ABSTRACT Sleep deprivation (SD) has been associated with a plethora of severe pathophysiological syndromes, including gut damage, which recently elucidated as an outcome the accumulation reactive oxygen species (ROS). However, spatiotemporal analysis conducted in this study intriguingly shown that specific events cause harmful damage to gut, particularly goblet cells, before lethal ROS. Transcriptomic and metabolomic analyses have identified significant enrichment metabolites related...

Chondrocyte senescence play an essential role in osteoarthritis (OA) progression. Recent studies have shown that snoRNA-derived RNA fragments (sdRNAs) are novel regulators of post-transcriptional gene expression. However, the expression profiles and their regulation chondrocyte OA progression is unknown. Here, we determined sdRNAs profile explored sdRNA-D43 its mechanism. We used qPCR arrays to determine chondrocytes areas undamaged damaged three knee samples. SdRNA-D43 was using...

The Alveolar soft-part sarcoma (ASPS) involving the lung is mostly metastatic, while primary ASPS occurs more rarely. Herein, we reported on another case of ASPS, which might be with earliest onset thus far. In this report, surgery was used to excise lesion as much possible, and its combination chemoradiotherapy anti-angiogenic agent may provide an important reference for development standard treatment or first-line these children patients.
