Hypertrophied and failing cardiac myocytes generally show alterations in intracellular Ca handling associated with changes in the contractile function and arrhythmogenicity. The cardiac Na -Ca exchange (NCX) is an important mechanism for Ca extrusion and cell relaxation. Its possible involvement in changes of excitation-contraction coupling (EC-coupling) with disease remains uncertain. We analy...

BACKGROUND This small study has determined the effect of vitamin C on myocardial reperfusion in patients undergoing elective percutaneous coronary intervention (PCI). This study was to explore whether antioxidant vitamin C infusion before the procedure is able to affect the incidence of periprocedural myocardial injury (PMI) in patients undergoing PCI. METHODS In this prospective single-centr...

An estimation of the post mortem interval (PMI) is frequently touted as the Holy Grail of forensic pathology. During the first hours after death, PMI estimation is dependent on the rate of physical observable modifications including algor, rigor and livor mortis. However, these assessment methods are still largely unreliable and inaccurate. Alternatively, RNA has been put forward as a valuable ...

Type I phosphomannose isomerase (PMI) is a Zn-dependent metalloenzyme involved in the isomerization of D-fructose 6-phosphate to D-mannose 6-phosphate. One of our laboratories has recently designed and synthesized 5-phospho-D-arabinonohydroxamate (5PAH), an inhibitor endowed with a nanomolar affinity for PMI (Roux et al., Biochemistry 2004, 43, 2926). By contrast, the 5-phospho-D-arabinonate (5...

Precordial and intracardiac phonocardiographic correlation was investigated in 28 cases with ventricular septal defect (VSD) to confirm the diagnostic value of intracardiac phonocardiography and to clarify the clinical as well as physiological significance of the point of maximum intensity (PMI) of the regurgitant systolic murmur of VSD. At the same time, the teleological use of catheterization...

PURPOSE The aim of this study was to determine whether the panoramic mandibular index (PMI) is useful for assessing bone mineral density. We also analyzed the potential correlations between PMI parameters and patient age. MATERIALS AND METHODS Four observers measured the PMI of both sides of the mental foramen using a picture archiving and communication system and images in the Digital Imagin...

BACKGROUND Following a legal agreement with the European Union (EU), Philip Morris International (PMI) commissions a yearly report ('Project Star', PS) on the European illicit cigarette trade from KPMG, the global accountancy firm. METHODS Review of PS 2010 report. Comparison with data from independent sources including a 2010 pan-European survey (N=18,056). FINDINGS Within PS, data coverin...

BACKGROUND Evidence suggests that high-dose statin pretreatment may reduce the risk of periprocedural myocardial infarction (PMI) and major adverse cardiac events (MACE) for certain patients; however, previous analyses have not considered patients with a history of statin maintenance treatment. In this meta-analysis of randomized controlled trials (RCTs), we reevaluated the efficacy of short-te...

BACKGROUND To analyze the effect of immediate treatment of perioperative myocardial ischemia (PMI) because of early graft failure or incomplete revascularization in patients undergoing coronary artery bypass grafting (CABG) surgery. METHODS AND RESULTS Between January 2004 and December 2010, 7461 patients underwent isolated CABG at our institution. All patients showing evidence of PMI (n=399;...

Video Model Deformation (VMD) and Projection Moiré Interferometry (PMI) were used to acquire wind tunnel model deformation measurements of the Northrop Grumman-built Smart Wing tested in the NASA Langley Transonic Dynamics Tunnel. The F18-E/F planform Smart Wing was outfitted with embedded shape memory alloys to actuate a seamless trailing edge aileron and flap, and an embedded torque tube to g...
