However, the conventional alarm signals are badly designed and always non-specific which can not provide clear information for caregiver to make decision immediately. Therefore, the intelligent alarm system that we try to develop is to provide clear information from analyzing more sophisticated data from ventilator to help caregiver aware the clinical condition and perform the appropriate procedure at the right moment. The high pressure alarm which is one of the most frequent alarm shooting in the intensive care unit (ICU), includes the warning of airway narrowing, sputum impaction, poor lung compliance and more critical conditions. We used simulated condition to test the intelligent alarm system we develop which staff needs immediate management including alert of sputum suction, tubing disconnection and leakage in the mechanical ventilation. The result presents the suction alarm occurs when Ppeak increase, Rexp increase and Fexp decrease in the mechanical ventilation model after simulated sputum injection. The low airway leak alarm occurs when end-PEEP value less than initial PEEP setting. The larger airway leak alarm occurs when both PEEP value and expiratory tidal volume down to zero in the mechanical ventilation. It suggests that intelligent system can provide alarm decision and contribute patient safety.","PeriodicalId":6374,"journal":{"name":"2012 International Conference on Biomedical Engineering and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77685214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, PHBV is associated with disadvantages including high brittleness, slow degradation, high hydrophobicity, and unsatisfactory biocompatibility. In previous study, we improved the properties of PHBV by blending it with Ecoflex, a synthetic biopolyester with a high flexibility, fast degradation, and comparatively higher hydrophilicity. In vitro cell culture also showed significantly improved adhesion and proliferation of human bone marrow stroma cells with the introduction of Ecoflex. In this study, we sought to investigate the proliferation of periodontal ligament stem cells (PDLSCs) and periosteum-derived stem cells (PC) on electro spun PHBV-Ecoflex mats. PHBV was co dissolved with Ecoflex in dichloromethane at different mass ratios (PHBV/Ecoflex: 100/0, 70/30, 50/50, 30/70) and electro spun into mats. The cell proliferation of hPDLSCs and hPCs displayed almost the same rules on different mats. The cell number on any Ecoflex-containing mat was higher than that on the pure PHBV mat at all time points. The cell number increased with the Ecoflex concentration in the mat. So we suppose that PHBV-Ecoflex mats could be used in periodontal regeneration.","PeriodicalId":6374,"journal":{"name":"2012 International Conference on Biomedical Engineering and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79922714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, as an important angiogenic factor, the effect of Angiopoietin-1 (Ang-1) in the process of mouse ovary angiogenesis is still not defined in detail so far. The aim of this study was to examine the expression and regulation of Ang-1 in mouse ovary during sexual maturation, follicular development induced by eCG, ovulation induced by hCG and corpus luteum formation and regression by reverse transcription polymerase chain reaction (RT-PCR). The results showed that Ang-1 mRNA expression level was lower on days 10 and 20 after birth, but it was sharply increased on day 25 after birth, while generally decreased. Ang-1 mRNA expression reached the peak level at 48 hours after injection of eCG. At 3, 5 and 9 hours after injection of hCG, Ang-1 mRNA expression decreased, while at 0.5 and 7 hours after injection of hCG, Ang-1 mRNA expression level was higher. Ang-1 mRNA was expressed on days 1-15 after injection of hCG, and Ang-1 expression increased gradually on days 5-15 after injection of hCG, while Ang-1 expression level reached maximum on day 15 after injection of hCG. These results suggest that Ang-1 may play a role during the process of mouse follicular development, ovulation and corpus luteum formation and regression.","PeriodicalId":6374,"journal":{"name":"2012 International Conference on Biomedical Engineering and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79367256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A major concern is that repeated administration to patients often leads to undesirable antidrug antibodies with a wide range of life threatening consequences that induce immunogenicity or an adverse response of the immune system. The antibodies are generally thought triggered by the tendency of monomer protein molecules to aggregate, although why aggregation occurs is not known. In protein deposition diseases such as Alzheimer and Parkinson, protein aggregates have stronger immunogenicity. Typically, the aggregates known to elicit immunogenicity are globular proteins having molecular weights from 6-100 kDa and diameters from 3-10 nm that are comparable to inanimate natural or manmade nanoparticles that have been linked to damage of deoxyribonucleic acid by the natural emission of low-level ultraviolet radiation induced by quantum electrodynamics. Similarity suggests the protein aggregates form as monomers cross-link under ultraviolet radiation produced by nanoparticles of the aggregates themselves. How immunogenicity may be reduced is discussed.","PeriodicalId":6374,"journal":{"name":"2012 International Conference on Biomedical Engineering and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85761479","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
