Effects of short-term exposure to printing shop particles on inflammatory responses and DNA damage in healthy young adults.

Considering the increasingly demand for printing in daily life, more attention should be paid to the health risks of printer emissions to consumers. This study designed a two-stage cross-over study with 20 volunteers to investigate whether the short-term exposure to printing shop particles (PSPs) could cause inflammatory responses and genetic damage in healthy young volunteers. According to the study, short-term exposure to high level of PSPs caused the elevation of eotaxin and TNF-α levels in serum, indicating PSPs exposure led to the inflammation in healthy subjects.

Characterization of titanium dioxide nanoparticles in confectionary products and estimation of dietary exposure level among the Chinese population.

Titanium dioxide (TiO) is widely used in the food industry. Recently, European Commission has banned TiO as a food additive, raising public concern about its health risk, especially the nanoparticles (NPs) contained therein. This study aimed to reveal the existence of TiO NPs in food and further estimate the dietary exposure level among Chinese population by characterizing particle size distribution, determining Ti content and micro-distribution in food products, and calculating food consumption from the China Health and Nutrition Survey (CHNS).

Effects of A-type oligomer procyanidins on protein glycation using two glycation models coupled with spectroscopy, chromatography, and molecular docking.

Non-enzymatic glycation of proteins can produce advanced glycation end products (AGEs) and important intermediates (α-dicarbonyl compounds such as methylglyoxal), which have potential health risks due to their association with diabetes complications. Therefore, it is of great significance to search for effective inhibitors on protein glycation. In this study, the anti-glycation potential of different kinds of A-type procyanidins was investigated by spectroscopy, chromatography and molecular docking.

Comprehensive analysis of the anti-glycation effect of peanut skin extract.

Advanced glycation end-products (AGEs) are produced during protein glycation and associated with diabetic complications. Peanut skin is rich in procyanidins, which may be used as an inhibitor of glycation. This study evaluated the potential anti-glycation effect of peanut skin extract (PSE) and dissected the underlying mechanism.
