Host Immunity-Microbiota-Virus Interactions at the Intestinal Mucosal surface in Health and Disease

The presence of viral immune triggers at the intestinal mucosa can have multipleglobal effects on intestinal integrity, including relative protection fromsubsequent inflammatory bowel disease. During the last century, the westernworld has achieved a remarkable success in preventing infectious diseases,which increased the general life expectancy dramatically. However, theincidence and prevalence of

Match length realization and cooperation in indefinitely repeated games

Experimental studies of infinitely repeated games typically consist of several indefinitely repeated games (“matches”) played in sequence with different partners each time, whereby match length, i.e. the number of stages of each game is randomly determined. Using a large meta data set on indefinitely repeated prisoner's dilemma games (Dal Bó and Fréchette, 2018) we demonstrate that the realized le

Circular business models for the fastmoving consumer goods industry : Desirability, feasibility, and viability

Fast-moving consumer goods (FMCGs) are products that have a short useful lifetime and are typically designed for single or limited uses followed by disposal. The disposable nature of FMCGs combined with ineffective waste recovery systems is causing global environmental problems. Various reusable packaging business models have emerged to tackle these problems; however, their influence is still low

Mother's Own Milk and Its Relationship to Growth and Morbidity in a Population-based Cohort of Extremely Preterm Infants

Objectives:The aim of the study was to evaluate the relationships between intake of mother's own milk (MOM), compared with intake of pasteurized donor milk (DM), and postnatal growth, incidence of retinopathy of prematurity (ROP) and bronchopulmonary dysplasia (BPD), in extremely preterm infants.Methods:Swedish population-based cohort of surviving extremely preterm infants born 2004 to 2007. Expos

Paediatric diagnostic reference levels for common radiological examinations using the European guidelines

Objective: The purpose of this study was to explore the feasibility to determine regional diagnostic reference levels (RDRLs) for paediatric conventional and CT examinations using the European guidelines and to compare RDRLs derived from weight and age groups, respectively. Methods: Data were collected from 31 hospitals in 4 countries, for 7 examination types for a total of 2978 patients. RDRLs we

Human studies of mitochondrial biology demonstrate an overall lack of binary sex differences : A multivariate meta-analysis

Mitochondria are maternally inherited organelles that play critical tissue-specific roles, including hormone synthesis and energy production, that influence human development, health, and aging. However, whether mitochondria from women and men exhibit consistent biological differences remains unclear, representing a major gap in knowledge. This meta-analysis systematically examined four domains an

A Palette of Fluorescent Aβ42 Peptides Labelled at a Range of Surface-Exposed Sites

Fluorescence-based single molecule techniques provide important tools towards understanding the molecular mechanism of complex neurodegenerative diseases. This requires efficient covalent attachment of fluorophores. Here we create a series of cysteine mutants (S8C, Y10C, S26C, V40C, and A42C) of Aβ42, involved in Alzheimer’s disease, based on exposed positions in the fibril structure and label the

Neurodevelopmental disorders and somatic diagnoses in a national cohort of children born before 24 weeks of gestation

AIM: This study investigated childhood diagnoses in children born extremely preterm before 24 weeks of gestation.METHODS: Diagnoses of neurodevelopmental disorders and selected somatic diagnoses were retrospectively retrieved from national Swedish registries for children born before 24 weeks from 2007 to 2018. Their individual medical files were also examined.RESULTS: We studied 383 children born

Climate change and land degradation in Africa : A case study in the Mount Elgon region, Uganda

The aim of this study is to estimate and compare soil erosion, in the Mount Elgon region, eastern Uganda, during the last decade. Possible trends and changes in erosion are linked to precipitation/climate change as well as changes in land cover. Two different versions of the Revised Universal Soil loss Equation RUSLE. are implemented and compared, one using slope length and the other using flow ac

Estimating surface flow over digital elevation models using a new improved form-based algorithm

This paper discusses new improvements of a form-based algorithm, which is used to estimate flow distribution over a continuous surface. In the new form- based algorithm (IFBFD), cells in a DEM are classified into five different classes. The classes are Peaks, Complicated, Sinks, Flats and Undisturbed cells. The method of how to estimate the flow distribution from each cell depends on its class. Es

Estimating slope from raster data : A test of eight different algorithms in flat, undulating and steep terrain

Eight frequently used slope algorithms based on a DEM (Digital Elevation Model) have been compared in flat, gently sloping/undulating, and steep terrain in order to investigate differences in estimated results. The matter of scale/resolution has not been considered, and the focus has not been on comparing the estimates with "ground truth" data but on comparisons between the different algorithms. P

Restoring Degraded Lands

Land degradation continues to be an enormous challenge to human societies, reducing food security, emitting greenhouse gases and aerosols, driving the loss of biodiversity, polluting water, and undermining a wide range of ecosystem services beyond food supply and water and climate regulation. Climate change will exacerbate several degradation processes. Investment in diverse restoration efforts, i

Difference in Performance of EPI Pigs Fed Either Lipase-Predigested or Creon®-Supplemented Semielemental Diet

Pancreatic enzyme replacement therapy (PERT) and fat predigestion are key in ensuring the optimal growth of patients with cystic fibrosis. Our study attempted to highlight differences between fat predigestion and conventional PERT on body composition of young pigs with exocrine pancreatic insufficiency (EPI). EPI and healthy pigs were fed with high-fat diet for six weeks. During the last two weeks

Is cadmium a risk factor for breast cancer - Results from a nested case-control study using data from the malmö diet and cancer study

Background: Some studies have shown that cadmium (Cd) is associated with breast cancer risk. One hypothesis is that Cd has estrogen-like properties. This case-control study investigated the association between breast cancer risk and blood Cd (BCd) levels. Methods: All breast cancers in the Malmö Diet and Cancer cohort were identified through linkage to the Swedish Cancer Registry, baseline (1991-1

Immune infiltrate in the primary tumor predicts effect of adjuvant radiotherapy in breast cancer : Results from the randomized SweBCG91RT trial

Purpose: Tumor-infiltrating immune cells play a key role in tumor progression. The purpose of this study was to analyze whether the immune infiltrate predicts benefit from postoperative radiotherapy in a large randomized breast cancer radiotherapy trial. Experimental Design: In the SweBCG91RT trial, patients with stage I and II breast cancer were randomized to breast-conserving surgery (BCS) and p

PSA-Targeted Alpha-, Beta-, and Positron-emitting immunotheranostics in murine prostate cancer models and nonhuman primates

Purpose: Most patients with prostate cancer treated with androgen receptor (AR) signaling inhibitors develop therapeutic resistance due to restoration of AR functionality. Thus, there is a critical need for novel treatment approaches. Here we investigate the theranostic potential of hu5A10, a humanized mAb specifically targeting free PSA (KLK3). Experimental Design: LNCaP-AR (LNCaP with overexpres

Hypoxic induction of exosome uptake through proteoglycan-dependent endocytosis fuels the lipid droplet phenotype in Glioma

As an adaptive response to hypoxic stress, aggressive tumors rewire their metabolic phenotype into increased malignant behavior through extracellular lipid scavenging and storage in lipid droplets (LD). However, the underlying mechanisms and potential lipid source retrieved in the hypoxic tumor microenvironment remain poorly understood. Here, we show that exosome-like extracellular vesicles (EV),
