Restoration of kidney tubular epithelium following sublethal injury sequentially involves partial epithelial–mesenchymal transition(pEMT),proliferation,and further redifferentiation into specialized tubule epithelial cells(TECs).Because the immunosuppressant cyclosporine-A produces pEMT in TECs and inhibits the peptidyl-prolyl isomerase(PPIase)activity of cyclophilin(Cyp)proteins,we hypothesized that cyclophilins could regulate TEC *** we demonstrate that in cultured TECs,CypA silencing triggers loss of epithelial features and enhances transforming growth factorβ(TGFβ)-induced EMT in association with upregulation of epithelial repressors Slug and *** pro-epithelial action of CypA relies on its PPIase *** contrast,CypB emerges as an epithelial repressor,because CypB silencing promotes epithelial differentiation,prevents TGFβ-induced EMT,and induces tubular structures in 3D *** addition,in the kidneys of CypB knockout mice subjected to unilateral ureteral obstruction,inflammatory and pro-fibrotic events were *** silencing/knockout leads to Slug,but not Snail,*** support of Slug expression depends on its endoplasmic reticulum location,where it interacts with calreticulin,a calcium-buffering chaperone related to Slug *** CypB silencing reduces ionomycin-induced calcium release and Slug upregulation,we suggest that Slug expression may rely on CypB modulation of calreticulin-dependent calcium *** conclusion,this work uncovers new roles for CypA and CypB in modulating TEC plasticity and identifies CypB as a druggable target potentially relevant in promoting kidney repair.

On the Range of Action of Adult Culex pipiens s.l.

Mosquitoes are an interesting topic due to their medical importance, as they play an active role in the transmission of many pathogens and parasites, acting as vectors for various pathologies that are deadly to humans, such as dengue, yellow fever, chikungunya, West Nile virus, encephalitis and malaria, among many others that are less common. In terms of morbidity and mortality caused by vector-borne diseases, mosquitoes are the most dangerous animals for humanity and, although they also play a role in the ecosystem as a food source for other organisms, their importance for public health cannot be overlooked. As highly efficient vectors, they put more than three billion people at risk, mainly in tropical and subtropical regions as well as in Europe, since heat waves and flooding are becoming more frequent and severe, and summers are getting longer and warmer, accelerating mosquito development, biting rates, and the incubation of the pathogens within their bodies. Female mosquitoes bite to acquire proteins for the development of their ovaries and eggs and, in the process, acquire pathogens and/or parasites from one vertebrate host and transmit them to another, usually after a short period of replication. Three of their four life stages are lived in still freshwater, so it is crucial to understand their range of action when they reach adulthood and leave the water, in order to plan and implement local prevention measures. A set of georeferenced abundance data collected in mainland Portugal over seven years was linked to cartographed water bodies in a geographic information system to estimate the distances at which Culex pipiens s.l. had a significant presence, with criteria based on the size of the catches. The result allows for an estimate of the fly range of those mosquitoes, which can be used to focus countermeasures.

针对几何失谐整体叶盘结构动力学特性评估问题，开展基于先进光学几何测量技术的高保真整体叶盘数字孪生建模、高性能结构动力学仿真分析和试验验证研究。首先，采用三维结构蓝光扫描系统测取叶片几何型面的高分辨率点云模型，将其直接关联至谐调整体叶盘设计有限元模型，通过网格自适应变形技术实现高保真整体叶盘数字孪生模型的高效构建。其次，整体叶盘数字孪生高性能动力学仿真分析方法立足于大规模几何失谐整体叶盘模型的新型动力学减缩技术，其核心是利用各几何失谐单扇区结构的循环对称模态振型来构建数字孪生整盘模型的减缩模态基底，以减少计算内存和时长的消耗。试验结果表明，针对实体整体叶盘模拟件结构构建的高保真数字孪生模型既能有效地捕获叶片微小几何失谐对其“扇区”频率和振型的影响，也能较为准确地预测旋转整体叶盘在发动机阶次激励作用下的失谐振动响应特性。
