INTRODUCTION: It is hypothesized that cerebral hypoperfusion promotes the development of Alzheimer pathology. We therefore studied whether longstanding cerebral hypoperfusion is associated with Alzheimer pathology in nondemented humans.METHODS: Cerebral blood flow and amyloid β ((18)F-Flutemetamol) positron emission tomography retention were assessed in eleven patients with unilateral occlusion of
Abstract: Sexual dimorphism in somatic investment may be shaped by two distinct forms of sexual conflict; under intralocus sexual conflict (IASC), males and females have different optimal levels of somatic investment but are constrained from reaching their respective optima by their shared genome, while under interlocus sexual conflict (IRSC), males and females have different optimal sexual strate
Based on interviews with three generations of professors reflecting upon their development as early career researchers in an outstanding research environment within the STEMfield, this study aimed to explore how they had coped with relationship conflicts in the environment, how this had an impact on their team socialisation, and how their development was framed by their supervisors’ leadership. Us
Cerebellar dysfunction is commonly observed following traumatic brain injury (TBI). While direct impact to the cerebellum by TBI is rare, cerebellar pathology may be caused by indirect injury via cortico-cerebellar pathways. To address the hypothesis that degeneration of Purkinje cells (PCs), which constitute the sole output from the cerebellum, is linked to long-range axonal injury and demyelinat
Reactive oxygen species (ROS) are implicated in epithelial cell-state transition and deposition of extracellular matrix upon airway injury. Of the many cellular targets of ROS, oxidative DNA modification is a major driving signal. However, the role of oxidative DNA damage in modulation profibrotic processes has not been fully delineated. Herein, we report that oxidative DNA base lesions, 8-oxoG, c
OBJECTIVE: Elevated leukocyte count is a classic marker of systemic inflammation. This study examined whether the leukocyte count is associated with incidence of coronary events (CE) and stroke during a long follow-up period. METHODS: A total of 17,131 men and 2932 women, aged 27-61 years, without history of cardiovascular disease (CVD), were enrolled. Incidence of CE and stroke was studied in rel
This article explores the environmental impact of logistics service provider (LPS) activities in the light of increased customer priorities and the fragmentation of the industry. The research is based on a narrative literature review, an interview study, a case survey, and three in-depth case studies. A framework on sustainability challenges in supply chains derived from the literature is used to
A humoral immune response against aberrant tumor proteins can be elicited in cancer patients, resulting in the production of auto-antibodies (Abs). By serological proteome analysis we identified the surface membrane protein ADAM10, a metalloproteinase that has a role in epithelial-tumor progression and invasion, as a target of the immune response in colorectal cancer (Crc). A screening carried out
PURPOSE: Isoform-specific tumor estrogen receptor β (ERβ) expression may hold prognostic information in breast cancer, especially among endocrine-treated breast cancer patients. The study's purpose was to evaluate ERβ isoform 1 (ERβ1) expression in relation to tumor characteristics, ESR2 genotypes, and prognosis in different treatment groups.EXPERIMENTAL DESIGN: A population-based prospective coho
Introduction: The relationship between left ventricular (LV) ejection fraction (EF) and LV myocardial scar can identify potentially reversible causes of LV dysfunction. Left bundle branch block (LBBB) alters the electrical and mechanical activation of the LV. We hypothesized that the relationship between LVEF and scar extent is different in LBBB compared to controls. Methods: We compared the relat
BACKGROUND: Falls and related injuries are common among older people, and several drug classes are considered to increase fall risk.AIMS: This study aimed to investigate the association between the use of certain drug classes and falls in older nursing home residents in Sweden, and relate these to different age groups.METHODS: Information on falls that occurred in the previous year and regular use
Background: The role of B-lymphocytes in solid tumours is unclear. Tumour biology studies have implied both anti- and pro-tumoural effects and prognostic studies have mainly linked B-cells to increased survival. This study aimed to analyse the clinical relevance of B-lymphocytes in renal cell cancer (RCC), where information on the prognostic impact is lacking. Methods: Following immunohistochemist
INTRODUCTION: Patients with depression have significantly increased mortality from somatic disease. The purpose of this article was to review studies that investigate if there is a prognostic association with depression as co-morbidity in patients with chronic obstructive pulmonary disease (COPD). We chose the following outcomes: mortality, suicide behaviour, risk of COPD exacerbation, use of prim
Levodopa is a precursor to dopamine that has been shown to improve functional recovery following stroke partly achieved through mechanisms of brain plasticity. This study investigates if dopamine might affect plasticity by having a direct effect on synaptic plasticity through alterations in neurotransmitter release and re-uptake. Synaptogyrin is a synaptic vesicle protein that has been suggested t
Plants respond to insect infestation with defenses targeting insect eggs on their leaves and the feeding insects. Upon perceiving cues indicating imminent herbivory, such as damage-induced leaf odors emitted by neighboring plants, they are able to prime their defenses against feeding insects. Yet it remains unknown whether plants can amplify their defenses against insect eggs by responding to cues
Complement is a key first line innate host defense system in the blood of vertebrates. Upon activation, this powerful defense mechanism can elicit inflammatory responses, lyse non-self-cells, or mark them for opsonophagocytic removal. Blood-feeding arthropods thus require the ability to block host complement activation in the bloodmeal to prevent undesired cell or tissue damage during feeding. The
Recordings of the firing rates of single antennal neurons when Agrotis segetum antennac were placed 70 cm downwind of a pheromone source revealed that cells sensitive to the most volatile component adapted rapidly in a plume from a high-concentration source known from previous studies to cause in-flight arrestment of progress towards the source. No adaptation was found in response to lower-concent
