Question: Elevated levels of EMMPRIN/CD147 in cancer tissues have been correlated with tumor progression but the regulation of its expression is not yet understood. Here, the regulation of EMMPRIN expression was investigated in testicular germ cell tumor (TGCTs) cell lines.', 'EMMPRIN expression in seminoma JKT-1 and embryonal carcinoma NT2/D1 cell lines was determined by Western blot, immunofluorescence and qRT-PCR. Membrane vesicles (MVs) secreted from these cells, treated or not with EMMPRIN siRNA, were isolated by differential centrifugations of their conditioned medium. MMP-2 was analyzed by zymography and qRT-PCR.', 'The more aggressive embryonic carcinoma NT2/D1 cells expressed more EMMPRIN mRNA than the seminoma JKT-1 cells, but surprisingly contained less EMMPRIN protein, as determined by immunoblotting and immunostaining. The protein/mRNA discrepancy was not due to accelerated protein degradation in NT2/D1 cells, but by the secretion of EMMPRIN within MVs, as the vesicles released from NT2/D1 contained considerably more EMMPRIN than those released from JKT-1. EMMPRIN-containing MVs obtained from NT2/D1, but not from EMMPRIN-siRNA treated NT2/D1, increased MMP-2 production in fibroblasts to a greater extent than those from JKT-1 cells.

Question: To compare rates of pelvic inflammatory disease (PID) among women who did and did not receive an intrauterine device (IUD) the day they sought emergency contraception (EC) or pregnancy testing.', 'Women, 15 to 45years of age, who sought EC or pregnancy testing from an urban family planning clinic completed surveys at the time of their clinic visit (August 22, 2011, to May 30, 2013) and 3 months after their clinic visit. The surveys assessed contraceptive use and symptoms, testing, and treatment for sexually transmitted infections (STI) and PID. We reviewed the medical records of participants who reported IUD placement within 3months of enrollment and abstracted de-identified electronic medical record (EMR) data on all women who sought EC or pregnancy testing from the study clinic during the study period.', 'During the study period, 1,060 women visited the study clinic; 272 completed both enrollment and follow-up surveys. Among survey completers with same-day IUD placement, PID in the 3months after enrollment was not more common (1/28 [3.6%]; 95% CI, 0%-10.4%) than among women who did not have a same-day IUD placed (11/225 [4.9%]; 95% CI, 2.7%-8.6%; p=.71). Chart review and EMR data similarly showed that rates of PID within 3months of seeking EC or pregnancy testing were low whether women opted for same-day or delayed IUD placement.

Question: Isorhamnetin (Isor), a 3-O-methylated metabolite of quercetin, has shown antioxidant and anti-proliferative effects in previous studies. In this study, we investigated the anti-inflammatory effect of Isor on LPS-induced acute lung injury (ALI). Accordingly, we evaluated the effect of Isor on cytokine production elevated by LPS (1g/ml) in vitro. An in vivo ALI murine model was also established via lipopolysaccharide inhalation (LPS, 20mg/kg), and the cytokine levels and inflammatory cell count in bronchoalveolar lavage fluid (BALF) were evaluated. The observed lung injury was assessed using histopathologic sections via H&E straining. Furthermore, to investigate whether the anti-inflammatory effect of Isor is associated with NF-B and MAPKs pathway activation, the phosphorylated levels of ERK, JNK, IBa and NF-B(p65) were determined.', 'Isor significantly inhibited LPS-induced TNF-, IL-1 and IL-6 secretion both in vitro and in vivo. Neutrophil infiltration and edema in an ALI model were substantially alleviated. The histopathological changes induced by LPS were lessened by Isor. Additionally, Isor notably suppressed the phosphorylation of ERK, JNK, IBa and NF-B(p65) activated by LPS in vivo.
