Coronary artery disease, especially acute myocardial infarction (AMI), is a leading cause of death in the Asia-Pacific region. The Korea Acute Myocardial Infarction Registry (KAMIR) is the first nationwide, prospective, multicenter registry of Korean patients with AMI. Since the KAMIR first began in November 2005, more than 70,000 patients have been enrolled, and 230 papers have been published (as of October 2018). Moreover, published data from the KAMIR have revealed different characteristics f

Left snuffbox approach is suitable for CAG and PCI compared with the conventional radial approach.

The H(+)-pyrophosphatase (V-PPase) of plant vacuolar membranes catalyzes the electrogenic translocation of H+ from the cytosol to vacuole lumen and, in parallel with the vacuolar H(+)-ATPase located in the same membrane, establishes the inside-acid, inside-positive H(+)-electrochemical potential difference responsible for energizing the H(+)-coupled transport of solutes into the vacuole. The results of previous investigations suggest that the gene encoding the substrate-binding subunit of the V-

Females has a significantly smaller distal RA diameter compared to males. Moreover, the success rate of the distal RA approach tends to be higher in men than in women.

The mixing-length theory (MLT) approximation (Vitense 1953) is used in most stellar evolution codes to describe the structure of the outer, highly superadiabatic, layers of the Sun. This procedure is known to be incorrect because of the MLT's inadequacies in describing convection and because of the need to include the strong coupling between radiation and convection in modeling this region. However, it is not known to what extent and precisely in what ways the MLT approximation distorts the stru

In the setting of STEMI, the DRA could be a feasible alternative access route for primary PCI.

To study the turbulent convection and the interaction with radiation around the highly superadiabatic layer (SAL), the fully compressible hydrodynamics equations in conservative forms and the equation of radiative transport with the generalized three-dimensional Eddington approximation have been solved, utilizing the "alternating direction implicit on staggered mesh" technique. The computational domain spanned a total of 4.4 pressure scale heights initially, which included about 2 pressure scale

In an attempt to understand the properties of convective energy transport in the solar convective zone, a numerical model has been constructed for turbulent flows in a compressible, radiation-coupled, nonmagnetic, gravitationally stratified medium using a realistic equation of state and realistic opacities. The time-dependent, three-dimensional hydrodynamic equations are solved with minimal simplifications. The statistical information obtained from the present simulation provides an improved und

The iM2-PK exhibited increased sensitivity for identifying CRC and adenomatous lesions compared with iFOBT. Given its rapid results and convenience, CRC screening using iM2-PK is promising.

This study demonstrated the noninferiority of AI-QCA-assisted PCI to OCT-guided PCI in achieving MSA with comparable OCT-defined endpoints. (Fully Automated Quantitative Coronary Angiography Versus Optical Coherence Tomography Guidance for Coronary Stent Implantation [FLASH]; NCT05388357).

The prevalence of SCAD was 8.7%, indicating that SCAD is not rare, among female patients aged less than 60 years with AMI in Korea. Type 2 SCAD was most commonly observed on angiogram. Moreover, the distal portion of the LAD was the segment most commonly affected by SCAD. The long-term clinical outcomes were favorable in patients surviving SCAD.
