Edible plant derived exosome-like nanoparticles(ELNs)have been shown to have multiple nutraceutical functions.However,the diversity of plant materials makes the plant derived ELN study challenging.More efforts are still needed to explore the feasible isolation methods of edible plant derived ELNs and the possible roles of food-derived ELNs in improving human health.In this study,a size exclusion chromatography based method was compared with the traditional ultracentrifugation method to isolate blueberry derived ELNs(B-ELNs),and the miRNA profile of B-ELNs was analyzed by high-throughput sequencing.A total of 36 miRNAs were found to be enriched in B-ELNs compared with berry tissue,and their potential cross-kingdom human gene targets were further predicted.Results showed that size exclusion chromatography was effective for B-ELN isolation.The most abundant miRNAs in B-ELNs mainly belonged to the miR166 family and miR396 family.Target gene prediction indicated that B-ELNs could potentially regulate pathways related to the human digestive system,immune system and infectious diseases. 展开更多

Interference management is one of the most important issues in the device-to-device(D2D)-enabled heterogeneous cellular networks(HetCNets)due to the coexistence of massive cellular and D2D devices in which D2D devices reuse the cellular spectrum.To alleviate the interference,an efficient interference management way is to set exclusion zones around the cellular receivers.In this paper,we adopt a stochastic geometry approach to analyze the outage probabilities of cellular and D2D users in the D2D-enabled HetCNets.The main difficulties contain three aspects:1)how to model the location randomness of base stations,cellular and D2D users in practical networks;2)how to capture the randomness and interrelation of cellular and D2D transmissions due to the existence of random exclusion zones;3)how to characterize the different types of interference and their impacts on the outage probabilities of cellular and D2D users.We then run extensive Monte-Carlo simulations which manifest that our theoretical model is very accurate. 展开更多

This paper presents the results of a research project on the intercultural climate in schools and the academic success of immigrant students in Quebec.The intercultural climate in eight secondary public schools is documented from the standpoint of various school and community stakeholders,students,and parents.More specifically,the paper focuses on the commitment to promoting cultural equity,which is identified through interviews with the targeted stakeholders on exclusionary practices and processes and the practices implemented to counter them.The results identify five areas of vulnerability among certain minoritized groups of students:the transition from welcoming to regular classes for those students learning French,evaluation and support for those experiencing learning or behavioral difficulties,the referral of these students to adult education programs or work-oriented training programs,their participation in extracurricular activities,and their access to special school projects.Nonetheless,some schools do report the introduction of many equity practices in response to the exclusionary ones.However,these initiatives are mostly occasional and voluntary and pertain to interactions between individuals.These findings call for a discussion on the importance of systemic and concerted initiatives towards achieving equity. 展开更多

This paper reveals that the implementation of inclusive education is an unfinished challenge,both within the system and for individual self-improvement.This process of changing practices,by continually questioning the school’s responsibility for the(re)production of inequalities,exclusion,and unequal social relations,is riddled with obstacles,unpredictable situations,and strong emotions.In particular,the researchers point out that many systemic mechanisms of school culture contribute to replicating and reifying hierarchical school experiences and exacerbating processes of institutional discrimination against immigrant backgrounds and/or racialized students.The empirical research presented also highlights the school staff’s deficit thinking toward immigrant students and their parents.The results show that staff tend to use linguistic and cultural gaps between students and the school system to explain academic failure.Be that as it may,the researchers as well as the school actors and students interviewed in this paper suggest multiple ways to improve inclusion in the school context,stressing the importance of giving voice to the various actors in order to move toward institutional transformation. 展开更多

In connection with the historical context of social segregation and the assimilative aim of formal education imposed on them,the Indigenous Peoples of Québec have long been excluded from higher education.Today,even if their graduation rates are increasing,a persistent gap with the non-Indigenous population is maintained.The data in this article are drawn from 23 interviews with students and university graduates of the First Nations of Québec,as part of a thesis in educational sciences.Our paper analyzes how these students manage to combine the contributions of Indigenous education with those of Western education by developing paths that are part of the decolonization movement of education.Their relationship to Indigenous identity and cultures clearly influences their educational background and is analyzed taking into account power relations with the dominant culture.Our paper emphasizes more particularly the relationship to studies,the adaptation to the student profession,and the balance between studies,work,and family among Indigenous students,in a context of transition from university to multiversity which contributed to the increase of Indigenous university attendance. 展开更多

The recognition of the positive value of student diversity and their right to full participation are key aspects of inclusion as a means of managing heterogeneity of the school population from an equality perspective.As the school cannot welcome the diversity of children without including their families,the same logic needs to apply to the relationship between the school and parents,particularly in the current environment where the school-family partnership appears as a privileged institutional leverage in the fight against inequalities at school.Based on an ethnographical study exploring how the relationship between the school and the families builds up in a Swiss school located in a context of strong cultural diversity,this paper interrogates how the school norm can be the main limitation to the inclusion of students and parents who are unfamiliar with the school.Derived from field observations and interviews,our results show how the teachers tend to approach their relationship with new students and their parents from the standpoint of narrowly defined expected models,leading them to engage in a vain attempt to conform the students and parents when they deviate from these models.The possibility of entering the school system for students and parents unfamiliar with school is hindered by the exclusive and excluding normativity on which the models of the child and the parent expected by the teachers are grounded.Based on these observations,we discuss how an inclusive approach seems to us to require in the first place a necessary process of decentering from the school and teachers,as a condition for recognition of the actual child and parent. 展开更多

The school placement processes of students from immigrant backgrounds considered to be in“difficulty”is an international concern at the intersection of works relating to special education and those concerning the school experiences of students from immigrant backgrounds or racialized groups.The research problem of this article concerns the identification of these students as disabled or as having adjustment or learning difficulties.From a perspective anchored in Disability Critical Race Studies,this ethnographic study documents different interpretations of perceived difficulties made by school actors with regard to seven primary school students from immigrant backgrounds.Five interpretation types are presented:(1)medicalization by dismissal of cultural markers,(2)medicalization by professional constraint,(3)medicalization by cultural deficit,(4)precautionary wait,and(5)cultural differentialism.Our results help to shed light on the special education overrepresentation phenomenon regarding these students and to understand how ableism and(neo)racism contribute to it. 展开更多

In recent years,Francophone schools in Alberta,a province in western Canada,have seen significant ethnocultural diversification of their school population,thus reflecting recent migratory changes in Canada.The population of a Francophone school board located in an agglomeration of Alberta reflects these new migratory trends.A partial ethnodemographic portrait carried out in 2003 in six of its schools indicates that 50%of the pupils come from an immigrant background and come from 23 different countries;mostly from sub-Saharan African countries.This demographic reality,confirmed more than a decade later,represents a major structural change for Francophone schools.In Alberta,as in other Canadian provinces,inclusion is at the heart of discourse and educational practices.With a transformative aim,it intends to promote ethnocultural diversity in the classroom and equal opportunities through school equity practices.This article focuses on the settlement workers in schools responsible for bridging family,community,and school cultures.The analysis of the interviews of the four workers sheds light on and questions both the institutional practices and the personal strategies put in place to face the challenges encountered in this tripartite collaboration. 展开更多

Grazing exclusion is one of the primary management practices used to restore degraded grasslands on the Tibetan Plateau.However,to date,the effects of long-term grazing exclusion measures on the process of restoring degraded alpine meadows have not been evaluated.In this study,moderately degraded plots,in which the vegetation coverage was approximately 65%and the dominant plant species was Potentilla anserina L,with grazing exclusion for 2 to 23 years,were selected in alpine meadows of Haibei in Qinghai-Tibet Plateau.Plant coverage,plant height,biomass,soil bulk density,saturated water content,soil organic carbon(SOC)and total nitrogen(TN)were evaluated.The results were as follows:(1)With aboveground biomass and total saturated water content at 0-40 cm depth,the average SOC and TN contents in moderately degraded alpine meadows increased as a power function,and the plant height increased as a log function.(2)The average soil bulk density at 0-40 cm depth first decreased and then increased with increasing grazing exclusion duration,and the minimum value of 0.90 g·cm^(-3) was reached at 15.23 years.The plant coverage,total belowground biomass at 0-40 cm depth,total aboveground and belowground biomass first increased and then decreased,their maximum values(80.49%,2452.92g·m^(-2),2891.06 g·m^(-2))were reached at 9.41,9.46 and 10.25 years,respectively.Long-term grazing exclusion is apparently harmful for the sustainable restoration of degraded alpine meadows.The optimal duration of grazing exclusion for the restoration of moderately degraded alpine meadows was 10 years.This research suggests that moderate disturbance should be allowed in moderately degraded alpine meadows after 10years of grazing exclusion. 展开更多

BACKGROUND Although the availability of related living donors(LDs)provides a better chance for receiving kidney transplantation(KT),the evaluation protocols for LD selection remain a safeguard for the LD’s safety.These protocols are variable from one center to another,resulting in variable rates of decline of the potential LDs(PLDs).The decline of willing PLDs may occur at any stage of evaluation,starting from the initial contact and counseling to the day of operation.AIM To identify the causes of the decline of PLDs,the predictors of PLD candidacy,and the effect on achieving LDKT.METHODS A retrospective study was performed on the willing PLDs who attended our outpatient clinic for kidney donation to their related potential recipients between October 2015 and December 2022.The variables influencing their candidacy rate and the fate of their potential recipients were studied.Two groups of PLDs were compared:Candidate PLDs after a completed evaluation vs non-candidate PLDs with a complete or incomplete evaluation.A multivariate logistic regression was performed to assess the factors contributing to the achievement of PLD candidacy.RESULTS Of 321 willing PLDs,257 PLDs(80.1%)accessed the evaluation to variable extents for 212 potential recipients,with a mean age(range)of 40.5±10.4(18-65)years,including 169 females(65.8%).The remaining 64 PLDs(19.9%)did not access the evaluation.Only 58 PLDs(18.1%)succeeded in donating,but 199 PDLs(62.0%)were declined;exclusion occurred in 144 PLDs(56.0%)for immunological causes(37.5%),medical causes(54.9%),combined causes(9.7%),and financial causes(2.1%).Regression and release occurred in 55 PLDs(17.1%).The potential recipients with candidate PLDs were not significantly different from those with non-candidate PLDs,except in age(P=0.041),rates of completed evaluation,and exclusion of PLDs(P<0.001).There were no factors that independently influenced the rate of PLD candidacy.Most patients who failed to have KT after the decline of their PLDs remained on hemodialysis for 6 mo to 6 years.CONCLUSION The rate of decline of willing related PLDs was high due to medical or immunological contraindications,release,or regression of PLDs.It reduced the chances of high percentages of potential recipients in LDKT. 展开更多

Consider a generalized model of the facilitated exclusion process, which is a onedimensional exclusion process with a dynamical constraint that prevents the particle at site x from jumping to x+1 (or x-1) if the sites x-1, x-2 (or x+1, x+2) are empty. It is nongradient and lacks invariant measures of product form. The purpose of this paper is to identify the invariant measures and to show that they satisfy both exponential decay of correlations and equivalence of ensembles. These properties will play a pivotal role in deriving the hydrodynamic limit. 展开更多

This paper studies two-lane asymmetric simple exclusion processes(ASEPs)with an intersection.In the upstream segments of the intersection,one particle can move to the next site with rate 1 if the site is empty,and the other particle can move forward with rate p in the sites of downstream segments.The parameter p can represent the rate of slowing of motion,and the parameter is introduced to investigate spontaneous symmetry breaking(SSB)phenomenon.Extensive Monte Carlo simulations are carried out.It is shown that three symmetric phases exist and the SSB does not exist in the system.Simple mean field approach in which correlation of sites is ignored is firstly adopted to analyze the system,and the system is divided into four independent segments.It is found that the analytical results deviate from the simulation ones,especially when p is small.In addition,the inexsitence of SSB can only be explained qualitatively.Motivated by this,we carry out the cluster mean field analysis in which correlation of five sites is considered.It is shown that densities of the two upstream segments are equal,which demonstrates that the SSB does not exist.It is also shown that,as expected,the cluster mean field analysis performs much better than the simple mean field analysis. 展开更多

We investigate the information exclusion principle for multiple measurements with assistance of multiple quantum memories that are well bounded by the upper and lower bounds.The lower bound depends on the observables'complementarity and the complementarity of uncertainty whilst the upper bound includes the complementarity of the observables,quantum discord,and quantum condition entropy.In quantum measurement processing,there exists a relationship between the complementarity of uncertainty and the complementarity of information.In addition,based on the information exclusion principle the complementarity of uncertainty and the shareability of quantum discord can exist as an essential factor to enhance the bounds of each other in the presence of quantum memory. 展开更多

BACKGROUND: Significant hemorrhage together with blood transfusion increases postoperative morbidity and mortality of hepatic resection. Hepatic vascular occlusion is effective in minimizing bleeding during hepatic parenchymal transection. This article aimed to review the current role and status of various techniques of hepatic vascular occlusion during hepatic resection. DATA SOURCES: The relevant manuscripts were identified by searching MEDLINE, and PubMed for articles published between January 1980 and April 2010 using the keywords 'vascular control', 'vascular clamping', 'vascular exclusion' and 'hepatectomy'. Additional papers were identified by a manual search of the references from the key articles. RESULTS: One randomized controlled trial (RCT) and 5 RCTs showed intermittent Pringle maneuver and ischemic preconditioning followed by continuous Pringle maneuver were superior to continuous Pringle maneuver alone, respectively. Two RCTs compared the outcomes of hepatectomy with and without intermittent Pringle maneuver. One showed Pringle maneuver to be beneficial, while the other failed to show any benefit. One RCT showed that ischemic preconditioning had significantly less blood loss than using intermittent Pringle maneuver. Four RCTs evaluated the use of hemihepatic vascular occlusion. One RCT showed it had significantly less blood loss than Pringle maneuver, while the other 3 showed no significant difference. Only 1 RCT showed it had significantly less liver ischemic injury. No RCT had been carried out to assess segmental vascular occlusion. Two RCTs compared the outcomes of total hepatic vascular exclusion (THVE) and Pringle maneuver. One RCT showed THVE resulted in similar blood loss, but a higher postoperative complication. The other RCT showed less blood loss using THVE but the postoperative complication rate was similar. Both studies showed similar degree of liver ischemic injury. Only one RCT showed that selective hepatic vascular exclusion (SHVE) had less blood loss and liver ischemic injury than Pringle maneuver. CONCLUSION: Due to the great variations in these studies, it is difficult to draw a definitive conclusion on the best technique of hepatic vascular control. 展开更多

Many studies have looked at connections between diet,etiology,signs and symptoms associated with inflammatory bowel disease(IBD).Although these connections are apparent to clinicians,they are difficult to prove qualitatively or quantitatively.Enteral feeding and polymeric diets are equally effective at bringing about remission in Crohn's disease(CD).Parenteral feeding is also effective,although none of these methods is as effective as corticosteroid therapy.However,enteral feeding is preferred in the pediatric population because linear growth is more adequately maintained via this route.Exclusion diets in patients brought into remission using an elemental diet have been shown to maintain remission for longer periods.Studies that aim to isolate culpable food groups have shown that individuals react differently on exposure to or exclusion of various foods.The commonly identifi ed food sensitivities are cereals,milk,eggs,vegetables and citrus fruits.Studies that have looked at gut mucosal antigen behavior have shown higher rectal blood flow,in response to specifi c food antigens,in those with CD over healthy subjects.Exclusion of sugar shows little evidence of amelioration in CD.Omega 3 fatty acids show promise in the treatment of IBD but await larger randomized controlled trials.Patients frequently notice that specifi c foods cause aggravation of their symptoms.Whilst it has been diffi cult to pinpoint specifi c foods,with advances in the laboratory tests and food supplements available,the aim is to prolong remission in these patients using dietary measures,and reduce the need for pharmacotherapy and surgical intervention. 展开更多

BACKGROUND: Hepatic resection is the main treatment modality for hepatic tumors. Advances in diagnostic technique, preoperative preparation, surgical technique, and postoperative management increased the success rate. The present study aimed to evaluate hepatectomy and resection of inferior vena cava tumor thrombus (IVCTT) in patients with hepatocellular carcinoma, and the relationship between IVCTT classification and selection of surgical technique. METHODS: We retrospectively reviewed 13 patients with hepatocellular carcinoma who had undergone hepatectomy with IVCTT resection between May 1997 and August 2009. Age, gender, diagnosis, findings of physical examination, results of preoperative laboratory investigations, radiological examination, criteria for resection, postoperative pathological results, incisions, operative technique, intraoperative transfusion, drains, and intraoperative and postoperative complications were evaluated for all patients. RESULTS: Type Ⅰ IVCTT (10 patients) was posterior to the liver and below the diaphragm; type Ⅱ IVCTT (2 patients) was above the diaphragm but still outside the atrium; and type Ⅲ IVCTT (1 patient) was above the diaphragm and in the right atrium. Type Ⅰ was treated by radical hepatectomy and removal of IVCTT with total hepatic vascular exclusion. Type Ⅱ was treated by radical hepatectomy and removal of IVCTT by incision of the diaphragm. Type Ⅲ was treated by hepatectomy and resection of the thrombus from the right atrium under cardiopulmonary bypass. There were no surgical complications and one patient has been survived for 4 years with cancer-free status. The median survival time was 18.2 months, and the 1-and 2-year survival rates were 53.8% and 15.4%, respectively. CONCLUSION: Surgical treatment is safe and feasible for treatment of IVCTT in patients with hepatocellular carcinoma, and surgical resectability can be judged according to the classification of tumor thrombus. 展开更多
