1-/-; Gpx3-/- mice at 4 months but decreased at 8 and 12 months. There was no change in β-catenin and its targets associated with Wnt signaling. Increased ROS and decreased SOD activity were observed in Nkx3.1-/-; Gpx3-/- mice at 12 months of age. The histopathologic score and epithelium thickness were increased, and lumen area was decreased in Gpx3 knockout mice. Discussion and conclusions Gpx3 loss increased the hyperplasia of PIN in the pre-cancerous stage of the prostate. Loss of Gpx3 induced oxidative stress. Histopathologically, no invasive carcinoma was identified, and Gpx3 loss did not increase Wnt/β-catenin signaling. Further research on the role of GPX3 in the transition of PIN to invasive carcinoma is needed. We show, for the first time, that the antioxidant enzyme GPX3 plays a vital role in inhibiting hyperplasia in the PIN stage of the prostate gland in vivo.Purpose To determine nurses' challenges, extent of involvement, and the impact of involvement in politics and policy making. Organizing construct Nurses in politics and health policy making. Methods Literature was searched in PubMed, Scopus, Google Scholar, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), OVID, and Open Grey using phrases comprising the following key words "nurses", "policy making", "politics", "health policy", "nurses involvement in policy making/politics/health policy", "nurses challenges in policy making/politics/policy", and "impact of nursing policy making/politics/health policy"; 22 articles published from January 2000 to May 2019 were included. Findings The major challenges included intra- and interprofessional power dynamics, marginalization of nurses in policy making, and nursing profession-specific challenges. The extent of involvement was inadequate, and nurses mainly worked as policy implementers rather than as policy developers. Those nurses who participated in policy development focused on health promotion to build healthy communities and to empower nurses and the nursing profession. Conclusions Nurses' involvement in policy making has not improved over time. Nursing institutions and regulatory bodies should prepare and encourage nurses to work as policymakers rather than implementers and advocate for the rightful place of nurses at policy-making forums. Clinical relevance Preparation for health system policy making starts in the clinical settings. Educational institutions and nurse leaders should adequately prepare nurses for policy making, and nurses should participate in policy making at the organization, system, and national levels.Background & aims Ferroportin disease (FD) and hemochromatosis type 4 (HH4) are associated with variants in the ferroportin-encoding gene SLC40A1. Both phenotypes are characterized by iron overload despite being caused by distinct variants that either mediate reduced cellular iron export in FD or resistance against hepcidin-induced inactivation of ferroportin in HH4. The aim of this study was to assess if reduced iron export also confers hepcidin resistance and causes iron overload in FD associated with the R178Q variant. Methods The ferroportin disease variants R178Q andA77D and the HH4-variant C326Y were overexpressed in HEK-293T cells and subcellular localization was characterized by confocal microscopy and flow cytometry. Iron export and cytosolic ferritin were measured as markers of iron transport and radioligand binding studies were performed. The hepcidin-ferroportin axis was assessed by ferritin/hepcidin correlation in patients with different iron storage diseases. Results In the absence of hepcidin, the R178Q and A77D variants exported less iron when compared to normal and C326Y ferroportin. Doramapimod datasheet In the presence of hepcidin, the R178Q and C326Y, but not the A77D-variant, exported more iron than cells expressing normal ferroportin. Regression analysis of serum hepcidin and ferritin in patients with iron overload are compatible with hepcidin deficiency in HFE hemochromatosis and hepcidin resistance in R178Q FD. Conclusions These results support a novel concept that in certain FD variants reduced iron export and hepcidin resistance could be interlinked. Evasion of mutant ferroportin from hepcidin-mediated regulation could result in uncontrolled iron absorption and iron overload despite reduced transport function.Background Accumulating long noncoding RNAs (lncRNAs) have been recognized to participate in glioma development. Nevertheless, knowledge of the role of linc00294 in glioma remains incomplete. Methods Bioinformatics analysis predicted the differential expression of LINC00294 and neurofilament medium (NEFM) in tumors and normal tissues, as well as the binding between LINC00294 and miR-1278, miR-1278 and NEFM. Luciferase and RNA immunoprecipitation assays were used for the verification of interactions. The potential role of LINC00294 in glioma development was investigated using functional assays, singly and in parallel with its interplay with miR-1278 and NEFM. Cell counting kit-8 and EdU assays were applied to measure cellular proliferation, whereas the terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) method was employed to detect apoptosis. Results A new lncRNA, LINC00294, was highly expressed in normal brain tissues. However, it was markedly down-regulated in GBM tissues and glioma cell lines. Overexpression of LINC00294 abates glioma cell proliferation but induces apoptosis. Meanwhile, tumor suppressor NEFM was revealed to be distinctly diminished in cancerous conditions and enhanced in glioma cells by LINC00294 up-regulation. Interactions of miR-1278 with LINC00294 or NEFM occur, and the expression of NEFM is up-regulated by LINC00294 through their competition with respect to binding to miR-1278. Finally, the rescue assays further confirmed that LINC00294 inhibits glioma cell proliferation by absorbing miR-1278 to enhance NEFM. Conclusions Collectively, our observations demonstrate the tumor-suppressive function of LINC00294 in glioma development by sponging miR-1278 and promoting NEFM, suggesting a potential use in therapy for glioma.Background/aim In order to enrich epidemiological knowledge regarding traumatic dental injuries (TDI) in China, and to further improve the treatment, prevention and education of TDI, the aim of this study was to retrospectively analyze the TDI that presented to the emergency dental department at the Stomatological Hospital in Xi'an, China. Methods This retrospective study included all first-visit patients who presented with TDI at the Stomatological Hospital affiliated with the Fourth Military Medical University in Xi'an, China, between January 2013 and June 2019. Data were extracted using the terms of diagnosis of TDI from the hospital database. Results Overall, 965 (606 males and 359 females) files were reviewed. The average age was 22.8 ± 13.4 years. Among the 2059 teeth injured (average of 2.1 teeth per patient), the maxillary incisors (1751; 85.0%) were the most prevalent teeth to present with injuries, while the main types of injuries were concussions (14.8%) enamel-dentin-fractures (14.50%) and enamel-dentin-pulp fractures (14.
