Despite efforts to develop treatment technology for cardiac arrest (CA),CA incidence and mortality rates are still high.^([1,2])A recent study of CA patients in emergency departments revealed that the incidence of CA is increasing annually,and the in-hospital survival rate of CA patients is only approximately 28.7%.^([3])Echocardiography has been widely used as an important monitoring tool in critical care and helps to identify the cause of shock,monitor hemodynamics,and guide fluid therapy utilization.^([4])One study reported that approximately one-third of patients underwent formal echocardiography during hospitalization in the intensive care unit (ICU).

Cytoplasmic male sterile(CMS) lines play a crucial role in utilization of heterosis in crop plants. However,the mechanism underlying the manipulation of male sterility in cotton by long non-coding RNA(lncRNA)and brassinosteroids(BRs) remains elusive. Here,using an integrative approach combining lncRNA transcriptomic profiles with virus-induced gene silencing experiments, we identify a flower budspecific lncRNA in the maintainer line 2074B,lncRNA67, negatively modulating with male sterility in upland cotton(Gossypium hirsutum). lncRNA67positively regulates cytochrome P274B(GhCYP7 24B), which acted as an eTM(endogenous target mimic) for miR3367. The suppression of GhCYP724B induced symptoms of BR deficiency and male semisterility in upland cotton as well as in tobacco, which resulted from a reduction in the endogenous BR contents. GhCYP724B regulates BRs synthesis by interacting with GhDIM and GhCYP90B, two BRs biosynthesis proteins. Additionally, GhCYP724B suppressed a unique chimeric open reading frame(Aorf27) in 2074A mitochondrial genome. Ectopic expression of Aorf27 in yeast inhibited cellular growth, and over expression of Aorf27 in tobacco showed male sterility. Overall, the results proved that the miR3367–lncRNA67–GhCYP724B module positively regulates male sterility by modulating BRs biosynthesis. The findings uncovered the function of lncRNA67–GhCYP724B in male sterility, providing a new mechanism for understanding male sterility in upland cotton.

Carbon nanotubes(CNTs) have garnered great attention in recent years due to their outstanding electrical, thermal, and mechanical properties. The incorporation of small amounts of CNTs in polymers can substantially improve the sensitivity of the polymer's electrical conductivity. This paper presents a modified Maxwell model to evaluate the electrical conductivity of CNTs-filled polymer composites by introducing a transition zone to account for the tunneling effect. In this modified Maxwell model, the CNTs-filled polymer composite is modeled as a three-phase composite, consisting of a matrix(polymer), inclusions(CNTs), and a transition zone(tunneling zone). The effective electrical conductivity(EEC) of the composite is calculated based on the volume fractions and electrical conductivities of the matrix, inclusions, and transition zone. The model's validity is confirmed through the use of available test data, which demonstrates its capability to accurately capture the nonlinear conductivity behavior observed in CNTs-polymer composites. This study offers valuable insights into the design of high-performance conductive polymer nanocomposites, and enhances the understanding of electrical conduction mechanisms in CNT-dispersed polymer composites.
