    Filling materials (cement-based calcium hydroxide, amalgam, glass ionomer and IRM) are often used as sealers. However, none of them meets the desirable characteristics of a suitable sealing material. This study aims to characterize the new sealer, MTA/HAp from the incorporation of 5% by weight of synthetic hydroxyapatite to the MTA and to investigate the influence of the addition of HAp on the characteristic structural, chemical and consistency of the MTA. For this, we used MTA Angelus ® and HAp synthesized in the laboratory. We used the ratio by mass 95%MTA/5%HAp, where the hydroxyapatite added the characteristic of the MTA osteoconduction. The tests were performed: XRD, XRF and consistency. The results showed that both the new cement had the same crystalline phases as the same chemical composition of its precursors, yet having suitable consistency (plastic mass) of a sealer as well as the pure MTA.

  19. MTA3 regulates CGB5 and Snail genes in trophoblast

    International Nuclear Information System (INIS)

    Highlights: •Impaired MTA3, raised CGB5 and Snail expression are associated with preeclampsia. •Knock-down of MTA3 causes up-regulation of CGB5 and Snail genes in BeWo cells. •MTA3 occupies CGB5 and Snail gene promoters in BeWo cells. -- Abstract: Secreted by the placental trophoblast, human chorionic gonadotropin (hCG) is an important hormone during pregnancy and is required for the maintenance of pregnancy. Previous studies have shown that dys-regulation of hCG expression is associated with preeclampsia. However, the exact relationship between altered hCG levels and development of preeclampsia is unknown. Metastasis associated protein 3 (MTA3), a chromatin remodeling protein, is abundantly expressed in the placental trophoblasts, but its function is unknown. In breast cancer, MTA3 has been shown to repress the expression of Snail and cell migration. However, whether MTA3 acts similarly in the trophoblast has not been investigated. In the present study, we examined the role of MTA3 in regulating the hCG β-subunit gene (gene name: CGB5) and Snail expression in the trophoblast cell line, BeWo, as well as its relevance to the high hCG expression levels seen in preeclampsia. First, we investigated MTA3 expression in preeclamptic placenta as compared to normal control placenta via gene expression microarray and qRT-PCR and found that MTA3 was significantly down-regulated, whereas both CGB5 and Snail were up-regulated in preeclamptic placenta. Secondly, we knocked down MTA3 gene in trophoblast cell line BeWo and found Snail and hCG were both up-regulated, suggesting that MTA3 represses Snail and hCG gene expression in trophoblasts. Next, we cloned the CGB5 and Snail promoters into the pGL3-basic vector individually and found that silencing of MTA3 by siRNA resulted in an increase of both CGB5 and Snail promoter activities. To confirm that this MTA3 inhibition is a direct effect, we performed a chromatin immune-precipitation (ChIP) assay and found that MTA3

Optimal properties of Pro Root MTA in in-vitro and in-vivo studies has been proven. On the other hand, based on some studies, Root MTA (Iranian Pro Root MTA and Portland cement are similar to Pro Root MTA in physical and biologic properties. The aim of this study was to evaluate bacterial leakage (amount and mean leakage time of four root- end filling materials. Materials and Methods: In this experimental in-vitro study, seventy six extracted single- rooted human teeth were randomly divided into six groups for root-end filling with gray Pro Root MTA, white Pro Root MTA, Root MTA (Iranian Pro Root MTA, Portland Cement (type I and positive and negative control groups. Root canals were instrumented using the step- back technique. Root- end filling materials were placed in 3mm ultra sonic retro preparations. Samples and microleakage model system were sterilized in autoclave. The apical 3-4 mm of the roots were immersed in phenol red with 3% lactose broth culture medium. The coronal access of each specimen was inoculated every 24h with a suspension of Streptococcus sanguis (ATCC 10556. Culture media were observed every 24h for colour change indicating bacterial contamination for 60 days. Statistical analysis was performed using log- rank test with P<0.05 as the limit of significance. Results: At the end of study 50%, 56.25%, 56.25% and 50% of specimens filled with Gray Pro Root MTA, White Pro Root MTA. Root MTA and Portland Cement (type I had evidence of leakage respectively. The mean leakage time was 37.19±6.29, 36.44±5.81, 37.69±5.97 and 34.81±6.67 days respectively. Statistical analysis of data showed no significant difference among the leakage (amount and mean leakage time of the four tested root- end filling materials (P=0.9958.

    Single visit apexification using mineral trioxide aggregate (MTA) is a new boon in effective management of nonvital tooth with an open apex which has steadily gained popularity with clinicians; also it shortens the treatment period and improves patient compliance. Importance of this approach lies in expedient cleaning and shaping of the root canal system, followed by its apical seal with MTA. There are several case reports available describing the use of MTA as an apexification agent in incisors and premolar, but presented cases are the unique case reports demonstrating successful apexification procedure using MTA in young permanent mandibular molars. After eight-month follow-up, teeth were without any abnormal clinical symptoms; rather there were radiographic resolution of the periapical lesion and induction of root end closure with new hard tissue formation over MTA.

  7. Properties of two EBV Mta nuclear export signal sequences.

    Science.gov (United States)

    Chen, L; Liao, G; Fujimuro, M; Semmes, O J; Hayward, S D

    2001-09-15

    The Epstein-Barr virus (EBV) Mta protein is a posttranscriptional regulator of EBV lytic gene expression that affects RNA splicing and transport. Mta mediates cytoplasmic accumulation of unspliced EBV replication gene transcripts and shuttles between the nucleus and cytoplasm. Mta contains a recognized leucine-rich, putative nuclear export signal (NES) between aa 227 and 236. Deletion of this signal sequence eliminated shuttling, while mutation of the core LXL motif in the putative NES diminished but did not abolish the ability of Mta to shuttle from donor to recipient cells in a heterokaryon assay. A double mutation of the LXL motif plus an upstream VTL motif eliminated shuttling, suggesting that Mta may have two NES motifs. In confirmation of this, transfer of either the sequence encoding the leucine-rich aa 227-236 motif or that encoding the adjacent hydrophobic aa 218-227 sequence to a GFP-NLS-pyruvate kinase reporter protein conferred the property of cytoplasmic accumulation onto the heterologous protein. Cytoplasmic accumulation of both the aa 225-237 and 218-227 containing reporters was minimal in the presence of the inhibitor leptomycin B, indicating that both motifs mediated Crm-1-dependent export. Mutations in the NES signal sequences abolished the ability of Mta to mediate cytoplasmic accumulation of BALF2 replication gene transcripts. This included mutation of the LXL motif which still showed cytoplasmic shuttling, suggesting that the NES mutations might have additional effects on Mta function. Wild-type Mta co-immunoprecipitated with the splicing factor SC35 and colocalized with SC35 in transfected cells, modifying endogenous SC35 distribution within the nucleus to give more intense, rounded spots. Interestingly, the NES mutant proteins appeared to have altered interactions with the splicing complex, binding more tightly to SC35 in co-immunoprecipitation assays. These observations suggest a linkage between the splicing and export functions of Mta. PMID

  8. Structure of the corrinoid:coenzyme M methyltransferase MtaA from Methanosarcina mazei.

    Hoeppner, Astrid; Thomas, Frank; Rueppel, Alma; Hensel, Reinhard; Blankenfeldt, Wulf; Bayer, Peter; Faust, Annette

    2012-11-01

    The zinc-containing corrinoid:coenzyme M methyltransferase MtaA is part of the methanol-coenzyme M-methyltransferase complex of Methanosarcina mazei. The whole complex consists of three subunits: MtaA, MtaB and MtaC. The MtaB-MtaC complex catalyses the cleavage of methanol (bound to MtaB) and the transfer of the methyl group onto the cobalt of cob(I)alamin (bound to MtaC). The MtaA-MtaC complex catalyses methyl transfer from methyl-cob(III)alamin (bound to MtaC) to coenzyme M (bound to MtaA). The crystal structure of the MtaB-MtaC complex from M. barkeri has previously been determined. Here, the crystal structures of MtaA from M. mazei in a substrate-free but Zn(2+)-bound state and in complex with Zn(2+) and coenzyme M (HS-CoM) are reported at resolutions of 1.8 and 2.1 Å, respectively. A search for homologous proteins revealed that MtaA exhibits 23% sequence identity to human uroporphyrinogen III decarboxylase, which has also the highest structural similarity (r.m.s.d. of 2.03 Å for 306 aligned amino acids). The main structural feature of MtaA is a TIM-barrel-like fold, which is also found in all other zinc enzymes that catalyse thiol-group alkylation. The active site of MtaA is situated at the narrow bottom of a funnel such that the thiolate group of HS-CoM points towards the Zn(2+) ion. The Zn(2+) ion in the active site of MtaA is coordinated tetrahedrally via His240, Cys242 and Cys319. In the substrate-free form the fourth ligand is Glu263. Binding of HS-CoM leads to exchange of the O-ligand of Glu263 for the S-ligand of HS-CoM with inversion of the zinc geometry. The interface between MtaA and MtaC for transfer of the methyl group from MtaC-bound methylcobalamin is most likely to be formed by the core complex of MtaB-MtaC and the N-terminal segment (a long loop containing three α-helices and a β-hairpin) of MtaA, which is not part of the TIM-barrel core structure of MtaA.

    Have you ever hesitated to print a confidential document using CERN printers? Or perhaps you have rushed quickly to the printer after hitting the “print” button in order to avoid someone else getting hold of and reading your document? These times are over now with the new printing infrastructure!   Indeed, many of us regularly print out confidential documents like our salary slips, MARS forms, tendering documents and drafts of preliminary papers. The upcoming CERN data protection policy will require all of us to respect the confidentiality of such documents and, as the word “confidential” implies, access to “confidential” or sensitive documents will be tightly controlled. What can we do about the public printers located in many buildings, floors and shared spaces - accessible not only to CERN staff and users but also to visitors and guests? Some printers are located in the vicinity of restaurants, cafeterias or close to paths taken b...

    The primary objective of this study was to assess the biological effects of a new dentine substitute based on Ca₃SiO₅ (Biodentine™) for use in pulp-capping treatment, on pseudo-odontoblastic (MDPC-23) and pulp (Od-21) cells. The secondary objective was to evaluate the effects of Biodentine and mineral trioxide aggregate (MTA) on gene expression in cultured spheroids. We used the acid phosphatase assay to compare the biocompatibility of Biodentine and MTA. Cell differentiation was investigated by RT-qPCR. We investigated the expression of genes involved in odontogenic differentiation (Runx2), matrix secretion (Col1a1, Spp1) and mineralisation (Alp). ANOVA and PLSD tests were used for data analysis. MDPC-23 cells cultured in the presence of MTA had higher levels of viability than those cultured in the presence of Biodentine and control cells on day 7 (P = 0.0065 and P = 0.0126, respectively). For Od-21 cells, proliferation rates on day 7 were significantly lower in the presence of Biodentine or MTA than for control (P Biodentine and in control cells. Biodentine and MTA may modify the proliferation of pulp cell lines. Their effects may fluctuate over time, depending on the cell line considered. The observed similarity between Biodentine and MTA validates the indication for direct pulp-capping claimed by the manufacturers. PMID:23515903

    Darve, Christine; Norris, Barry; Pei, Liujin

    2006-03-01

    MuCool Test Area (MTA) is a complex of buildings at Fermi National Accelerator Laboratory, which are dedicated to operate components of a cooling cell to be used for Muon Collider and Neutrino Factory R&D. The long-term goal of this facility is to test ionization cooling principles by operating a 25-liter liquid hydrogen (LH2) absorber embedded in a 5 Tesla superconducting solenoid magnet. The MTA solenoid magnet will be used with RF cavities exposed to a high intensity beam. Cryogens used at the MTA include LHe, LN2 and LH2. The latter dictates stringent system design for hazardous locations. The cryogenic plant is a modified Tevatron refrigerator based on the Claude cycle. The implementation of an in-house refrigerator system and two 300 kilowatt screw compressors is under development. The helium refrigeration capacity is 500 W at 14 K. In addition the MTA solenoid magnet will be batch-filled with LHe every 2 days using the same cryo-plant. This paper reviews cryogenic systems used to support the Muon Collider and Neutrino Factory R&D programs and emphasizes the feasibility of handling cryogenic equipment at MTA in a safe manner.

    Full Text Available Objective: The purpose of this study was to investigate the histological response to delib-erate perforation repaired using amalgam or MTA either immediately or with delay on cats’ molars.Materials and Methods: Twenty-eight molar teeth from four cats were used in this ex-perimental randomized study. After preparing the access cavity, the floor of pulp cham-bers were deliberately perforated with a round bur No. 5. The teeth were randomly divided into four groups of seven. In groups one and two,the perforation was immediately sealed with amalgam and MTA, respectively. In groups three and four, the perforations were leftexposed to saliva for six weeks and then sealed with amalgam or MTA. The animals were sacrificed four months later and the specimens processed. The samples were blindly exam-ined for inflammatory reaction and healing process under light microscope. The data were analyzed with Mann-Whitney U and Fisher exact tests.Results: The type of the materials used has no significant effect on the severity of in-flammation; while, immediate or delayed repair of furcal perforation has, and immediate application of, MTA produced less inflammation than that of amalgam (P<0.05. No dif-ferences were found in vasodilatation, abscess formation or healing process between the immediate and the delayed repair groups (P=0.13.Conclusion: MTA is a more suitable material than amalgam for perforation repair, par-ticularly when used immediately after perforation.

  20. MTA1 regulation of ERβ pathway in salivary gland carcinoma cells

    Energy Technology Data Exchange (ETDEWEB)

    Ohshiro, Kazufumi, E-mail: bcmkxo@gwu.edu; Kumar, Rakesh

    2015-09-04

    Abstracts: Although Metastatic-tumor antigen 1 (MTA1) is differentially expressed in metastatic cancer and coregulates the status and activity of nuclear receptors, its role upon estrogen receptor β (ERβ) – a potent tumor suppressor, remains poorly understood. Here we investigated whether MTA1 regulates the expression and functions of ERβ, an ER isoform predominantly expressed in salivary gland cancer cells. We found that the depletion of the endogenous MTA1 in the HSG and HSY salivary duct carcinoma cell lines enhances the expression of ERβ while MTA1 overexpression augmented the expression of ERβ in salivary duct carcinoma cells. Furthermore, MTA1 knockdown inhibited the proliferations and invasion of HSG and HSY cells. The noted ERβ downregulation by MTA1 overexpression involves the process of proteasomal degradation, as a proteasome inhibitor could block it. In addition, both MTA1 knockdown and ERβ overexpression attenuated the cell migration and inhibited the ERK1/2 signaling in the both cell lines. These findings imply that MTA1 dysregulation in a subset of salivary gland cancer might promote aggressive phenotypes by compromising the tumor suppressor activity of ERβ, and hence, MTA1-ERβ axis might serve a new therapeutic target for the salivary gland cancer. - Highlights: • MTA1 silencing upregulates ERβ expression in salivary gland carcinoma cells. • MTA1 overexpression downregulates ERβ expression via proteasomal degradation. • Upregulation of ERβ expression inhibits cell migration and ERK signaling. • MTA1 knockdown inhibits cell proliferation and invasion.

    Introduction Microorganisms, predominantly Enterococcus faecalis are found responsible in the progression of pulpal, periradicular diseases and in endodontic failures. Unsuccessful conventional treatment might necessitate the need for a surgical approach; where in retrograde restorative materials are used to seal the apex. Among the root end filling materials, Mineral Trioxide Aggregate (MTA) is considered biocompatible and is most commonly used in clinical applications but it has limited antibacterial activity. Metallic silver and chlorhexidine have been added into various dental materials to enhance the antibacterial activity. Aim This study aimed to compare the antibacterial effect of MTA, MTA mixed with silver zeolite and MTA mixed with chlorhexidine against Enterococcus faecalis. Materials and Methods Test materials used in the study were divided into three groups namely Group 1- MTA, Group 2-MTA + Silver Zeolite, Group 3-MTA + Chlorhexidine. Direct contact test was done by placing a standardized suspension of Enterococcus faecalis on the test materials in a 96 well microtiter plate. The bacterial growth was measured spectrophotometrically using ELISA reader at intervals of one, three and seven days. Statistical Analysis Data was collected by recording the optical density and analyzed using two-way ANOVA and Tukey’s multiple post hoc test followed by paired-t test. Results and Conclusion All test groups showed antibacterial activity against Enterococcus faecalis at day one, three and seven. MTA with silver zeolite showed the maximum antibacterial activity followed by MTA with 2% chlorhexidine. The least antibacterial effect was shown by MTA mixed with sterile water.

    Parkinson disease (PD) is a neurodegenerative disorder with loss of dopaminergic neurons of the brain, which results in insufficient synthesis and action of dopamine. Metastasis-associated protein 1 (MTA1) is an upstream modulator of tyrosine hydroxylase (TH), the rate-limiting enzyme in dopamine synthesis, and hence MTA1 plays a significant role in PD pathogenesis. To impart functional and clinical significance to MTA1, we analyzed MTA1 and TH levels in the substantia nigra region of a large cohort of human brain tissue samples by Western blotting, quantitative PCR, and immunohistochemistry. Our results showed that MTA1 and TH levels were significantly down-regulated in PD samples as compared with normal brain tissue. Correspondingly, immunohistochemistry analysis for MTA1 in substantia nigra sections revealed that 74.1% of the samples had a staining intensity of <6 in the PD samples as compared with controls, 25.9%, with an odds ratio of 8.54. Because of the clinical importance of MTA1 established in PD, we looked at agents to modulate MTA1 expression in neuronal cells, and granulocyte colony-stimulating factor (G-CSF) was chosen, due to its clinically proven neurogenic effects. Treatment of the human neuronal cell line KELLY and acute 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine mouse model with G-CSF showed significant induction of MTA1 and TH with rescue of phenotype in the mouse model. Interestingly, the observed induction of TH was compromised on silencing of MTA1. The underlying molecular mechanism of MTA1 induction by G-CSF was proved to be through induction of c-Fos and its recruitment to the MTA1 promoter. PMID:27044752

    In order to investigate the roles of MTA2 in the pathogenesis of ovarian epithelial cancer, the expression of MTA2 in 4 ovarian cell lines were detected by semi-quantitative RT-PCR and Western-blot assays. MTA2 expression in normal, borderline, benign and malignant epithelial o varian tissues was immunohistochemically examined. The expression of MTA2 mRNA and protein was detected in all of 4 cell lines of ovarian epithelial cancer. The expression of MTA2 mRNA and protein was higher in strong migration cell lines than in weak migration ones. In borderline and malignant ovarian tissues tested, MTA2 staining was dramatically stronger than in normal and benign tissues (P<0.01). The expression levels in malignant ovarian tissues were significantly higher than that in borderline epithelial ovarian tissues (P<0.01). The expression of MTA2 was correlated with clinical stage, histopathological grade and lymph node metastasis. It was concluded that the high expression of MTA2 was associated with more aggressive behaviors of epithelial ovarian cancer. MTA2 provides a novel indicator of ovarian cancer.

  14. Methylthioadenosine (MTA) inhibits melanoma cell proliferation and in vivo tumor growth

    International Nuclear Information System (INIS)

    Melanoma is the most deadly form of skin cancer without effective treatment. Methylthioadenosine (MTA) is a naturally occurring nucleoside with differential effects on normal and transformed cells. MTA has been widely demonstrated to promote anti-proliferative and pro-apoptotic responses in different cell types. In this study we have assessed the therapeutic potential of MTA in melanoma treatment. To investigate the therapeutic potential of MTA we performed in vitro proliferation and viability assays using six different mouse and human melanoma cell lines wild type for RAS and BRAF or harboring different mutations in RAS pathway. We also have tested its therapeutic capabilities in vivo in a xenograft mouse melanoma model and using variety of molecular techniques and tissue culture we investigated its anti-proliferative and pro-apoptotic properties. In vitro experiments showed that MTA treatment inhibited melanoma cell proliferation and viability in a dose dependent manner, where BRAF mutant melanoma cell lines appear to be more sensitive. Importantly, MTA was effective inhibiting in vivo tumor growth. The molecular analysis of tumor samples and in vitro experiments indicated that MTA induces cytostatic rather than pro-apoptotic effects inhibiting the phosphorylation of Akt and S6 ribosomal protein and inducing the down-regulation of cyclin D1. MTA inhibits melanoma cell proliferation and in vivo tumor growth particularly in BRAF mutant melanoma cells. These data reveal a naturally occurring drug potentially useful for melanoma treatment

  17. A comparative histologic study on furcal perforation repair with Root MTA and Pro Root MTA in fully developed teeth in dog

    Directory of Open Access Journals (Sweden)

    Rahimi S.

    2005-07-01

    Full Text Available Background and Aim: The goal of endodontics is to seal the root canal system from the orifice to apical constriction completely and tridimensionally.Hence perforations during root canal therapy, because of caries or resorptions must be sealed and obturated with ideal materials. The aim of this study was to histologically compare two kinds of mineral trioxide aggregate Root MTA and Pro Root MTA for furcal perforation repair in developed teeth in dog. Materials and Methods: In this experimental study, thirty teeth consisting of second, third and fourth mandibular premolars of five German shepherd dogs were selected. Twenty-four teeth were randomly divided into four experimental groups (6 teeth each. One pair of Root MTA and Pro Root MTA groups studied in one month and the other in three months intervals. Positive and negative control groups was each contained three teeth. In positive control group, perforations were not treated and negative control group contained intact teeth. In experimental groups perforations repaired after one week exposure to oral cavity with Root MTA or Pro Root MTA. After time intervals animals were subjected to vital perfusion and 6 m histologic sections were prepared. Inflammation and hard tissue formation were ranked by Cox criteria. Data were analysed using Mann-Whitney and Chi-Square statistical tests with P0.05. Conclusion: Mineral Trioxide Aggregate is an adequate material for furcal perforation repair in dog’s teeth. Root MTA could be a good substitute for Pro Root MTA considering the lower cost and similar characteristics.

    There were several materials used to seal different types of perforation defects. MTA is one of these restorative materials that is considered the most effective, biocompatible, non-toxic, and non-irritant; promote bone healing and cementum regeneration. The objective of this article was to review and summarize the sealing ability of MTA compared with the other materials used for sealing different types of root perforations of permanent teeth. A literature search was conducted using Medline, accessed via the National Library of Medicine Pub Med from 2005 to 2015 searching for articles related to sealing ability of MTA. This study found that factors affecting prognosis are the size, site of the perforation and time elapsed as well as the repair material. MTA is an important filling material to be used for sealing different types of perforations when perforated sites sealed immediately with MTA. PMID:27347231

    Addressed some factual inaccuracies and presented alternative positions on key issues raised in the article by Greene and Ablon (this issue) on the question, "What does the Multimodal Treatment Study (MTA) tell us about effective psychosocial treatment for attention deficit hyperactivity disorder (ADHD)?" The Greene and Ablon critique does not present for the reader's consideration the full range of findings from the MTA study, notably those most relevant to psychosocial treatment, and articulates a theoretical position that effective treatment requires matching treatment to children's assessed needs, an approach not taken in the MTA study. In this article, I present the full range of findings from the MTA study related to psychosocial treatment effects, correct the misperceptions that exist about the study based on limited reviews such as Greene and Ablon's, and review the empirical and experimental design issues that produced the decision by the MTA investigative team to study the effects of intensive, comprehensive psychosocial treatment. I argue that the questions asked by the MTA study about psychosocial treatment were important, relevant, and were addressed well in the MTA study design. PMID:11294072

The DOEE method divides operator or rater assessment into two parts: 1 Detection Error (DE -- rater agreement in detecting the same regions to mark, and 2 Outline Error (OE -- agreement of the raters in outlining of the same lesion. Methods DE, OE and Similarity Index (SI values were calculated for two raters tested on a set of 17 fluid-attenuated inversion-recovery (FLAIR images of patients with MS. DE, OE, and SI values were tested for dependence with mean total area (MTA of the raters' Region of Interests (ROIs. Results When correlated with MTA, neither DE (ρ = .056, p=.83 nor the ratio of OE to MTA (ρ = .23, p=.37, referred to as Outline Error Rate (OER, exhibited significant correlation. In contrast, SI is found to be strongly correlated with MTA (ρ = .75, p  Conclusions The DE and OER indices are proposed as a better method than SI for comparing rater agreement of ROIs, which also provide specific information for raters to improve their agreement.

    Full Text Available Introduction: MTA is composed of various metal oxides, calcium oxide and bismuth. It has good biological properties and is indicated in cases of endodontic complications. Several commercial formulations are available and further studies are necessary to evaluate these materials. Objective: To evaluate pH and calcium releasing of MTA Fillapex® compared with gray and white MTA. Material and methods: Gray and white MTA (Angelus and MTA Fillapex® (Angelus were manipulated and placed into polyethylene tubes and immersed in distilled water. The pH of these solutions was measured at 24 hours, 7 days and 14 days. Simultaneously, at these same aforementioned periods, these materials’ calcium releasing was quantified, through atomic absorption spectrophotometry. The results were submitted to ANOVA, with level of significance at 5%. Results: Concerning to pH, the materials present similar behaviors among each other at 24 hours (p > 0.05. At 7 and 14 days, MTA Fillapex® provided significantly lower pH values than the other materials (p < 0.05. Regarding to calcium releasing, at 24 hours and 7 days, MTA Fillapex® provided lower releasing than the other materials (p < 0.05. After 14 days, differences were found between MTA Fillapex® and gray MTA (p < 0.05. Conclusion: All materials showed alkaline pH and calcium releasing, with significantly lower values for MTA Fillapex® sealer.

    Full Text Available Abstract Background Streptococcus agalactiae (group B Streptococcus; GBS is a significant bacterial pathogen of neonates and an emerging pathogen of adults. Though transcriptional regulators are abundantly encoded on the GBS genome, their role in GBS pathogenesis is poorly understood. The mtaR gene encodes a putative LysR-type transcriptional regulator that is critical for the full virulence of GBS. Previous studies have shown that an mtaR- mutant transports methionine at reduced rates and grows poorly in normal human plasma not supplemented with methionine. The decreased virulence of the mtaR mutant was correlated with a methionine transport defect; however, no MtaR-regulated genes were identified. Results Microarray analysis of wild-type GBS and an mtaR mutant revealed differential expression of 12 genes, including 1 upregulated and 11 downregulated genes in the mtaR mutant. Among the downregulated genes, we identified a cluster of cotranscribed genes encoding a putative methionine transporter (metQ1NP and peptidase (pdsM. The expression of four genes potentially involved in arginine transport (artPQ and arginine biosynthesis (argGH was downregulated and these genes localized to two transcriptional units. The virulence factor cspA, which encodes an extracellular protease, was downregulated. Additionally, the SAN_1255 locus, which putatively encodes a protein displaying similarity to plasminogen activators, was downregulated. Conclusion To our knowledge, this is the first study to describe the global influence of MtaR on GBS gene expression. This study implicates the metQ1NP genes as encoding the MtaR-regulated methionine transporter, which may provide a mechanistic explanation for the methionine-dependent growth defect of the mtaR mutant. In addition to modulating the expression of genes involved in metabolism and amino acid transport, inactivation of mtaR affected the expression of other GBS genes implicated in pathogenesis.

    2005-06-01

    Full Text Available This study evaluated the biocompatibility of mineral trioxide aggregate (MTA after direct capping of exposed pulp tissue in dog's teeth. Class I cavities were prepared in 26 teeth from 3 adult dogs. MTA was applied over the exposed pulp in 13 teeth and paste of calcium hydroxide plus distilled water (control was applied in the remaining 13 teeth. After 90 days, the animals were killed; the maxilla and mandible were dissected and sectioned to obtain individual roots. The samples were processed histologically. The pulp and periapical response observed with the use of MTA was similar to that of calcium hydroxide paste. In all specimens, there was a dentin bridge obliterating the exposure, an intact odontoblastic layer, no inflammatory cells, normal connective pulp tissue, normal apical and periapical regions and no bone tissue changes. Similar to calcium hydroxide, MTA presented excellent response when used for direct pulp capping.O objetivo deste trabalho foi avaliar a biocompatibilidade do agregado de trióxido mineral (MTA, após proteção pulpar direta em dentes de cães. Foram preparadas cavidades de Classe I, em 26 dentes de 3 cães adultos. O MTA foi aplicado sobre 13 dentes e a pasta de hidróxido de cálcio (grupo controle foi aplicada sobre os 13 dentes remanescentes. Após 90 dias, os animais foram mortos, a maxila e a mandíbula foram dissecadas e os dentes foram seccionados para obtenção de raízes individualizadas. Os espécimes foram processados histologicamente. A resposta do tecido pulpar e periapical foi semelhante para o MTA e o hidróxido de cálcio. Em todos os espécimes havia ponte de dentina obliterando o local da exposição pulpar, camada odontoblástica íntegra, ausência de células inflamatórias, tecido pulpar normal, e ausência de alterações na região periapical e óssea. Da mesma maneira que o hidróxido de cálcio, o MTA apresentou excelente biocompatibilidade quando usado para proteção pulpar direta.

  11. Confidentiality and American semen donors.

    Science.gov (United States)

    Karow, A M

    1993-01-01

    Most American donor insemination programs include a policy of complete confidentiality concerning the donor of the semen. This is the result of a long legal tradition of American constitutional law. However, some slight abridgement of this body of legal decisions might be very much in the best interests of children arising from donor insemination, and even--in most cases, in fact--the donors themselves. With regard to the children, the factors involved are both those of genetic counseling, should the need arise, and psychological development. Of course, as at present, the donor must be relieved of all responsibility, both legal and financial. PMID:8348162

  12. The MTA family proteins as novel histone H3 binding proteins

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available Abstract Background The nucleosome remodeling and histone deacetylase complex (Mi2/NRD/NuRD/NURD has a broad role in regulation of transcription, DNA repair and cell cycle. Previous studies have revealed a specific interaction between NURD and histone H3N-terminal tail in vitro that is not observed for another HDAC1/2-containing complex, Sin3A. However, the subunit(s responsible for specific binding of H3 by NURD has not been defined. Results In this study, we show among several class I HDAC-containing corepressor complexes only NURD exhibits a substantial H3 tail-binding activity in vitro. We present the evidence that the MTA family proteins within the NURD complex interact directly with H3 tail. Extensive in vitro binding assays mapped the H3 tail-binding domain to the C-terminal region of MTA1 and MTA2. Significantly, although the MTA1 and MTA2 mutant proteins with deletion of the C-terminal H3 tail binding domain were assembled into the endogenous NURD complex when expressed in mammalian cells, the resulting NURD complexes were deficient in binding H3 tail in vitro, indicating that the MTA family proteins are required for the observed specific binding of H3 tail peptide by NURD in vitro. However, chromatin fractionation experiments show that the NURD complexes with impaired MTA1/2-H3 tail binding activity remained to be associated with chromatin in cells. Conclusions Together our study reveals a novel histone H3-binding activity for the MTA family proteins and provides evidence that the MTA family proteins mediate the in vitro specific binding of H3 tail peptide by NURD complex. However, multiple mechanisms are likely to contribute to the chromatin association of NURD complex in cells. Our finding also raises the possibility that the MTA family proteins may exert their diverse biological functions at least in part through their direct interaction with H3 tail.

    Full Text Available The aim of this in vitro study is to compare the microleakage of a root perforation sealed with MTA (mineral trioxide aggregate (group M to that sealed with MTA following Er:YAG laser irradiation (group ML. Forty-two recently extracted human monoroot teeth were used. Two cavities were prepared on each root surface. Randomly, on each root, the exposed dentine of one cavity was irradiated prior to MTA filling using an Er:YAG laser with the following settings: 200 mJ/pulses under an air water spray, 10 Hz, pulse duration of 50 μsec, and 0.7 mm beam diameter. All cavities were then sealed with MTA. submitted to thermocycling and immersed in 2% methylene blue dye solution for 12 h. The penetration of methylene blue in the microleakage of cavity was observed and recorded. The mean value dye penetration in cavities sealed with MTA following Er:YAG laser irradiation (23.91±14.63% was lower than that of unlased cavities sealed only with MTA (25.17±17.53%. No significant difference was noted. The use of an Er:YAG laser beam for dentinal conditioning prior to MTA filling of perforated roots did not decrease significantly the microleakage of MTA sealing when compared to the conventional use of MTA filling.

    2013-01-01

    Full Text Available Purpose: Few studies have comparatively evaluated the push-out bond strength of different calcium silicate-based materials (CSMs used in furcal perforation repair. The objective of this in vitro study was to comparatively evaluate the push-out bond strength of commercially available CSMs used as furcation repair materials, in the presence of blood contamination. Materials and Methods: Furcal perforations were made in 120 molars and were divided on the basis of the repair material used (ProRoot MTA, Biodentine, and MTA Plus, blood contamination, and duration of setting time (24 h vs. 7 days. Push-out bond strength was measured and analyzed by three-way analysis of variance (ANOVA test. Results: Push-out bond strength increased with time. The 24-h push-out strength of MTA was less than that of Biodentine. Blood contamination affected the push-out bond strength of MTA Plus irrespective of the setting time. Conclusion: Caution should be taken while condensing restorative materials over furcation repair materials.

The aim of this study was to examine whether the MTA1 gene is associated with the process of proliferation and invasion by regulating several molecular targets in gastric cancer. MTA1 expression in 61 gastric cancer tissue and adjacent noncancerous tissues was analyzed by immunohistochemistry. The prognostic value of MTA1 for overall survival and disease-free survival was determined by Kaplan–Meier estimates, and the significance of differences between curves was evaluated by the log-rank test. Furthermore, overexpression of MTA1 in SGC7901 and BGC823 cells promoted cell cycle progression, cell adhesion, and cell invasion. Our study found that MTA1 is overexpressed in gastric cancers, which contributes to malignant cell growth by facilitating cell cycle progression through upregulation of cyclin D1 and accelerates the migration and invasion of human gastric cancer cells by regulating expression of fibronectin and MMP2/MMP9. Taken together, MTA1 was involved in the pathogenesis of gastric cancer and might be a candidate therapeutic target in gastric cancer. Keywords: cell cycle, cell adhesion, migration

    Background The apexification is the first alternative treatment on a permanent tooth when, after a tooth trauma and in the presence of immature apex trauma, pulp necrosis occurs. Many studies have demonstrated the efficacy of mineral trioxide aggregate (MTA) as apical sealing material of choice in these cases, but has a degree of filtration as all other materials. The objective of this study was to analyze the seal ability of MTA on the duct walls in immature teeth unirradicular apexes, using indirect vibration. Material and Methods The study was conducted on 45 teeth divided into 3 groups: Group A or control group in which no vibration for placing the MTA was used, Group B and C or groups where indirect vibration analysis was used. All samples were immersed in methylene blue to assess filtration. After performing longitudinal cuts millimetric measuring were made of the degree of filtration, divided into 3 degrees (2mm each grade filtration). Results Results obtained confirm our hypothesis, obtaining lesser degree of filtration those groups in which indirect vibration (Groups B and C) was performed. It was shown that the degree of filtration is closely linked to the degree of adaptation. Conclusions MTA vibration offers better results in its adaptation to the canal walls, significantly reducing the degree of filtration. Key words:Apexification, MTA, filtration, indirect vibration.

    Full Text Available Abstract The present study aimed at evaluating the cytotoxic effects of a novel cement called CER on periodontal fibroblast-like cells of mice (MDPL-20, in comparison with different formulations of Mineral Trioxide Aggregate (MTA, by means of the cell viability test (MTT and cell morphology analysis. Thirty-two round-shaped samples were fabricated with the following cements: white MTA, white and gray CER and experimental white MTA. The samples were immersed in serum-free culture medium for 24 hours or 7 days (n = 16. The extracts (culture medium + components released from the cements were applied for 24 hours to previously cultured cells (40.000 cells/cm2 in the wells of 24-well plates. Cells seeded in complete culture medium were used as a negative control. Cell viability was assessed using the MTT assay. Two samples of each cement were used for cell morphology analysis by Scanning Electron Microscopy (SEM. The extracts obtained at the 7-day period presented higher cytotoxicity compared with the 24-hour period (p 0.05. However, at the 7-day period, the experimental white MTA presented no significant difference in comparison with the other cements (p > 0.05. At the 7-day period, CER cement presented cytotoxic effects on fibroblast-like cells, similar to different MTA formulations. However, the immersion period in the culture medium influenced the cytotoxicity of the cements, which was greater for CER cement at 24 hours.

    Mushroom tyrosinase-associated lectin-like protein (MtaL) binds to mature Agaricus bisporus tyrosinase in vivo, but the exact physiological function of MtaL is unknown. In this study, the crystal structure of recombinant MtaL is reported at 1.35 Å resolution. Comparison of its structure with that of the truncated and cleaved MtaL present in the complex with tyrosinase directly isolated from mushroom shows that the general β-trefoil fold is conserved. However, differences are detected in the loop regions, particularly in the β2-β3 loop, which is intact and not cleaved in the recombinant MtaL. Furthermore, the N-terminal tail is rotated inwards, covering the tyrosinase-binding interface. Thus, MtaL must undergo conformational changes in order to bind mature mushroom tyrosinase. Very interestingly, the β-trefoil fold has been identified to be essential for carbohydrate interaction in other lectin-like proteins. Comparison of the structures of MtaL and a ricin-B-like lectin with a bound disaccharide shows that MtaL may have a similar carbohydrate-binding site that might be involved in glycoreceptor activity.

    $^{\\rm {180m}}$Ta is the rarest naturally occurring quasi-stable isotope and the longest lived metastable state which is known. Its possible decay via the $\\beta^-$ or the electron capture channel has never been observed. This article presents a search for the decay of $^{\\rm {180m}}$Ta with an ultra low background Sandwich HPGe gamma spectrometry setup in the HADES underground laboratory. No signal is observed and improved lower partial half-life limits are set with a Bayesian analysis to $5.8\\cdot10^{16}$ yr for the $\\beta^-$ channel and $2.0\\cdot10^{17}$ yr for the electron capture channel (90% credibility). The total half-life of $^{\\rm {180m}}$Ta is longer than $4.5\\cdot10^{16}$ yr. This is more than a factor of two improvement compared to previous searches.

    Objective To evaluate solubility and sealing ability of Mineral Trioxide Aggregate (MTA) and root-end filling materials. Material and Methods The materials evaluated were: MTA, Calcium Silicate Cement with zirconium oxide (CSC/ZrO2), and zinc oxide/eugenol (ZOE). Solubility test was performed according to ANSI/ADA. The difference between initial and final mass of the materials was analyzed after immersion in distilled water for 7 and 30 days. Retrograde cavities in human teeth with single straight root canal were performed by using ultrasonic tip CVD 9.5107-8. The cavities were filled with the evaluated materials to evaluate sealing ability using the bacterial leakage test with Enterococcus faecalis. Bacterial leakage was evaluated every 24 hours for six weeks observing the turbidity of Brain Heart infusion (BHI) medium in contact with root apex. Data were submitted to ANOVA followed by Tukey tests (solubility), and Kruskal-Wallis and Dunn tests (sealing ability) at a 5% significance level. Results For the 7-day period, ZOE presented highest solubility when compared with the other groups (p<0.05). For the 30-day period, no difference was observed among the materials. Lower bacterial leakage was observed for MTA and CSC/ZrO2, and both presented better results than ZOE (p<0.05). Conclusion MTA and CSC/ZrO2 presented better bacterial sealing capacity, which may be related to lower initial solubility observed for these materials in relation to ZOE. PMID:27119759

  12. Initial Emittance Measurements of the Fermilab Linac Beam Using the MTA Beamline

    CERN Document Server

    Johnstone, C

    2012-01-01

    The MTA beam line has been specifically designed to facilitate measurements of the Fermilab Linac beam emittance and properties utilizing a long, 10m, element-free straight. Linac beam is extracted downstream of the 400-MeV electrostatic chopper located in the Booster injection line. This chopper cannot be utilized for MTA beam, and therefore the entire Linac beam pulse is directed into the MTA beamline. Pulse length manipulation is provided by the 750-keV electrostatic chopper at the upstream end of the Linac and, using this device, beam can be delivered from 8 {\\mu}sec up to the full 50 {\\mu}sec Linac pulse length. The 10 m emittance measurement straight exploits and begins at the 12' shield wall that separates the MTA Experimental Hall and beamline stub from the Linac enclosure. A quadrupole triplet has been installed upstream of the shield wall in order to focus a large, 1.5-2" (~95% width) beam through the shield wall and onto a profile monitor located at the exit of the shielding. Another profile monito...

    Full Text Available The aim of this study was to determine, by Atomic Absorption Spectrometry (AAS, the concentration levels of 11 metals in Type V gray and structural white PC, ProRoot MTA, and MTA Bio. Samples, containing one gram of each tested cement, were prepared and transferred to a 100 mL Teflon tube with a mixture of 7.0 mL of nitric acid and 21 mL of hydrochloric acid. After the reaction, the mixture was filtered and then volumed to 50 mL of distilled water. For each metal, specific patterns were determined from universal standards. Arsenic quantification was performed by hydride generator. The analysis was performed five times and the data were statistically analyzed at 5% level of significance. Only the cadmium presented concentration levels of values lower than the quantification limit of the device. The AAS analysis showed increased levels of calcium, nickel, and zinc in structural white PC. Type V PC presented the greatest concentration levels of arsenic, chromium, copper, iron, lead, and manganese (P<0.05. Bismuth was found in all cements, and the lowest concentration levels were observed in Portland cements, while the highest were observed in ProRoot MTA. Both PC and MTA-based cements showed evidence of metals inclusion.

    Introduction: There are various studies looking at the effects of formocresol (FC) and mineral trioxide aggregate (MTA) on pulpotomy of primary molars. This is a systematic review of literature comparing the success rates of MTA and FC in pulpotomy of primary molars. Materials and Methods: The study list was obtained using PubMed, EMBASE, Scopus, Science Citation Index, Iran Medex, Google Scholar, the Cochrane Library, and also some hand searches contains through dental journals approved by the Iranian Ministry of Health. Papers which met the inclusion were accepted. The quality of studies for the meta-analysis was assessed by a series of validity criteria according to Jadad's scale. Eight qualified studies met the criteria. Terms of clinical outcomes and radiographic findings were evaluated in all studies to assess clinical success and root resorption. Fixed model was applied to aggregate the data of homogenous studies. A random effect model was carried out for measuring the effect size of heterogeneous studies. Results: The overall clinical and radiographic success rates based on the data suggested that MTA was superior to FC (P=0.004) with the Odds Ratio=3.535 and 95% confidence interval (1.494-8.369). Conclusion: Primary molars pulpotomy with MTA have better clinical and radiographic success rates than FC. (Iranian Endodontic Journal 2008;3:45-9) PMID:24146670

    This study was designed to investigate the resistance to dislodgment provided by MTA HP, a new high-plasticity calcium silicate-based cement. Biodentine and White MTA Angelus were used as reference materials for comparison. Three discs 1 ± 0.1 mm thick were obtained from the middle third of the roots of 5 maxillary canines. Three 0.8-mm-wide holes were drilled on the axial surface of each root disc. Standardized irrigation was performed. Then the holes were dried with paper points and filled with one of the three tested cements. The filled dental slices were immersed in a phosphate-buffered saline (PBS) solution (pH 7.2) for 7 days before the push-out assessment. The Kruskal-Wallis test was applied to assess the effect of each endodontic cement on the push-out bond strength. Mann-Whitney with Bonferroni correction was used to isolate the differences. The alpha-type error was set at 0.05. All specimens had measurable push-out values and no premature failure occurred. There were significant differences among the materials (p <0.05). The Biodentine specimens had the highest push-out bond strength values (p < 0.05). MTA HP had significantly higher bond strength than White MTA (p < 0.05). MTA HP showed better push-out bond strength than its predecessor, White MTA; however, Biodentine had higher dislodgment resistance than both MTA formulations. PMID:27305515

    Today, in the high-tech, fast-paced health care arena in which professionals practice, confidential information and the right to privacy in one's personal life have become very basic concerns of society. Among the general public, a genuine interest exists about potential invasions of privacy and the undermining of confidentiality. Members of society are more educated concerning rights as the result of multimedia and education presented by health care professionals. New challenges for the professional attending to the health needs of society will be encountered as the complexity of health care increases (Pohlman, 1988). One must remember that the most intensely private and personal moments of an individual's life are revealed in hospital settings. Health care professionals have a duty at all times to diligently protect the confidence of each patient unless specific criteria is met so that disclosure is warranted. Dilemmas encountered often are complex and require a certain degree of expertise for resolution to occur. If ethical theory and principles are used in combination with some of the specific guidelines apropos to resolving confidentiality issues, creative solutions can be devised. Professionals, by the very nature of their experience and education, possess the talent to achieve this goal. Consequently, when guidelines for confidential treatment of information are followed, public trust of professionals will be ensured. Once trust is established, a significant step will have been taken toward the solution of problems of confidentiality in modern day health care. PMID:9393042

    The Long Term Evolution of UMTS is one of the latest steps in an advancing series of mobile telecommunications systems. Many articles have already been published on the LTE subject but these publications have viewed the subject from particular perspectives. In the present paper, a different approach has been taken. We are interested in the security features and the cryptographic algorithms used to ensure confidentiality and integrity of the transmitted data. A closer look is taken to the two EPS confidentiality and integrity algorithms based on the block cipher algorithm AES: the confidentiality algorithm EEA2 and the integrity algorithm EIA2. Furthermore, we focused on the implementation of both algorithms in C language in respect to the specifications requirements. We have tested our implementations according to the testsets given by the 3rd Generation Partnership Project (3GPP) implementation document. Some examples of the implementation tests are presented bellow.

    Aim. To report the management and orthograde technique of MTA placement in case of reverse architecture maxillary premolars. Summary. Two cases of 17-year-old and 21-year-old female patients were referred to endodontic speciality for management of maxillary premolar having reverse architecture with wide immature open apex like a bell mouth. In both the cases, after control of intraradicular infection, it was decided to use MTA for apexification and obturation of canals. Orthograde placement of MTA is a challenging procedure in terms of length control and condensation especially in divergent irregular reverse architecture wide open apex. A novel technique with the help of finger plugger, sterilized paper point, and ultrasonic agitation for 3D compaction of MTA at apical reverse architecture was used. Thickening of the canal wall and complete apical closure were confirmed one year after the treatment. PMID:27313910

    Full Text Available Background: Achieving a good apical seal for root canals is known to be associated with good mineral trioxide aggregate (MTA adaptation to dentin. Aims: This study aims to compare the marginal adaptation of MTA with root dentin between orthograde and retrograde application techniques using microcomputed tomography (micro-CT analysis. Settings and Design: Fifty-two single-rooted human teeth were divided into four equal groups: (Group 1 Retrograde MTA (RMTA, (Group 2 Orthograde MTA (OMTA, (Group 3 Etched RMTA (ERMTA, and (Group 4 Etched OMTA (EOMTA. Materials and Methods: For Group 1, 3-mm retrograde cavities were prepared and filled with MTA. For Group 2, the apical 6 mm of the canals were filled with MTA and sealed with sealer cement and warm gutta-percha. In Groups 3 and 4, canals were treated the same as Groups 1 and 2, respectively, except that before placing the MTA, canals were irrigated with 17% ethylenediaminetetraacetic acid (EDTA. After 48 hours, all the teeth were analyzed using a micro-CT scanner. Statistical Analysis: Mean dentin-MTA contact and the mean length and width of each gap was analysed using one-way analysis of variance (ANOVA. Statistical significance was set at an α level of 5%. Results: No significant difference in gap volumes was observed in the dentin-MTA adaptation in both orthograde and retrograde application techniques. However, significant difference in the gap volumes was observed between RMTA and ERMTA (P = 0.045. Etching significantly improved the MTA-Dentin adaptation (P < 0.05. The type of application technique did not significantly improve the dentin-MTA adaptation, instead with the use of 17% EDTA, a significant improvement could be achieved. Conclusion: Within the limitations of the present study, it concludes that MTA adaptation to dentin tooth structure is not significantly different between an orthograde and retrograde approach. However, the use of EDTA significantly improved the MTA-Dentin adaptation.

  9. Methanol:coenzyme M methyltransferase from Methanosarcina barkeri -- substitution of the corrinoid harbouring subunit MtaC by free cob(I)alamin.

    Sauer, K; Thauer, R K

    1999-05-01

    Methyl-coenzyme M formation from coenzyme M and methanol in Methanosarcina barkeri is catalysed by an enzyme system composed of three polypeptides MtaA, MtaB and MtaC, the latter of which harbours a corrinoid prosthetic group. We report here that MtaC can be substituted by free cob(I)alamin which is methylated with methanol in an MtaB-catalysed reaction and demethylated with coenzyme M in an MtaA-catalysed reaction. Methyl transfer from methanol to coenzyme M was found to proceed at a relatively high specific activity at micromolar concentrations of cob(I)alamin. This finding was surprising because the methylation of cob(I)alamin catalysed by MtaB alone and the demethylation of methylcob(III)alamin catalysed by MtaA alone exhibit apparent Km for cob(I)alamin and methylcob(III)alamin of above 1 mm. A possible explanation is that MtaA positively affects the MtaB catalytic efficiency and vice versa by decreasing the apparent Km for their corrinoid substrates. Activation of MtaA by MtaB was methanol-dependent. In the assay for methanol:coenzyme M methyltransferase activity cob(I)alamin could be substituted by cob(I)inamide which is devoid of the nucleotide loop. Substitution was, however, only possible when the assays were supplemented with imidazole: approximately 1 mm imidazole being required for half-maximal activity. Methylation of cob(I)inamide with methanol was found to be dependent on imidazole but not on the demethylation of methylcob(III)inamide with coenzyme M. The demethylation reaction was even inhibited by imidazole. The structure and catalytic mechanism of the MtaABC complex are compared with the cobalamin-dependent methionine synthase. PMID:10215883

    Root perforations are accidental events that may occur during the treatment, causing tissue inflammation and alveolar bone loss of integrity of the periodontium. In such cases, the radiological evidence is fundamental in the formulation of the diagnosis, in the choice of therapy (surgical or non-surgical) and finally for the assessment of prognosis of the dental element. In non-surgical treatment of endodontic lesions, the material used for the repair of the defect root should have biocompatibility, antibacterial activity, ability to induce healing of periodontal tissues and radiopacity. The Mineral Trioxide Aggregate (MTA) is a silicate-based cement introduced in dental clinical practice with good radiopacity, biocompatibility and bone induction. This article describes the use of MTA in endodontic repair of a perforation of the middle third root and the success of non-surgical treatment was dimonstrated radiographicaly. PMID:24042428

    Full Text Available Some manufacturers have recently added specific components to improve the ease of handling and insertion material properties of MTA in order to create MTA-based sealers. Objective The aim of this study was to evaluate the healing of periapical lesions in canine teeth after a single session of endodontic treatment with MTA Fillapex® compared with Sealapex® or Endo-CPM-Sealer®. Material and Methods Sixty-two root canals were performed on two 1-year-old male dogs. After coronal access and pulp extirpation, the canals were exposed to the oral cavity for 6 months in order to induce periapical lesions. The root canals were prepared, irrigated with a solution of 2.5% sodium hypochlorite and filled with gutta-percha and different sealers, according to the following groups: 1 Sealapex®; 2 Endo-CPM-Sealer®; and 3 MTA Fillapex®. Some teeth with periapical lesions were left untreated for use as positive controls. Healthy teeth were used as negative controls. After 6 months, the animals were sacrificed and serial sections from the roots were prepared for histomorphologic analysis and stained with hematoxylin and eosin and the Brown and Brenn technique. The lesions were scored according to pre-established histomorphologic parameters and the scores statistically analyzed using the Kruskal-Wallis test. Results All 3 materials produced similar patterns of healing (p>0.05; in particular, persistent inflammation and absence of complete periapical tissue healing were consistently noted. Conclusions Preparation of the infected root canals followed by filling with the materials studied was insufficient to provide complete healing of the periapical tissues.

    Full Text Available Introduction: Endodontic treatment of young permanent teeth with incomplete root formation and necrotic pulp has been a challenge for the dentist. It is necessary to induce the formation of apical barrier (apical plug, enabling the complete root canal filling. Objective: This retrospective clinical study compared the protocols for treatment of teeth with incomplete root formation, using calcium hydroxide (CH or mineral trioxide aggregate (MTA. Material and methods: 28 patients with incomplete root formation have undergone root canal treatments in the period from 2000 to 2009 were selected. The procedures for cleaning, shaping and intracanal medication (CH paste were performed in a standardized manner. In 13 patients, after using the CH paste (14 days, apical plugs with MTA were made. In the remaining 15 teeth monthly exchanges with CH paste were executed until it was observed radiographically the formation of the apical barrier. In all cases the canals were filled conventionally with gutta-percha and sealer. Initially, follow-ups were made on a quarterly and semiannually at the end of first year. Results: All apical lesions showed apical healing between 4 and 13 months after starting treatment. There was not noted the continuing process of root formation. Conclusion: It was concluded that the treatment of teeth with incomplete root formation and necrotic pulp with the use of MTA as apical plug has the same clinical results compared with the use of CH, with the advantage of less clinical time.

    Background: An ideal root canal obturation requires a complete dentinal wall adaptation of sealer and Gutta-percha combinations without any gap formations. Aims: The aim of the study was to evaluate the dentinal wall adaptation ability of MTA Fillapex root canal sealer using stereo electron microscope (SEM). Methods: Twenty-four, single-rooted, human maxillary incisor teeth were used. All canals were prepared with a rotary nickel–titanium (Ni–Ti) instrument to a size F3 file. Teeth divided into two equal groups and one of the experimental groups was filled with AH Plus, and the other group was filled with MTA Fillapex using Gutta-percha single cone as a core material. The roots were prepared for SEM evaluation, and serial scanning electron photomicrographs were taken at ×50, ×100, ×500, and ×1000 magnifications. The gaps between the root canal sealer and canal walls were detected and measured in coronal, middle, and apical thirds. For each section, the highest value among the detected gap formations was recorded. Statistical Analysis: Mann–Whitney U-test, Freidman, and Wilcoxon tests were used. Results: The statistical analysis showed no significant difference between two sealers in terms of gap formation (P > 0.05). Conclusions: MTA Fillapex has a similar dentinal wall adaptation ability as AH Plus does. PMID:27217633

    Full Text Available The purpose of this study was to evaluate the hydrogenionic potential and electrical conductivity of Portland cements and MTA, as well as the amount of arsenic and calcium released from these materials. In Teflon molds, samples of each material were agitated and added to plastic flasks containing distilled water for 3, 24, 72 and 168 h. The results were analyzed with a Kruskal-Wallis non-parametric test for global comparisons and a Dunn-Tukey test for pairwise comparisons. The results revealed no significant differences in the pH of the materials (p > 0.05. The electrical conductivity of the cements were not statistically different (p > 0.05. White non-structural cement and MTA BIO released the largest amount of calcium ions into solution (p 0.05. The results indicated that the physico-chemical properties of Portland cements and MTA were similar. Furthermore, all materials produced an alkaline environment and can be considered safe for clinical use because arsenic was not released. The electrical conductivity and the amount of calcium ions released into solution increased over time.

    Metastasis-associated protein 1 (MTA1) high expression has been detected in a wide variety of human aggressive tumors and plays important roles in the malignant biological behaviors such as invasion,metastasis,and angiogenesis.However,the specific roles and mechanisms of MTA1 protein in regulating the malignant behaviors of non-small-cell lung cancer (NSCLC) cells still remain unclear.To elucidate the detailed functions of MTA1 protein,we down-regulated the MTA1 protein expression in NSCLC cell line by RNA interference (RNAi) in vitro,and found that down-regulation of MTA1 protein significantly inhibited the migration and invasion potentials of 95D cells.Further research revealed that down-reguiation of MTA1 protein significantly decreased the activity of matrix metalloproteinase-9,which could be the mechanism responsible for the inhibition of 95D cells migration and invasion.In addition,the tube formation assay demonstrated that the number of complete tubes induced by the conditioned medium of MTA1-siRNA 95D cells was significantly smaller than that of 95D cells.These findings demonstrate that MTA1 protein plays important roles in regulating the migration,invasion,and angiogenesis potentials of 95D cells,suggesting that MTA1 protein down-regulation by RNAi might be a novel therapeutic approach to inhibit the progression of NSCLC.

Cell proliferation, osteo/odontoblastic gene expression and mineralization induced by MTA mixed with PG were evaluated. MTA discs (5 mm in diameter, 2 mm thick were prepared and soaked in culture medium for 7 days. Next, the discs were removed and the medium used to culture dental pulp stem cells (DPSC for 28 days. Cells survival was evaluated using MTS assay (24, 72 and 120 h and differentiation with RT-PCR (ALP, OCN, Runx2, DSPP and MEPE and alizarin red staining (7 and 14 days. Data were analysed using one-way ANOVA and Tukey’s post-hoc analysis (a=0.05.Results The addition of PG significantly increased setting time, flowability and Ca2+ release, but it compromised the hardness of the material. SEM showed that 50/50 group resulted porous material after setting due to the incomplete setting reaction, as shown by XRD analysis. The addition of PG (80/20 and 50/50 was not capable to improve cell proliferation or to enhance gene expression, and mineralized deposition of DPSC after 7 and 14 days as compared to the 100/0.Conclusion Except for flowability, the addition of PG did not promote further improvements on the chemical and physical properties evaluated, and it was not capable of enhancing the bioactivity of the MTA.

    Full Text Available This study evaluated the sealing ability of apical plugs made of white and gray MTA-Angelus® and white Portland cement placed via the root canal and having different thicknesses (2, 5 and 7 mm. Ninety extracted human single-rooted teeth were instrumented using a size 40 K-file to standardize the foraminal opening by the stepback technique. The teeth were assigned to 3 groups (n=30, according to the material used for fabrication of the apical plugs: A = gray MTA; B = white MTA; C = white Portland cement. The groups were subdivided into groups of 10 teeth each according to the apical plug thickness (2, 5 and 7 mm. Marginal apical dye leakage was assessed using 0.2% Rhodamine B solution in which the specimens were immersed for 72 hours at 37ºC. The roots were sectioned longitudinally in a buccolingual direction for apical plug exposure, and digital photographs were taken and analyzed by Image Tool image-analysis software. Data were analyzed statistically by Kruskal-Wallis and Dunn's tests. Significance level was set at 5%. The least percent leakage was observed for 5- and 7-mm-thick plugs (p0.05 was found between gray MTA and white Portland cement. Among the three materials analyzed, white MTA presented the highest marginal leakage (p<0.05. The findings of the present study showed that gray MTA and Portland cement had better sealing ability than white MTA when used as apical plugs. Dye leakage was smaller for 5- and 7-mm-thick plugs compared to 2-mm-thick plugs.

    The enzyme system catalyzing the formation of methyl-coenzyme M from methanol and coenzyme M in Methanosarcina barkeri is composed of the three different polypeptides MtaA, MtaB and MtaC of which MtaC harbors a corrinoid prosthetic group. The heterologous expression of mtaA and mtaB in Escherichia coli has been described previously. We report here on the overproduction of the apoprotein of MtaC in E. coli, on its reconstitution to the active holoprotein with either cob(II)alamin or methyl-cob(III)alamin, and on the properties of the reconstituted corrinoid protein. Reconstituted MtaC was found to contain 1 mol bound cobamide/mol. EPR spectroscopic evidence is presented for a His residue as an axial ligand to Co2+ of the bound corrinoid. This active-site His was identified by site-directed mutagenesis as His136 in the MtaC sequence that contains four His residues. The reconstituted MtaC, in the cob(I)amide oxidation state, was methylated with methanol in the presence of MtaB and demethylated with coenzyme M in the presence of MtaA. In the presence of both MtaB and MtaA, methyl-coenzyme M was formed from methanol and coenzyme M at specific rates comparable to those determined for the enzyme system purified from M. barkeri. M. barkeri contains an isoenzyme of MtaA designated MtbA. The isoenzyme reacted with MtaC with only 2.5% of the activity of MtaA. PMID:9654068

    Mobile ad hoc networks (MANETs) are self-configuring infrastructure-less networks comprised of mobile nodes that communicate over wireless links without any central control on a peer-to-peer basis. These individual nodes act as routers to forward both their own data and also their neighbours' data by sending and receiving packets to and from other nodes in the network. The relatively easy configuration and the quick deployment make ad hoc networks suitable the emergency situations (such as human or natural disasters) and for military units in enemy territory. Securing data dissemination between these nodes in such networks, however, is a very challenging task. Exposing such information to anyone else other than the intended nodes could cause a privacy and confidentiality breach, particularly in military scenarios. In this paper we present a novel framework to enhance the privacy and data confidentiality in mobile ad hoc networks by attaching the originator policies to the messages as they are sent between nod...

  18. Security Analysis of Generalized Confidential Modulation

    Directory of Open Access Journals (Sweden)

    2013-05-01

    Full Text Available We propose a new evaluation method for ‘generalized confidential modulation (GCM’ for quantum communication. Confidential modulation real izes a secret communication by using secret information for modulation and noise in a ch annel. Y-00 is one of the famous methods of GCM for quantum communication. The existing evaluat ion methods for GCM are based on stream ciphers. They can estimate its analytical se curity and the evaluation depends on the security status of pseudo random number generator ( PRNG which controls the modulation. On the other hand, our method is based on mode of oper ation for block ciphers and clears the weaknesses from structural viewpoint. Using our met hod, we can compare the security of different GCM structures. Our method of security ev aluation and comparison does not depend on the security status of PRNG. From the results of our evaluation, we conclude that the security of GCM is limited to computational securit y.

    The effectiveness of the confidential unit exclusion (CUE) procedure recommended by the Food and Drug Administration has been questioned by the blood banking community. The purpose of this study was to determine whether donors were informing the blood center correctly regarding the disposition (transfuse or do not transfuse) of their donated blood. A letter explaining the confidential study and requesting permission to send the participant a questionnaire noting his or her self-exclusion choice was mailed to 230 donors who had chosen transfuse and 276 donors who had chosen do not transfuse. After consent was obtained, participants were sent a second packet and asked to indicate whether they had chosen correctly and, if not, to identify reasons for that incorrect choice. A seven-word terminology quiz made up of words from the CUE form was also enclosed. All participants who had chosen transfuse indicated that this was the correct choice. Approximately 50 percent of those who had chosen do not transfuse indicated that this was an incorrect choice; the most common reason was that "I was not paying attention." The most frequently misunderstood term was "confidential." Donors who chose do not transfuse had a significantly higher rate of error on the terminology quiz (p less than 0.01) than did those who chose transfuse. PMID:2219257

    We study how to enable arbitrary randomized algorithms in Byzantine fault-tolerant (BFT) settings. We formalize a randomized BFT protocol and provide a simple and efficient construction that can be built on any existing BFT protocols while adding practically no overhead. We go one step further to revisit a confidential BFT protocol (Yin et al., SOSP '03). We show that their scheme is potentially susceptible to safety and confidentiality attacks. We then present a new protocol that is secure in the stronger model we formalize, by extending the idea of a randomized BFT protocol. Our protocol uses only efficient symmetric cryptography, while Yin et al.'s uses costly threshold signatures. We implemented and evaluated our protocols on microbenchmarks and real-world use cases. We show that our randomized BFT protocol is as efficient as conventional BFT protocols, and our confidential BFT protocol is two to three orders of magnitude faster than Yin et al.'s, which is less secure than ours.

  3. Improved Message Authentication and Confidentiality Checking

    International Nuclear Information System (INIS)

    The most confusing areas of the secured network communications are the message authentication and confidentiality checking. The attacks and the counter measures have become so convoluted that the users in this area begin to account for all contingencies. Two session-key generation techniques are used here to generate two separate session keys K1 and K2; and both the sender and the reveiver share these keys for higher degree of authentication and confidentiality. For this, the message is first encrypted by the key K1, and then the intermediary message authenticatin code (MAC) is generated by encrypting the encrypted message using the key K2. Then, the encrypted message and the intermediary MAC is again encrypted by using the K2 and concatenated with the encrypted message and sent to the destination. At the receiving end, first, the received ciphertext is encrypted by using key K2 and compared to the received MAC. The received ciphertext again is decrypted by the key K2 and compared with the first decrypted MAC twice by the key K2. The plaintext is obtained by decrypting the received ciphertext first by K2 and then by K1, using the corresponding decryption techniques respectively. The encryption techniques with key K2 provides the authentication and with key K1 provides the confidentiality checking of the transmitted message. The developed technique can be applied to both academic and commercial applications in online or offline electronic transactions for security.(authors)

    Aim: To evaluate the shear bond strength of MTA with three different types of adhesive systems- self-adhering flowable composite, etch and rinse adhesive system and self etch adhesive system. Methodology: MTA specimens (n = 60) were prepared using cylindrical acrylic blocks, having a central cavity with 4 mm diameter and 2 mm depth. MTA was mixed and placed in the prepared cavity, and was covered with a moist cotton pellet and temporary filling material. The specimens were divided into 3 groups which were further divided into 2 sub-groups (45 Minutes and 24 hours). After the application of bonding agents composite resin was placed over the MTA surface. The specimens were tested for shear bond strength and readings were statically analyzed. Result: After 24 hrs the mean value of etch and rinse group was significantly higher than self etch and the self adhering composite groups. Among the 45 minutes groups there were no significant difference. Conclusion: In single visit after 45 minutes self adhering flowable can be used successfully as a final restorative material in place of conventional flowable composite without using any alternative adhesive system over MTA.

    CRAC is an IT-architecture-based method for assessing and comparing confidentiality risks of distributed IT systems. The method determines confidentiality risks by taking into account the effects of the leakage of confidential information (e.g. industrial secrets), and the paths that may be followed by different attackers (e.g. insider and outsider). We evaluate its effectiveness by applying it to a real-world outsourcing case.

    Context: Mineral trioxide aggregate (MTA) is a biocompatible repair material that is often used along with glass ionomer cement (GIC) in many clinical situations. Aims: In this study, the interface of GIC and MTA was examined, and the effect of time on this interface was tested. Materials and Methods: Forty 9-mm hollow cylindrical glass molds were filled with MTA and then according to the group either conventional GIC or resin-modified GIC (RMGIC) is filled immediately or after 45 min. The specimens were then sectioned, carbon coated, and examined using a scanning electron microscope (SEM) and the elemental analysis was done. Statistical Analysis: Observational study, no statistical analysis done. Results: The SEM showed that both the groups underwent adhesive separation and gap formation at the interface. The specimens in which GIC was condensed over freshly mixed MTA (group IIA and group IIB) also showed cohesive separation in MTA; however, it was more in the GIC condensed after 45 min over MTA groups (group IA and group IB). The results were better for conventional GIC than RMGIC. Conclusions: GIC can be applied over freshly mixed MTA with minimal effects on the MTA, but this effect decreases with time. PMID:27217640

    We studied peaks of calcium hydroxyapatite - CHA on defects grafted with MTA, treated or not with Light Emitting Diode - LED or IR Laser. 54 rats were divided in 6 groups each subdivided into 3 subgroups (15,21,30d). LED (λ850 +/- 10nm) or IR Laser (λ850 nm) was applied over (LED) or in 4 points around the defect at 48 h intervals for 15 days. Raman readings were taken at the surface of the defect. The smaller overall intensity of the peak was found in Group MTA + Laser (1510.2 +/- 274.1) and the highest on Group LED (2322 +/- 715). There were no statistically significant differences between non-irradiated subjects on regards the CHA peaks. On the other hand, there were statistically significant differences between the Group Clot and LED, Clot and Laser, and Clot and MTA + Laser (p =0.01, p = 0.02, p = 0.003). There were no significant differences between Group MTA and MTA + LED (p=0.2) but significant differences were seen between Groups MTA and MTA + Laser (p=0.01). Significant differences were also observed between Groups LED and Laser (p MTA + LED and MTA + Laser (p=0.009). MTA, due to its characteristics, seemed to be directly affected by the light. However, the use of either phototherapy positively affected bone healing similarly as observed on different studies using other biomaterials. The overall analysis of our results indicated that the use of either light source resulted in a better, more advanced, and of quality bone repair.

  18. Fast neutron induced depopulation of the 180mTa isomer

    International Nuclear Information System (INIS)

    The fast neutron induced depopulation of the 180mTa (I, Kπ 9,9-) isomer to the 1+ ground state has been detected by activation. The natural Ta foils together with the 232Th monitoring target were activated using the neutron flux produced by the 7.3 MeV electron beam at a special choice of the converters and shields. The Kα2 X-ray line (54.6 keV) of Hf has been successfully observed in the γ-ray spectrum of activated Ta. It is attributed to the activity of 180gTa (T1/2 = 8.15 h). The yields of three reactions: 232Th(n, f), 181Ta(n, γ)182Ta, and 180mTa(n, n')180gTa, have been measured at the same conditions and compared. Finally, the mean probability of the 180mTa depopulation after the MeV-neutron scattering is deduced to be as high as ∼ 0,4. Almost complete K-mixing above the neutron binding energy is established

    Directory of Open Access Journals (Sweden)

    Sharvani G S

    2012-10-01

    Full Text Available Designing an effective load balancing algorithm is difficult due to Dynamic topology of MANET. Toaddress the problem, a load balancing routing algorithm namely Modified Termite Algorithm (MTA hasbeen developed based on ant’s food foraging behavior. Stability of the link is determined based on nodestability factor ‘’. The stability factor “ “of the node is the ratio defined between the “hello sent” and“hello replied” by a node to its neighbors. This also indicates the link stability in relation to other pathstowards the destination. A higher ratio of “” indicates that the neighbor node is more stable. Using thisconcept pheromone evaporation for the stable node is fine tuned such that if the ratio “” is more, theevaporation is slow and if “” is less the evaporation is faster. This leads to decreasing of the pheromonecontent in an optimal path which may result in congestion. These paths can be avoided using efficientevaporation technique. The MTA developed by adopting efficient pheromone evaporation technique willaddress the load balancing problems and expected to enhance the performance of the network in terms ofthroughput, and reduces End-to-end delay and Routing overheads

    Social, technical and legal conditions of the current practice of medicine make it necessary to insist on certain actions and circumstances that may jeopardize the confidentiality of information, offered by patients to their health providers. Therefore, some effects of the current Chilean law are analyzed in this respect, regarding access to data from the clinical record of a patient. Also, the risks of putting certain data on social networking sites are analyzed, as well as some of its effects on clinical practice. The reasons because of mandatory reporting of diseases, meaning danger to public health, is allowed, are mentioned. We also discuss the difficulties involved in managing the results of preventative health screenings and its knowledge by third parties, as well as some possible violations of personal privacy, regarding dissemination of some people health information and its further mention or figuration in mass media. We conclude that it is a must for both physicians and other health team members, to safeguard confidentiality of data to which they have had access, as well as the need to know the relevant law, in order to respect human dignity of patients, each one as a person. We address the attention to the possibility that, practicing in a different way, it could endanger the reliability of clinical records, also impairing the quality of people's health care.

    For the Open Days, CERN will be transparent for all visitors. It's also the occasion to remember that the Ombuds' door is fully open every day of the year for all persons working for or on behalf of CERN.   The door is open, but as soon as it's closed for a discussion, the office becomes a place where total confidentiality is preserved. This may appear as a contradiction, no? The Ombuds is available to help everyone in all circumstances, but his clause of confidentiality prevents him from acting without the consent of his “visitors”. How can he possibly resolve the in-house conflicts in groups, or units, if all the parties do not voluntarily participate in its resolution? The answer is clear: the job of the Ombuds is to help the parties resolve their conflict by themselves. He will provide a few rules of communication, a process of mutual respect, suggest some possibilities that the parties may want to follow, and mediate the dispute so that people...

  13. Genetic secrets: Protecting privacy and confidentiality in the genetic era

    Energy Technology Data Exchange (ETDEWEB)

    Rothstein, M.A. [ed.

    1998-07-01

    Few developments are likely to affect human beings more profoundly in the long run than the discoveries resulting from advances in modern genetics. Although the developments in genetic technology promise to provide many additional benefits, their application to genetic screening poses ethical, social, and legal questions, many of which are rooted in issues of privacy and confidentiality. The ethical, practical, and legal ramifications of these and related questions are explored in depth. The broad range of topics includes: the privacy and confidentiality of genetic information; the challenges to privacy and confidentiality that may be projected to result from the emerging genetic technologies; the role of informed consent in protecting the confidentiality of genetic information in the clinical setting; the potential uses of genetic information by third parties; the implications of changes in the health care delivery system for privacy and confidentiality; relevant national and international developments in public policies, professional standards, and laws; recommendations; and the identification of research needs.

    This study evaluated the bond strength of mineral trioxide aggregate (MTA) to root canal dentin after the performance of various irrigation procedures to remove triple antibiotic paste (TAP). A total of 56 single-rooted human mandibular premolars were instrumented using a rotary system to size 40 and divided randomly into a control group (no intracanal dressing) and three experimental groups (TAP application for 28 days). TAP was then removed by rinsing with 10 mL 2.5% NaOCl using three irrigation systems (Vibringe sonic irrigation, CanalBrush, and syringe irrigation). The coronal and middle parts of root canals were then obturated with MTA. After storage for 1 week, each specimen was embedded in an acrylic block and sectioned horizontally (2-mm-thick slices) at two levels (coronal and middle). Bond strength of MTA to root canal dentin was assessed in 28 samples per group via push-out test using a universal testing machine. Data from the four groups were compared using one-way analysis of variance. Tukey's test was used for multiple comparisons. Push-out bond strength values were significantly higher in the control and Vibringe groups than in the CanalBrush and syringe irrigation groups (p irrigation system may increase the push-out bond strength of MTA compared with the use of the CanalBrush or syringe irrigation.

    Objective: To evaluate the antibacterial and antifungal properties of calcium-based cement, Biodentine (Ca3SiO2), compared to commercial glass ionomer cements (GICs) and mineral trioxide aggregate (MTA). Materials and Methods: Pellets of GICs, ProRoot MTA, and Biodentine were prepared to test the influence of these cements on the growth of four oral microbial strains: Streptococcus mutans, Enterococcus faecalis, Escherichia coli, and Candida albicans; using agar diffusion method. Wells were formed by removing the agar and the manipulated materials were immediately placed in the wells. The pellets were lodged in seeded plates and the growth inhibition diameter around the material was measured after 24-72 h incubation at 37°C. The data were analyzed using analysis of variance (ANOVA) test to compare the differences among the three cements at different concentrations. Results: Test indicates that the antimicrobial activity of Biodentine, on all the microorganisms tested, was very strong, showing a mean inhibition zone of 3.2 mm, which extends over time towards all the strains. For Biodentine, GIC, and MTA, the diameters of the inhibition zones for S. mutans were significantly larger than for E. faecalis, Candida, and E. coli (P Biodentine created larger inhibition zones than MTA and GIC.

    The electrical activity of a network of mammalian neurons is mapped with a Multi-Transistor Array (MTA) fabricated with extended CMOS technology. The spatial resolution is 7.4 μm on an area of 1 mm2 at a sampling frequency of 6 kHz for a complete readout of 16,384 sensor transistors. Action potentials give rise to extracellular voltages with amplitudes in a range of 500 μV. On the basis of the high resolution in space and time, correlation algorithms are used to identify single action potentials with amplitudes as low as about 200μV, and to assign the signals to the activity of individual neurons even in a dense network.

    This study evaluated the sealing ability of apical plugs fabricated with gray MTA Angelus sealer, CPM TM sealer and MBPc sealer. The root canals of 98 extracted single-rooted human teeth were instrumented with #5 to #1 Gates Glidden drills according to the crown-down technique until the #1 drill could pass through the apical foramen. The specimens were then prepared with K-files, starting with an ISO 50 until an ISO 90 could be visualized 1 mm beyond the apex. After root canal preparation, the external surface of each root was rendered impermeable and roots were assigned to 3 experimental groups (n = 30), which received a 5-mm thick apical plug of gray MTA Angelus, CPM and MBPc, and two control groups (n=4). The remaining portion of the canal in the experimental groups was filled by the lateral condensation technique. The teeth of each group, properly identified, were fixed on utility wax by their crowns and were placed in plastic flasks, leaving the apex free and facing upward. The flasks were filled with 0.2% Rhodamine B solution, pH 7.0, so as to completely cover the root apex of all teeth. The sealing ability was analyzed by measuring 0.2% Rhodamine B leakage after all groups had been maintained in this solution for 48 hours. Data were analyzed statistically by Kruskal-Wallis test and Dunn test with a=5%. The results showed that, among the tested materials used for fabrication of apical plugs, MBPc sealer had the least amount of leakage with statistically significant difference (p<0.05).

    Full Text Available Apical sealing is essential for the success of paraendodontic surgery, so any procedure that may favor an adequate sealing of the apical remainder should be performed. The purpose of this study was to evaluate the influence of diode laser irradiation on the apical sealing of root-end cavities with MTA retrofillings. Root canals in twenty extracted human teeth were shaped with K-files and filled with gutta-percha. The apexes were cut off and root-end preparations were performed. The roots were divided randomly in 2 groups. Group 1 (ten specimens was retrofilled with MTA. Group 2 was irradiated with diode laser, with 1 W for 20 seconds, on the apical surface and root end cavity before retrofilling with MTA. The specimens had their external surfaces impermeabilized with cyanoacrylate, except for the apical surface, and were then immersed in 1% rhodamine B dye for 72 h and placed in plaster stone. After that, the specimens were submitted to longitudinal abrasion until half of the root remained. The linear dye leakage was observed in these mid-roots between the root canal wall and retrofilling. The linear dye leakage was measured with Image Lab software, and the results were statistically analyzed with Student's t test. There were no statistically significant differences between the two groups (p > 0.05. The diode laser irradiation did not improve the apical sealing of MTA retrofillings under the conditions of this in vitro study.O selamento apical é fundamental para o sucesso da cirurgia parendodôntica.

The specimens were then sectioned, carbon coated, and examined using a scanning electron microscope (SEM and the elemental analysis was done. Statistical Analysis: Observational study, no statistical analysis done. Results: The SEM showed that both the groups underwent adhesive separation and gap formation at the interface. The specimens in which GIC was condensed over freshly mixed MTA (group IIA and group IIB also showed cohesive separation in MTA; however, it was more in the GIC condensed after 45 min over MTA groups (group IA and group IB. The results were better for conventional GIC than RMGIC. Conclusions: GIC can be applied over freshly mixed MTA with minimal effects on the MTA, but this effect decreases with time.

  15. WTO confidential: the case of asbestos.

    Castleman, Barry

    2003-01-01

    The World Trade Organization (WTO), established in 1995, adjudicates "trade disputes" between member nations in cases with human rights, cultural, environmental, and public health significance. Throughout the resolution process and even after a case's conclusion, little of what happens is made accessible to the public. However, it is one thing to criticize the WTO for its lack of transparency from outside the process and another to critically examine what was withheld from disclosure and what dangers that presents. This is the inside story from a scientific adviser to one party in a WTO case, who analyzes what happened from a public health point of view. The analysis concludes that the public health justification for banning asbestos was accepted in the end by WTO economists, despite the WTO's bias in favor of the party (Canada) making the free trade challenge (to public health legislation), despite the WTO's lack of expertise in science, medicine, engineering, and public health, and despite important erroneous statements made to the WTO under the cover of confidentiality. The case nevertheless illustrates that the WTO's threat to national sovereignty could never withstand the light of day if the limitations and dangers of the process were open for all to see.

    2013-01-01

    Introduction Endodontic surgery is a valuable option for maintaining patient's natural dentition when previous orthograde endodontic treatments fail to succeed. Proper root-end preparation and placement of a retro-filling material are recommended for successful endodontic surgery. The objective of this experimental study was to compare sealing ability of Resilon/Epiphany system, as a potential root-end filling material, with ProRoot MTA using both dye and bacterial leakage models. Materials and Methods Ninety two single-rooted extracted human teeth were decoronated and prepared endodontically. Specimens were randomly divided into four experimental groups (n = 20) and four control groups (n = 3). After removal of apical 3 mm and root-end cavity preparation, MTA, or Resilon were used to fill root end cavities. For bacterial leakage, specimens (20 for each experimental group, 3 negative, and 3 positive controls) were subjected to E. faecalis over a 70-day period. Methylene blue was used for dye leakage (the same in number as before). Using stereomicroscope (40× mag.) complete dye leakage was assessed after 72 h. Kaplan-Meier survival analysis was performed for bacterial leakage. The data was analyzed using t-test and Chi-square analysis (α = 0.05). Results All of the positive controls and none of negative controls revealed leakage. Result of log rank test showed no significant difference between MTA and Resilon in time of bacterial leakage at the end of the 70 days (P > 0.05) There was also no statistical difference in complete dye leakage for both groups (P > 0.05). Conclusion Leakage occurred in both MTA and Resilon as root-end filling material but the difference was not statistically significant. Resilon might be noticed as a potential root-end filling material if good isolation is attainable. PMID:24171025

    Introduction Endodontic surgery is a valuable option for maintaining patient's natural dentition when previous orthograde endodontic treatments fail to succeed. Proper root-end preparation and placement of a retro-filling material are recommended for successful endodontic surgery. The objective of this experimental study was to compare sealing ability of Resilon/Epiphany system, as a potential root-end filling material, with ProRoot MTA using both dye and bacterial leakage models.

  19. MTA-enriched nanocomposite TiO2-polymeric powder coatings support human mesenchymal cell attachment and growth

    International Nuclear Information System (INIS)

    The objective of the study described in this paper was the development of novel polymer/ceramic nanocomposite coatings for implants through the application of ultrafine powder coating technology. Polyester resins were combined with µm-sized TiO2 (25%) as the biocompatibility agent, nTiO2 (0.5%) as the flow additive and mineral trioxide aggregates (ProRoot® MTA, 5%) as bioactive ceramics. Ultrafine powders were prepared and applied to titanium to create continuous polymeric powder coatings (PPCs) through the application of electrostatic ultrafine powder coating technology. Energy dispersive x-ray analysis confirmed that MTA had been incorporated into the PPCs, and elemental mapping showed that it had formed small clusters that were evenly distributed across the surface. Scanning electron microscopy (SEM) revealed continuous and smooth, but highly textured surface coatings that contrasted with the scalloped appearance of commercially pure titanium (cpTi) controls. Atomic force microscopy revealed intricate nano-topographies with an abundance of submicron-sized pits and nano-projections, evenly dispersed across their surfaces. Inverted fluorescence microscopy, SEM and cell counts showed that human embryonic palatal mesenchymal cells attached and spread out onto PPC and MTA-enriched PPCs within 24 h. Mitochondrial enzyme activity measured viable and metabolically active cells on all of the surfaces. After 72 h of growth, cell counts and metabolic activity were significantly higher (P < 0.05) on the grey-MTA enriched PPC surfaces, than on unmodified PPC and cpTi. The novel polymer/ceramic nanocomposites that were created with ultrafine powder coating technology were continuous, homogenous and nano-rough coatings that enhanced human mesenchymal cell attachment and growth.

    Full Text Available Background: Endodontic obturating materials should form monoblocks, reinforcing the treated teeth against fracture. Aim: To evaluate and compare the effect of two resin sealers and a MTA sealer on the fracture resistance of endodontically treated teeth. Materials and Methods: Fifty single-rooted mandibular premolars, decoronated at cemento-enamel junction, were divided into 5 groups (n = 10 each. Group 1 and group 2 served as negative and positive controls. Cleaning and shaping of root canals was done using ProTaper rotary files and 3% sodium hypochlorite irrigation. Obturation was done using AH plus (Dentsply, Germany (group 3, MetaSEAL (Parkell, USA (group 4, MTA Fillapex (Angeles, Brazil (group 5 sealers and gutta-percha. Teeth were subjected to vertical loading using a universal testing machine and the point at which fracture of the roots occurred was recorded. The data was subjected to statistical analysis using one way analysis of variance (ANOVA followed by pair-wise comparison using Tukey′s Post-hoc test. Results: AH Plus showed better fracture resistance among the sealer groups. Statistically, no significant difference was found between MetaSEAL and Fillapex groups. Conclusion: MTA Fillapex as a root canal sealer was not able to reinforce the tooth against fracture.

    Full Text Available The aim of this study was the comparative evaluation of inflammatory reactions and tissue responses to four growth factors, or mineral trioxide aggregate (MTA, or a zinc-oxide-eugenol-based cement (IRM as controls, when used for the repair of furcal perforations in dogs’ teeth. Results showed significantly higher inflammatory cell response in the transforming growth factorβ1 (TGFβ1 and zinc-oxide-eugenol-based cement (IRM groups and higher rates of epithelial proliferation in the TGFβ1, basic fibroblast growth factor (bFGF, and insulin growth factor-I (IGF-I groups compared to the MTA. Significantly higher rates of bone formation were found in the control groups compared to the osteogenic protein-1 (OP-1. Significantly higher rates of cementum formation were observed in the IGF-I and bFGF groups compared to the IRM. None of the biologically active molecules can be suggested for repairing furcal perforations, despite the fact that growth factors exerted a clear stimulatory effect on cementum formation and inhibited collagen capsule formation. MTA exhibited better results than the growth factors.

    The synthesis of the designer drug 4-methylthioamphetamine (4-MTA) has been carried out using the well-known Leuckart reaction in four versions. The treatment of 4-methylthiophenylacetone with formamide, mixture of formamide/formic acid, ammonium formate, and mixture of ammonium formate and formic acid followed by acid hydrolysis brought about the formation of 4-MTA contaminated with a number of impurities. The gas chromatography mass-spectrometry (GC-MS) analysis of the reaction mixtures allowed identification of the most prominent impurities, such as diasteromers of N,N-di-[β-(4-methylthiophenyl)isopropyl]amine, N,N-di-[β-(4-methylthiophenyl)isopropyl]methylamine, N,N-di-[β-(4-methylthiophenyl)isopropyl]formamide, the Schiff bases derived from 4-MTA and 4-methylbenzaldehyde (benzaldimine) and 4-methylthiophenylacetone (ketimine) as well as some heterocycles: 4-methyl-5-(4'-methylthiophenyl)pyrimidine, 4-(4'-methylthiobenzyl)pyrimidine, 2,6-dimethyl-3,5-di-(4'-methylthiophenyl)pyridine, 2,4-dimethyl-3,5-di-(4'-methylthiophenyl)pyridine. The correctness of identification was confirmed by independent synthesis of these compounds. Each synthesized reference compound was characterized by means of MS, (1)H and (13)C NMR, and IR methods. The stereochemistry of (RR/SS) diasteromer of N,N-di-[β-(4-methylthiophenyl)isopropyl]amine was confirmed by a crystallographic method. PMID:21982394

  3. Evaluation in a competitive utility environment: the threat of confidentiality

    International Nuclear Information System (INIS)

    Utilities have become concerned that their competitors will desire access to energy-related data--including energy-efficiency data collected by utilities from their energy- efficiency programs--that they may regard as proprietary or confidential. In the future, disputes about confidentiality may focus more on costs and market information (as well as energy use and load data) than on energy-efficiency data per se. So far, the discussion has been limited to ratepayer-funded data. Consequently, many utilities are now requesting that the data (including evaluation data) they submit to their utility regulatory commissions remain confidential. Withholding utility information from the public is likely to harm the evaluation community that depends on the free flow of information for improving the practice of evaluation as well as for disseminating the lessons learned from particular program evaluations. Confidentiality will also have significant policy implications. In response to these concerns, in late 1995 and early 1996, we conducted a survey of state public utility commissions (PUCs) in the U.S. to assess: (1) the relative importance of the issue of confidential data in the regulatory arena; (2) the regulatory response to utility requests for confidentiality (e.g., formal policies, guidelines, rules and procedures, and decisions); and (3) the type of data filed as confidential with PUCS. We focus on the first two objectives of this study. In addition to our interviews, we reviewed selected state statutes, judicial and PUC decisions, rules and procedures, protective orders, and interim policy documents. Evaluators need to understand the context of confidentiality as well as the response of the regulatory commissions to confidentiality, because evaluators will need to adapt to a new environment where energy-related data and information may be harder to obtain and distribute. We propose that regulators conduct the following activities as soon as possible: 1. Assess

    Full Text Available Cloud Computing creates a dynamicresource sharing platform that provides dataanalytically to the proficient users who are atdemand to access data present in the cloud. Asthis data is stored outside the data owner's boundaries, they are skeptical for utilizingcloud technology in order to store or accesstheir data from those external cloudproviders who are outside their own controlenvironment. There are many issues for theseactive clients (companies or individuals to bepetrified at the thought of using cloudcomputing paradigm. Some of the main issuesthat make the clients swear against Cloud Computing are generated from threeimportant security aspects: Confidentiality, Integrity, and Availability.In this Research, we focused only on securitymodels that relate Confidentiality issues. We performed a literature Review foranalyzing the existing confidentialityframeworks and security models. We thendesigned a new theoretical framework forconfidentiality in Cloud computing byextracting this literature. We expect this Framework when implemented practically inthe cloud computing paradigm, may generatehuge successful results that motivate the clients to transform their businesses on to Cloud.

    Full Text Available Statement of problem: Endodontic treatment of necrotic teeth with open apices is a challenge. After ruling out surgery as a treatment scheme and introduction of the multivisit apexification which in turn had its disadvantages, apical plug seems to be a suitable substitute treatment plan for such cases. Apical plug makes the treatment through formation of a barrier against the obturating material in a single visit.Purpose: The purpose of this study was to compare histologically the periapical healing using MTA and calcium hydroxide apical plugs after intervals of 4 and 12 weeks in cats.Materials and Methods: In this clinical trial study 64 canines of 16 healthy and mature cats were divided into 3 groups after a periapical lesion formation by over instrumentation in the apical area with files up to no.120. The first group included 24 teeth on which MTA apical plug was applied. The second group included 24 teeth on which Ca (OH 2 apical plug was applied. In both groups the canals were filled with gutta percha and sealer. The third group included 16 control teeth whose canals were left empty after instrumentation and debridement. The access cavities of all teeth were sealed with varnish and amalgam and the vital perfusion of cats was performed in 4 and 12 week intervals. Statistical analysis was established by χ2 and independence test.Results: After 4 weeks, periapical healing in the first group was 90%, in the second group 80% and in the third group, it was only 12.5 %. After 12 weeks, periapical healing occurred in 100% of the MTA group, while it was 57.1% in the second and 40%in the third group .Generally, in the study of histological parameters of healing, no statistical significant difference was observed between the 2 experimental groups,although the MTA group results were much better than the Ca (OH 2 group especially at 12 weeks.Conclusion: The use of MTA apical plug is more effective than Ca (OH 2 in treatment of necrotic teeth with open

  6. Nuclear exports. Parliamentary control and confidentiality

    International Nuclear Information System (INIS)

    With its decision taken on 21. October 2014 (Az.: 2 BvE 5/11) the Federal Constitutional Court (BVerfG) decided during court proceedings between administrative bodies on the scope and limits of the parliamentary right of information. Even though the proceeding did not deal with nuclear exports but arm exports, foreign trade law, however, does not only designate an export licence obligation for military weapons but also for so called dual-use goods meaning goods, which can be used both for friendly as well as for military purposes. The export of these goods requires according to the so-called Dual-Use Regulation (EG) 428/2009 a licence. Annex I category 0 of the regulation (EG) 428/2009 lists a variety of nuclear materials, plants and equipment items for which this licence applies. In the same manner as arm exports, also exports of nuclear dual-use goods are being discussed in a special cabinet committee, the Federal Security Council (BSR), which shall coordinate cross-departmentally the German security and defence policy under consideration of economic interests and which categorises its results, according to the rules of procedure, as confidential. Also legally not regulated but common ''preliminary enquiries'' at the responsible Federal Ministry or rather Federal Office of Economics and Export Control by companies which plan an export and want to affirm the general approval for their export business prior to conclusion of contract take not only place for arm exports but also for nuclear dual-use goods. The decision by the Federal Constitutional Court can be applied to consultations about the authorisation of nuclear dual-use goods.

    In the present density functional studies, structural, mechanical and magneto-electronic properties of CaTaO{sub 3,} SrTaO{sub 3} and BaTaO{sub 3} perovskites have been investigated. The calculated structural parameters by DFT and analytical methods are found consistent with the experiments. The analytically calculated tolerance factors of these compounds as well as their mechanical properties show that they are stable in the cubic phase. Furthermore elastic properties show that these materials are ductile in nature and confirm that BaTaO{sub 3} is harder than the rest compounds. The calculated spin dependent magneto-electronic properties reveal the paramagnetic metallic nature of these compounds. The electrical conductivity curve demonstrates significant conductivity above room temperature. On the basis of the presented properties it is expected that these compounds could be efficient electrode materials and need experimental investigations. - Highlights: • MTaO{sub 3} (M = Ca, Sr and Ba) perovskites are investigated theoretically in the frame work of density functional theory. • Mechanical properties explain the stability of these compounds and show that BaTaO{sub 3} is more ductile. • The magneto-electronic studies reveal the paramagnetic metallic nature of these compounds. • Significant electrical conductivity is observed above room temperature.

    The success of parallel computing in solving real-life computationally-intensive problems relies on their efficient mapping and execution on large-scale multiprocessor architectures. Many important applications are both unstructured and dynamic in nature, making their efficient parallel implementation a daunting task. This paper presents the parallelization of a dynamic unstructured mesh adaptation algorithm using three popular programming paradigms on three leading supercomputers. We examine an MPI message-passing implementation on the Cray T3E and the SGI Origin2OOO, a shared-memory implementation using cache coherent nonuniform memory access (CC-NUMA) of the Origin2OOO, and a multi-threaded version on the newly-released Tera Multi-threaded Architecture (MTA). We compare several critical factors of this parallel code development, including runtime, scalability, programmability, and memory overhead. Our overall results demonstrate that multi-threaded systems offer tremendous potential for quickly and efficiently solving some of the most challenging real-life problems on parallel computers.

    Diabetes mellitus is a chronic disease which affects the healing ability of the pulp and periodontium. The aim of the present study was to assess the histopathologic response of dental pulp to pulp capping using MTA or CEM cement in diabetic rats. Thirty two Wistar male rats aged between 8 and 10 weeks (weight: 200-250g) were divided into two groups of diabetic (n=16) and healthy (n=16) animals and then subdivided into MTA and CEM subgroups. In each group, 10 MTA treated, 10 CEM treated and 12 intact (without any intervention) teeth were analyzed. Intact teeth were considered as a baseline inflammation control. Then, class I cavity was made in the maxillary first molars teeth with pinpoint pulpal exposure. Either MTA or CEM cement was then placed over exposed pulp as pulp capping agent and the cavities were restored using resin- modified glass ionomer cement. Both teeth of rats in subgroups remained intact without any intervention. After four weeks, the rats were sacrificed and the teeth were subjected to histological evaluation in terms of inflammation intensity, dentin bridge formation and dentin bridge continuity. The CEM cement treated diabetic rats exhibited a significant higher inflammatory response when compared to healthy control group (P=0.004) whereas, MTA treated diabetic rats did not exhibit a significant higher inflammatory response in comparison to healthy controls. There was no significant difference between MTA and CEM cement in the induction of dentin bridge formation in diabetic and healthy controls. This preliminary study suggests that MTA is a superior dental material than CEM cement for pulp therapy in subjects with diabetes. PMID:25635253

    2011-01-01

    We study the multi-receiver wiretap channel with public and confidential messages. In this channel, there is a transmitter that wishes to communicate with two legitimate users in the presence of an external eavesdropper. The transmitter sends a pair of public and confidential messages to each legitimate user. While there are no secrecy constraints on the public messages, confidential messages need to be transmitted in perfect secrecy. We study the discrete memoryless multi-receiver wiretap channel as well as its Gaussian multi-input multi-output (MIMO) instance. First, we consider the degraded discrete memoryless channel, and obtain an inner bound for the capacity region by using an achievable scheme that uses superposition coding and binning. Next, we obtain an outer bound, and show that this outer bound partially matches the inner bound, providing a partial characterization for the capacity region of the degraded channel model. Second, we obtain an inner bound for the general, not necessarily degraded, disc...

    Because of cutbacks and downsizing within the petroleum industry, it has become one of the largest users of contract personnel to provide services that were previously provided by senior levels of management. This paper explored the application of common law fiduciary duties and the duty of confidence to the independent workforce. It examined to what extent fiduciary duties apply to independent consultants and the best way for the employer to protect itself from the potentialmisuse of confidential information. Part 1 of the paper described fiduciary duties. A fiduciary relationship was described as one that possesses the following three characteristics: (1) the fiduciary has scope for the exercise of some discretion of power, (2) the fiduciary can unilaterally exercise that power to affect the beneficiary's practical interests, and (3) the beneficiary is peculiarly vulnerable to the fiduciary holding the discretion of power. Three examples of how the courts treated some arguments regarding fiduciaries were presented. Part 2 of this paper discussed how trade secrets and confidential information should be handled. It was explained, that regardless of fiduciary duties, the unauthorized use of confidential information by an independent contractor can give rise to liability and an award of damages by the courts. Some examples where the Supreme Court of Canada found breach of confidence by a party were presented. Information communicated from an employer to an employee can be divided into the following three categories: (1) publicly accessible and not confidential, (2) confidential and must be treated as such while an employee is employed, but if learned becomes part of the employees skill and knowledge, and (3) specific confidential trade secrets that cannot lawfully be used for anyone's benefit but the employer's. Issues regarding defining rights and obligations by contract were also discussed.

  8. Shareholders' agreements in Denmark

    2010-01-01

    The article warns that with effect from 1 March 2010, the new Danish Companies Act (on public and private limited companies) has seriously weakened the effect of shareholders’ agreements which have been entered into on Danish companies. These agreements (in the act’s new terminology: “owners......’ agreements”) cannot bind the company within the sense of company law under the new state of law, and voting rights agreements, agreements on right of pre-emption etc. will therefore only apply at the level of contract law between the parties to the agreement. This article for European Business Law Review...... analyses the consequences of this. Rights and duties in the owners’ agreements must now be reiterated to the greatest possible extent in the company’s articles of association so that the precepts become binding on the company and its management.

  14. Confidential data in a competitive utility environment: A regulatory perspective

    Energy Technology Data Exchange (ETDEWEB)

    Vine, E.

    1996-08-01

    Historically, the electric utility industry has been regarded as one of the most open industries in the United States in sharing information but their reputation is being challenged by competitive energy providers, the general public, regulators, and other stakeholders. As the prospect of competition among electricity power providers has increased in recent years, many utilities have been requesting that the data they submit to their utility regulatory commissions remain confidential. Withholding utility information from the public is likely to have serious and significant policy implications with respect to: (1) consumer education, the pursuit of truth, mutual respect among parties, and social cooperation; (2) the creation of a fair market for competitive energy services; (3) the regulatory balance; (4) regional and national assessments of energy-savings opportunities; (5) research and development; and (6) evaluations of utility programs, plans, and policies. In a telephone survey of all public utility commissions (PUCs) that regulate electric and gas utilities in the U.S., we found that almost all PUCs have received requests from utility companies for data to be filed as confidential, and confidential data filings appear to have increased (both in scope and in frequency) in those states where utility restructuring is being actively discussed. The most common types of data submitted as confidential by utilities dealt with specific customer data, market data, avoided costs, and utility costs.

  9. Misinterpretations in agreement and agreement attraction.

    Patson, Nikole D; Husband, E Matthew

    2016-05-01

    It has been well established that subject-verb number agreement can be disrupted by local noun phrases that differ in number from the subject head noun phrase. In sentence production, mismatches in the grammatical number of the head and local noun phrases lead to agreement errors on the verb as in: the key to the cabinets are. Similarly, although ungrammaticality typically causes disruption in measures of sentence comprehension, the disruption is reduced when the local noun phrase has a plural feature. Using a forced-choice comprehension question method, we report two experiments that provide evidence that comprehenders were likely to misinterpret the number information on the head noun phrase when morphosyntactic number markings on the local noun phrase and verb did not match the head. These results are consistent with a growing body of research that suggests that comprehenders often arrive at a final interpretation of a sentence that is not faithful to the linguistic input.

  11. The Homomorphic Key Agreement

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    There are various challenges that are faced in group communication, so it is necessary to ensure session key. Key agreement is the fundamental cryptographic primitive for establishing a secure communication. It is a process of computing a shared secret contributed by two or more entities such that no single node can predetermine the resulting value. An authenticated key agreement is attained by combining the key agreement protocol with digital signatures. After a brief introduction to existing key agreement in group communication, Making use of the additive-multiplicative homomorphism in the integer ring defined by Sander and Tschudin: A new protocols, called the homomorphism key agreement, was designed, which can be self-contributory, robust, scalable and applicable in group communication.

    Full Text Available Introduction: The present study is designed to assess the apical seal obtained after root end cavity irrigation with MTAD and retrograde filling with mineral trioxide aggregate (MTA and Biodentine. Materials and Methods: Sixty extracted maxillary central incisors were instrumented and obturated. Apical 3 mm of all the roots were resected and retrograde preparations of 3 mm were made in all the teeth using ultrasonic tips. Thirty root end preparations were irrigated with MTAD for 5 min (Group 1, while 30 were irrigated with saline for 5 min (Group 2. Each main group was subdivided into two subgroups containing 15 samples each. Samples under each subgroup were then filled either with MTA (1A and 2A or Biodentine (1B and 2B. The amount of microleakage was assessed using a UV spectrophotometer. Results: Statistical analysis suggest a significant difference (P < 0.005 between group 1A and 2A and between the groups 1B and 2B (P < 0.1. There was a significant difference (P < 0.005 between group 1A and 1B and also between group 2A and 2B. Conclusion: Irrigation with MTAD significantly improved the apical seal of Biodentine, but it increased the microleakage in MTA-filled root end cavities. Also the apical seal obtained with Biodentine was superior to that obtained with MTA.

    We carried out a histological analysis on bone defects grafted (MTA) treated or not with LED, BMPs and GBR. Benefits of the isolated or combined use these techniques on bone repair have been suggested, but there is no report on their association with LED light. 36 rats were divided into 4 groups each subdivided into 3. Defects on G II and I were filled with the blood clot. G II was further irradiated with LED. G III-IV were filled with MTA+Collagen gel; G IV was further irradiated. LED was applied over the defect at 48 h intervals and repeated for 15 days. Specimens were processed, cut and stained with H&E and Sirius red and underwent histological analysis. The results showed that MTA, due to its characteristics seemed not being directly affected by the LED light. But, the use of LED positively affect bone repair similarly to what was observed on different studies by our team using other biomaterials and laser. It is concluded that MTA seems not be directed affected by the LED light due to it characteristics. However, the beneficial results reported with its usage might be improved by the use of LED PT.

  15. Is patient confidentiality compromised with the electronic health record?: a position paper.

    Science.gov (United States)

    Wallace, Ilse M

    2015-02-01

    In order for electronic health records to fulfill their expected benefits, protection of privacy of patient information is key. Lack of trust in confidentiality can lead to reluctance in disclosing all relevant information, which could have grave consequences. This position paper contemplates whether patient confidentiality is compromised by electronic health records. The position that confidentiality is compromised was supported by the four bioethical principles and argued that despite laws and various safeguards to protect patients' confidentiality, numerous data breaches have occurred. The position that confidentiality is not compromised was supported by virtue ethics and a utilitarian viewpoint and argued that safeguards keep information confidential and the public feels relatively safe with the electronic health record. The article concludes with an ethically superior position that confidentiality is compromised with the electronic health record. Although organizational and governmental ways of enhancing the confidentiality of patient information within the electronic health record facilitate confidentiality, the ultimate responsibility of maintaining confidentiality rests with the individual end-users and their ethical code of conduct. The American Nurses Association Code of Ethics for nurses calls for nurses to be watchful with data security in electronic communications. PMID:25532832

  17. Medical confidentiality versus disclosure: Ethical and legal dilemmas.

    LENUS (Irish Health Repository)

    Agyapong, V I O

    2009-02-01

    A case is described of a fifty year old single man who made disclosures about criminal sexual practices during a psychiatric assessment. In common practice with other professional men, a doctor is under a duty not to disclose, without the consent of his patient, information which he has gained in his professional capacity other than in exceptional circumstances. We discuss the ethical and legal considerations surrounding issues of medical confidentiality and the dilemma that sometimes face clinicians, when they feel obliged, in the public interest, to disclose information they have gained in confidence. Breach of confidences can have deleterious consequences; particularly for the doctor-patient relationship, but failure to disclose in some situations could have serious implications for the well-being of the wider society. Doctors should be aware of the basic principles of confidentiality and the ethical and legal framework around which they are built.

    Science.gov (United States)

    Szekely, D G; Milam, S; Khademi, J A

    1996-01-01

    Computer-based, electronic dental record keeping involves complex issues of patient privacy and the dental practitioner's ethical duty of confidentiality. Federal and state law is responding to the new legal issues presented by computer technology. Authenticating the electronic record in terms of ensuring its reliability and accuracy is essential in order to protect its admissibility as evidence in legal actions. Security systems must be carefully planned to limit access and provide for back-up and storage of dental records. Carefully planned security systems protect the patient from disclosure without the patient's consent and also protect the practitioner from the liability that would arise from such disclosure. Human errors account for the majority of data security problems. Personnel security is assured through pre-employment screening, employment contracts, policies, and staff education. Contracts for health information systems should include provisions for indemnification and ensure the confidentiality of the system by the vendor. PMID:8594098

  19. An efficient steganography method for hiding patient confidential information.

    Al-Dmour, Hayat; Al-Ani, Ahmed; Nguyen, Hung

    2014-01-01

    This paper deals with the important issue of security and confidentiality of patient information when exchanging or storing medical images. Steganography has recently been viewed as an alternative or complement to cryptography, as existing cryptographic systems are not perfect due to their vulnerability to certain types of attack. We propose in this paper a new steganography algorithm for hiding patient confidential information. It utilizes Pixel Value Differencing (PVD) to identify contrast regions in the image and a Hamming code that embeds 3 secret message bits into 4 bits of the cover image. In order to preserve the content of the region of interest (ROI), the embedding is only performed using the Region of Non-Interest (RONI). PMID:25569937

    2015-01-01

    This paper surveys the application of game theory to the economic analysis of international fisheries agreements. The relevance of this study comes not only from the existence of a vast literature on the topic but especially from the specific features of these agreements. The emphasis of the survey...... is on coalition games, an approach that has become prominent in the fisheries economics literature over the last decade. It is shown that coalition games were first applied to international fisheries agreements in the late 1990s addressing cooperative issues under the framework of characteristic...... formation and stability of international fisheries agreements. A key message that emerges from this literature strand is that self-enforcing cooperative management of internationally shared fish stocks is generally difficult to achieve. Hence, the international legal framework and regulations play a...

    2014-05-01

    Full Text Available With the growing number of aging population and a significant portion of that suffering from cardiac diseases, it is conceivable that remote ECG patient monitoring systems are expected to be widely used as Point-of-Care (PoC applications in hospitals around the world. Therefore, huge amount of ECG signal collected by Body Sensor Networks (BSNs from remote patients at homes will be transmitted along with other physiological readings such as blood pressure, temperature, glucose level etc. and diagnosed by those remote patient monitoring systems. It is utterly important that patient confidentiality is protected while data is being transmitted over the public network as well as when they are stored in hospital servers used by remote monitoring systems. In this project, a wavelet based steganography technique has been introduced which combines encryption and scrambling technique to protect patient confidential data. The proposed method allows ECG signal to hide its corresponding patient confidential data and other physiological information thus guaranteeing the integration between ECG and the rest.

    The law of confidentiality of medical information in the occupational setting is undeveloped and subject to change. Nevertheless, when a physician-patient relationship is established, all of the traditional trappings, including the duty to maintain confidences, go along with it. In other settings, such as preemployment physicals, examinees implicitly consent for their "fitness' for the job to be disclosed, but do not assume that specific findings will be disclosed without their informed and written consent. To promote physician automony and worker confidence in the occupational physician, an explicit policy of confidentiality should be developed and agreed to by both management and workers. This policy should spell out the conditions under which specific information will be made available to the employer and should guarantee the confidentiality of all other medical information. Workers should also be given routine access to their medical files, and offered the chance to refute and have amended information in them that they can demonstrate is inaccurate. In short, workers in the occupational setting should, in general, be treated like private patients. Such a policy will satisfy both the law and the ethical standards of physicians, and will promote worker trust in the occupational physician. PMID:956937

    2012-01-01

    The precise nature and scope of healthcare confidentiality has long been the subject of debate. While the obligation of confidentiality is integral to professional ethical codes and is also safeguarded under English law through the equitable remedy of breach of confidence, underpinned by the right to privacy enshrined in Article 8 of the Human Rights Act 1998, it has never been regarded as absolute. But when can and should personal information be made available for statistical and research purposes and what if the information in question is highly sensitive information, such as that relating to the termination of pregnancy after 24 weeks? This article explores the case of In the Matter of an Appeal to the Information Tribunal under section 57 of the Freedom of Information Act 2000, concerning the decision of the Department of Health to withhold some statistical data from the publication of its annual abortion statistics. The specific data being withheld concerned the termination for serious fetal handicap under section 1(1)d of the Abortion Act 1967. The paper explores the implications of this case, which relate both to the nature and scope of personal privacy. It suggests that lessons can be drawn from this case about public interest and use of statistical information and also about general policy issues concerning the legal regulation of confidentiality and privacy in the future.

    2008-04-01

    Full Text Available Background and Aim: Sealing the root canal system is of great importance in endodontic treatment especially in infected teeth. Several materials have been introduced for this purpose. The aim of the present study was to evaluate the sealing ability of MTA as an orthograde root filling material and compare it with laterally condensed gutta-percha with sealer.Materials and Methods: Thirty-six extracted human maxillary central and canine teeth were used in this experimental study. After preparation and surface disinfection with 1% NaOCl solution, the crowns of the teeth were cut at cemento-enamel junction.Roots were randomly divided into four groups: two experimental groups  of 15 roots each (gutta-percha with AH26 sealer and MTA and two control groups of 3 roots each (positive and negative. After root canal preparation and filling, the sealing ability of each technique was assessed by immersion in 1% methylene blue dye for 72 hours. Then the teeth were cleared and the extent of dye penetration was measured with a stereomicroscope. Data were analyzed by T-test with P<0.05 as the level of significance.Results: The results showed that the mean microleakage was 1.1mm (SD=2.1 in the gutta percha group and 3.4mm (SD= 2.1 in the MTA group.This difference was statistically significant (P=0.013.Conclusion: Based on the results of this study, canal obturation with gutta-percha and AH26 sealer may provide a better apical seal compared with MTA. However, further studies on microbial leakage are needed for more precise evaluation of the sealing ability of MTA.

  11. MTA index: a simple 2D-method for assessing atrophy of the medial temporal lobe using clinically available neuroimaging

    Directory of Open Access Journals (Sweden)

    Manuel eMenéndez-González

    2014-03-01

    Full Text Available Background and purpose: Despite a strong correlation between severity of Alzheimer disease (AD pathology and medial temporal lobe atrophy (MTA, its measurement has not been widely used in daily clinical practice as a criterion in the diagnosis of prodromal and probable AD. This is mainly because the methods available to date are sophisticated and difficult to implement for routine use in most hospitals. In this pilot study we aim to describe a novel, simple and objective method for measuring the rate of MTA in relation to the global atrophy using clinically available neuroimaging and describe the rationale behind this method.Description: This method consists of calculating a ratio of 3 regions traced manually on one single coronal MRI slide at the level of the interpeduncular fossa: i the medial temporal lobe region (A; ii the parenchyma within the medial temporal region, that includes the hippocampus and the parahippocampal gyrus -the fimbriae taenia and choroid plexus are excluded- (B; and iii the body of the ipsilateral lateral ventricle (C. Therefore we can compute the ratio Medial Temporal Atrophy index at both sides as follows: MTAi = (A-B x10/C.Conclusions: The MTAi is a simple 2D-method for measuring the relative extent of atrophy in the MTL in relation to the global brain atrophy. This method can be useful for a more accurate diagnosis of AD in routine clinical practice. Further studies are needed to assess the usefulness of MTAi in the diagnosis of early AD, in tracking the progression of AD and in the differential diagnosis of AD with other dementias.

    Full Text Available The information confidentiality and cyber security risk affects the right to confidentiality and privacy of the patient, as regulated in Romania by the Law 46/2002. The manifestation of the cyber security risk event affects the reputation of the healthcare institution and is becoming more and more complex and often due to the: development of network technology, the medical equipment connected to wifi and the electronic databases. The databases containing medical records were implemented due to automation. Thus, transforming data into medical knowledge contribute to a better understanding of the disease. Due to these factors, the measures taken by the hospital management for this type of risk are adapted to the cyber changes. The hospital objectives aim: the implementation of a robust information system, the early threats identifications and the incident reporting. Neglecting this type of risk can generate financial loss, inability to continue providing health care services for a certain period of time, providing an erroneous diagnosis, medical equipment errors etc. Thus, in a digital age the appropriate risk management for the information security and cyber risk represent a necessity. The main concern of hospitals worldwide is to align with international requirements and obtain credentials in terms of data security from the International Organisation for Standardization, which regulates the management of this type of risk. Romania is at the beginning in terms of concerns regarding the management, avoidance and mitigation of information security, the health system being most highly exposed to its manifestation. The present paper examines the concerns of the health system to the confidentiality of information and cyber security risk and its management arrangements. Thus, a set of key risk indicators is implemented and monitored for 2011-2013, using a user interface, a Dashboard, which acts as an early warning system of the manifestation of the

  3. Confidential Communication Through Chaos Encryption in Wireless Sensor Network

    Institute of Scientific and Technical Information of China (English)

    CHEN Shuai; ZHONG Xian-xin

    2007-01-01

    A new byte block cipher algorithm with discrete chaos and Feistel structure has been studied for confidential communication in wireless sensor network to improve security. After permutation, the byte block was encrypted through a Feistel structure in multiple turns and afterwards replaced again. The child keys are the composite sequence of discrete chaos and linear congruence sequences. Both the plain text and cipher text are of 8 bits. The number of keys is alterable. A nonlinear encryption function in the Feistel structure with chaos was constructed. The cipher algorithm was realized in the Micaz node,and the confidential communication experiment in wireless sensor network was completed successfully. Additional ROM memory required for the cipher algorithm is 4144 bytes and an additional RAM memory 61 bytes. The cipher algorithm is nonlinear chaos and the Feistel structure holds the best of the RC6, DES and SKIPJACK cipher algorithms.The result shows that the algorithm needs a little memory and is safe at a high level.

  4. XDS-I outsourcing proxy: ensuring confidentiality while preserving interoperability.

    Science.gov (United States)

    Ribeiro, Luís S; Viana-Ferreira, Carlos; Oliveira, José Luís; Costa, Carlos

    2014-07-01

    The interoperability of services and the sharing of health data have been a continuous goal for health professionals, patients, institutions, and policy makers. However, several issues have been hindering this goal, such as incompatible implementations of standards (e.g., HL7, DICOM), multiple ontologies, and security constraints. Cross-enterprise document sharing (XDS) workflows were proposed by Integrating the Healthcare Enterprise (IHE) to address current limitations in exchanging clinical data among organizations. To ensure data protection, XDS actors must be placed in trustworthy domains, which are normally inside such institutions. However, due to rapidly growing IT requirements, the outsourcing of resources in the Cloud is becoming very appealing. This paper presents a software proxy that enables the outsourcing of XDS architectural parts while preserving the interoperability, confidentiality, and searchability of clinical information. A key component in our architecture is a new searchable encryption (SE) scheme-Posterior Playfair Searchable Encryption (PPSE)-which, besides keeping the same confidentiality levels of the stored data, hides the search patterns to the adversary, bringing improvements when compared to the remaining practical state-of-the-art SE schemes.

There are more domains opening up in the OBS that evidently shows their advantages and their capability to face the future network traffic. However, the concept of OBS is still far from perfection facing issues in case of security threat. The transfer of optical switching paradigm to optical burst switching faces serious downfall in the fields of burst aggregation, routing, authentication, dispute resolution, and quality of service (QoS). This paper deals with employing RC4 (stream cipher) to encrypt and decrypt bursts thereby ensuring the confidentiality of the burst. Although the use of AES algorithm has already been proposed for the same issue, by contrasting the two algorithms under the parameters of burst encryption and decryption time, end-to-end delay, it was found that RC4 provided better results. This paper looks to provide a better solution for the confidentiality of the burst in OBS networks. PMID:24578663

    Rothstein, M.A. [ed.

    1998-09-01

    Few developments are likely to affect human beings more profoundly in the long run than the discoveries resulting from advances in modern genetics. Although the developments in genetic technology promise to provide many additional benefits, their application to genetic screening poses ethical, social, and legal questions, many of which are rooted in issues of privacy and confidentiality. The ethical, practical, and legal ramifications of these and related questions are explored in depth. The broad range of topics includes: the privacy and confidentiality of genetic information; the challenges to privacy and confidentiality that may be projected to result from the emerging genetic technologies; the role of informed consent in protecting the confidentiality of genetic information in the clinical setting; the potential uses of genetic information by third parties; the implications of changes in the health care delivery system for privacy and confidentiality; relevant national and international developments in public policies, professional standards, and laws; recommendations; and the identification of research needs.

    Full Text Available Introduction: Cooperation among nurses is related to Colleague’s Confidentiality Protection, according to Nursing Deontology and their Code of Ethics.The purpose of this study was the evaluation of nursing personnel attitudes, perceptions and behavior towards Colleague’s Confidentiality. Methodology: This study was conducted on the basis of the Master Studies in “Management of health services and crisis management” of University of Peloponnese from July till November of 2011. The sample of the study included nursing personnel of General Hospital of Sparta, of Molai and of Panarkadian Hospital of Tripolis. Based on the study of literature a questionnaire was constructed. Data consistency was tested by Cronbach α (α= 0,81. Specifically, the questionnaire reflected the attitudes and perceptions related to the behavior of the nursing staff regarding the cooperation among them and their collaboration with patients. It also included questions investigating actions made by the participants in case a colleague put in danger patient’s life or risked an infection. Finally, there were questions regarding the participants’ satisfaction from actions taken in case they made a report for a nursing error to the ward they were working. 200 questionnaires were distributed and 177 were finally answered (88.5% respone rate. For the statistical analysis the statistical program SPSS V.16 was used. Results: 9.7% of the participants were men and the rest 90,3% were women. Mean age of the sample was 36,8 years with the lowest to be 20 years old and the highest 58 years old. The majority of the participants (40% said that they had reported an error but they didn’t do it officially. The main reason for non-reporting it was because of the Colleague’s Confidentiality’s Protection. A rate of 48% of the nurses knew Nurses’ Code of Ethics and the law existence supporting it. A rate of 32.5% of the participants considered that by reporting an error, the

    We carried out a histological analysis on surgical bone defects grafted or not with MTA, treated or not with LED, BMPs and GBR. We have used several models to assess the effects of laser on bone. Benefits of the isolated or combined use them on bone healing has been suggested. There is no previous report on their association with LED light. 90 rats were divided into 10 groups. On Groups II and I the defect were filled with the clot. On Group II, were further irradiated. On groups III-VI, defect was filled with MTA + Collagen gel (III); animals of group IV were further irradiated. On groups V and VI, the defects filled with the MTA were covered with a membrane. Animals of Group VI were further irradiated. On Groups VII and VIII a pool of BMPs was added to the MTA and was further irradiated. On groups IX and X, the MTA + BMP graft was covered with a membrane. On group X, the defect was further irradiated. LED (λ850 +/- 10nm, 150mW, A= 0.5cm2, 54s, 0.3W/cm2, 16 J/cm2) was applied at 48 h intervals during 15 days. Specimens were taken, processed, cut and stained with H&E and Sirius red and underwent histological analysis. The results showed that MTA seemed not being affected by LED light. However, its use positively affected healing around the graft. It is concluded that MTA is not affected by the LED light due to it characteristics, but beneficial results with LED usage was found.

  15. Attacker Control and Impact for Confidentiality and Integrity

    CERN Document Server

    Askarov, Aslan

    2011-01-01

    Language-based information flow methods offer a principled way to enforce strong security properties, but enforcing noninterference is too inflexible for realistic applications. Security-typed languages have therefore introduced declassification mechanisms for relaxing confidentiality policies, and endorsement mechanisms for relaxing integrity policies. However, a continuing challenge has been to define what security is guaranteed when such mechanisms are used. This paper presents a new semantic framework for expressing security policies for declassification and endorsement in a language-based setting. The key insight is that security can be characterized in terms of the influence that declassification and endorsement allow to the attacker. The new framework introduces two notions of security to describe the influence of the attacker. Attacker control defines what the attacker is able to learn from observable effects of this code; attacker impact captures the attacker's influence on trusted locations. This ap...

  16. Maglev suspension in soundproofing cabins for confidential talks

    Directory of Open Access Journals (Sweden)

    I.I. Bogolepov

    2010-06-01

    Full Text Available This article discusses the idea of providing sound insulation of the room by using a magnetic suspension. It is based on the invention of the Abrakitov V. E.: sound bridge problem is solved by the avoidance of mechanical contact between the panel and the main structure by a magnetic suspension of sound-insulating vacuum panel. The problem is considered on the example of the cabin for private talks.The implementation of sound insulation from airborne sound is technically uncomplicated task, but there are some problems with the structural component of the sound - the sound energy transfer from box floor to office floor and further through the building structures, sometimes at great distance. Modern methods of eavesdropping can use successfully this way. This paper suggests using a magnetic suspension in soundproof rectangular cabins for confidential talks, which excludes leakage of speech information by more effective isolation of the structural sound. If it is necessary to stop the voice information leakage fundamentally by both air sound and structural sound ways, the authors propose to make a cabin from two steel spherical shells, exhausting all air between the walls and supporting the inner shell by the magnetic suspension in suspended condition. In addition, a spherical cabin is the only effective way of isolation from infrasound.The proposed soundproof rectangular and spherical cabins for confidential talks should be designed, manufactured and tested by experts in the field of acoustic, magnetic suspension, autonomous air regeneration and providing a vacuum. Only in this case the necessary acoustic, technological and operational characteristics of a new hi-tech product will be provided.

    2016-09-01

    Confidentiality is paramount in healthcare, yet according to Danish guidelines, health professionals have to inform parents about their child´s situation until the age of 18 years. This is in contrast to Danish legislation regarding informed consent, where adolescents aged 15 years can consent to treatment. Young people value confidentiality, although they are unaware of the current guidelines. International guidelines on youth-friendly health services recommend split visits and confidential care while at the same time acknowledging parents' caretaking role, especially in adolescents with chronic illness.

  18. Seismic contracts and agreements

    International Nuclear Information System (INIS)

    Some points to consider regarding management of seismic projects within the Canadian petroleum industry were reviewed. Seismic projects involve the integration of many services. This paper focused on user-provider relationships, the project planning process, competitive bid considerations, the types of agreement used for seismic and their implications, and the impact that certain points of control may have on a company: (1) initial estimate versus actual cost, (2) liability, (3) safety and operational performance, and (4) quality of deliverables. The objective is to drive home the point that in today's environment where companies are forming, merging, or collapsing on a weekly basis , chain of command and accountability are issues that can no longer be dealt with casually. Companies must form business relationships with service providers with a full knowledge of benefits and liabilities of the style of relationship they choose. Diligent and proactive management tends to optimize cost, safety and liability issues, all of which have a bearing on the points of control available to the company

    Confidentiality and privacy have always been a vital part of the health care provider-patient relationship. The aim of this study was to identify and analyze the knowledge, attitudes, and awareness of dentists in Croatia concerning patients' confidentiality and privacy and to determine the degree to which they were protecting patients' confidentiality and privacy in everyday practice. Survey data were collected from seventy of the approximately 4,000 dentists in Croatia who had been randomly selected using the registry of the Croatian Chamber of Dental Medicine. Our strategy for data collection included visits to the dental offices and clinics. The data showed that dentists displayed a lack of awareness and had a poor attitude toward respecting patients' rights to confidentiality and privacy. This study indicated the need to educate dentists about their responsibilities and legal obligations. PMID:23486904

    Electronic medical records containing confidential information were uploaded to the cloud. The cloud allows medical crews to access and manage the data and integration of medical records easily. This data system provides relevant information to medical personnel and facilitates and improve electronic medical record management and data transmission. A structure of cloud-based and patient-centered personal health record (PHR) is proposed in this study. This technique helps patients to manage their health information, such as appointment date with doctor, health reports, and a completed understanding of their own health conditions. It will create patients a positive attitudes to maintain the health. The patients make decision on their own for those whom has access to their records over a specific span of time specified by the patients. Storing data in the cloud environment can reduce costs and enhance the share of information, but the potential threat of information security should be taken into consideration. This study is proposing the cloud-based secure transmission mechanism is suitable for multiple users (like nurse aides, patients, and family members). PMID:27059737

  11. WTO confidential: the case of asbestos. World Trade Organization.

    Science.gov (United States)

    Castleman, Barry

    2002-01-01

    The World Trade Organization (WTO), created in 1995, adjudicates "trade disputes" between member nations in cases with great human rights, cultural, environmental, and public health significance. Throughout the process of dispute resolution and even after a case is concluded, very little of what happens is made accessible to the public. However, it is one thing to criticize the WTO for its lack of transparency from outside the process, and another to critically examine what was withheld from disclosure and what dangers that presents. This is the inside story from a scientific adviser to one of the parties in a WTO case, analyzing what happened from a public health point of view. This analysis concludes that the public health justification of banning asbestos was accepted in the end by the economists at the WTO, despite the WTO's bias in favoring the party (Canada) making the free trade challenge (to public health legislation, in this case) in numerous stages of the process, despite the WTO's utter lack of expertise in science, medicine, engineering, and public health, and despite important erroneous statements made to the WTO under the cover of confidentiality. Despite its result, this case illustrates that the WTO's threat to national sovereignty could never withstand the light of day, that the people of the world would reject this dangerous free trade fundamentalism if the limitations and dangers of the process were open for all to see.

    Kelly, Grant; McKenzie, Bruce

    2002-01-01

    We introduce the issues around protecting information about patients and related data sent via the Internet. We begin by reviewing three concepts necessary to any discussion about data security in a healthcare environment: privacy, confidentiality, and consent. We are giving some advice on how to protect local data. Authentication and privacy of e-mail via encryption is offered by Pretty Good Privacy (PGP) and Secure Multipurpose Internet Mail Extensions (S/MIME). The de facto Internet standard for encrypting Web-based information interchanges is Secure Sockets Layer (SSL), more recently known as Transport Layer Security or TLS. There is a public key infrastructure process to 'sign' a message whereby the private key of an individual can be used to 'hash' the message. This can then be verified against the sender's public key. This ensures the data's authenticity and origin without conferring privacy, and is called a 'digital signature'. The best protection against viruses is not opening e-mails from unknown sources or those containing unusual message headers. PMID:12554559

  14. Voluntary agreements in environmental policy

    International Nuclear Information System (INIS)

    A typically voluntary agreement is signed between the authorities and an industrial sector in order to reduce the emission of environmentally harmful substances. There are many different types of agreements. Voluntary agreements are not strictly voluntary, since in the background there is often some kind of ''threat'' about taxation or fees if the industry is unwilling to cooperate. This type of agreements has become popular in many OECD countries during the last decades. In Norway there are only a few agreements of this type. Experience with the use of voluntary agreements as well as research show that they are less cost-effective than market-based instruments such as taxes and quota systems. If there are great restrictions on the use of taxes and quota systems because of information- or measurement problems, or because these instruments are not politically acceptable, then voluntary agreements may be an interesting alternative. Thus, voluntary agreements are best used as a supplement to other instruments in some niche areas of the environmental policy. In some cases, voluntary agreements may be used between two countries or at a regional level, for example within the EU

    The health care system is undergoing major reform, characterized by organized delivery systems (regionalization, decentralization, devolution, etc); shifts in care delivery sites; changing health provider roles; increasing consumer responsibilities; and accountability. Rapid advances in information technology and telecommunications have led to a new type of information infrastructure which can play a major role in this reform. Compatible health information systems are now being integrated and connected across institutional, regional, and sectorial boundaries. In the near future, these information systems will readily be accessed and shared by health providers, researchers, policy makers, health consumers, and the public. SECURITY is a critical characteristic of any health information system. This paper will address three fields associated with SECURITY: confidentiality, integrity, and availability. These will be defined and examined as they relate to specific aspects of Telemedicine, such as electronic integrated records and clinical databases; electronic transfer of documents; as well as data storage and disposal. The guiding principles, standards, and safeguards being considered and put in place to ensure that telemedicine information intrastructures can protect and benefit all stakeholders' rights and needs in both primary and secondary uses of information will be reviewed.

  20. When security and medicine missions conflict: confidentiality in prison settings.

    Science.gov (United States)

    Allen, Scott A; Aburabi, Raed

    2016-06-13

    Purpose - It is a simple fact that prisons cannot exist - practically, legally, ethically or morally - without the support of physicians and other health professionals. Access to adequate healthcare is one of the fundamental measures of the legitimacy of a jail or prison. At the same time, there is a fundamental tension in the missions of the prison and doctor. The primary mission of the prison is security and often punishment. Reform and rehabilitation have intermittently been stated goals of prisons in the last century, but in practice those humane goals have rarely governed prison administrative culture. The primary mission of the physician is to promote the health and welfare of his or her patient. The paper aims to discuss these issues. Design/methodology/approach - At times, what is required to serve the patient's best interest is at odds with the interests of security. Much of the work of the prison physician does not conflict with the operation of security. Indeed, much of the work of the prison physician is allowed to proceed without much interference from the security regime. But given the fundamental discord in the legitimate missions of security vs medicine, conflict between the doctor and the warden is inevitable. Findings - In this paper, the authors consider the example of patient confidentiality to illustrate this conflict, using case examples inspired by real cases from the experience of the authors. Originality/value - The authors provide an ethical and practical framework for health professionals to employ when confronting these inevitable conflicts in correctional settings. PMID:27219904

  6. Intersections of gender and age in health care: adapting autonomy and confidentiality for the adolescent girl.

    Science.gov (United States)

    Pinto, Kristina C

    2004-01-01

    Autonomy and confidentiality are central topics in adolescent health care, both pertaining to findings that nonparent adults often benefit adolescent girls' psychological resilience. Traditionally, autonomy captures a patient's right to self-determine a course of treatment, whereas confidentiality is understood as privacy between doctor and patient. The author proposes a revision of these constructs to accommodate the psychology of adolescent girls in health care contexts through a case study of a 17-year-old girl's hospitalization. In particular, the importance of voice and trust in girls' psychology calls for understanding autonomy as self in relationship and confidentiality as mutual confidence. Suggestions for practice are guided by the premise that girls' health care can foster psychological risk or resilience, depending on the doctor-patient relationship. PMID:14725177

  7. Confidentiality, 'no blame culture' and whistleblowing, non-physician practice and accountability.

    Science.gov (United States)

    White, Stuart M

    2006-12-01

    Confidentiality is a core tenet of medical professionalism, which enables the maintenance of trust in a doctor-patient relationship. However, both the amount of personal data stored and the number of third parties who might access this data have increased dramatically in the digital age, necessitating the introduction of various national data protection acts. Paradoxically, the Freedom of Information Act 2000 allows United Kingdom citizens to access information held by public bodies, including hospitals. Furthermore, the Public Interest Disclosure Act 1998 actively protects physicians who breach their duty of confidentiality in the name of public interest ('whistleblowing'). This article explores the evolution of the law and ethics in this area, and draws attention to the difficulties in balancing confidentiality against freedom of information. In addition, the role and responsibilities of the non-physician anaesthetist are examined. PMID:17219939

  9. Nuclear security information: A balancing act between confidentiality and transparency

    International Nuclear Information System (INIS)

    Full text: Nuclear information security - the control of access to sensitive information as well as classification and control measures for nuclear security information - is one of the principles of nuclear security culture. On the other hand the genera l public should be aware, that security is a key consideration for nuclear plant operation and transports of nuclear material. The internet has influenced society and today in all areas access to information is quite easy and taken for granted. Nuclear security is no exception and general information about security is necessary. It is clear that details relating to sensitive security arrangements cannot be divulged to the general public but the release of appropriate information can be helpful in acquiring public confidence and support for nuclear security. The particular content and mode of disseminating this information is a balancing act between confidentiality and transparency. It may vary according to local and national circumstances, the particular public being addressed and prevailing circumstances and conditions. Taking up examples from the nuclear and the non-nuclear field, the paper will focus on some reflections on what could or should be observed, when giving information in sensitive areas and in particular on nuclear security matters. Reflections such as: When evaluating the pros and cons of a transparent policy in the field of nuclear security and trying to evaluate what information may be disclosed, we have to be aware, that we are acting in the delicate field of the nuclear discussion. Further our behaviour will be compared with the information policy in nuclear safety, where in general absolutely open information is applied. Information in general is spread by Medias. When entering in the information business. we have to understand and care about how the Medias work and behave. We have to decide who will enter in contact with the Medias and which information has to be given to whom, at what time and

  10. Rater agreement in lung scintigraphy

    International Nuclear Information System (INIS)

    Purpose: The PIOPED criteria in their original and revised forms are today's standards in the interpretation of ventilation-perfusion scintigraphy. When the PIOPED criteria are used by experienced raters with training in consensus interpretation, the agreement rates have been demonstrated to be excellent. Our purpose was to investigate the rates of agreement between 2 experienced raters from different hospitals who had no training in consensus interpretation. Material and Methods: The 2 raters investigated a population of 195 patients. This group included 72 patients from a previous study who had an intermediate probability of pulmonary embolism and who had also been examined by pulmonary angiography. Results: The results demonstrated moderate agreement rates with a kappa value of 0.54 (0.45-0.63 in a 95% confidence interval), which is similar to the kappa value of the PIOPED study but significantly lower than the kappa values of agreement rates among consensus-trained raters. There was a low consistency in the intermediate probability category, with a proportional agreement rate of 0.39 between the experienced raters. Conclusion: The moderate agreement rates between raters from different hospitals make it difficult to compare study populations of a certain scintigraphic category in different hospitals. Further investigations are mandatory for accurate diagnosis when the scintigrams are in the category of intermediate probability of pulmonary embolism. (orig.)

  11. Flexible climate agreements after 2012

    International Nuclear Information System (INIS)

    The Kyoto agreement is only a small step towards much stronger and broader commitments and new creativity is needed to further develop a really global climate policy. A flexible approach is necessary to obtain broad participation and substantial reduction of the emissions of greenhouse gases. Flexibility is also important to ease negotiations, to ensure cost-effectiveness and implement a global climate agreement. The US withdrawal from the Kyoto Protocol has rendered the agreement much less effective than the original goal of five per cent reduction of the emission from the industrialized countries. In addition the emissions are increasing much faster in countries that have not committed themselves to the agreement. The agreement runs out in 2012 and should be followed by a new agreement, the negotiations about which are to start up no later than 2005. Attempts by the European Union to begin a discussion about future commitments were very quickly wrecked by the G77 group with strong support from the U.S.A. To formulate a practical climate policy the general goal in the Climate Convention must be interpreted and specified. It may seem impossible to agree upon a long-term goal. But the clarity it provides will be very useful. It will be a guide for short-term goals and a reference for evaluation of success

  17. Cost-Benefit Analysis of Confidentiality Policies for Advanced Knowledge Management Systems

    Energy Technology Data Exchange (ETDEWEB)

    May, D

    2003-03-01

    Knowledge Discovery (KD) processes can create new information within a Knowledge Management (KM) system. In many domains, including government, this new information must be secured against unauthorized disclosure. Applying an appropriate confidentiality policy achieves this. However, it is not evident which confidentiality policy to apply, especially when the goals of sharing and disseminating knowledge have to be balanced with the requirements to secure knowledge. This work proposes to solve this problem by developing a cost-benefit analysis technique for examining the tradeoffs between securing and sharing discovered knowledge.

    Emre Bayram

    2016-01-01

    Full Text Available OBJECTIVE: The aim of this study was to determine the effect of the apical foramen diameter and different application methods of Mineral Trioxide Aggregate (MTA on the fracture resistance of simulated immature teeth using a Universal Testing Machine. MATERIALS AND METHOD: Ninety extracted human teeth were used for the fracture resistance test. The apical foramen was prepared to a diameter of 1.0 mm or 1.4 mm to simulate the open apex of immature teeth. MTA was mixed according to manufacturer's recommendations and placed into the root canals with different apical foramen diameter by four different root filling techniques: retrograde, two-phased orthograde, and ortograde with or without internal matrix. Prepared roots were marked 2 mm below the cemento-enamel junction and embedded in transparent acrylic resin in cylinder moulds. Vertical force was applied along the long axis of the tooth at a speed of 5 mm/min, and the maximum resistance to fracture for each tooth was determined in Newton. A software package was used for the statistical analysis. The data were analyzed by using one-way ANOVA and post-hoc Tukey tests. RESULTS: A statistically significant difference could not be observed between the groups (p>0.05 whereas statistically significant differences were found between the test groups and the control groups (p<0.05. CONCLUSION: There was no significant difference between different vertical root filling techniques in increasing the fracture strength of the teeth. The diameter of the apical foramen did not have a significant effect on the fracture resistance.

  7. Providing integrity, authenticity, and confidentiality for header and pixel data of DICOM images.

    Science.gov (United States)

    Al-Haj, Ali

    2015-04-01

    Exchange of medical images over public networks is subjected to different types of security threats. This has triggered persisting demands for secured telemedicine implementations that will provide confidentiality, authenticity, and integrity for the transmitted images. The medical image exchange standard (DICOM) offers mechanisms to provide confidentiality for the header data of the image but not for the pixel data. On the other hand, it offers mechanisms to achieve authenticity and integrity for the pixel data but not for the header data. In this paper, we propose a crypto-based algorithm that provides confidentially, authenticity, and integrity for the pixel data, as well as for the header data. This is achieved by applying strong cryptographic primitives utilizing internally generated security data, such as encryption keys, hashing codes, and digital signatures. The security data are generated internally from the header and the pixel data, thus a strong bond is established between the DICOM data and the corresponding security data. The proposed algorithm has been evaluated extensively using DICOM images of different modalities. Simulation experiments show that confidentiality, authenticity, and integrity have been achieved as reflected by the results we obtained for normalized correlation, entropy, PSNR, histogram analysis, and robustness.

  12. Wavelet-Based ECG Steganography for Protecting Patient Confidential Information in Point-of-Care Systems.

    Science.gov (United States)

    Ibaida, Ayman; Khalil, Ibrahim

    2013-12-01

    With the growing number of aging population and a significant portion of that suffering from cardiac diseases, it is conceivable that remote ECG patient monitoring systems are expected to be widely used as point-of-care (PoC) applications in hospitals around the world. Therefore, huge amount of ECG signal collected by body sensor networks from remote patients at homes will be transmitted along with other physiological readings such as blood pressure, temperature, glucose level, etc., and diagnosed by those remote patient monitoring systems. It is utterly important that patient confidentiality is protected while data are being transmitted over the public network as well as when they are stored in hospital servers used by remote monitoring systems. In this paper, a wavelet-based steganography technique has been introduced which combines encryption and scrambling technique to protect patient confidential data. The proposed method allows ECG signal to hide its corresponding patient confidential data and other physiological information thus guaranteeing the integration between ECG and the rest. To evaluate the effectiveness of the proposed technique on the ECG signal, two distortion measurement metrics have been used: the percentage residual difference and the wavelet weighted PRD. It is found that the proposed technique provides high-security protection for patients data with low (less than 1%) distortion and ECG data remain diagnosable after watermarking (i.e., hiding patient confidential data) and as well as after watermarks (i.e., hidden data) are removed from the watermarked data.

  17. Form 6 - gas balancing agreement

    International Nuclear Information System (INIS)

    In 1988, a special Committee of the Rocky Mountain Mineral Law Foundation undertook a project to draft a model from gas balancing agreement. This project was initiated at the request of a number of Foundation members who felt that a model form gas balancing agreement would facilitate the negotiation of operating agreement, since gas balancing issues had become sticking points in the process. The Committee was composed of attorneys representing a wide cross-section of the oil and gas industry including both major and independent oil companies, production companies with interstate pipeline affiliates, and private practitioners. The Committee attempted to address the more controversial issues in gas balancing with optional provisions in the Form. To facilitate the negotiation process, the number of optional provisions was minimized. This form may be used as an Appendix to the new A.A.P.L. Form 610-1989 Model Form Operating Agreement. This book includes provision of this Form which are: Ownership of gas production; Balancing of production accounts; Cash balancing upon depletion; Deliverability tests; Nominations; Statements; Payment of taxes; Operating expenses; Overproducing allowable; Payment of leasehold burdens; Operator's liability; Successors and assigns; Audits; Arbitration; and Operator's fees

    From the point of view of deontological ethics, privacy is a moral right that patients are entitled to and it is bound to professional confidentiality. Otherwise, the information given by patients to health professionals would not be reliable and a trustable relationship could not be established. The aim of the present study was to assess, by means of questionnaires with open and closed questions, the awareness and attitudes of 100 dentists working in the city of Andradina, São Paulo State, Brazil, with respect to professional confidentiality in dental practice. Most dentists (91.43%) reported to have instructed their assistants on professional confidentiality. However, 44.29% of the interviewees showed to act contradictorily as reported talking about the clinical cases of their patients to their friends or spouses. The great majority of professionals (98.57%) believed that it is important to have classes on Ethics and Bioethics during graduation and, when asked about their knowledge of the penalties imposed for breach of professional confidentiality, only 48.57% of them declared to be aware of it. Only 28.57% of the interviewees affirmed to have exclusive access to the files; 67.14% reported that that files were also accessed by their secretary; 1.43% answered that their spouses also had access, and 2.86% did not answer. From the results of the present survey, it could be observed that, although dentists affirmed to be aware of professional confidentiality, their attitudes did not adhere to ethical and legal requirements. This stand of health professionals has contributed to violate professional ethics and the law itself, bringing problems both to the professional and to the patient. PMID:19089294

  1. Confidential Deterministic Quantum Communication Using Three Quantum States

    2011-11-01

    Full Text Available A secure quantum deterministic communication protocol is described. The protocol is based on transmission of quantum states from unbiased bases and exploits no entanglement. It is composed form two main components: a quantum quasi secure quantum communication supported by a suitable classical message preprocessing layer. Contrary to many others propositions, it does not require large quantum registers. A security level comparable to classic block ciphers is achieved by a specially designed, purely classic, message pre- and post-processing. However, unlike to the classic communication, no key agreement is required. The protocol is also designed in such a way, that noise in the quantum channel works in advantage to legitimate users improving the security level of the communication.

    Beside biomaterials, Laser phototherapy has shown positive effects as auxiliary therapy in bone repair process, especially when involving large bone losses. The aim of this histological study was to evaluate, by light microscopy, the influence of laser phototherapy on the repair of complete tibial fractures in rabbits treated or not with semi-rigid internal fixation and Mineral Trioxide Aggregate - MTA graft. Twelve Rabbits were randomly divided into four groups with three animals each. After general anesthesia, complete fractures were created in one tibia with a carborundum disk. All animals (groups I-IV) had the fracture stabilized with semi-rigid fixation (wire osteosynthesis - WO). Group I was routinely fixed with WO; groups II and IV fracture was filled by blood clot and MTA implant. In Groups III and IV fracture was filled by blood clot and further irradiated with laser (λ780 nm, 70 mW, CW, Φ = 0.04 cm2, 20.4 J/cm2, per session, t = 300s, 142.8 J/cm2 per treatment). The phototherapy protocol was applied immediately after the surgery and repeated each 48 hours during 15 days. Animal death occurred on the 30th postoperative day. After removal of the specimens, the samples were routinely processed, stained with HE and evaluated by light microscopy. Histologically, the group treated with MTA graft and irradiated with laser showed the fracture filled by a more organized and mature trabecular bone, when compared with all other groups. From the results of the present study, it may be concluded that the association of Laser phototherapy + MTA graft in fractures treated with WO improved bone repair when compared with fractures treated only with WO.

    2011-01-01

    This paper presents two new results on multiple-input multiple-output (MIMO) Gaussian broadcast channels with confidential messages. First, the problem of the MIMO Gaussian wiretap channel is revisited. A matrix characterization of the capacity-equivocation region is provided, which extends the previous result on the secrecy capacity of the MIMO Gaussian wiretap channel to the general, possibly imperfect secrecy setting. Next, the problem of MIMO Gaussian broadcast channels with two receivers and three independent messages: a common message intended for both receivers, and two confidential messages each intended for one of the receivers but needing to be kept asymptotically perfectly secret from the other, is considered. A precise characterization of the capacity region is provided, generalizing the previous results which considered only two out of three possible messages.

The intersection of these areas shows that there is high possibility for confidential data disclosure in organisations with none or ineffective security policy. This paper proposes a strategy for managing the risks of information leakage. We define five levels of controls against posting non-public data on Facebook - security policy, applications installed on employees’ workstations, specific router software or firmware, software in the cloud, Facebook itself. Advantages and disadvantages of every level are evaluated. As a result we propose developing of new control integrated in the social media.

  15. Negotiating climate change agreements - the view from the mineral wool sector

    International Nuclear Information System (INIS)

    Trade associations representing energy-intensive industrial sectors in the UK have negotiated agreements with the Department of the Environment, Transport and the Regions (DETR) to enable their members to receive an 80% rebate on the climate change levy (CCL) providing they meet agreed energy saving targets. Insulation manufacturing is represented by Eurisol and the Mineral Wool Energy Savings Company (MINESCO). Rock wool and glass wool manufacture uses energy for blending, melting, fiberising, curing, cooling, cutting and packaging. However the mineral wool sector has already made significant improvements in energy efficiency over the last 20 years. Confidentiality issues led to Eurisol appointing consultants to advise on how individual plants could achieve further energy savings. Cadogan Consultants developed a strategy that incorporated both qualitative and quantitative issues and allowed the energy saving potential at each site to be identified. MINESCO agreed energy saving targets with the DETR in December 2000, but much work remains to be done

    Auxiliary variables are often used to derive survey weights for point estimation. The weights do not contain enough information for consistent variance estimation and confidence intervals. Standard variance estimators and empirical likelihood confidence intervals rely on the values of the auxiliary variables and on inclusion probabilities. Unfortunately, there are numerous situations when the users do not have access to these variables and probabilities, because of confidentiality issues. We ...

  2. Spatial confidentiality and GIS: re-engineering mortality locations from published maps about Hurricane Katrina

    Directory of Open Access Journals (Sweden)

    Leitner Michael

    2006-10-01

    Full Text Available Abstract Background Geographic Information Systems (GIS can provide valuable insight into patterns of human activity. Online spatial display applications, such as Google Earth, can democratise this information by disseminating it to the general public. Although this is a generally positive advance for society, there is a legitimate concern involving the disclosure of confidential information through spatial display. Although guidelines exist for aggregated data, little has been written concerning the display of point level information. The concern is that a map containing points representing cases of cancer or an infectious disease, could be re-engineered back to identify an actual residence. This risk is investigated using point mortality locations from Hurricane Katrina re-engineered from a map published in the Baton Rouge Advocate newspaper, and a field team validating these residences using search and rescue building markings. Results We show that the residence of an individual, visualized as a generalized point covering approximately one and half city blocks on a map, can be re-engineered back to identify the actual house location, or at least a close neighbour, even if the map contains little spatial reference information. The degree of re-engineering success is also shown to depend on the urban characteristic of the neighborhood. Conclusion The results in this paper suggest a need to re-evaluate current guidelines for the display of point (address level data. Examples of other point maps displaying health data extracted from the academic literature are presented where a similar re-engineering approach might cause concern with respect to violating confidentiality. More research is also needed into the role urban structure plays in the accuracy of re-engineering. We suggest that health and spatial scientists should be proactive and suggest a series of point level spatial confidentiality guidelines before governmental decisions are made

  10. Confidentiality and data sharing: vulnerabilities of the Mexican Genomics Sovereignty Act.

    Science.gov (United States)

    Rojas-Martínez, Augusto

    2015-07-01

    A law known as "Genomic Sovereignty Act", instituted in 2011, regulates research on the human genome in Mexico. This law establishes Government regulations for the exportation of DNA samples from Mexican nationals for population genetics studies. The Genomic Sovereignty Act protects fundamental human values, as confidentiality and non-discrimination based on personal genetic information. It also supports the development of the genome-based medical biotechnology and the bio-economy. Current laws for the protection of the genomic confidentiality, however, are inexplicit and insufficient, and the legal and technological instruments are primitive and insufficient to safeguard this bioethical principle. In addition, this law may undermine efforts of the national and international scientific communities to cooperate with big-data analysis for the development of the genome-based biomedical sciences. The argument of this article is that deficiencies in the protection of the confidentiality of genomic information and limitations in data sharing severely weaken the objectives and scope of the Genomic Sovereignty Act. In addition, the Act may compromise the national biomedical development and the international cooperation for research and development in the field of human genomics. PMID:25990230

  11. Embedding patients confidential data in ECG signal for healthcare information systems.

    Science.gov (United States)

    Ibaida, Ayman; Khalil, Ibrahim; Al-Shammary, Dhiah

    2010-01-01

    In Wireless tele-cardiology applications, ECG signal is widely used to monitor cardiac activities of patients. Accordingly, in most e-health applications, ECG signals need to be combined with patient confidential information. Data hiding and watermarking techniques can play a crucial role in ECG wireless tele-monitoring systems by combining the confidential information with the ECG signal since digital ECG data is huge enough to act as host to carry tiny amount of additional secret data. In this paper, a new steganography technique is proposed that helps embed confidential information of patients into specific locations (called special range numbers) of digital ECG host signal that will cause minimal distortion to ECG, and at the same time, any secret information embedded is completely extractable. We show that there are 2.1475 × 10(9) possible special range numbers making it extremely difficult for intruders to identify locations of secret bits. Experiments show that percentage residual difference (PRD) of watermarked ECGs can be as low as 0.0247% and 0.0678% for normal and abnormal ECG segments (taken from MIT-BIH Arrhythmia database) respectively.

  14. Attitudes towards informed consent, confidentiality, and substitute treatment decisions in southern African medical students: a case study from Zimbabwe.

    Science.gov (United States)

    Hipshman, L

    1999-08-01

    This study explored the attitudes of biomedical science students (medical students) in a non-Western setting towards three medical ethics concepts that are based on fundamental Western culture ethical principles. A dichotomous (agree/disagree) response questionnaire was constructed using Western ethnocentric culture (WEC) based perspectives of informed consent, confidentiality, and substitute decision-making. Hypothesized WEC-Biased responses were assigned to the questionnaire's questions or propositions. A number of useful responses (169) were obtained from a large, cross-sectional, convenience sample of the MBChB students at the University of Zimbabwe Medical School. Statistical analysis described the differences in response patterns between the student's responses compared to the hypothesized WEC-Biased response. The effect of the nine independent variables on selected dependent variables (responses to certain questionnaire questions) was analyzed by stepwise logistic regression. Students concurred with the hypothesized WEC-Biased responses for two-thirds of the questionnaire items. This agreement included support for the role of legal advocacy in the substitute decision-making process. The students disagreed with the hypothesized WEC-Biased responses in several important medical ethics aspects. Most notably, the students indicated that persons with mental dysfunctions, as a class, were properly considered incompetent to make treatment decisions. None of the studied independent variables was often associated with students' responses, but training year was more frequently implicated than either ethnicity or gender. In order to develop internationally and culturally relevant medical ethics standards, non-Western perspectives ought to be acknowledged and incorporated. Two main areas for further efforts include: curriculum development in ethics reasoning and related clinical (medico-legal) decision-making processes that would be relevant to medical students from

    Peripheral neuropathy is a dose-limiting side effect of anticancer treatment with the microtubule-targeted agents (MTAs), paclitaxel and epothilone B (EpoB); however, the mechanisms by which the MTAs alter neuronal function and morphology are unknown. We previously demonstrated that paclitaxel alters neuronal sensitivity, in vitro, in the presence of nerve growth factor (NGF). Evidence in the literature suggests that NGF may modulate the neurotoxic effects of paclitaxel. Here, we examine whether NGF modulates changes in neuronal sensitivity and morphology induced by paclitaxel and EpoB. Neuronal sensitivity was assessed using the stimulated release of calcitonin gene-related peptide (CGRP), whereas morphology of established neurites was evaluated using a high content screening system. Dorsal root ganglion cultures, maintained in the absence or presence of NGF, were treated from day 7 to day 12 in culture with paclitaxel (300nM) or EpoB (30nM). Following treatment, the release of CGRP was stimulated using capsaicin or high extracellular potassium. In the presence of NGF, EpoB mimicked the effects of paclitaxel: capsaicin-stimulated release was attenuated, potassium-stimulated release was slightly enhanced and the total peptide content was unchanged. In the absence of NGF, both paclitaxel and EpoB decreased capsaicin- and potassium-stimulated release and the total peptide content, suggesting that NGF may reverse MTA-induced hyposensitivity. Paclitaxel and EpoB both decreased neurite length and branching, and this attenuation was unaffected by NGF in the growth media. These differential effects of NGF on neuronal sensitivity and morphology suggest that neurite retraction is not a causative factor to alter neuronal sensitivity. PMID:26883566

    Full Text Available Metal oxide photocatalysts K4Ce2M10O30 (M=Ta, Nb capable of responding to visible light were synthesized by conventional high temperature solid-state reaction. The photocatalysts have an appropriate band gap energy ca. 1.8–2.3 eV and excellent chemical potential level to evolve H2 from aqueous solutions containing a sacrificial electron donor (Na2SO3 under visible light irradiation (λ>420 nm without any co-catalyst. When they were loading with Pt, RuO2 and NiOx, the activities for evolving H2 were prompted markedly. By SEM and TEM investigations, it can be seen that these loading metal and metal oxides are dispersed on the surface of photocatalysts K4Ce2M10O30 (M=Ta, Nb in diameter of about 10–30 nm particles, especially the NiOx loading even formed double layered structure with metal nickel (Ni and metal oxide (NiO. The reasons for the increasing activities after these loading may be attributable to facilitate electron migrating from the conduction band of K4Ce2M10O30 (M=Ta, Nb to the Pt, RuO2 and NiOx nanoparticles, which function as H2 production sites on the surface of catalysts. The same phenomenon appears on the solid solution K4Ce2Ta10−xNbxO30 (x=0–10 with loading RuO2.

  15. Confidentiality and the physician-patient relationship -- ethical reflections from a surgical waiting room.

    Clark, Peter A

    2002-11-01

    The physician-patient relationship is the primary focus of ethics in medicine. It is both a personal and a professional relationship that is founded on trust, confidence, dignity and mutual respect. Trust is the bridge to the physician-patient relationship, and the burden is on the physician not only to expect the patient's trust but also to build a solid foundation upon which the patient can place his or her trust. Great strides have been made by physicians in refining the physician-patient relationship especially in understanding and respecting the patients' right of self-determination regarding medical decision-making and protecting their rights of privacy and confidentiality. However, further refinements are needed on both sides regarding this relationship. Breaches of confidentiality are occurring in places like surgical waiting rooms and as a result, the physician-patient relationship is being damaged. This article identifies some legitimate concerns and offers some concrete solutions so that the physician-patient relationship can be further refined and the virtues and rights that support it can be reinforced.

  16. Contractual obligations and the sharing of confidential health information in sport.

    Anderson, L

    2008-09-01

    As an employee, a sports doctor has obligations to their employer, but also professional and widely accepted obligations of a doctor to the patient (in this case the individual team member). The conflict is evident when sports doctors are asked by an athlete to keep personal health information confidential from the coach and team management, and yet both doctor and athlete have employment contracts specifying that such information shall be shared. Recent research in New Zealand shows that despite the presence of an employment contract, there appears to be a wide range of behaviours among sports doctors when an athlete requests that information about them be kept from team management. Many seem willing to honour requests to keep health information about the athlete confidential, thereby being in breach of the employment contract, while others insist on informing team management against the wishes of the athlete. There are a number of potential solutions to this dilemma from forcing doctors to meet their contractual obligations, to limiting the expectations of the employment contract. This paper suggests that at times it may be appropriate to do both, making the position of the doctor clearer and supporting the ability of this group to resist pressure by coaches and management through having a robust code of ethics.

    Full Text Available In healthcare industry, the patient\\'s medical data plays a vital role because diagnosis of any ailments is done by using those data. The high volume of medical data leads to scalability and maintenance issues when using health-care provider\\'s on-site picture archiving and communication system (PACS and network oriented storage system. Therefore a standard is needed for maintaining the medical data and for better diagnosis. Since the medical data reflects in a similar way to individuals’ personal information, secrecy should be maintained. Maintaining secrecy can be done by encrypting the data, but as medical data involves images and videos, traditional text based encryption/decryption schemes are not adequate for providing confidentiality. In this paper, we propose an algorithm for securing the DICOM format medical archives by providing better confidentiality and maintaining their integrity. Our contribution in this algorithm is of twofold: (1 Development of Improved Chaotic based Arnold Cat Map for encryption/decryption of DICOM files and (2 Applying a new hash algorithm based on chaotic theory for those encrypted files for maintaining integrity. By applying this algorithm, the secrecy of medical data is maintained. The proposed algorithm is tested with various DICOM format image archives by studying the following parameters i PSNR - for quality of images and ii Key - for security.

  18. A data-hiding technique with authentication, integration, and confidentiality for electronic patient records.

    2002-03-01

    A data-hiding technique called the "bipolar multiple-number base" was developed to provide capabilities of authentication, integration, and confidentiality for an electronic patient record (EPR) transmitted among hospitals through the Internet. The proposed technique is capable of hiding those EPR related data such as diagnostic reports, electrocardiogram, and digital signatures from doctors or a hospital into a mark image. The mark image could be the mark of a hospital used to identify the origin of an EPR. Those digital signatures from doctors and a hospital could be applied for the EPR authentication. Thus, different types of medical data can be integrated into the same mark image. The confidentiality is ultimately achieved by decrypting the EPR related data and digital signatures with an exact copy of the original mark image. The experimental results validate the integrity and the invisibility of the hidden EPR related data. This newly developed technique allows all of the hidden data to be separated and restored perfectly by authorized users. PMID:11936596

  20. Analyzing rater agreement manifest variable methods

    CERN Document Server

    von Eye, Alexander

    2014-01-01

    Agreement among raters is of great importance in many domains. For example, in medicine, diagnoses are often provided by more than one doctor to make sure the proposed treatment is optimal. In criminal trials, sentencing depends, among other things, on the complete agreement among the jurors. In observational studies, researchers increase reliability by examining discrepant ratings. This book is intended to help researchers statistically examine rater agreement by reviewing four different approaches to the technique.The first approach introduces readers to calculating coefficients that allow one to summarize agreements in a single score. The second approach involves estimating log-linear models that allow one to test specific hypotheses about the structure of a cross-classification of two or more raters'' judgments. The third approach explores cross-classifications or raters'' agreement for indicators of agreement or disagreement, and for indicators of such characteristics as trends. The fourth approach compa...
