Evaluation of Antibacterial Efficacy of MTA with and without Additives Like Silver Zeolite and Chlorhexidine.

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.
Serotonin controls initiation of locomotion and afferent modulation of coordination via 5‐HT7 receptors in adult rats

Experiments on neonatal rodent spinal cord showed that serotonin (5‐HT), acting via 5‐HT7 receptors, is required for initiation of locomotion and for controlling the action of interneurons responsible for inter‐ and intralimb coordination, but the importance of the 5‐HT system in adult locomotion is not clear. Blockade of spinal 5‐HT7 receptors interfered with voluntary locomotion in adult rats and fictive locomotion in paralysed decerebrate rats with no afferent feedback, consistent with a requirement for activation of descending 5‐HT neurons for production of locomotion. The direct control of coordinating interneurons by 5‐HT7 receptors observed in neonatal animals was not found during fictive locomotion, revealing a developmental shift from direct control of locomotor interneurons in neonates to control of afferent input from the moving limb in adults. An understanding of the afferents controlled by 5‐HT during locomotion is required for optimal use of rehabilitation therapies involving the use of serotonergic drugs.
Petrology, Geochemistry, Petrogenesis and Reactivation of Volcanic Tuffs at Dair El-Kahif Area, NE-Jordan

The volcanism in the western Arabian plate extends from the Red Sea through the Harrat Ash-shaam system to western Syria. The aforementioned volcanic activity produced large quantities of alkali olivine basalts and tuffaceous materials. The stratovolcano (7km) NE of Dair El-Kahif, NE Jordan has been investigated. The results show that dominant mineral phases are olivine, augite, plagioclase, magnetite and ilmenite. Chemical analysis of the whole rock tuff samples confirms alkali olivine magma origin. Low concentrations of Li and Rb in tuff samples are used as an argument against the contamination of the basaltic magma during its journey to the surface. The MgO and Mg-values (Mg/Mg+Fe²+) in samples from volcanic tuff exhibit different degrees of fractionation, which are indicated by the varying concentrations of incompatible trace elements (Ba, Rb, Sr). The thermometric evaluation of tuff determined by using pyroxene thermometers revealed a temperature range between 1022-1083°C and a pressure of 5-10 kbars. The low Mg-ratio (Mg/Mg+Fe²+) is due to fractional crystallization of olivine and pyroxene in tuff samples. The variations of incompatible elements imply derivation from a peridotite source in the upper mantle with low degree of melting (<20%). The volcanic activity took place in phases corresponding to rifting associated with the sinistral movement along the Dead Sea Transform and the later reactivation processes.
What are the essential features of resilience for informal caregivers of people living with dementia? A Delphi consensus examination

ABSTRACT Objectives: Few studies have examined what might enable or prevent resilience in carers of people with dementia. Consequently, there are limited insights as to how it should be understood, defined and measured. This creates challenges for research, and also practice in terms of how it might best be promoted. This study aimed to address these limitations and add new insights, identifying the essential features of resilience in dementia caregiving. Methods: A Delphi consensus study was conducted, consulting a multi-disciplinary panel of informal caregivers and experts with relevant professional expertise. Panellists rated the relevance of various statements addressing essential components of resilience; ‘adversity’ and ‘successful caregiving’ on a 5-point Likert scale. Based on the median and Inter Quartile Range, the most relevant statements with moderate consensus were proposed in Round 2 in which panellists selected up to five statements in order of importance. Results: Moderate consensus was reached for all statements after two rounds. Patients’ behavioural problems and feeling competent as a caregiver were selected by both caregivers and professionals as essential resilience features. Caregivers also emphasized the importance of social support, the quality of the relationship with their relative and enjoying spending time together. Professionals considered coping skills, experiencing positive aspects of caregiving, and a good quality of life of caregivers most relevant. Conclusion: The essential elements of resilience selected from multiple stakeholder perspectives can be used to select appropriate outcomes for intervention studies and give guidance to policy to support caregivers more effectively and better tailored to their needs.
Impact of the Femtosecond Laser in Line with the Femtosecond Laser-Assisted Cataract Surgery (FLACS) on the Anterior Chamber Characteristics in Comparison to the Manual Phacoemulsification

ABSTRACT Purpose: To assess the alterations of the anterior chamber conditions including laser flare photometry after femtosecond laser-assisted cataract surgery (FLACS) compared to the manual phacoemulsification. Methods: Data of n=70 FLACS (mean age 67.2 ± 8.9 years) and n=40 manual phacoemulsification (mean age 69.5 ± 9.6 years) were analyzed. The procedures were performed by LenSx Alcon, USA, and Alcon Infiniti Vision System, USA. The following parameters were recorded: laser flare photometry (Kowa FM 700, Japan), anterior chamber (AC) depth, AC volume, AC angle (Pentacam, Oculus Inc., Germany), lens density, pupil diameter, endothelial cell count and pachymetry. The analysis was performed preoperatively, immediately after femtosecond laser procedure and one day postoperatively. Results: Between FLACS and the phaco control group, there was a significant difference in the AC depth (p=0.023, 3.77 mm vs. 4.05 mm) one day postoperatively. The AC angle (p=0.016) showed a significant difference immediately after the femto laser treatment. The central and thinnest pachymetry and endothelial cell count did not show a significant difference between the two study cohorts (p=0.165, p=0.291, p=0.979). The phaco cohort (n=40) demonstrated a non-statistically significant difference in the flare photometry of 15.80 photons/ms one postoperative day compared to the FLACS group 26.62 photons/ms (p=0.322). Conclusion: In this study population, no evidence for an additive damage caused by the use of the femtosecond laser was demonstrated. Furthermore, no increase in the central and thinnest corneal thickness and no increased endothelial cell loss was demonstrated by the laser energy.
Balanced topology to cancel Tx leakage in CW radar

Balanced topology in radar front-end is presented, which can reduce Tx leakage to receiver drastically. The balanced radar front-end which is composed of a differential cross-coupled oscillator, two Lange couplers, and a Wilkinson combiner is implemented using commercially available InGaP/GaAs heterojunction bipolar transistor technology. The tuning range of voltage control oscillator is 320 MHz from 25.307 to 25.627 GHz. The peak output power is 0.8 dBm. Average Tx-to-Rx isolation is about 40.5 dB. Since the isolation of the Lange coupler is 19 dB, the additional cancellation due to balanced topology is expected to be 21.5 dB. The chip size is 1.05 /spl times/ 1.70 mm/sup 2/.
Strategies to keep working among workers with common mental disorders – a grounded theory study

Abstract Purpose: Most people with common mental disorders (CMDs) are employed and working, but few studies have looked into how they manage their jobs while ill. This study explores workers’ experiences of strategies to keep working while suffering from CMDs. Methods: In this grounded theory study, we interviewed 19 women and eight men with depression or anxiety disorders. They were 19–65 years old and had different occupations. Constant comparison method was used in the analysis. Results: We identified a core pattern in the depressed and anxious workers’ attempts to sustain their capacities, defined as Managing work space. The core pattern comprised four categories describing different cognitive, behavioral, and social strategies. The categories relate to a process of sustainability. Two categories reflected more reactive and temporary strategies, occurring mainly in the onset phase of illness: Forcing the work role and Warding off work strain. The third category, Recuperating from work, reflected strategies during both onset and recovery phases. The fourth category, Reflexive adaptation, was present mainly in the recovery phase and involved reflective strategies interpreted as more sustainable over time. Conclusions: The results can deepen understanding among rehabilitation professionals about different work-related strategies in depressed and anxious workers. Increased awareness of the meaning and characteristics of strategies can inform a person-oriented approach in rehabilitation. The knowledge can be used in clinical encounters to reflect together with the patient, exploring present options and introducing modifications to their particular work and life context. Implications for rehabilitation Self-managed work functioning in common mental disorders involves diverse strategies. Strategies interpreted as sustainable over time, seem to be reflective in the sense that the worker consciously applies and adapts the strategies. However, at the onset of illness, such reflection is difficult to develop as the worker might not want to realize their reduced functioning. Rehabilitation professionals’ awareness of different strategies can facilitate a person-centered approach and understanding of the vocational rehabilitation process.
The mechanical and thermal design for the MICE coupling solenoid magnet

The MICE coupling solenoids surround the RF cavities that are used to increase the longitudinal momentum of the muon beam that is being cooled within MICE. The coupling solenoids will have a warm-bore diameter of 1394 mm. This is the warm bore that is around the 200 MHz RF cavities. The coupling solenoid is a single superconducting coil fabricated from a copper matrix Nb-Ti conductor originally designed for MRI magnets. A single coupling magnet is designed so that it can be cooled with a single 1.5 W (at 4.2 K) cooler. The MICE cooling channel has two of these solenoids, which will be hooked together in series, for a magnet circuit with a total stored-energy of the order of 12.8 MJ. Quench protection for the coupling coils is discussed. This report also presents the mechanical and thermal design parameters for this magnet, including the results of finite element calculations of mechanical forces and heat flow in the magnet cold mass.
Consolidation of Linked Data Resources upon Heterogeneous Schemas

Linked data resources have influential roles in conducting the future of semantic web. They are growing more and more, and the amount of published data is increasing at a fast pace. It causes some new concerns arise in the context of semantic web. One of the most important issues is the large amount of data that is produced as identical entities in heterogeneous data sources by different providers. This is a barrier to intelligent applications or agents that are going to utilize linked data resources. It prevents us from utilizing the potential capacity of web of data. Linked data resources are valuable when we could exploit them altogether. Therefore, we could obviously perceive the importance of linked data integration. In this paper, we propose a new approach for linked data consolidation. It helps us to have a consolidation process even between resources with heterogeneous schemas. In this approach, we are going to find more identical instances locally. This means that we direct our instance coreference resolution around the two instances which are certainly identical. The neighbors of two similar instances are a good source for our approach to proceed. In addition, these neighbors are beneficial for estimating some similarities between concepts of two heterogeneous schemas. Keywords-Linked Data; Consolidation; Ontology; Schema; Instance.
Computing the unmeasured: an algebraic approach to Internet mapping

Distance estimation is important to many Internet applications, most notably for a WWW client that needs to select a server among several potential candidates. Current approaches to distance (i.e., time delay) estimation in the Internet are based on placing Tracer stations in key locations and conducting measurements between them. The Tracers construct an approximated map of the Internet after processing the information obtained from these measurements. This work presents a novel algorithm, based on algebraic tools, that computes additional distances, which are not explicitly measured. As such, the algorithm extracts more information from the same amount of measurement data. Our algorithm has several practical imparts. First, it can reduce the number of Tracers and measurements without sacrificing information. Second, our algorithm is able to compute distance estimates between locations where Tracers cannot be placed. This is especially important when unidirectional measurements are conducted, since such measurements require specialized equipment which cannot be placed everywhere. To evaluate the algorithm's performance, we tested it both on randomly generated topologies and on real Internet measurements. Our results show that the algorithm computes up to 50-200% additional distances beyond the basic Tracer-to-Tracer measurements.
Phosphorylation of αB-Crystallin Alters Chaperone Function through Loss of Dimeric Substructure*

Phosphorylation is the most common posttranslational modification of the α-crystallins in the human lens. These phosphorylated forms are not only important because of their abundance in aging lenses and the implications for cataract but also because they have been identified in patients with degenerative brain disease. By using mimics corresponding to the reported in vivo phosphorylation sites in the human lens, we have examined the effects of phosphorylation upon the chaperone-like properties and structure of αB-crystallin. Here we show that phosphorylation of αB-crystallin at Ser-45 results in uncontrolled aggregation. By using an innovative tandem mass spectrometry approach, we demonstrate how this alteration in behavior stems from disruption of dimeric substructure within the polydisperse αB-crystallin assembly. This structural perturbation appears to disturb the housekeeping role of αB-crystallin and consequently has important implications for the disease states caused by protein aggregation in the lens and deposition in non-lenticular tissue.
Recovering 3-D gaze scan path and scene structure from inside-out camera

First-Person Vision (FPV) is a wearable sensor that takes images from a user's visual field and interprets them, with available information about the user's head motion and gaze, through eye tracking [1]. Measuring the 3-D gaze trajectory of a user moving dynamically in 3-D space is interesting for understanding a user's intention and behavior. In this paper, we present a system for recovering 3-D scan path and scene structure in 3-D space on the basis of ego-motion computed from an inside-out camera. Experimental results show that the 3-D scan paths of a user moving in complex dynamic environments were recovered.
Cloning and characterization of bfpTVW, genes required for the transcriptional activation of bfpA in enteropathogenic Escherichia coli

Expression of the bundle‐forming pilus (BFP) of enteropathogenic Escherichia coli (EPEC) is regulated at the transcriptional level by growth phase, temperature, calcium and ammonium. Genes required for the transcriptional activation of bfpA were localized to a 1.8 kb fragment of the enteroadherent factor (EAF) plasmid of EPEC that is separated from the bfp operon by 6 kb. Within this fragment three identically oriented and closely spaced open reading frames (ORFs) were identified and designated bfpT, bfpV and bfpW. bfpT is predicted to encode a 31.8 kDa protein that shares homology with the AraC family of transcriptional regulators, including the presence of a conserved C‐terminal DNA‐binding helix‐turn‐helix motif. Insertional inactivation of bfpT led to the loss of bfpA transcription, BfpA protein production and the localized adherence (LA) phenotype; this mutant phenotype could be complemented by introduction of bfpTVW and, on separate plasmids, bfpT + bfpW. However, introduction of bfpT + bfpV, bfpV alone, bfpW alone, or bfpV + bfpW did not enable recovery of the wild‐type phenotype. Maximal efficiency of bfpA transcription required all three genes, but bfpV and bfpW each enhanced transcription providing bfpT was also present. A series of deletions of the bfpA upstream promoter region was prepared; with respect to the bfpA transcription start site, sequence between nucleotides −94 and −55 was found to bind bfpT. BfpT also bound a DNA fragment containing the eaeA promoter region on the EPEC chromosome. From these results we conclude that bfpTVW causes transcriptional activation of bfpA, and possibly eaeA, by a trans‐acting mechanism that may co‐ordinately regulate the expression of EPEC virulence determinants.
Orbitally modulated dust formation by the WC7+O5 colliding-wind binary WR 140

We present high-resolution infrared (2–18 μm) images of the archetypal periodic dust-making Wolf–Rayet binary system WR 140 (HD 193793) taken between 2001 and 2005, and multi-colour (J–[19.5]) photometry observed between 1989 and 2001. The images resolve the dust cloud formed by WR 140 in 2001, allowing us to track its expansion and cooling, while the photometry allows tracking the average temperature and total mass of the dust. The combination of the two data sets constrains the optical properties of the dust, and suggests that they differ from those of the dust made by the WC9 dust-makers, including the classical 'pinwheel', WR 104. The photometry of individual dust emission features shows them to be significantly redder in (nbL'–[3.99]) , but bluer in ([7.9]–[12.5]), than the binary, as expected from the spectra of heated dust and the stellar wind of a Wolf–Rayet star. The most persistent dust features, two concentrations at the ends of a 'bar' of emission to the south of the star, were observed to move with constant proper motions of 324 ± 8 and 243 ± 7 mas yr^−1. Longer wavelength (4.68 and 12.5 μm) images show dust emission from the corresponding features from the previous (1993) periastron passage and dust formation episode, showing that the dust expanded freely in a low-density void for over a decade, with dust features repeating from one cycle to the next. A third persistent dust concentration to the east of the binary (the 'arm') was found to have a proper motion ∼320 mas yr^−1, and a dust mass about one-quarter that of the 'bar'. Extrapolation of the motions of the concentrations back to the binary suggests that the eastern 'arm' began expansion four to five months earlier than those in the southern 'bar', consistent with the projected rotation of the binary axis and wind-collision region (WCR) on the sky. A comparison of model dust images and the observations constrains the intervals when the WCR was producing sufficiently compressed wind for dust nucleation in the WCR, and suggests that the distribution of this material was not uniform about the axis of the WCR, but more abundant in the following edge in the orbital plane.

Study on View-Oriented Navigation Modeling of Web Applications

This paper presents view-oriented navigation modeling (VONM), a system analysis method and tool for web applications. Firstly, the view was discussed as a navigation node. The view is dynamic and hierarchical. The dynamic characteristic means that a view may render varied objects and state data of an object is changeable. The hierarchy of the view refers to the feature that a more abstract view may be refined to produce several more concrete views. Then, the paper analyzed the classification and the features of navigation. Non-action navigation is the navigation in the traditional sense. Action navigation is also navigation, but its primary purpose is to perform a specific data processing. In this work, the model is made up of view diagrams, navigation diagrams and specification cards for view or navigation. Finally, the paper introduced some navigation implement patterns for the action navigation. DOI : http://dx.doi. org/10.11591/telkomnika.v12i3. 4522 Full Text: PDF
An alar rim defect.

A65-year-old man underwent 3 stages of Mohs micrographic surgery for a primary basal cell carcinoma (BCC) of the left alar rim. The final defect measured 0.8 · 0.5 cm and involved full thickness of the dermis (Figure 1). The underlying nasal lining remained intact. The case was potentially complicated by thick sebaceous skin of the nose and an old cheek advancement flap for a superio-lateral ala and sidewall BCC. How would you reconstruct this defect?
A 6-GHz integer frequency synthesizer for SATA III applications in 0.18-μm CMOS technology

In this paper, a 6-GHz frequency synthesize (FS) for SATA III application by using 0.18-μm CMOS technology is presented. Multi-modulus divider (MMD) is utilized to achieve the function of spreading spectrum of SATA III. The complementary voltage-controlled oscillator (VCO) is adopted for phase noise consideration. In order to reduce the locking time of spreading spectrum, the loop bandwidth is increased as large as possible. Based on the aforementioned techniques, the measured free-running phase noise and closed-loop phase noise of the proposed FS are -112 dBc/Hz and -80 dBc/Hz at 1-MHz offset frequency, respectively. The total dc power consumption is 25.2 mW.
