Parasitter og cytokiner i en naturlig populasjon I naturen finner vi utallige eksempler på arter som har spesialisert seg på å utnytte andre arter for næring, trygghet og overlevelse. Denne spesialiseringen kalles parasitisme, og har ofte en kostnad for verten i form av redusert helse og livskvalitet. Hos däggdjur, er en stor parasittgruppe innvollsparasitter. nematoder som lever i tarmene og sugAbstract In nature, the coexistence of parasites and hosts has been an important factor in evolution of the immune system, which can be found in all plants and animals. As parasitic infections are by definition affect overall fitness of the host, it is important for the host to be able to counteract the detrimental effects of infections. To ensure this, signaling molecules, known as cytokines, e

Molecular cluster is a nanoparticle that is defined as an agglomerate of few up to 106-7 of molecules (corresponding to 1- 100 nm in size) that can be manipulated by the cluster beams. Molecular cluster properties typically lie between the individual molecule and bulk matter properties. This work describes the employment of the Cold Aerodynamic Source (CAS) to produce a narrow, collimated and iso

Current genetic research on obsessive-compulsive disorder (OCD) supports contributions to risk specifically from common single nucleotide variants (SNVs), along with rare coding SNVs and small insertion-deletions (indels). The contribution to OCD risk from rare copy number variants (CNVs), however, has not been formally assessed at a similar scale. Here we describe an analysis of rare CNVs called

Apolipoprotein A-I (ApoA-I), the primary component of high-density lipoprotein (HDL) cholesterol primes β-cells to increase insulin secretion, however, the mechanisms involved are not fully defined. Here, we aimed to confirm ApoA-I receptors in β-cells and delineate ApoA-I-receptor pathways in β-cell insulin output. An LRC-TriCEPS experiment was performed using the INS-1E rat β-cell model and ApoA

CD59 is a cell-surface inhibitor of the terminal step in the complement cascade. However, in addition to its complement inhibitory function, a non-canonical role of CD59 in pancreatic beta cells has been identified. Two recently discovered intracellular alternative splice forms of CD59, IRIS-1 and IRIS-2, are involved in insulin exocytosis through interactions with SNARE-complex components. In mic

Objectives To study informed consent to midwifery practices and interventions during the second stage of labor and to investigate the association between informed consent and experiences of these practices and interventions and women's experiences of the second stage of labor. Methods This study uses an observational design with data from a follow-up questionnaire sent to women one month after giv

High latitude mires are key ecosystems in the context of climate change since they store large amounts of carbon while constituting an important natural source of methane (CH4). However, while a growing number of studies have investigated methane fluxes (FCH4) at the plot- (~1 m2) and ecosystem-scale (~0.1–0.5 km2) across the boreal biome, variations of FCH4 magnitudes and drivers at the mesoscale

BACKGROUND: Screening immigrant mothers for postpartum depression has been shown to be challenging for health care professionals in handling cultural implications of postpartum depression, communicating through interpreter and applying translated versions of the screening scale.AIM: The aim of the study was to test the feasibility of an evidence-based educational intervention for Child Health Serv

The boreal forest landscape covers approximately 10% of the earth's land area and accounts for almost 30 % of the global annual terrestrial sink of carbon (C). Increased emissions due to climate-change-amplified fire frequency, size, and intensity threaten to remove elements such as C and nitrogen (N) from forest soil and vegetation at rates faster than they accumulate. This may result in large ar

Background: A majority of patients with end-stage renal disease suffer from secondary hyperparathyroidism, which is associated with osteoporosis and cardiovascular disease. Parathyroidectomy (PTX) is often necessary despite medical treatment. However, the effect of PTX on cardio- and cerebrovascular events (CVE) remains unclear. Data on the effect of PTX from population-based studies are scarce. S

Climate warming is driving changes in species distribution, but habitat characteristics can interact with warming temperatures to affect populations in unexpected ways. We investigated wintering waterbird responses to climate warming depending on habitat characteristics, with a focus on the northern boundary of their non-breeding distributions where winter climatic conditions are more extreme. At

Overweight and obesity rates have increased in recent decades, particularly among the younger population. The long-term consequences of obesity with respect to early venous thromboembolism (VTE) in women have not been established. The aim was to investigate the association between body mass index (BMI) in early pregnancy as a proxy for non-pregnant weight and long-term post-pregnancy risk of VTE i

Parkinson's disease (PD) is characterized by dopaminergic neurodegeneration, α-Synuclein (α-Syn) pathology, and inflammation. Microglia in the substantia nigra pars compacta (SNpc) upregulate major histocompatibility complex class II (MHCII), and variants in genes encoding MHCII affect PD risk. Additionally, elevated TNF levels and α-Syn-reactive T cells in circulation suggest a strong link betwee

Low birthweight is a risk factor for type 2 diabetes. We hypothesised that differential associations between birthweight and clinical characteristics in persons with and without type 2 diabetes may provide novel insights into the role of birthweight in type 2 diabetes and its progression. We analysed UK Biobank data from 9,442 persons with and 254,446 without type 2 diabetes. Associations between

Introduction In type 2 diabetes (T2D), beta cell failure is often associated with islet inflammation driven by the innate immune response, with macrophages playing a significant role. However, the composition and phenotype of lymphoid immune cells in the islets of individuals with T2D have not been extensively studied. This study aims to characterize and compare the presence, phenotype, and freque

TAR DNA-binding protein 43 (TDP-43) pathology is linked to the neurodegenerative disorders amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD) and Huntington disease (HD). Dysregulation of metabolism and emotion is shared across these disorders and may be caused by hypothalamic pathology. Inclusions with TDP-43 are present in the hypothalamus in clinical ALS, as well as selective lo

BACKGROUND: Mental health service users often experience difficulties interpreting and regulating sensory stimuli resulting in increased anxiety, decreased abilities to engage in activities and a hampered recovery process. However, there are limited studies on the implementation of such recovery-oriented interventions targeting sensory difficulties via sensory modulation techniques. Therefore, the
