A novel fluorescent i-motif DNA silver nanoclusters system has been developed for visualization of reactive oxygen species in plants, enabling the detection of intracellular signaling in plant cells. Reactive oxygen species (ROS) are crucial in plant growth, defense, and stress responses, making them vital for improving crop resilience. Various ROS sensing methods for plants have been developed to detect ROS in vitro and in vivo.

Background: Children attending day-care centers (DCCs) experience more infections than those cared for at home and DCC employees have high sickness absence rates. This study aimed to investigate the association between indoor air quality (IAQ) and absenteeism among children and staff in DCCs.

Methods: CO levels, relative humidity (RH), and temperature were continuously measured in 22 DCCs over three winter months.

Hydrophobic pollutants, such as the antidepressant sertraline (SER), tend to sorb to particles in the water column and subsequently accumulate in the sediment. Long-term exposure to these pollutants may significantly affect sediment-dwelling organisms´ fitness and behavior. To address this knowledge gap, we investigated the impact of chronic exposure to a range of environmentally relevant and higher concentrations of sediment-associated SER on the deposit-feeding polychaete Capitella teleta.

Stormwater is recognised as a vector for microplastics (MPs), including tyre wear particles (TWPs) from land-based sources to receiving waterbodies. Before reaching the waterbodies, the stormwater may be treated. In this study, sediments from six treatment facilities (five retention ponds and a subsurface sedimentation tank) were analysed to understand MP occurrence, concentrations, sizes, polymer types and distribution between inlet and outlet.

Road traffic noise and breast cancer: DNA methylation in four core circadian genes.

Clin Epigenetics

November 2024

Division of Occupational and Environmental Medicine, Department of Laboratory Medicine, Lund University, Lund, Sweden.

Background: Transportation noise has been linked with breast cancer, but existing literature is conflicting. One proposed mechanism is that transportation noise disrupts sleep and the circadian rhythm. We investigated the relationships between road traffic noise, DNA methylation in circadian rhythm genes, and breast cancer.

In this paper, we present a qualitative meta-ethnographic synthesis of 26 articles reporting experiences of subjective burden in 389 parents of children with mental illnesses. The studies were identified through a systematic literature search of PubMed, CINAHL Ultimate, APA PsycInfo, and MedLine Ultimate. We conducted a quality appraisal and followed the seven stages of meta-ethnographic synthesis.

Aim: Previous studies have demonstrated that contact lenses coated with the antimicrobial cationic peptide Mel4, a derivative of melimine, can reduce the occurrence of keratitis. However, the antimicrobial activity of Mel4 weakened over time due to its susceptibility to proteolytic degradation. Oligo-N-substituted glycine peptoids such as TM5 and TM18 possess antimicrobial properties and are resistant to proteolytic breakdown.

This study investigates the role of language in cross-sector collaboration between mental health hospitals and municipalities, focusing on the challenges of maintaining continuity of care and integrating patient-centered approaches. Using Fairclough's framework for critical discourse analysis, we examined focus group interviews with 21 healthcare professionals, including nurses, social workers, and psychiatrists, to identify key themes and patterns in how cross-sector collaboration is discussed. The analysis revealed a dominant medicalized discourse in hospital settings, which often emphasized structured care processes like treatment plans and medication management, overshadowing more flexible, patient-centered approaches common in community-based services.

Background: Medication overuse headache is a prevalent secondary headache due to the overuse of analgesics, mainly over-the-counter analgesics. Over-the-counter analgesics have been associated with disrupted male endocrinology, while the effects on female endocrinology remain nearly unknown. The aim was to understand the effect of long-term analgesic exposure in females with medication overuse headache on Anti-Müllerian hormone, a surrogate measure of female fertility.

Existence of a maximum flow rate in electro-osmotic systems.

J Chem Phys

November 2024

"Glass and Time," IMFUFA, Department of Science and Environment, Roskilde University, Roskilde 4000, Denmark.

In this work, we investigate the effect of the hydrodynamic wall-fluid friction in electro-osmotic flows. First, we present the solution to the electro-hydrodynamic equation for the electro-osmotic velocity profile, which is derived for an ionic system composed of cations immersed in uncharged solvent particles. The system (solution and walls) is kept electrically neutral using negatively charged walls and will here be referred to as a "counterion-only" system.

Density scaling and isodynes in glycerol-water mixtures.

Phys Chem Chem Phys

November 2024

"Glass and Time", IMFUFA, Department of Science and Environment, Roskilde University, Postbox 260, DK-4000 Roskilde, Denmark.

This paper presents dielectric and neutron spectroscopy data on two different glycerol-water mixtures at elevated pressures. Glycerol-water liquid mixtures have a high concentration of hydrogen bonds which usually is expected to lead to complex dynamics. However, with regard to the pressure dependence of the dynamics we reveal a surprisingly simple picture.

Estimating the optimal age for infant measles vaccination.

Nat Commun

November 2024

Infectious Disease Epidemiology group, Max Planck Institute for Infection Biology, Charitéplatz 1, Campus Charité Mitte, Berlin, Germany.

Article Synopsis
  • The persistence of measles in various countries highlights significant gaps in immunity due to incomplete immunization with measles-containing vaccines (MCVs).
  • A new mathematical model was developed to analyze the trade-off between vaccination age and MCV1 effectiveness, aiming to find the best age for administering the vaccine.
  • The study predicts a wide range of optimal vaccination ages (6-20 months) that vary based on local measles transmission and vaccination coverage, suggesting that public health strategies could be customized for better measles control.

Isolation and Analysis of Mitochondrial Small RNAs from Rat Liver Tissue and HepG2 Cells.

Methods Mol Biol

November 2024

Department of Science and Environment, Roskilde University, Roskilde, Denmark.

The presence of non-coding RNAs, such as microRNAs (miRNAs), in mitochondria has been reported by several studies. The biological roles and functions of these mitochondrial miRNAs ("mitomiRs") have not been sufficiently characterized, but the mitochondrial localization of miRNAs has recently gained significance due to modified mitomiR-populations in certain states of diseases. Here, we describe the isolation and analysis of mitochondrial RNAs from rat liver tissue and HepG2 cells.
