Effect of Bevacizumab on traumatic penumbra brain edema in rats at different time points.

Traumatic penumbra (TP) is a secondary injury area located around the core area of traumatic brain injury after brain trauma, and is an important factor affecting the outcome of traumatic brain injury (TBI). The main pathological change caused by TP is brain edema, including (cellular brain edema and vascular brain edema). The formation and development of brain edema in the TP area are closely related to the blood-brain barrier (BBB) and vascular endothelial growth factor (VEGF).

The functional role of lncRNAs as ceRNAs in both ovarian processes and associated diseases.

Long non-coding RNAs (lncRNAs) have attracted significant scientific attention due to their central role in regulating gene expression and their profound impact on the intricate mechanisms of ovarian function. These versatile molecules exert their influence through various mechanisms, including the coordination of transcription processes, modulation of post-transcriptional events, and the shaping of epigenetic landscapes. Furthermore, lncRNAs function as competitive endogenous RNAs (ceRNAs), engaging in intricate interactions with microRNAs (miRNAs) to finely adjust the expression of target genes.
