Background: During the COVID-19 pandemic, the use of face masks has increased among healthcare workers (HCWs). Questionnaire studies have shown a high frequency of self-reported facial adverse skin reactions. Case reports have been published on face mask-induced allergic contact dermatitis and urticaria. Objectives: To describe the results of the contact allergy investigations in consecutive HCWs
Substrate properties can affect the thermal balance of organisms, and the colored integument, alongside other factors, may influence heat transfer via differential absorption and reflection. Dark coloration may lead to higher heat absorption and could be advantageous when substrates are cool (and vice versa for bright coloration), but these effects are rarely investigated. Here, we examined the ef
Background In the early 1980s, a preservative containing a mixture of methylchloroisothiazolinone (MCI) and methylisothiazolinone (MI) in a ratio of 3:1 was introduced. This mixture (mix) has been patch tested at 100 ppm (0.01%) worldwide and at 200 ppm (0.02%) in Sweden since 1986 and also in the European baseline series since 2014. Objective A new aqueous mix of MCI 0.015% and MI 0.2% was compar
This paper proposes Yggdrasil, a protocol for privacy-aware dual data deduplication in multi-client settings. Yggdrasil is designed to reduce cloud storage space while safeguarding the privacy of clients’ data. This is achieved by exploiting a ‘dual’ setting, where both the cloud and the clients store a fraction of the data. Yggdrasil combines two innovative techniques to achieve this goal. First,
Quinoa stalks glucuronoarabinoxylan (QSGAX) has been extracted by alkali and further utilized for production of two-types of xylooligosaccharides (XOs): i) enzymatically produced glucuronosylated-XOs (GXOs), and ii) a dilute acid produced mixture of non-substituted/substituted XOs of different degree of polymerization (DP). The respective mixtures were then separately evaluated as prebiotics by an
Microglial cells are affected in Alzheimer's disease (AD) and interact with amyloid-beta (Aβ) plaques. Apart from memory loss, depression is common in patients with AD. Electroconvulsive therapy (ECT) is an anti-depressive treatment that may stimulate microglia, induce neuroinflammation and alter the levels of soluble Aβ, but the effects of ECT on microglia and Aβ aggregation in AD are not known.
The purpose of this study was to investigate one-year changes and differences in changes in activities of daily living (ADL), usability, a history of falls, concerns about falling, and self-rated health across five housing adaptation (HA) client profiles identified previously using a cluster analysis approach: older adults with low level of disability (n = 59); older adults with medium/high level
The study aims to understand the influence of environmental and lifestyle factors and more specifically the role of tobacco smoke–infused water (tuibur) on Helicobacter pylori infection. It was a cross-sectional study to measure the epidemiological risk factors associated with H. pylori infection among the tribal population in Northeast India. Endoscopic samples were collected from the antrum regi
Purpose This study explored the role of several psychological factors in professional quality of life in nurses. Specifically, we tried to clarify the relationships between several dimensions of empathy, self-compassion, and psychological inflexibility, and positive (compassion satisfaction) and negative (burnout and compassion fatigue) domains of professional quality of life. Methods Using a cros
The diversity of bacteriophages is likely unparalleled in the biome due to the immense variety of hosts and the multitude of viruses that infect them. Recent efforts have led to description at the genomic level of numerous bacteriophages that infect the Actinobacteria, but relatively little is known about those infecting other prokaryotic phyla, such as the purple non-sulfur photosynthetic α-prote
Trimethylolpropane (TMP) is an important industrial chemical used to produce various value-added chemicals and polymers. In this study, both biobased butyraldehyde and formaldehyde were produced by the incomplete oxidation of bio-1-butanol and biomethanol, respectively, and were then used to produce a biobased TMP. High selective incomplete oxidation of primary alcohol to aldehyde is a challenging
This article investigates trapping mechanisms in AlGaN/GaN high electron mobility transistors (HEMTs) at cryogenic temperatures (CTs) down to 4.2 K, using pulsed I–V and drain current transient spectroscopy (DCTS) measurements. The results revealed an overall increase of trapping effects at CT. In particular, a substantial increase in current collapse at low temperatures was observed and predomina
BACKGROUND: Sharp force injuries display varying patterns depending on the manner of death (homicide, suicide, accidental). The purpose of this study was to analyse forensic autopsy data to examine the characteristics of sharp force injuries on the extremities, to differentiate between different manners of death and to examine demographic differences.METHODS: This retrospective cohort study utiliz
Over geologic time, biocalcification – the process by which marine organisms make calcium carbonate (CaCO3) – has reshaped climates, ocean life, and seawater chemistry. In particular, the evolution of coccolithophores, the largest group of nannoplankton and today’s most productive calcifiers, transformed ocean environments and the carbon cycle. Their origins, however, remain enigmatic. This is par
High-grade serous ovarian cancer (HGSOC) is the most prevalent and aggressive subtype of ovarian cancer. The combination of late-stage diagnosis and the tendency to exhibit resistance to existing treatments highlights a critical gap in effective therapeutic options. There is thus a need for novel strategies for targeting HGSOC, particularly in its advanced stages. To address this gap, we developed
An experimental study of smoke propagation from an apartment to an escape route corridor in a real-scale residential building is presented in this paper. The experiments were performed using the same experimental setup but with different ventilation and apartment door opening times. The setup consisted of a fire in a two-seater sofa in an apartment connected to a corridor and other apartments. A t
