Research on design and control method of active vibration isolation system based on piezoelectric Stewart platform.

Space payloads in orbit are vulnerable to small vibrations from satellite platforms, which can degrade their performance. Traditional methods typically involve installing a passive vibration isolation system between the platform and the payload. However, such systems are usually effective only for high-frequency, large-amplitude vibrations and perform poorly in isolating low-frequency vibrations and resonances below 10 Hz.

LncRNA XIST, as a ceRNA of miR-204, aggravates lipopolysaccharide-induced acute respiratory distress syndrome in mice by upregulating IRF2.

Background: Acute respiratory distress syndrome (ARDS) is a common clinical syndrome with high a mortality rate, which is associated with diffuse alveolar injury and capillary endothelial damage. In recent years, numerous studies have been performed to explore the roles of long non-coding RNAs (lncRNAs) in various diseases in which lncRNA serves as a microRNA (miRNA) sponge to regulate targeted gene expression. However, whether lncRNAs participate in ARDS progression remains unclear.

Long non-coding RNA-HOTAIR promotes the progression of sepsis by acting as a sponge of miR-211 to induce IL-6R expression.

Sepsis remains the primary cause of death in intensive care units and multiple long non-coding RNAs (lncRNAs) have been demonstrated to be dysregulated in samples of patients with sepsis. However, whether lncRNA-HOTAIR is involved in the etiology of sepsis remains unclear. The aim of the present study was to investigate the role of HOTAIR in sepsis and to reveal the associated mechanisms.
