Label-free detection of polystyrene nanoparticles in Daphnia magna using Raman confocal mapping

Micro- and nanoplastic pollution has emerged as a global environmental problem. Moreover, plastic particles are of increasing concern for human health. However, the detection of so-called nanoplastics in relevant biological compartments remains a challenge. Here we show that Raman confocal spectroscopy-microscopy can be deployed for the non-invasive detection of amine-functionalized and carboxy-fu

Minimal reporting guideline for research involving eye tracking (2023 edition)

A guideline is proposed that comprises the minimum items to be reported in research studies involving an eye tracker and human or non-human primate participant(s). This guideline was developed over a 3-year period using a consensus-based process via an open invitation to the international eye tracking community. This guideline will be reviewed at maximum intervals of 4 years.

Women and youth in Sarajevo entrepreneurship ecosystem : promoting inclusive entrepreneurship ecosystems for women and youth

It is evident that Sarajevo has major challenges to create a dynamic culture around entrepreneurship. The reports also outline major constraints entrepreneurs face when hiring and retaining qualified labour. By applying the ILO’s Inclusive Entrepreneurship Ecosystem Framework, this report presentsthe root causes behind these challenges, and proposes ways forward to better include women and young p

Women and youth in Banja Luka entrepreneurship ecosystem : promoting inclusive entrepreneurship ecosystems for women and youth

By applying the ILO’s inclusive entrepreneurship ecosystem model, this report outlines key developments and challenges in the ecosystem for women and young entrepreneurs in Banja Luka. Numerous challenges identified under each pillar of the entrepreneurship ecosystem influence the pathways for decent work of women and young entrepreneurs who are part of the ecosystem, but many challenges can also

Intra- and inter-rater reliability of compressed breast thickness, applied force, and pressure distribution in screening mammography

BackgroundEnsuring equivalent and reproducible breast compression between mammographic screening rounds is important for the diagnostic performance of mammography, yet the extent to which screening mammography positioning and compression is reproducible for the individual woman is unknown.PurposeTo investigate the intra- and inter-rater reliability of breast compression in screening mammography.Ma

Translational opportunities of single-cell biology in atherosclerosis

The advent of single-cell biology opens a new chapter for understanding human biological processes and for diagnosing, monitoring, and treating disease. This revolution now reaches the field of cardiovascular disease (CVD). New technologies to interrogate CVD samples at single-cell resolution are allowing the identification of novel cell communities that are important in shaping disease developmen

Multiproxy Reconstructions of Integral Energy Spectra for Extreme Solar Particle Events of 7176 BCE, 660 BCE, 775 CE, and 994 CE

Extreme solar particle events (ESPEs) are rare and the most potent known processes of solar eruptive activity. During ESPEs, a vast amount of cosmogenic isotopes (CIs) 10Be, 36Cl, and 14C can be produced in the Earth's atmosphere and deposited in natural stratified archives. Accordingly, CI measurements in these archives allow us to evaluate particle fluxes during ESPEs. In this work, we present a

Explicit harmonic morphisms and p-harmonic functions from the complex and quaternionic Grassmannians

We construct explicit complex-valued p-harmonic functions and harmonic morphisms on the classical compact symmetric complex and quaternionic Grassmannians. The ingredients for our construction method are joint eigenfunctions of the classical Laplace-Beltrami and the so called conformality operator. A known duality principle implies that these p-harmonic functions and harmonic morphisms also induce

Clinical efficacy of a topical lactic acid bacterial microbiome in chronic rhinosinusitis: A randomized controlled trial

AbstractObjectiveA locally disturbed commensal microbiome might be an etiological factor in chronic rhinosinusitis (CRS) in general and in CRS without nasal polyps (CRSsNP) in particular. Lactic acid bacteria (LAB) have been suggested to restore commensal microbiomes. A honeybee LAB microbiome consisting of various lactobacilli and bifidobacteria have been found potent against CRS pathogens in vitObjectiveA locally disturbed commensal microbiome might be an etiological factor in chronic rhinosinusitis (CRS) in general and in CRS without nasal polyps (CRSsNP) in particular.

Kraft Lignin : A Valuable, Sustainable Resource, Opportunities and Challenges

Kraft lignin, a by-product from the production of pulp, is currently incinerated in the recovery boiler during the chemical recovery cycle, generating valuable bioenergy and recycling inorganic chemicals to the pulping process operation. Removing lignin from the black liquor or its gasification lowers the recovery boiler load enabling increased pulp production. During the past ten years, lignin se

Altered gut microbiota community structure and correlated immune system changes in dibutyl phthalate exposed mice

Di-n-butyl phthalate (DBP) is a ubiquitous environmental contaminant linked with various adverse health effects, including immune system dysfunction. Gut microbial dysbiosis can contribute to a wide range of pathogenesis, particularly immune disease. Here, we investigated the impact of DBP on the gut microbiome and examined correlations with immune system changes after five weeks oral exposure (10

Sex‐based differences in cardiac resynchronization therapy upgrade and outcome for patients with pacemaker and new‐onset heart failure

BackgroundPatients with chronic right ventricular (RV) pacing are at an increased risk of heart failure. Previous studies have indicated that cardiac resynchronization therapy (CRT) is underused in this setting, and that there may be sex-based differences in both CRT use and clinical outcome.ObjectiveTo evaluate sex-based differences in CRT use and clinical outcome for patients with new-onset hear

Availability of laparoscopic surgery in Mexico's public health system : a nationwide retrospective analysis

BACKGROUND: Laparoscopic surgery remains limited in low-resource settings. We aimed to examine its use in Mexico and determine associated factors.METHODS: By querying open-source databases, we conducted a nationwide retrospective analysis of three common surgical procedures (i.e., cholecystectomies, appendectomies, and inguinal hernia repairs) performed in Mexican public hospitals in 2021. Procedu

Adverse perinatal outcomes after Roux-en-Y Gastric Bypass vs. Sleeve Gastrectomy : a systematic review

BACKGROUND: Pregnancies occurring after bariatric surgery are associated with various perinatal complications. However, there may be differences in the type of perinatal complications occurring after different methods of bariatric surgery. The aim of the current study was to compare adverse perinatal outcomes in pregnant women following Roux-en-Y Gastric Bypass (RYGB) vs. Sleeve Gastrectomy (SG).M

Quad-element LTE hidden car roof antenna system

This work presents the systematic design and optimization of a compact quad-element MIMO antenna system in a roof cavity for the expected channel behavior at a 700 MHz LTE band. Beginning with a standard low-profile antenna element, the desired radiation pattern is synthesized by structural modification. The configuration for a quad-element design is then optimized. The results show that the propo

A Population-Based Study of Unfavorable Prognostic Factors Associated With Pyogenic Liver Abscess

BackgroundPyogenic liver abscess (PLA) is a rare entity that is associated with substantial mortality and morbidity. Our objective was to investigate variables associated with mortality and subsequent PLA in patients diagnosed with PLA in southern Sweden.MethodsWe conducted a population-based observational study comprising all episodes of PLA that occurred between 2011 and 2020 in the county of Sk
