BACKGROUND: Spatial epidemiological analyses primarily depend on spatially-indexed medical records. Some countries have devised ways of capturing patient-specific spatial details using ZIP codes, postcodes or personal numbers, which are geocoded. However, for most resource-constrained African countries, the absence of a means to capture patient resident location as well as inexistence of spatial d

In the formulation of an active enzyme enclosed in a matrix for controlled delivery, it is a challenge to achieve a high protein load and to ensure high activity of the protein. For the first time to our knowledge, we report the use of a highly swollen lipid sponge (L3) phase for encapsulation of the large active enzyme, β-galactosidase (β-gal, 238 kDa). This enzyme has large relevance for applica

Plastics are widely used in todays society leading to an accelerating amount of plastic waste entering natural ecosystems. Over time these waste products degrade to micro- and, eventually, nanoplastic particles. Therefore, the break-down of plastics may become a critical threat to aquatic ecosystems and several short term studies have demonstrated acute toxicity of nanoplastics on aquatic organism

OBJECTIVES: To investigate if the sport concussion assessment tool version 5 (SCAT5) could be suitable for application to Para athletes with a visual impairment, a spinal cord injury, or a limb deficiency.METHODS: A 16-member expert panel performed a Delphi technique protocol. The first round encompassed an open-ended questionnaire, with round 2 onwards being composed of a series of closed-ended s

We analyse the effects of soil type on mortality of children aged 2-15 living in five rural parishes in Sweden between 1850 and 1914. We use micro-level longitudinal demographic data combined with micro-level longitudinal geographic data. Here, the individuals in the parishes are linked to the property units they lived in. We find that, compared to those living in property units covered by 80-100%

Increasing human impact on the environment is causing drastic changes in disturbance regimes and how they prevail over time. Of increasing relevance is to further our understanding on biological responses to pulse disturbances (short duration) and how they interact with other ongoing press disturbances (constantly present). Because the temporal and spatial contexts of single experiments often limi

Urgent structural change is required in higher education to allow collaboration both within and acrossuniversities so that achieving a rapid sustainability transition can become the overarching and mainpurpose of education, research and work in society. A review of the literature reveals that fragmentation,caused by traditional hierarchical faculty and disciplinary organisation, is a major obstacl

The system of welcoming newly arrived students in Sweden has experienced numerous modifications since its inception. Additionally, because the interpretation of education laws us left to the municipalities and head teachers, the various policies have resulted in a multitude of local practices. Over the years, a very wide range of models for organising newcomer reception have therefore been tried o

Farmers as volunteers in research could potentially provide a rich resource for exploring sustainable agricultural research questions. To discern emerging patterns in citizen science-based studies on topics with relevance for sustainable agriculture, and reveal salient challenges and opportunities for conducting such studies, we conducted a systematic literature review of 27 peer-reviewed articles

Despite continued efforts by educators, UN declarations and numerous international agreements, progress is still limited in handling major global challenges such as ecosystem collapse, accelerating climate change, poverty, and inequity. The capacity to collaborate globally on addressing these issues remains weak. This historical review of research on global learning for sustainable development (GL

The colloidal stability of lipid based cubosomes, aqueous dispersion of inverse bicontinuous cubic phase, can be significantly increased by a stabilizer. The most commonly used stabilizers are non-ionic tri-block copolymers, poloxamers, which adsorb at the lipid-water interface and hence sterically stabilize the dispersion. One of the challenges with these synthetic polymers is the effect on the i

The adaptive matched filter (AMF) is a method widely used in spectral unmixing to classify different tissue chromophores in photoacoustic images. However, a threshold needs to be applied to the AMF detection image to distinguish the desired tissue chromophores from the background. In this study, we propose an automatic threshold selection (ATS) algorithm capable of differentiating a target from th

Chronic obstructive pulmonary disease (COPD) is a progressive condition characterized by airway remodeling, including emphysema and fibrosis. Proteoglycans and their glycosaminoglycan (GAG) chains are key components of the extracellular matrix and may be altered as the disease advances. This study analyzed lung tissue from COPD patients (GOLD stages II-III and IV), non-COPD smokers, and non-smoker

This study investigated the presence of microplastics (MPs, >5 μm to <2 mm) in biofertilizers and estimated their mass input to Swedish agricultural soils. Collective samples from representative biogas facilities were analyzed using optical microscopy and optical photothermal infrared (O-PTIR) spectroscopy, with selected MPs examined by scanning electron microscopy (SEM). The highest MPs concentra

Measuring the number concentration of colloidal nanoparticles (NPs) is critical for assessing reproducibility, enabling compliance with regulation, and performing risk assessments of NP-enabled products. For nanomedicines, their number concentration directly relates to their dose. However, the lack of relevant reference materials and established traceable measurement approaches make the validation

Hematopoietic stem cells (HSCs) are rare cells on top of the differentiation hierarchy of hematopoiesis. HSCs are unique in their combined capacity to differentiate into all mature blood lineages and self-renew to maintain the HSC pool. Based on classical models of hematopoiesis in mouse, the self-renewal potential of HSCs is gradually and step-wise lost during the transition from long term (LT)-H
