglacial timescale,prehistoric humans tended to spread from adjacent areas onto the TP during the relatively warm and biologically rich interglacials,while the harsh living environment during glacial periods restricted further exploration of the TP.(4)Promoted by the warmer and wetter climate and the expansion of millet agriculture in the Yellow River Basin,human activity on the northeastern TP intensified significantly during the early-middle Holocene.During 6.0–5.0 ka,the favorable climatic conditions promoted millet agriculture which resulted in the intensification of human activity on the northeastern TP.However,the gradual cooling after~5.0 ka forced prehistoric human groups to migrate southward.During~4.2–3.6 ka,significant cooling events led to reduced human activity and the transformation of subsistence strategies.The establishment of a mixed arable-pastoral economy became the primary driver for the rapid expansion of the spatial range of human settlement and the intensity of human activity since~3.6 ka.Additionally,since 3.6 ka,increasing moisture on the northeastern TP and decreasing moisture on the southern TP promoted the development of agriculture and pastoralism in different ways in these regions,suggesting that the development of prehistoric human societies remained heavily dependent on regional climatic conditions.This study has important implications for understanding the relationship between environmental changes and human activities on the TP,and it helps address the challenges posed by future climate change,as well as contributing to China's“Belt and Road”initiative.

文摘Background:There are substantial regional differences in drinking alcohol in Russia,both at the population and individual levels.However,the causes of these differences have not been studied yet.Objective:The goal of our study was to examine the effect of regional living conditions on individual alcohol consumption by the population of Russia.Methods:For the analysis,we used data from a cross-sectional epidemiological study conducted in 2013-2014.The final analytical sample included 18,130 people aged 25-64 years.We conducted the interviews face to face,based on which any drinking in the last year,as well as alcohol abuse,were considered as a response.Alcohol abuse was recorded when the respondent consumed 5.75 or more grams of pure ethanol per day(75th percentile of average daily alcohol consumption among alcohol drinkers).The assessment of the regional living conditions was accomplished via integral indexing,which was previously performed based on publicly available data for 2010-2014.Associations were assessed using generalized scoring equations with unchanging standard errors.The associations were expressed by odds ratios(OR)and 95%confidence intervals(C).Results:Deterioration of social conditions and increase in demographic depression in the region of residence increased the odds of any drinking(OR 1.51,95%CI:1.33 to 1.72,P<0.001 and OR 1.22,95%CI:1.05 to 1.41,P=0.oo9,respectively).The odds of alcohol abuse increased with the deterioration of social living conditions and the growth of the industrial development in the region:OR 1.35,95%CI:1.14 to 1.59,P<0.001 and OR 1.16,95%CI:1.05 to 1.28,P=0.002,respectively.Conclusion:Our analysis allowed assessing the impact of the regional living conditions on individual drinking alcohol in the population of Russia.
文摘[Objective] The aim was to study on construction of overall water environment in Xi＇an. [Method] The study discussed necessity and basic principles of over-all restoration and construction of ＂Chang＇an Eight Water＂ from urban planning, and explored related methods from long term planning and concrete construction approaches. [Result] The study proposed that urban landscape substrates of ＂Chang＇ an Eight Water＂ should be restored based on overall planning about urban water environment, change of linear metabolism, and construction of drainage circulation system. Furthermore, self-circulation and purification of rainfall and sewage could be made use of there in view of present urban water environment. In addition, urban ＂metabolism＂ should be restored progressively to improve urban environment with consideration of water catchment, storage, and diversion. [Conclusion] We should take the initiative to catch the special opportunity to build Xi＇an into an international metropolis with overall planning, designing and implementation, which will be conducive to reconstruction of water system and pleasant surroundings, and to presentation of urban ecosystem and context in ＂Chang＇an Eight Water＂, providing many opportunities for urban development.
文摘To create a graceful living environment is the core responsibility of landscape designers in the designing process of residential environment. Residential environment design should pay attention to correctly involving cultural feature and environmental and ecological elements which should be integrated in certain living environment through a good design method, so as to reflect landscape designers’ concern on the urban living space. Taking the buildings of Urban Paradise (Paradise in Chinese literature is also called Taohua Yuan, that is, Land of Peach Blossom, originated from the essay by TAO Yuan-ming in the Eastern Jin Dynasty) in Nanning City for example, the research investigated how to integrate ecology and culture in the environment creation of residential district.

文摘The paleoenvironmental changes and adaptation strategies of hominins during the Late Pleistocene are crucial for understanding the evolution,dispersal,and behavioral shifts of early modern humans.Despite South China's significance as a nexus for hominin dispersal and handaxe technology diffusion,quantitative reconstructions of paleoenvironments linked to archaeological records remain scarce.The Sandinggai site(96.6-13.3 ka BP)in central South China,with its well-preserved stratigraphy and abundant lithic artefacts,is notable for providing valuable insights.In this study,quantitative reconstruction of the vegetation succession and climate change sequences at the site was conducted using palynological and isotopic data.The results indicated a shift from a warm-temperate evergreen and deciduous broadleaf mixed forest to a temperate deciduous broadleaf forest,with the climate transitioning from warm and humid to cooler and drier conditions.During the early phase,an increase in lithic production suggested favorable conditions for hominin survival.In the later phase,decreased lithic production and the replacement of large handaxe tools by smaller flake tools,indicated that hominins adapted to the cooler,drier climate and more open landscapes through lithic miniaturization.These findings highlight the environment-driven adaptation of lithic technology and hominin behavior,thereby shedding light on human survival adaptation strategies.
文摘The purpose of this study was to evaluate the roles of different housing environments in neurological function, cerebral metabolism, cerebral infarction and neuron apoptosis after focal cerebral ischemia. Twenty-eight Sprague-Dawley rats were divided into control group （CG） and cerebral ischemia group, and the latter was further divided into subgroups of different housing conditions： standard environment （SE） subgroup, individual living environment （IE） subgroup, and enriched environment （EE） subgroup. Focal cerebral ischemia was induced by the middle cerebral artery occlusion （MCAO）. Beam walking test was used to quantify the changes of overall motor function. Cerebral infarction and cerebral metabolism were studied by in vivo magnetic resonance imaging and 1H-magnetic resonance spectra, respectively. Neuron necrosis and apoptosis were detected by hematoxylin-eosin and TUNEL staining methods, respectively. The results showed that performance on the beam-walk test was improved in EE subgroup when compared to SE subgroup and IE subgroup. Cerebral infarct volume in IE subgroup was significantly larger than that in SE subgroup （P〈0.05） and EE subgroup （P〈0.05） on day 14 after MCAO. NAA/Cr and Cho/Cr ratios were lower in MCAO groups under different housing conditions as compared to those in CG （P〈0.05）. NAA/Cr ratio was lower in IE subgroup （P〈0.05） and higher in EE subgroup （P〈0.05） than that in SE subgroup. NAA/ Cr ratio in EE was significantly higher than that in IE subgroup （P〈0.05）. Cho/Cr ratio was decreased in MCAO groups as compared to that in CG （P〈0.05）. A significant decrease in normal neurons in cerebral cortex was observed in MCAO groups as compared to CG （P〈0.05）. The amount of normal neurons was less in IE subgroup （P〈0.05）, and more in EE subgroup （P〈0.05） than that in SE subgroup after MCAO. The amotmt of normal neurons in EE subgroup was significantly more than that in IE subgroup after MCAO （P〈0.05）. The ratio of TUNEL-positive neurons in EE was significantly lower than that in SE subgroup （P〈0.05） and IE subgroup （P〈0.05）. Correlation analysis showed that the beam walking test was negatively correlated with NAA/Cr ratio （P〈0.05）. Cerebral infarct volume was negatively correlated with both NAA/Cr ratio （P〈0.01） and Cho/Cr ratio （P〈0.01）. The amount of normal cortical neurons was positively correlated with both NAA/Cr ratio （P〈0.0I） and Cho/Cr ratio （P〈0.05）. The TUNEL-positive neurons showed a negative correlation with both NAA/Cr ratio （P〈0.01） and Cho/Cr ratio （P〈0.01）. This study goes further to show that EE may improve neurological functional deficit and cerebral metabolism, decrease cerebral infarct volume, neuron necrosis and apoptosis, while IE may aggravate brain damage after MCAO.

文摘China's escalating aging population has made home-based care the primary means of elderly support.However,current residential environments frequently fail to meet seniors'needs.Research on elderly housing lacks comparative studies across different demographic groups.This study employs the Delphi method to identify improvements for Age-Friendly Housing(AFH)and develops a Kano model questionnaire to analyze preferences among various age groups of elderly individuals.Additionally,it evaluates how living arrangements and health conditions impact these preferences.Results show that individuals aged 60-74 prioritize visual connections with the external environment and monitoring the surroundings outside their homes,while those aged 75 and above focus more on bathroom safety and indoor mobility.Seniors aged 60-74 living with children,and those aged 75 and above living with caregivers or in nursing homes,generally exhibit less concern for most design strategies.Conversely,seniors with arthritis,visual impairments,or hearing disabilities tend to favor design improvements more.Policymaking and implementation related to AFH should account for elderly individuals'diverse ages and living arrangements to set appropriate priorities,thereby aiding in optimizing resources and enhancing residents'satisfaction and quality of life.
