Barbiturates are used clinically as anaesthetics and to reduce raised intracranial pressure. One side effect is hypotension, usually ascribed to a depression of cardiac contractility, while their effects on the resistance vessels are more controversial: both vasodilation and vasoconstriction have been described. This study analyzes the effects of thiopental on basal vascular tone in the cat skelet
The introduction of picture and archiving communicating systems is currently being evaluated in several institutions. We decided, as an intermediate step, to see if image quality after transferral to a personal computer (PC) is sufficient for the diagnostic needs in an intensive care unit. Seventy-five portable digital chest radiographs were studied both as hard-copies and on a monitor after trans
The international standard ISO 22400 has defined a set of Key Performance Indicators (KPIs) to evaluate the performance of manufacturing operation. However, the defined KPIs seem to be inspired from the discrete production context, and hence do not automatically fit the process industry context. The process industry is defined as the industry in which the raw material undergoes conversion during a
BACKGROUND: Inhaled nitric oxide may be useful in the treatment of pulmonary hypertension and hypoxaemia. Nitric oxide is rapidly oxidized to nitrogen dioxide, which is toxic and may adversely affect the airways of the patient. The aim of the present investigation was to examine factors that may affect the concentration of nitrogen dioxide, using the Servo Ventilator 300 nitric oxide delivery syst
We have evaluated the kinetics of nitrogen dioxide production in a system for inhalation of nitric oxide. In addition to a small fraction of contamination of nitrogen dioxide in the nitric oxide stock gas, a considerable part of the total concentration of nitrogen dioxide is formed immediately after mixing of nitric oxide and oxygen. This initial build-up of nitrogen dioxide is followed by a linea
We have analysed the ability of three nitrogen dioxide absorbing materials (soda lime, noXon and zeolite) to act as nitrogen dioxide scavengers during delivery of inhaled nitric oxide. Different mixtures of gas were produced in a ventilator (Servo Ventilator 300) and passed through an inspiratory tube. Concentrations of nitrogen dioxide and nitric oxide were measured in the distal part of the tube
BACKGROUND: The release of neuron-specific astroglial S-100 protein to the cerebrospinal fluid is a marker of cerebral damage. The aim of this study was to determine the pattern of release of S-100 protein to serum after pediatric cardiac operations and extracorporeal circulation.METHODS: Sequential blood samples from 97 children (up to 16 years) were taken after induction of anesthesia, immediate
Aims Carotid intima media thickness (CIMT) predicts cardiovascular (CVD) events, but the predictive value of CIMT change is debated. We assessed the relation between CIMT change and events in individuals at high cardiovascular risk. Methods and results From 31 cohorts with two CIMT scans (total n = 89070) on average 3.6 years apart and clinical follow-up, subcohorts were drawn: (A) individuals wit
Characterization of land cover change in the past is fundamental to understand the evolution and present state of the Earth system, the amount of carbon and nutrient stocks in terrestrial ecosystems, and the role played by land-atmosphere interactions in influencing climate. The estimation of land cover changes using palynology is a mature field, as thousands of sites in Europe have been investiga
Increasing climate change impacts are a major threat to sustainable urban development, and challenge current governance structures, including actors' responsibilities for dealing with climate variability and extremes. The need for distributed risk governance and citizen engagement is increasingly recognised; however, few empirical studies systematically assess interactions between citizens and mun
Background: Heart failure is a disease with high morbidity, mortality, and physical and psychological burden. More knowledge about the care provided for patients with heart failure close to death is needed. Objective: The aim was to describe key aspects of palliative care during the last week of life in patients with heart failure, as reported by healthcare professionals. Design: This is a nationa
Substantial progress has been achieved in the last couple of decades in computing the electronic structure of correlated materials from first principles. This progress has been driven by parallel development in theory and numerical algorithms. Theoretical development in combining ab initio approaches and many-body methods is particularly promising. A crucial role is also played by a systematic met
Through the social-historical contextualization of Gezi protests and drawing on the works of Badiou and Turner this article conceptualises the protests as a ‘happening’ or ‘event’ characterized by rupture and liminality. Without underestimating their importance as a meaning creation process, it is argued that the visions inspiring Gezi have been/are in sharp contrast to the version of democracy sh
Low-quality health services are a problem across low- and middle-income countries. Information failure may contribute, as patients may have insufficient knowledge to discern the quality of health services. That decreases the likelihood that patients will sort into higher quality facilities, increasing demand for better health services. This paper presents results from a health survey in Nigeria to
A search for heavy resonances decaying into a pair of Z bosons leading to ℓ+ℓ-ℓ+ℓ- and ℓ+ℓ- final states, where ℓ stands for either an electron or a muon, is presented. The search uses proton–proton collision data at a centre-of-mass energy of 13 TeV corresponding to an integrated luminosity of 36.1 fb - 1 collected with the ATLAS detector during 2015 and 2016 at the Large Hadron Collider. Differe
Background and Aims: To investigate the paraclinical and pathological features of surgically resected intraductal papillary mucinous neoplasms in Sweden. Materials and Methods: A review of prospectively collected data on patients undergoing pancreatic resection for a histopathologically verified intraductal papillary mucinous neoplasm between 2010 and 2016 was performed using the Swedish National
Exposure to cadmium confers increased cardiovascular risk. Tobacco smoke contains cadmium, which, hypothetically, may mediate parts of the tobacco-associated risk of developing atherosclerotic plaques. Baseline data from the Swedish Malmö Diet and Cancer cohort (1991-1996) were used to test this hypothesis. Mediation analysis was used to examine associations between smoking and blood cadmium level
