The association between dietary intake, lifestyle and incident symptomatic peripheral arterial disease among individuals with diabetes mellitus : insights from the Malmö Diet and Cancer study

With the rising prevalence of both diabetes mellitus (DM) and peripheral arterial disease (PAD), the aim of this project was to examine the association between dietary intake and lifestyle on the risk of developing PAD among individuals with DM. The Malmö Diet and Cancer study was a prospective cohort study with baseline examinations carried out between 1991 and 1996 in Malmö, Sweden (n = 30,446).

Beta secretase 1-dependent amyloid precursor protein processing promotes excessive vascular sprouting through NOTCH3 signalling

Amyloid beta peptides (Aβ) proteins play a key role in vascular pathology in Alzheimer’s Disease (AD) including impairment of the blood–brain barrier and aberrant angiogenesis. Although previous work has demonstrated a pro-angiogenic role of Aβ, the exact mechanisms by which amyloid precursor protein (APP) processing and endothelial angiogenic signalling cascades interact in AD remain a largely un

Coenzyme Q10 decreases amyloid pathology and improves behavior in a transgenic mouse model of alzheimer's disease

Increased oxidative stress is implicated in the pathogenesis of Alzheimer's disease (AD). A large body of evidence suggests that mitochondrial dysfunction and increased reactive oxygen species occur prior to amyloid-β (Aβ) deposition. Coenzyme Q10 (CoQ10), a component of the mitochondrial electron transport chain, is well characterized as a neuroprotective antioxidant in animal models and human tr

Accumulation of cellular prion protein within dystrophic neurites of amyloid plaques in the Alzheimer's disease brain

Amyloid plaques, a well-known hallmark of Alzheimer's disease (AD), are formed by aggregated β-amyloid (Aβ). The cellular prion protein (PrPc) accumulates concomitantly with Aβ in amyloid plaques. One type of amyloid plaque, classified as a neuritic plaque, is composed of an amyloid core and surrounding dystrophic neurites. PrPc immunoreactivity reminiscent of dystrophic neurites is observed in ne

On being dependent on home mechanical ventilation : Depictions of patients' experiences over time

In this study, the authors describe the meanings of experiences of being dependent on a ventilator (HMV) and living at home as narrated by 13 people who had been using a ventilator via a mask or tracheostomy for half a year. The analyses revealed various movements across time toward the goal of using the ventilator successfully, and some narratives depicted suffering caused by care. The analyses a

Clinical group supervision in an intensive care unit : A space for relief, and for sharing emotions and experiences of care

Much has been written about models, aims and the concept of clinical group supervisional, although few studies are empirical or focus on intensive care. • The aim of the study was to illuminate the process and describe, using qualitative content analysis, the content of conversations carried out during the course of clinical group supervision sessions among Registered Nurses (RN) and enrolled nurs

Inner histopathologic changes and disproportionate zone volumes in foetal growth plates following gestational hypoglycaemia in rats

Maternal hypoglycaemia throughout gestation until gestation day (GD)20 delays foetal growth and skeletal development. While partially prevented by return to normoglycaemia after completed organogenesis (GD17), underlying mechanisms are not fully understood. Here, we investigated the pathogenesis of these changes and significance of maternal hypoglycaemia extending beyond organogenesis in non-diabe

Repeatability of pheromone emissions from individual female ermine moths Yponomeuta padellus and Yponomeuta rorellus

The repeatability of the composition of pheromone emitted by individual female moths (Yponomeuta) was determined by gas Chromatographic analysis. An improved technique for repeated collections of airborne volatiles from the same moth was developed. The procedure did not harm the females and allowed precise quantification of 0.05 ng of pheromone components in 30-min collections. Individual females

Intake of Lactiplantibacillus plantarum HEAL9 reduces the inflammatory markers soluble fractalkine and CD163 during acute stress : A randomized, double blind, placebo-controlled study

The intestine and the brain are connected via the brain-gut axis and the intestinal microbiota influences the immune activation and signaling molecules that are involved in the stress response. The aim of the study was to investigate if intake of the probiotic strain Lactiplantibacillus plantarum HEAL9 (LPHEAL9) for four weeks could counteract elevated cortisol and inflammation levels in subjects

The need of latent variables for modelling decision-making in evacuation simulations

Evacuation models generally tend to make over-simplifications in the representation of human behaviour in fire due to the difficulties to capture its complexity. This work shows how ‘new’ discrete choice model approaches allow overcoming this issue. A description of the existing state-of-the-art of discrete choice models is introduced to highlight the potential of those models. Three case studies

Erosion of planetesimals by gas flow

The first stages of planet formation take place in protoplanetary disks that are largely made up of gas. Understanding how the gas affects planetesimals in the protoplanetary disk is therefore essential. In this paper, we discuss whether or not gas flow can erode planetesimals. We estimated how much shear stress is exerted onto the planetesimal surface by the gas as a function of disk and planetes

Foreign demand for agricultural commodities drives virtual carbon exports from Cambodia

Rapid deforestation is a major sustainability challenge, partly as the loss of carbon sinks exacerbates global climate change. In Cambodia, more than 13% of the total land area has been contracted out to foreign and domestic agribusinesses in the form of economic land concessions, causing rapid large-scale land use change and deforestation. Additionally, the distant drivers of local and global env

Under-reported relationship: a comparative study of pharmaceutical industry and patient organisation payment disclosures in the UK (2012-2016)

Objectives To examine the under-reporting of pharmaceutical company payments to patient organisations by donors and recipients. Design Comparative descriptive analysis of payments disclosed on drug company and charity regulator websites. Setting UK. Participants 87 donors (drug companies) and 425 recipients (patient organisations) reporting payments in 2012-2016. Main outcome measures. Number and

Granzyme B-mediated damage of CD8+ T cells impairs graft-versus-tumor effect

Allogeneic hematopoietic cell transplantation is an established treatment for hematologic and other malignancies. Donor-derived immune cells can identify and attack host tumor cells, producing a graft-versus-tumor (GVT) effect that is crucial to the treatment. Using multiple tumor models and diverse donor-host combinations, we have studied the role of granzyme B (GzmB) in GVT effect. We first conf
