This paper presents the specification, design, and development of Visible Camera (VIS) on European Space Agency's mission. VIS is a large optical-band imager with field view 0.54 deg$^2$ sampled at an array 609 Megapixels spatial resolution . It will be used to survey approximately 14 000 extragalactic sky measure distortion galaxies in redshift range $z=0.1$--1.5 resulting from weak gravitational lensing, one two principal cosmology probes leveraged by With photometric redshifts,...

Abstract Cardiac troponin (cTn) is a sensitive test to assess for myocardial injury. However certain clinical situations can result in raised cTn the absence of cardiac involvement. Here we present case 65-year-old woman on long term atorvastatin who presented with generalised weakness, non-specific chest pain, and persistently elevated high sensitivity T. Upon further investigation acute injury was excluded diagnosis statin-induced immune mediated necrotising myopathy (IMNM) made. The...

Robust markers that predict prognosis and detect early treatment response in malignant pleural mesothelioma (MPM) would enhance patient care. Consecutive patients with MPM who were considered fit for first-line chemotherapy prospectively recruited. Patients of similar performance status opting best supportive care included as a comparator group. Baseline interval CT, PET-CT serum (mesothelin, fibulin-3 neutrophil–lymphocyte ratio (NLR)) obtained, followed up minimum 12 months. Seventy-three...

Abstract The SEL-I-METRY trial (EudraCT No 2015-002269-47) is the first multicentre to investigate role of 123 I and 131 SPECT/CT-based tumour dosimetry predict response radioiodine therapy. Standardised methodology essential provide a robust evidence-base for absorbed dose–response thresholds molecular radiotherapy (MRT). In this paper practical standardised protocol used establish network centres with consistent methods activity quantification. Nine SPECT/CT systems at eight were set-up...

Rates of peroxidation human LDL and rates consumption the LDL's α-tocopherol (TocH) have been measured at 37 °C. Peroxidation was initiated by radicals generated in aerated aqueous phase known thermal decomposition appropriate precursors: superoxide (O2•-/HOO•) from a hyponitrite alkylperoxyls (ROO•, two positively charged, one negatively charged neutral) azo compounds. The efficiencies escape solvent cage geminate pair neutral carbon-centered found to be 0.1, but it 0.5 for three radicals,...

Objective: Acute kidney injury (AKI) post-cardiac surgery is associated with mortality rates approaching 20%. The development of effective treatments hindered by the poor homology between rodent models, mainstay research into AKI, and that which occurs in humans. This pilot study aims to characterise post-cardiopulmonary bypass (CPB) AKI an animal model potentially greater cardiac patients. Methods results: Adult pigs, weighing 50–75 kg, underwent 2.5 h CPB. Pigs undergoing saphenous vein...

The effect of chemotherapy on health-related quality life (HRQoL) in malignant pleural mesothelioma (MPM) is poorly understood. Patient-individualised prognostication and prediction treatment response from useful but little evidence exists to guide practice. Consecutive patients with MPM who were fit for first-line pemetrexed cisplatin\carboplatin recruited followed up a minimum 12 months. This study focussed the HRQoL outcomes these using EQ-5D, EORTC QLQ-C30 LC13. Seventy-three which 58...

The authors propose a novel spatiotemporal constraint based on shape and appearance combine it with level‐set deformable model for left ventricle (LV) segmentation in four‐dimensional gated cardiac SPECT, particularly the presence of perfusion defects. incorporates information into ‘soft‐to‐hard’ probabilistic constraint, utilises regularisation via maximum posteriori framework. This force allows more flexibility than rigid forces constraint‐only schemes, as well other state art joint...

Introduction Animal studies have shown Zoledronic Acid (ZA) may diminish pleural fluid accumulation and tumour bulk in malignant disease (MPD). We performed a pilot study to evaluate its effects humans. Methods undertook single centre, double-blind, placebo-controlled trial adults with MPD. Patients were randomised (1:1) receive 2 doses of intravenous ZA or placebo, 3 weeks apart followed-up for 6 weeks. The co-primary outcomes change Visual Analogue Scale (VAS) score measured breathlessness...

A mathematical model for deposit detachment and removal during the backwash of rapid gravity filters has been derived a fluidising water wash. The consists two parts; part 1 determines volume dislodged into suspension at any instant, 2 change in concentration emerging from filter bed stage backwash. Initial conditions are determined filtration model.
