Food poisoning outbreaks in schools can affect many students, causing physical and psychological damage and time and economic loss. Fecal indicator bacteria (FIB) have been used to monitor the contamination; however, the detection is time-consuming and confirms the contamination from all warm-blooded animals. Microbial source tracking (MST) is a molecular-based detection method that is host specific.

We studied if cafeteria kitchen-associated bacterial isolates can have any protective effect on E. coli O157:H7 in biofilm against extracellular polymeric substances (EPS)-degrading enzymes and sodium hypochlorite.

CrAssphage is a novel and by far the most abundant bacteriophage in the human gut and has been proposed as a human-specific microbial source tracking (MST) marker. However, its global use as a human-specific MST marker requires validation in more extensive regions. The purpose of this study was to evaluate the specificity and abundance of the human-specific MST marker crAssphage with PCR and RT-PCR assays in human and animal feces in Korea.

Therefore, this study was intended to improve the health of menopause women by using pollen, which is a natural food, not drugs and hormones. Experiment I provided the supernatant of pollen vinegar extract with oral administration using ovariectomized rats.

However, pollen is difficult to absorb because of its hard form. This study explores the use of the acid-treated acorn pollen (acorn pollen deposited in apple vinegar for 30 days).

This study examined the effects of social-media-based support on premenstrual syndrome (PMS) and physical activity among female South Korean university students. This quasi-experimental study with an equivalent-control-group pretest-posttest design randomly assigned 64 female students with PMS to the experimental or control group. The experimental group received social-media-based support through a smartphone application, text messaging, and e-mail for one menstrual cycle between September and December, 2016.

However, nursing students experience difficulties in using technology for learning. Despite the difficulties, nursing students' learning dynamics with technology in real clinical contexts is poorly understood.

The effects of aged ginseng, in comparison with white and red ginseng, on the lipid and glucose metabolism in high fat-fed mice were investigated. C57BL/6N mice were randomly divided into six dietary groups of normal control, high fat, and high fat supplemented with white, red, aged four-year old, and aged five-year old ginseng.

By introducing a cationic moiety into the oligonucleotide structure, they become capable of approaching the cell surface and also of crossing the cellular membrane. In an effort to develop cell-permeable oligonucleotides, we examined the piperazinephenyl-bearing 2'-deoxyuridine ((PP)U), which can be not only cationic but also fluorescent as a cationic monomer for cationic oligonucleotides.
