Recent years have seen the publication of several high-profile, negative trials about pressure wires. This has coincided with a consistent increase in the ratio of angioplasty for acute coronary syndromes versus percutaneous coronary intervention in stable coronary artery disease, a greater use of intracoronary imaging during percutaneous coronary intervention and the continued evolution of computational fluid dynamics-derived estimations of fractional flow reserve from both CT and invasive coronary angiography. Consequently, many interventional cardiologists now wonder if the pressure wire will soon become obsolete. This head-to-head article provides a critical appraisal of recent trial data, discusses a potential evolution in how pressure wires are used and debates the motion that the device (and by extension, invasive assessment of coronary physiology) has now had its day.

Constructing a nanofibrous membrane with high flow rate surface pore structure and high-density ligand chemical structure is a promising strategy to balance the trade-off between high flow rates and high adsorption capacity for protein separation and purification. Herein, a nanofiber-based ion-exchange chromatography membrane with a periodic diagonal surface structure and high ionic strength ligands was fabricated using dispersion cross-linking, wet coating, and template printing with a three-wire diagonal woven mesh. For this membrane, EVOH nanofibers were used as skeleton, glutaraldehyde (GA) as cross-linking agent, and quaternized chitosan (QCS) as binder and functional ligand.

The solder burrs on the 304V wire surface can easily scratch the vascular tissue during interventional treatment, resulting in complications such as medial tears, bleeding, dissection, and rupture. Abrasive blasting is often used to remove solder burr and obtain a smooth surface for the interventional device. This study conducted an abrasive blasting experiment to explore the effects of process parameters (air pressure, lift-off height, abrasive volume, and abrasive type) on processing time, surface roughness, and mechanical properties to reveal the material removal mechanism.

Background: Angina with no obstructive coronary artery disease (ANOCA) occurs in approximately 40 % of patients who undergo diagnostic coronary angiography for symptoms of angina. Coronary physiology assessment (CPA) is a guideline proven method to assess and diagnose these patients for an effective treatment strategy. There is currently no data regarding optimal wire or sensor position for CPA using bolus coronary thermodilution.

Given that conducting controllable shock wave tests in actual rock formations underground in coal mines affects coal mine production with the parameters required for equipment design and incurs significant costs, a series of ground tests were conducted separately. First, the impact of energy storage on rock breaking efficiency was analyzed. Then, physical simulation experiments were conducted on the differential efficiency of controllable shock waves on high-strength cement, sandstone, granite, solid granite, and limestone.

Large amounts of wastewater are produced from semiconductor manufacturing, and the production energy consumption has skyrocketed with its global demand in recent years. Forward osmosis (FO) provides unique merits in reclaiming the wastewater if suitable draw solutes with high water flux, low leakage, and limited energy requirement in regeneration are available. Two lower critical solution temperature-ionic liquids (LCST-ILs), tetrabutylphosphonium trimethylbenzensulfonate ([P][TMBS]) and tetrabutylphosphonium maleate ([P][Mal]) were synthesized and systematically assessed as recycled draw solutes in FO for the water reclamation from the wastewater of Si-ingot sawing.
