Rare Metals, EarlyView.ABSTRACT Skin wound injuries are often accompanied by bacterial infections and severe inflammation. Especially, M1‐type macrophages at the wound site can trigger a cascade of inflammatory responses, mediating a vicious cycle of inflammation. Meanwhile, hypoxia further exacerbates vascular damage and constriction in the wound microenvironment, thereby ...

American Journal of Botany, Volume 112, Issue 11, November 2025.Abstract Premise The proper classification of taxa is often debated, particularly when organisms lack qualitative diagnostic traits. Highbush cranberry taxa (Viburnum spp.) have been the subject of such disputes since their characterization by 18th‐ and 19th‐century botanists. Despite their allopatric distributions—V.

Evolution of petal patterning: blooming floral diversity at the microscale
New Phytologist, Volume 247, Issue 6, Page 2538-2556, September 2025.Summary The flowers of angiosperms are extraordinarily diverse. While most floral variation is visible to the naked eye, this diversity goes beyond the macroscale: Floral organs comprise an underappreciated range of cell types that generate a multitude of patterns across their surfaces and give rise to novel structures.

The discovery of new biomarkers of hepatocellular carcinoma [PDF]
, 2017 肝癌，尤其是肝细胞型肝癌是一种常见的恶性肿瘤，发现晚且死亡率高，因此及时发现、尽早治疗具有重要的临床意义。而生物标志物可作为早期临床诊断的工具，可显著提高患者的生存率。当前临床常用的肝细胞型肝癌的血清早期诊断标志物主要有甲胎蛋白（AFP）和甲胎蛋白异质体（AFP-L3）等，但这些检测指标的灵敏度和特异性均有待提高。而外泌体是一种与肿瘤的发生、发展密切相关的分泌型囊泡。已有报道显示，许多肿瘤中均可分泌包含特异的、可做潜在生物标志物的外泌体，因此，利用外泌体寻找生物标志物是目前研究的热点 ...
