Long non-coding RNAs as promising targets for controlling disease vector mosquitoes

INSECT SCIENCE 2025年第1期32卷 24-41页

作者： Han, Yujiao pu, Qian Fan, Ting Wei, Tianqi Xu, Yankun Zhao, Lu Liu, Shiping Southwest Univ State Key Lab Resource Insects Chongqing 400716 Peoples R China

Hematophagous female mosquitoes are important vectors of numerous devastating human diseases, posing a major public health threat. Effective prevention and control of mosquito-borne diseases rely considerably on progress in understanding the molecular mechanisms of various life activities, and accordingly, the molecules that regulate the various life activities of mosquitoes are potential targets for implementing future vector control strategies. Many long non-coding RNAs (lncRNAs) have been identified in mosquitoes and significant progress has been made in determining their functions. Here, we present a comprehensive overview of the research advances on mosquito lncRNAs, including their molecular identification, function, and interaction with other non-coding RNAs, as well as their synergistic regulatory roles in mosquito life activities. We also highlight the potential roles of competitive endogenous RNAs in mosquito growth and development, as well as in insecticide resistance and virus-host interactions. Insights into the biological functions and mechanisms of lncRNAs in mosquito life activities, viral replication, pathogenesis, and transmission will contribute to the development of novel drugs and safe vaccines. Thousands of long non-coding RNA (lncRNAs) have been identified from different species of mosquitoes based on high-throughput transcriptome sequencing. Here we present a comprehensive overview of the research advances on mosquito lncRNAs, including their molecular identification, function, and interaction with other non-coding RNAs, as well as the potential mechanisms by which they regulate various mosquito life activities. image

Traumatic brain injury(TBI) is a significant globa public health challenge, with an estimated mortality rate of 13 per 100,000 people in China. Bedsides the immediate neurological consequences,^([1]) TBI is associated with longterm sequelae and an elevated risk of neurodegenerative conditions such as dementia, Parkinson's disease, and epilepsy. Moreover, TBI can induce systemic effects including acute gastrointestinal injury(AGI), contributing to poor patient outcomes.

High performance dielectric resonator(DR) bandpass filters(BPFs) are critical components in modern RF/microwave front-end systems due to their many distinctive advantages like low loss, small size, light weight, and temperature-stable properties. In recent years, the rapid development of various wireless communication techniques is demanding much more critical specifications for microwave BPFs with better performance but further reduced loss, size, and *** a prospective approach to meet these stringent requirements, BPFs using triple-mode DRs are attracting much attention from both academia and industry [1–5].

Power synchronization: taming massive diversified serverless functions under power constraints

引用

Science China(Information Sciences) 2025年第03期68卷 47-65页

作者： Du LIU Lu ZHANG Yechen XU Xinkai WANG Lingyu SUN Yifei pu Xiaofeng HOU Chao LI Minyi GUO Department of Computer Science and Engineering Shanghai Jiao Tong University AI Chip Center for Emerging Smart Systems The Hong Kong University of Science and Technology

Carbon neutrality has become an important design objective worldwide. However, the on-going shift to cloud-naive era does not necessarily mean energy efficiency. From the perspective of power management, co-hosted serverless functions are difficult to tame. They are lightweight, short-lived applications sensitive to power capping activities. In addition, they exhibit great individual and temporal variability, presenting idiosyncratic performance/power scaling goals that are often at odds with one another. To date, very few proposals exist in terms of tailored power management for serverless platforms. In this work, we introduce power synchronization, a novel yet generic mechanism for managing serverless functions in a power-efficient way. Our insight with power synchronization is that uniform application power behavior enables consistent and uncompromised function operation on shared host machines. We also propose PowerSync, a synchronization-based power management framework that ensures optimal efficiency based on a clear understanding of functions. Our evaluation shows that PowerSync can improve the energy efficiency of functions by up to 16% without performance loss compared to conventional power management strategies.
