Seroprevalence of measles antibody among immigrants in Gwangju, South Korea.

Introduction: Measles remains a public health concern, particularly among populations with suboptimal vaccination coverage, including immigrants. Understanding the seroprevalence of measles antibodies in immigrant populations is essential to inform tailored vaccination strategies and reduce the risk of measles reintroduction.

Methods: This study evaluated measles IgG seroprevalence among 651 immigrants from 30 countries residing in Gwangju, South Korea.

Whole Exome Sequencing of a Patient with a Milder Phenotype of Xeroderma Pigmentosum Group C.

A 17-year-old female Korean patient (XP115KO) was previously diagnosed with Xeroderma pigmentosum group C (XPC) by Direct Sanger sequencing, which revealed a homozygous nonsense mutation in the gene (rs121965088: c.1735C > T, p.Arg579Ter).

Lupus Miliaris Disseminatus Faciei versus Granulomatous Rosacea: A Case Report.

Lupus miliaris disseminatus faciei (LMDF) and granulomatous rosacea are 2 distinct inflammatory dermatoses with overlapping clinical features: reddish-yellow papular eruptions localized on the central face. Consequently, LMDF can easily be misdiagnosed as granulomatous rosacea or vice versa. Because delayed treatment in LMDF may increase chances of permanent scar formation, accurate diagnosis is important.

Re-evaluation of physicochemical and NMR data of triol ginsenosides Re, Rf, Rg2, and 20-gluco-Rf from Panax ginseng roots.

Ginseng roots were extracted with aqueous methanol, and extracts were suspended in water and extracted successively with ethyl acetate and n-butanol. Column chromatography using the n-butanol fraction yielded four purified triol ginseng saponins: the ginsenosides Re, Rf, Rg2, and 20-gluco-Rf. The physicochemical, spectroscopic, and chromatographic characteristics of the ginsenosides were measured and compared with reports from the literature.

Lignans and neolignans from the stems of Vibrunum erosum and their neuroprotective and anti-inflammatory activity.

A new lignan, (7'S,8S,8'S)-3,5'-dimethoxy-3',4,9'-trihydroxy-7',9-epoxy-8,8'-lignan, named vibruresinol (1), was isolated from the stems of Viburnum erosum by silica gel, ODS, and Sephadex LH-20 column chromatography. In addition, four other known lignans, (7'R,8S,8'S)-3,5'-dimethoxy-3',4,8',9'-tetrahydroxy-7',9-epoxy-8,8'-lignan (2), (+)-syringaresinol (3), (+)-pinoresinol (4), and (+)-pinoresinol-4-O-β-D-glucopyranoside (5), and five known neolignans, herpetol (6), vibsanol (7), (-)-dehydrodiconiferyl alcohol (8), icariside E4 (9), and dihydrodehydrodiconiferyl alcohol (10), were isolated in the same manner. The chemical structures of the compounds were determined based on spectroscopic data including NMR, MS, and IR.
