To evaluate the role of capsular polysaccharide (CPS) as a virulence factor, the interaction of V. vulnificus with mouse peritoneal macrophages and serum, which are involved in the clearance of bacteria from blood and other tissues, were examined. In this study, MO6-24/0 (wild strain; hemolysin- and capsule-positive), MO6-24/I' (acapsular spontaneous mutant), CVD 752 (acapsular transposon mutant), and CVD 707 (hemolysin-negative and capsule-positive mutant) were used. The strain with CPS (MO6-24/0 and CVD 707) were more resistant to phagocytosis by mouse peritoneal macrophages compared with acapsular strains (MO6-24/T and CVD 752), and the resistance to phagocytosis was not changed by serum opsonin in the capsular strains. Acapsular strains were more susceptible to serum bactericidal activity than the capsular strains through the classical complement pathway. MO6-24/0 strain were detected in blood, spleen, liver and lung at 4 hours after intraperitoneally infection, whereas CVD 752 were not detected. All tested strains could induced the transcription of inflammatory cytokine gene such as IL-1, IL-6, IL-10 and TNF-u, and their inductions were not decreased by cytochalasin B treatment. This results demonstrate that CPS of V. vulnificus plays an important role in V. vulnificus infection through interfering nonspecific host defense system such as blood clearance and phagocytosis.

Purpose: The purpose of this study was to investigate the effects of uncertainty and spousal support on infertility-related quality of life in women undergoing assisted reproductive technologies. Methods: In this correlational survey study, 172 infertile women undergoing assisted reproductive technologies for infertility treatment at M hospital in Suwon participated. Data collection took place at the outpatient department of M hospital using a self-report questionnaire from July to August 2019. Data were analyzed using SPSS for Windows version 28.0. Results: The mean scores for uncertainty, spousal support, and infertility-related quality of life were 28.35 (out of 50), 86.67 (out of 115), and 57.98 (out of 100), respectively. Infertility-related quality of life was positively correlated with spousal support and negatively correlated with uncertainty. According to the regression analysis, infertility-related quality of life was significantly affected by uncertainty, total number of assisted reproductive technology treatments, marriage duration, subjective health status, the financial burden of infertility testing, and the presence of a burdensome person. These variables had an explanatory power of 35.0% for infertility-related quality of life. Conclusion Uncertainty was an important factor influencing infertility-related quality of life among women undergoing assisted reproductive technologies. It is necessary to develop and implement a nursing intervention program focused on reducing various forms of uncertainty during assisted reproductive procedures and to consider other factors affecting infertility-related quality of life in the clinical setting.

Matrix metalloproteinase 2 (MMP2) is a potent protumorigenic, proangiogenic, and prometastatic enzyme that is overexpressed in metastatic cancer. Although there have been various studies on the MMP2 gene, further studies of regulatory factors are required to achieve inhibition of MMP2 enzyme activities. MicroRNAs (miRNAs) play key roles in tumor metastasis. However, the specific functions of miRNAs in metastasis are unclear. In this study, we assessed the function of the microRNA-29 family (miR-29s) in HT1080 human fibrosarcoma cells and examined the regulatory mechanisms of these miRNAs on MMP2 activation. Using miRanda, TargetScan, and PicTar databases, miR-29s were identified as candidate miRNAs targeting MMP2. Gain-of-function studies showed that overexpression of miR-29s could inhibit the invasion of HT1080 cells, suggesting their tumor-suppressive roles in HT1080 cells. In addition, dual luciferase reporter assays indicated that miR-29s could inhibit the expression of the luciferase gene containing the 3'-untranslated region of MMP2 mRNA. Ectopic expression of miR-29s down-regulated the expression of MMP2. Moreover, ectopic expression of miR-29s reduced MMP2 enzyme activity. These results suggested that miR-29s could decrease the invasiveness of HT1080 cells by modulating MMP2 signaling. Taken together, our results demonstrated that miR-29s may serve as therapeutic targets to control tumor metastasis.
