Protocol for meta-analysis of temperature reduction in animal models of cardiac arrest

Targeted temperature management (TTM) of 32-34 °C has been the standard treatment for out-of-hospital cardiac arrest since clinical trials in 2002 showed benefits to survival and neurological outcome. Recently, this treatment has been challenged by another clinical trial showing no difference in outcome between TTM of 33 °C and 36 °C. This protocol describes the methodology for a meta-analysis det

Effect of alteplase on the CT hyperdense artery sign and outcome after ischemic stroke

OBJECTIVE: To investigate whether the location and extent of the CT hyperdense artery sign (HAS) at presentation affects response to IV alteplase in the randomized controlled Third International Stroke Trial (IST-3).METHODS: All prerandomization and follow-up (24-48 hours) CT brain scans in IST-3 were assessed for HAS presence, location, and extent by masked raters. We assessed whether HAS grew, p

Denial outperforms apology in repairing organizational trust despite strong evidence of guilt

Previous work in the areas of organizational trust repair and crisis communication has provided conflicting answers to the question of whether denial can be more effective than apology in repairing stakeholder trust in a company following an integrity-based violation. This article reportsthe results of an experiment designed to (i) test the effects of these two strategies on individuals’ trust in

Evaluation of δ13C in Carbonaceous Aerosol Source Apportionment at a Rural Measurement Site

The stable isotope of carbon, 13C, has been used in several studies for source characterization of carbonaceous aerosol since there are specific signatures for different sources. In rural areas, the influence of different sources is complex and the application of δ13C for source characterization of the total carbonaceous aerosol (TC) can therefore be difficult, especially the separation between bi

The European Social Dialogue in Perspective : Its future potential as an autopoietic system and lessons from the global maritime system of industrial relations

Denna avhandling har tre utgångspunkter. Den första är den europeiska sociala dialogen (ESD), vilken har kritiserats för att sakna kapacitet för att förbättra arbetsvillkor i EU. Den andra är det globala systemet för kollektivavtal och förhandlingar som har utvecklats genom ITFs kampanj mot bekvämlighetsflagg (ITF FOC), vilket anses ha kapacitet att förbättra villkor för sjömän på global nivå. DenThere are three starting points for this thesis. First, there is the system of ESD, which is criticised for lacking capacity to improve the working conditions within the EU. Secondly, there is the system developed through the global ITF FOC campaign, which is considered to have capacity to improve working conditions for seafarers at a global level. Thirdly, there is the theory on self-referential

Head computed tomography for prognostication of poor outcome in comatose patients after cardiac arrest and targeted temperature management

INTRODUCTION: A multimodal approach to prognostication of outcome after cardiac arrest (CA) is recommended. Evidence for combinations of methods is low. In this post-hoc analysis we described findings on head computed tomography (CT) after CA. We also examined whether generalised oedema on CT alone or together with the biomarker Neuron-specific enolase (NSE) could predict poor outcome.METHODS: Pat

Validity of the IQCODE-CA : An informant questionnaire on cognitive decline modified for a cardiac arrest population

AIM: To examine the psychometric properties of a modified version of the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE), for a cardiac arrest population (IQCODE-CA).METHODS: The IQCODE-CA, a 26-item observer-reported questionnaire, was completed by informants, defined as relatives or close friends, of 268 out-of-hospital cardiac arrest (OHCA) survivors who participated in the

Cerebral hypoperfusion is not associated with an increase in amyloid β pathology in middle-aged or elderly people

INTRODUCTION: It is hypothesized that cerebral hypoperfusion promotes the development of Alzheimer pathology. We therefore studied whether longstanding cerebral hypoperfusion is associated with Alzheimer pathology in nondemented humans.METHODS: Cerebral blood flow and amyloid β ((18)F-Flutemetamol) positron emission tomography retention were assessed in eleven patients with unilateral occlusion of

Centralization at Asine during the Bronze Age from a zooarchaeological perspective

From at least the Late Neolithic through the end of the Bronze Age and onwards, people continued to inhabit the settlement of Asine. For this reason, the site makes an interesting starting point for discussing long term change. This short paper presents new data on the animal bones from Bronze Age Asine. The data set is used for a zooarchaeological discussion of the site from a diachronic perspectFrom at least the Late Neolithic through the end of the Bronze Age and onwards, people continued to inhabit the settlement of Asine.

Opinion Polls, Coalition Signals and Strategic Voting. : Evidence from a survey experiment

Recent studies find that defection from one's most preferred party to some other party is as common under proportional representation (PR) as it is in plurality systems. It is less elaborated how election-specific contextual factors affect strategic vote choice under PR. This study looks at the impact of two potentially important contextual factors: parties’ coalition signals about cooperation wit

On cross‐linguistic variation and measures of linguistic complexity in learner texts: Italian, French and English

The paper investigates possible effects of cross-linguistic variation on measures of syntactic complexity in 60 texts from learners of L2 English, L3 French and L4 Italian at CEFR level A and CEFR level B. A previous study by Gyllstad et al. (2014) showed significant differences between proficiency levels for two length measures of complexity in English and French, but not in Italian. In this papeThe paper investigates possible effects of cross‐linguistic variation on measures of syntactic complexity in 60 texts from Swedish L1 learners of English, French and Italian as foreign languages at CEFR level A and CEFR level B. A previous study on the same learners and texts, showed significant differences between proficiency levels for two length measures of complexity in English and French, but

Go with the flow : visually mediated flight control in bumblebees

För ungefär 350 miljoner år sedan utvecklade de första insekterna förmågan att flyga och har sedan dess dominerat våra terrestra miljöer. Trots sina pyttesmå hjärnor och avsaknad av avancerade kontrollinstrument så lyckas flygande insekter på många vis utkonkurrera modern flygteknik. Humlor och bin kan till exempel leta upp en födokälla långt ifrån sitt bo, återvända hem igen och sedan upprepa denDespite their small brains and tiny eyes, flying insects are capable of detecting and avoiding collisions with moving obstacles, and with remarkable precision they navigate through environments of different complexity. For this thesis, I have investigated how bumblebees use the pattern of apparent image motion that is generated in their eyes as they move through the world (known as optic flow), in

Bridging the floods - The role of social learning for resilience building in urban water services

The development of cities is increasingly threatened by a worldwide water crisis. Urban water services (including drinking water, sanitation and drainage) are facing complex and multiple pressures, which are becoming increasingly frequent and severe. These pressures include floods, and the depletion, pollution and degradation of water resources and their associated ecosystems. These diverse pressu

Heterozygous Vangl2Looptail mice reveal novel roles for the planar cell polarity pathway in adult lung homeostasis and repair

Lung diseases impose a huge economic and health burden worldwide. A key aspect of several adult lung diseases, such as idiopathic pulmonary fibrosis (IPF) and chronic obstructive pulmonary disease (COPD), including emphysema, is aberrant tissue repair, which leads to an accumulation of damage and impaired respiratory function. Currently, there are few effective treatments available for these disea

Noncanonical WNT-5A signaling impairs endogenous lung repair in COPD

Chronic obstructive pulmonary disease (COPD) is a leading cause of death worldwide. One main pathological feature of COPD is the loss of functional alveolar tissue without adequate repair (emphysema), yet the underlying mechanisms are poorly defined. Reduced WNT-β-catenin signaling is linked to impaired lung repair in COPD; however, the factors responsible for attenuating this pathway remain to be
