Several metabolomics of polymeric flavan-3-ols have reported that proanthocyanidins are extensively metabolized by gut microbiota. 5-(3',4'-dihydroxyphenyl)-γ-valerolactone (DHPV) has been reported to be the major microbial metabolite of proanthocyanidins. We demonstrated that DHPV has stronger prevention effect on tumor necrosis factor (TNF)-α-stimulated adhesion of THP-1 human monocytic cells to human umbilical vein endothelial cells compared to its potential precursors such as procyanidin A1,

Advancements in NGS technologies have significantly expanded the scope and efficiency of metagenomics, surpassing traditional culture-based methods (Fig. 2).These innovations enable multi-domain microbial analysis through advanced bioinformatics tools, long-read sequencing, single-cell omics, and enhanced culture-based techniques, facilitating deeper insights into microbial diversity, function, and host interactions.The integration of cutting-edge computational tools and experimental methodologi

Information on sex differences in the association between chronotype and depression is scarce. We aimed to investigate these differences using data from the Korea National Health and Nutrition Examination Survey in 2016. Chronotypes were categorised based on mid-sleep time on free days corrected by sleep debt accumulated on workdays (MSFsc): early type, < mean MSFsc - 1 standard deviation (SD); intermediate type, between mean MSFsc - 1 SD and MSFsc + 1 SD; and late type, > mean MSFsc + 1 SD.

Cutaneous allodynia (CA) is a pain in response to non-nociceptive stimulation and a marker of central sensitisation. Probable migraine (PM) is a migraine subtype that fulfils all but one criterion of migraine. Headache intensity and the disability of individuals with PM are similar or lower than individuals with migraine. This study compared CA prevalence and characteristics of PM and migraine using a nationally representative sample in Korea. The Allodynia Symptom Checklist-12 (ASC-12) was used

Considerable attention is given to drug delivery technology that efficiently delivers appropriate levels of drug molecules to diseased sites with significant therapeutic efficacy. Nanotechnology has been used to develop various strategies for targeted drug delivery, while controlling the release of drugs because of its many benefits. Here, a delivery system was designed to control drug release by external magnetic fields using porous silica and magnetic nanoparticles. Magnetic nanochains (MNs) o

Importance: Many epidemiologic studies have suggested that low levels of plasma leptin, a major adipokine, are associated with increased risk of Alzheimer disease (AD) dementia and cognitive decline. Nevertheless, the mechanistic pathway linking plasma leptin and AD-related cognitive decline is not yet fully understood. Objective: To examine the association of plasma leptin levels with in vivo AD pathologies, including amyloid-beta (Aβ) and tau deposition, through both cross-sectional and longit

BACKGROUND AND PURPOSE: We investigated the relationship between transcranial Doppler (TCD) pulsatility index (PI) and central aortic pressure by measurement of the aortic augmentation index (AIx). METHODS: We enrolled 148 consecutive patients with a diagnosis of acute ischemic stroke. Patients were eligible for the study if they experienced their first ischemic stroke within the preceding 7 days and were 45 years of age or older. At Day 7 (±2) after stroke onset, TCD studies were performed and

Krüppel‑like factor 15 (KLF15), also known as kidney‑enriched transcription factor, is known to participate in podocyte differentiation. However, the role of KLF15 in chronic podocyte injury remains incompletely understood, particularly in proteinuric disease models. In the present study, the 5/6 nephrectomy mouse model was used to induce chronic podocyte injury. Human primary podocytes were isolated by flow cytometry and cultured to emulate the injury process in an in vitro system. Biopsied kid

PURPOSE: Acute promyelocytic leukemia (APL) is a rare disease in children and there are some different characteristics between children and adult. We aimed to evaluate incidence, clinical characteristics and treatment outcomes of pediatric APL in Korea. MATERIALS AND METHODS: Seventy-nine pediatric APL patients diagnosed from January 2009 to December 2016 in 16 tertiary medical centers in Korea were reviewed retrospectively. RESULTS: Of 801 acute myeloid leukemia children, 79 (9.9%) were diagnos

OBJECTIVES: We measured the carotid intima-media thickness, a surrogate marker of early atherosclerosis, in patients with carpal tunnel syndrome compared to a control group to evaluate the risk of atherosclerotic disease. METHODS: Between January 2011 and December 2011, female patients presenting to the outpatient neurology clinic for pain and paresthesia in the hands were screened for study enrollment. Patients 30 years or older were eligible for the study if they did not have a history of stro

Purpose: Unique features of adolescent cancer patients include cancer types, developmental stages, and psychosocial issues. In this study, we evaluated the relationship between diagnostic delay and survival to improve adolescent cancer care. Materials and Methods: A total of 592 patients aged 0–18 years with eight common cancers were grouped according to age (adolescents,≥10 years; children, <10 years). We retrospectively reviewed their symptom intervals (SIs, between first symptom/sign of disea

Purpose: Children and adolescents diagnosed with cancer experience emotional distress, such as sadness, worrying, and irritability. However, there is little information about the psychological well-being of parents at the time of their child’s diagnosis. We sought to identify factors that were associated with emotional distress in cancer patients as a basis for developing innovative psychologicalinterventions. Materials and Methods: A retrospective chart review was performed on patients newly di

Purpose: In childhood cancer survivors, the most common late effect is thyroid dysfunction, most notably subclinical hypothyroidism(SCH). Our study evaluated the risk factors for persistent SCH in survivors. Materials and Methods: Survivors (n=423) were defined as patients who survived at least 2 years after cancer treatment completion. Thyroid function was assessed at this time and several years thereafter. Two groups of survivors with SCH were compared: those who regained normal thyroid functi
