The dual nature of constraints on foreign worker participation in sports and physical activity in South Korea during COVID-19.

This study provides a different understanding of the constraints imposed by the pandemic and the official and unofficial restrictions that accompanied it. It is an empirical effort demonstrating that the pandemic's effects are not purely negative, but rather, also helped to produce positive and productive practices that draw upon both the inhibiting and enabling features of the constraints it triggered. Engaging with "productive power" in Foucault by considering constraints as practices that both inhibit and enable, the empirical goal of this paper is to explore how pandemic-related constraints on sports and physical activity prohibit foreign worker participation in sports and physical activity.

The Brown Algae Extract Ameliorates Ovariectomy-Induced Bone Loss in Rats and Suppresses Osteoclastogenesis through Downregulation of NFATc1/c-Fos.

Osteoporosis is characterized by reduction in bone mass and microarchitectural deterioration of the bone, which causes bone fragility and fracture susceptibility. , a brown alga, reportedly affects osteoblast differentiation. However, its protective effect on estrogen deficiency-induced bone loss has not been elucidated.

A Rare Case of Fatal Endobronchial Mucormycosis Masquerading as Endobronchial Tuberculosis.

Pulmonary mucormycosis is a relatively rare but often fatal opportunistic fungal infection that occurs mostly in immunocompromised patients. Endobronchial mucormycosis, a distinct clinical form of pulmonary mucormycosis, is very rare, and only a few cases have been reported. The most common bronchoscopic findings in patients with endobronchial mucormycosis are stenosis, erythematous mucosa and airway obstruction.

Life-Threatening Thrombocytopenia Following Intravenous Contrast Media Infusion.

Radiocontrast media-induced acute severe thrombocytopenia is a very rare complication and potentially life-threatening. Here, we report the case of a 63-year-old male patient with severe acute thrombocytopenia following first exposure to intravenous non-ionic contrast media without immediate allergic reactions. His platelet count dropped from 107000/μL to 2000/μL after six hours of radiocontrast infusion.

ethanol extract suppresses fat accumulation by down-regulating adipogenic transcription factors in mice model.

The purpose of this study was to determine the anti-obesity effects of extract (GAE) in the C57BL/6J- mice. The mice were fed GAE at 0.5% for 4 weeks, after which body weight, epididymal adipose tissue weight, plasma triglycerides, and hepatic lipid accumulation were significantly reduced in GAE-fed mice compared with control mice.

A Case of Endovascular Treatment of Severe Graft Limb Kinking after Endovascular Abdominal Aortic Aneurysm Repair.

Endovascular aneurysm repair (EVAR) has been recommended as an alternative to open aneurysm repair. The risk of severe perioperative complications is lower than that in open surgical repair; however, late complications are more likely. After EVAR, regular yearly surveillance by duplex ultrasonography or computed tomography is recommended.

6,6'-Bieckol protects insulinoma cells against high glucose-induced glucotoxicity by reducing oxidative stress and apoptosis.

Pancreatic β cells are highly sensitive to oxidative stress, which might play an important role in β cell death in diabetes. The protective effect of 6,6'-bieckol, a phlorotannin polyphenol compound purified from Ecklonia cava, against high glucose-induced glucotoxicity was investigated in rat insulinoma cells. High glucose (30 mM) treatment induced the death of rat insulinoma cells, but treatment with 10 or 50 μg/mL 6,6'-bieckol significantly inhibited the high glucose-induced glucotoxicity.

Comparison of Surgical Outcomes according to Suturing Methods in Single Port Access Laparoscopic Myomectomy.

Objectives: This study was performed to consider the clinical experience of surgical outcome of single port access (SPA) laparoscopic myomectomy according to suturing methods.

Methods: The authors operated with 2 suturing method in SPA laparoscopic myomectomy for 246 patients and compared the surgical outcomes.

Results: The some significant difference of surgical outcome according to two suturing methods was demonstrated.

Phlorofucofuroeckol A isolated from Ecklonia cava alleviates postprandial hyperglycemia in diabetic mice.

This study was designed to investigate whether phlorofucofuroeckol A inhibited α-glucosidase and α-amylase activities and alleviated postprandial hyperglycemia in diabetic mice. Phlorofucofuroeckol A that was isolated from Ecklonia cava (brown algae) demonstrated prominent inhibitory effects against α-glucosidase and α-amylase activities. The IC50 values of phlorofucofuroeckol A against α-glucosidase and α-amylase were 19.

6,6'-bieckol isolated from Ecklonia cava protects oxidative stress through inhibiting expression of ROS and proinflammatory enzymes in high-glucose-induced human umbilical vein endothelial cells.

Hyperglycemia-induced oxidative stress accelerates endothelial cell dysfunctions, which cause various complications of diabetes. The protective effects of 6,6'-bieckol (BEK), one of phlorotannin compound purified from Ecklonia cava against high-glucose-induced oxidative stress was investigated using human umbilical vein endothelial cells (HUVECs), which is susceptible to oxidative stress. High glucose (30 mM) treatment induced HUVECs' cell death, but BEK, at concentration 10 or 50 μg/ml, significantly inhibited the high-glucose-induced cytotoxicity.

Daidzein inhibits carbohydrate digestive enzymes in vitro and alleviates postprandial hyperglycemia in diabetic mice.
