Population structure and mitogenomic analyses reveal dispersal routes of Macrobrachium nipponense in China by Penghui Luo, Yiting Jin, Ting Zhao, Chao Bian, Zhimin Lv, Na Zhou, Jianguang Qin, Shengming Sun

“…We performed whole-genome resequencing of 100 samples and assembled mitogenomes for population analysis, these two types of mitochondrial markers (cox1 and all 13 protein-coding genes—13 PCGs), a nuclear marker (28S rRNA) and SNPs to infer the relationships between the five populations, the population structure, and migratory routes. We also assembled complete mitogenome per sampled population (5 in total) and used them to conduct comparative mitogenomic analyses. …”

rTMS-induced neuroimaging changes measured with structural and functional MRI in autism by Xiaodong Kang, Kai Chen, Fei Wang, Linyi Mu, Zengzhen Lei, Rufei Zhang, Zedong Wang, Tao Zhang, Tao Zhang

“…Repetitive transcranial magnetic stimulation (rTMS) has emerged as a promising non-invasive neuromodulation technique; however, its neural mechanisms and clinical efficacy in children with ASD require further investigation.MethodsThis study enrolled 14 children diagnosed with ASD to undergo a structured rTMS intervention. Neuroimaging data—including voxel-based morphometry (VBM) and resting-state functional connectivity (FC)—as well as behavioral assessments were collected before and after the intervention to evaluate changes in brain structure, function, and symptomatology.ResultsPost-intervention analyses revealed significant increases in gray matter volume (GMV) in the cerebellar Vermis, Caudate nucleus, and Postcentral gyrus. …”

An Experimental Dynamic Investigation of the Influence of Melatonin, Serotonin and Tryptophan on the Stability of the DNA Structure by Cristina Manuela Drăgoi, Anca Zanfirescu, Ion-Bogdan Dumitrescu, Anca Ungurianu, Denisa Marilena Margină, Alina-Crenguţa Nicolae

“…Results: Our study offers detailed insights into the interaction patterns of the indole derivatives with DNA and is highly supported by molecular docking analyses: the indole derivatives were predominantly localized between C and G, interacting via π-π interactions and hydrogen bonds and aligning with known data on conventional intercalators. These findings underscore the importance of small compounds’ planar structure and appropriate size, facilitating tight insertion between adjacent base pairs and disrupting regular DNA stacking. …”
