The objective of this in vitro study was to introduce antibacterial properties to standard paper towel surfaces by coating them with selenium nanoparticles. Scanning electron microscopy was used to measure the size and distribution of the selenium coatings on the paper towels. The amount of selenium precipitated on the paper towels was measured by atomic absorption spectroscopy. In vitro bacterial studies with S. aureus were conducted to assess the effectiveness of the selenium coatings at inhibiting bacterial growth. Results showed that the selenium nanoparticles coated on the paper towel surfaces were well distributed and were semi spherical 50nm in diameter. Most importantly, the selenium nanoparticle coated paper towels inhibited S. aureus growth by 90% after 24, 48 and 72 hours compared with uncoated paper towels. Thus, this study showed that nano-selenium coated paper towels may lead to an increased eradication of bacteria to clean a more wide-range of clinical environments and for the food industry, thus, improving health.","PeriodicalId":153112,"journal":{"name":"2013 39th Annual Northeast Bioengineering Conference","volume":"418 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132442378","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, little is known about effects on bone quality during growth. Greater data exists for low calcium (Ca2+). Low-Ca (0.02%) or normal calcium and calorie-equivalent glucose or fructose diets (43%) were fed to male, 3-wk-old, B6 mice for 6 wks (4 groups; n=9/group). Weight and long-bone lengths were not affected. Low-Ca diet resulted in less stiff and strong (~40%; p<;0.01) long bone and increased toughness (energy absorption) of long-bone mid-shaft, measured by 3-point bending; post-yield displacement was increased in low Ca by >65% (p<;0.05). By histomorphometry, low Ca resulted in decreased (>20%, p<;0.05) cortical width, partially explaining the bending results. Only the glucose-fed group exhibited compensation to maintain outside circumference and diameter by increased periosteal bone formation rate (p.BFR); 3-fold greater vs. each of the other 3 groups (p<;0.05). One plausible mechanism for poor circumferential growth involves bone in a feedback loop and is suggested by decreased intestinal Ca transport and Ca transporter protein in mucosa. The fructose diet completely prevented both adaptive increases in Ca transport, and 1α-hydroxylase-mediated synthesis of 1,25(OH)2D3 levels.","PeriodicalId":153112,"journal":{"name":"2013 39th Annual Northeast Bioengineering Conference","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129266150","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}

Lee","doi":"10.1109/NEBEC.2013.4","DOIUrl":"https://doi.org/10.1109/NEBEC.2013.4","url":null,"abstract":"Although structural anisotropy is important for proper function of normal myocardium, it has been a challenge to mimic structural architecture of native tissue in vitro. Previous studies have focused on using two-dimensional cultures utilizing micropatterning of substrates. Here, we present three-dimensional (3D) decellularized engineered tissues with a controlled varying degree of extracellular matrix alignment. Engineered tissues were initially created by embedding cardiac fibroblasts in 3D collagen tissues (rat tail type I collagen, BD sciences) and cultured either under biaxial or uniaxial constraints. Biaxially constrained tissues yielded a random orientation of both cell and collagen fibers, while uniaxially constrained tissues showed that the cell and collagen fibers aligned parallel to the constrained direction. To facilitate cardiac fibroblast deposition of extracellular matrix, culture medium was supplemented with 5 ng/ml ascorbic acid every 3 days. Once desired structural alignment was obtained, cells were removed by decellurization treatment using CHAPS buffer followed by SDS buffer for 1 hr at 37°C with gentle agitation. Removal of cells was confirmed by DNA quantification and intact collagen fiber orientation was confirmed by confocal reflected light microscopy. This study demonstrates the feasibility of creating cell-formed structural alignment combined with decellularization technique to establish decellularized anisotropic engineered tissue, which can be used to evaluate the effects of biophysical cues on stem cell or stem cell-derived cardiomyocyte differentiation and function in vitro.","PeriodicalId":153112,"journal":{"name":"2013 39th Annual Northeast Bioengineering Conference","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116148490","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}
