采用回收装置把制动能量回收到车上的能量储备器内,可提供显著降低车辆燃油消耗的可能。一种通用的技术是制动时在混合电驱动马达内产生电能,用它为车上电化学电池充电。然而这种电池价格昂贵、笨重,而且一般它不能承受快速充电,这将影响到它的寿命和容量。为了解决这样的问题,推荐和研究一种机械能储存装置,可接受和输送能量的波动。该装置的比例物理模型由飞轮载体、行星齿轮传动和一制动器组成,并已建成和运转在实验室内。试验表明,所推荐的装置可以用来储存和提供飞轮和车辆间制动能量,以后用一空气阻力测功器模拟,论证了该装置的运行原理和它的计算模型。进一步介绍了全尺寸车辆结合机械能量储存装置的计算分析,结果表明,该装置在车辆中使用,和通常的车辆相比较,可导致车辆的排放和燃油消耗降低。

MicroRNAs as potential diagnostic biomarkers for bipolar disorder

引用

Neural Regeneration Research 2025年第6期20卷 1681-1695页

作者： Bridget martinez philip V.peplow Department of pharmacology University of Nevada-RenoRenoNVUSA Department of Medicine University of Nevada-RenoRenoNVUSA Department of Anatomy University of OtagoDunedinNew Zealand

Abnormal expression of microRNAs is connected to brain development and disease and could provide novel biomarkers for the diagnosis and prognosis of bipolar disorder. We performed a pubMed search for microRNA biomarkers in bipolar disorder and found 18 original research articles on studies performed with human patients and published from January 2011 to June 2023. These studies included microRNA profiling in bloodand brain-based materials. From the studies that had validated the preliminary findings,potential candidate biomarkers for bipolar disorder in adults could be miR-140-3p,-30d-5p,-330-5p,-378a-5p,-21-3p,-330-3p,-345-5p in whole blood, miR-19b-3p,-1180-3p,-125a-5p, let-7e-5p in blood plasma, and miR-7-5p,-23b-5p,-142-3p,-221-5p,-370-3p in the blood serum. Two of the studies had investigated the changes in microRNA expression of patients with bipolar disorder receiving treatment. One showed a significant increase in plasma miR-134 compared to baseline after 4 weeks of treatment which included typical antipsychotics, atypical antipsychotics, and benzodiazepines. The other study had assessed the effects of prescribed medications which included neurotransmitter receptorsite binders(drug class B) and sedatives, hypnotics, anticonvulsants, and analgesics(drug class C) on microRNA results. The combined effects of the two drug classes increased the significance of the results for miR-219 and-29c with miR-30e-3p and-526b* acquiring significance. MicroRNAs were tested to see if they could serve as biomarkers of bipolar disorder at different clinical states of mania, depression, and euthymia. One study showed that upregulation in whole blood of miR-9-5p,-29a-3p,-106a-5p,-106b-5p,-107,-125a-3p,-125b-5p and of miR-107,-125a-3p occurred in manic and euthymic patients compared to controls, respectively, and that upregulation of miR-106a-5p,-107 was found for manic compared to euthymic patients. In two other studies using blood plasma,downregulation of miR-134 was observed i

Autism spectrum disorder:difficulties in diagnosis and microRNA biomarkers
