The present study explored the possible antiobesogenic and osteoprotective properties of the gut metabolite ginsenoside CK to clarify its influence on lipid and atherosclerosis pathways, thereby validating previously published hypotheses. These hypotheses were validated by harvesting and cultivating 3T3-L1 and MC3T3-E1 in adipogenic and osteogenic media with varying concentrations of CK. We assessed the differentiation of adipocytes and osteoblasts in these cell lines by applying the most effective doses of CK that we initially selected.

Osteoarthritis (OA) is a chronic disease characterized by cartilage degradation, leading to bone friction, inflammation, stiffness, pain, and reduced mobility. This study investigates the therapeutic effects of porcine-derived chondroitin sulfate sodium (CS) on OA symptoms at both cellular and animal levels. study, HTB-94 chondrocytes were treated with inflammatory stimuli and CS (10, 50, 100, and 200 μg/mL) to assess the release of inflammatory mediators and the expression of genes and proteins related to cartilage synthesis and degradation.

Microsatellite markers are widely used in aquaculture for genetic analysis and breeding programs, but challenges such as segregation distortion and allelic instability can impact their effectiveness in parentage verification and inheritance studies. This study evaluated 15 microsatellite loci in seven experimental olive flounder () families bred through 1:1 full-sibling crosses, assessing their utility for accurate parentage and inheritance stability. Parentage assignments were conducted within an expanded pool of 647 candidate parents (including the actual 14 parents), encompassing both closely related and moderately distant individuals.

Chronic kidney disease (CKD) progresses through mechanisms involving inflammation, fibrosis, and oxidative stress, leading to the gradual structural and functional deterioration of the kidneys. Tormentic acid (TA), a triterpenoid compound with known anti-inflammatory and antioxidant properties, shows significant potential in counteracting these pathological processes. This study explored the protective role of TA in a unilateral ureteral obstruction (UUO)-induced CKD model.

Background: Ureteral stents, such as double-J stents, have become indispensable in urologic procedures but are associated with complications like hematuria and pain. While the advancement of artificial intelligence (AI) technology has led to its increasing application in the health sector, AI has not been used to provide information on potential complications and to facilitate subsequent measures in the event of such complications.

Objective: This study aimed to assess the effectiveness of an AI-based prediction tool in providing patients with information about potential complications from ureteroscopy and ureteric stent placement and indicating the need for early additional therapy.

Objectives: Physical activity (PA) provides protective effects against cardiovascular diseases, including ischaemic heart disease. However, recommending moderate to vigorous PA (MVPA) to patients with recent acute coronary syndrome (ACS) raises concerns owing to potential risk of recurrent ACS or fatal arrhythmias. This study investigated the association between longitudinal PA changes following an ACS diagnosis and subsequent cardiovascular outcomes, including non-fatal coronary events, non-fatal stroke and cardiovascular mortality.

Background: YYD601 is a new dual delayed-release formulation of esomeprazole, developed to enhance plasma exposure and prolong the duration of acid suppression.

Purpose: This study aimed to evaluate the safety, pharmacokinetic (PK), and pharmacodynamic (PD) profiles of YYD601 20 mg following single and multiple oral administrations in healthy, fasting adult Koreans, and to compare these outcomes to those of the conventional esomeprazole 20 mg capsule.

Methods: A randomized, open-label, two-period crossover study was conducted in 28 participants, who were divided into two treatment groups: one group received YYD601 20 mg, and the other received conventional esomeprazole 20 mg, once daily for five consecutive days.

Over the last decade, the functions of PHD finger protein 20 (PHF20) in several signaling processes have been studied, including those of protein kinase B (PKB)-mediated phosphorylation, p53 regulation, muscle differentiation, and histone modification including histone H3 lysine 4 (H3K4) methylation. One PHF20 human mutation lacks the first nonspecific lethal complex of the component that binds to H3K4me2 to facilitate cancer cell survival. In carcinoma cells, PHF20 expression is regulated by PKB; PHF20 becomes phosphorylated when DNA is damaged, thus inhibiting the p53 activity that maintains cancer cell survival.

Plant homeodomain finger protein 20 (PHF20) plays a crucial role in various biological processes, but its involvement in renal fibrosis remains unclear. This study investigated the role of PHF20 in renal fibrosis using a unilateral ureteral obstruction (UUO) mouse model, a widely accepted model for chronic kidney disease. PHF20 transgenic (PHF20-TG) and wild-type (WT) mice were utilized to explore how PHF20 influences renal inflammation and fibrosis.

Background: Abdominal aortic aneurysm (AAA) is more common in Non-small cell lung cancer (NSCLC) patients. Considering that ruptured AAA is potentially fatal, timely management of AAA would result in long-term survival benefits. We assess the prevalence and characteristics of AAA in resectable NSCLC patients who would benefit from AAA surveillance.

Background: Complete revascularization has demonstrated better outcomes in patients with acute myocardial infarction (AMI) and multivessel disease. However, in the case of left main (LM) culprit lesion AMI with multivessel disease, there is limited evidence to suggest that complete revascularization is better.

Methods: We reviewed 16,831 patients in the Korea Acute Myocardial Infarction Registry who were treated from July 2016 to June 2020, and 399 patients were enrolled with LM culprit lesion AMI treated with percutaneous coronary intervention.

Introduction: There is a lack of evidence to support the effectiveness of prolonged β-blocker therapy after stabilisation of patients with acute myocardial infarction (AMI) without heart failure (HF) or left ventricular systolic dysfunction.

Methods And Analysis: The SMart Angioplasty Research Team: DEcision on Medical Therapy in Patients with Coronary Artery DIsease or Structural Heart Disease Undergoing InterventiON (SMART-DECISION) trial is a multicentre, prospective, open-label, randomised, non-inferiority trial designed to determine whether discontinuing β-blocker therapy after ≥1 year of maintenance in stabilised patients after AMI is non-inferior to continuing it. Patients eligible for participation are those without HF or left ventricular systolic dysfunction (ejection fraction >40%) who have been continuing β-blocker therapy for ≥1 year after AMI.

Introduction And Objectives: Recent randomized controlled trials support the use of intravascular imaging-guided percutaneous coronary intervention (PCI) to improve patient prognosis. However, the subsequent risk of clinical events in patients with coronary artery disease is not determined solely by lesion characteristics or how these lesions are treated. The current study investigated whether the effects of intravascular imaging in complex PCI vary according to atherothrombotic risks.

Background: Data on the clinical impact of beta-blockers (BBs) in patients with myocardial infarction (MI) who had non-reduced left ventricular ejection fraction (LVEF) after percutaneous coronary intervention are limited.

Methods: From 2016 to 2020, we evaluated a cohort of 12,101 myocardial infarction patients with a non-reduced LVEF (≥40%) from the Korean Acute Myocardial Infarction Registry V. Patients were divided into two groups based on their BB (carvedilol, bisoprolol, or nebivolol) treatment at discharge: with beta-blocker treatment (BB,  = 9,468) and without beta-blocker treatment (non-BB,  = 2,633).
