Impact of biocontrol strain Pseudomonas fluorescens CHA0 on rhizosphere bacteria isolated from barley (Hordeum vulgare L.) with special reference to Cytophaga-like bacteria.

AIMS: To assess the impact of the biocontrol strain Pseudomonas fluorescens CHA0 on a collection of barley rhizosphere bacteria using an agar plate inhibition assay and a plant microcosm, focusing on a CHA0-sensitive member of the Cytophaga-like bacteria (CLB). METHODS AND RESULTS: The effect of strain CHA0 on a collection of barley rhizosphere bacteria, in particular CLB and fluorescent pseudomonads sampled during a growth season, was assessed by a growth inhibition assay. On average, 85% of the bacteria were sensitive in the May sample, while the effect was reduced to around 68% in the July and August samples. In the May sample, around 95% of the CLB and around 45% of the fluorescent pseudomonads were sensitive to strain CHA0. The proportion of CHA0-sensitive CLB and fluorescent pseudomonad isolates decreased during the plant growth season, i.e. in the July and August samples. A particularly sensitive CLB isolate, CLB23, was selected, exposed to strain CHA0 (wild type) and its genetically modified derivatives in the rhizosphere of barley grown in gnotobiotic soil microcosms. Two dry-stress periods were imposed during the experiment. Derivatives of strain CHA0 included antibiotic or exopolysaccharide (EPS) overproducing strains and a dry-stress-sensitive mutant. Despite their inhibitory activity against CLB23 in vitro, neither wild-type strain CHA0, nor any of its derivatives, had a major effect on culturable and total cell numbers of CLB23 during the 23-day microcosm experiment. Populations of all inoculants declined during the two dry-stress periods, with soil water contents below 5% and plants reaching the wilting point, but they recovered after re-wetting the soil. Survival of the dry-stress-sensitive mutant of CHA0 was most affected by the dry periods; however, this did not result in an increased population density of CLB23. CONCLUSIONS: CLB comprise a large fraction of barley rhizosphere bacteria that are sensitive to the biocontrol pseudomonad CHA0 in vitro. However, in plant microcosm experiments with varying soil humidity conditions, CHA0 or its derivatives had no major impact on the survival of the highly sensitive CLB strain, CLB23, during two dry-stress periods and a re-wetting period; all co-existed well in the rhizosphere of barley plants. SIGNIFICANCE AND IMPACT OF THE STUDY: Results indicate a lack of interaction between the biocontrol pseudomonad CHA0 and a sensitive CLB when the complexity increases from agar plate assays to plant microcosm experiments. This suggests the occurrence of low levels of antibiotic production and/or that the two bacterial genera occupy different niches in the rhizosphere.

Stroke initial severity and outcome relative to insurance status in a universal health care system in Switzerland.

BACKGROUND:  Socioeconomic status is thought to have a significant influence on stroke incidence, risk factors and outcome. Its influence on acute stroke severity, stroke mechanisms, and acute recanalisation treatment is less known. METHODS:  Over a 4-year period, all ischaemic stroke patients admitted within 24 h were entered prospectively in a stroke registry. Data included insurance status, demographics, risk factors, time to hospital arrival, initial stroke severity (NIHSS), etiology, use of acute treatments, short-term outcome (modified Rankin Scale, mRS). Private insured patients (PI) were compared with basic insured patients (BI). RESULTS:  Of 1062 consecutive acute ischaemic stroke patients, 203 had PI and 859 had BI. They were 585 men and 477 women. Both populations were similar in age, cardiovascular risk factors and preventive medications. The onset to admission time, thrombolysis rate, and stroke etiology according to TOAST classification were not different between PI and BI. Mean NIHSS at admission was significantly higher for BI. Good outcome (mRS ≤ 2) at 7 days and 3 months was more frequent in PI than in BI. CONCLUSION:  We found better outcome and lesser stroke severity on admission in patients with higher socioeconomic status in an acute stroke population. The reason for milder strokes in patients with better socioeconomic status in a universal health care system needs to be explained.

Status of Females in the Juvenile Justice System, 2007

On October 12th 2007, the inaugural Girls’ Summit on females in the juvenile justice system was held. This Summit brought together key decision makers in an exploration of research and data. Those who attended were also asked to make recommendations regarding a course of action. This report represents an effort to improve our response to these young women in Iowa. It highlights pertinent information covered at the Summit as well as resulting conclusions and recommendations. On behalf of the Iowa Gender Specific Services Task Force and the participants of the Girls’ Summit, it is my hope that this report will serve as a road map for necessary improvements as well as a means to reinforce the effective tools that are already in place. There are differences that exist between young women and young men in the juvenile justice system and the efficacy of professionals rests heavily on a better understanding of these differences and how they impact the justice system response.

Iowa Commission on the Status of Women: 35th Annual Report - 2006

Iowa Commission on the Status of Women: 35th Annual Report - 2006 The ICSW is proud of the past year’s achievements, and pleased to present to you our 35th Annual Report. The following pages detail the activities and programs that were carried out in 2006. The ICSW celebrates the progress in women’s rights that has been made in Iowa, and continues to address inequities, advocating for full participation by women in the economic, social, and political life of the state. In this advocacy role, as mandated by the Code of Iowa, we educate, inform, and develop new ideas to bring a fresh viewpoint to bear on the issues facing Iowa women and their families.

Status of Iowa Women Report, 2006

The Iowa Commission on the Status of Women (ICSW) is a state agency that seeks to assure equality for Iowa women. As an advocacy agency, the Commission works to equalize women's opportunities and to promote full participation by women in the economic, political, and social life of the state. This is the tenth edition of the Status of Iowa Women Report. Many positive changes toward women's full participation in all aspects of society are evident in this edition: more women than ever are getting a post-secondary education and they have made significant inroads into some traditionally male-dominated work domains. Still, much remains to be done. The 2006 report also shows that girls, by and large, are not enrolling in upper-level high-school computer courses, a necessity for the 21st century; women's earnings lag behind men's; and women continue to be raped, beaten, and battered at staggering rates. Much work needs to be done at the community and state levels to address those and other challenges addressed in this publication.

Esta dissertação analisa as principais características e as dificuldades que se levantam ao desenvolvimento de dois grupos de países em situações especiais, especificamente os PMA e os SIDS. Neste contexto, são abordadas questões relacionadas com medidas de apoio por parte da comunidade internacional, visando facilitar o processo de desenvolvimento dos PMA, e analisada a questão (por vezes controversa) da transição da lista de PMA. Neste quadro, é analisado o caso de Cabo Verde – o primeiro SIDS a transitar da lista de PMA –, com a consideração prévia de importantes questões de financiamento do desenvolvimento, de suma importância para a capacidade do país suster o seu desenvolvimento, a partir da entrada em vigor da sua graduação da lista dos PMA, em Janeiro de 2008.

Rediscovery of the putatively extinct ant species Simopelta minima (Brandão) (Hymenoptera, Formicidae), with a discussion on rarity and conservation status of ant species

Simopelta minima (Brandão, 1989) was originally described based on four workers collected in soil samples from a small cocoa plantation in Ilhéus, state of Bahia, northeastern Brazil. In the subsequent years after the description, this cocoa plantation was eliminated and the species was then considered extinct by the Brazilian environmental institutions. The recent rediscovery of S. minima workers in subterranean pitfall trap samples from Viçosa, state of Minas Gerais, southeastern Brazil, over 1.000 km distant from type locality, suggests that the rarity and vulnerability status of some ant species may be explained by insufficient sampling of adequate microhabitats, in time and space.

Intravenous Lacosamide for Treatment of Status Epilepticus after Failing First-Line Therapy

Rationale: Treatment of status epilepticus (SE) usually requires intravenous anticonvulsant therapy. Although there are established drugs of first choice for its treatment, potentially hazardous side effects of these agents are not uncommon. Lacosamide (LCM) is a novel anticonvulsant drug that is available as infusion solution. LCM could be an alternative for treatment of SE when the standard drugs fail or should be avoided. Methods: We retrospectively identified patients from the hospital databases of two German and one Swiss neurological departments (University Hospital Marburg, Klinikum Osnabrueck, University Hospital Lausanne) between September 1st 2008 and May 22nd 2009 who were admitted because of SE and received at least one dose of intravenous LCM for treatment of SE. Results: Seventeen patients (11 female, 6 male) were identified. Median age was 71 years. 3 patients suffered from generalized convulsive SE, 8 patients had significant reduction of awareness with or without subtle motor symptoms, 6 patients had a simple focal status without relevant reduction of awareness. Etiology was acute symptomatic in 5 patients, remote symptomatic without pre-existing epilepsy in 6 patients, remote symptomatic and pre-existing epilepsy in 5 patients, and unknown in 1 patient. LCM was administered after failure of first line therapy in all cases. The first LCM bolus was 400mg in 13 patients and 200mg in 4 patients. LCM administration stopped SE in 7 patients. In 2 of them, LCM was administered immediately after benzodiazepine administration, in the others after failure of benzodiazepines and other first-line and/or second-line drugs. In 3 patients, SE was terminated by other anticonvulsants like Phenytoin, Phenobarbital or Oxcarbazepine. In 5 patients, SE could only be terminated by intubation and application of high-dose Midazolam, Propofol and/or Thiopental. In 2 patients, SE could not be terminated in spite of high doses of barbiturates. There was no serious adverse event documented that could possibly be attributed to LCM Conclusions: Intravenous LCM may be an alternative treatment for SE after failure of benzodiazepins and other established drugs, or when such agents are considered unsuitable.

Ambiguity seeking as a result of the status quo bias

Several factors affect attitudes toward ambiguity. What happens, however, when peopleare asked to exchange an ambiguous alternative in their possession for an unambiguousone? We present three experiments in which individuals preferred to retain the former.This status quo bias emerged both within- and between-subjects, with and withoutincentives, with different outcome distributions, and with endowments determined byboth the experimenter and the participants themselves. Findings emphasize the need toaccount for the frames of reference under which evaluations of probabilistic informationtake place as well as modifications that should be incorporated into descriptive modelsof decision making.

Characterization of a new clinical yeast species, Candida tunisiensis sp. nov., isolated from a strain collection from Tunisian hospitals.

From a collection of yeast isolates isolated from patients in Tunisian hospitals between September 2006 and July 2010, the yeast strain JEY63 (CBS 12513), isolated from a 50-year-old male that suffered from oral thrush, could not be identified to the species level using conventional methods used in clinical laboratories. These methods include matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS), germ tube formation, and the use of CHROMagar Candida and metabolic galleries. Sequence analysis of the nuclear rRNA (18S rRNA, 5.8S rRNA, and 26S rRNA) and internal transcribed spacer regions (ITS1 and ITS2) indicated that the ribosomal DNA sequences of this species were not yet reported. Multiple gene phylogenic analyses suggested that this isolate clustered at the base of the Dipodascaceae (Saccharomycetales, Saccharomycetes, and Ascomycota). JEY63 was named Candida tunisiensis sp. nov. according to several phenotypic criteria and its geographical origin. C. tunisiensis was able to grow at 42°C and does not form chlamydospores and hyphae but could grow as yeast and pseudohyphal forms. C. tunisiensis exhibited most probably a haploid genome with an estimated size of 10 Mb on at least three chromosomes. Using European Committee for Antimicrobial Susceptibility Testing (EUCAST) and Clinical and Laboratory Standards Institute (CLSI) Candida albicans susceptibility breakpoints as a reference, C. tunisiensis was resistant to fluconazole (MIC = 8 μg/ml), voriconazole (MIC = 0.5 μg/ml), itraconazole (MIC = 16 μg/ml), and amphotericin B (MIC = 4 μg/ml) but still susceptible to posaconazole (MIC = 0.008 μg/ml) and caspofungin (MIC = 0.5 μg/ml). In conclusion, MALDI-TOF MS permitted the early selection of an unusual isolate, which was still unreported in molecular databases but could not be unambiguously classified based on phylogenetic approaches.
