Constraints on holographic QCD phase transitions from PTA observations

Science China(Physics,Mechanics & Astronomy) 2025年第1期Mechanics & Astronomy) .卷 71-78页

The underlying physics of QCD phase transition in the early Universe remains largely unknown due to its strong-coupling nature during the quark-gluon plasma/hadron gas transition, yet a holographic model has been proposed to quantitatively fit the lattice QCD data while with its duration of the first-order phase transition(FoPT) left undetermined. At specific baryon chemical potential, the first-order QCD phase transition agrees with the observational constraint of baryon asymmetry. It, therefore, provides a scenario for phase transition gravitational waves(GWs) within the standard model of particle physics. If these background GWs could contribute dominantly to the recently claimed common-spectrum red noise from pulsar timing array(PTA) observations, the duration of this FoPT can be well constrained, and the associated primordial black holes are still allowed by current observations.

关键词： pulsar timing array QCD phase transition gravitational waves primordial black holes

The effects of exercise interventions on brain-derived neurotrophic factor levels in children and adolescents:a meta-analysis

Neural Regeneration Research 2025年第5期20卷 1513-1520页

作者： Xueyun Shao Longfei he Yangyang Liu Physical Education School Shenzhen UniversityShenzhenGuangdong ProvinceChina Shenzhen Institute of Neuroscience ShenzhenGuangdong ProvinceChina

Brain-derived neurotrophic factor is a crucial neurotrophic factor that plays a significant role in brain health. Although the vast majority of meta-analyses have confirmed that exercise interventions can increase brain-derived neurotrophic factor levels in children and adolescents, the effects of specific types of exercise on brain-derived neurotrophic factor levels are still controversial. To address this issue, we used meta-analytic methods to quantitatively evaluate, analyze, and integrate relevant studies. Our goals were to formulate general conclusions regarding the use of exercise interventions, explore the physiological mechanisms by which exercise improves brain health and cognitive ability in children and adolescents, and provide a reliable foundation for follow-up research. We used the Pub Med, Web of Science, Science Direct, Springer, Wiley Online Library, Weipu, Wanfang, and China National Knowledge Infrastructure databases to search for randomized controlled trials examining the influences of exercise interventions on brain-derived neurotrophic factor levels in children and adolescents. The extracted data were analyzed using Review Manager 5.3. According to the inclusion criteria, we assessed randomized controlled trials in which the samples were mainly children and adolescents, and the outcome indicators were measured before and after the intervention. We excluded animal experiments, studies that lacked a control group, and those that did not report quantitative results. The mean difference(MD;before versus after intervention) was used to evaluate the effect of exercise on brain-derived neurotrophic factor levels in children and adolescents. Overall, 531 participants(60 children and 471 adolescents, 10.9–16.1 years) were included from 13 randomized controlled trials. heterogeneity was evaluated using the Q statistic and I^(2) test provided by Review Manager software. The meta-analysis showed that there was no heterogeneity among the studies(P = 0.67,

成束状阿拉伯半乳糖蛋白(FLAs)在木质部发育过程中起重要调控作用,对山新杨(Populus davidiana×*** ***)FLA基因进行生物信息学及其在山新杨不同组织中的表达模式进行了分析,筛选与木质部发育相关的FLA基因,为鉴定其调控山新杨材性形成的调控机制及分子改良奠定基础。利用拟南芥FLA家族蛋白序列在山新杨基因组序列中进行比对,共获得11条PdbFLAs,编码区长度为540至1 440 bp。对其蛋白理化性质、高级结构、系统进化、基序分布、启动子元件等进行分析。结果表明:蛋白结构和基序分析可将PdbFLAs分为3个亚类,每个亚类的蛋白结构和基序组成较为保守;系统进化分析可将PdbFLAs分为4组,这其中PdbFLA1、PdbFLA2、PdbFLA4、PdbFLA9与毛果杨、拟南芥中调控本质部发育相关基因聚为一组,推测该组内的PdbFLAs也具有类似功能;在PdbFLAs启动子中发现了与光、脱落酸(ABA)、胁迫响应和次生壁形成相关的重要顺式元件。对人工弯曲处理的山新杨木质部表型进行分析,发现树干出现偏心生长,应拉木组织被染成绿色,显示其纤维素质量分数高于对应木和直立木,木质化程度有所降低。利用荧光定量RT-PCR对PdbFLAs在根、茎、叶以及应拉木、对应木和直立木不同组织的表达模式进行分析,结果显示:PdbFLA1在茎和应拉木中高度表达,说明在山新杨木质部发育过程中PdbFLA1具有重要的调控作用。

Dip2a regulates stress susceptibility in the basolateral amygdala

引用

Neural Regeneration Research 2025年第6期20卷 1735-1748页

作者： Jing Li Zixuan he Weitai Chai Meng Tian Huali Yu Xiaoxiao he Xiaojuan Zhu Key Laboratory of Molecular Epigenetics Ministry of Education Institute of Genetics and CytologyNortheast Normal UniversityChangchunJilin ProvinceChina

Dysregulation of neurotransmitter metabolism in the central nervous system contributes to mood disorders such as depression, anxiety, and post–traumatic stress disorder. Monoamines and amino acids are important types of neurotransmitters. Our previous results have shown that disco-interacting protein 2 homolog A(Dip2a) knockout mice exhibit brain development disorders and abnormal amino acid metabolism in serum. This suggests that DIP2A is involved in the metabolism of amino acid–associated neurotransmitters. Therefore, we performed targeted neurotransmitter metabolomics analysis and found that Dip2a deficiency caused abnormal metabolism of tryptophan and thyroxine in the basolateral amygdala and medial prefrontal cortex. In addition, acute restraint stress induced a decrease in 5-hydroxytryptamine in the basolateral amygdala. Additionally, Dip2a was abundantly expressed in excitatory neurons of the basolateral amygdala, and deletion of Dip2a in these neurons resulted in hopelessness-like behavior in the tail suspension test. Altogether, these findings demonstrate that DIP2A in the basolateral amygdala may be involved in the regulation of stress susceptibility. This provides critical evidence implicating a role of DIP2A in affective disorders.
