Age-related macular degeneration (AMD) is a degenerative disease of the retina and a leading cause of irreversible vision loss. We investigated the systemic differences in the frequency of T helper (Th) 1 and Th17 cells in patients with non-exudative and exudative AMD and compared to age-matched controls. Flow cytometry was used to determine the systemic frequency of Th1 (CD4+CXCR3+IL12RB2+) and T
Age-related macular degeneration (AMD) has been associated with both systemic and ocular alterations of the immune system. In particular dysfunction of complement factor H (CFH), a soluble regulator of the alternative pathway of the complement system, has been implicated in AMD pathogenesis. One of the ligands for CFH is long pentraxin 3 (PTX3), which is produced locally in the retinal pigment epi
It is considered unavoidable that there is some variation in how different fire services assess matters in the building process. However, it is unclear how great this variation is. A large variation can be problematic because it can result in that different municipalities make different demands on similar projects. The purpose of this work is to investigate how large this variation can be with a R
PURPOSE: The chemokine receptors CX3CR1 and CCR2 have been implicated in the development of age-related macular degeneration (AMD). The evidence is mainly derived from experimental cell studies and murine models of AMD. The purpose of this study was to investigate the association between expression of CX3CR1 and CCR2 on different leukocyte subsets and AMD. Furthermore we measured the plasma levels
PURPOSE: We have recently identified homeostatic alterations in the circulating T cells of patients with age-related macular degeneration (AMD). In cultures of retinal pigment epithelial cells, we have demonstrated that T-cell-derived cytokines induced the upregulation of complement, chemokines and other proteins implicated in AMD pathogenesis. The purpose of this study was to test whether increas
PURPOSE: The chemokine receptor CXCR3 has been strongly related to inhibition of angiogenesis. The purpose of this study was to investigate the association between expression of CXCR3 on peripheral blood leukocytes and age-related wet macular degeneration. Furthermore, we measured the plasma concentration of chemokines CXCL9 to -11.METHODS: The study group consisted of patients with age-related ma
Age-related macular degeneration (AMD) is a leading cause of visual impairment in the aged population worldwide. The mechanisms underlying this multifactorial and heterogenic disease are complex and incompletely understood. There is increasing evidence to suggest that regulatory differences in the immune system are involved in the development of the various subtypes of AMD. The purpose of this the
OBJECTIVES: To evaluate potential differences in plasma 25-hydroxyvitamin in subtypes of age-related macular degeneration (AMD), and in patients in Clinical Age-Related Maculopathy Staging (CARMS) group 5 with or without subretinal fibrosis.METHODS: This single-center cross-sectional study included 178 participants during a period of 20 months. Ninety-five patients belonged to CARMS 5; twelve belo
BACKGROUND: Dysregulation of the CCR3/CCL11 pathway has been implicated in the pathogenesis of choroidal neovascularisation, a common feature of late age-related macular degeneration (AMD). The aim of this study was to investigate the expression of CCR3 and its ligand CCL11 in peripheral blood in patients with neovascular AMD.METHODS: Patients with neovascular AMD and healthy controls were include
PURPOSE: To investigate the expression of the complement regulatory proteins CD46, CD55, and CD59 on peripheral leukocytes in neovascular age-related macular degeneration (AMD).DESIGN: Prospective, case-control study.METHODS: Thirty-five unrelated patients with neovascular AMD and 30 control individuals were included in this case-control study. All participants were subjected to a structured inter
PURPOSE: Association of neovascular age-related macular degeneration (AMD) with C-reactive protein (CRP) was previously reported, indicating a relation to systemic low-grade inflammation. However, visual impairment limits physical activity, and physical activity modulates CRP levels. Here, we investigated the impact of physical activity on CRP levels in patients with neovascular AMD and control in
OBJECTIVE: Dysregulation of retinal microglial activity has been implicated in the pathogenesis of neovascular age-related macular degeneration. Microglia activity can be regulated through the membrane protein CD200 and its corresponding receptor, the CD200 receptor (CD200R). Because both the ligand and the receptor are expressed on a broad spectrum of cell types, we set out to study the expressio
PURPOSE: To examine the association between age-related changes in the T-cell compartment and prevalence of age-related macular degeneration (AMD).DESIGN: Case-control study.PARTICIPANTS: A total of 117 AMD cases and 106 controls were included prospectively.METHODS: Fresh-drawn peripheral blood samples were processed for flow cytometric analysis of T-cell populations. Plasma samples were analyzed
PURPOSE: To investigate corneal endothelial cell density and morphology in type II diabetic and non-diabetic patients and to relate potential differences to the glycaemic status.METHODS: A prospective clinical study including 107 patients with type II diabetes and 128 non-diabetic patients. Sample size was based on a power calculation (power = 0.90; p = 0.05). The diabetic patients had on average
Cognitive linguistic and semiotic accounts of metaphor have addressed similar issues such as universality, conventionality, context-sensitivity, cross-cultural variation, creativity, and “multimodality.” However, cognitive linguistics and semiotics have been poor bedfellows and interactions between them have often resulted in cross-talk. This paper, which focuses on metaphors in Greek street art,
Determining the drivers of diversity is a major topic in biology. Due to its high level of micro-endemism in many taxa, Madagascar has been described as one of Earth's biodiversity hotspot. The exceptional Malagasy biodiversity has been shown to be the result of various eco-evolutionary mechanisms that have taken place on this large island since its isolation from other landmasses. Extensive phylo
There is a scarcity of instruments for assessing opportunities for residentswith psychiatric disabilities to engage in meaningful home-based activities.We thus developed the Perceived Meaning of Activity in Housing (PMA-H),containing four subscales (activity opportunities, social interaction, developingas a person, and organization and planning). The aim of the study was to investigate the content
