Introduction: Seasonal malaria chemoprevention (SMC) was adopted in 2019 in two health zones in Benin where malaria transmission is very high. Positive results led to the extension of the intervention to other zones with additional financial support. Annual SMC campaigns from 2021 to 2023 were carried out in all six health zones in the Atacora and Alibori departments. In five years of implementation, various approaches have been developed on the basis of a communication plan facilitating buy-in and acceptance by all stakeholders. The aim of this study was to assess the effective coverage and acceptance of the SMC by their beneficiary populations in 2023. Methods: It was a cross-sectional study with an analytical focus. Data collection took place from November 30 to December 13, 2023. The study population consisted of children under 5 years of age residing in the departments of Atacora and Alibori in northern Benin. A total of 3573 children under 5 years of age were included in the study, and their parents or guardians were interviewed. Results: During the 2023 campaign, 87.7% of targets were reached by SMC administration and 100.00% of children had received at least one dose of SMC by the fourth visit. Effective therapeutic coverage of SMC was 70.55%, with 99.60% in BNK, 69.40% in KGS, 16.20% in MK, 56.10% in 2KP, 92.40% in NBT and 89.60% in TMC. This coverage was statistically related to child and respondent ages (p Conclusion: SMC is a strategy accepted by the population, and the main reasons for non-participation in SMC were dominated by the absence of mothers or babysitters when the agents visited.

The levels and partitioning of genetic diversity and inbreeding depression were investigated in Tupistra pingbianensis,a narrow endemic of southeast Yunnan,China,characterized by a naturally fragmented distribution due to extreme specialization on a rare habitat *** genetic diversity and patterns of genetic variation within and among 11 populations were analyzed using amplified fragment length polymorphism markers with 97 individuals across its whole geographical *** levels of genetic variation were revealed both at the species level(P 99 = 96.012%;H t = 0.302) and at the population level(P 99 = 51.41%;H s = 0.224).Strong genetic differentiation among populations was also detected(F ST = 0.2961;θⅡ = 0.281),which corresponded to results reported for typical animal-pollinated,mixed selfing,and outcrossing plant *** result was consistent with mating patterns detected by our pollination *** indirect estimate of gene flow based on θⅡ was low(N m = 0.64).Special habitat and its life history traits might play an important role in shaping the genetic diversity and the genetic structure of this species.A pollination experiment also failed to detect significant inbreeding depression upon F 1 fruit set,seed weight,and germinate rate *** a naturally rare species,*** is not seriously genetically impoverished and likely to have adapted to tolerating a high level of inbreeding early in its history,we propose this species need only periodic monitoring to ensure their continued persistence,but not intervention to remain viable.

Large scale manufacture of magnetic polymer particles using membranes and microfluidic devices

引用

China Particuology 2007年第1期5卷 26-42页

作者： richard A. Williams Institute of Particle Science and Engineering School of Process Environmental and Materials Engineering University of Leeds Clarendon Road Leeds LS2 9JT United Kingdom

Magnetic polymer particles have found applications in diverse areas such as biomedical treatments, diagnosis and separation technology. These applications require the particles to have controlled sizes and narrow size distributions to gain better control and reproducibility in use. This paper reviews recent developments in the preparation of magnetic polymer particles at nano- and micro-scales by encapsulating magnetic components with dissolved or in situ formed polymers. Particle manufacture using emulsification and embedment methods produces magnetic polymer particles at micro-scale dimensions. However, the production of particles in this range using conventional emulsification methods affords very limited control over particle sizes and polydispersity. We report on alternative routes using membrane and microfluidics emulsification techniques, which have a capability to produce monodisperse emulsions and polymer microspheres （with coefficients of variation of less than 10%） in the range from submicrometer to a few 100 μm. The performance of these manufacturing methods is assessed with a view to future applications.

Nasopharyngeal liposarcoma is an extremely rare clinical entity. Less than ten cases have been reported in the literature. It mainly occurs in humans. The non-specificity of the clinical and radiological signs explains the difficulty of the diagnosis confirmed by anatomopathological and immunohistochemical examinations. Its pathogenesis remains obscure and often correlates with genetic abnormalities. Pleomorphic liposarcoma is its rarest subtype, remarkable for its aggressiveness and rapidity of growth. Complete surgical excision remains the treatment of choice. We report a case of liposarcoma whose diagnosis was made during histological examination coupled with immunohistochemistry. .

Digital Communications and Networks 2022年第1期8卷 44-50页

作者： Lijun Dong richard Li Futurewei Technologies Inc. 2330 Central ExpresswaySanta Clara95050USA

Network processing in the current Internet is at the entirety of the data packet,which is problematic when encountering network *** newly proposed Internet service named Qualitative Communication changes the network processing paradigm to an even finer granularity,namely chunk level,which obsoletes many existing networking policies and schemes,especially the caching algorithms and cache replacement policies that have been extensively explored in Web Caching,Content Delivery Networks(CDN)or Information-Centric Networks(ICN).This paper outlines all the new factors that are brought by random linear network coding-based Qualitative Communication and proves the importance and necessity of considering them.A novel metric is proposed by taking these new factors into *** optimization problem is formulated to maximize the metric value of all retained chunks in the local storage of network nodes under the constraint of storage limit.A cache replacement scheme that obtains the optimal result in a recursive manner is proposed *** the help of the introduced intelligent cache replacement algorithm,the performance evaluations show remarkably reduced end-to-end latency compared to the existing schemes in various network scenarios.
