Objectives Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality. Iron deficiency, with or without anaemia, associated other chronic conditions, such as congestive heart failure, where it predicts worse outcome. However, the prevalence iron deficiency in COPD unknown. This observational study aimed to determine associations differences clinical phenotype. Setting University hospital outpatient clinic. Participants 113 adult patients (65% male) diagnosed...
The treatment of cancerous tumours in the liver remains clinically challenging, despite wide range possibilities, including radio-frequency ablation (RFA), high-intensity focused ultrasound and resection, which are currently available. Each has its own advantages disadvantages. For non- or minimally invasive modalities, such as RFA, considered here, it is difficult to monitor vivo . This particularly problematic liver, where large blood vessels act heat sinks, dissipating delivered shrinking...
There are no satisfactory methods for monitoring oxygen consumption in critical care. To address this, we adapted laser absorption spectroscopy to provide measurements of O2, CO2, and water vapor within the airway every 10 ms. The analyzer is integrated a novel respiratory flow meter that an order magnitude more precise than other meters. Such precision, coupled with accurate alignment gas concentrations flow, makes possible determination O2 by direct integration over time product...
Inhomogeneity in the lung impairs gas exchange and can be an early marker of disease. We hypothesized that highly precise measurements contain sufficient information to quantify many aspects inhomogeneity noninvasively. Our aim was explore whether one parameterization could both fit such data provide reliable parameter estimates. A mathematical model inhomogeneous developed, containing parameters for compliance, vascular conductance, dead space, all relative volume. Inputs were respiratory...
Existing techniques for the non-invasive in vivo study of dynamic changes skeletal muscle metabolism are subject to several limitations, example, poor signal-to-noise ratios which result long scan times and low temporal resolution. Hyperpolarized [1-13C]pyruvate magnetic resonance spectroscopy (HP-MRS) allows real-time visualization metabolic processes has been used extensively cardiac metabolism, but not resolved oxidative phosphorylation contracting muscle. Combining HP-MRS with an...
A number of mathematical models have been produced that, given the Pco2 and Po2 blood, will calculate total concentrations for CO2 O2 in blood. However, all these contain at least some empirical features, thus do not represent underlying physicochemical processes an entirely mechanistic manner. The aim this study was to develop a model carriage by blood determine whether our understanding physical chemistry major chemical components together with their interactions is sufficiently strong...
Abstract Providing students with detailed, descriptive feedback and having them reflect on what they have learned can foster self-directed learning (Ambrose, 2013); a critical ability for future engineers whom need to be able translate their skills knowledge novel situations (Bary & Rees, 2016). Standards-based grading (SBG) has been slowly emerging in the engineering education field as way provide how well are meeting course objectives (Carberry, et. al., This approach contrasts traditional...
Abstract Introduction: Reflective practices have been used in conjunction with many evidence-based strategies, including standards-based grading [1] to tailor student learning and efforts are known increase awareness about [2]. This study investigated the implementation of different reflective a laboratory course that uses grading. We hypothesized reflecting while completing deliverables addition post-submission reflection would enhance as measured by system when compared only...
It has been suggested that Coxsackie B virus infections may play a part in causing or triggering myocardial infarction. This study was designed to compare the incidence of such Coronary Care Unit patients and normal controls. The choice suitable criterion for diagnosis infection is discussed fully. Two hundred fifty admissions 100 control subjects had serum sample tested by microneutralisation antibodies. among 130 diagnosed as acute infarction 5% compared with 4% group. In subgroup...
Summary Pneumopericardium and pneumomediastinum have been described as complications of endotracheal intubation assisted ventilation in neonates children. Here the occurrence these an adult is possible mechanism discussed.
Identification of salvageable brain tissue is a major challenge when planning the treatment ischaemic stroke. As standard technique used in this context, perfusion-diffusion mismatch, has not shown total accuracy, there an ongoing search for new imaging protocols that could better identify region at risk and physiological models could, on one hand, incorporate imaged parameters predict evolution condition individual, and, other future biomarkers thus suggest directions design protocols....
Ablation techniques have become a widespread choice for the treatment of cancerous tumors which surgical resection poor prognosis. The minimally invasive nature and high success rate when performed by experienced clinicians mean that ablation is likely to remain core technique. However, can drop off dramatically less-experienced operators are involved, it particularly difficult kill all tumor only tumor, given dynamic processes lead cell death. Mathematical modeling response has long...
We compute the Gaseous Dynamical Friction (GDF) force experienced by massive perturbers on elliptical Keplerian orbits. In this paper, we investigate density wake morphology, dynamical friction force, and secular orbital evolution for single as well equal mass binaries embedded in an homogenous, static background flow. all cases, rate-of-change semi-major axis is found to be negative (as expected), whereas eccentricity strictly-subsonic trajectories positive strictly-supersonic trajectories....

Nineteen patients with hay fever symptoms received nine weekly injections of pyridine-extracted alum-precipitated grass pollen vaccine (Alavac P). The results were compared agroup twenty who a three injection series glutaraldehyde-modified pollen-tyrosine (Pollinex). In both groups 65% had subjective improvement in their and no significant difference symptom scores was obtained throughout the season. Pollinex group lower incidence systemic side effects recorded.
Data below 1 mm voxel size is getting more and common in the clinical practice but it still hard to obtain a consistent collection of such datasets for medical image processing research. With this paper we provide large Contrast Enhanced (CE) Computed Tomography (CT) data from porcine animal experiments describe their acquisition procedure peculiarities. We have acquired three CE-CT phases at highest available scanner resolution 57 livers during induced respiratory arrest. These capture...
A model is presented that an alternative approach to the bio-heat equation for use in radio frequency heating of liver. The comprises both a tissue subvolume and blood subvolume. Separate equations are determined each subvolume, but with additional term exchanging heat between them, thus creating coupled system. derivation two differential outlined sample simulations demonstrate importance considering subvolumes separately, even when small fraction
Summary In a prospective study we identified group of 12 patients diagnosed as having acute myocardial infarction but with electrocardiographic features non-transmural and serological evidence recent Coxsackie B infection favouring the possibility myocarditis. The included 9 females 3 males, aged from 38–60 y. Coronary arteriography was carried out in 11 patients. Eight showed no significant (≥ 50%) coronary arterial obstruction. We suggest that artery disease did not contribute to clinical...
Abstract Standards-based grading (SBG) involves the creation of course learning objectives (LO) and linking these to particular aspects assignments. Assignments are created such that students have opportunity show mastery in a objective multiple times over course. This approach aligns student assessment with intended outcomes, rather than traditional score-based grading. The technique has been implemented extensively K-12, but we just now beginning assess its use engineering higher...
