Vacuum impregnation (VI) has been widely utilized as a pre-treatment method prior to, e.g., the minimal processing, freezing, or drying of foods. In many cases, VI has been used to focus on the enrichment of fruits and vegetables with probiotics or micronutrients, texture enhancement, the modification of the sensory attributes, and extension of shelf life by pH reduction. However, little attention
Background In this study, the long term effects of ECT on patients with depression were investigated through repeated rCBF and EEG measures as well as clinical characteristics over several years. The aim of the investigation was to establish an association with the eventual development of dementia. Method A cohort of forty-nine patients (21 men and 28 women) with a mean age of 61 years underwent E
Vacuum impregnation is used in the food industry to facilitate the impregnation of porous products with, e.g. firming, antioxidant, antimicrobial or cryoprotective agents. X-ray micro-tomography (μCT) was used to study the process of vacuum impregnation in spinach leaves. Low (300 mbar absolute pressure) and mild vacuum (150 mbar absolute pressure) impregnation protocols were used to impregnate an
This study compares the time required to activate a grasp or function of a hand prosthesis when using an electromyogram (EMG) based control scheme and when using a control scheme combining EMG and control signals from an inductive tongue control system (ITCS). Using a cross-over study design, 10 able-bodied subjects used a computer model of a hand and completed simulated grasping exercises. The ti
The role of dendritic cells (DCs) in intestinal immune homeostasis remains incompletely defined. Here we show that mice lacking IRF8 transcription-factor-dependent DCs had reduced numbers of T cells in the small intestine (SI), but not large intestine (LI), including an almost complete absence of SI CD8αβ+ and CD4+CD8αα+ T cells; the latter requiring β8 integrin expression by migratory IRF8 depend
Denna avhandling består av fyra delstudier som undersöker hur internetreklam påverkar barns visuella uppmärksamhet. Syftet med studierna var att ta reda på om barn distraherades av internetreklam när de interagerade med webbsidor med hjälp av en vanlig webbläsare. Varje delstudie undersökte hur en specifik uppsättning variabler och faktorer gemensamt bidrog till att predicera hur barnen betraktadeThis dissertation consists of four eye-tracking studies that investigate how salient online advertising and children's level of executive function contributes to their advert distraction. In Study 1, children aged 9 were instructed to surf freely on the internet while all advert material appearing on-screen was registered. The analyses examined how perceptual prominence in each online advert was r
Introduction There is a consensus that factors released by the placenta to maternal circulation, including TNF-α, play a key role in activating the maternal endothelium in pregnancies with preeclampsia (PE). Dual perfusion preserves the structural organization of the placenta to a greater degree than other in vitro systems and has been used by our group and others to examine placental pathophysiol
Vectoring enables cooperative crosstalk mitigation in wideband wireline systems. A sudden termination change within a vectored group alters the entire perceived channel matrix and thus disturbs the vectoring operation since the precoder, which is tuned to the channel before the change, is no longer up to date. We analyze the resulting residual crosstalk and its impact on performance degradation du
The severity of urinary tract infections (UTIs) varies depending on the balance between the virulence of the infecting bacterial strain and the antibacterial host defense. Bacterial virulence is determined by a complex of factors in which bacterial adherence to the uroepithelium is the most important virulence factor, in addition to the production of toxins and the formation of biofilm. In immunoc
BACKGROUND: The discovery of low-frequency coding variants affecting the risk of coronary artery disease has facilitated the identification of therapeutic targets. METHODS: Through DNA genotyping, we tested 54,003 coding-sequence variants covering 13,715 human genes in up to 72,868 patients with coronary artery disease and 120,770 controls who did not have coronary artery disease. Through DNA sequ
The genome is often the conduit through which environmental exposures convey their effects on health and disease. Whilst not all diseases act by directly perturbing the genome, the phenotypic responses are often genetically determined. Hence, whilst diseases are often defined has having differing degrees of genetic determination, genetic and environmental factors are, with few exceptions, insepara
Summary Background In Sweden, the most common causes of liver cirrhosis are alcohol overconsumption and hepatitis C. However, recent data on the clinical characteristics of Swedish patients with cirrhosis are scarce. Aims To determine the incidence, clinical presentation, aetiological spectrum and survival rates of liver cirrhosis in Southern Sweden from 2001 to 2011. Methods We used population-ba
Background: Although studies have shown associations between neighbourhood quality and chronic disease outcomes, such associations are potentially confounded by the selection of different types of people into different neighbourhood environments. We sought to identify the causal effects of neighbourhood deprivation on type 2 diabetes risk, by comparing refugees in Sweden who were actively disperse
We present a new SAH guided approach to subdividing triangles as the scene is coarsely partitioned into smaller sets of spatiallycoherent triangles. Our triangle split approach is integrated into the partitioning stage of a fast BVH construction algorithm, butmay as well be used as a stand alone pre-split pass. Our algorithm significantly reduces the number of split triangles comparedto previous m
OBJECTIVE:: In this study we aimed to investigate the frequency and activation of invariant natural killer T (iNKT) cells and natural killer (NK) cells among HIV-1, HIV-2, or dually HIV-1/HIV-2 (HIV-D)-infected individuals, in relation to markers of disease progression. DESIGN:: Whole blood samples were collected from treatment-naïve HIV-1 (n?=?23), HIV-2 (n?=?34) and HIV-D (n?=?11) infected indiv
Aims/hypothesis: Genome-wide association studies (GWAS) have identified more than 65 genetic loci associated with risk of type 2 diabetes. However, the contribution of distorted parental transmission of alleles to risk of type 2 diabetes has been mostly unexplored. Our goal was therefore to search for parent-of-origin effects (POE) among type 2 diabetes loci in families. Methods: Families from the
The article discusses possible effects of the use of analgesics during pregnancy. It summarizes the pertinent literature and reports some previously unpublished data from the Swedish Medical Birth Register. Most likely the use of analgesics does not cause spontaneous abortion. Only small malformation risk increases are seen after the use of opioids and perhaps non-steroid anti-inflammatory drug (N
