Preventive and ameliorative effects of potato exosomes on UVB‑induced photodamage in keratinocyte HaCaT cells.

Exosomes isolated from potato () exhibit the biophysical characteristics of exosomes observed in mammalian cells and microorganisms, as determined by dynamic light scattering analysis and transmission electron microscopy. In the present study, it was shown that potato exosomes (ExoPs) can penetrate keratinocyte HaCaT cells, as determined by confocal microscopy and flow cytometry. In addition, ExoPs can suppress the expression of the collagen‑destroying enzymes MMP1, 2 and 9, and the inflammatory cytokines IL6 and TNF‑α, while inducing the expression of glutathione S‑transferase α 4, a cellular detoxifying enzyme, as revealed by reverse transcription‑quantitative PCR.

Trends in Serum Lipid Profiles Among Korean Adolescents, 2007-2018.

Purpose: An adverse lipid profile in adolescence often persists into adulthood, resulting in cardiovascular disease. We aimed to investigate the trends in the prevalence of adverse lipid profiles among Korean adolescents from 2007 to 2018.

Patients And Methods: The data were obtained from 9044 adolescents aged 10-19 years who participated in the Korean National Health and Nutrition Examination Surveys (KNHANES) from 2007 to 2018.

Application of an electric field for pretreatment of a seeding source for dark fermentative hydrogen production.

In present study, an electric field was newly adopted as a pretreatment method for inoculum preparation in dark fermentative hydrogen production. Various voltages (5-20 V for 10 min) were applied, and the feasibility and efficiency of this method were compared with those of heat pretreatment (90°C for 20 min). Both the highest H2 yield, 1.
