Distribution of Vibrio vulnificus and Other Lactose-Fermenting Vibrios in the Marine Environment

During the summer of 1981, 3,887 sucrose-negative vibrios were isolated from seawater, sediment, plankton, and animal samples taken from 80 sites from Miami, Fla. , to Portland, Maine. Of these, 4.2% were able to ferment lactose. The lactose-positive strains isolated from the various samples correlated positively with pH and turbidity of the water, vibrios in the sediment and oysters, and total bacterial counts in oysters. Negative correlations were obtained for water salinity. Numerical taxonomy was performed on 95 of the lactose-fermenting environmental isolates and 23 reference strains. Five clusters resulted, with the major cluster containing 33 of the environmental isolates and all of the Vibrio vulnificus reference strains. The 33 isolates, which produced an acid reaction in lactose broth within hours of initial inoculation, represented 20% of all lactose-fermenting vibrios studied. These isolates were nearly identical phenotypically to clinical strains of V. vulnificus studied by the Centers for Disease Control, Atlanta, Ga. , and by our laboratory, and their identification was confirmed by DNA-DNA hybridization studies. V. vulnificus was isolated from all sample types and from Miami to Cape Cod, Mass. , and comparison of the environmental parameters of the eight subsites yielding this species with those of all 80 subsites revealed no significant differences. The majority of the isolates were obtained from animals, with clams providing most (84%) of these. On injection into mice, 82% of the V. vulnificus isolates resulted in death. Members of the remaining four clusters contained strains which differed from V. vulnificus in such phenotypic traits as luminescence and in urease or H2S production. None of the other reference cultures, including nine other Vibrio species, were contained in the remaining clusters, and these isolates could not be identified. Most of these were also lethal for mice. Phenotypic differences, potential pathogenicity, and geographic distribution of the five clusters were examined. It is concluded that V. vulnificus is a ubiquitous organism, both geographically and in a variety of environmental sources, although it occurs in relatively low numbers. The public health significance of this organism and of the other unidentified lactose-fermenting Vibrio species is discussed.
Susceptibilities of transparent, opaque, and rough colonial variants of Mycobacterium avium complex to various fatty acids

Three different colonial variants of Mycobacterium avium complex were studied for their susceptibilities to capric, lauric, oleic, and linolenic acids. Smooth T variants with transparent and irregularly shaped colonies were much more resistant to all the fatty acids than were the smooth D variants with opaque and dome-shaped colonies. Rough variants with granular and irregularly shaped colonies showed nearly the same susceptibility to the fatty acids as did the smooth T variants.
Factors Influencing the Development and Maintenance of Nocturnal Heavy-Rain-Producing Convective Systems in a Storm-Scale Ensemble

AbstractFrom 9 to 11 June 2010, a mesoscale convective vortex (MCV) was associated with several periods of heavy rainfall that led to flash flooding. During the overnight hours, mesoscale convective systems (MCSs) developed that moved slowly and produced heavy rainfall over small areas in south-central Texas on 9 June, north Texas on 10 June, and western Arkansas on 11 June. In this study, forecasts of this event from the Center for the Analysis and Prediction of Storms' Storm-Scale Ensemble Forecast system are examined. This ensemble, with 26 members at 4-km horizontal grid spacing, included a few members that very accurately predicted the development, maintenance, and evolution of the heavy-rain-producing MCSs, along with a majority of members that had substantial errors in their precipitation forecasts. The processes favorable for the initiation, organization, and maintenance of these heavy-rain-producing MCSs are diagnosed by comparing ensemble members with accurate and inaccurate forecasts. Even with.
Effect of Exchange-Coupling on Switching Fields in Magnetic Recording

Increased levels of exchange in a thin-film granular perpendicular recording media generally lead to reduced coercivity. However, this behavior cannot be deduced simply from the mean-field theory. To gain some insights into this behavior, a simple 2-D chain-of-grains model is employed. It can be recognized that the reduction in coercivity is due to the presence of in-plane magnetization and the corresponding in-plane fields that arise at the transitions between magnetized regions. In addition, a comparison is made between the two classical forms for exchange energy, 1-cosθ and 1/2θ2, that link adjacent grains. The latter form is found to have a much larger impact on coercivity and results in a more Kondorsky-like angular dependence.

A robust state observer scheme

This note proposes a new approach to robust state observer construction. The scheme is derived by including an extra term and adopting the Lyapunov stability theorem, and requires the solution of an algebraic Riccati equation. The scheme is implemented in a gas-fired furnace system example. Satisfactory results have been obtained, though in general special attention need be paid to some numerical issues in implementing the scheme.
Do We Ruin the Moment? Exploring the Design of Novel Capturing Technologies

By capturing our experiences we often strive to better remember them in the future. However, the act of media capturing also influences these same experiences in the present, an area which is underexplored. This paper describes a study with the aim to inform the design of novel media capturing strategies. Adopting an approach of defamiliarization based on intervention and reflection, we strive to gain insights in the influences of future capturing technologies on the experience of a day out. We conducted an exploratory study in which 28 students went on a day out and used a variety of capturing strategies. Individual and group reflections on the experience during this day identified several important aspects that media capturing influences: engagement, perception & attention and social activity. The paper concludes with implications for design and proposes three potential future directions for media capturing, that instead of disturbing the moment enhance the experience.
Single-Dose, Sustained-Release Epidural Morphine in the Management of Postoperative Pain After Elective Cesarean Delivery: Results of a Multicenter Randomized Controlled Study

In this multicenter, randomized, controlled study, we compared the analgesic efficacy and safety profile of a new single-dose extended-release epidural morphine (EREM) formulation (DepoDur™) with that of epidural morphine sulfate for the management of postoperative pain for up to 48 h after elective cesarean delivery. ASA physical status I or II parturients (n = 75) were anesthetized with a combined spinal/epidural technique. Parturients received intrathecal bupivacaine 12–15 mg and fentanyl 10 &mgr;g for spinal anesthesia and a single epidural injection of either 5 mg of standard (conventional preservative-free) morphine or 5, 10, or 15 mg of extended-release morphine after cord clamping for postoperative pain control. Single-dose EREM 10 and 15 mg groups significantly decreased total supplemental opioid medication use and improved functional ability scores for 48 h after surgery compared with those receiving 5 mg of standard morphine. Visual analog scale pain scores at rest and with activity at 24 to 48 h after dosing were significantly better in the 10- and 15-mg single-dose EREM groups versus the standard morphine group. There were no significant differences between the two 5 mg (single-dose EREM and standard morphine) groups. Single-dose EREM was well tolerated, and most adverse events were mild to moderate in severity. Single-dose EREM is a potentially beneficial epidural analgesic for the management of post-cesarean delivery pain and has particular advantages over standard morphine for the period from 24 to 48 h after surgery.
The pathology of liver allograft surving longer than one year

Although prolonged survival after liver transplantation is now common, the condition of allografts after prolonged survival has not been widely discussed. We reviewed 86 biopsy samples from 38 patients. The samples were obtained between 366 and 1,622 days after transplant. Thirteen patients' biopsy samples were normal or showed minor changes. Six patients' samples showed rejection. Four patients, including two with rejection, demonstrated ischemic change. Three patients showed focal fibrosis, polymorphonuclear infiltration and bile duct proliferation simulating biliary obstruction, although biliary stones were found in only one patient. Three patients had acute hepatitis. Seven patients had a pattern of chronic persistent hepatitis; four had chronic active hepatitis. Follow‐up biopsy samples were obtained in seven chronic hepatitis patients. Two of the patients with chronic active hepatitis have shown slight progression of the disease. None has progressed to cirrhosis, but neither has the chronic active hepatitis resolved. It is likely that some of these cases represent non‐A, non‐B hepatitis. Although histological abnormalities are common after successful transplantation, the clinical significance of many of the changes remains to be determined. Only patients with rejection or vascular thromboses required new transplants. (HEPATOLOGY 1990;11:465–470.)
Eine Managementlösung zur Integration CORBA-basierter Anwendungen in bestehende Managementplattformen

ZUSAMMENFASSUNG In den vergangenen Jahren sind Unternehmen in steigendem Maße abhängig geworden vom korrekten Funktionieren ihrer IT-gestützten Geschäftsprozesse. Die Implementierung dieser Geschäftsprozesse erfolgt in der Regel mit Hilfe mehrsträngiger Architekturen, bei denen CORBA eine bedeutende Rolle als integrierende Middleware einnimmt. Heutige Managementwerkzeuge abstrahieren von der Realisierungsart verteilter Anwendungen, d.h. das Gesamtsystem wird nur als Menge von Betriebssystemprozessen gesehen. Im Sinne eines proaktiven Managements, welches schleichende Fehler erkennen soll und einer möglichst präzisen Fehlerursachenbenennung ist eine solche Abstraktion nachteilig, da eine Reihe essentieller Informationsquellen ausgeschlossen werden. In einer Zusammenarbeit zwischen der Fachhochschule Wiesbaden und der Lufthansa Systems GmbH wurde eine Managementlösung entwickelt, die eine Integration von CORBA-basierten Anwendungen in bestehende Managementumgebungen ermöglicht. Der entwickelte Managementkern baut auf einer flexiblen Modularchitektur auf, die eine hohe Adaptierbarkeit an unterschiedliche Umgebungen garantiert. Weiterhin besitzt der Managementkern Mechanismen zur Sicherstellung einer hohen Verfügbarkeit, wie Selbstdiagnose und verschiedene Betriebsmodi. Zur Abfrage von Management-relevanten Informationen aus einer CORBA-basierten Anwendung wurde die generische Managementschnittstelle entwickelt, mit deren Hilfe CORBA-Anwendungen beobachtet und beeinflusst werden können. Innerhalb des Lufthansa Rechenzentrums fügt sich der Managementkern in die bestehende HP-IT/Operations-basierte Managementumgebung ein.
Demo: Dynamic Adaptations of WiFi Channel Widths Without TX/RX Coordination

Most modern standards for wireless communications support physical layer adaptations, in terms of dynamic selection of channel central frequency, transmission power, modulation format, etc., in order to increase link robustness under time-varying propagation and interference conditions. In this demo, we demonstrate that another powerful solution for extending physical layer flexibility in OFDM-based technologies is the dynamic adaptation of the channel width. Although some standards already define the possibility of utilizing multiple channel widths (e.g. 20MHz, 10MHz, 5MHz for IEEE 802.11a standards), such an utilization is limited to a static configuration of a value defined during the network set-up. Conversely, we demonstrate that channel width adaptations can be performed in real-time during network operation, even on a per-packet basis. To this purpose, we propose an innovative and efficient receiver design, which allows the transmitter to take decisions about the channel width without explicitly informing the receiver.
Post-operative radiotherapy for ductal carcinoma in situ of the breast.

BACKGROUND The addition of radiotherapy (RT) following breast conserving surgery (BCS) was first shown to reduce the risk of ipsilateral recurrence in the treatment of invasive breast cancer. Ductal carcinoma in situ (DCIS) is a pre-invasive lesion. Recurrence of ipsilateral disease following BCS can be either DCIS or invasive breast cancer. Randomised controlled trials (RCTs) have shown that RT can reduce the risk of recurrence, but assessment of potential long-term complications from addition of RT following BSC for DCIS has not been reported for women participating in RCTs. OBJECTIVES To summarise the data from RCTs testing the addition of RT to BCS for treatment of DCIS to determine the balance between the benefits and harms. SEARCH METHODS We searched the Cochrane Breast Cancer Group Specialised Register (2 June 2011), Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2008, Issue 1), MEDLINE (2 June 2011), EMBASE (2 June 2011) and the World Health Organization's International Clinical Trials Registry Platform (WHO ICTRP; 2 June 2011). Reference lists of articles and handsearching of ASCO (2007), ESMO (2002 to 2007), and St Gallen (2005 to 2007) conferences were performed. SELECTION CRITERIA RCTs of breast conserving surgery with and without radiotherapy in women at first diagnosis of pure ductal carcinoma in situ (no invasive disease present). DATA COLLECTION AND ANALYSIS Two authors independently assessed each potentially eligible trial for inclusion and its quality. Two authors also independently extracted data from published Kaplan-Meier analysis (survival curves) and reported summary statistics. Data were extracted and pooled for four trials. Data for planned subgroups were extracted and pooled for analysis.There were insufficient data to pool for long-term toxicity from radiotherapy. MAIN RESULTS Four RCTs involving 3925 women were identified and included in this review. All were high quality with minimal risk of bias. Three trials compared the addition of RT to BCS. One trial was a two by two factorial design comparing the use of RT and tamoxifen, each separately or together, in which participants were randomised in at least one arm. Analysis confirmed a statistically significant benefit from the addition of radiotherapy on all ipsilateral breast events (hazards ratio (HR) 0.49; 95% CI 0.41 to 0.58, P < 0.00001), ipsilateral invasive recurrence (HR 0.50; 95% CI 0.32 to 0.76, p=0.001) and ipsilateral DCIS recurrence (HR 0.61; 95% CI 0.39 to 0.95, P = 0.03). All the subgroups analysed benefited from addition of radiotherapy. No significant long-term toxicity from radiotherapy was found. No information about short-term toxicity from radiotherapy or quality of life data were reported. AUTHORS' CONCLUSIONS This review confirms the benefit of adding radiotherapy to breast conserving surgery for the treatment of all women diagnosed with DCIS. No long-term toxicity from use of radiotherapy was identified.
The German Version of the Behavioral Activation for Depression Scale (BADS): A Psychometric and Clinical Investigation.

UNLABELLED The Behavioral Activation for Depression Scale (BADS) was developed to measure core concepts of behavioural activation for depression. A number of studies, mostly based on analogue samples, have provided initial support for the BADS. In the present study, we examined the psychometric properties of the German version of the scale more broadly, including change sensitivity and clinical treatment data. A mixed sample of students (N = 312) and depressed outpatients in partial remission undergoing cognitive-behavioural group treatment for depressive rumination (N = 59) was examined. To analyze construct validity, a set of theoretically relevant constructs such as perseverative thinking, distraction and mindfulness was also assessed. Results indicated good psychometric properties, additional evidence for construct validity of the total scale and subscales, and adequate fit of the data to the original factor structure. Furthermore, the BADS proved to be sensitive to changes in participants undergoing treatment for depression. Copyright © 2015 John Wiley & Sons, Ltd. KEY PRACTITIONER MESSAGE Behavioural activation (BA) is an effective treatment for patients suffering from unipolar depression. The Behavioral Activation for Depression Scale (BADS) can be used to measure core elements of the BA treatment rationale. It is useful to track changes in activation within treatment. The BADS is available in different languages and has shown to possess good psychometric properties.
Predictive Controller for Fourth Order Buck Topologies

In this paper, an approach for the design of predictive controller for fourth order buck topologies is proposed. The controller is designed to achieve the load voltage regulation against load and source disturbances. A zero ripple technique is used to reduce the ripple in inductor current. The dynamic characteristics of the coupled fourth order buck converter are compared with the uncoupled converter. Simulation results show that coupled converter gives the better performance in terms of ripple reduction and load voltage regulation
General screening procedure for RNA modificationless mutants: isolation of Escherichia coli strains with specific defects in RNA methylation

A general method for the isolation of mutants of Escherichia coli that are defective in RNA modification is described. The method is based on the fact that RNA with specific undermodifications accumulates under nonpermissive growth conditions and that such a defect can be detected by remodification either in vivo at permissive conditions or in vitro. The method provides a means by which to study mutations affecting essential modification reactions. The usefulness of the method was demonstrated by the isolation of two rRNA and two tRNA methylation defective mutants. Both rRNA mutants accept methyl groups into their 23S rRNA in vitro. Analyses of in vitro methylated 23S rRNA from one of the mutants revealed the presence of several methylated nucleosides, of which 6-methyladenosine was the most abundant (40% of recovered radioactivity). In 23S rRNA from the other mutant, the only product formed in vitro was 5-methylcytidine. The tRNA mutants are characterized in the accompanying paper.
Exfoliative cytology as a tool for monitoring pre-malignant and malignant lesions based on combined stains and morphometry techniques.

BACKGROUND Prevention and early diagnosis have the greatest potential for public health and are the most effective method in the long-term to control oral cancer. The aim was to apply PAP staining together with AgNOR staining and morphometric analysis in oral exfoliative cytology, to determine the sensitivity and specificity of these methods in the detection of malignant changes for the purposes of both initial population monitoring and follow-up. METHODS AgNOR, Papanicolau, and morphometric tests were conducted in samples of patients with oral cancer, oral potentially malignant disorders and controls (opposite side of lesions). Specificity and sensitivity values for each stain method and the curve under ROC area were estimated. RESULTS The diagnostic variables which allowed greatest accuracy in identifying malignancy relative to the healthy control were cluster (76.92%), satellite (75.64%), and total (90%). The diagnosis was seen to be associated with PAP and total AgNOR, total AgNOR and PAP, total AgNOR and satellites and clusters, and total AgNOR nuclear area/cytoplasmic area ratio. CONCLUSIONS The total number of AgNOR is a reliable marker for detecting neoplastic cells; this method increases sensitivity and specificity by decreasing the likelihood of false negatives or positives, as the accuracy obtained was 90%. It is also a low-cost, non-invasive, simple methodology that can be recommended to help the early detection of oral cancer and monitoring of patients with a first diagnosis of cancer.
Design of 8mm Ka-band broadband LNA

The HEMT model in this article is applied by OMMIC D01PH. In this article we design a five circuit, the first two levels are designed for minimum noise and the last three for maximum gain design. The center frequency of this design is 35 GHz with 6 GHz bandwidth, gain is greater than 30dB and the noise figure is less than 3dB. This article describes a Ka-band low-noise amplifier design idea. In this idea we put up two options for the bias circuit design, one is drain supply by a single power and the other is dual-power supply for the drain and gate. We make circuit design and simulation for each program and the simulation results were analyzed and compared.
Suicide attempts and self-mutilative behavior in a juvenile correctional facility.

OBJECTIVE To determine the lifetime history of suicide attempts in incarcerated youths and psychological factors related to suicidal and self-mutilative behaviors during incarceration. METHOD A 25% systematic random sample chart review of adolescents admitted to a juvenile correctional facility yielded a sample of 289 adolescents. Seventy-eight of these adolescents were clinically referred for psychiatric assessment. Suicidal behavior was assessed with the Spectrum of Suicidal Behavior Scale and self-mutilation with the Functional Assessment of Self-Mutilation. RESULTS Of the 289 adolescents, 12.4% reported a prior suicide attempt. Almost 60% of these attempts were made using violent methods (e.g., cutting). Of the 78 clinically referred subjects, 30% reported suicidal ideation/behavior and 30% reported self-mutilative behavior while incarcerated. Suicidal clinically referred adolescents reported more depression, anxiety, and anger than nonsuicidal youths. Adolescents who reported self-mutilative behavior had higher anxiety, anger, and substance use than non-self-mutilative adolescents. CONCLUSIONS Results suggest that incarcerated adolescents have higher rates of suicide attempts and use more violent methods of attempt than adolescents in the general population. Furthermore, incarcerated clinically referred suicidal and self-mutilative youths report more severe affective symptoms than their nonsuicidal and non-self-mutilative counterparts, suggesting a need for mental health treatment.
Current perspectives in digital speech

THE field of digital speech is rapidly coming to fruition as an area of opportunity for commercial application. In this paper we attempt to give a broad tutorial overview of some of the key aspects of this technology. We briefly outline some of the basic properties of speech and the techniques of coding that use these properties and point to areas of current research and areas of practical hardware implementation. We also attempt to outline some of the potential application areas for this new technology.
