Role of the globus pallidus in motor and non-motor symptoms of Parkinson's disease

The globus pallidus plays a pivotal role in the basal ganglia circuit. Parkinson's disease is characterized by degeneration of dopamine-producing cells in the substantia nigra, which leads to dopamine deficiency in the brain that subsequently manifests as various motor and non-motor symptoms. This review aims to summarize the involvement of the globus pallidus in both motor and non-motor manifestations of Parkinson's disease. The firing activities of parvalbumin neurons in the medial globus pallidus, including both the firing rate and pattern, exhibit strong correlations with the bradykinesia and rigidity associated with Parkinson's disease. Increased beta oscillations, which are highly correlated with bradykinesia and rigidity, are regulated by the lateral globus pallidus. Furthermore,bradykinesia and rigidity are strongly linked to the loss of dopaminergic projections within the cortical-basal ganglia-thalamocortical loop. Resting tremors are attributed to the transmission of pathological signals from the basal ganglia through the motor cortex to the cerebellum-ventral intermediate nucleus circuit. The cortico–striato–pallidal loop is responsible for mediating pallidi-associated sleep disorders. Medication and deep brain stimulation are the primary therapeutic strategies addressing the globus pallidus in Parkinson's disease. Medication is the primary treatment for motor symptoms in the early stages of Parkinson's disease, while deep brain stimulation has been clinically proven to be effective in alleviating symptoms in patients with advanced Parkinson's disease,particularly for the movement disorders caused by levodopa. Deep brain stimulation targeting the globus pallidus internus can improve motor function in patients with tremordominant and non-tremor-dominant Parkinson's disease, while deep brain stimulation targeting the globus pallidus externus can alter the temporal pattern of neural activity throughout the basal ganglia–thalamus network. Therefore, the comp

By modulating the crystalline properties of the active layer with dual donors, the efficiency of organic solar cells reaches 19.23%.The introduction of PTzBI-dF suppresses the accumulation of traps and charge recombination, allowing ternary devices to maintain 82% of their initial power conversion efficiency (PCE) after illumination for 800 *** dual-donor strategy for modulating the crystallinity of the active layer is applicable to a variety of Y6 derivatives, and the increase in PCE exceeds 1%. Trap-assisted charge recombination is one of the primary limitations of restricting the performance of organic solar cells. However, effectively reducing the presence of traps in the photoactive layer remains challenging. Herein, wide bandgap polymer donor PTzBI-dF is demonstrated as an effective modulator for enhancing the crystallinity of the bulk heterojunction active layers composed of D18 derivatives blended with Y6, leading to dense and ordered molecular packings, and thus, improves photoluminescence quenching properties. As a result, the photovoltaic devices exhibit reduced trap-assisted charge recombination losses, achieving an optimized power conversion efficiency of over 19%. Besides the efficiency enhancement, the devices comprised of PTzBI-dF as a third component simultaneously attain decreased current leakage, improved charge carrier mobilities, and suppressed bimolecular charge recombination, leading to reduced energy losses. The advanced crystalline structures induced by PTzBI-dF and its characteristics, such as well-aligned energy level, and complementary absorption spectra, are ascribed to the promising performance improvements. Our findings suggest that donor phase engineering is a feasible approach to tuning the molecular packings in the active layer, providing guidelines for designing effective morphology modulators for high-performance organic solar cells.

本研究对兄弟姐妹数量与青少年成长之间的关系进行了全面的理论探讨,并利用2010—2018年中国家庭追踪调查数据,为识别兄弟姐妹对青少年认知能力和主观幸福感的影响提供了微观证据。实证研究结果表明:拥有1个兄弟姐妹对青少年的主观幸福感有积极影响,这种影响效应随年龄增长而加强,并且在成年后依旧保持稳定;拥有兄弟姐妹可能对青少年的数学类认知能力产生负向影响,这种影响主要体现在较低学段样本中,并随年龄增长逐渐消失。本研究为父母制定生育决策时更有效地开展成本收益分析提供了支持,也为缓解养育焦虑、完善生育政策以及促进人口可持续发展提供了政策启示。

Analytical prediction of the maximum temperature of non-uniform heated surface with channel cooling

引用

Science China Technological Sciences 2025年第1期 177-188页

作者： Xiangyu WANG Xianghua XU Xingang liang School of Aerospace Engineering Tsinghua University

Active cooling of aircraft skin has garnered significant attention from researchers in recent years due to the increasing flight speeds. The determination of the maximum temperature plays a crucial role in the design of active cooling systems as it dictates the selection of suitable materials for aircraft skin. This research presents two analytical models for predicting surface temperatures in aircraft skin with active cooling channels: one for densely arranged channels and another for sparsely arranged channels. The application criteria of these two models are obtained. The analytical models offer several advantages, including handling non-uniform heat fluxes and providing direct predictions of maximum temperature and its location. Numerical simulations validate these models, demonstrating their accurate estimation capabilities across various solid materials, Reynolds numbers, and thermal conductivities. This investigation lays the foundation for rapid and cost-effective design of optimal cooling channels based on solid thermal conductivity, cooling flow rate, channel spacing, and temperature limits under non-uniform heat flows. Furthermore, an examination of channel aspect ratios reveals that larger ratios result in lower heated surface temperatures. Overall, these analytical temperature prediction models serve as efficient tools for selecting appropriate design parameters for active cooling channels.
