BACKGROUND: Long-term oxygen therapy (LTOT) improves survival in patients with chronic severe resting hypoxaemia, but effects on hospitalisation are unknown. This study evaluated the potential impact of starting LTOT on acute exacerbation and hospital burden in patients with chronic obstructive pulmonary disease (COPD), interstitial lung disease (ILD) and pulmonary hypertension (PH).METHODS: Longi

Deoxynivalenol (DON) is a common mycotoxin in crops that could induce intestinal inflammation, affecting the susceptibility of intestinal epithelial cells (IECs) to pathogen infection. This study aimed to investigate DON's effects on mucin and cytokine production as part of the local immune system and how it affected intestinal susceptibility to pathogen infection. Caco-2 cells were exposed to DON

Ethanolamines are often added in the empirical formulation of commercial hard-surface cleaners and degreasers. Their use is usually justified by the fact they are anti-corrosive agents. However, their direct influence on cleaning performance is not well understood. In this work the cleaning performance of formulations with and without mono-ethanolamine (MEA) have been tested on standard polymerize

BACKGROUND: Several widely used drugs have photosensitizing properties, and much research has been conducted to find associations between their use and the risk of developing cutaneous malignant melanoma (cM), basal cell carcinoma (BCC) or cutaneous squamous cell carcinoma (cSCC), often with conflicting results.OBJECTIVE: To assess whether the use of commonly prescribed photosensitizing drugs incr

The increasing demand for renewable energy accounts for the DC microgrid concept, facilitating the integration of photovoltaic (PV) modules and battery energy systems (BESS) into a common DC bus. In light of this, bipolar DC-DC converters can result in two symmetric DC buses that provide more flexibility. This article presents a hybrid bipolar converter by merging a single-ended primary-inductor c

Power converters of DC-DC nature are pivotal to supplying power in electronics, charging equipment, and renewable energy integration along with AC-DC converters. They are frequently used in most of the power supplies of electronic devices as well as dedicated high-energy functionalities including charging battery cells, electroplating, and welding. Furthermore, DC-DC switching regulators not only

Converters of AC-DC nature are pivotal to supplying power in electronics, charging equipment, and renewable energy integration. A closed-loop Cuk converter with switched capacitor network and PID controller was proposed in this paper to mitigate the limitations of open circuit Cuk converter topology to ensure improved power factor from input along with low distortion in output, making it ideal for

The development of an artificial neural network to analyze power system faults is currently under way. However, the produced system is unsatisfactory because it is prone to failure and takes longer to detect faults. The ultimate goal of this project is to create an artificial neural network system that can identify and classify all forms of faults in power grid lines soon after they occur. In prin

Microelectronic systems, wind energy applications, battery chargers, DC motor controllers, and home electric appliances all require AC/DC converters for power supply. With a high voltage conversion ratio and minimal EMI emissions, switching capacitor (SC) based converters could be a promising answer to the difficulties of the present century. A bridge SEPIC PFC converter with a mono-switching capa

The performance of graphene-based and multilayer MoS2 based MSM (metal-semiconductor-metal) photodetectors is compared in this study using analytical analysis and simulation. At varying voltages, optical powers, and wavelengths, the total illuminated current, photocurrent, and photo responsivity in these two photodiodes show distinct findings. While adjusting the wavelength of the incident light a

Power supplies for microelectronic systems, battery chargers, wind energy applications, electric appliances in the household and dc motor drives require AC-DC converters. The proposed bridgeless Cuk PFC converter in this paper is featured with common ground, transformerless structure, and clear energy delivery process. The absence of bridge rectifiers, transformer and the presence of only two semi

AC-DC converters are mostly used as power supplies for microelectronic systems, battery chargers, wind energy applications, electric appliances in household and dc motor drives. Switched-capacitor (SC) network based converters can be good solution to the challenges of 21st century having high voltage conversion ratio and low EMI emissions. The application of this type of converters is in microproc

The nasal mucosa is the first immunologically active site that respiratory viruses encounter and establishing immunity at the initial point of pathogen contact is essential for preventing viral spread. Influenza A virus (IAV) in humans preferentially replicates in the upper respiratory tract (URT) but mouse models of infection result in lower respiratory tract infection. Here, we optimize IAV inoc

Ledelse er et af de mest omtalte og undersøgte fænomener i moderne organisationer. Det bliver ofte fremhævet som nøglen til succes. Men er ledelse virkelig den universelle løsning på alle organisatoriske udfordringer, og hvordan udfolder det sig i praksis, når ledere forsøger at omsætte ambitioner til handling? Denne bog går bag om de velkendte fortællinger og præsenterer et mere nuanceret billede

OBJECTIVE: To explore the associations between daily time in sedentary behaviour (SED) and physical activity (PA) with perceived physical capacity, health-related quality of life (HRQoL) and fatigue in persons with post COVID-19 condition (PCC). An additional objective was to describe changes in SED and PA levels over three months.MATERIALS AND METHODS: Individuals with PCC self-reported on physic
