Despite the great socioeconomic burden of stroke, there have been few reports stroke statistics in Korea. In this scenario, Epidemiologic Research Council Korean Stroke Society launched "Stroke Statistics Korea" project, aimed at writing a contemporary, comprehensive, and representative report on epidemiology This contains general prevalence behavioral vascular risk factors, characteristics, pre-hospital system care, hospital management, quality outcomes. report, we analyzed most up-to-date...
The microstructural evolution and underlying grain growth mechanism of a {10–12}-twin-containing Mg alloy during annealing are investigated through quasi in situ electron backscatter diffraction measurements rolled AZ31 subjected to precompression along the rolling direction (RD). precompressed material shows partially twinned structure consisting region residual matrix region, this changes an almost twin-free grown grains with serrated boundaries twin- matrix-originated regions after at 250...
Skin cancer is a serious disease that affects people all over the world. Melanoma an aggressive form of skin cancer, and early detection can significantly reduce human mortality. In United States, approximately 97,610 new cases melanoma will be diagnosed in 2023. However, challenges such as lesion irregularities, low-contrast lesions, intraclass color similarity, redundant features, imbalanced datasets make improved recognition accuracy using computerized techniques extremely difficult. This...
Bioimpedance analysis (BIA) helps measuring the constituents of body noninvasively. Prior studies suggest that BIA-guided fluid assessment to predict survival in dialysis patients. We aimed evaluate clinical usefulness BIA for predicting rate hemodialysis patients Korea.We conducted a single-center retrospective study. All were diagnosed with end-stage renal disorder and started maintenance between June 2009 April 2014. was performed within 1(st) week from start hemodialysis. The classified...
The effects of pre-existing {10–12} extension twins on the precipitation behavior an extruded AZ80 material during aging and its mechanical properties after peak are investigated. containing twins—which formed by compression before (twinned material)—has a finer grain size higher dislocation density than material. Although hardnesses twinned materials almost same, time to reach hardness is considerably shorter in former latter (4 h 24 h, respectively). In material, high promotes continuous...
As an enveloped virus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) delivers its viral genome into host cells via fusion of the and cell membranes. Here, we show that ANO6/TMEM16F-mediated surface exposure phosphatidylserine is critical for SARS-CoV-2 entry ANO6-selective inhibitors are effective against infections. Application Spike pseudotyped virus (SARS2-PsV) evokes a cytosolic Ca2+ elevation ANO6-dependent externalization in ACE2/TMPRSS2-positive mammalian cells. A...
This study investigates the variations in microstructural characteristics of a pre-twinned Mg alloy with temperature subsequent annealing treatment. To this end, rolled AZ31 is compressed to 3% plastic strain along rolling direction (RD) activate {10-12} twinning and subsequently annealed at 200, 250, 300, 350, 400 °C. Numerous twins are formed throughout material, leading formation RD-oriented texture. At an 200 °C, no occur during annealing. As increases from 250 residual energy remaining...
Background/Objectives: The early detection of individuals at risk cognitive impairment is a clinical imperative. With the recent advancement digital devices, smartphone application-based assessment considered promising tool for screening and monitoring inside outside clinic. This study examined whether smartphone-based assessment, Brain OK, was valid evaluating performance identifying people impairment. Methods: We recruited 88 participants aged over 60. They completed two tests with...
Longitudinal standards for height and velocity are essential to monitor appropriate linear growth.We aimed construct in Korean children adolescents through the population-based longitudinal Kangwha study.Our study was a part of community-based prospective cohort from 1986 1999 with 800 school children.Height were recorded annually age 6 until final height.Results compared cross-sectional data 2007 National Growth Charts.Final 173.5 cm boys 160.5 girls.Although similar between standards, mean...
An AZ91–0.9Ca–0.6Y–0.5MM (AZXWMM91100) alloy, which has higher corrosion resistance, ignition and extrudability than a commercial AZ91 been developed recently. In this study, the AZXWMM91100 alloy is extruded at various temperatures (300–400 °C) ram speeds (1–14.5 mm/s), cracking behaviors, microstructure, tensile properties of materials are systematically analyzed. On basis pressure limit surface internal limit, extrusion diagram providing safe processing zone established. All within have...
This study aimed to investigate the anti-inflammatory, antioxidant, and anti-atopic dermatitis (AD) effects of haplopine, which is one active components in D. dasycarpus. Haplopine (12.5 25 μM) inhibited mRNA expressions inflammatory cytokines IL-6, TSLP, GM-CSF, G-CSF protein IL-6 GM-CSF TNF-α/INF-γ-stimulated HaCaT cells. In H2O2-induced Jukat T cells, haplopine (25 50 suppressed productions proinflammatory (IL-4, IL-13, COX-2) increased oxidative stress defense enzymes (SOD, CAT, HO-1) a...
To investigate growth response in children with either idiopathic short stature (ISS) or hormone (GH) deficiency (GHD).The data of prepubertal GHD ISS treated using recombinant human GH were obtained from the LG Growth Study database. further divided into partial and complete groups. factors predicting after 1 2 years treatment investigated.This study included 692 (98 ISS, 443 GHD, 151 GHD). After year, changes height standard deviation score (ΔHt-SDS) 0.78, 0.83, 0.96 respectively. Height...
The commercial AZ91 alloy and nonflammable SEN9 (AZ91–0.3Ca–0.2Y, wt%) are extruded at 300 °C 400 °C. Their microstructure, tensile compressive properties, low-cycle fatigue (LCF) properties investigated, with particular focus on the influence of extrusion temperature. In materials (300-materials), numerous fine Mg17Al12 particles inhomogeneously distributed owing to localized dynamic precipitation during extrusion, unlike those (400-materials). These suppress coarsening recrystallized...
