Rice callus suspension cultures(RCSC) and seed extracts prepared from aromatic rice varieties were used to evaluate the cytotoxic impact on human colon and lung cancer cell lines, as well as a normal control cell line, using Taxol as a positive control. RCSC and seed extracts from two Indian aromatic rice varieties were applied at different concentrations to treat the cancer cell lines and normal lung fibroblasts over varying time intervals. Apoptosis was assessed in 1:5 dilutions of the A549 and HT-29 cell lines treated with RCSC for 72 h, using propidium iodide staining and flow cytometry. RCSC showed a more potent cytotoxic effect than seed extracts with minimal effect on the normal cell line, in contrast to Taxol. Confocal microscopy and flow cytometry further confirmed the apoptotic effect of RCSC. Gas chromatography-mass spectrometry-based metabolic profiling identified metabolites involved in cytotoxicity and highlighted altered pathways. RCSC is proposed as an alternative source for the development of novel anticancer drugs with reduced side effects.展开更多

The novel method of producing meat through culture reduces the need for animals to produce muscle fiber, thereby obviating the necessity for animal slaughter. Apart from its ethical advantages, cultured meat presents a possible way to fulfill the expanding need for food among growing populations. The purpose of this research was to find out whether Turkish students would be willing to pay for and accept cultured meat. Technique: Method: 371 university students who willingly consented to fill out a questionnaire and provide demographic data make up the research sample. Questions from previous studies on the acceptability of cultured meat were compiled to create the survey. The research’s data collection took place in March and April of 2022. The research was completed in June 2022 after the data had been processed and analyzed. Results: The results showed that the majority of participants were female and had omnivorous eating habits. Based on the results of the Bonferroni correction test, students with a higher intention to purchase and consume cultured meat were those who received economics and business education. Students with two years of university education had a higher overall survey score than those with four years of education (p < 0.05). Furthermore, it is discovered that there is a negative correlation between the participants’ ages and their Factor 2 (using cultured meat as an alternative to industrial meat) and Factor 3 (consuming and purchasing it) section points (r = -109, p = 0.036) (r = -0.121, p = 0.019). In conclusion, university students generally have a negative outlook on health-related issues, such as eating cultured meat as an alternative.展开更多

Facilities and well trained staff have been shown to be one of the major obstacles in the rapid and quality diagnosis of these diseases. As such, we carried out an analysis to compare the Widal test and stool culture to identify febrile patients with Salmonella infection. Method: A cross sectional study was conducted to diagnose salmonella infection with out-patients who demonstrated signs of salmonella infection. Serum was harvested from blood collected from 368 (Vina = 234, Mayo Banyo 65, and Djerem = 69) patients accompanied by stool, Widal test was conducted on the spot and stool was taken to a reference laboratory for culture using standard microbiological methods, sociological set up was calculated in percentages, prevalence was calculated using excel while statistical difference was calculated using SPSS. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated to compare the Widal test against stool culture. Results: A total of 368 (50.8% females and 49.2% males) participants took part in the survey. Salmonella prevalence (66.24%) in stool culture in the Vina division was significantly different (p 0.05). The sensitivity,specificity, PPV, and NPV of slide agglutination test against stool culture varied from different areas (Vina: 51.6%, 73.62%, 79.21% and 43.61%;Mayo Banyo: 60.53%, 77.78%, 79.31% and 58.33%;Djerem: 53.18%, 83.73% 73.91% and 67.39%) respectively. Slide agglutination test has a fair agreement with the stool culture (kappa, Vina = 0.202;Mayo Banyo = 0.37 and Djerem = 0.38). Conclusion: Generally, in the three areas of study, the Widal test had a fair correlation with the stool culture;This means the Widal test should not be used alone but in combination with stool culture in the detection of salmonella infections.展开更多

These cultures, with their unique primitiveness distinct from modern culture, often attract tourists. This study integrates the indigenous Yami culture of Lanyu Island, Taiwan Region, into innovative designs from the perspective of tourists’ understanding of the local culture. In this way, tourists can experience the harmonious coexistence of the Yami tribe and nature, while these culturally rich products foster deeper experiential and emotional resonance. This study employs the Mandala thinking method for concept expansion and the Osborn checklist method for the analysis and transformation of design elements. Subsequently, designers were invited to conduct on-site travel experiences, leading to the creation of a series of Yami cultural products. Through the evaluation and validation of cultural product assessment indicators, functional commercialized products were ultimately produced. This study aims to establish a design process for cultural products through this design case. It seeks to help users recall their Lanyu Island travel experiences and appreciate the often-overlooked cultural beauty, thereby raising awareness of cultural preservation.展开更多

In an effort to address this issue, researchers turned to corn starch as a thickening agent, discovering that a concentration of 2.0% effectively improved the viscosity and significantly reduced syneresis in stirred camel milk yoghurt and cultured camel milk. This study explores alternatives to corn starch, focusing on butternut squash seeds as a promising substitute due to their hydrocolloid composition. By incorporating butternut squash (Cucurbita moschata) seed powder (BSSP) as a thickening agent, this study aimed at enhancing the chemical and rheological properties of stirred camel milk yoghurt and cultured camel milk. Fermented camel milk was prepared using 4 litres of camel milk, 2% starter cultures (thermophilic culture for yoghurt and mesophilic aromatic culture for stirred cultured camel milk) and BSSP 0.0% (negative control), 0.4%, 0.8%, 1.2%, 1.6%, 2.0% mixed with 0.4% gelatin. 2.0% corn starch mixed with 0.4% gelatin was used as a standard for comparison. Results showed that increasing the BSSP level significantly (p < 0.05) decreased the moisture content while increasing the total solid content of stirred fermented camel milk products. There was an increase in ash content with an increase in BSSP levels. There was a significant (p < 0.05) reduction in the pH, with an increase in BSSP levels in stirred fermented camel milk samples. Increasing the concentration of BSSP from 0.4% to 2.0% resulted in a significant (p < 0.05) increase in viscosity and a reduction in syneresis of stirred camel milk yoghurt and stirred cultured camel milk samples. This study demonstrated that BSSP effectively enhances the viscosity, reduces syneresis and increases acidity in stirred fermented camel milk products during storage.展开更多

文摘This study delves into the intricate dissemination and acceptance of Dongpo Culture,epitomized by Su Shi,in the UK and the US,aiming to bolster the global recognition of Chinese literary and cultural values and advance the national strategy of“Going Out”.Su Shi’s multifaceted contributions—spanning literature,philosophy,calligraphy,and art—serve as a pinnacle of Northern Song Dynasty culture.This research evaluates the varied translations,monographs,biographies,journal articles,and doctoral dissertations about Su Shi in these Western nations,using literature analysis,typical analysis,and comparative methods.The findings reveal a robust interest in Su Shi studies in the US,marked by a proliferation of scholarly works and translations across diverse disciplines,such as literature,art,and aesthetics,establishing the US as a leading center for Dongpo Culture studies.Conversely,the UK,despite its early engagement,shows limited scholarly outputs and significant research papers on the subject.By examining Dongpo Culture’s overseas communication path and influence paradigm,this paper seeks to enhance China’s cultural soft power and self-confidence.It underscores the vital role of international cultural exchange in constructing a positive image of China’s national identity,facilitating its peaceful rise,and providing strategic insights for the global promotion of Chinese culture.
文摘Yi Village in Kelantan State,Malaysia,is known for its batik production.Batik is a wax-dyed fabric that evolved from sarong garments.To make batik,artisans first use melted wax to draw various lines and patterns on white or pre-dyed fabric,then fill in different colors between the lines.Then,the fabric is placed under the sun to dry.

文摘The effects of 5 lactic acid bacteria(LAB)fermentation on the pasting properties of glutinous rice flour were compared,and suitable fermentation strains were selected based on the changes of viscosity,setback value,and breakdown value to prepare LAB compound starter cultures.The results revealed that Latilactobacillus sakei HSD004 and Lacticaseibacillus rhamnosus HSD005 had apparent advantages in increasing the viscosity and reducing the setback and breakdown values of glutinous rice flour.In particular,the compound starter created using the two abovementioned LAB in the ratio of 3:1 had better performance than that using a single LAB in improving the pasting properties and increasing the water and oil absorption capacity of glutinous rice flour.Moreover,the gelatinization enthalpy of the fermented samples increased significantly.For frozen glutinous rice dough stored for 28 days,the viscoelasticity of frozen dough prepared by compound starter was better than that of control dough,and the freezable water content was lower than that of control dough.These results indicate that compound LAB fermentation is a promising technology in the glutinous rice-based food processing industry,which has significance for its application.
文摘The culture wars that simmer within any nation may have been escalating recently;but regardless of their national settings or milieus,many of these wars are informed by two opposing paradigms of culture.This paper analyzes two of these leading paradigms,designated here as Regressivism and Progressivism.Other theorists have long chronicled the differing strengths and weaknesses of these paradigms,taking the former as expressing more conservative,traditional,and nationalistic values,and the latter as expressing more liberal,pluralistic,and cosmopolitan values.Going beyond these perennial distinctions,I argue that Progressivism is more benign and beneficial than the former-by meeting basic human needs better and supporting more effective adaptation to changing exigencies.I also argue that Progressivism does not express merely subjective or relativistic preferences and values,but objectively preferable and quantifiable ones,that benefit not only our personal lives more but also our global village and communal lives more.

文摘Urban night tourism is a new form of urban tourism development and an important driving force for the prosperity of urban night economy.As the most prestigious business card among many night tour projects in Guangzhou,the Pearl River water night tour has contributed to the development of Guangzhou s night economy,which cannot be underestimated.However,in the process of rapid development,there are also problems such as diversified operators,insufficient integration of intangible cultural elements,excessive commercial attributes,issues of tourism facilities and service facilities.Under the new stage of integrated development of culture and tourism,how to use mutual promotion of culture and tourism in the Pearl River night tour to seek innovative paths for high-quality development in the future is the main problem expected to be solved in this paper.Therefore,based on the perspective of culture and tourism integration,this paper analyzes the general situation and development status of the Pearl River night tour,and proposes five development strategies:the overall planning of culture and tourism integration,the deep integration of intangible cultural elements,the balance of commercial attributes and tourism attributes,the high integration of culture,business,tourism and education,and the creation of tourism atmosphere,in order to provide inspiration for the healthy,orderly and high-quality development of the Pearl River night tour.
文摘Tennessee Williams is the most famous Southern playwright in the history of 20th century American literature,and southern identity is a thread that runs throughout Williams’work.The Glass Menagerie is one of his highly representative dramatic works.The play tells the story of how an ordinary family in deep identity crisis escapes the harsh reality and cultural trauma during the Great Depression in the United States.Using trauma theory as a tool,this paper explores the complex relationship between the deep-seated causes of the tragedy of the two female characters in the play and the historical context through the traumatic events experienced by the characters in the play and the different attitudes they show in the face of trauma.Through this,the vulnerability and identity crisis of individuals during the period of social change and cultural breaks are analyzed.The purpose of the paper is to arouse human beings’thoughts on how to cope with cultural integration and foreign cultural invasion,and how to obtain salvation when they are amid an identity crisis.
