    2016-01-01

    Objective Mineral trioxide aggregate (MTA) cements contain two types of particles, namely Portland cement (PC) (nominally 80% w/w) and bismuth oxide (BO) (20%). This study aims to determine the particle size distribution (PSD) of PC and BO found in MTA. Materials and methods The PSDs of ProRoot MTA (MTA-P) and MTA Angelus (MTA-A) powder were determined using laser diffraction, and compared to samples of PC (at three different particle sizes) and BO. The non-linear least squares method was used to deconvolute the PSDs into the constituents. MTA-P and MTA-A powders were also assessed with scanning electron microscopy. Results BO showed a near Gaussian distribution for particle size, with a mode distribution peak at 10.48 μm. PC samples milled to differing degrees of fineness had mode distribution peaks from 19.31 down to 4.88 μm. MTA-P had a complex PSD composed of both fine and large PC particles, with BO at an intermediate size, whereas MTA-A had only small BO particles and large PC particles. Conclusions The PSD of MTA cement products is bimodal or more complex, which has implications for understanding how particle size influences the overall properties of the material. Smaller particles may be reactive PC or unreactive radiopaque agent. Manufacturers should disclose particle size information for PC and radiopaque agents to prevent simplistic conclusions being drawn from statements of average particle size for MTA materials.

  14. Structure, expression and functions of MTA genes.

    Science.gov (United States)

    Kumar, Rakesh; Wang, Rui-An

    2016-05-15

    Metastatic associated proteins (MTA) are integrators of upstream regulatory signals with the ability to act as master coregulators for modifying gene transcriptional activity. The MTA family includes three genes and multiple alternatively spliced variants. The MTA proteins neither have their own enzymatic activity nor have been shown to directly interact with DNA. However, MTA proteins interact with a variety of chromatin remodeling factors and complexes with enzymatic activities for modulating the plasticity of nucleosomes, leading to the repression or derepression of target genes or other extra-nuclear and nucleosome remodeling and histone deacetylase (NuRD)-complex independent activities. The functions of MTA family members are driven by the steady state levels and subcellular localization of MTA proteins, the dynamic nature of modifying signals and enzymes, the structural features and post-translational modification of protein domains, interactions with binding proteins, and the nature of the engaged and resulting features of nucleosomes in the proximity of target genes. In general, MTA1 and MTA2 are the most upregulated genes in human cancer and correlate well with aggressive phenotypes, therapeutic resistance, poor prognosis and ultimately, unfavorable survival of cancer patients. Here we will discuss the structure, expression and functions of the MTA family of genes in the context of cancer cells.

    Sen, Nirmalya; Gui, Bin; Kumar, Rakesh

    2014-12-01

    Although the functional significance of the metastasic tumor antigen (MTA) family of chromatin remodeling proteins in the pathobiology of cancer is fairly well recognized, the physiological role of MTA proteins continues to be an understudied research area and is just beginning to be recognized. Similar to cancer cells, MTA1 also modulates the expression of target genes in normal cells either by acting as a corepressor or coactivator. In addition, physiological functions of MTA proteins are likely to be influenced by its differential expression, subcellular localization, and regulation by upstream modulators and extracellular signals. This review summarizes our current understanding of the physiological functions of the MTA proteins in model systems. In particular, we highlight recent advances of the role MTA proteins play in the brain, eye, circadian rhythm, mammary gland biology, spermatogenesis, liver, immunomodulation and inflammation, cellular radio-sensitivity, and hematopoiesis and differentiation. Based on the growth of knowledge regarding the exciting new facets of the MTA family of proteins in biology and medicine, we speculate that the next burst of findings in this field may reveal further molecular regulatory insights of non-redundant functions of MTA coregulators in the normal physiology as well as in pathological conditions outside cancer.

  20. Confidentiality in psychological practice: a decrepit concept?

    Science.gov (United States)

    McMahon, M; Knowles, A D

    1995-11-01

    Although the principle of confidentiality in the relationship between psychologists and client has been vaunted, and is emphasised in the Australian Psychological Society's Code of Professional Conduct (the APS code; 1994), the confidentiality of this relationship is circumscribed by the absence of legal protections, the ethical beliefs of psychologists, institutional practices, and the provisions of the APS code itself. Lack of privilege in judicial proceedings, and statutory obligations to report certain types of behaviour, mandate breaches of confidentiality in some circumstances. Ethical beliefs of psychologists may support disclosure, especially where it is believed that there is danger of serious physical harm to the client or others. Multidisciplinary teams and institutional settings require the exchange of information for optimal delivery of services. Recent amendments to the APS code may require disclosure without the client's consent when a client is believed to be suicidal. Such developments, when considered at all, are typically regarded as exceptions to a general obligation of confidentiality. However, discussion of exceptions presupposes agreement on fundamental principle: the significance of, and rationale for, confidentiality in the psychologist-client relationship. It is argued in this paper that the obligation of confidentiality has been assumed rather than vigorously analysed and empirically explored. A critical examination of this obligation is the most appropriate starting point for the rehabilitation of contemporary principles of confidentiality in the psychologist-client relationship.

    Mineral trioxide aggregate (MTA) is a multi-application material used in endodontics. It is a mixture of a refined Portland cement and bismuth oxide and trace amounts of SiO₂, CaO, MgO, K₂SO₄, and Na₂SO₄. MTA powder is mixed with supplied sterile water in a 3:1 powder/liquid. Hydrated MTA has an initial pH of 10.2, which rises to 12.5 three hours after mixing. There are several materials derived from MTA such as Endo-CPM Sealer, Ortho MTA, MTA-Fillapex, DiaRoot BioAggregate, MTA Bio, light-cured MTA, tricalcium silicate, and iRoot SP. The purpose of this article is to review MTA-like materials.

  2. Confidentiality and personal integrity.

    Science.gov (United States)

    Edgar, A

    1994-06-01

    This paper uses the social theory of Erving Goffman in order to argue that confidentiality should be understood in relation to the mundane social skills by which individuals present and respect specific self-images of themselves and others during social interaction. The breaching of confidentiality is analysed in terms of one person's capacity to embarrass another, and so to expose that person as incompetent. Respecting confidentiality may at once serve to protect the vulnerable from an unjust society, and yet also protect the guilty from just accusation. Ethical reasoning about confidentiality must therefore recognize the dangers of prejudice and violence inherent in decisions to breach or to respect confidentiality. Case studies are used to illustrate the efficacy of this account, culminating with analyses of three examples from the UKCC document Confidentiality.

    Full Text Available The principle of confidentiality is one of the highlights of the institution of arbitration. Its application is not uniform in the national legislation. The parties to an arbitration agreement may experience various unpleasant situations such as unwanted disclosure of issues they wanted to keep secret, although they had relied on the fact that the private nature of arbitration would protect them from prying eyes and unwanted third parties. In this article we take a brief foray into national and international legislation, analyzing the way in which the principle of confidentiality is applied.

    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.

    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...

    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

    Full Text Available Background and Aim: Today several materials have been used for root- end filling in endodontic surgery. 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. Conclusion: Based on the results of this study, there were no significant differences in leakage among the four

    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 MTA than in those cultured in the presence of 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.

  17. [Mineral trioxide aggregate (MTA) a success story in apical surgery].

    von Arx, Thomas

    2016-01-01

    The objective of apical surgery is to retain teeth with persistent apical pathosis following orthograde root canal treatment if endodontic non-surgical revision is difficult or associated with risks, or is even declined by the patient. Since the most frequent cause of recurrent apical disease is bacterial reinfection from the (remaining) root canal system, the bacteria-tight root-end filling is the most important step in apical surgery. In the early 1990s, mineral trioxide aggregate (MTA) was developed at the Loma Linda University in California/USA. Preclinical studies clearly showed that MTA has a high sealing capability, a good material stability and an excellent biocompatbility. Multiple experimental studies in animals highlighted the mild tissue reactions observed adjacent to this material. Furthermore, histological analysis of the periapical regions demonstrated a frequent deposition of new cementum not only onto the resection plane (cut dentinal surface), but also directly onto MTA. For these reasons, MTA is considered a bioactive material. In 1997 MTA was cleared for clinical use in patients. Multiple prospective clinical and randomized studies have documented high and constant success rates of MTA-treated teeth in apical surgery. A recently published longitudinal study showed that MTA-treated teeth remained stable over five years; hence the high healed rates documented after one year are maintained during long-term observation.

    In this series, the Bulletin aims to explain the role of the Ombuds at CERN by presenting practical examples of misunderstandings that could have been resolved by the Ombuds if he had been contacted earlier. Please note that, in all the situations we present, the names are fictitious and used only to improve clarity.    Jane* came to the Ombuds to share her concerns about the actions of Mike*, one of her senior colleague supervisors, and insisted on the absolute confidentiality. The Ombuds promised to keep the information confidential following the terms of his mandate. During the discussion it appeared that the whole group was affected by the situation, spending a lot of time discussing how to resolve the problem instead of focusing on their main responsibilities. The risks for the Organization seemed very high and could possibly endanger the safety of the operations.  On one side, the Ombuds believed that it was essential to bring this matter to the attention of senior managem...

    The aim of this study was to compare the in vitro cytotoxicity of white mineral trioxide aggregate (MTA), MTA Fillapex® and Portland cement (PC) on human cultured periodontal ligament fibroblasts. Periodontal ligament fibroblast culture was established and the cells were used for cytotoxic tests after the fourth passage. Cell density was set at 1.25 X10 4 cells/well in 96-well plates. Endodontic material extracts were prepared by placing sealer/cement specimens (5x3mm) in 1mL of culture medium for 72 h. The extracts were then serially two-fold diluted and inserted into the cell-seeded wells for 24, 48 and 72 h. MTT assay was employed for analysis of cell viability. Cell supernatants were tested for nitric oxide using the Griess reagent system. MTA presented cytotoxic effect in undiluted extracts at 24 and 72 h. MTA Fillapex® presented the highest cytotoxic levels with important cell viability reduction for pure extracts and at ½ and ¼ dilutions. In this study, PC did not induce alterations in fibroblast viability. Nitric oxide was detected in extract-treated cell supernatants and also in the extracts only, suggesting presence of nitrite in the soluble content of the tested materials. In the present study, MTA Fillapex displayed the highest cytotoxic effect on periodontal ligament fibroblasts followed by white MTA and PC.

  2. 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.

    Full Text Available During recent decades, the third person intervention in human artificial insemination has created new hopes for infertile couples. However these new progresses have propounded new ethical and legal concerns for families. One of them is confidentiality regarding gamete donor's identity, and its disclosure to the future child and others. Of course, negligence to this ethical issue would produce a big barrier for efficient health care services."nFor compiling this article we searched different websites including Pubmed, Ovid, Elsevier, Google and etc and the resulting articles were investigated carefully. "nIn this article, the history of gamete donation in different countries is reviewed initially and the mentioned reasons for anonymity with that of disclosure are compared. "nBecause of the different cultures and values of various societies, it is not justifiable to propose a unique method regarding this issue; however, there have to be clear rules in this regard, in each country. In order to facilitate this process, pretreatment counseling courses should be established to explain different aspects of this issue for the recipients.

  6. Fetal privacy and confidentiality.

    Science.gov (United States)

    Botkin, J R

    1995-01-01

    With the advent of new and better contraceptive methods and the ability to facilitate and manipulate fertilization and gestation, couples will gain greater control over their fertility. Once a pregnancy has been established or an in vitro embryo created, the ability to evaluate the embryo and fetus will increase dramatically with progress in human genetic research. Preconception and preimplantation genetic testing and screening are now possible, and the technology to perform prenatal screening early in gestation is advancing rapidly. Nonsurgical methods facilitate induced abortion with a relatively lower degree of trauma upon the woman undergoing the procedure. These capabilities may all be used to enable and even encourage the genetic selection of future children. Despite the ethical concerns associated with prenatal testing and abortion, these services will continue to be an integral aspect of reproductive medicine. As technology advances, however, it will be possible to test and screen for conditions which do not produce serious defects. Genetic conditions which produce relatively mild impacts upon health will be identifiable in the embryo or fetus, while late-onset conditions and genetic factors which have only a probability of affecting health will also be located in the fetal genome. Prospective parents may therefore soon have the capability of selecting their most desirable embryo in vitro, or terminating all undesirable fetuses in vivo until the preferred child is delivered. The medical profession must take some responsibility for establishing guidelines on the use of reproductive technology. The standards of practice for the medical profession must reflect the results of a broad social debate over competing moral values. The author develops an argument for legal and ethical limitations on the application of prenatal testing and screening technology, suggesting that for some medical conditions, respect for the privacy and confidentiality of the fetus

    2009-04-01

    The histological success of mineral trioxide aggregate (MTA) pulpotomy for treatment of irreversible pulpitis in human teeth as an alternative treatment was investigated in this study. Fourteen molars which had to be extracted were selected from patients 16-28 years old. The selection criteria include carious pulp exposure with a history of lingering pain. After isolation, caries removal and pulp exposure, MTA was used in pulpotomy treatment. Patients were evaluated for pain after 24 h. Two patients were lost from this study. Twelve teeth were extracted after 2 months and were assessed histologically. Recall examinations confirmed that none of the patients experienced pain after pulpotomy. Histological observation revealed that all samples had dentin bridge formation completely and that the pulps were vital and free of inflammation. Although the results favour the use of MTA as a pulpotomy material, more studies with larger samples and a longer recall period are suggested to justify the use of MTA for treatment of irreversible pulpitis in human permanent teeth.

    Hashem, Ahmed Abdel Rahman; Hassanien, Ehab E

    2008-01-01

    The ability of two mineral trioxide aggregate (MTA) compounds and Intermediate Restorative Material (IRM) to seal large furcation perforations were evaluated using a dye-extraction leakage method. The furcation perforations were repaired with and without the use of internal matrix before placement of repair material. Eighty extracted human mandibular first molars were divided into positive (n = 10), negative (n = 10), and three experimental groups (n = 20) according to the repair material used. Each experimental group was divided into two subgroups (n = 10) according to whether internal matrix was used or not. Dye leakage was tested from an orthograde direction, and dye extraction was performed using full concentration nitric acid. Dye absorbance was measured at 550 nm using spectrophotometer. ProRoot MTA (Maillfer, Dentsply, Switzerland) with and without internal matrix and MTA-Angelus (Angelus, Londrina, PR, Brazil) with internal matrix showed the least dye absorbance. IRM (Caulk, Dentsply, Milford, DE) without internal matrix showed the highest dye absorbance. IRM with internal matrix and MTA-Angelus without internal matrix had insignificant difference and came at intermediate level between the other groups.

    F. Sasani

    2004-09-01

    Full Text Available Statement of Problem: Nowadays Mineral Trioxide aggregate (MTA is widely used for root end fillings, pulp capping, perforation repair and other endodontic treatments.Investigations have shown similar physical and chemical properties for Portland cement and Root MTA with those described for MTA.Purpose: The aim of this in vitro study was to evaluate the tissue reaction to implanted MTA, Portland cement and Root MTA in the mandible of cats.Materials and Methods: Under asepsis condition and general anesthesia, a mucoperiosteal flap, following the application of local anesthesia, was elevated to expose mandibular symphysis. Two small holes in both sides of mandible were drilled. MTA, Portland cement and Root MTA were mixed according to the manufacturers, recommendation and placed in bony cavities. In positive control group, the test material was Zinc oxide powder plus tricresoformalin. In negative control group, the bony cavities were left untreated. After 3,6 and 12 weeks, the animals were sacrificed and the mandibular sections were prepared for histologic examination under light microscope. The presence and thickness of inflammation, presence of fibrosis capsule, the severity of fibrosis and bone formation were investigated. The data were submitted to Exact Fisher test, chi square test and Kruskal-Wallis test for statistical analysis.Results: No statistically significant differences were found in the degree of inflammation,presence of fibrotic capsule, severity of fibrosis and inflammation thickness between Root MTA, Portland cement and MTA (P>0.05. There was no statistical difference in boneformation between MTA and Portland cement (P>0.05. However, bone formation was not found in any of the Root MTA specimens and the observed tissue was exclusively of fibrosis type.Conclusion: The physical and histological results observed with MTA are similar to those of Root MTA and Portland cement. Additionally, all of these three materials are biocompatible

    Full Text Available Objective  To analyze the clinical significance of MTA1 overexpression in cervical cancer and bioinformatically screen the potential treatment targets from the gene network correlated with MTA1 overexpression. Methods  SPSS software package was used to analyze the correlation of MTA1 with clinical metastasis and pathological grade of cervical cancer based on TCGA-CESC data set. The edgeR software was used to screen the gene set whose expression was correlated with MTA1 in cervical cancer at a global transcriptional level. DAVID platform was adopted to identify the enriched biological functions of the gene set significantly correlated with MTA1 expression. The transcriptional regulation network of the gene set was constructed with STRING online platform and Cytospace softwares to identify the key regulators. Results  TCGA-CESC database assay showed a significant positive correlation of MTA1 expression with clinical metastasis of cervical cancer (P<0.01. There was a gene set in which gene expression was closely correlated with MTA1 level. Functional enrichment of the gene set indicated that cancer pathways, stem cell pathways, cell migration, cell differentiation, etc. were closely linked to MTA1-correlated malignant behaviors of cancers. Bioinformatical screening showed that Agt, Acta1, Fpr2, Pmch and RGS18, which are correlated with MTA1 expression in cervical cancer, were the key regulators in differentially expressed gene sets. And these genes were located to the GPCR pathway. Conclusions  MTA1 overexpression is significantly correlated with clinical metastasis of cervical cancer and paralleled with the activation of gene regulation involved in stem cell pathway, cytokine receptor signaling, cell migration and differentiation pathways. These genes are correlated with MTA1 expression and potential treatment targets in cervical cancer and should be further experimentally evaluated in the future.

  20. Is there sufficient evidence to support the long-term efficacy of mineral trioxide aggregate (MTA) for endodontic therapy in primary teeth?

    Science.gov (United States)

    Anthonappa, R P; King, N M; Martens, L C

    2013-03-01

    Several papers have been published to illustrate the effectiveness of mineral trioxide aggregate (MTA) as a pulpotomy medicament. Most of these reports do not offer a critical assessment on the data quality. Therefore, this review evaluated whether the currently available evidence is of an appropriate quality to support the long-term effectiveness of MTA as a pulpotomy medicament in primary molars using a standardized assessment criterion. A comprehensive literature search of human clinical outcome studies, which employed MTA as a pulpotomy medicament in primary teeth, was conducted using the MEDLINE database. Two independent observers rated these articles using the standardized assessment criteria. Furthermore, based on the initial sample mentioned in the individual studies and the sample included for the final analysis, the drop-out rates were calculated. Twenty-two studies were included for quality assessment with an excellent interobserver agreement. None of the 22 studies obtained grade A, four studies attained grade B1, five were graded B2 and 13 received grade C. Based on the assessment criteria employed, there was no evidence that MTA was better than present materials and techniques as a pulpotomy medicament. Furthermore, given the low quality of data, it is highly desirable to establish standard requisites for conducting and reporting on pulp therapy studies in primary teeth so as to benefit both researchers and clinicians to produce high-quality studies that are comparable and to prevent the misuse of clinical material and resources.

    Purpose. To compare the biocompatibility and antimicrobial effectiveness of the new Fast-Set MTA (FS-MTA) with ProRoot MTA (RS-MTA). Methods. The agar overlay method with neutral red dye was used. L929 mouse fibroblast cells were cultured. The liquid and oil extracts and solid test material were placed on the agar overlay, four samples for each material. Phenol was used as the positive control and cottonseed oil and MEM extracts were used as negative controls. Cytotoxicity was examined by measuring the zones of decolorization and evaluating cell lysis under an inverted microscope using the established criteria after 24 and 48 hours. The antimicrobial test was performed using the Kirby-Bauer disk-diffusion method against S. mutans, E. faecalis, F. nucleatum, P. gingivalis, and P. intermedia. The size of the zone of inhibition was measured in millimeters. Results. There was no zone of decolorization seen under or around the test materials for FS-MTA and RS-MTA at 24 and 48 hours. The antimicrobial test demonstrated no inhibitory effect of FS-MTA or RS-MTA on any bacterial species after 24 and 48 hours. Conclusions. There was no cytotoxicity or bacterial inhibition observed by the new Fast-Set MTA when compared to the ProRoot MTA after setting. PMID:28303246

    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. PMID:27504400

    2012-01-01

    This case report describes the periradicular healing and resorption of an unintentional extrusion of mineral trioxide aggregate (MTA) in an open-apex central incisor. A 22-year old female with a symptomatic open-apex right maxillary central incisor associated with a periradicular lesion was referred for evaluation and treatment. After chemomechanical debridement, the apical third of the root canal was filled with MTA to create an apical plug. Postoperative radiographs showed the extrusion of MTA into the periradicular lesion. The tooth was then restored with a post and crown. At the 2-year follow-up, the tooth was asymptomatic and radiographs revealed complete healing of the periradicular area. At the 7-year follow-up, complete resorption of the extruded MTA was evident. The results of this case study indicate that complete resorption of extruded MTA is possible in the long term; however, the extrusion of MTA in open-apex tooth should still be avoided.

    2005-01-01

    To compare the expression level of metastasis associated-1 (MTA1) gene in high and low metastatic human osteosarcoma cell lines and examine the relationship of MTA 1 expression and the metastasis potentiality of osteosarcoma cells, the expression of MTA1 in MG-63 osteosarcoma cell lines with high and low metastasis potential was detected by semiquantitative TR-PCR. Boyden chamber invasion assay was used to evaluate the invasive capacity in vitro in two osteosarcoma cell lines. The low metastasis MG-63 cells were transfected with MTA1 full-length cDNA expression plasmid by lipofectamine and the changes of MTA1 expression and in vitro invasion potential were examined after the transfection. Our results showed that MG63cell line with high metastasis potential expressed significantly higher MTA1 than that of MG63 cells with low metastasis as reavealed by RT-PCR. The invasion potential of low metastasis MG63 cell line was increased after MTA 1 gene transfection. It is concluded that there may be a relationship between MTA 1 and invasive potentiality of human osteosarcoma cells, and the mechanism of MTA1 in osteosarcoma metastasis and its possible role in associated gene therapy deserve further study.

    2006-01-01

    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.

    Since the initial recognition of the metastasis-associated protein 1 (MTA1) as a metastasis-relevant gene approximately 20 years ago, our appreciation for the complex role of the MTA family of coregulatory proteins in human cancer has profoundly grown. MTA proteins consist of six family members with similar structural units and act as central signaling nodes for integrating upstream signals into regulatory chromatin-remodeling networks, leading to regulation of gene expression in cancer cells. Substantial experimental and clinical evidence demonstrates that MTA proteins, particularly MTA1, are frequently deregulated in a wide range of human cancers. The MTA family governs cell survival, the invasive and metastatic phenotypes of cancer cells, and the aggressiveness of cancer and the prognosis of patients with MTA1 overexpressing cancers. Our discussion here highlights our current understanding of the regulatory mechanisms and functional roles of MTA proteins in cancer progression and expands upon the potential implications of MTA proteins in cancer biology and cancer therapeutics.

    This study evaluated the influence of the exposure of mineral trioxide aggregate (MTA) - with and without calcium chloride (CaCl2) -to phosphate-buffered saline (PBS) on apical microleakage. Sixty root segments were divided into 4 experimental groups (n=15). Apical cavities were filled with MTA with or without CaCl2, and the root canals dressed with a moistened cotton pellet or PBS: 1) MTA/cotton pellet; 2) MTA/PBS; 3) MTA+ 10%CaCl2/cotton pellet; 4) MTA+10%CaCl2/PBS. After 2 months, E. faecalis penetration was analyzed along the apical plugs. Samples were observed weekly for 70 days, and leakage was detected by turbidity of the medium in contact with the root segment. Teeth in the control groups (n=2) were either made completely impermeable or kept without an apical plug. The Kaplan-Meier method was used to analyze survival and the Logrank test was used to compare the survival curves (pMTA sealing ability, but cannot prevent bacterial leakage. The addition of CaCl2 to the MTA did not improve MTA sealing ability.

  10. [Professional confidentiality and the family].

    Louvrier, P

    2006-09-01

    The roots of " doctor-patient privilege " or professional confidentiality go back to the Greek island of Cos - Hippocrates' birthplace. The Cos school advocated silence about what the doctor might learn during his visits. In 1868 the Napoleonic Criminal Code sanctioned those who divulged secrets that were entrusted to them by virtue of their profession or estate. The [Belgian medical association's] Code of Professional Ethics extends the bounds of professional confidentiality to include everything that the doctor sees, has knowledge of, learns of, ascertains, discovers, or surprises. Confidentiality as a matter of public policy is relative. It is a tool for the preservation of values, allowing access to health care without fear of divulgation. This leads to possible conflicts of values, conflicts between two duties involving a value that can be protected only to the detriment of another value. The family's rights are specified in Belgium's law on patient's rights, to wit: indirect consultation of the medical file after an individual's death and representation of a patient who is not able to exercise her/his rights her/himself. Silence is nevertheless the rule. The care that an illness calls for generally forces the doctor to make certain disclosures to the patient's family about the state of the illness. This usually goes no farther if the ailment is benign. However, in some sensitive situations (HIV, alcoholism, and divorce), the doctor must bear in mind that the patient may oppose the disclosure of any and all information. A good understanding of the foundations of professional confidentiality, informing the patient, and the doctor's own human qualities should make it possible to get hitherto stalled situations to move forward. The patient remains the doctor's primary focus.

    Full Text Available Objective: In a cavity prepared through endodontic surgery, application of a material to provide apical seal and prevent bacterial and tissue exudates is of great importance. The purpose of this study was to compare the sealing ability of Biocalex with white MTA, gray MTA, and amalgam as root-end fillings.Materials and Methods: Sixty-six single-rooted extracted human teeth were cleaned, shaped, and obturated with gutta-percha. The root apices were resected and 3 mm deep retrograde cavity was prepared. The teeth were assigned randomly into four groups of 15 teeth each and retrofilled with Biocalex, gray MTA, white MTA, and amalgam. Six teeth served as positive and negative controls. All root surfaces, except the ending part, were covered with two layers of nail polish. The roots were then stored in 2% methylene blue for 72 hours and embedded in polyester resin. The teeth were sectioned buccolingually and maximum extent of dye penetration was evaluated through a stereomicroscope. Statis-tical analysis was carried out by one way ANOVA and Tukey test.Results: Biocalex showed significantly less leakage compared to the other three materials P<0.05. White MTA showed significantly lower amount of leakage as Compared to gray MTA and amalgam P<0.05.Conclusion: The findings of this study showed that retrograde filling with Biocalex can achieve proper sealing ability and this material can be used as an alternative for MTA and amalgam.

    Background: It is important to have a replicable easy method for monitoring atrophy progression in Alzheimer's disease. Volumetric methods for calculating hippocampal volume are time-consuming and commonly used in research. Visual assessments of medial temporal lobe atrophy (vaMTA) is a rapid method for clinical use. This method has not been tested in a large non-demented population in comparison with volumetry measurements. Since hippocampal volume decreases with time even in normal aging there is also a need to study the normal age differences of medial temporal lobe atrophy. Purpose: To compare visual assessment of medial temporal lobe atrophy (vaMTA) with hippocampal volume in a healthy, non-demented elderly population. To describe normal ageing using vaMTA. Material and Methods: Non-demented individuals aged 60, 66, 72, 78, 81, 84, and {>=}87 years old were recruited from the Swedish National study on Ageing and Care in Kungsholmen (SNAC-K), Sweden. Standard magnetic resonance imaging (MRI) scans, vaMTA, and calculations of hippocampal volumes were performed in 544 subjects. Results: Significant correlation (rs = -0.32, P < 0.001, sin; and rs = -0.26, P < 0.001, dx) was found between hippocampal volume measurements and vaMTA. In normal ageing, almost 95% of {<=}66-year-olds had a medial temporal lobe atrophy (MTA) score {<=}1, with possible scores ranging from 0 to 4. Subjects aged 72, 78, and 81 years scored {<=}2, while the two oldest age groups had scores {<=}3. Conclusion: There was a highly significant correlation between volumetric measurements of the hippocampus and MTA scoring. In normal ageing, there is increasing MTA score. For non-demented elderly individuals {<=}70 years, an MTA score of 0-1 may be considered normal, compared with MTA {<=}2 for 70-80-years and MTA 3 for >80-year-old individuals.

    2010-06-01

    Full Text Available Abstract Background 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. Methods 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. Results 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. Conclusions 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.

    The members of the metastasis-associated protein (MTA) family play pivotal roles in both physiological and pathophysiological processes, especially in cancer development and metastasis, and their role as master regulators has come to light. Due to the fact that they were first identified as crucial factors in estrogen receptor-mediated breast cancer metastasis, most of the early studies focused on their hormone-dependent functions. However, the accumulating evidence shows that the members of MTA family are deregulated in most, if not all, the cancers studied so far. Therefore, the levels as well as the activities of the MTA family members are widely accepted as potential biomarkers for diagnosis, prognosis, and predictors of overall survival. They function differently in different cancers with specific mechanisms. p53 and HIF-1α appear to be the respectively common upstream and downstream regulator of the MTA family in both development and metastasis of a wide spectrum of cancers. Here, we review the expression and clinical significance of the MTA family, focusing on hormone-independent cancers. To illustrate the molecular mechanisms, we analyze the MTA family-related signaling pathways in different cancers. Finally, targeting the MTA family directly or the pathways involved in the MTA family indirectly could be invaluable strategies in the development of cancer therapeutics.

  18. 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

    2007-09-01

    Since breast cancer and its associated metastasis are a global health problem and a major cause of mortality among women, research efforts to understand the development, morphogenesis, and functioning of the mammary gland are a high priority. Myriad signaling pathways, transcription factors, and associated transcriptional coregulators have been identified in both normal functioning and neoplastic transformation of the mammary gland. The discovery of the metastasis tumor antigen 1 (MTA1) gene, its overexpression in cancer and metastasis and its subsequent identification as an integral part of the chromatin remodeling complex heralded extensive research on its physiological role. Subsequent identification of additional gene family members, namely MTA1s, MTA2, and MTA3, and their functions in the cell has resulted in the establishment of the significance of the MTA family. The role of these proteins in modulating hormonal responses in normal mammary glands and in breast cancer has resulted in their identification as important molecular markers and potential therapeutic targets.

    2012-07-01

    Full Text Available Abstract Background Presented is the method “Detection and Outline Error Estimates” (DOEE for assessing rater agreement in the delineation of multiple sclerosis (MS lesions. 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.

  17. Confidentiality in psychotherapy: Some of actual dilemmas

    Directory of Open Access Journals (Sweden)

    2004-01-01

    Full Text Available The article examines confidentiality principle from different perspectives: as the factor which plays a very important part in developing a productive therapist-client relationship, ethical and, in many countries, legal issue. Ways to maintain confidentiality in therapy are stated, as well as situations in which it is inevitably limited. Three dilemmas concerning confidentiality are explained and discussed. The first is when one should speak and when one should be silent and what we should do when we are in two minds. The second is whether the client should be informed about confidentiality limitations at the very beginning, or when the need arises during the treatment. The third is whether confidentiality limitation (when a client poses a threat to himself or to the society should be legally regulated, as it is being done in many western countries.

    2007-04-01

    The use of a suitable substance that prevents egress of potential contaminants into the periapical tissues is important in endodontic surgery. The aim of the present study was to compare the marginal adaptation of three root-end filling materials (white mineral trioxide aggregate (MTA), grey MTA and Portland cement), using scanning electron microscopy. Seventy-five single-rooted extracted human teeth were used. The canals were instrumented and filled with gutta-percha. Following root-end resection and cavity preparation, root-end cavities were filled with white MTA, grey MTA or Portland cement. Using a diamond saw, roots were longitudinally sectioned into two halves. Under scanning electron microscopy, the gaps between the material and dentinal wall were measured. The data were analysed using Kruskal-Wallis test. The mean of the gap in grey MTA, white MTA and Portland cement was 211.6, 349 and 326.3 microm, respectively. The results indicate that the gap between grey MTA and the dentinal wall is less than other materials, but there was no significant difference between the materials tested in this study (P > 0.05).

    2006-01-01

    The purpose of this study was to study the histologic changes in the dental pulp following pulpotomy with Mineral Trioxide Aggregate (MTA) and Calcium hydroxide. Pulpotomies were performed on premolar teeth that were to be extracted for orthodontic reasons. The radicular pulp was capped with either MTA or Calcium hydroxide and restored with IRM. The teeth were extracted at 4 and 8 week intervals, fixed in 10% formalin and then kept in 5% nitric acid for 28 days for demineralization. Longitudinal sections were then prepared and viewed under light microscope. The pulps capped with MTA (at the end of 4 weeks and 8 weeks) showed dentin bridge formation which was more homogenous and continuous with the original dentin when compared to the pulps capped with calcium hydroxide. The pulpal inflammation was also less in the MTA group as compared to the calcium hydroxide group at the end of 4 and 8 weeks.

  4. Global transcriptional profiling reveals Streptococcus agalactiae genes controlled by the MtaR transcription factor

    Directory of Open Access Journals (Sweden)

    Cvek Urska

    2008-12-01

    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. These findings

    This study assessed the influence of mineral trioxide aggregate (MTA) on adaptive immune responses. BALB/c mice were immunized with heat-killed Fusobacterium nucleatum (Fn) in MTA or other control adjuvants, and serum IgG responses to Fn were measured. Either Fn- or Peptostreptococcus anaerobius (Pa)-reactive memory T cells (Tm) were pre-incubated in vitro with/without MTA and restimulated with Fn or Pa. Tm proliferation and cytokine production were assessed. Compared to control groups, IgG-antibody responses were upregulated in mice immunized with Fn in MTA in a similar manner to animals immunized with Fn in Freund's adjuvant or aluminum hydroxide adjuvant. While MTA did not affect the upregulated expression of IL-10, TNF-α or RANKL by Tm, it suppressed the proliferation of Pa- or Fn-Tm and inhibited their production of Th1- or Th2-signature cytokines. MTA upregulated the adaptive humoral immune responses, but had little or no effect on pro- or anti-inflammatory cytokine production by Tm. PMID:18718367

    The aim of the present study was to verify the long-term cytotoxic effects of the MTA Fillapex and to compare them with AH Plus. Dissolution rate and pH were also evaluated. Human osteoblast cells were incubated with elutes of fresh specimens from AH Plus and MTA Fillapex, and with elutes of the same specimens for 4 successive weeks. Elute's pH was evaluated at each time point. A multiparametric cell viability assay was performed. For dissolution rate, ISO methodology was used. The results were analyzed by one-way analysis of variance, complemented with the Tukey post-test (p0.05). After 1 week, AH Plus became non-cytotoxic on all three evaluated parameters. Conversely, MTA Fillapex remained severely and mildly cytotoxic over the entire experimental period (pMTA Fillapex at all time points (p>0.05). The pH of AH Plus was significantly lower than MTA Fillapex at the second and third week (pMTA Fillapex remained cytotoxic after 4 weeks and its cytotoxicity may be related to the high dissolution rate of this material.

    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 MTA presented the lowest, similar to the control (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.

    Pathological changes in pulp and periapical tissues are addressed by endodontic treatment. The material used in this treatment must be biocompatible. The aim of this study is to compare the skin reaction of Calcium Enriched Mixture (CEM) and Mineral Trioxide Aggregate (MTA) produced in Iran on rabbit. Sixteen male newzeland albino rabbits weighting 2 kg were used. The animals back hair was shaved, 24 hours before application of each material. The material was applied on two sites (2 × 2 cm) while the third site was used as control. All sites were covered by gauze and bandaged for 4 hours. Then the material's remnants were washed off the sites of application. Observations were performed in 1, 24, 48 and 72 hours after removing the materials. Erythematous surface areas were measured by the morphometric method. After sacrificing animals the skins were dissected and the specimens were prepared for histological evaluation. There were significant differences between CEM and MTA in erythematous surface areas at 1, 24 and 48 hours after removing the materials (pMTA and control sample (p=0.0001) and between MTA and CEM (p=0.035). There was no significant difference between control and CEM (p>0.05). The average erythematous surface areas were wider in MTA sites than CEM sites. As a conclusion it seems that biocompatibility of CEM could be more than MTA.

    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.

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

    Directory of Open Access Journals (Sweden)

    Wu Meng

    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.

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

    Damgård, Ivan Bjerre; Damgård, Kasper Lyneborg; Nielsen, Kurt;

    We report on the design and implementation of a system that uses multiparty computation to enable banks to benchmark their customers' confidential performance data against a large representative set of confidential performance data from a consultancy house. The system ensures that both the banks......' and the consultancy house's data stays confidential, the banks as clients learn nothing but the computed benchmarking score. In the concrete business application, the developed prototype help Danish banks to find the most efficient customers among a large and challenging group of agricultural customers with too much...... debt. We propose a model based on linear programming for doing the benchmarking and implement it using the SPDZ protocol by Damgård et al., which we modify using a new idea that allows clients to supply data and get output without having to participate in the preprocessing phase and without keeping...

    The repressive Nucleosome Remodeling and histone Deacetylation (NuRD) complex remodels the chromatin structure by coupling ATP-dependent remodeling activity with histone deacetylase function and plays important roles in regulating gene transcription, DNA damage repair and chromatin assembly. The complex is composed of six subunits: Metastasis Associated proteins MTA1/2/3 initially recruit histone chaperones RBBP4/7 followed by the histone deacetylases HDAC1/2 forming a core complex. Further association of the CpG-binding protein MBD2/3, p66α/β and the ATP-dependent helicase CDH3/4 constitutes the NuRD complex. Recent structural studies on truncated human proteins or orthologous have revealed that the stoichiometry of the MTA1-RBBP4 complex is 2:4. This study reports expression and purification of the intact human MTA2-RBBP7 complex using HEK293F cells as expression system. In analogy with findings on the Drosophila NuRD complex, we find that also the human MTA-RBBP can be isolated in vitro. Taken together with previous findings this suggests, that MTA-RBBP is a stable complex, with a central role in the initial assembly of the human NuRD complex. Refined 3D volumes of the complex generated from negative stain electron microscopy (EM) data reveals an elongated architecture that is capable of hinge like motion around the center of the particle.

    Physicochemical properties of pozzolan Portland cement were compared to ProRoot MTA and MTA BIO. To test the pH, the samples were immersed in distilled water for different periods of time. After the pH analysis, the sample was retained in the plastic recipient, and the electrical conductivity of the solution was measured. The solubility and radiopacity properties were evaluated according to specification 57 of the American National Standard Institute/American Dental Association (ANSI/ADA). The statistical analyses were performed using ANOVA and Tukey's test at a 5% level of significance. Pozzolan Portland cement exhibited pH and electrical conductivity mean values similar to those of the MTA-based cements. The solubilities of all tested materials were in accordance with the ANSI/ADA standards. Only the MTA-based cements met the ANSI/ADA recommendations for radiopacity. It might be concluded that the pH and electrical conductivity of pozzolan Portland cement are similar to and comparable to those of MTA-based cements.

    Full Text Available Introduction: Encountering environmental situations that have an adverse effect on the properties of Mineral Trioxide Aggregate (MTA is inevitable and unfortunately common. In many cases MTA does not set and the clinician is forced to apply this cement again. This occurrence may affect the outcome of endodontic treatments such as perforation repair. Therefore, strategies should be considered to overcome this matter. Various studies have been conducted that mixed several substances with MTA to reverse the adverse effects on this material but still we face this problem. The Hypothesis: In this paper, we propose a hypothesis that mixing MTA with phosphate buffered solution (PBS may reverse the adverse environmental effects and may help us overcome this clinical problem. Evaluation of the Hypothesis: PBS is a synthetic solution containing phosphate which is commonly used for mimicking in vivo situations in laboratory studies. Considering that some studies have shown that when MTA encounters tissue fluids containing phosphorous its properties improve, we suggest that mixing this cement with PBS can at least reverse the adverse effect of the environment. It should be noted that the better the properties of these cements, the better the outcome of treatment can be.

    Dental materials based on Portland cement, which is used in the construction industry have gained popularity for clinical use due to their hydraulic properties, the interaction with tooth tissue and their antimicrobial properties. The antimicrobial properties are optimal in vitro. However in clinical use contact with blood may affect the antimicrobial properties. This study aims to assess whether antimicrobial properties of the Portland cement-based dental cements such as mineral trioxide aggregate (MTA) are also affected by contact with blood present in clinical situations. ProRoot MTA, a Portland cement-based dental cement was characterized following contact with water, or heparinized blood after 1 day and 7 days aging. The antimicrobial activity under the mentioned conditions was assessed using 3 antimicrobial tests: agar diffusion test, direct contact test and intratubular infection test. MTA in contact with blood was severely discoloured, exhibited an additional phosphorus peak in elemental analysis, no calcium hydroxide peaks and no areas of bacterial inhibition growth in the agar diffusion test were demonstrated. ProRoot MTA showed limited antimicrobial activity, in both the direct contact test and intratubular infection test. When aged in water ProRoot MTA showed higher antimicrobial activity than when aged in blood. Antimicrobial activity reduced significantly after 7 days. Further assessment is required to investigate behaviour in clinical situations. PMID:28128328

    One of the main disadvantages of MTA is its long setting time which could result in higher solubility and microleakage, producing a failed treatment. Studies have shown that the addition of bioactive glass may decrease the setting time. The aim of this study is to evaluate the compressive strength, setting time, solubility and radiopacity of a MTAlike experimental cement to which different percentage of wollastonite and bioactive glass are added. White MTA Angelus® was used as control; an experimental MTA-like cement (ExpC) was prepared using white Portland cement with 20wt% of Bi2O3; three wollastonite cement composites were prepared adding 10, 20 and 30wt% of wollastonite to ExpC, and three more adding the same proportions of bioactive glass. Compressive strength was tested according to ADA 30; radiopacity, setting time and solubility were tested according to ISO 6876. SEM observations of the surface were made after the solubility test. Compressive strength, setting time, solubility and radiopacity were reduced as the wollastonite increased; solubility increased with the addition of bioactive glass. The surfaces of MTA Angelus® and ExpC were smoother than Wollastonite and Bioactive glass groups. Addition of wollastonite and bioactive glass improved the physical properties of a MTA-like experimental cement, reducing the setting time with good solubility percentages, which would be an advantage in its clinical use.

    This study analyzed the quality of obturation and physical properties of MTA Fillapex and AH Plus sealer. A sample of 30 human maxillary central incisors were instrumented with Protaper until a F5 (50/05) file. Both sealers were mixed with Rhodamine-B dye to allow visualization on a confocal laser-scanning microscope (CLSM). Next, the canals were filled using the single cone technique. After setting, all samples were sectioned at 2, 4, and 6 mm from the apex. CLSM was used to analyze the gaps and sealer penetration into the dentinal tubules. All samples were scanned 10 µm below the dentin surface and images were recorded at 100× magnification using the fluorescent mode. Additionally, the solubility, flowability and setting time of the sealers were evaluated. All the measured quantities of the examined materials were evaluated for significant differences by means of statistical analysis. The CLSM analysis of the MTA Fillapex showed the highest percentage of gaps at all sections (P = 0.0001). Physical tests revealed adequate properties for both sealers except for a higher solubility of the MTA Fillapex (P = 0.0001). The MTA Fillapex presented flowability and intratubular penetration similar to the AH Plus. Nevertheless, the MTA Fillapex sealer presented a higher solubility and considerable quantity of gaps between the sealer/dentin interface in relation to the AH Plus sealer. Clinicians must take into consideration, the quality of endodontic sealers as it is essential in the outcome of the root canal filling.

    $^{\\rm {180m}}$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.

    The aim of this study was to compare the in vitro sealing ability of ProRoot MTA, ProRoot MTA (Tooth-Coloured Formula), ordinary Portland cement and white Portland cement when used as root-end filling materials. Twenty-four single-rooted human premolars were prepared and obturated using standard techniques, then retrofilled with the test materials. The prepared teeth were immersed in 1% methylene blue dye for 72 hours and then assessed for dye leakage. The depth of dye penetration was measured and expressed as a percentage of the length of the retrofilling. Data was analysed using ANOVA and Fisher's Least Significant Test (LSD) (p cements, it is reasonable to consider Portland cement as a possible substitute for MTA as a root-end filling material. However, further tests, especially in vivo biocompatibility tests, need to be conducted before Portland cement can be recommended for clinical use.

    The aim of this study was to compare the biocompatibility of Endocem Zr(®) and ProRoot MTA(®) by histopathologic analysis in a canine model of pulpotomy. This study utilized 39 teeth of two beagle dogs. The exposed pulp tissues were treated by pulpotomy using ProRoot MTA (n=19) or Endocem Zr (n=20). After 8 weeks, the teeth were extracted and processed with hematoxylin-eosin staining for histologic evaluation. Most of the specimens in both groups developed a calcific barrier at the pulp amputation site and formed an odontoblast layer. However, some of the Endocem Zr specimens showed less calcific barrier formation with a greater inflammatory response and less odontoblast layer formation when compared with the ProRoot MTA specimens. ProRoot MTA and Endocem Zr specimens developed a calcific barrier; however, ProRoot MTA was more biocompatible than Endocem Zr.

    Full Text Available The study examined the conditions under which lay people and health professionals living in Chile find it acceptable for a physician to break confidentiality to protect the wife of a patient with a sexually transmitted disease (STD. One hundred sixty-nine lay persons, 10 physicians, 17 psychologists, and 11 paramedical professionals indicated the acceptability of breaking confidentiality in 48 scenarios. The scenarios were all possible combinations of five factors: disease severity (severe, lethal; time taken to discuss this with the patient (little time, much time; patient’s intent to inform his spouse about the disease (none, one of these days, immediately; patient’s intent to adopt protective behaviors (no intent, intent; and physician’s decision to consult an STD expert (yes, no, 2 x 2 x 3 x 2 x 2. The study also compared Chilean and French views, using data gathered previously in France. A cluster analysis conducted on the overall set of raw data revealed groups of participants that found breaking confidentiality “always acceptable” (9%, requiring “consultation with an expert” (5%, “depending on the many circumstances” (70%, and “never acceptable” (11%”. Despite clear differences in legislation and official codes of ethics between their two countries, Chilean and French lay people did not differ much in their personal convictions regarding the circumstances in which patient confidentiality can be broken or must not be broken. By contrast, Chilean physicians, in agreement with their code of ethics, were much less supportive than French physicians of complete respect of patient confidentiality in all cases

    Pulpotomy is the most performed and controversial therapeutic in pediatric dentistry. Formocresol is known to have a toxic effect on living tissues, a mutagenic and carcinogenic potential with a systemic uptake of formocresol via pulpotomized teeth, other alternative products have been investigated. 40 molars were pulpotomized using Micro Mega Mineral Trioxide Aggregate (MM-MTA), which eliminates the need for the use of formocresol. The effects of this material were evaluated both clinically and radiographically. Post-operative control examinations were performed at 1, 6, 12, and 18 months trying to detect spontaneous or stimulated pain, pathological tooth mobility, abscesses or fistulas, internal or external pathological tooth resorption, periapical bone destruction, or canal obliteration. Pain was absent at 18 months post operatively. Thirty six molar treated with the MM-MTA didn't show any mobility or pain, one molar presented a pathological resorption and one molar presented an abscess without a fistula at 12 month. The observations were compared to others related to formocresol, ferric sulfate, MTA, and laser pulpotomies, using the Chi-square test x2. The abundance of positive result strongly demonstrate that the MM-MTA pulpotomy on carious temporary molars is a promising technique.

    Full Text Available Introduction: This case report conveys the prognosis of partial pulpotomy treatment of complicated crown fractures in maxillary permanent incisors using white Mineral Trioxide Aggregate (wMTA or calcium hydroxide in a 9 year-old boy. Case report: The patient was referred to the clinic with complicated crown fractures in both maxillary central incisors due to trauma. Partial pulpotomy was done in both teeth. Calcium hydroxide was selected as a conventional pulp capping agent for tooth number 11 and wMTA was selected for tooth number 21. Unfortunately, 3 months later, the patient had a secondary trauma to tooth number 11 necessitating endodontic treatment, fiber-post and strip-crown restoration. Six months later, discoloration was observed in tooth number 21. The colored material including wMTA and the dentin was removed under operating microscope and the restoration was renewed. Microbiological evaluation of the removed material showed negative culture for aerobic and anaerobic bacteria, and fungus. The tooth number 21 remained vital and a dentin bridge was confirmed clinically and radiographically at 12 and 24 months follow-up visits and there was no further esthetic problem. Conclusion: As a result, it can be concluded that the use of wMTA for partial pulpotomy needs to be reconsidered for esthetical reasons.

    Full Text Available ABSTRACT 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.

    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...

    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...

    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 MTA HP had significantly higher bond strength than White MTA (p MTA HP showed better push-out bond strength than its predecessor, White MTA; however, Biodentine had higher dislodgment resistance than both MTA formulations.

    2016-01-01

    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.

    2016-01-01

    Introduction Vital pulp therapy is a major contributor in the preservation of primary dentition after caries affliction. Introduction of mineral trioxide aggregate (MTA) has revolutionized such treatment. Aim The aim of our study was to evaluate and correlate the effects of MTA clinically and radiographically on pulpotomized primary molars till their exfoliation or extraction followed by histological evaluation. Study design This is an observational study. Materials and methods A total of 25 teeth were selected from 5- to 8-year-old children requiring pulp therapy on the basis of inclusion and exclusion criterion. The teeth were treated by conventional pulpotomy technique under aseptic conditions using MTA and were immediately restored with stainless steel crown. The teeth were assessed postoperatively till 36 months. The exfoliated or extracted teeth were examined histologically. Results The pulpotomized teeth were vital with no adverse clinical findings during the observation period. After 3 months, one tooth showed internal resorption, but the same was not observed after 12 months. Pulp canal obliteration was seen in three cases. At the end of the study, five teeth were exfoliated and one tooth was extracted for maintaining arch symmetry. The histological examination of extracted tooth revealed the presence of healthy pulp and the area of true calcification. Remaining exfoliated teeth presented dentin bridge formation. Statistics Frequencies and percentages were used for descriptive statistics. Fisher’s exact tests were used to see the difference between clinical and radiological findings. The probability value was fixed at 5% level of significance. Conclusion The response of pulp in primary teeth to MTA was favorable in all cases from clinical and radiographic perspective, and histological evaluation confirmed the observation.

    The addition of chlorhexidine (CHX) to a resinous experimental Mineral Trioxide Aggregate (E-MTA) based root-end filling material is an alternative to boost its antimicrobial activity. However, the influence of chlorhexidine on the properties of this material is unclear. The aim of this study was to evaluate the influence of 2% chlorhexidine on the pH, calcium ion release and setting time of a Bisphenol A Ethoxylate Dimethacrylate/Mineral Trioxide Aggregate (Bis-EMA/MTA) based dual-cure experimental root-end filling material (E-MTA), in comparison with E-MTA without the addition of CHX and with conventional white MTA (W-MTA). The materials were placed in polyethylene tubes, and immersed in deionized water to determine pH (digital pH meter) and calcium ion release (atomic absorption spectrometry technique). The setting time of each material was analyzed using Gilmore needles. The data were statistically analyzed at a significance level of 5%. E-MTA + CHX showed an alkaline pH in the 3 h period of evaluation, the alkalinity of which decreased but remained as such for 15 days. The pH of E-MTA + CHX was higher than the other two materials after 7 days, and lower after 30 days (p MTA to levels statistically similar to W-MTA. E-MTA showed shorter initial and final setting time, compared with W-MTA (p MTA prevented setting of the material. The addition of CHX to E-MTA increased its pH and calcium ion release. However, it also prevented setting of the material.

    Achievable secrecy rate regions for the general 3-receiver broadcast channel with one common and one confidential message sets are established. We consider two setups: (i) when the confidential message is to be sent to two of the receivers and the third receiver is an eavesdropper; and (ii) when the confidential message is to be sent to one of the receivers and the other two receivers are eavesdroppers. We show that our secrecy rate regions are optimum for some special cases.

    Full Text Available Cloud Computing creates a dynamic resource sharing platform. Using cloud technologies such as virtualization, data can be provided to the active users who are at high need to utilize the resources provided within the cloud. As this data (or service is stored (or offered outside the data owner's boundaries, they are skeptical for utilizing cloud technology in order to store or utilize their data or service. There are many issues for these active clients (companies or individuals to be petrified at the thought of using cloud computing paradigm. Some of the main issues that make the clients not to choose cloud computing may be determined because of three important security aspects such as confidentiality, integrity, and availability. This research focused on the security models that relate confidentiality issues. A literature Review is performed for analyzing the existing confidentiality frameworks and security models in the area of grid computing, cluster computing and virtualization. A new theoretical framework is then designed to overcome confidentiality issues thereby improving the client‟sgeneric understanding of cloud computing services. The resulting framework when implemented in real world would motivate clients to transform their businesses on to cloud.

    Dens invaginatus is an anomaly characterized by an infolding of enamel and dentin that can lead to caries and pulpal death while the tooth is still immature, and present difficulties with diagnosis and treatment. Generally such open apices are managed by long term apexifaction procedures. This article demonstrated rapid management of a maxillary lateral incisor having a type 2 dens invaginatus, necrotic pulp, open apex and very large periradicular lesion using calcium hydroxide for one week prior to placement of a mineral trioxide aggregate (MTA) plug. After setting of the MTA, the remaining canal space was obturated using a warm vertical gutta percha technique. At 6 months follow-up the patient was asymptomatic, the lesion had almost entirely resolved, and, the root was already completely surrounded by bone.

    2017-01-01

    Background The aim of the study is to evaluate the resistance vertical root fracture (VRF) of mineral trioxide aggregate (MTA) filled-immature permanent roots by using three different vehicles. Material and Methods Forty-extracted human single-rooted mandibular premolars were selected and the root length was standardized to the length of 9 mm. For simulation of immature tooth apices, peeso reamers were introduced into the root canals and the prepared roots were assigned into three experimental groups according the used vehicle (distilled water-DW, prophylene glycol-PG, chlorhexidine-CHX) and control group (n=10). To simulate a periodontal membrane, the apical 7 mm of all roots was covered with wax to obtain a 0.2- to 0.3-mm-thick layer before embedding the roots into acrylic cylinders. A vertical force was applied (1mm/min) using a universal testing machine and the maximum load (F-max) that fracture occurred and the fracture mode (splint or comminuted) was recorded. Data were presented as mean and standard deviations. Statistical analysis was performed using Kruskal-Wallis, Mann-Whitney U Test was used for multiple comparisons. Results There were significant differences between fracture strength of experimental groups with that of control group (p0.05). In all groups, split fracture was the most common fracture mode. Conclusions MTA increases resistance of immature permanent teeth to VRF. Based on the results of this study, it can be concluded that mixing MTA with CHX or PG as the vehicle do not alter VRF resistance of simulated immature permanent roots.

    This in vivo study compared the effect of mineral trioxide aggregate (MTA), IRM, Super EBA and ZOE in a puttylike consistency, used as retrofilling materials, in the healing process of periapical tissue of pulpless dogs' teeth submitted to a conventional retrofilling technique. Twenty-four premolars obtained from three dogs were used. At the first intervention, the animals were anesthetized, coronal access was obtained and pulpectomy was done. Root canals were kept open to the oral environment for 180 days to induce the formation of apical lesions. After surgical removal of the lesions with curettes, 2 mm of the apical root was cut out perpendicular to the long axis of the teeth, and root-end cavities were shaped with a low-speed round bur. The bone cavities were irrigated and dried, and the root-end cavities were filled with MTA, IRM, Super EBA and ZOE in a puttylike consistency. The bone cavities were passively filled with blood and flaps were sutured. The coronal access openings were cleaned and double-sealed with ZOE and amalgam. After 180 days, the animals were killed by anesthetic overdose, maxilla and mandible were removed and the pieces were processed for histomorphologic analysis. Data were evaluated blindly on the basis of several histopathologic events and the scores obtained were analyzed statistically using the Kruskal Wallis test. No significant differences were observed among MTA, Super EBA and IRM (p>0.05). However, ZOE had a significantly more negative influence on the apical healing (pIRM had similar histopathologic effects among each other and better performance than ZOE used in a puttylike consistency. Furthermore, only MTA stimulated hard tissue deposition in direct contact with the retrofilling material, even when it was inserted under critical conditions.

    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.

    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...

    Introduction. The etiology of exposure determines pulpal response, making it crucial to distinguish between mechanical and carious exposure. This study clinically and radiographically evaluated the success of MTA pulpotomies conducted to treat carious and mechanical pulp exposure. Materials and Methods. This study was conducted with 50 mandibular primary molar teeth. Teeth were divided into 2 groups according to status of the exposure site, with teeth surrounded by carious dentin placed in a carious exposure group and those surrounded by sound dentin in a mechanical exposure group. MTA pulpotomies were performed for both groups. Treatment was followed up clinically and radiographically for 18 months. Results. Clinical and radiographic success rates at 18 months were 100% for both groups. Success rates did not vary significantly between the groups (p = 1.000). Pulp canal obliteration was only seen in the carious exposure group, observed in 2 teeth (8.3%). Conclusion. The long term success rates achieved in this study indicate that MTA can be used as a vital pulpotomy material for the long term success in primary teeth with either mechanical or carious exposure. The findings of the present study highlight the fact that treatment prognosis is dependent upon diagnosis and selection of the appropriate materials for treatment. PMID:27995139

Objective: The aim of this study was to evaluate chromatic alterations in human tooth crowns induced by a Mineral Trioxide Aggregate-based sealer (MTA Fillapex® and a commonly used ZnOE-based sealer (Roth-811. The tested null hypothesis was that the application of the materials did not induce clinically perceptible crown discoloration (Ho: CIE color difference ΔE<3.7. Material and Methods: Forty five fully developed, intact, mandibular third molars were sectioned 1 mm below the cemento-enamel junction. The pulp chambers were chemomechanically debrided via the cervical access. The specimens were randomly assigned into three groups Group 1: MTA Fillapex, Group 2: Roth 811, Group 3: Negative control (unfilled and immersed in individually marked vials containing distilled water up to the cervix (37±1°C. The spectral reflectance lines were recorded by utilizing a UV-VIS spectrophotometer equipped with integration sphere in the visual spectrum at baseline, 1 week, 1 and 3 months after material placement. Data were transformed into values of the CIE L*a*b* color system and the corresponding ΔE values were calculated. Statistical analysis was performed using two-way mixed ANOVA models, at p=0.05 level of significance. Results: A statistically significant increase in a* and b* chromatic parameters of the MTA Fillapex Group was measured. However, ΔE values did not exceed the human eye perceptibility threshold (set at ΔE<3.7 during the experimental period (ΔEt3=2.88. In Roth-811 Group, a statistically significant decrease in L* and a statistically significant increase in a* and b* chromatic parameters was measured, during all observation periods. Resultant ΔE values exceeded the human eye perceptibility threshold after 1 week (ΔEt1=5.65.

    Full Text Available Introduction. One of the problems encounted in endodontic treatment is the treatment of vital open apex teeth. Among different materials used for this purpose, Calcium hydroxide is the most widly used material. The purpose of this study was to compare a newly introduced material called MTA (Mineral Trioxide Aggregate with calcium hydroxide in apexogenesis procedure. Methods: Fourty open apex canine teeth of 10 young cats were used in this study. Crowns of the teeth were resected and access cavities were slightly extended. Floor of pulp chamber of 16 teeth were packed with MTA and that of the other 16 teeth with Ca(OH2.Access cavities were double sealed using ZOE and Amalgam. After 4-6 months the animals were sacrificed and the pulp and periodical tissues were examined by histologic evaluation. Four intact teeth were also used as negative control and 4 teeth without coronal seal were used as positive control. Results. Radiographic evaluation of MTA treated teeth after six months indicated that the apex of all of the teeth were closed and no calcified bridge was observed. In contrast, the apex of 13 out of 16 teeth treated with Ca(OH2 had been closed and in calcium hydroxide samples calcified bridge had been formed. Histologically, there was a significant difference in microscopic changes of the pulp between the two treatment groups (P<0.05. The pulp of the teeth with MTA was similar to that of a normal teeth and they showed no calcified bridge. Furthermore, histologic investigation of the periapical area showed no statistically significant difference between the two groups. Discussion: Based on the results obtained in this study and the previous findings despite the fact that Ca(OH2 may result in the apical closure because MTA causes less pulpal changes in apexogenesis need MTA treated teeth may not further root canal therapy. Therefore, MTA application is superior to Ca(OH2 for apexogenesis procedures.

    Direct pulp capping is one of the most common dental practices in endodontic therapy. This systematic review and meta-analysis aim to determine whether the effect of mineral trioxide aggregate (MTA) and calcium hydroxide for direct pulp capping is different, as measured by the clinical and radiographic analysis. The study list was obtained by searching PubMed, Springer Link, Scopus and Cochrane Database. Only those papers that met the inclusion criteria were analyzed. The results indicated that four studies met the inclusion criteria. Statistically significant difference was found between the success rates of MTA and calcium hydroxide treated teeth that needed direct pulp capping (P=0.002). Clinical assessments of the MTA versus calcium hydroxide for direct pulp capping suggested that MTA was superior to calcium hydroxide in direct pulp capping resulting in a lower failure rate (risk difference 0.1 [95% CI 0.04 to 0.16]). In conclusion, MTA has a higher clinical success rate for direct pulp capping comparing to calcium hydroxide, and might be a suitable replacement for calcium hydroxide.

    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

    Risultati e conclusioni: A causa di alcuni problemi di salute, la bambina è tornata dopo 6 mesi. È stata osservata la formazione di tessuto duro e il controllo rx mostrava una chiara evidenza di formazione radicolare. Abbiamo eseguito il restauro finale di 36 con materiali compositi. Al controllo dopo 6 mesi e 7 anni non risultano segni clinici e radiografici di patologia pulpare o radicolare. In conclusione, l’MTA sembra essere un materiale utilizzabile con successo per il mantenimento della vitalità pulpare. Inoltre offre un’ottima impermeabilità, anche nei casi in cui ha avuto luogo una perdita di integrità del materiale di otturazione provvisorio.

    Full Text Available Background and Aim: Achieving appropriate seal in canal obturation is the main goal of endodontic therapy. However, in some cases, it can not be obtained by non-surgical procedures alone. Retrograde surgery is one of the most common procedures in endodontics. Apical seal improvement can be obtained by root end filling and decreasing the root end resection angle (bevel angle. The aim of this study was to investigate the role of bevel angle on apical microleakage following the use of amalgam and MTA as root end filling materials. Materials and Methods: In this experimental study, 128 extracted human teeth were instrumented and obturated by lateral condensation technique. The teeth were divided into two groups and the apical root resection was performed by high speed fissure bur (one group perpendicular to the long axis of the teeth and the other 45 to the long axis. The 3 mm root end cavity was prepared by ultrasonic device. Each group was divided into two subgroups: One filled with amalgam and the other with MTA. Teeth were incubated for 72 h, covered by two layers of nail polish (except for apical 3mm and submerged in methylene blue for 48 h. Teeth were washed under tap water and mesiodistally dissected by low speed disc. Dye penetration was evaluated by stereomicroscope. Data were analysed by two way ANOVA and Tukey tests with p<0.05 as the limit of significance. Results: The results showed that retrofill material type had a significant effect on microleakage and MTA was superior to amalgam in this respect. Bevel angle failed to show any significant effect on apical microleakage. Conclusion: Based on the results of this study, it seems that the use of MTA instead of amalgam in clinical practice can improve the success rate of endodontic surgery whereas the bevel angle can be determined based on the status of each individual case; However, increasing the bevel angle seems to increase microleakage due to exposure of more dentinal tubules.

    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.

    Laser irradiation has been investigated in terms of preventing leakage in retrofilled root canals. The aim of the present study was to evaluate the effect of neodymium-doped yttrium aluminum garnet (Nd: YAG) laser on the bacterial leakage of mineral trioxide aggregate (MTA)-retrofilled roots. In this ex vivo experimental study, 90 single-rooted incisor teeth were filled with gutta-percha and AH26 sealer. The apical 3 mm of all the roots were resected and 3-mm retrocavities were prepared by an ultrasonic device. The specimens were randomly divided into two experimental (n = 25), one positive control (n = 10), and two negative control (n = 10) groups. In the laser + MTA group, the cavity walls were irradiated by Nd: YAG laser prior to MTA placement. In the MTA group, MTA was placed without laser irradiation. The root surfaces were covered with two layers of nail varnish except for the apical 2 mm. The specimens were then embedded in a bacterial leakage test system and examined daily for 90 days. Contamination periods were recorded. Data were analyzed by Kaplan-Meier and Mann-Whitney U tests (α = 0.05). Five teeth with and five teeth without laser irradiation underwent scanning electron microscopic evaluation. The specimens in the laser + MTA group were contaminated earlier than those in the MTA group (p MTA in comparison to the apical seal achieved by MTA without laser irradiation. Further studies are recommended to provide a better seal for the MTA-retrofilled teeth after laser irradiation.

    The manner in which healthcare and medical professionals serve their athlete patients is governed by a variety of relevant codes of conduct. A range of codified rules is presented that refer both the welfare of the patient and the maintaining of confidentiality, which is at the heart of trustworthy relations. The 2009 version of the World Anti-Doping Code (WADC), however, appears to oblige all healthcare professionals not to assist athletes if they are known to be engaged in doping behaviours under fear of removal from working with athletes from the respective sports. In contrast, serving the best interests of their athlete patients may oblige healthcare professionals to give advice and guidance, not least in terms of harm minimisation. In so far as the professional conduct of a healthcare professional is guided both by professional code and World Anti-Doping Code, they are obliged to fall foul of one or the other. We call for urgent and pressing inter-professional dialogue with the World Anti-Doping Agency to clarify this situation.

    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

    The four solid rocket booster (SRB) hold-down posts are fastened to the mobile launch platform (MLP) with four large nuts. At liftoff the nuts are split with explosive changes to release the SRB/Shuttle. A blast container is placed over the nuts to protect the vehicle from flying debris. The blast container is a reusable part and has to be protected from aerodynamic heating during flight. The thermal protection system (TPS) used to protect these blast containers is cork. Fitting the flat cork sheet to this hemispherical shaped blast container is both time consuming and expensive. Another problem is removing the charred cork and epoxy glue from the blast containers. Replacements of this cork with another TPS material such as MTA-2 was examined. Heating rates along the centerline of the forward facing areas of the blast container were determined. The feasibility of using 1/2 in. MTA-2 on the SRB blast containers for protection from ascent, plume impingement and reentry heating is demonstrated.

    The nucleosome remodeling and deacetylase (NuRD) complex is a widely conserved transcriptional co-regulator that harbors both nucleosome remodeling and histone deacetylase activities. It plays a critical role in the early stages of ES cell differentiation and the reprogramming of somatic to induced pluripotent stem cells. Abnormalities in several NuRD proteins are associated with cancer and aging. We have investigated the architecture of NuRD by determining the structure of a subcomplex comprising RbAp48 and MTA1. Surprisingly, RbAp48 recognizes MTA1 using the same site that it uses to bind histone H4, showing that assembly into NuRD modulates RbAp46/48 interactions with histones. Taken together with other results, our data show that the MTA proteins act as scaffolds for NuRD complex assembly. We further show that the RbAp48-MTA1 interaction is essential for the in vivo integration of RbAp46/48 into the NuRD complex.

    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.

    2008-05-01

    Confidentiality is the secret-keeping duty that arises from the establishment of the professional relationship psychologists develop with their clients. It is a duty created by the professional relationship, it is set forth in the American Psychological Association's (2002) Ethical Principles and Code of Conduct, and it is codified in many state regulations. However, the difference between confidentiality and legal privilege; how, why, and when it can be violated; and the reasons for so doing are not well understood by many practitioners. While on the surface confidentiality might seem to be an easy concept to apply to professional practice, in fact it is quite complex and filled with exceptions that frequently differ from circumstance to circumstance and from state to state. A lack of respect for and a lack of familiarity with the significance of these exceptions could have dire professional consequences. This article reviews the ethical imperative of confidentiality and then provides examples of legal cases that help to better understand its complexity. Then, we offer strategies designed to help metal health practitioners when they are confronted with questions regarding confidentiality and privilege.

    2012-01-01

    In coding schemes for the wire-tap channel or the broadcast channels with confidential messages, it is well known that the sender needs to use a stochastic encoding to avoid the information about the transmitted confidential message to be leaked to an eavesdropper. In this paper, it is investigated that the trade-off between the rate of the random number to realize the stochastic encoding and the rates of the common, private, and confidential messages. For the direct theorem, the superposition coding scheme for the wire-tap channel recently proposed by Chia and El Gamal is employed, and its strong security is proved. The matching converse theorem is also established. Our result clarifies that a combination of the ordinary stochastic encoding and the channel prefixing by the channel simulation is suboptimal.

    Therapeutic of apexification with calcium hydroxide has been extensively used in clinical practice, but this technique has some drawbacks (long duration of treatment, weakening of the radicular walls). Different studies have proposed to close the apex opened with MTA (Mineral trioxide Aggregate) which is biocompatible, bacteriostatic, this material induces regeneration of the periapical region through the formation of cementum, bone and periodontal ligament (1, 2). This case report describes the technique of setting up in a single step of the Mineral trioxide Aggregate as an apical barrier for immature permanent roots. This method has allowed us an immediate apical sealing and a root canal filling and a coronary restore permanently as soon as possible. The radiological control confirmed that this type of apexification could be successful with periapical regeneration ad-integrum.

    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.

    2008-02-01

    Full Text Available This study evaluated the sealing ability of apical plugs fabricated with gray MTA AngelusTM 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 AngelusTM, CPM TM 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.

    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%.

  9. 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.

    Gelpi, R J; Pérez, M L; Rancich, A M; Mainetti, J A

    2000-01-01

    Confidentiality, together with the ethical principles of beneficence and non-maleficence, is the most important rule in Medical Oaths at the present time. However, the scientific-technical advances in medicine have made this rule one of the most controversial ones because of its exceptions. In consequence, the aim of the present paper is to comparatively analyze the rule of confidentiality in Medical Oaths of different places, times, origins and in different versions of the Hippocratic Oath in order to determine what should be kept a secret and with what degree of commitment (absolute or "prima facie"). Of the thirty six analyzed Oaths, twenty-seven manifest this rule and nine do not. No relation was found between the manifestation of this rule and the place, time, origin and different versions of the Hippocratic Oath. Most pledges suggest not to reveal what has been seen or heard during the medical act, the same as in the Hippocratic Oath. Seven texts point out that confidentiality should be absolute and four give exceptions in connection with beneficence and justice principles and the moral duty of causing no damage to third parties. Two pledges specify protection of privacy. In conclusion, today confidentiality is considered to be a moral duty for the benefit of the patient and out of consideration for his autonomy; however, at the present time in medicine the duty of keeping absolute secrecy is being reconsidered.

    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.

  19. Data security and patient confidentiality: the manager's role.

    Science.gov (United States)

    Fisher, F; Madge, B

    1996-10-01

    The maintenance of patient confidentiality is of utmost importance in the doctor patient relationship. With the advent of networks such as the National Health Service Wide Area Network in the UK, the potential to transmit identifiable clinical data will become greater. Links between general practitioners (GPs) and hospitals will allow the rapid transmission of data which if intercepted could be potentially embarrassing to the patient concerned. In 1994 the British Medical Association launched a draft bill on privacy and confidentiality and in association with this bill it is pushing for encryption of all clinical data across electronic networks. The manager's role within an acute hospital, community units and general practice, is to ensure that all employees are aware of the principles of data protection, security of hospital computer systems and that no obvious breaches of security can occur at publicly accessible terminals. Managers must be kept up to date with the latest developments in computer security such as digital signatures and be prepared to instigate these developments where practically possible. Managers must also take responsibility for the monitoring of access to terminals and be prepared to deal severely with staff who breach the code of confidentiality. Each manager must be kept informed of employees status with regard to their 'need to know' clearance level and also to promote confidentiality of patient details throughout the hospital. All of the management team must be prepared to train new staff in the principles of data security as they join the organisation and recognise their accountability if the programme fails. Data security and patient confidentiality is a broad responsibility in any healthcare organisation, with the Chief Executive accountable. In family practice, the partners are responsible and accountable. The British Medical Association believes as a matter of policy, that allowing access to personal health data without the patients

    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.

    Service level agreements provide clearer descriptions of the services to be provided and the objectives to be met. In many instances it is the first time that services have been defined allowing their performance to be suitably measured. They should be output based and not too prescriptive on how the services are to be delivered. The emphasis should be on establishing outputs and the arrangements for monitoring achievement. Customer expectations can exceed available resources and arbitration may become necessary if agreement cannot be reached on internal service level agreements. The main requirements of customers for change through service level agreements is usually improved communications on job status that includes notification of any delays and that agreed response times will be met.

  9. A Comparative Study of Apical Healing of Open Apices Using MTA and Ca(OH2 Apical Plugs in Cats

    M. H. Zarrabi

    2005-06-01

    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

    1999-01-01

    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.

    1983-08-01

    The problem of the impact of confidentiality on health effectiveness is discussed along five points: (1) Communication facilities between health departments are main features of health information systems. (2) Efforts, costs, limits of data protection. The privacy violation risks have to be related to the data protection costs. (3) Paradox of the fundamental rights to confidentiality regarding privacy of the individual and the preponderant interest of the State. (4) Facing the increasing health costs, the need for medical and hospital control systems is assessed. (5) New benefits in medicine and in the quality of care are partly the results of more or less extensive studies in epidemiology at national levels. The general conclusion is concerned with the risks that the computer could become an instrumental substitute for human reason with the progressive drop out of responsibility of health officers.

  12. On the Compound MIMO Broadcast Channels with Confidential Messages

    CERN Document Server

    Kobayashi, Mari; Shamai, Shlomo; Debbah, Merouane

    2009-01-01

    We study the compound multi-input multi-output (MIMO) broadcast channel with confidential messages (BCC), where one transmitter sends a common message to two receivers and two confidential messages respectively to each receiver. The channel state may take one of a finite set of states, and the transmitter knows the state set but does not know the realization of the state. We study achievable rates with perfect secrecy in the high SNR regime by characterizing an achievable secrecy degree of freedom (s.d.o.f.) region for two models, the Gaussian MIMO-BCC and the ergodic fading multi-input single-output (MISO)-BCC without a common message. We show that by exploiting an additional temporal dimension due to state variation in the ergodic fading model, the achievable s.d.o.f. region can be significantly improved compared to the Gaussian model with a constant state, although at the price of a larger delay.

    Children suffer most from today's increasing precariousness. In France, access to care is available for all children through various structures and existing measures. The support for foreign children is overseen by specific legislation often unfamiliar to caregivers. Pediatric emergencies, their location, organization, actors, and patient flow are a particular environment that is not always suitable to communication and may lead to situations of abuse. Communication should not be forgotten because of the urgency of the situation. The place of the child in the dialogue is often forgotten. Considering the triangular relationship, listening to the child and involving the parents in care are the basis for a good therapeutic alliance. Privacy and medical confidentiality in pediatric emergencies are governed by law. However, changes in treatments and medical practices along with the variety of actors involved imply both individual and collective limitations, to the detriment of medical confidentiality.

    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).

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

    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.

    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.

    Full Text Available The aim of this study is to provide suitable security to data based on the security needs of data. It is very difficult to decide (in cloud which data need what security and which data do not need security. However it will be easy to decide the security level for data after data classification according to their security level based on the characteristics of the data. In this study, we have proposed a data classification cloud model to solve data confidentiality issue in cloud computing environment. The data are classified into two major classes: sensitive and non-sensitive. The K-Nearest Neighbour (K-NN classifier is used for data classification and the Rivest, Shamir and Adelman (RSA algorithm is used to encrypt sensitive data. After implementing the proposed model, it is found that the confidentiality level of data is increased and this model is proved to be more cost and memory friendly for the users as well as for the cloud services providers. The data storage service is one of the cloud services where data servers are virtualized of all users. In a cloud server, the data are stored in two ways. First encrypt the received data and store on cloud servers. Second store data on the cloud servers without encryption. Both of these data storage methods can face data confidentiality issue, because the data have different values and characteristics that must be identified before sending to cloud severs.

    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.

    2012-01-01

    We propose a new segmentation evaluation metric, called segmentation similarity (S), that quantifies the similarity between two segmentations as the proportion of boundaries that are not transformed when comparing them using edit distance, essentially using edit distance as a penalty function and scaling penalties by segmentation size. We propose several adapted inter-annotator agreement coefficients which use S that are suitable for segmentation. We show that S is configurable enough to suit a wide variety of segmentation evaluations, and is an improvement upon the state of the art. We also propose using inter-annotator agreement coefficients to evaluate automatic segmenters in terms of human performance.

    Full Text Available Statement of Problem: Pulpotomy is the most common pulp treatment of primary molars. Formocresol pulpotomy has enjoyed long-term clinical use and success, but concerns over its toxicity and mutagenicity have prompted research into other pulpotomy techniques.Purpose: The aim of the present study was to compare the relative success of formocresol, ferric sulfate and MTA pulpotomy methods in primary molars, using clinical and radiographic examinations.Materials and Methods: 135 second primary molars requiring pulpotomy treatment were selected from children between 3 and 6 years of age. They were randomly assigned to three groups according to the pulpal therapy technique: pulpotomy with formocresol, ferric sulfate, and MTA. All pulpotomized teeth were restored with amalgam. The subjects selected for clinical and radiographic evaluations were monitored periodically for 3 and 12 months.Results: The clinical success rate of the MTA group was 82.1% after one year which was significantly less than the 100% observed in the other groups (P= 0.005.The highest and lowest radiographic success rates after one year, were encountered in the formocresol (92.5% and MTA (69.2% groups respectively, which showed a significant difference (P=0.01. The success rate of the ferric sulfate group was 80.50%.Conclusion: MTA is not recommended as a pulpotomy medicament in primary teeth,but ferric sulfate may be acceptable as an alternative to formocresol.

    Objective. To understanding the molecular mechanisms in invasion and metastasis of the ovarian car-cinoma, we investigate a novel candidate metastasis-associated gene (MTA1) and nm23H1 mRNA ex-pression and mutation in ovarian carcinoma.Methods. Twenty primary ovarian carcinoma specimens, 20 corresponding lymph nodes and 8 normalovarian was examined for mRNA expression and mutation of MTA1 and nm23H1 genes by revere-tran-scription ploymerase chain reaction(RT-PCR) and RT-PCR-SSCP analysis. The level of the expressionwas determined by the relative optic desity (ROD) of the PCR products.Results. The frequency of MAT1 overexpression was 100%(7/7) in primary ovarian carcinoma withmetastasis but only 38.5% (5/13) in those without metastasis (P=0.0103 ). Overexpression of MAT1 wasobserved in 87.5%(6/7) of lymph nodes with metastasis but only 23%(3/13) of lymph nodes withoutmetastasis (P=0.0118). In contrast with MAT1, low expression of nm23H1 mRNA was seen in 7 of 7 o-varian carcinoma with metastasis but only in 4 of 13(30%) of those without metastassis (P=0.0043). Lownm23H1 expression was also seen in 7 of 7 lymph nodes with metastasis but only in 5 of 13 (38.5%)nonmetastatic lymph nodes (P=0.0102). The ROD ratio of MAT1 to nm23H1 increased with the develop-ment of metastasis. No mutation of MAT1 and nm23H1 genes was found by SSCP analysis.Conclusion. The mRNA expression of MTA1 and nm23H1 is positively and negatively correlated withlymph node metastasis, respectively. Expression abnormalities but not mutation of the two genes are fre-quent events related to lymph node metastasis of ovarian cancer.

    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

    Full Text Available Certificates of Confidentiality, issued by agencies of the U.S. government, are regarded as an important tool for meeting ethical and legal obligations to safeguard research participants' privacy and confidentiality. By shielding against forced disclosure of identifying data, Certificates are intended to facilitate research on sensitive topics critical to the public's health. Although Certificates are potentially applicable to an extensive array of research, their full legal effect is unclear, and little is known about stakeholders' views of the protections they provide. To begin addressing this challenge, we conducted a national survey of institutional review board (IRB chairs, followed by telephone interviews with selected chairs, to learn more about their familiarity with and opinions about Certificates; their institutions' use of Certificates; policies and practices concerning when Certificates are required or recommended; and the role Certificates play in assessments of research risk. Overall, our results suggest uncertainty about Certificates among IRB chairs. On most objective knowledge questions, most respondents chose the incorrect answer or 'unsure'. Among chairs who reported more familiarity with Certificates, composite opinion scores calculated based on five survey questions were evenly distributed among positive, neutral/middle, and negative views. Further, respondents expressed a variety of ideas about the appropriate use of Certificates, what they are intended to protect, and their effect on research risk. Nevertheless, chairs who participated in our study commonly viewed Certificates as a potentially valuable tool, frequently describing them as an 'extra layer' of protection. These findings lead to several practical observations concerning the need for more stakeholder education about Certificates, consideration of Certificates for a broader range of studies, the importance of remaining vigilant and using all tools available to

    Several members of the Royal Canadian Mounted Police testified at hearings conducted by a commission appointed to study the confidentiality of health records. On approximately 300 occasions, the police had obtained medical information from physicians and hospitals in Ontario without the prior consent of the patient. The court established that the identity of persons who had furnished the information was privileged information for physicians and other persons subject to the control of a hospital board, but not for various employees of the hospital who were not subject to professional standards of discipline.

    This work carried out a histological analysis on bone defects grafted (MTA) treated or not with LED, BMPs, and membrane (GBR). Benefits of their isolated or combined usage on bone repair were reported, but not their association. Ninety rats were divided into ten groups and each subdivided into three. Defects on G II and I were filled with the blood clot. G II was further LED irradiated. G III and IV were filled with MTA; G IV was further LED irradiated. In G V and VI, the defects were filled with MTA and covered with a membrane (GBR). G VI was further LED irradiated. In G VII and VIII, BMPs were added to the MTA and group VIII was further LED irradiated. In G IX and X, the MTA + BMP graft was covered with a membrane (GBR). G X was further LED 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 use of LED light alone dramatically reduced inflammation. However, its use on MTA associated with BMP and/or GBR increased the severity of the inflammatory reaction. Regarding bone reabsorption, the poorest result was seen when the LED light was associated with the MTA + BMP graft. In the groups Clot and MTA + GBR, no bone reabsorption was detectable. Increased collagen deposition was observed when the LED light was associated with the use of the MTA associated with BMP and/or GBR. Increased new bone formation was observed when the LED light was used alone or associated with the use of MTA + GBR, MTA + BMP, on association of MTA + BMP + GBR and when BMP was added to the MTA. Our results indicate that the use of LED light alone or in association with MTA, MTA + BMP, MTA + GBR, and MTA + BMP + GBR caused less inflammation, and an increase of both collagen deposition and bone deposition as seen on both histological and morphometric analysis.

  11. Genetic secrets: Protecting privacy and confidentiality in the genetic era. Final report

    Energy Technology Data Exchange (ETDEWEB)

    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.

    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.

    German is a complicated language. Any speaker of e.g. French or Danish who has ever tried to learn German would agree to this. Coming from languages with only two genders and with no case outside the pronoun system, German, with three genders and with four cases throughout the nominal system, seems...... unjustifiably complicated, as if it had been specially designed to torment poor students. However, there is one area where German agreement morphology could not possibly be simpler, and where German is much easier for non-native speakers than e.g. French or Danish: predicative adjectives. Both gender and number...... distinctions, disappear when adjectives are used predicatively. This paper will try to account for why the Germanic languages that inflect attiributive adjectives but not predicative ones are all SOV-languages (e.g. German, Dutch, Frisian and Yiddish)....

    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.

    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

    Background It is necessary apical plug material to exhibit proper adaptation with the root canal walls. Presence of voids at the interface between the root canal wall and this material result in micro leakage, which might have a relationship with post treatment disease. The aim of the present study was to evaluate the effect of different mixing (manual and ultrasonic) and placement (manual and manual in association with indirect ultrasonic) method of Mineral Trioxide Aggregate (MTA) on the void count and dimension in the apical plug in natural teeth with simulated open apices. Material and Methods Eighty human maxillary central incisors were selected. After simulation of the open apex model, the teeth were assigned to 4 groups based on the mixing and placement techniques of MTA: group 1, manual mixing and manual placement; group 2, manual mixing and manual placement in association with indirect ultrasonic; group 3, ultrasonic mixing and and manual placement; and group 4, ultrasonic mixing and manual placement in association with indirect ultrasonic. The prepared samples were placed within gypsum sockets in which the periodontal ligament was reconstructed with polyether impression material. In group 1, after mixing, the material was condensed with a hand plugger. In group 2, after mixing, the ultrasonic tip was contacted with the hand plugger for 2 seconds. In groups 3 and 4, mixing was carried out with the ultrasonic tip for 5 seconds and in groups 3 and 4, similar to groups 1 and 2, respectively, the materials were placed as apical plugs, measuring 3 mm in length. A wet cotton pellet was placed at canal orifices and dressed with Cavit. After one week, the cone beam computed tomography (CBCT) technique was used to count the number of voids between the material and root canal walls. The void dimensions were determined using the following scoring system: score 1, absence of voids; score 2, the void size less than half of the dimensions of the evaluated cross

    Full Text Available Aim: The aim of the study was to compare the conventional ThermaFil obturation technique and ThermaFil obturation with mineral trioxide aggregate (MTA as an apical barrier, with regard to apical sealing and extrusion. Materials and Methods: Twenty extracted human canines were instrumented using a crown-down technique and divided into two groups. The experimental group was obturated using ThermaFil obturation with MTA as an apical barrier and the control group was obturated using the conventional ThermaFil obturation technique. AH Plus sealer was used in both the groups. Apical extrusion was recorded. Teeth of both the groups were coated with nail polish, except for the apical 3 mm. After 24 h, they were suspended in black India ink for 48 h. Canines were decalcified, rendered transparent, and linear dye penetration was measured under ×40 stereomicroscope. Results: There was a significant extrusion noticed in conventional ThermaFil obturation technique. Frequency of extrusion of sealer and/or gutta-percha was supposed to be evaluated using χ² test, but since the values of the samples of ThermaFil plus MTA group were zero, statistical analysis could not be conducted, whereas linear dye leakage was calculated with Mann-Whitney U test because the distribution was abnormal. Conclusion: Although ThermaFil plus MTA group showed microleakage, extrusion of sealer and the core material was prevented in comparison with conventional ThermaFil obturation technique. It is advantageous to use MTA as an apical plug as there is no fear of apical extrusion and the root canal system can then be packed three dimensionally against this barrier using any thermoplasticized gutta-percha obturation technique.

  1. 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...

    2013-02-01

    While it is acknowledged that there is a need for more qualitative research on suicide, it is also clear that the ethics of undertaking such research need to be addressed. This article uses the case study of the authors' experience of gaining ethics approval for a research project that asks people what it is like to feel suicidal to (a) analyse the limits of confidentiality and anonymity and (b) consider the ways in which the process of ethics review can shape and constrain suicide research. This leads to a discussion of the ways in which ethics committees assess and monitor qualitative research more generally and some preliminary suggestions for how this might be improved.

    2003-01-01

    The RMC technology developed by RIPP has been applied in a 1.5 Mt/a medium pressure hydrocracking unit at Shanghai Petrochemical Company. The unit was successfully put on stream in September 2002. Calibration of the performance of the commercial unit has shown that the RMC technology has higher hydrogenation activity and selectivity, and high quality product can be obtained under lower reaction temperature. The heavy naphtha with less than 0.5 ppm of sulfur and 58.5 m% potential aromatic content is a good feedstock for catalytic reforming unit. The diesel with less than 0.5 ppm of sulfur, 6.6 m% aromatics and cetane rating of 56 is a high-grade diesel fuel. The hydrocracked tail oil containing more than 14 m% hydrogen and mere 1.7m% aromatics could be used as a good feedstock for steam cracking process to produce ethylene.

    Background. Maximum sealing ability or adhesion of endodontic sealers can be achieved after effective removal of the smear layer. Endodontic irrigants assist in adequate removal of the smear layer, improving the retention mechanism. The aim of this study was to evaluate the effect of two different root canal irrigation solutions (5.25% NaOCl followed by 17% EDTA and QMix) on the apical sealing ability of two different root canal sealers (MTA Fillapex and Adseal). Methods. Forty-six single-canal teeth were divided into 4 experimental groups of 10 teeth each and a positive and negative group of 3 teeth each. The root canals were prepared using step-back technique. The teeth in groups 1 and 2 were irrigated with 5.25% NaOCl followed by 17% EDTA and the teeth in groups 3 and 4 were irrigated with QMix. Finally all the teeth were flushed with sterile saline and dried using paper points. Obturation was accomplished by gutta-percha using lateral condensation technique. MTA Fillapex sealer was used in groups 1 and 3 whereas Adseal was used in groups 2 and 4. Dye penetration method was used to evaluate apical leakage. Data were analyzed with Kruskal-Wallis and Mann-Whitney U tests using SPSS 14. Statistical significance was set at P < 0.05. Results. Group 3 showed maximum amount of apical leakage (3.7±0.3 mm) whereas group 2 exhibited the least amount of apical leakage (2.1 ± 0.4 mm) among all the experimental groups. Significant differences were found in the amount of apical leakage between all the groups (P = 0.00001). Conclusion. Within the limitations of this study, 5.25% sodium hypochlorite followed by 17% EDTA and Adseal resulted in the best apical seal. PMID:28096952

  6. 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.

    2016-03-01

    Achieving a balance between giving access to information and respecting donors' confidentiality is a crucial issue for any biobank, with its large number of samples and associated information. Despite the existence of much empirical literature on confidentiality, there are too few surveys in the Middle East about the topic, particularly in the Saudi context. A survey was conducted of 200 respondents at King Abdulaziz Medical City in Riyadh, Saudi Arabia, among 5 groups of equal size, comprised of researchers, physicians, medical students, donors and laypersons, respectively. The majority of participants agreed that confidentiality is an important issue and that it is well protected in the Saudi biobank. All 5 groups showed different attitudes toward disclosing information to various third parties. They were in favor of allowing treating physicians, and to a certain extent family members, to have access to medical and genetic results from research. No significant differences were found between views on medical and genetic confidentiality. The majority of respondents agreed that confidentiality might be breached in cases with specific justified reasons. Even considering differences in religion, culture and other factors, the results of the study were consistent with those reported in the literature and research conducted in other countries. We therefore place emphasis on the importance of protecting and promoting patient/donor confidentiality and privacy.

  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.

    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).

  2. Security, privacy, and confidentiality issues on the Internet.

    Science.gov (United States)

    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.

  6. Notes on Agreement in Itelmen

    Directory of Open Access Journals (Sweden)

    Jonathan David Bobaljik

    2002-01-01

    Full Text Available Agreement in Itelmen is represented by means of both prefixes and suffixes. While the prefixes reference subjects (of both transitive and intransitive verbs, the suffixal agreement morphemes on a given verb may reference the subject, the object, or an oblique argument, or some combination of these. We propose that the proper characterization of the factors that determine which arguments control suffixal agreement involves a division of labour between morphology and a notion of discourse prominence/salience. In essence, we propose that the suffixal agreement morpheme is an object agreement marker, but the features of the subject are reflected in this position when the object lacks the relevant features (for example, we treat third person as the lack of a person feature, or is absent altogether (thus, intransitive verbs agree twice with their subjects. When a verb occurs with an oblique as well as a direct object, discourse salience will determine which of these non-subject arguments will control object agreement. In addition to providing a description of a complex range of facts from Itelmen, the paper sheds light on the nature of “multiple exponence” and the role of “competition” among affixes for a particular position in the verbal agreement system.

    2011-01-01

    Recent large-scale personal data loss incidents highlighted the need for public bodies to more securely handle confidential data. We surveyed trainees from all specialties in the Welsh Deanery for their knowledge and practice. All registered trainees were invited to participate in an online anonymised survey. There were 880 completed and non-duplicated responses (52.9% response rate). Responses were analysed using Microsoft Access. Over 40% (388/880 (44.1%)) did not use formal guidelines on storage or disposal of confidential data. The majority appeared to dispose of confidential paper documents securely, that is, using shredders and white shredder bags. However, there were significant numbers of unmarked responses. Clinical documents, such as theatre lists, were taken home by 281/880 (31.9%) of trainees. The majority secured their computers (569/871 (65.3%)) by either not keeping patient identifiable data on them or using encryption. However, 302/871 (34.7%) did not adequately secure their computers. The surgical and anaesthetic specialties were least aware of formal confidentiality guidelines (95/178 (53.4%)) and 52/102 (51.0%) respectively) and least secured their computers (106/178 (59.6%) and 63/102 (61.8%) respectively). Education is needed to improve knowledge and practice of confidential data handling. This may be delivered through workshops during induction programmes or as part of European Computer Driving Licence (ECDL) modules. Training is especially indicated for the surgical and anaesthetic specialties.

  9. METHODS FOR ASSESSING SECURITY THREATS CONFIDENTIAL INFORMATION FOR THE INFORMATION AND TELECOMMUNICATIONS SYSTEMS

    Directory of Open Access Journals (Sweden)

    E. V. Belokurova

    2015-01-01

    Full Text Available The article discusses the different approaches to assessing the safety of confidential information-term for information and telecommunication systems of various pre-appreciable destination in the presence of internal and external threats to its integrity and availability. The difficulty of ensuring the security of confidential information from exposure to information and telecommunication systems of external and internal threats at the present time, is of particular relevance. This problem is confirmed by the analysis of available statistical information on the impact of threats on the security circulating in the information and telecommunications system. Leak confidential information, intellectual property, information, know-how is the result of significant material and moral damage caused to the owner of the restricted information. The paper presents the structure of the indicators and criteria shows that the most promising are analytical criteria. However, their use to assess the level of security of confidential information is difficult due to the lack of appropriate mathematical models. The complexity of the problem is that existing traditional mathematical models are not always appropriate for the stated objectives. Therefore, it is necessary to develop mathematical models designed to assess the security of confidential information and its impact on information and telecommunication system threats.

  10. The end of medical confidentiality? Patients, physicians and the state in history.

    Science.gov (United States)

    Rieder, Philip; Louis-Courvoisier, Micheline; Huber, Philippe

    2016-09-01

    Medical confidentiality has come under attack in the public sphere. In recent disasters both journalists and politicians have questioned medical confidentiality and claimed that in specific contexts physicians should be compelled to communicate data on their patients' health. The murders of innocent individuals by a suicidal pilot and a Swiss convicted criminal have generated polemical debates on the topic. In this article, historical data on medical confidentiality is used to show that medical practices of secrecy were regularly attacked in the past, and that the nature of medical confidentiality evolved through time depending on physicians' values and judgements. Our demonstration is based on three moments in history. First, at the end of the 16th century, lay authorities put pressure on physicians to disclose the names of patients suffering from syphilis. Second, in the 18th century, physicians faced constant demands for information about patients' health from relatives and friends. Third, employers and insurance companies in the 20th century requested medical data on sick employees. In these three different situations, history reveals that the concept of medical confidentiality was plastic, modelled in the first instance to defend well-to-do patients, in the second instance it was adapted to accommodate the physician's social role and, finally, to defend universal values and public health. Medical secrecy was, and is today, a medical and societal norm that is shaped collectively. Any change in its definition and enforcement was and should be the result of negotiations with all social actors concerned.

    2011-03-01

    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.

  14. Application-Oriented Confidentiality and Integrity Dynamic Union Security Model Based on MLS Policy

    Science.gov (United States)

    Xue, Mingfu; Hu, Aiqun; He, Chunlong

    We propose a new security model based on MLS Policy to achieve a better security performance on confidentiality, integrity and availability. First, it realizes a combination of BLP model and Biba model through a two-dimensional independent adjustment of integrity and confidentiality. And, the subject's access range is adjusted dynamically according to the security label of related objects and the subject's access history. Second, the security level of the trusted subject is extended to writing and reading privilege range respectively, following the principle of least privilege. Third, it adjusts the objects' security levels after adding confidential information to prevent the information disclosure. Fourth, it uses application-oriented logic to protect specific applications to avoid the degradation of security levels. Thus, it can ensure certain applications operate smoothly. Lastly, examples are presented to show the effectiveness and usability of the proposed model.

  15. Why does geoprivacy matter? The scientific publication of confidential data presented on maps.

    Science.gov (United States)

    Kounadi, Ourania; Leitner, Michael

    2014-10-01

    We examined published maps containing sensitive data, and the protection methods, if any, that were used. We investigated whether the many published warnings about disclosure risk have been effective in reducing privacy risk. During an 8-year period (2005-2012), 19 journals related to GIScience, geography, spatial crime analysis, and health geography were examined. We identified 41 articles that display actual confidential information and 16 articles where confidential information is protected by the use of a geographical mask. During the investigated time frame, the numbers of articles with unmasked confidential data increased, and in total more than 68,000 home addresses were disclosed. One of the more significant findings of this study is that efforts to instill sensitivity to location privacy and disclosure risk have been relatively unsuccessful.

  16. [Confidentiality in HIV-infection/AIDS--a comment on the Communicable Disease Control Act].

    Science.gov (United States)

    Frich, J C

    1995-05-10

    The new Communicable Diseases Control Act has come into force in Norway. It makes it compulsory for a physician to warn a third party if it is obvious that a HIV-positive patient, with a high degree of certainty, puts the third party at risk of being infected with HIV. Some philosophers characterize medical confidentiality as an intransigent and absolute obligation, others as a prima facie duty. This article supports the latter view, but the author still argues that strict conditions have to be fulfilled before a physician should consider breaking medical confidentiality: The doctor must try repeatedly to gain the consent or co-operation of the patient involved. Possible negative long-term consequences for the preventive HIV-work support strict medical confidentiality.

    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.

    Full Text Available Background and Aim: Formocresol (FC has been a popular pulpotomy medicament for primary dentition in recent decades. Concerns have been raised about the toxicity and potential carcinogenicity of FC, and alternatives have been proposed. Recently, the physical and biological properties of mineral trioxide aggregate (MTA have been described in many studies. The aim of this study was to compare the success rate of pulpotomy with MTA (made in Iran and FC in primary molars."nMaterials and Methods: In this clinical trial, 30 primary molars needing pulpotomy treatment were selected and randomly divided into two groups: (15 teeth in FC and 15 in MTA group. The teeth were then pulpotomized and restored. Clinical and radiographic results were recorded at 1-3-6-9 and 12 months and success rates of two groups were compared using Fisher’s exact test with p<0.05 as the level of significance. "nResults: After 12 months, there was no statistical significant difference between MTA group (85.8% and FC group (93.3% (P 1.0. The only observed radiographic failure was internal resorption. "nConclusion: Based on the results of this study, MTA can be used as an alternative to formocresol in primary teeth pulpotomy.

    We report a new pattern of usage in current, spoken Italian that has implications for both psycholinguistic models of language production and linguistic theories of language change. In Italian, gender agreement is mandatory for both singular and plural nouns. However, when two or more nouns of different grammatical gender appear in a conjoined noun phrase (NP), masculine plural agreement is required. In this study, we combined on-line and off-line methodologies in order to assess the mechanisms involved in gender marking in the context of multiple referents. The results of two pronoun production tasks showed that plural feminine agreement was significantly more difficult than plural masculine agreement. In a separate study using offline judgements of acceptability, we found that agreement violations in Italian are tolerated more readily in the case of feminine conjoined noun phrases (e.g., la mela e la banana ‘the:fem apple:fem and the: fem banana: fem’) than masculine conjoined noun phrases (e.g., il fiore e il libro ‘the:mas flower: mas and the:mas book:mas’). Implications of these results are discussed both at the level of functional architecture within the language production system and at the level of changes in language use.* PMID:21037930

    Full Text Available The purpose was to compare the cytotoxic effects of two commonly used mineral trioxide aggregate (MTA (gray & white with the recently introduced calcium enriched mixture (CEM in L929 and Saos-2 cell lines and to determine the oxidative stressinduced by each cement. Sterile discs of each cement were submerged and incubated in complete media for 24, 48 and 72-h. The cell lines were exposed to two fold serial dilutions (1, 0.5, 0.25 X of each extract. In addition to trypan blue (TB dye exclusion test, MTT assay was carried out after 24-h. To determine the oxidative stress mediated cell toxicity, malondialdehyde (MDA concentration and total ferric reduction activity potential (FRAP were measured in the media.The MTT and TB results with 48-h and 72-h CEM extracts showed that both extracts are cytotoxic in L929 cell line at 1 X and 0.5 X dilutions, while neither white MTA (WMTA nor gray MTA (GMTA showed any toxic effects in this cell line. On the other hand all three cements (undiluted 48-h and 72-h extracts were cytotoxic against Saos-2 cell line. The oxidative stress marker (MDA was proportionate to the cytotoxic effects of CEM while there was no significant changes in reductive capacity of the media measured by FRAP in both cell lines.The cytotoxic effects of CEM on L929 and Saos-2 cell lines seems to be higher than WMTA and GMTA and it is increased by the time of extraction up to 72-h.. However, CEM, WMTA and GMTA showed similar toxic effect in Saos-2 cell line proportionate to the oxidative stress measured by TBARS. It seems that while all three cements extracts don't change the antioxidant activity of the media, they could significantly increase lipid peroxidation, especially CEM with Saos-2 cell line which elucidate triggering oxidative stress mechanisms without having direct oxidative activity.

    2014-03-01

    Full Text Available Statement of Problem: One of the most challenging procedural accidents during pulpotomy of primary molars is furcal perforation. To prevent bacterial invasion, the perforation site should be sealed as soon as possible. Purpose: The aim of the current study is to investigate the ability of the pro- root MTA and new endodontic cement (NEC in repairing the furcation perforations of primary molar teeth. Materials and Method: In this in vitro study, 42 extracted primary molars were select-ed. Their roots were sectioned horizontally and standard access cavity was prepared. The orifices and the root apices were sealed with two layers of resin composite .The samples were randomly assigned into 2 groups. Six teeth were considered as the positive and the negative controls. In the experimental groups; perforation was made. In group 1 and 2, perforation site received pro- root MTA and NEC respectively. The teeth were covered by two layers of nail polish except for the external surface of the perforation site. The negative control group received no repairing material. All teeth were mounted and sterilized for 24 hours. Lower chambers were filled with sterilized Muller Hinton broth. Bacterial suspension of E-faecalis in 0.5 McFarland was prepared. Then repaired site was exposed to the bacterial suspension of E-faecalis every 3 days. All samples were inserted in an incubator at 37oC and 100% humidity. The turbidity of the samples was detected for a period of 30 days. Data were analyzed by Chi- square test. Results: 44% of samples in Pro- root group, 50% of the samples in the NEC group showed contaminations during 30 days. There was no significant difference between these two groups (p= 0.799. Conclusion: With limitations of this study, Pro- root MTA and NEC showed similar capability in sealing the furcal perforations of the primary molars.

    Introduction Cleaning and shaping of root canal does not guarantee complete disinfection of the canal, regardless of the systems and techniques used for this purpose. Therefore, it becomes mandatory for the endodontic filling materials to have a good antimicrobial potential especially against E. faecalis. This research was aimed therefore to evaluate the antibacterial efficacy and flow properties of different root canal sealers. Aim To study invitro antimicrobial activity and flow characteristics for Resin based (AH Plus), Mineral Trioxide Aggregate based (MTA Fillapex), Calcium hydroxide based (CRCS) and Flowable Gutta-Percha (Gutta Flow 2) endodontic sealers on Enterococcus faecalis. Materials and Methods Enterococcus faecalis ATCC 29212 was used to test antibacterial potential of sealers by Agar diffusion test (ADT) and Direct Contact Test (DCT). ADT was performed by punching the sealers on a well of 4×6mm diameter on Muller Hinton agar plates. These plates were inoculated with standard suspension of E. faecalis and the zone of inhibition was measured at 24 hours and after 7 days. All the sealers were prepared in accordance with the manufacturer’s recommendations. Flow of sealers was measured according to ADA specification no. 57. Results All sealers showed antibacterial activity against E. faecalis except Gutta Flow 2. At 24 hours, zone of inhibition was highest in Calcibiotic Root Canal Sealer (CRCS) and lowest in AH Plus. After 7 days the zone of inhibition decreased in AH plus, CRCS and MTA Fillapex. DCT showed a significant lower number of organisms in AH Plus, CRCS and MTA than controls at both the time intervals. Gutta Flow 2 did not show any significant antimicrobial action. Maximum and minimum flow was shown by AH Plus and CRCS respectively. Conclusion Highest microbial inhibition was shown by (CRCS), followed by MTA Fillapex and AH Plus. Gutta Flow 2 did not show any inhibition of E. faecalis by ADT. Maximum reduction in antibacterial property with

  3. Ensuring Confidentiality of Geocoded Health Data: Assessing Geographic Masking Strategies for Individual-Level Data

    Directory of Open Access Journals (Sweden)

    Paul A. Zandbergen

    2014-01-01

    Full Text Available Public health datasets increasingly use geographic identifiers such as an individual’s address. Geocoding these addresses often provides new insights since it becomes possible to examine spatial patterns and associations. Address information is typically considered confidential and is therefore not released or shared with others. Publishing maps with the locations of individuals, however, may also breach confidentiality since addresses and associated identities can be discovered through reverse geocoding. One commonly used technique to protect confidentiality when releasing individual-level geocoded data is geographic masking. This typically consists of applying a certain amount of random perturbation in a systematic manner to reduce the risk of reidentification. A number of geographic masking techniques have been developed as well as methods to quantity the risk of reidentification associated with a particular masking method. This paper presents a review of the current state-of-the-art in geographic masking, summarizing the various methods and their strengths and weaknesses. Despite recent progress, no universally accepted or endorsed geographic masking technique has emerged. Researchers on the other hand are publishing maps using geographic masking of confidential locations. Any researcher publishing such maps is advised to become familiar with the different masking techniques available and their associated reidentification risks.

  9. 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.

  10. 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.

    2001-12-01

    The aim of this study is to describe the attitudes and practices of doctors and families regarding the use of the individual child health journal, especially by exploring the contradictions between the validity and confidentiality of its content, in particular with respect to HIV infection. In order to accomplish this, both doctors (N = 380) and families (N = 242) were questioned, most of them living and working in Seine-Saint-Denis, the metropolitan district with the third highest prevalence rate of HIV. The findings indicate that: most families are not always prepared to make sure that the confidential use of the child's health journal is maintained, and even less so those affected by HIV; doctors refrain from recording certain psychological and even medical data in the child health journal for fear of the information's misuse within the social sphere; doctors as well as families expressed their preoccupations concerning the confidentiality of the child health journal, essentially with respect to its content and how it is used in various contexts. A number of possibilities are proposed by the study's participants: establish a vaccination record separate from the child health journal, educate parents on how to maintain its confidential use and train the health workers to this end.

  3. Analysis of the ethical aspects of professional confidentiality in dental practice

    Full Text Available 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.

  4. Informative privacy and confidentiality for adolescents: the attitude of the Flemish paediatrician anno 2010.

    Confidentiality is a major issue in adolescent healthcare, and its perceived absence may be the main barrier for an adolescent to seek medical care. Little is known about the right on informative privacy and confidentiality for adolescents in Belgium, although these rights are unambiguously foreseen in the law on patients' rights since 2002. There are no data available regarding the introduction of a private moment with the physician during a consultation, about the nature and the quantity of information made available to parents by the paediatricians regarding the health situation of adolescents and about the existence of procedures with regard to these matters. The purpose of this study is to map out the current interpretation and the attitude of the paediatrician with regard to the right to confidentiality and informative privacy. The answers of 117 Flemish paediatricians to an anonymous questionnaire were analyzed. An unaccompanied medical visit is not frequent in Belgium (only 1%). Only 35.1% of the paediatricians systematically offer the possibility to have a private conversation with an adolescent. Almost 80% of the paediatricians render, as a rule, all information to the parents. Parents are informed about sensible information regarding psychosocial aspects, including data concerning sexual behaviour, in not less than 83.2% of the consultations by adolescents. Only in 2.9% no information is given to the parents. The paediatricians employ only for 13% the procedures regarding confidentiality for minors. This study reveals that Flemish paediatricians have a paternalistic attitude concerning the right on confidentiality and informative privacy, which is not in line with the Belgian legislation. Paediatricians offer only seldom the possibility for a private conversation to the adolescent. The small incidence of unaccompanied medical consultations contributes to this. Proper application of the legal context, the handling of the watertight procedures and the

    Introduction: The aim of this randomized clinical trial was to compare the histologic pulp tissue response to one-step direct pulp capping (DPC) and miniature pulpotomy (MP) with mineral trioxide aggregate (MTA) after application of dexamethasone in healthy human premolars. Methods and Materials: Forty intact premolars from 10 orthodontic patients, were randomly chosen for DPC (n=20) or MP (n=20). In 10 teeth from each group, after exposure of the buccal pulp horn, topical dexamethasone was applied over the pulp. In all teeth the exposed/miniaturely resected pulp tissue was covered with MTA and cavities were restored with glass ionomer. Teeth vitality was evaluated during the next 7, 21, 42, and 60 days. Signs and/or symptoms of irreversible pulpitis or pulp necrosis were considered as failure. According to the orthodontic schedule, after 60 days the teeth were extracted and submitted for histological examination. The Kruskal-Wallis and Fisher’s exact tests were used for statistical analysis of the data (P=0.05). Results: Although dexamethasone specimens showed less inflammation, calcified bridge, pulpal blood vasculature, collagen fibers and granulation tissue formation were not significantly different between the groups (P>0.05). Conclusion: Topical dexamethasone did not hindered pulp healing but reduced the amount of underlying pulpal tissue inflammation after DPC and MP in healthy human premolars. PMID:27141213

    2013-12-01

    Full Text Available This study considers the status of collective agreements under Nigerian labour law, examining the extent of their enforceability under the extant laws. It considers the emerging trends in some more advanced jurisdictions of the world in that regard and comparatively portrays the anachronisms of the Nigerian law on the point. It takes the position that the current legal climate as regards the legal status of collective agreements under Nigerian law is potentially disruptive of industrial peace and harmony and is bound to occasion serious hardship on employees. The work suggests among others a jurisprudential shift in paradigm if the Nigerian labour jurisprudence must meet and be reflective of modern socio-economic realities.

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

    Energy Technology Data Exchange (ETDEWEB)

    Loudon, Robert [Cadogan Consultants (United Kingdom)

    2001-03-01

    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.

    2013-10-01

    Full Text Available Aim: This paper refers to the decision made by the Greek Government to publish photographs and personal data of HIV positive sex workers on the grounds of protecting public health. Method: Initially, the law and theoretical background of medical confidentiality and its break were reviewed and then the conditions and data that led to the specific decision made by the Greek Authorities were investigated. Also the contribution of NGOs in the prevention of Public Health was studied. Conclusion: The survey showed that in this particular case the break of confidentiality was excessive and biased due to the origin and illegal activity of the women. A proper solution to the HIV/AIDS outbreak would be the intensification of prevention. In this sector, NGOs can and should play an active role considering that the primary care in Greece, especially during the economic crisis, shows organizational and operational weaknesses.

    2005-01-01

    Objectives: This study aimed to describe family doctors' attitudes to confidentiality and providing patient information to relatives as well as their justifications for sharing information. Method: A descriptive postal questionnaire was self-administered by family doctors. Results: Of 227 doctors, 95.1% provided information to a patient's family and over a third (35%) disclosed information to others without prior patient consent. Conclusions: The findings reveal that family doctors should pay more attention to their patients' rights to information, privacy, and confidentiality, and reflect very carefully on the fine balance between this and the occasional need for the support and collaboration of family members in delivery of care. Emphasis should be placed on ethics and legal problems during undergraduate education and in-service training of doctors. PMID:16131555

  11. 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

  12. Approaching confidentiality at a familial level in genomic medicine: a focus group study with healthcare professionals

    Science.gov (United States)

    Dheensa, Sandi; Fenwick, Angela; Lucassen, Anneke

    2017-01-01

    Objectives Clinical genetics guidelines from 2011 conceptualise genetic information as confidential to families, not individuals. The normative consequence of this is that the family's interest is the primary consideration and genetic information is shared unless there are good reasons not to do so. We investigated healthcare professionals' (HCPs') views about, and reasoning around, individual and familial approaches to confidentiality and how such views influenced their practice. Method 16 focus groups with 80 HCPs working in/with clinical genetics services were analysed, drawing on grounded theory. Results Participants raised seven problems with, and arguments against, going beyond the individual approach to confidentiality. These problems fell into two overlapping categories: ‘relationships’ and ‘structures’. Most participants had never considered ways to—or thought it was impossible to—treat familial genetic information and personal information differently. They worried that putting the familial approach into practice could disrupt family dynamics and erode patient trust in the health service. They also thought they had insufficient resources to share information and feared that sharing might change the standard of care and make them more vulnerable to liability. Conclusions A familial approach to confidentiality has not been accepted or adopted as a standard, but wider research suggests that some of the problems HCPs perceived are surmountable and sharing in the interest of the family can be achieved. However, further research is needed to explore how personal and familial genetic information can be separated in practice. Our findings are relevant to HCPs across health services who are starting to use genome tests as part of their routine investigations. PMID:28159847

    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.

  16. 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.

    Full Text Available The purpose of this study was to evaluate the penetration of three dyes in MTA root-end fillings. In 30 single-rooted teeth, cavities for retrofilling were prepared with an ultrasound appliance and filled with MTA. The specimens were randomly assigned to three groups (n = 10 and immersed in the following solutions: 2% methylene blue (MET, 50% silver nitrate (NIT and 0.2% rhodamine B (ROD. Two transversal slices (1 mm of the retrofilling region were obtained and evaluated using the Image Tool 3.0 software to obtain a quantitative evaluation (in mm² of the dye penetration around the retrofillings. Data were submitted to statistical analysis using Student’s t-test. The lowest degree of dye penetration was observed for the NIT group, in both slices (p A proposta deste trabalho foi avaliar a penetração de três corantes em retrocavidades obturadas com MTA.

    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.

    2011-01-01

    The security of bio-metric information - finger print, retina mapping, DNA mapping and some other chemical and biological modified genes related information - transfer through low bandwidth and unreliable or covert channel is challenging task. Therefore, Security of biometric information is essential requirement in this fast developing communication world. Thus, in this paper, we propose efficient and effective mechanism for confidentiality and authentication for biometric information transmitted by using arithmetic encoding representation over low bandwidth and unreliable channel. It enhances the speed of encryption, decryption and authentication process. It uses arithmetic encoding scheme and public key cryptography e.g. modified version of RSA algorithm called RSA-2 algorithm.

    was employed to estimate absolute differences in prevalence of belief in whether or not adolescents would find confidentiality important when consulting a physician on SRH issues. A log-binomial regression model was fitted to estimate the relative changes (prevalence ratio) of the independent variables....... RESULTS: The total number of respondents was 1054 (response rate 83%) in 2005 and 1002 (response rate 80%) in 2012. The proportion of respondents who reported a belief that adolescents would find confidentiality important when seeing a physician for SRH issues increased significantly from 62% in 2005...... to 73% in 2012. Regardless of their belief in the importance of confidentiality, in 2012 respondents more often indicated positive outcomes on the relations between the physician and the minor patient, such as increased trust of the adolescent in the physician and more frequent visits to physicians...

  5. 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...

    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.

  9. [When the violation of medical confidentiality is imposed by law: Another side effect of Law N° 20.584].

    Science.gov (United States)

    Vega, Jorge; Quintana, María Soledad

    2016-02-01

    A law of rights and duties of patients was recently enacted in Chile (Law N° 20.584). When someone dies, the law allows his inheritors to have access to part or the totality of the medical record. Therefore, they may become acquainted of information that the patient gave in confidence to his physician, protected by "the medical confidentiality". The original bill included the possibility that a doctor could deny information that could cause harm to the former holder of the clinical record, but this precaution was banned by congressmen, seriously damaging the institution of "medical confidentiality", a cornerstone of the medical-patient relationship since the beginning of medicine.

  10. AN IMPROVED AUTHENTICATED KEY AGREEMENT PROTOCOL

    Institute of Scientific and Technical Information of China (English)

    2005-01-01

    In 1999, Seo and Sweeney proposed a simple authenticated key agreement protocol that was designed to act as a Diffie-Hellman key agreement protocol with user authentication.Various attacks on this protocol are described and enhanced in the literature. Recently, Ku and Wang proposed an improved authenticated key agreement protocol, where they asserted the protocol could withstand the existing attacks. This paper shows that Ku and Wang's protocol is still vulnerable to the modification attack and presents an improved authenticated key agreement protocol to enhance the security of Ku and Wang's protocol. The protocol has more efficient performance by replacing exponentiation operations with message authentication code operations.

  13. Cloudy confidentiality: clinical and legal implications of cloud computing in health care.

    Science.gov (United States)

    Klein, Carolina A

    2011-01-01

    The Internet has grown into a world of its own, and its ethereal space now offers capabilities that could aid physicians in their duties in numerous ways. In recent years software functions have moved from the individual's local hardware to a central server that operates from a remote location. This centralization is called cloud computing. Privacy laws that speak to the protection of patient confidentiality are complex and often difficult to understand in the context of an ever-growing cloud-based technology. This article is a review of the legal background of protected health records, as well as cloud technology and physician applications. An attempt is made to integrate both concepts and examine Health Insurance Portability and Accountability Act (HIPAA) compliance for each of the examples discussed. The legal regulations that may inform care and standards of practice are reviewed, and the difficulties that arise in assessment and monitoring of the current situation are analyzed.

    Full Text Available INTRODUÇÃO: O Mineral Trióxido Agregado (MTA é composto por cimento Portland (CP e um radiopacificador (óxido de bismuto.OBJETIVO: Avaliar tempo de presa, solubilidade, pH, liberação de íons Cálcio e radiopacidade do cimento Portland puro ou associado a quatro radiopacificadores (sulfato de bário, carbonato de bismuto, óxido de bismuto e iodofórmio, comparados ao MTA branco (Angelus, Londrina, Brasil.MATERIAL E MÉTODO: A proporção empregada CP/radiopacificador foi de 4:1 em peso, (80% de cimento Portland e 20% de radiopacificador. A especificação 57 da ADA foi usada para avaliação do tempo de presa. A solubilidade foi analisada segundo a especificação ISO 6876/2001. A avaliação do pH foi realizada com peagâmetro digital e a liberação de íons Ca++foi verificada por meio de espectrofotômetro de absorção atômica. A radiopacidade foi determinada em milímetros de alumínio (mm/Al. Os resultados foram submetidos aos testes de Análise de Variância e Tukey, nível de significância 5%.RESULTADO: O sulfato de bário não alterou o tempo de presa final do CP. Radiopacidade inferior ao mínimo recomendado pelas normas da ADA nº 57 e ISO 6876/2001 foi observada para CP e CP associado com sulfato de bário. O CP associado ao iodofórmio apresentou solubilidade acima dos 3% recomendados pela ISO 6876/2001. Todos os materiais proporcionaram alcalinização do meio e promoveram liberação de íons cálcio.CONCLUSÃO: Carbonato de bismuto ou óxido de bismuto proporcionaram tempo de presa inicial, solubilidade, pH, liberação de íons Cálcio e radiopacidade adequados quando associados ao CP.

    Objective MTA observed with calcium hydroxide direct pulp capping effect of trauma in young permanent teeth before treatment. Methods Our hospital 40 cases of young permanent teeth due to trauma and accident exposed pulp were randomly divided into two groups, namely, the MTA and calcium hydroxide as the surgical treatment of capping agent for treatment and after 6 months, 1 year, 2 years and 3 years for review, analysis and evaluation of efficacy. Result After six months, one year after the review, MTA treatment groups were similar with calcium hydroxide, the difference was not statistically comparable (P>0.05); after 2 years, 3 years for review, MTA group treatment significantly better than the calcium hydroxide group, the two groups there was a significant treatment effect difference was statistically significant (P<0.05). Conclusion MTA is a good kind of drug in pulpotomy for the young permanent teeth,and its clinical effects are better than those of calium hydroxide,and it is worthwide application.%目的:观察 MTA 与氢氧化钙直接盖髓在年轻恒前牙外伤治疗中的效果。方法选取我院40例年轻恒前牙因外伤而意外露髓患者随机分成两组,分别将 MTA 及氢氧化钙作为手术治疗中的盖髓剂进行治疗,并在术后6个月、1年、2年及3年进行复查,分析评价疗效。结果术后6个月、1年后复查,MTA 组治疗效果与氢氧化钙组相似,差异在统计学上没有可比性(P >0.05);术后2年、3年进行复查, MTA 组治疗效果明显优于氢氧化钙组,两组治疗效果有显著性差异,有统计学意义(P <0.05)。结论年轻恒前牙外伤治疗中,盖髓剂应优先选择 MTA,MTA 的远期治疗效果明显优于氢氧化钙。

    2012-01-01

    This paper introduces Agreement Theorems to dynamic-epistemic logic. We show first that common belief of posteriors is sufficient for agreement in epistemic-plausibility models, under common and well-founded priors. We do not restrict ourselves to the finite case, showing that in countable structure
