Introduction: The DRC had planned 23 mass distribution campaigns distribution of long-lasting insecticidal nets (LLIN) for the years 2018-2020, the implementation of which spanned from 2018 to July 2021. This article reviews the campaign’s planning process, the results, challenges, and lessons learned. Methods: A descriptive method was used to postpone the planning and implementation process according to the National Malaria Control Program (NMCP) standards adapted to the COVID-19 context. The changes and adaptations implemented as well as the challenges encountered are described. Results: Between January 2018 to June 2021, 23 LLIN mass distribution campaigns were organized in the DRC with the financial support of The Global Fund to Fight against Tuberculosis, AIDS and Malaria (GFTAM) and Against Malaria Foundation (AMF) allowing the distribution of 55,273,473 LLINs to 19,048,372 households at risk of malaria transmission with an average of 2.9 LLINs per household. The enumerated population (111,081,191) exceeded 7% of the micro plans projected population (102,790,391) while the number of households enumerated (19,311,629) was 3% lower compared to the micro planning projection households (19,862,417). Compared to a reported household coverage of 96% of households achieved over the expected households, the independent monitoring carried out revealed 91% of households served in the intervention areas. The main reasons for not reaching households mentioned by the respondents were absence at the time of distribution (26%) followed by the loss of vouchers (16%). Several communication channels were used among which, community workers were the most frequently mentioned (63.1%), followed by radios (18.5%) and churches (12.4%). Conclusion: Good planning, effective coordination of stakeholders, and revision of the implementing campaigns methods following the COVID-19 were factors in the success of this campaign.

Laboratorial and epidemiological research has established a relationship between paraquat（PQ） exposure and a risk for Parkinson′s disease. Previously, we have investigated the effects of nuclear factor erythroid 2 related factor 2（Nrf2） and microRNAs in PQ-induced neurotoxicity, addressing the function of miR-380-3p, a microRNA dysregulated by PQ, as well as Nrf2 deficiency. Nrf2 is known to mediate the expression of a variety of genes, including non-coding genes. By chromatin immunoprecipitation, we identified the relationship between Nrf2 and miR-380-3p in transcriptional regulation. qRT-PCR, western-blots, and dual-luciferase reporter gene assay showed that miR-380-3p blocked the translation of the transcription factor Sp3 in the absence of degradation of Sp3 mRNA. Results based on cell counting analysis, annexin v-fluorescein isothiocyanate/propidium iodide doublestaining assay and propidium iodide staining showed that overexpression of miR-380-3p inhibited cell proliferation, increased the apoptotic rate, induced cell cycle arrest and intensified the toxicity of PQ in mouse neuroblastoma（N2 a） cells. Knockdown of Sp3 inhibited cell proliferation and eclipsed the alterations induced by miR-380-3p in cell proliferation. Two mediators of apoptosis and cell cycle identified in previous studies as Sp3-regulated, namely cyclin-dependent kinase inhibitor 1（p21） and calmodulin（CaM）, were dysregulated by PQ, but not Sp3 deficiency. In conclusion, Nrf2-regulated miR-380-3p inhibited cell proliferation and enhanced the PQ-induced toxicity in N2a cells potentially by blocking the translation Sp3 mRNA. We conclude that CaM and p21 were involved in PQ-induced toxicity.

人类行为引起的空前的全球变化挑战着社会支撑我们这颗行星保持自身优点的能力。这就要求对变化进行主动的管理以培养地球的恢复力——维持在变化的情况下对社会很重要的一些属性,和适应性——发展新的社会生态构造以便在新的条件下有效地发挥作用。北极的广大地区仍然完整地保留着原型的生态及社会过程及反馈,这为我们为变化预先做出计划提供了可能是最后一个实验的机会。如果该策略的可行性在北极可以被证实,我们对于变化的动态所得到的进一步的理解就可以实施到那些被人类较大地改变了的地区中。现在执行管理北极变化的政策的条件可能很理想,因为近来的研究提供了极其重要的科学知识,合适的国际机制也已各就各位,而且,如果北极地区的国家选择这样做的话,他们具备实行必要改变的财力。
