Skin exposure to scented products used in daily life and fragrance contact allergy in the European general population - The EDEN Fragrance Study

Background: Fragrances are widely used in scented products used in daily life with the potential to induce skin sensitization. Objective: To evaluate exposure to scented products and to explore associations between exposure and fragrance contact allergy. Methods: A cross-sectional study on individuals from 18 to 74 years of age, who were randomly selected from the general population in five Europe

Correlation studies of fission-fragment neutron multiplicities

We calculate neutron multiplicities from fission fragments with specified mass numbers for events having a specified total fragment kinetic energy. The shape evolution from the initial compound nucleus to the scission configurations is obtained with the metropolis walk method on the five-dimensional potential-energy landscape, calculated with the macroscopic-microscopic method for the three-quadra

The sensitivity of ginkgo leaf unfolding to the temperature and photoperiod decreases with increasing elevation

Climate change substantially affects plant phenology, resulting in earlier vegetation onset across temperate and boreal regions. Phenological shifts caused by warming may alter species interactions across trophic levels because of species-specific responses, and influence the reproductive success of dioecious species if the phenological sensitivity to warming (ST) differs between genders. We used

A critical review of the use of lipid signature molecules for the quantification of arbuscular mycorrhiza fungi

Tools for accurate measurements of microbial biomass/abundance are imperative in soil ecology. This perspective was prompted by a lack of consistency in how the neutral lipid fatty acid (NLFA) and phospholipid fatty acid (PLFA) 16:1ω5 are used to estimate arbuscular mycorrhizal (AM) fungal abundance, which we argue can lead to erroneous conclusions within studies and complicate among-study compari

High-resolution carbon isotope chemostratigraphy of the middle Cambrian to lowermost Ordovician in southern Scandinavia : Implications for global correlation

Continuous and biostratigraphically well-constrained carbon isotope (δ13Corg) profiles through the upper Miaolingian (middle Cambrian) to Tremadocian (Lower Ordovician) part of the Alum Shale Formation in four drill cores from southernmost Scandinavia are described. The sections record seven Furongian (upper Cambrian) excursions/spikes, of which three appear valuable as auxiliary markers for ident

Linear strain and stress potential parameters for the three fundamental band to band transitions in β-Ga2O3

We report the strain and stress relationships for the three lowest energy direct band to band transitions at the Brillouin zone center in monoclinic β-Ga2O3. These relationships augment four linear perturbation parameters for situations, which maintain the monoclinic symmetry, which are reported here as numerical values obtained from density functional theory calculations. With knowledge of these

Microbial resilience to drying-rewetting is partly driven by selection for quick colonizers

Rewetting dry soil induces enormous changes in microbial growth and biogeochemistry. Upon drying-rewetting (D/RW), bacteria have been shown to exhibit two different responses: (1) a more resilient response where bacteria start growing immediately with a quick recovery after rewetting and (2) a less resilient response where there is a pronounced lag-period before bacterial growth starts to increase

Developmental disorders caused by haploinsufficiency of transcriptional regulators : a perspective based on cell fate determination

Many human birth defects and neurodevelopmental disorders are caused by loss-of-function mutations in a single copy of transcription factor (TF) and chromatin regulator genes. Although this dosage sensitivity has long been known, how and why haploinsufficiency (HI) of transcriptional regulators leads to developmental disorders (DDs) is unclear. Here I propose the hypothesis that such DDs result fr

Venous thromboembolism in ANCA-associated vasculitis : A population-based cohort study

Objective: To determine incidence rate and predictors of venous thromboembolic events (VTE) in a population-based cohort with ANCA-associated vasculitis (AAV). Methods: The study comprised 325 patients diagnosed with AAV from 1997 to 2016. All cases of VTE from prior to vasculitis diagnosis to the end of the study period were identified. The BVAS was used to assess disease activity at diagnosis. V

Temporal relationship between osteoarthritis and comorbidities : A combined case control and cohort study in the UK primary care setting

Objective: To determine the burden of comorbidities in OA and their temporal relationships in the UK. Methods: The Clinical Practice Research Datalink (CPRD) GOLD was used to identify people with incident OA and age, gender and practice matched non-OA controls from UK primary care. Controls were assigned the same index date as matched cases (date of OA diagnosis). Associations between OA and 49 in

My face turned red, but it led me … nowhere. Notes on epistemically pointless embarrassment in ethnographic practice

The personal character of ethnography makes it meaningful to pay attention to emotions during fieldwork, not the least of which is awkwardness or embarrassment. To make a fool of oneself or to commit a faux pas in the field belongs to the palette of the ethnographic experience, and is often defined as helpful for obtaining new knowledge about the setting. But whereas many ethnographers emphasize t

Bmi1 induction protects hematopoietic stem cells against pronounced long-term hematopoietic stress

The Polycomb complex protein Bmi1 is regarded as a master regulator of hematopoietic stem cells (HSCs). In the blood system, HSCs express Bmi1 most abundantly and Bmi1 expression vanes as cells differentiate. Furthermore, Bmi1 has been found overexpressed in several hematologic cancers. Most studies exploring the normal role of Bmi1 in HSC biology have utilized loss-of-function models, which have

A Global Map of COVID-19 Vaccine Acceptance Rates per Country: An Updated Concise Narrative Review

The delay or refusal of vaccination, which defines vaccine hesitancy, is a major challenge to successful control of COVID-19 epidemic. The huge number of publications addressing COVID-19 vaccine hesitancy necessitates periodic review to provide a concise summary of COVID-19 vaccine acceptance rates worldwide. In the current narrative review, data on COVID-19 vaccine acceptance rates were retrieved

Deep Learning-Based Classification of Cancer Cell in Leptomeningeal Metastasis on Cytomorphologic Features of Cerebrospinal Fluid

Background: It is a critical challenge to diagnose leptomeningeal metastasis (LM), given its technical difficulty and the lack of typical symptoms. The existing gold standard of diagnosing LM is to use positive cerebrospinal fluid (CSF) cytology, which consumes significantly more time to classify cells under a microscope.Objective: This study aims to establish a deep learning model to classify can

Ingressive phonation conveys arousal in human nonverbal vocalizations

Animals normally vocalise while exhaling. Ingressive, or inspiratory, voice production occurs in humans and many other species, but its communicative function, if any, remains unknown. To test the perceptual effects of ingressive phonation, naturally occurring ingressive syllables in 109 human nonverbal vocalisations (55 laughs, 21 cries, and 33 moans) were experimentally attenuated or morphed int
