This paper presents a powerful video surveillance system that can automatically detect a flame after the target has been captured by the camera. Due to the increased number of web-cameras being installed in many locations, the flame, with its own visible characteristics has a lot of potential research interests in safety protection services.When a flame scenario occurs, the corresponding input video frame will be marked by a rectangle which covers the flame area after being analyzed by the system. Further to this research the detection algorithms and methods will be more robust and this system allows for the classification of the type of fuel that is burning. Our research contributions are towards the development of an almost real-time flame detection system to aid with fire safety precautions in all kinds of environments with appropriate storage of these fire scenario pictures in a fixed file for further exploration of these flame features

Aims: Long noncoding RNA have been proved as important regulator in various diseases. NRON was a newly identified tumor-related lncRNA, and previous studies have reported its function in hepatocellular carcinoma and heart failure. However, the function and mechanism of lncRNA NRON in osteosarcoma still unknown. Methods: Cell proliferation, invasion, migration and apoptosis were detected via CCK-8, transwell assay and Western. Bioinformatics analysis was used to predict the potential target of NRON. Rescue experiment was performed to identify the relationship between NRON and MVB12B. Results: The expression of lncRNA NRON was significantly downregulate in osteosarcoma tissues and cell lines. Knockdown of NRON promoted cell proliferation, invasion and EMT. Overexpression of NRON inhibited cell proliferation, invasion and EMT. Bioinformatics analysis predicted that MVB12B was the direct target. The expression of MVB12B was significantly upregulated in osteosarcoma tissues and cell lines. Rescue experiment further confirmed the relationship between NRON and MVB12B. Overexpression of MVB12B completely reversed the function of NRON. Conclusion: Taken together, our results comprehensively analyzed the function of NRON in osteosarcoma and provided possible mechanism that NRON inhibited osteosarcoma development by regulating MVB12B. Thus, our study may offer a potential therapeutic target for treating osteosarcoma.

Background: Various bisphosphonate agents have been proven to be effective in preventing bone loss and fracture in osteopenic postmenopausal women. This study was designed to compare the effectiveness of various BPs on preventing the loss of bone mineral density (BMD) for postmenopausal women with osteopenia.Methods: PubMed, EMBASE, and Cochrane Central Register of Controlled Trials were screened up to identify randomized controlled trails comparing effectiveness of BPs or placebo on the BMD of postmenopausal women with osteopenia. Network metaanalysis and standard pair-wise meta-analyses were performed. The main outcomes include the percentage changes of 6-, 12-, 24-, and 36-month BMD at lumbar, total hip and femoral neck, and frequencies of new fractures and severe adverse events.Results: Fourteen randomized controlled trials were eligible, involving 11,540 participants. No significant difference was presented among the available interventions for the 6-month BMD at 3 different sites, but the magnitudes of differences among the treatment regimens became gradually increased along with the extending of follow-up periods. Daily aledronate of more than 5 mg provided the maximal percentage increase on BMD of femoral neck and lumbar spine, while zoledronate provided maximal change on BMD of total hip, at different follow-up periods. This network meta-analysis also demonstrated similar frequencies of new clinical fractures and severe adverse events among different interventions. Conclusions: A ranking spectrum depicting the effectiveness on BMD percentage change following interventions with different bisphosphonate regimens was provided. Generally, regimens with zoledronate and aledronate were found to be the most effective interventions in the 3 sites at different end points.
