Effect of Photobiomodulation on Platelet-Rich Fibrin Cellular Distribution and Fibrin Architectures: An In Vitro Split-Sample Controlled Experimental Study

这项体外拆分样本研究表明,光生物调节作用以波长依赖的方式显著增强了富血小板纤维蛋白的细胞分布、纤维蛋白结构和生长因子释放,其中 940 nm 最优地优化了结构完整性,而 660 nm 和 810 nm 则优先促进了特定的生长因子反应。

Growth heterogeneity of Streptococcus suis in host-mimicking conditions is independent of clinical origin

本研究表明,在模拟宿主条件下,不同菌株的兼利史特玲菌(*Streptococcus suis*)表现出具有菌株特异性的生长异质性,且这种现象与临床来源无关,凸显了代谢适应和营养可用性在塑造细菌适应性方面的关键作用。

Spatial and single-nucleus transcriptomics reveal the complexity of genomic imprinting in maize

通过整合空间转录组学和单核RNA测序,本研究揭示了玉米胚乳中的基因组印记具有高度的细胞类型特异性,其中大多数印记基因局限于单一细胞类型,且以父系表达基因为主,这表明受精后的分化塑造了这一表观遗传现象的空间与细胞复杂性。

Kolaviron Exerts Protection Against Atrazine-evoked Hepatorenal Injury by Targeting Apoptosis, Oxidative Stress, Inflammation Mediated Nf-kb/Cox-2/Il-1β and Beclin-1/Lc3-ii Signaling Cascades in Rats

本研究表明,来自非洲曼陀罗(*Garcinia kola*)的天然双黄酮类化合物——科拉维酮(kolaviron),通过调节 NF-κB/Cox-2/IL-1β 和 Beclin-1/LC3-II 信号通路,减轻氧化应激、炎症、细胞凋亡和自噬,从而有效保护大鼠免受莠近草诱导的肝肾损伤。
