Superoxide dismutase (SOD) and Coenzyme Q10 (CoQ10) are prominent antioxidants known to mitigate oxidative damage. (2) Methods: This study recruited 86 patients undergoing in vitro fertilization (IVF) at a single center for a 12-week, randomized, double-blind, active-comparator-controlled trial.

Quantify ED nursing subjective workload and explore the impact of work experience on perceived workload.
Methods: Thirty-two ED nurses at a tertiary academic hospital in the Republic of Korea were surveyed to assess their subjective workload for ED procedures using the National Aeronautics and Space Administration Task Load Index (NASA-TLX).
The coronavirus disease 2019 (COVID-19) outbreak caused by SARS-CoV-2 (severe acute respiratory syndrome coronavirus-2) has affected various medical fields worldwide. However, relatively few studies have examined the impact of COVID-19 infection and vaccination on in vitro fertilization (IVF) outcomes and changes in SARS-CoV-2 antibody concentration in follicular fluid (FF). A total of 45 women were prospectively recruited and assigned to 3 groups: uninfected and non-vaccinated control group (Control group), infected group (COVID + group), and vaccinated group (Vaccination group).

Early diagnosis of NCRHP and laparoscopic resection is important to prevent catastrophic conditions. However, delayed diagnosis until the second or third trimester makes it difficult to accurately diagnose between NCRHP and bicornuate uterine pregnancy, as both conditions present uterine rupture and massive hemoperitoneum.

However, this new species is distinguished from its congeners by the position and size of dorsal projection.

To better understand the underlying mechanisms of these cancers and identify potential therapeutic targets, we analyzed publicly accessible Cancer Genome Atlas datasets of COAD and LIHC. Our analysis revealed that differentially expressed genes (DEGs) during early tumorigenesis were associated with cell cycle regulation.

One candidate is CR6-interacting factor1 (CRIF1), which controls translation and membrane insertion of 13 mitochondrial proteins involved in oxidative phosphorylation. Here, we found that CRIF1 mRNA and protein expression were significantly reduced in postmortem brains of elderly PD patients compared to normal controls.

This study tested an integrated model of language development within a longitudinal data set of 1,894 socioeconomically diverse Korean children (48.35% girls; > 99% native-born Korean citizens) from the first year of life (age 3-8 months) to ages 3 and 6 years.

Despite being of significant concern for patients, the intraoperative pain and discomfort has not been of great interest to retinal surgeons or researchers. This randomized controlled trial evaluated the effect of a 3-day novel structured exercise on reducing musculoskeletal pain from the face-down posture in 61 participants (31 in the exercise group) who underwent vitrectomy.

Aim: The present study investigates the procedure-related fetal loss rate and obstetrical outcomes of selective feticide in dichorionic twins.
Methods: We retrospectively analyzed the data of 44 cases of dichorionic twins. Two different indications for selective feticide were set: (i) the presence of genetic or congenital anomaly; and (ii) an obstetrical indication specified as a past maternal history of preterm delivery that caused fetal death or cerebral palsy of the child.
The aim of this study was to evaluate the effects of marinade under different conditions (temperature and vacuum) on pork ham cooked by the sous-vide method (61°C and 98.81% vacuum for 45 min). Control group was non-marinade pork ham.

A Korean traditional sourdough was made by fermenting rice flour with rice wine (makgeolli) and used to make sponge-like bread (jeung-pyun). The aim of this study was to investigate the microbial diversity of makgeolli products and their influence on the organoleptic quality of jeung-pyun.

Probiotic bacteria must have not only tolerance against bile salt but also no genes for antibiotic resistance. Leuconostoc citreum is a dominant lactic acid bacterium in various fermented foods, but it is not regarded as a probiotic because it lacks bile salt resistance. Therefore, we aimed to construct a bile salt-resistant L.

LAOS were prepared from LAR by enzymatic hydrolysis with endo-arabinanase from Bacillus licheniformis, followed by removal of the arabinose fraction by incubation with resting cells of Leuconostoc mesenteroides. The resulting LAOS contained DP2 (28.

To expand our understanding of the species, we generated a draft genome sequence of the strain and analyzed its genomic features related to the aforementioned probiotic properties. Genome assembly resulted in 35 contigs, and the draft genome has 1,688,202 base pairs (bp) with a G+C content of 43.
