Three-Dimensional Mapping-Guided Implantation of an Atrial Pacing Lead in a Dilated Scarred Quiescent Right Atrium Following CHD Repair

A 41-year-old male born with complex congenital heart defects after multiple cardiac surgeries presented with symptomatic sinus node dysfunction and atrial flutter. Prior to pacemaker implantation, he was detected to have elevated central venous pressures and dilated scarred quiescent right atrium (RA). Three-dimensional mapping of the RA was carried out during the electrophysiology study and was used to target the site of atrial lead implantation for pacing the RA as there was only a small area of electrically active atrial tissue with adequate sensing and pacing. This simple, innovative technique for lead implantation can be used to target specific sites in certain cases.
Evidence-Based Practice An Introduction Peter Sturmey Evidence-Based Practice

Questions concerning evidence-based practice (EBP) permeate services for people with developmental disabilities. A parent must decide whether or not to participate in early intervention for their child with autism and stay at home instead of working. A teacher selects certain target behaviors and teaching strategies for a child and decides not to teach other skills and not to use other teaching strategies. An agency for adults with disabilities decides whether to operate traditional, center-based services or to implement a new job coaching service. A city, state, or government agency decides whether or not to fund early intervention or to place some individuals in specialized, expensive, out-of-district services. EBP is reflected in many educational and clinical decisions by individual teams. Consider the following example. A team of professionals in special education attempt to treat food refusal in a child with autism for 6 months using sensory integration therapy. Not only did the child continue to refuse food, but the child continued to lose weight. When outside therapists proposed using escape extinction (see Chapter 8) as an EBP, the educators oppose such treatment on the grounds that it does not address the sensory needs of the child and will not work or they refuse to treat the problem by “conditioning” or “behavior modification” which they think is “inhuman” or “disrespectful. ” After 2 weeks of escape extinction, the child now ate a wide range of foods and gained weight; resources are no longer wasted on ineffective therapy and useless discussion of ineffective treatment. EBP is not some academic question. If we are concerned with personally significant outcomes and avoidance of harm for individuals with developmental 1
Low-loss air-filled Substrate Integrated Waveguide (SIW) band-pass filter with inductive posts

A low-loss band-pass filter made of inductive posts and based on air-filled Substrate Integrated Waveguide (SIW) is proposed in this work. It is implemented on a low-cost multilayer printed circuit board (PCB) process. The top and bottom layers may make use of an extremely low-cost standard substrate such as FR-4 on which base-band or digital circuits can be designed so to obtain a very compact, high performance, low cost and self-packaged integrated system. For measurement purpose, an optimized-length Ka-band dielectric-to-air-filled SIW transition with 0.23±0.06 dB insertion loss and a TRL calibration kit are introduced. The design of the proposed band-pass filter is detailed. Both third-order dielectric- and air-filled SIW band-pass filters are designed, fabricated and compared. They respectively achieve 0.56±0.24 and 0.18±0.17 insertion loss in the operating band of interest. The proposed filter is of particular interest for microwave and millimeter-wave low-noise receivers.
Tribological evaluation of nanocomposite coatings in piezoelectric contact

Piezoelectric micro-engines (PEA) are used in precise positioning equipment in medical, measurement applications, space engineering etc. Tribological processes in the friction contacts of such actuators are very important because efficiency of PEA friction pairs is influenced by roughness and hardness of the surfaces. Studies indicate that friction pairs for the reliable constant operation of PEA could be developed when using surface materials of different roughness and hardness. These parameters could be controlled by application of metallic carbides and oxides as plasma coatings. The use of tribo-active materials can decrease volumetric wear of friction surfaces and increase the reliability of PEA.

Clinical characteristics of patients with premature acute coronary syndrome and adverse cardiovascular events after PCI

Few studies have compared the clinical manifestations of patients with premature acute coronary syndrome (ACS) and late-onset ACS as well as the adverse cardiovascular events following percutaneous coronary intervention (PCI). To investigate the clinicopathological characteristics of patients with premature ACS and adverse cardiovascular events following PCI, a total of 726 patients with ACS undergoing PCI were divided into two groups: A premature ACS group and a late-onset ACS group. Following discharge, all patients were followed-up for an average of 23.5±5.3 months. Clinical characteristics, Gensini scores, vascular lesions and adverse cardiovascular events were compared between the two groups. There were no significant differences in smoking, diabetes, ACS composition ratio, baseline treatment of coronary heart disease, high-density lipoprotein level and C-reactive protein levels between the two groups. Sex and hypertriglyceridemia were determined to be independent risk factors of premature ACS, while age, hypertension and a high Gensini score were independent risk factors for adverse cardiovascular events in patients with ACS following PCI. Furthermore, the prevalence of premature ACS was significantly higher in females. Although serum levels of fasting blood glucose, total cholesterol, triglycerides and low-density lipoprotein were also significantly higher in patients with premature ACS compared with patients with late-onset ACS, patients with premature ACS exhibited fewer vascular lesions compared with patients with late-onset ACS. Furthermore, the incidence of adverse cardiovascular events in patients with ACS following PCI did not differ significantly between premature and late-onset ACS groups. Taken together, these results suggest that female patients should be closely observed for early risk factors of premature ACS to prevent and reduce the occurrence of adverse cardiovascular events in patients with ACS following PCI.
Comparison of nested PCR with immunofluorescent-antibody assay for detection of Ehrlichia canis infection in dogs treated with doxycycline

A partial 16S rRNA gene was amplified in Ehrlichia canis-infected cells by nested PCR. The assay was specific and did not amplify the closely related Ehrlichia chaffeensis, Ehrlichia muris, Neorickettsia helminthoeca, and SF agent 16S rRNA genes. The assay was as sensitive as Southern hybridization, detecting as little as 0.2 pg of E. canis DNA. By this method, all blood samples from four dogs experimentally infected with E. canis were positive as early as day 4 postinoculation, which was before or at the time of seroconversion. One hundred five blood samples from dogs from Arizona and Texas (areas of E. canis endemicity) and 30 blood samples from dogs from Ohio (area of E. canis nonendemicity) were examined by nested PCR and immunofluorescent-antibody (IFA) test. Approximately 84% of dogs from Arizona and Texas had been treated with doxycycline before submission of blood specimens. Among Arizona and Texas specimens, 46 samples were PCR positive (44%) and 80 were IFA positive (76%). Forty-three of 80 IFA-positive samples (54%) were PCR positive, and 22 of 25 IFA-negative samples (88%) were negative in the nested PCR. None of the Ohio specimens were IFA positive, but 5 specimens were PCR positive (17%). Our results indicate that the nested PCR is highly sensitive and specific for detection of E. canis and may be more useful in assessing the clearance of the organisms after antibiotic therapy than IFA, especially in areas in which E. canis is endemic.
CHLORINA MUTANTS OF BARLEY ( Hordeum vulgare

We have examined 31 new chlorina mutants of barley using in vivo absorption spectroscopy, 77 K fluorescence emission spectroscopy, room temperature fluorescence induction kinetics, HPLC separation of pigments and SDS-PAGE. Based on these properties they can be placed into 4 groups. The first group consists of 10 mutants which are allelic to the chlorophyll b-less chlorina-f2 and comprises five strongly and three slightly leaky mutants at this locus. The decrease in chlorophyll b content was correlated with a corresponding decrease in the amount of chlorophyll a/b-proteins in the thylakoids. One mutant (chlorina 106) was found which had a very low chlorophyll b content and a deficiency in Chl,/~-P2, but was not allelic to chlorina-f2. The second group of chlorina mutants has unusual fluorescence properties, with a high Fm/Fo ratio. Gaussian deconvolution of the 77 K fluorescence emission spectra revealed an increase in the amplitude of components emitting at 694 and 718 rim. The possibility is discussed that these properties result from the absence of the PSI connecting antenna LHCI-680. The third group has a Fs/Fo ratio < 1, and other properties consistent with a partial deficiency in the chlorophyll a-proteins of PSII reaction centres. The fourth group consists ofchlorina mutants which are very similar to wild-type in the properties examined, differing mainly in having a lower chlorophyll content.
Uncertainty , Disagreement and Bond Risk Premia

This paper studies the link between sovereign bond risk premia and uncertainty measures extracted from a large international panel of professional survey forecasts. We show evidence that future shortterm interest rate uncertainty that is not spanned by future short term and contemporaneous macro uncertainty significantly affects bond risk premia. Because our measure is based on the cross-sectional dispersion of individual forecasts this points to the importance of disagreement. While we do not identify policy reaction functions, our results suggest a larger role for uncertainty and disagreement about future monetary policy than has been considered thus far in the term structure literature. In particular, the evidence in favour of policy uncertainty is more robust than for the role of inflation uncertainty, and is similar using different surveys, several additional controls, sample period and countries.

Disruption of right posterior parietal cortex by continuous Theta Burst Stimulation alters the control of body balance in quiet stance

Control of body balance relies on the integration of multiple sensory modalities. Lightly touching an earth‐fixed reference augments the control of body sway. We aimed to advance the understanding of cortical integration of an afferent signal from light fingertip contact (LT) for the stabilisation of standing body balance. Assuming that right‐hemisphere Posterior Parietal Cortex (rPPC) is involved in the integration and processing of touch for postural control, we expected that disrupting rPPC would attenuate any effects of light touch. Eleven healthy right‐handed young adults received continuous Theta Burst Stimulation over the left‐ and right‐hemisphere PPC with sham stimulation as an additional control. Before and after stimulation, sway of the blindfolded participants was assessed in Tandem‐Romberg stance with and without haptic contact. We analysed sway in terms of the variability of Centre‐of‐Pressure (CoP) rate of change as well as Detrended Fluctuation Analysis of CoP position. Light touch decreased sway variability in both directions but showed direction‐specific changes in its dynamic complexity: a positive increase in complexity in the mediolateral direction coincided with a reduction in the anteroposterior direction. rPPC disruption affected the control of body sway in two ways: first, it led to an overall decrease in sway variability irrespective of the presence of LT; second, it reduced the complexity of sway with LT at the contralateral, non‐dominant hand. We speculate that rPPC is involved in the active exploration of the postural stability state, with utilisation of LT for this purpose if available, by normally inhibiting mechanisms of postural stiffness regulation.
Comparison of Effectiveness of Stabilization Splint , Anterior Repositioning Splint and Behavioral Therapy in Treatment of Disc Displacement with Reduction

Objective: Splint therapy is a proven modality for many types of temporomandibular joint (TMJ) disorders. Stabilization and anterior repositioning splints are often the choice of treatment for disc displacement with reduction. The aim of this study was to compare the efficacy of behavioral therapy, stabilization and anterior repositioning splints in patients with disc displacement with reduction. Materials and Methods: The subjects (n=105) were selected from the patients who were referred to the TMJ Diseases Clinic over a period of two years. The Research Diagnostic Criteria for Temporomandibular Disorders were used for evaluation. The patients were instructed to use their splints only during the night. All patients were scheduled for a total of seven follow-up visits within six months. Seventy-two patients who completed their scheduled visits were examined for subjective and objective symptoms. Results: The subjective symptoms (graded chronic pain scale) and objective symptoms (assisted and unassisted maximum opening, TMJ sounds, muscle and joint palpation tenderness) improved in all treatment groups. However, no significant differences have been observed between the groups. Conclusion: According to the results of this study, it can be concluded that behavioral therapy and splint therapies are both good choices for the treatment of disc displacement with reduction.

MAGNETIC SENSOR ARRAY FOR INVESTIGATIONS OF MAGNETIC FIELD DISTRIBUTION

For investigations of magnetic field distribution various scanning systems have been developed – for example MagScan system [1], Magnetovision system [2 ,3] or Scanning Hall Probe Microscope [4,5]. For improv e speed of the magnetic field investigations (especia lly in the case of varying fields) much better would be to use magnetic sensor array. Unfortunately in the case of magnetic sensor arrays we do not observe such progr ess as in the case of optical sensors (cameras with mat rix larger than 10 Mega pixels or optical scanners with resolution better than 2400 dpi). There are reported designs of magnetic sensor array composed of Hall sensors [6], MagFet sensors [7] or coil sensors [8], but there are not market available suc h sensors. Lately manufacturer of GMR sensors Nonvola tile Electronics Company presented design of sensor arra y (but to date also such sensors are not available). Thus at last investigators have to prepare such sensor matr ix by themselves.
Occupational injury mortality: New Mexico 1998-2002.

BACKGROUND The current study characterizes patterns of occupational injury fatalities in New Mexico for the 5-year period 1998-2002. METHODS The study applied methods developed by the Council of State and Territorial Epidemiologists/National Institute for Occupational Safety and Health (CSTE/NIOSH) Occupational Health Indicator Work Group and compared the relative strength and weakness of two different datasets (CFOI and NMVRHS) for occupational injury fatality surveillance. RESULTS Annual occupational injury mortality rates ranged from 4.4 to 7.6 per 100,000 employed persons aged 16 and over compared to annual US rates of 4.0-4.6 per 100,000. Risk factors for higher mortality rates included age over 65 years, self-employment, non-US citizenship, being African-American or Hispanic, and occurrence in rural counties. The top industry for fatality rate was mining followed by transportation, public utilities, agriculture, and construction. CONCLUSIONS Applying CSTE/NIOSH Occupational Health Indicator protocol and using both CFOI and NMVRHS data improved the characterization of occupational injury mortality and the setting of priorities for prevention intervention.
Evolution of plasmid-coded resistance to broad-spectrum cephalosporins

A clinical isolate of Klebsiella ozaenae with transferable resistance to broad-spectrum cephalosporins produces a beta-lactamase determined by plasmid pBP60. The beta-lactamase had the same isoelectric point as SHV-1 (7.6). From heteroduplex analysis, an extensive homology between the two bla genes could be deduced; therefore, the new beta-lactamase was designated SHV-2. Enzymatic studies revealed that SHV-2 was able to hydrolyze broad-spectrum cephalosporins due to an increased affinity of these compounds for the enzyme. The assumption that SHV-2 is a natural mutant of SHV-1 was strongly supported by the isolation of a laboratory mutant of SHV-1 that showed activities similar to those of SHV-2.
Outcomes of resected pancreatic cancer in patients age ≥70.

OBJECTIVE To determine outcomes of patients ≥70 years with resected pancreatic cancer. METHODS A study was conducted to identify pancreatic cancer patients ≥70 years who underwent surgery for pancreatic carcinoma from 2000 to 2012. Patients were excluded if they had neoadjuvant therapy. The primary endpoint was overall survival (OS). RESULTS We identified 112 patients with a median follow-up of surviving patients of 36 months. The median patient age was 77 years. The median and 5 year OS was 20.5 months and 19%, respectively. Univariate analysis (UVA) showed a significant correlation for increased mortality with N1 (P=0.03) as well as post-op CA19-9 >90 (P<0.001), with a trend towards decreased mortality with adjuvant chemoradiation (P=0.08). Multivariate analysis (MVA) showed a statistically significant increased mortality associated with N1 (P=0.008), post-op CA19-9 >90 (P=0.002), while adjuvant chemoradiation (P=0.04) was associated with decreased mortality. CONCLUSIONS These data show that in patients ≥70, nodal status, post-op CA19-9, and adjuvant chemoradiation, were associated with OS. The data suggests that outcomes of patients ≥70 years who undergo upfront surgical resection are not inferior to younger patients.
Integrated modelling of ITER scenarios with D-T Mix control

An analysis of D and T fuelling requirements for DT mix control for ITER H-mode plasmas is performed including the use of pellet injection for core plasma fuelling and ELM pacing with gas fuelling for edge density and divertor power load control based on the ITER fuelling and pumping systems capabilities [1]. Simulations are carried out by 1.5D core transport modelling with individual treatment of D and T ions and discrete pellet modelling [2] with ASTRA suite of codes [3]. Plasma parameters at the separatrix and particle sources from gas puffing are derived from scalings based on SOLPS simulations [4]. The width and height of the pedestal were fitted following EPED1+SOLPS scaling prediction [5]. The anomalous transport was calculated by the TGLF model [6]. The TGLF model is benchmarked against the GLF23 model [8] predictions for a comparable case of DD ITER operation. The studies of sensitivity of the DT mix and density control to pellet injection parameters is carried out. Transport model description The simulations carried out by 1.5D core transport modelling with ASTRA suite of codes [3] comprise self-consistent modelling of 2D equilibrium and 1D transport for densities of the charged particle species, electron and ion temperatures Te, Ti, and poloidal magnetic flux, . Particle transport solver was modified to calculate 4 individual ion species, nD, nT, nHe, nNe, including individual treatment of D and T ions and calculation of the electron density from the quasi-neutrality condition: ne =  Zkni,k, i,k = D, T, He, Ne. Boundary conditions at the separatrix and particle sources from gas puffing are derived as functions of the particle and power fluxes to the SOL based on the SOLPS simulations [4]. The anomalous diffusivities in the edge transport barrier additional to the neoclassical transport are tuned to provide the time averaged pedestal pressure following EPED1+SOLPS scaling 45 EPS Conference on Plasma Physics P5.1050
Noninvasive Measurement of Retrograde Conduction Times in Pacemaker Patients

Retrograde, or ventriculoatrial conduction (VAC) has been measured in 67% of pacemaker patients with SSS and 25% of patients with 3° block.1 DDD pacers use the postventricular atrial refractory period [PVAHP] to prevent sensing VAC. If the PVARP is too short, a pacer‐mediated tachycardia (PMT) could occur. If too long, rapid atrial rates may not be sensed. To accurately set the PVARP, VAC must be measured. Five noninvasive methods are described: (1) Surface ECG during WI pacing; (2) Atrial intracardiac electrograms during WI pacing; (3) Initiating a PMT with long pacemaker AV interval; (4) Initiating a PMT at the maximum tracking rate; (5) DDI mode with electronic calipers. The description of these methods is intended to enable a physician to detect and measure VAC in patients with any manufacturer's DDD or VDD pacemaker.
A Review of Antenna Design for Millimeter Wave Range

Due to great demand on data rate and bandwidth utilization in RF communication systems, recent research studies leads to the development of millimeter wave frequency range i.e. 30Ghz to 300 GHz. This paper focused on reviewing various millimeter wave antenna design and comparing the antenna parameter. These antennas were designed using various simulators such as HFSS, ADS and CST.
