The Role of Oxidative Stress in Periodontitis
Journal of Periodontal Research, EarlyView.Oxidative stress is involved in multiple chemical reactions that take place in different intracellular organelles: mitochondria, rough endoplasmic reticulum, peroxisomes, autophagy, and aging, and can be influenced by exogenous factors: nutrition, physical activity, psychological status, environmental conditions, microbiome, and drugs.

Plant Biotechnology Journal, EarlyView.Summary OSW‐1 is a cholestane saponin uniquely produced in Ornithogalum saundersiae and exhibits a potential antitumor activity. The enzymes responsible for OSW‐1 biosynthesis in O. saundersiae, however, remain unclear. Herein, cholesterol was confirmed to be the precursor of OSW‐1 using stable‐isotope labeling method.

Unveiling the catalytical roles of three glycosyltransferases in triterpenoid saponins in quinoa
Plant Biotechnology Journal, EarlyView.Summary Saponins constitute a class of characteristic compounds within quinoa grains. In this study, metabolomic analysis identified 20 triterpene saponins, the majority of which were exclusively localized within the pericarp. Furthermore, three crucial glycosyltransferases were identified in quinoa.

Plant Biotechnology Journal, EarlyView.ABSTRACT Nitrogen availability remains a principal constraint to crop productivity. Plants cannot directly assimilate the abundant nitrogen available in our atmosphere; instead, they rely on the uptake of inorganic forms of nitrogen, such as ammonium and nitrate from the soil.
