We analyzed the in vivo tumor regression activity of high molecular mass poly-gamma-glutamate (gamma-PGA) from Bacillus subtilis sups. chungkookjang. C57BL/6 mice were orally administered 10-, 100-, or 2000-kDa gamma-PGA beta-glucan (positive control), and antitumor immunity was examined. Our results revealed higher levels NK cell-mediated cytotoxicity IFN-gamma secretion treated with (2000 kDa) vs those lower (10 100 beta-glucan. then examined effect oral administration 10- on protection...

Many studies have reported conflicting evidence on the association between weight change and mortality. We investigated subsequent all-cause mortality, using a large-scale, population-based cohort from National Health Insurance System health checkup data 2005 2015. A total of 11,524,763 subjects older than age 20 years were included. Weight was measured every 2 over 4 divided into eight categories, loss ≥15% to gain ≥20%, for 5% change.
