Multimodal Treatment of Cystic Echinococcosis

Cystic echinococcosis is a zoonotic disease that is caused by the larval stages of cestodes species and belongs to the genus Echinococcus. Echinococcus granulosus (E. granulosus) causes cystic echinococcosis which is global and wider in its distribution than alveolar echinococcosis. Endemic areas of E. granulosus are Russia, Eastern Europe, the Middle East, China, and South America based on data from the World Health Organization (WHO). Incidence rates are 50 per 100,000 person-years. The life cycle of E. granulosus requires both an intermediate host and a definitive host. A human accidentally becomes an intermediate host. Upon infection, cyst formation mostly occurs in the liver (70%). At the first, the infection is usually asymptomatic. Diagnosis of cystic echinococcosis can be done by imaging techniques (ultrasound or CT/MRI), serum serologic testing for antibodies against hydatid antigens, and immunologic testing. In general, there are four different management modalities for cystic echinococcosis, such as surgery, percutaneous therapy surgery, chemotherapy, and watchful waiting.

Genetic Diversity and Population Structure of the Slender Racer (Orientocoluber spinalis) in South Korea

The slender racer, Orientocoluber spinalis, is a monotypic species found in northeast Asia. We collected 67 O. spinalis samples from the Republic of Korea (hereafter, South Korea) and 7 from China and Mongolia and investigated their genetic diversity and population structure. In South Korea, O. spinalis populations were mainly found on Oeyeondo, Uido, and Udo islands and Woraksan Mountain and showed low genetic diversity in the analysis of concatenated mitochondrial sequences of the cytochrome b (Cytb) and NADH dehydrogenase subunit 4 (ND4) genes. Orientocoluber spinalis populations in South Korea showed low differentiation and likely diverged recently. Orientocoluber spinalis may have colonized the Korean Peninsula from China and Mongolia, but this route is not confirmed due to the lack of samples from the Democratic People’s Republic of Korea and middle eastern China. Considering its extreme rarity, low population density, and low genetic diversity, O. spinalis should be designated an endangered species in South Korea, as it is in Russia, Mongolia, and Kazakhstan.

Civilizationism and the Ideological Contestation of the Liberal International Order

Abstract Discourses and practices reproducing a world where a plurality of distinct civilizations clash or dialogue, rise or fall, color multiple facets of global politics today. How should we interpret this unexpected surge in civilizational politics, especially notable in the United States, Europe, the Middle East, China, and Russia? This paper argues that the growing turn to civilizations or, better, civilizationism should be understood as a counter-hegemonic ideological reaction to the globalization of the liberal international order. It theorizes the deepening and widening of the liberal international order in the aftermath of the Cold War as enabled by powerful constitutive ideological forces, which congeal into a distinctively modern, informal, universal standard of civilization. This liberal civilizational standard can be experienced by a particular category of non (fully) liberal actors within and beyond the West as ideologically entrapping them—through processes of socialization or stigmatization—in a state of symbolic disempowerment. The paper shows how civilizationism provides an ideological path for resisting and contesting the liberal standard of civilization by articulating a distinct and valued (essentialized) sense of collective belonging, and an alternative (generally illiberal) normative system and (broadly multipolar) vision of international order. Along with theorizing and exploring in original ways the drivers of civilizational politics in the current historical juncture, the paper makes two further contributions. It highlights and unpacks the key role of ideological dynamics in the making and contestation of international orders in general and the liberal one in particular. It suggests and shows why civilizations are best approached as ideological constructs rather than cultures, identities, or discourses.

A Comparative Study of Chinese and Europe Funeral Etiquette and Customs: Ming Dynasty and Renaissance

In the late Middle Ages, China and Europe attached great importance to matters related to people’s burial after death, and the religious and secular rulers in the two regions were no exception. The mausoleum system in the two places is generally composed of written inscriptions and visual stone carvings of cemetery statues. By the comparative research, we can find that inscriptions of Chinese emperors in Ming Dynasty highlight the emperor’s personal achievements and family continuity characterized by filial piety, while inscriptions on papal tombs in Renaissance period highlight whether what the pope did as a Christian was in line with God's will. These both are the most important part in their ruling, especially for its own continuation.

Türkiye's Middle Corridor and China's BRI: Identification and Assessment

China’s Belt and Road Initiative (BRI) and Türkiye’s Middle Corridor (MC) are two ambitious initiatives that foster trans-continental integration. These two grand schemes have been developed independently of one another. Nonetheless, they have the common objective of connecting Europe and Asia as well as facilitating commercial, economic, political, and socio-cultural interactions between the two continents. While the MC is one of the most important components of the BRI, the alignment of these two projects will offer a range of benefits for Türkiye’s MC, especially in finding alternative financing sources. This article aims to examine the history, objectives, and phases of Türkiye's MC. In doing so, it harmonizes the BRI with the MC and examines the opportunities that the integration offers for the region, as well as its inherent risks and challenges. This research is also significant and worthwhile as it provides insights into the compatibility of the BRI and the MC.

Diversifying the historical geography of exploration: Subaltern body work on British-led expeditions c.1850–1914

Knowledge production on Victorian and Edwardian expeditions depended on the embodied labour of subaltern individuals. Explorers frequently mention such work in their accounts, but they also manage their dependence on others through a variety of rhetorical techniques. I show that focusing on body work can foreground the contributions of subaltern individuals to the history of British geographical exploration. I do so through a critical reading of the published and private accounts of explorers as well as their visual sources. In focusing on these labour practices, this paper offers a new perspective on the historical geographies of exploration, attentive to subaltern contributions. More broadly, the paper encourages geographers to reflect on the embodied and caring labour on which geographical research depends and the devaluation of certain bodies and their labour. These issues are examined through new readings of three otherwise familiar case studies: Richard Burton and John Hanning Speke's Nile expeditions (1856–59 and 1860–63); Isabella Bird Bishop's travels in the Middle East, Japan, China, and Lesser Tibet (1878–1896); and Captain Scott's two Antarctic expeditions (1901–04 and 1911–13).

A journey through the Ordovician System around the world

Abstract The Ordovician was a key period in the biological and geological history of the Earth. ‘A Global Synthesis of the Ordovician System’ is presented in two volumes of The Geological Society, Special Publications series. The first volume (SP532) covers general aspects of the Ordovician and also includes the syntheses of the Ordovician successions of Europe. To provide a comprehensive global overview, this second volume (SP533) represents a journey through the Ordovician System around the world. Reviews of the Ordovician of North America include syntheses of Alaska, Greenland, Canada, the USA and Mexico, whereas the South American Ordovician is summarized in a specific chapter related to Argentina and neighbouring countries. The Ordovician System of Africa is presented in chapters covering the north and the south of the continent where significant Ordovician successions occur. Australia and New Zealand, as well as Antarctica, are visited in separate chapters. Asia provides the most complex Ordovician successions that are reviewed in chapters covering Turkey and the Levant region, the Middle East, Central Asia, Kazakhstan, India, SE Asia, China, Korea, and Japan. Our journey covers a great number of locations but, with many successions still to be fully described, our knowledge of the Ordovician of the world remains incomplete.

A Post‐American Middle East? US Realities Vs. Chinese and Russian Alternatives

AbstractFor the past 15 years, there have been increasing calls for the United States to reduce its overseas force structure and to bring troops home. Such discussion accelerated during the Trump administration, and perceptions of American retrenchment were heightened by President Joe Biden's decision to withdraw from Afghanistan. This article asks the key question: Is Washington really engaging in a systematic pullout from the Middle East? Based on publicly available evidence, I argue that, contrary to common perceptions, the American military is actually increasing its forward presence in the Arabian Peninsula and Gulf region. In addition, I contend that the two other states that have the potential to replace the United States in the Middle East, Russia and China, are for multiple reasons incapable of doing so. In addition to puncturing the myths, the article contributes to the ongoing policy debates and theoretical literatures regarding Middle East security and great‐power competition.

Retrieval of TP Concentration from UAV Multispectral Images Using IOA-ML Models in Small Inland Waterbodies

Total phosphorus (TP) concentration is high in countless small inland waterbodies in Hubei province, middle China, which is threating the water environment. However, there are almost no ground-based water quality monitoring points in small inland waterbodies, because the cost of time, labor, and money is high and it does not meet the needs of spatiotemporal dynamic monitoring. Remote sensing provides an effective tool for TP concentration monitoring spatiotemporally. However, monitoring the TP concentration of small inland waterbodies is challenging for satellite remote sensing due to the inadequate spatial resolution. Recently, unmanned aerial vehicles (UAV) have been applied to quantitatively retrieve the spatiotemporal distribution of TP concentration without the challenges of cloud cover and atmospheric effects. Although state-of-the-art algorithms to retrieve TP concentration have been improved, specific models are only used for specific water quality parameters or regions, and there are no robust and reliable TP retrieval models for small inland waterbodies at this time. To address this issue, six machine learning methods optimized by intelligent optimization algorithms (IOA-ML models) have been developed to quantitatively retrieve TP concentration combined with the reflectance of original bands and selected band combinations of UAV multispectral images. We evaluated the performances of models in terms of coefficient of determination (R2), root mean squared error (RMSE), and residual prediction deviation (RPD). The results showed that the R2 of the six IOA-ML models for training, validation, and test sets were 0.8856–0.984, 0.8054–0.8929, and 0.7462–0.9045, respectively, indicating the methods had high precision and transferability. The extreme gradient boosting optimized by genetic algorithm (GA-XGB) performed best, with the highest precision for the validation and test sets. The spatial distribution of TP concentration of each flight derived from different models had similar distribution characteristics. This paper provides a reference for promoting the intelligent and automatic level of water environment monitoring in small inland waterbodies.

Simulation Analyses on a Downburst Event That Caused a Severe Tower Toppling down Accident in Zhejiang (China)

The downburst events have been a research focus for decades, as their associated disastrously strong winds pose a great threat to aviation, the shipping industry, agriculture, and the power industry. On 14 May 2021, a series of severe convection occurred in middle and eastern China, during which six 500-kilovolt transmission line towers in Zhejiang were toppled down by a downburst event, resulting in a large range of power outages. By using the Weather Research and Forecasting (WRF) model version 4.4, key features of the downburst event were reproduced reasonably; based on which, we explored the evolutionary mechanisms and the three-dimensional structures of the strong winds associated with the downburst event. It was found that a southwest–northeast-orientated, eastward moving strong squall line was the parent convection system for the downburst event. The downburst-associated convection was deep (from surface to 200 hPa); in the near surface layer, it was mainly associated with positive geopotential height and negative temperature deviations, whereas, at higher levels, it was mainly associated with negative geopotential height and positive temperature deviations. Backward trajectory analysis indicates that the air particles that came from the middle troposphere west of the key region (~61.2% in proportion) were crucial for producing the strong winds of the downburst event. These air particles experienced notable descending processes, during which most of the air particles decreased notably in their potential temperature, while they increased significantly in their specific humidity. The kinetic energy budget analyses denote that, for the region surrounding the location where the tower toppling appeared, the work done by the strong pressure gradient force between the high-pressure closed center (corresponding to intense descending motions) and the low-pressure closed center (corresponding to strong latent heat release) dominated the rapid wind enhancement.

Revisiting the Early Uses of Writing in Society Building: Cuneiform Culture and the Chinese Imperium.

This plenary address reconsiders the impact of writing on culture and governance in the ancient Middle East and China.

Multifractal Characteristics Analysis of Spatial State of Prefecture-Level Cities in China.

In the last 40years, Chinese cities have seen extensive development across a wide array of spheres. In this study, we applied a power-law and multifractal analysis to characterise 22 indices for 288 prefecture-level cities in mainland China. The data used to characterise the indices is representative of the year 2012. The results show that the Gross domestic product (GDP) is regular and exhibits multifractal spatial characteristics. Specifically, most developmental fields exhibit coupling in conjunction with being chaotic. Furthermore, eight indices with multifractal characteristics clearly reflect the spatial complexity of the corresponding fields and the volatility between prefecture-level cities. Overall, the tertiary industry has undergone nongeneralised development. On the other hand, the construction industry resembles a bubble economy, and the spatial layout of traditional industries has a homogenising effect in Middle and East China. This study examines China's overall spatial characteristics and states based on the above-mentioned analyses; additionally, the study focuses on the early 2010s. The contribution of this study provides a quantitative analysis paradigm based on a multifractal approach.

Residents Consumption Analysis and Countermeasures under Impact of Covid-19

Residents consumption analysis is important to a country to measure the indicators of national accounts. It can reflect the economic development level of the country and the residents’ current living standards. Since the start of 2020, Covid-19 has sweep across the globe. It has great negative impact on the both economic and consumption of China and whole world. This epidemic situation not only influences the resident’s consumption level, but also affects the consumption type and consumption patterns. Hunan province is in the middle of China and has large population base. So, this paper takes Hunan province as an example to compare the resident’s consumption ability and pattern before and after the Covid-19. Giving suggestions for the countermeasures and future policies.

Polymorphism analysis of the chloroplast and mitochondrial genomes in soybean

BackgroundSoybean is an important protein- and oil-rich crop throughout the world. Much attention has been paid to its nuclear genome, which is bi-parentally inherited and associated with many important agronomical traits. However, less is known about the genomes of the semi-autonomous and essential organelles, chloroplasts and mitochondria, of soybean.ResultsHere, through analyzing the polymorphisms of these organelles in 2580 soybean accessions including 107 wild soybeans, we found that the chloroplast genome is more variable than the mitochondrial genome in terms of variant density. Consistent with this, more haplotypes were found in the chloroplast genome (44 haplotypes) than the mitochondrial genome (30 haplotypes). These haplotypes were distributed extremely unevenly with the top two haplotypes (CT1 and CT2 for chloroplasts, MT1 and MT2 for mitochondria) accounting for nearly 70 and 18% of cultivated soybean accessions. Wild soybeans also exhibited more diversity in organelle genomes, harboring 32 chloroplast haplotypes and 19 mitochondrial haplotypes. However, only a small percentage of cultivated soybeans shared cytoplasm with wild soybeans. In particular, the two most frequent types of cytoplasm (CT1/MT1, CT2/MT2) were missing in wild soybeans, indicating that wild soybean cytoplasm has been poorly exploited during breeding. Consistent with the hypothesis that soybean originated in China, we found that China harbors the highest cytoplasmic diversity in the world. The geographical distributions of CT1–CT3 and MT1–MT3 in Northeast China were not significantly different from those in Middle and South China. Two mitochondrial polymorphism sites, p.457333 (T > C) and p.457550 (G > A), were found to be heterozygous in most soybeans, and heterozygosity appeared to be associated with the domestication of cultivated soybeans from wild soybeans, the improvement of landraces to generate elite cultivated soybeans, and the geographic adaptation of soybean.ConclusionsThe haplotypes of thousands of soybean cultivars should be helpful in evaluating the impact of cytoplasm on soybean performance and in breeding cultivars with the desired cytoplasm. Mitochondrial heterozygosity might be related to soybean adaptation, and this hypothesis needs to be further investigated.

Analysis of Digital Finance, Regional Heterogeneity and Urban Household Consumption Based on Chinese Financial Panel Data

Consumption plays an important role in economic growth. Using the Chinese panel data, we examined digital finance’s influence on urban household consumption at the national and regional levels. Digital finance is conducive to increasing urban residents’ consumption. The impact of the coverage breadth, usage depth, and digitization level of digital finance on household consumption is stronger in East China than in middle China and West China. In East China, the impact of the digital financial payment business, insurance business, and monetary fund business on household consumption is positive. Overall, digital financial products have a stronger role in increasing household consumption in East China than in other regions.

Comparative growth analysis of cumin plants (Cuminum cyminum L.) treated with glycerol and talc based phosphate solubilizing bacterial consortia

Cumin (Cuminum cyminum L.) is a versatile annual herb cultivated in the Middle East, India, China, and Tunisia. The seeds of this plant are primarily used in cooking as common food additives and traditional medicines to treat hypolipidemia, cancer and diabetes. However, cumin plants have poor germination and weak establishment rate, particularly under drought stress. The present study aimed to examine the growth promotion potential of cumin plants treated with talc and glycerol-based phosphate solubilizing bacteria (PSB) consortia. Four efficient PSB were isolated from the rhizosphere of Calotropis procera and Solanum lycopersicum and identified through 16S rRNA sequencing as Pseudomonas nitritireducens MF351819, Klebsiella pneumoniae MF351845, Erwinia sp. MF351846 and Pantoea dispersa MF351847. In a nursery experiment on cumin (Cuminum cyminum) plants, 15 treatments of single, dual, triple and quadruple combinations of four PSB isolates were formulated on glycerol and talcum powder-based bacteriological carriers. The 100-day pot experiment was initiated during the winter of 2016 (the last week of October) containing loamy sand soil of Sardarkrushinagar, Gujarat. The formulations were applied to pot soil containing seven-day-old cumin seedlings. With glycerol-based PSB inoculations, the P14 treatment containing a consortium of K. pneumoniae MF351845, Erwinia sp. MF351846, and P. dispersa MF351847 provided the highest per plant seed yield of 0.19 g. With talc-based PSB inoculations, the P11 treatment containing a consortium of K. pneumoniae MF351845, Erwinia sp. MF351846, and P. nitritireducens MF351919 produced the highest per-plant cumin seed yield of 0.42 g. Overall, talc-based PSB consortial treatments improved height, dry weight, 100 seed weight and yield of the cumin plant.

Life Cycle Greenhouse Gas Emission Assessment for Using Alternative Marine Fuels: A Very Large Crude Carrier (VLCC) Case Study

The International Maritime Organization (IMO) has set decarbonisation goals for the shipping industry. As a result, shipowners and operators are preparing to use low- or zero-carbon alternative fuels. The greenhouse gas (GHG) emission performances are fundamental for choosing suitable marine fuels. However, the current regulations adopt tank-to-wake (TTW) emission assessment methods that could misrepresent the total climate impacts of fuels. To better understand the well-to-wake (WTW) GHG emission performances, this work applied the life cycle assessment (LCA) method to a very large crude carrier (VLCC) sailing between the Middle East and China to investigate the emissions. The life cycle GHG emission impacts of using alternative fuels, including liquified natural gas (LNG), methanol, and ammonia, were evaluated and compared with using marine gas oil (MGO). The bunkering site of the VLCC was in Zhoushan port, China. The MGO and LNG were imported from overseas, while methanol and ammonia were produced in China. Four production pathways for methanol and three production pathways for ammonia were examined. The results showed that, compared with MGO, using fossil energy-based methanol and ammonia has no positive effect in terms of annual WTW GHG emissions. The emission reduction effects of fuels ranking from highest to lowest were full solar and battery-based methanol, full solar and battery-based ammonia, and LNG. Because marine ammonia-fuelled engines have not been commercialised, laboratory data were used to evaluate the nitrous oxide (N2O) emissions. The GHG emission reduction potential of ammonia can be exploited more effectively if the N2O emitted from engines is captured and disposed of through after-treatment technologies. This paper discussed three scenarios of N2O emission abatement ratios of 30%, 50%, and 90%. The resulting emission reduction effects showed that using full solar and battery-based ammonia with 90% N2O abatement performs better than using full solar and battery-based methanol. The main innovation of this work is realising the LCA GHG emission assessment for a deep-sea ship.

Anterior chamber parameters in cataract surgery candidates from middle China.

To determine the distribution of the anterior chamber parameters and associated factors in cataractous adults from middle China. In this cross-sectional study, axial length, anterior chamber depth (ACD) and lens thickness (LT) were measured with IOLMaster 700. The Pentacam HR was designed to measure the anterior chamber volume (ACV) and anterior chamber angle (ACA). Patients' data were collected and analyzed between 2020 and 2022. A total of 157 eyes of 157 Chinese adults (mean age: 64.43 ± 12.16 years) with a cataract were enrolled in this study. The mean values measured were as follows: axial length, 24.10 ± 2.44mm; ACD, 2.99 ± 0.52 mm; LT, 4.51 ± 0.48 mm; ACV, 113.98 ± 45.12 mm3; ACA, 32.33 ± 7.66 degrees. The ACD and ACV were statistically significantly greater in men than in women and had a decrease trend as age and LT increased. In the simulated linear equation of age with ACD and LT the absolute slope coefficients of equations were the same; however, the directions were opposite. The mean ACV was <100 mm3 when the patients were over 60 years. In the multivariate regression analysis of ACD, ACV and ACA there was a reasonable prediction with adjusted R2 = 0.878, 0.847 and 0.564, respectively. This study may provide normative data for cataract patients. The profile of anterior chamber can help improve the knowledge of the risk of angle closure in cataract candidates.

Watershed-Scale Shallow Groundwater Anthropogenic Nitrate Source, Loading, and Contamination Assessment in a Typical Wheat Production Region: Case Study in Yiluo River Watershed, Middle of China

Nitrate pollution in groundwater has become a global concern for agriculture and regional ecology. However, tracing the spatiotemporal groundwater nitrate pollution sources, calculating the total nitrogen loading, and assessing contamination at the watershed scale have not been well documented. In this study, 20 groundwater samplings from 2020 to 2021 (in dry and wet seasons) on the Yiluo River watershed in middle China were collected. Tracing groundwater nitrate pollution sources, calculating total nitrogen loading, and assessing contamination using dual isotopes (18ONO3 and 15NNO3), conservation of mass, and the nitrate pollution index (NPI), respectively. The results indicated that there were three nitrate sources in groundwater: (1) manure and sewage waste input (MSWI), (2) sediment nitrogen input (SNI), and (3) agriculture chemical fertilizer input (ACFI) in the Yiluo River watershed. ACFI and SNI were the main groundwater nitrogen pollution sources. The average nitrogen loading percentages of ACFI, SNI, and MSWI in the whole watershed were 94.7%, 4.34%, and 0.96%, respectively. The total nitrogen loading in the Yiluo River watershed was 7,256,835.99 kg/year, 4,084,870.09 kg/year in downstream areas, 2,121,938.93 kg/year in midstream areas, and 1,050,026.95 kg/year in upstream areas. Sixty percent of groundwater in the Yiluo River watershed has been polluted by nitrate. Nitrate pollution in midstream areas is more severe. Nitrite pollution was more serious in the wet season than in the dry season. The results of this study can provide useful information for watershed-scale groundwater nitrogen pollution control and treatment.

Insight into Population Structure and Evolutionary Analysis of the Emerging Tomato Brown Rugose Fruit Virus.

A total of 112 symptomatic tomatoes (Solanum lycopersicum L.) and 83 symptomatic pepper (Capsicum spp.) samples were collected in Ankara, Eskişehir, Bartın, and Zonguldak provinces of Turkey during 2020-2021. Six tomatoes and one pepper sample (3.6%) tested positive for tomato brown rugose fruit virus (ToBRFV, genus Tobamovirus) infection by DAS-ELISA and RT-PCR. ToBRFV-positive tomato and pepper plants were removed from greenhouses as soon as possible, and the greenhouses and tools were disinfected completely. Phylogenetic analysis on the complete CP sequences suggested the clustering of 178 GenBank isolates and 7 novel isolates into three groups. A study using DnaSP software showed very low genetic variation among current global ToBRFV isolates. All four ORFs of the virus genome were under strong negative evolutionary constraints, with a ω value range of 0.0869-0.2066. However, three neutrality tests indicated that most populations of the newly identified ToBRFV are currently expanding by assigning statistically significant negative values to them. The very low FST values (0.25 or less) obtained by all comparisons of the isolates from Europe, the Middle East, China, and America concluded that there is no clear genetic separation among currently known isolates from different geographic origins. The divergence time of ToBRFV was estimated to be in the middle of the course of the evolution of 11 tested tobamoviruses. The time to the most recent common ancestors (TMRCAs) of ToBRFV were calculated to be 0.8 and 1.87 with the genetically closest members of Tobamovirus. The results of this study could improve our understanding on the population structure of the emerging ToBRFV.
