Diesel Oil Degradation Potential of a Bacterium Inhabiting Petroleum Hydrocarbon Contaminated Surface Waters and Characterization of Its Emulsification Ability
Authors: Onur Gozde , Yilmaz Fadime , Icgen Bulent 
Published: May 2015

AbstractDegradation of poorly water soluble hydrocarbons, like n‐alkanes and polycyclic aromatic hydrocarbons are challenged by some bacteria through emulsification of hydrocarbons by producing biosurfactants. In diesel oil bioremediation, diesel oil degrading and surfactant producing bacteria are used to eliminate these pollutants from contaminated waters. Therefore, identifying and characterizing bacteria capable of producing surfactant and degrading diesel oil are pivotal. In this study, bacteria isolated from hydrocarbon contaminated river water were screened for their potential to degrade diesel oil. Primary selection was carried out by using conventional enrichment culture technique, emulsification index measurement, gravimetric and gas chromatographic analyses of diesel oil degradation. A bacterium with 60 % emulsification index and 92 % diesel oil degradation ability in 14 days was identified as Acinetobacter haemolyticus Zn01 by 16S rRNA sequencing. A. haemolyticus Zn01 was shown to harbor both catabolic genes alkB and C23O effective in diesel oil degradation. The biosurfactant of the bacterium was also characterized in terms of surface tension, zeta potential, Fourier transform infrared spectroscopy and scanning electron microscopy. Being able to emulsify and degrade diesel oil, A. haemolyticus Zn01 seems to have high potential for the elimination of diesel oil from polluted waters.
Guideline Implementation: Local Anesthesia
Authors: Fencl Jennifer L. 
Published: May 2015

AbstractIt is not uncommon in perioperative settings for patients to receive local anesthesia for a variety of procedures. It is imperative for patient safety that the perioperative RN has a comprehensive understanding of best practices associated with the use of local anesthesia. The updated AORN “Guideline for care of the patient receiving local anesthesia” provides guidance on perioperative nursing assessments and interventions to safely care for patients receiving local anesthesia. This article focuses on key points of the guideline to help perioperative personnel become knowledgeable regarding best practice as they care for this patient population. The key points address patient assessment, the importance of having an overall understanding of the local agent being used, recommended monitoring requirements, and potential adverse events, including life‐threatening events. Perioperative RNs should review the complete guideline for additional information and for guidance when writing and updating policies and procedures.

Authors: Martins Marielle Rodrigues , dos Santos Carlos Henrique Marques , Falcão Gustavo Ribeiro 
Published: May 2015

AbstractHirschsprung's disease is a condition characterized by the absence of ganglion cells in a variable segment of the large intestine, mainly producing the symptom of constipation and being usually diagnosed in the first year of life. With diagnostic methods already established in the literature, the sole treatment is surgery. The objective of this study is to report a case of late diagnosis of the disease at age 13, with symptoms of fecal incontinence in its evolution.
‘Eternity will nail him to himself’: the logic of damnation in Kierkegaard'sThe Sickness unto Death
Authors: MANIS R. ZACHARY 
Published: May 2015

AbstractThough Kierkegaard's writings are rarely referenced in discussions of the problem of hell, the choice model of hell, I argue, can be strengthened by a close reading of the relevant passages ofThe Sickness unto Deaththat bear on the topic of damnation. Each of the two major forms of the choice model that are discussed in the contemporary philosophical literature are anticipated and developed in masterful psychological detail in this key Kierkegaardian text. The first form of the choice model, which sees damnation as the explicit and direct object of choice of those who are finally lost, faces the challenge of explaining motive: why would anyone freely choose eternal damnation? The second form, in which damnation is the natural consequence of certain free choices but not that which is chosen directly, faces the significant challenge of explaining why God does not annihilate the damned, mercifully putting them out of their misery. I argue thatThe Sickness unto Deathcontains conceptual resources for meeting both of these challenges.

Published: May 2015

ABSTRACTImmigration disrupts the bonding process in families. Maintaining close relationships with adult children can be an important protective factor for older immigrants' health and wellbeing. Quantitative research explaining such close relationships is rare. This study examined factors associated with close parent–child relationships in a purposive sample of 236 older Chinese immigrants in Los Angeles who provided information regarding 365 children. Two-level regression models were estimated to investigate factors contributing to cohesive parent–child relationships among these older adults. The findings showed that co-residence, a characteristic that distinguishes immigrant families from most non-immigrant families, was associated with lower parent–child relationship quality. Frequent contact was associated with closer relationships. While receiving instrumental and monetary support from children was associated with favourable ratings of relationships with children, providing such support to children was not related to parents' assessment of relationship quality. Parental perceptions of children being respectful was also associated with better relationship quality ratings. Overall, the findings demonstrate how family-related changes in the immigration context shape parent–child relationships in later life. Implications for future research and practice are provided.

AbstractMonitoring the rate of ice flow into ice shelves is vital to understanding how, where and when mass changes occur in Antarctica. Previous observations of ice surface velocity indicate that the Amery Ice Shelf and tributary glaciers have been relatively stable over the period 1968 to 1999. This study measured the displacement of features on the ice surface over a sequence of Landsat 7 images separated by approximately one year and spanning 2004 to 2012 using the surface feature tracking software IMCORR. The focus is on the region surrounding the southern grounding zone of the Amery Ice Shelf and its primary tributary glaciers: the Fisher, Lambert and Mellor glaciers. No significant changes in surface velocity were observed over this period. Accordingly, the velocity fields from each image pair between 2004 and 2012 were used to synthesize an average velocity dataset of the Amery Ice Shelf region and to compare it to previously published velocity datasets and in situ global positioning system velocity observations. No significant change in ice surface velocities was found between 2004 and 2012 in the Amery Ice Shelf region, which suggests that it continues to remain stable.
Motivational Interviewing: Ein Literaturüberblick
Authors: Demmel Ralf 
Published: May 2015

Der dysfunktionale Konsum psychotroper Substanzen geht in der Regel mit einem Zwiespalt zwischen Abstinenzvorsatz bzw. der Absicht, den Konsum zu reduzieren, einerseits und dem Wunsch oder Zwang, den Konsum fortzusetzen, andererseits einher. Das von Miller und Rollnick (1991) beschriebene Motivational Interviewing (MI) ist ein zugleich klientenzentrierter und direktiver Behandlungsstil, der dieser Ambivalenz Rechnung tragen und somit Veränderungsbereitschaft erhöhen soll. Miller und Rollnick (1991) nennen fünf Prinzipien motivationaler Gesprächsführung: <OL><LI>Empathie, <LI>Widersprüche aufzeigen, <LI>Wortgefechte vermeiden, <LI>Nachgiebig auf Widerstand reagieren und <LI>Selbstwirksamkeit fördern.</OL> Diese Prinzipien stimmen mit den Annahmen (sozial-) psychologischer Modelle der Einstellungs- und Verhaltensänderung überein. Seit Ende der achtziger Jahre wurden vorwiegend in den angelsächsischen Ländern verschiedene motivationale Interventionen zur Sekundärprävention und Behandlung von Substanzabhängigkeit und -missbrauch entwickelt, die den von Miller und Rollnick (1991) formulierten Behandlungsprinzipien entsprechen (der Drinkers Checkup, Motivational Enhancement Therapy, das Harm-Reduction-Programm BASICS, Brief Motivational Interviewing, Brief Negotiation sowie eine Reihe weiterer motivationaler Kurzinterventionen). Vor dem Hintergrund der bislang vorliegenden Literatur erscheint insbesondere die Durchführung standardisierter motivationaler Interventionen zur Reduktion dysfunktionalen Alkoholkonsums bzw. der negativen Konsequenzen eines fortgesetzten Alkoholmissbrauchs gerechtfertigt. Voraussetzungen einer Optimierung des Behandlungserfolgs sind neben der Identifikation zentraler Wirkmechanismen u.a. eine fortlaufende Prozess-Evaluation der Implementierung motivationaler Interventionen sowie eine evidenzbasierte Ausbildung.

AbstractIn bacteria, selective promoter recognition by RNA polymerase is achieved by its association with σ factors, accessory subunits able to direct RNA polymerase “core enzyme” (E) to different promoter sequences. Using Chromatin Immunoprecipitation-sequencing (ChIP-seq), we searched for promoters bound by the σS-associated RNA polymerase form (EσS) during transition from exponential to stationary phase. We identified 63 binding sites for EσS overlapping known or putative promoters, often located upstream of genes (encoding either ORFs or non-coding RNAs) showing at least some degree of dependence on the σS-encoding rpoS gene. EσS binding did not always correlate with an increase in transcription level, suggesting that, at some σS-dependent promoters, EσS might remain poised in a pre-initiation state upon binding. A large fraction of EσS-binding sites corresponded to promoters recognized by RNA polymerase associated with σ70 or other σ factors, suggesting a considerable overlap in promoter recognition between different forms of RNA polymerase. In particular, EσS appears to contribute significantly to transcription of genes encoding proteins involved in LPS biosynthesis and in cell surface composition. Finally, our results highlight a direct role of EσS in the regulation of non coding RNAs, such as OmrA/B, RyeA/B and SibC.

Published: May 2015

AbstractTinnitus is the conscious perception of sound with no physical sound source. Some models of tinnitus pathophysiology suggest that networks associated with attention, memory, distress and multisensory experience are involved in tinnitus perception. The aim of this study was to evaluate whether a multisensory attention training paradigm which used audio, visual and somatosensory stimulation would reduce tinnitus. Eighteen participants with predominantly unilateral chronic tinnitus were randomized between two groups receiving 20 daily sessions of either integration (attempting to reduce salience to tinnitus by binding with multisensory stimuli) or attention diversion (multisensory stimuli opposite side to tinnitus) training. The training resulted in small but statistically significant reductions in Tinnitus Functional Index and Tinnitus Severity Numeric Scale scores and improved attentional abilities. No statistically significant improvements in tinnitus were found between the training groups. This study demonstrated that a short period of multisensory attention training reduced unilateral tinnitus, but directing attention toward or away from the tinnitus side did not differentiate this effect.

Published: May 2015

For demonstrating autonomous operation of the Internet of things (IoT) smart sensors, the compact folded dipole rectenna with radio frequency (RF) energy harvesting is proposed. The rectifying circuits in the proposed rectenna consist of the impedance matching network and the voltage multiplier for the optimised received power. It has achieved the RF‐dc conversion efficiency of approximately 23% when illuminated by a radio signal of 1 mW available power from the commercial UHF RFID reader.

ABSTRACT
In this paper, we present a detailed high-resolution spectroscopic study of post main sequence stars in the globular cluster (GC) M68. Our sample, which covers a range of 4000 K in

, and 3.5 dex in log(g), is comprised of members from the red giant, red horizontal, and blue horizontal branch, making this the first high-resolution GC study covering such a large evolutionary and parameter space. Initially, atmospheric parameters were determined using photometric as well as spectroscopic methods, both of which resulted in unphysical and unexpected

, log(g),

, and [Fe/H] combinations. We therefore developed a hybrid approach that addresses most of these problems, and yields atmospheric parameters that agree well with other measurements in the literature. Furthermore, our derived stellar metallicities are consistent across all evolutionary stages, with

[Fe/H]

= −2.42 (σ = 0.14) from 25 stars. Chemical abundances obtained using our methodology also agree with previous studies and bear all the hallmarks of GCs, such as a Na-O anti-correlation, constant Ca abundances, and mild r-process enrichment.
Quantum dynamics of tunneling dominated reactions at low temperatures
Authors: Hazra Jisha , Balakrishnan N 
Published: May 2015

Abstract
We report a quantum dynamics study of the Li + HF → LiF + H reaction at low temperatures of interest to cooling and trapping experiments. Contributions from non-zero partial waves are analyzed and results show narrow resonances in the energy dependence of the cross section that survive partial wave summation. The computations are performed using the ABC code and a simple modification of the ABC code that enables separate energy cutoffs for the reactant and product rovibrational energy levels is found to dramatically reduce the basis set size and computational expense. Results obtained using two ab initio electronic potential energy surfaces for the LiHF system show strong sensitivity to the choice of the potential. In particular, small differences in the barrier heights of the two potential surfaces are found to dramatically influence the reaction cross sections at low energies. Comparison with recent measurements of the reaction cross section (Bobbenkamp et al 2011 J. Chem. Phys.
135 204306) shows similar energy dependence in the threshold regime and an overall good agreement with experimental data compared to previous theoretical results. Also, usefulness of a recently introduced method for ultracold reactions that employ the quantum close-coupling method at short-range and the multichannel quantum defect theory at long-range, is demonstrated in accurately evaluating product state-resolved cross sections for D + H2 and H + D2 reactions.

Published: May 2015

Abstract
Background.  The Xpert Mycobacterium tuberculosis (MTB)/rifampicin (RIF) is a fully automated diagnostic test that allows for the detection of MTB including its RIF resistance. Although the test is used for the diagnosis of tuberculosis (TB) in sputum samples worldwide, studies using fecal specimens are scarce. We therefore evaluated the efficacy of the Xpert MTB/RIF test for detection of MTB in fecal specimens obtained from adult pulmonary TB patients, confirmed by culture and/or molecular diagnostic methods.
Methods.  We conducted a retrospective case-control study to provide proof-of-concept regarding the efficacy of the Xpert MTB/RIF test using fecal samples for diagnosing pulmonary TB via detection of MTB in adult patients (≥20 years) at the Fukujuji Hospital in Tokyo, Japan.
Results.  Fecal specimens were obtained from 56 active pulmonary TB patients (including 48 sputum smear-positive and 8 sputum smear-negative patients), 10 non-TB patients (including 4 Myocobacterium avium complex infections), and 27 healthy individuals who were exposed to active pulmonary TB patients. The sensitivity of the fecal Xpert MTB/RIF was 100% (81.7%–100%) for detection of MTB in specimens from sputum smear-positive (1+ to 3+) patients, 81.0% (58.1%–94.6%) in specimens from sputum smear scanty positive patients, and 50.0% (15.7%–84.3%) in specimens from sputum smear-negative patients. Meanwhile, each of the fecal specimens from the non-TB group was negative for MTB (specificity 100%; 95% confidence interval, 86.2–100).
Conclusions.  The fecal Xpert MTB/RIF test could detect MTB in a large proportion of smear-positive pulmonary TB patients, without frequent false-positive results at a TB referral hospital in Japan.

Purpose:
We report clinical outcomes in patients treated with neoadjuvant endocrine therapy (NET) versus neoadjuvant cytotoxic chemotherapy (NCT) in a cohort of postmenopausal women with ER+, HER2− breast cancer.

Materials and Methods:
We retrospectively reviewed 140 patients treated between May 1998 and September 2010 and collected patient, disease, and treatment characteristics, response to neoadjuvant therapy, and clinical outcome.

Results:
The median age was 59.5 years. Stage group: stage I 2.2%, stage II 26.8%, stage III 71%, the median tumor size 6 cm (range, 1.5 to 19 cm). Fifty-seven (40.7%) received NET and 83 (59.3%) NCT. One patient (1.8%) in the NET group and 7 (8.4%) in the NCT group had a pathologic complete response (P=0.142). The median follow-up was 48.1 months. Five-year cumulative incidence of locoregional recurrence (LRR) among the entire cohort was 4.1% (95% confidence interval [CI]: 1.5, 8.9), and any recurrence 25.3% (95% CI: 17.6, 33.6). There was no difference in cumulative incidence of LRR or overall recurrence between NET and NCT. On multivariate analysis adjusting for receipt of chemotherapy, presenting stage, and positive lymph nodes, the use of adjuvant radiation therapy was associated with decreased risk of LRR (hazard ratio [HR]=0.24, P=0.035), and ypN2 status with higher risk of LRR (HR=4.91, P=0.032). When the same multivariate model was fitted for any recurrence outcome, only ypN2 status was a significant predictor of overall recurrence (HR=3.02, P=0.005).

Conclusions:
We have demonstrated equivalent locoregional and overall outcomes in patients receiving NET versus NCT in a cohort of postmenopausal women with locally advanced ER+HER2−tumors.

ABSTRACTObjectives:A large retrospective multicentre study was conducted in Spain to evaluate the efficiency of the new European Society for Pediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) criteria for the diagnosis of coeliac disease (CD).Methods:The study protocol was approved by the ethics committee of Hospital Universitari i Politècnic La Fe (Valencia, Spain). The present study included 2177 children (ages 0.6–15.9 years) with small bowel biopsy (SBB) performed for diagnostic purposes (from 2000 to 2009) and with a minimum 2‐year follow‐up after biopsy.Results:CD was diagnosed in 2126 patients (97.5%) and excluded in 51 (2.5%). Tissue transglutaminase antibodies (TG2A), anti‐endomysial antibodies (EMA), and human leukocyte antigen (HLA) were reported in 751 patients, 640 symptomatic and 111 asymptomatic. TG2A levels >10 times the upper limit of normal, plus positive EMA and HLA DQ2 and/or DQ8 haplotypes, were found in 336 symptomatic patients, all of them with final diagnosis of CD. In 65 of 69 asymptomatic patients, 65 had confirmed CD and 4 did not have CD. According to the 2012 ESPGHAN guidelines, SBB may have been omitted in 52% of the symptomatic patients with CD with serologic and HLA available data. Gluten challenge was performed in 158 children, 75 of them <2 years at first biopsy. Only 1 patient in whom according to the new proposed diagnostic criteria gluten challenge would not have been mandatory did not relapse.Conclusions:Our results support the new ESPGHAN 2012 guidelines for diagnosis of CD can be safely used without the risk of overdiagnosis. A prospective multicentre study is needed to confirm our results.
