Effects of calcium antagonists on myogenic and neurogenic control of resistance and capacitance vessels in cat skeletal muscle

The effects of five different calcium antagonists (diltiazem, felodipine, nifedipine, nimodipine, and verapamil) on cat skeletal muscle resistance and capacitance vessels were studied in a whole organ preparation. These calcium antagonists seemed to have the similar qualitative effects on these vascular functions. Calcium antagonists were found to be potent inhibitors of myogenic vascular reactivi

Impact of RF cables on the electromagnetic environment in vehicles

As the demand for connectivity and infotainment services increases in the automotive world, the need to measure and characterize the propagation channels inside vehicles also increases. In this work, a measurement study was performed to investigate the influence of RF cables on in-vehicle channels. It was found that, for the same transmit and receive antenna positions, the routing of the measureme

Effects of thiopental on resistance vessels in cat skeletal muscle

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

Bedside chest radiography using digital luminescence : A comparison between digital radiographs reviewed on a personal computer and as hard-copies

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

Key performance indicators for manufacturing operations management in the process industry

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

Production of nitrogen dioxide during nitric oxide therapy using the Servo Ventilator 300 during volume-controlled ventilation

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

Production of nitrogen dioxide in a delivery system for inhalation of nitric oxide : a new equation for calculation

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

Evaluation of nitrogen dioxide scavengers during delivery of inhaled nitric oxide

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

Serum S-100 protein levels after pediatric cardiac operations : a possible new marker for postperfusion cerebral injury

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

Predictive value for cardiovascular events of common carotid intima media thickness and its rate of change in individuals at high cardiovascular risk – Results from the PROG-IMT collaboration

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

European forest cover during the past 12,000 years : A palynological reconstruction based on modern analogs and remote sensing

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

Collaborative Governance for Climate Change Adaptation : Mapping citizen–municipality interactions

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

Symptom Relief and Palliative Care during the Last Week of Life among Patients with Heart Failure : A National Register Study

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

Recent progress in first-principles methods for computing the electronic structure of correlated materials

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

A momentary lapse of reason? Gezi in social-historical perspective

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

Health-care quality and information failure : Evidence from Nigeria

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

Search for heavy ZZ resonances in the ℓ+ℓ-ℓ+ℓ- and ℓ+ℓ- final states using proton–proton collisions at √s=13 TeV with the ATLAS detector

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.
