Tracking and compensation of respiration pattern by an automatic compensation system.

Purpose: This study aimed to determine the feasibility of using an ultrasound image tracking algorithm (UITA) combined with a respiration compensating system (RCS) to track and compensate the respiration pattern of the diaphragm in real time.

Methods: Diaphragm motions and various respiration patterns were tracked and captured in volunteers using our previously developed UITA (Kuo et al., J Xray Sci Technol, 2016:875).

Conformational changes relevant to channel activity and folding within the first nucleotide binding domain of the cystic fibrosis transmembrane conductance regulator.

Deletion of Phe-508 (F508del) in the first nucleotide binding domain (NBD1) of the cystic fibrosis transmembrane conductance regulator (CFTR) leads to defects in folding and channel gating. NMR data on human F508del NBD1 indicate that an H620Q mutant, shown to increase channel open probability, and the dual corrector/potentiator CFFT-001 similarly disrupt interactions between β-strands S3, S9, and S10 and the C-terminal helices H8 and H9, shifting a preexisting conformational equilibrium from helix to coil. CFFT-001 appears to interact with β-strands S3/S9/S10, consistent with docking simulations.

[Acute superior mesenteric ischemia: a contrast study on short-and mid-term result between stent implantation and pharmaceutical thrombolysis].

Objective: To compare the short-term and medium-term result of stent implantation with pharmaceutical thrombolysis in patients with acute superior mesenteric artery occlusion.

Methods: From January, 2004 to December, 2008, thirty-five patients diagnosed acute superior mesenteric ischemia, 12 patients treated with stent implantation (interventional therapy group) and 23 patients with pharmaceutical thrombolysis (thrombolytic therapy group). Interventional therapy group treated with balloon dilatation and stent implantation assisted with anticoagulation, antiplatelet and vascular dilation agents.
