  • Regional cultural expression of cultural architecture—Take the design works of Yichang History and Culture Theme Exhibition Hall as an example

    Cultural buildings have distinct regional characteristics. How to make them have regional characteristics is an important point to judge the success or failure of a cultural building design. Take Yichang City’s cultural architecture design as an example to explore how regional cultural characteristics are reflected in the architecture. From the aspects of humanities and natural environment, we provide an in-depth analysis of the cultural design of local characteristics, and discuss the specific application of different factors in the design of stylistic architecture.

  • Hydroethanolic extract of Theobroma cacao beans is non toxic and attenuates oxydative stress induced by Naphtalene in Wistar rats

    Background: Oxidative stress is a situation where the cell no longer controls the excessive presence of toxic oxygen radicals. Many human diseases have a strong relationship with oxidative stress due to an imbalance between antioxidants and pro-oxidants. The objective of this study is to evaluate the in vivo antioxidant capacity of Theobroma cacao (T.cacao) beans extract and its acute toxicity. Methods: T. cacao beans were collected in the Obala locality (Center Cameroon) and then subjected to hydroethanolic extraction (70:30) at pH 3. The in vivo oxidative stress induction was done using naphthalene at 110 mg / kg and different doses of extracts (50 mg / kg, 100 mg / kg, and 200 mg / kg) were orally administered to rats. Some oxidative stress parameters helped to evaluate the antioxidant potential of the extract (superoxide dismutase (SOD), reduced glutathione (GSH) and malondialdehyde (MDA)). In addition, the acute toxicity of T. cacao was evaluated by the methods recommended by the ODCE. Test groups received respectively the extract at different doses (5000 mg / kg and 2000 mg / kg) against 10% of DMSO and distilled water as neutral controls. Hepatic function was assessed using transaminase assays (ASAT, ALAT), proteins and histological sections. Also the blood count allowed to explore the haematological function. Results: The administration of different doses of extracts or vitamin C as standard significantly increased GSH levels as well as antioxidant enzymes (SOD, CAT) and a significant decrease in MDA in studied organs and serum of animals compared to pro-oxidant control. ALAT and ASAT activities did not significantly vary in rats compared to neutral controls. No deaths and hepatic injuries were observed at different doses of the extracts. Conclusion: The extract of T. cacao beans possess in vivo antioxidant capacities capable of protecting tissues against oxidative stress and toxicity in…

  • Anti-bacterial Activity of Aqueous and Methanolic Root Extracts of Medicinal Plant Heteropogon contortus

    Synthetic drugs available for the treatment of chronic and infectious diseases are very expensive and some of them have become less effective due to the emergence of antibiotic resistance. Researchers are now focused on natural sources including plants and plant parts for the development of novel therapeutic agents. Therefore, this study evaluated in vitro anti-bacterial activity and phytochemical composition of aqueous and methanolic root extracts of Sri Lankan medicinal plant Heteropogon contortus against clinically significant pathogens, Escherichia coli (ATCC 25922) and Staphylococcus aureus (ATCC 25923). Agar well diffusion method and standard chemical tests were performed to evaluate anti-bacterial effect and phytochemical profile of the root extracts, respectively. The results revealed that each crude root extract exhibited anti-bacterial activity against both E. coli and S. aureus. The largest zones of inhibition against both E. coli and S. aureus were detected from the methanolic root extract at a concentration of 200 mg/mL and this is a novel finding. Phytochemical analysis of roots revealed the presence of bioactive constituents that account for the anti-bacterial potential, such as alkaloids, phenols and flavonoids. Thereby, root of H. contortus is a reliable source to develop potent, cheap and natural anti-bacterial agents. Future research focusing on high concentrations of different root extracts is recommended to further understand the anti-bacterial capability of H. contortus.

  • The Role of Maternal Stress, Cortisol and Interleukin-12 in Cases of Missed Abortion in the First Trimester of Pregnancy in Saudi Women

    Missed abortion in early pregnancy is a common gynecological condition, and the incidence has been increasing presenting itself as a public health problem. This study aimed to examine stress, cortisol concentration, and altered IL-12 levels in women who experienced missed abortions. Women with missed abortions (n = 40) were matched with control women of the same age in the same stage of pregnancy (n = 30). Participants filled out a survey about common stress factors. Venous blood samples were taken from the patients at 7:00 a.m. ELISA detected IL-12 concentrations, and serum cortisol was measured by electrochemiluminescence immunoassay. Women with missed abortions reported significantly more common stressors, and their serum cortisol and IL-12 concentrations were significantly higher than those of the women with healthy pregnancies (all P< 0.05). Receiver operating characteristic (ROC) analysis was used to assess the power of the studied parameters to predict women at risk for missed abortion. IL-12 performed the best in predicting women with missed abortions as it had the highest area under the curve (AUC), followed by cortisol. Stress and changes in the immune system may play a role in the etiology of missed abortion in Saudi women in early pregnancy.

  • The schedule of World Cup and its impact on the team

    This paper discusses the organization of the World Cup competition, in which through the establishment of a number of scheduling model, the use of analytic hierarchy process and stochastic simulation and other methods to solve this problem and obtain a more reasonable arrangement of the competition. For the arrangement of the Order of the game, first of all, the existing competition is studied. On the premise of the increase in the number of teams and the previous arrangement of the group points, it is considered from the appropriateness of the field, whether the schedule is wonderful, whether the arrangement is simple and whether the ranking is reasonable. 3 new competition competitions are proposed for the improvement of the original competition. Then, the analytic hierarchy process is used to compare and analyze the 3 new competition methods, and the optimal competition method is selected. Finally, under the previously established game, FIFA’s integral algorithm formula is used to analyze and calculate the impact of the results produced under the competition on FIFA rankings. In the application of formula calculation, the stochastic factor is introduced, and the results are simulated by computer, which can get the approximate upward trend of the team in different ranking intervals.

  • Study on the Impact of Climate Change on Regional Instability

    In this paper we will discuss the problem on how the regional instability of a country can be affected by the climate change. Based on the data collected about the national vulnerabilities, we select fifteen indicators by the principal component analysis. A new three-level indicator system is then established to assess the country’s vulnerability. To obtain and optimize the weight for each indicator used at different levels, the Analytic Hierarchy Process (AHP) and Gray Relational Analysis (GRA) are used. Based on this work, a measurement system including the climate, economic, security, politics and human development is set up to measure the vulnerability of the country.

  • Public Health aspects of Cesarean section including overuse and underuse of the procedure

    Caesarean section (CS) is lifesaving medical procedure that is able to avert both maternal and neonatal mortality. However, across the globe an estimated 3.2 million necessary CSs do not happen in low income countries and an estimate of 6.2 million unnecessary CSs happen in middle and high income countries. The overuse and underuse of this procedure driven by both the supply-side (such as resources within the health system, healthcare policy and strategies, health financing systems and perceptions of the healthcare professional) and demand-side (such as socio-economic status, population preference and perceptions and trust in health system) determinants. There are stark inequities in CS rates between and within regions and countries. Many regions across the globe (Eastern Asia, Northern Europe, Central America, Southern America, Northern America and Oceania) have over double recommended optimal rates, whereas several African regions (Eastern, Middle and Western) have dangerously low rates. Both of these have detrimental impacts on maternal and neonatal outcomes. There is a need now for health policy and decision makers at both national and facility level to try and optimize the CS rates through facilitating strategies that promote positive human relations and encourage standardized evidence based care.

  • An Experimental Investigation on Use of Bitumen Emulsion in the Construction of Gravel Road

    The base soil is one of the nature’s most common construction materials. Almost all types of construction are built with or upon the soil since centuries till today. The most important and effective part of a road pavement is sub grade soil, its strength and stability. If strength of soil is poor, then stabilization is normally needed. Sub grade is sometimes stabilized or replaced with stronger soil material so as to improve the strength. Such stabilization is also suitable when the available subgrade is made up of weak soil and hence has poor stability. Increase in the sub grade soil, strength may lead to economy in the structural thicknesses of a pavement. The most commonly used materials for soil stabilization are Cement, fly ash, lime, fibers, polymers etc. In the present study, an attempt has been made to improve the properties of the gravel soil by adding bitumen emulsion. An attempt has been made to use the emulsion for improving the strength of gravel soil expressed in terms of CBR values which may prove to be economical and give better results. In this study, the whole laboratory work revolves around the basic properties of soil and its strength in terms of CBR. A little cement added to provide better soil strength. It is observed that excellent soil strength results have been achieved by using cationic bitumen emulsion (CMS) with little quantity of cement used as filler. The appropriate mixing conditions for gravelly soil with CMS bitumen emulsion are being first attempted. This is followed by deciding four particular material conditions to show the variation in dry density and CBR value to achieve the best possible strength properties of gravel soil.

  • Should We Build Our School Here? Children’s Level of Fitness, School Site-Typology and the Built Environment

    Background: No prior studies have assessed the relationship of school-sites with children’s fitness, nor evaluated how it is influenced by types of built environments surrounding school-sites. Purpose: To create a typology of school-sites and assess their associations, with school-level cardiorespiratory fitness (PACER score), as well as 34 environmental measures, reflecting food retailers and parks. Methods: PACER scores (#laps) were obtained on 20,900 children, 5-18 years-old, attending 103 rural and urban public schools in Wisconsin 2009-2010. Scores were aggregated at the school-level (mean 25.2±10.5). School-site typology reflects walkability context and parcel size. Schools were classified as: Neighborhood-School, Neighborhood-Campus, Neighborhood-Suburban, or Campus-School. Geospatial and linear regression were performed , overall and by sex and age strata, using a 1600-meter circular buffer around each school. Associations with school-level-PACER score were assessed for school types; density of unhealthy and healthier food retailers; and types of parks. Results: Campus-Schools predict a school average-PACER 7 laps significantly higher than Neighborhood-schools. ‘Neighborhood-Campus’ showed the lowest PACER for males and 11-13 years-old (10 and 12 laps lower). Negatively correlated with average-PACER were, unhealthy convenience stores for both sex, large parks for females. More fast-casual restaurants predict higher average-PACER. Schools with more students predict higher average-PACER for males and 6-10 years-old. Conclusion: Among Wisconsin schools, school-site and its context are associated with children’s physical fitness, suggesting that school-siting should include a health benefit analyses in the process. This study demonstrates the utility of school-level PACER scores and suggests further study of the mechanisms by which children’s fitness is influenced by food retailers around school zones.
