Purpose: Ischemia-reperfusion (I/R) injury exacerbates myocardial cell death (including apoptosis and necrosis), leading to complications such as arrhythmias, stenosis, microvascular obstruction heart failure, it is particularly important seek new strategies mitigate reperfusion injury. In this paper, we will investigate whether atorvastatin can alleviate ischemia-reperfusion verify its molecul...

Electrospinning was applied to nitrocellulose (NC) solutions  in DMF, DMSO  and  Ethyl  methyl  keton  to  obtain  NC  nanofibers. Electrospraying  process  was  observed  when  DMF  was  used  as solvent.  In  comparison  to NC/DMF, NC/DMSO  solution  resulted  in the  formation  of  a  coating  film  as  indicate  by  SEM.  Two  different electrospun  nanofibers,  smooth  nanofibers  wit...

BACKGROUND Superficial culture has a high negative predictive value in the assessment of catheter tip colonization (CC) and catheter-related bloodstream infection (C-RBSI). However, the process of hub culture requires the hubs to be swabbed, and this carries a risk of dislodging the biofilm. At present, most catheter hubs are closed by needleless connectors (NCs) that are periodically replaced....

The aim of this paper is to explore some aspects of the syntax-semantics interface representations which correspond to expletive negation (EN) and negative concord (NC). I shall postulate that a syntactic operation of logical absorption, conceived as feature checking, is needed in the theory of grammar in order to account for both phenomena. EN instantiates a nonnegative context; it will be cha...

The paper presents the state-space (SS) model of brushless double-fed machine (BDFM) by taking negative conjugate (NC) transformation power machine’s correlation variable when current source control is supplied in m-t reference frame. Based on this, testing method parameters given, and SS described five obtained. derivation process realization slip-frequency vector feedback linearization (SFV-F...
