Previous station pull through techniques of anal canal pressure measurement have not truly represented the differences among individuals and between sexes in the length and pressure profile of the anal canal. Furthermore, the techniques commonly used in anal canal pressure determination have not been adequately compared or standardised. Therefore, a mechanised rapid pull through technique using...

OBJECTIVES We aimed to validate the technique of measuring the coronary flow reserve (CFR) with coronary pressure measurements against an established thermodilution technique. BACKGROUND The CFR has traditionally required measurement of coronary blood flow velocity with the Doppler wire and, more recently, using a thermodilution technique with the coronary pressure wire. However, recent work ...

introduction: this study aimed to evaluate the effects of four-time inflation of the stent balloon at nominal pressure on optimal stent expansion in resistant lesions. materials and methods: this interventional study was conducted on 39 patients with coronary artery lesions, in whom zotarolimus-eluting stents (n=20), paclitaxel-eluting stents (n=11) and other stents (n=8) were deployed four tim...

abstract background: hypertensive disorders in pregnancy are the main cause of maternal and fetal mortality; however, they have no definite effective treatment. the researchers aimed to study the effects of progressive muscular relaxation and breathing control technique on blood pressure (bp) during pregnancy. materials and methods: this three‑group clinical trial was conducted in mashhad healt...

Vortex extrusion (VE) is a severe plastic deformation technique which is based on the synergies between high strain accumulation and high hydrostatic pressure. Such a high amount of pressure, places a mandate to seek the method for investigation of the load under processing conditions. For this, kinematically admissible velocity field and upper bound terms based on Bezier formulation are develo...

An efficient amide synthesis by atmospheric pressure aminocarbonylation using palladium nanoparticles supported on MOF-5 is reported. Interestingly, only 0.5 wt% palladium loading was required to achieve high yields. The catalyst is recyclable and offers negligible palladium leaching.
