Until recently, the functions of border-associated macrophages have been poorly understood and largely overlooked. However, a recent study reported that border-associated macrophages participate in stroke-induced inflammation, although many details and the underlying mechanisms remain unclear. In this study, we performed a comprehensive single-cell analysis of mouse border-associated macrophages using sequencing data obtained from the Gene Expression Omnibus(GEO) database(GSE174574 and GSE225948). Differentially expressed genes were identified, and enrichment analysis was performed to identify the transcription profile of border-associated macrophages. CellChat analysis was conducted to determine the cell communication network of border-associated macrophages. Transcription factors were predicted using the ‘pySCENIC' tool. We found that, in response to hypoxia, borderassociated macrophages underwent dynamic transcriptional changes and participated in the regulation of inflammatory-related pathways. Notably, the tumor necrosis factor pathway was activated by border-associated macrophages following ischemic stroke. The pySCENIC analysis indicated that the activity of signal transducer and activator of transcription 3(Stat3) was obviously upregulated in stroke, suggesting that Stat3 inhibition may be a promising strategy for treating border-associated macrophages-induced neuroinflammation. Finally, we constructed an animal model to investigate the effects of border-associated macrophages depletion following a stroke. Treatment with liposomes containing clodronate significantly reduced infarct volume in the animals and improved neurological scores compared with untreated animals. Taken together, our results demonstrate comprehensive changes in border-associated macrophages following a stroke, providing a theoretical basis for targeting border-associated macrophages-induced neuroinflammation in stroke treatment.展开更多

Numerous problems and deficiencies identified through different projects. The studies and planning documents are evident for environmental media and areas. Such as lack of regional integrated systems for municipal solid waste management. The system for special waste types management, including hazardous waste, insufficient coverage of populated places and municipalities by wastewater collection and treatment systems （especially in agglomerations above 10,000 populations）. The need to establish integrated river basin management is in accordance with the new law on waters, air pollution with different intensity in different parts of the country.

The procedure is described, as well as the legal matters that this issue generates. Gestational carriers appear as an alternative for couples who want to have a child but they are not able to conceive because of infertility issues and do not want to go through an adoption process. Therefore, they adhere to surrogacy as an alternative of assisted human reproduction;a procedure that in Colombia faces serious legal gaps and causes ethical dilemmas in the collective imagery. These situations suggest an open discussion through a dialectics between the scientific progress advances, the lack of legal regulation and the constants against ethical positions that the surrogacy procedure causes in Colombia and other parts of the world.展开更多

文摘Purpose:This research proposes a patent portfolio analysis model based on the legal status information to chart out a competitive landscape in a particular field,enabling organizations to position themselves within the overall technology landscape.Design/methodology/approach:Three indicators were selected for the proposed model:Patent grant rate,valid patents rate and patent maintenance period.The model uses legal status information to perform a qualitative evaluation of relative values of the individual patents,countries or regions’ technological capabilities and competitiveness of patent applicants.The results are visualized by a four-quadrant bubble chart To test the effectiveness of the model,it is used to present a competitive landscape in the lithium ion battery field.Findings:The model can be used to evaluate the values of the individual patents,highlight countries or regions’ positions in the field,and rank the competitiveness of patent applicants in the field.Research limitations:The model currently takes into consideration only three legal status indicators.It is actually feasible to introduce more indicators such as the reason for invalid patents and the distribution of patent maintenance time and associate them with those in the proposed model.Practical implications:Analysis of legal status information in combination of patent application information can help an organization to spot gaps in its patent claim coverage,as well as evaluate patent quality and maintenance situation of its granted patents.The study results can be used to support technology assessment,technology innovation and intellectual property management.Originality/value:Prior studies attempted to assess patent quality or competitiveness by using either single patent legal status indicator or comparative analysis of the impacts of each indicator.However,they are insufficient in presenting the combined effects of the evaluation indicators.Using our model,it appears possible to get a more complete and objective picture of the current competitive situation.
文摘Contrary to the approach in judicial practice,Paragraph 1,Article 153,of the Civil Code of the People’s Republic of China,as a rule of invalidity for violating mandatory provisions,does not adopt a dichotomy towards mandatory provisions with effectiveness and administrative characteristics,yet it maintains the legislative philosophy of differentiation.It leaves unspecified whether mandatory provisions that do not explicitly render a juristic act invalid impact the act’s validity,entrusting this determination to the discretion of judges on a case-by-case basis.When judges,under the authority of Paragraph 1,Article 153 of the Civil Code,explore the normative intent of mandatory provisions to assess their effect on the validity of juristic acts,they should engage in legal policy analysis centered on consequence-based argumentation to overcome the limitations of norm typological analysis.This analysis employs a reasoning model predicated on the normative purpose,utilizing a consequencefocused interpretative approach for formulating and arguing propositions of rules applicable to pending cases,thereby arriving at case-specific conclusions.Since the invalidation of juristic acts serves as an auxiliary regulatory tool for the state economy and society,a consequence-oriented interpretation needs to be based on the idea of mutual instrumentalization of public and private laws.This entails predicting the outcomes of negating the validity of a juristic act in industrial regulatory scenarios and assessing these outcomes within the framework of public and private regulatory instruments.
文摘Environmental problems in the Republic of Macedonia and Albania are similar in other countries in the region. Numerous problems and deficiencies identified through different projects. The studies and planning documents are evident for environmental media and areas. Such as lack of regional integrated systems for municipal solid waste management. The system for special waste types management, including hazardous waste, insufficient coverage of populated places and municipalities by wastewater collection and treatment systems （especially in agglomerations above 10,000 populations）. The need to establish integrated river basin management is in accordance with the new law on waters, air pollution with different intensity in different parts of the country. This paper presents the imperative reforms to protect the natural resources and biodiversity in the countries.
文摘Different from precision,fuzziness owns some special features.This paper tries to do a preliminary analysis of previous research on fuzziness and fuzzy expressions in legal texts.
文摘This text sets out the different arguments regarding surrogacy as a reproductive medicine tech-nique in Colombia. The procedure is described, as well as the legal matters that this issue generates. Gestational carriers appear as an alternative for couples who want to have a child but they are not able to conceive because of infertility issues and do not want to go through an adoption process. Therefore, they adhere to surrogacy as an alternative of assisted human reproduction;a procedure that in Colombia faces serious legal gaps and causes ethical dilemmas in the collective imagery. These situations suggest an open discussion through a dialectics between the scientific progress advances, the lack of legal regulation and the constants against ethical positions that the surrogacy procedure causes in Colombia and other parts of the world.
