文摘Liposarcoma is one of the most common soft tissue sarcomas,however,its occurrence rate is still rare compared to other cancers.Due to its rarity,in vitro experiments are an essential approach to elucidate liposarcoma pathobiology.Conventional cell culture-based research(2D cell culture)is still playing a pivotal role,while several shortcomings have been recently under discussion.In vivo,mouse models are usually adopted for pre-clinical analyses with expectations to overcome the issues of 2D cell culture.However,they do not fully recapitulate human dedifferentiated liposarcoma(DDLPS)characteristics.Therefore,three-dimensional(3D)culture systems have been the recent research focus in the cell biology field with the expectation to overcome at the same time the disadvantages of 2D cell culture and in vivo animal models and fill in the gap between them.Given the liposarcoma rarity,we believe that 3D cell culture techniques,including 3D cell cultures/co-cultures,and Patient-Derived tumor Organoids(PDOs),represent a promising approach to facilitate liposarcoma investigation and elucidate its molecular mechanisms and effective therapy development.In this review,we first provide a general overview of 3D cell cultures compared to 2D cell cultures.We then focus on one of the recent 3D cell culture applications,Patient-Derived Organoids(PDOs),summarizing and discussing several PDO methodologies.Finally,we discuss the current and future applications of PDOs to sarcoma,particularly in the field of liposarcoma.
文摘An earlier version of this paper has been presented online at the annual Conference of Canadian Sociological Association,during the Congress of Humanities and Social Sciences in Toronto in June 2025.It explores how rap music in Quebec,particularly through the work of the rap artist Webster and his collective Limoilou Starz(LS),serves as a tool for meaning-making,political expression,and resistance against racial profiling and police brutality experienced by Black youth in Quebec City.The study focuses on the song“SPVQ”(Service de police de la Ville de Québec)as a case study to analyze the encoding and reception of anti-racist messages within rap culture.Webster draws from a global tradition of socio-political rap-like that of African-American rappers KRS-One,LL Cool J,and Tupac-while anchoring his critique in the local realities of Limoilou,a marginalized,racially diverse district of Quebec City.Through a narrative,figurative,semantic,and ideological analysis of the song,the paper reveals how Webster articulates themes of police brutality,structural discrimination,economic marginalization,and resistance.The rapper’s message is both a form of testimony and a civic intervention.His broader activism is analyzed through ethnographic techniques-including participant observation and interviews during workshops,media appearances,and online campaigns.It translates these messages into tangible social practices.To explain the persistence of these injustices,the paper situates the issue within Quebec’s interculturalism framework,which ostensibly promotes dialogue and integration but often masks or even reinforces structural racism.This model maintains a symbolic majority/minority duality and conditions inclusion on conformity to a dominant White Francophone identity,thus rendering racialized youth as perpetual outsiders.

文摘Chengdu teahouses,as core public spaces in marketplace society,have undergone transformative reconstruction-from“containers of everyday life”to“containers of commercial traffic and digital flows”-during the process of modernization.Employing spatial archaeology as a methodology,combined with fieldwork and analysis of historical documents,this study systematically examines the diachronic evolution of architectural forms,functional orientations,and social networks within Chengdu teahouses.The study reveals the logic of spatial reconstruction under the interplay of multiple forces,including cultural heritage preservation,capital-driven development,and technological intervention.The findings identify three paradigms of spatial transformation in teahouses.First,heritage specimenization,which reinforces the continuity of collective memory through symbolic extraction but risks diminishing the vitality of everyday social interactions.Second,consumption upgrading,which caters to the demands of emerging groups through iterative business models yet necessitates vigilance against spatial differentiation eroding marketplace inclusivity.Third,digital parasitism,which expands communicative dimensions through technological empowerment but confronts the risk of flattening localized knowledge.These paradigms reflect both adaptive responses of traditional spaces to contemporary pressure and the tension of reconstruction imposed by instrumental rationality on marketplace networks.The study demonstrates that spatial transformation in Chengdu teahouses is not unidirectional alienation but rather a multifaceted configuration where the continuity of tradition coexists with innovative practices amid functional diversification.This research advocates for striking a balance between the preservation of traditional spaces and modern renewal and explores organic integration approaches for traditional and modern elements,thereby providing a theoretical framework and practical insights for the transformation of traditional public spaces.
文摘Introduction Diatoms,a diverse group of photosynthetic unicellular algae,have gained significant global attention due to their ecological importance and multifaceted applications in scientific research.Their ecological roles are critical,encompassing nutrient cycling,carbon sequestration,and primary productivity,which establish them as essential components of aquatic food webs.The remarkable species richness of diatoms underscores their evolutionary success and highlights their integral roles in both freshwater and marine ecosystems.In addition to their environmental significance,diatoms possess a rich biochemical profile comprising valuable compounds with immense potential for biotechnological applications.These applications span diverse fields,including biofuel production,pharmaceuticals,and wastewater remediation.Despite the vast diversity and biochemical richness of diatoms,laboratory cultivation and maintenance remain challenging.To address these challenges,two primary methodologies have been developed:xenic and axenic culture techniques.Xenic culture involves maintaining diatoms alongside associated microorganisms,thereby replicating natural conditions and preserving ecological interactions.In contrast,axenic culture techniques focus on isolating pure diatom strains by employing meticulous sterilization processes,enabling precise experimental manipulation and fundamental research.Understanding the significance of xenic and axenic cultivation methodologies is essential for unlocking the full potential of diatoms across diverse scientific domains.This review elaborates on the methodologies,scope,and applications of xenic and axenic culture techniques for diatoms.By examining the intricacies of these cultivation approaches,it seeks to provide insights into optimizing diatom culture practices,advancing research initiatives,and harnessing the biotechnological potential of these extraordinary microorganisms.
文摘Rice callus suspension culture(RCSC)has been shown to have anticancer activity based on cytotoxic activity on human colon and lung cancer cell lines.In the present study,the effect of RCSC on the expression of proteins in lung(A549)and colon(HT29)cancer cell lines was examined by using proteomics analysis.The protein-protein interaction study of differentially expressed proteins was done by using the Search Tool for the Retrieval of Interacting Genes(STRING),and the results showed that the proteins interacting with each other belong to different pathways.
