A real-time kernel which supports concurrent programming in Pascal is described. It implements semaphores for mutual exclusion and events for other synchronization. The kernel also offers the possibility to program I/O handlers. The kernel is written in Pascal, but relies on a small number of assembly written procedures for process creation, transfer between processes and handling of interrupts. T
A transmitter consisting of a voltage controlled oscillator (VCO) and power amplifier (PA) for the 400 MHz Medical Implanted Communication System band (MICS) was built in a standard 0.35-μm CMOS process. A push pull architecture was used for both the VCO and the PA. Two off-chip inductors were needed. The design was optimized for 400 μW output power at 3 V supply, which resulted in an efficiency o
Background: Cholecystokinin (CCK) concentrations in plasma have been shown to be significantly higher in colectomised subjects compared to healthy controls. This has been ascribed to reduced inhibition of CCK release from colon. In an earlier study CCK in all but one woman who was colectomised, induced release of oxytocin, a peptide present throughout the gastrointestinal (GI) tract. The aim of th
Background: Patients with acute respiratory failure caused by cardiogenic pulmonary edema (CPE) may require mechanical ventilation that can cause further lung damage. Our aim was to determine the impact of ventilatory settings on CPE mortality. Methods: Patients from the LUNG SAFE cohort, a multicenter prospective cohort study of patients undergoing mechanical ventilation, were studied. Relationsh
Background: Optimal infusion rate of colloids in patients with suspected hypovolemia is unknown, and the primary objective of the present study was to test if plasma volume expansion by 5% albumin is greater if fluid is administered slowly rather than rapidly. Methods: Patients with signs of hypoperfusion after major abdominal surgery were randomized to intravenous infusion of 5% albumin at a dose
Background: Careful assessment of the reasons for discontinuation of active surveillance (AS) is required for men with prostate cancer (PCa). Objective: Using Movember's Global Action Plan Prostate Cancer Active Surveillance initiative (GAP3) database, we report on reasons for AS discontinuation. Design, setting, and participants: We compared data from 10 296 men on AS from 21 centres across 12 co
The emergence of a monkeypox (MPOX) outbreak in 2022 represented the most recent recognizable public health emergency at a global level. Improving knowledge and attitude towards MPOX, particularly among healthcare workers (HCWs), can be a valuable approach in public health preventive efforts aiming to halt MPOX virus spread. The aim of the current study was to evaluate the knowledge and attitude o
The Reference Values for Arterial Stiffness Collaboration has derived an equation using age and mean blood pressure to estimated pulse wave velocity (ePWV), which predicted cardiovascular events independently of Systematic COoronary Risk Evaluation (SCORE) and Framingham Risk Score. The study aim was to investigate the independent association between ePWV and clinical outcomes in 107 599 apparentl
BACKGROUND: Firefighting foam-contaminated ground water, which contains high levels of perfluoroalkyl substances (PFAS), is frequently found around airports. In 2018 it was detected that employees at a municipal airport in northern Sweden had been exposed to high levels of short-chain PFAS along with legacy PFAS (i.e., PFOA, PFHxS, and PFOS) through drinking water.OBJECTIVES: In this study, we aim
The overarching objective of this study was to produce a disaggregated SMOS Soil Moisture (SM) product using land surface parameters from a geostationary satellite in a region covering a diverse range of ecosystem types. SEVIRI data at 15 min temporal resolution were used to derive the Temperature and Vegetation Dryness Index (TVDI) that served as SM proxy within the disaggregation process. West A
Bacteria of the genera Bacillus and Clostridium can form endospores as a strategy to survive unfavourable environmental conditions. Endospore formation involves synthesis of cortex, a thick layer of modified peptidoglycan that surrounds the spore. This layer is required for heat resistance of the spore and mutant spores lacking the cortex layer can be identified by a simple heat shock assay. B. su
Photosynthesis is the process through which the energy from the sun is converted into chemically bound energy stored in carbohydrates. Due to large variations in light intensities and stress situations, plants must be able to regulate the absorbed energy since excess energy would otherwise damage the plant. One of several photoprotective mechanisms involves the xanthophyll cycle. A copper binding
OBJECTIVE: This nationwide study aimed to determine whether venous thromboembolism (VTE) shares familial susceptibility with aortic aneurysm (AA), peripheral artery disease (PAD) and arterial thrombosis and embolisation (ATE) in locations other than the heart and brain.METHODS: Nationwide Swedish family study. Data from the Swedish Multi-Generation Register for subjects aged 0-78 years old, coveri
Background: Thiopentone elimination has been described using Michaelis-Menten pharmacokinetics in adults after prolonged infusion or overdose, but there are few reports of elimination in neonates. Methods: Time-concentration profiles for neonates (n=37) given single-dose thiopentone were examined using both first-order (constant clearance) and mixed-order (Michaelis-Menten) elimination processes u
