Tidal stripping as a mechanism for placing globular clusters on wide orbits : The case of MGC1 in M31

The globular clusters of large spiral galaxies can be divided into two populations: one that formed in situ and one that comprises clusters tidally stripped away from other galaxies. In this paper, we investigate the contribution to the outer globular cluster population in the M31 galaxy through donation of clusters from dwarf galaxies. We test this numerically by comparing the contribution of glo

Autoantibodies common in patients with gastrointestinal diseases are not found in patients with endometriosis : A cross-sectional study

Objectives: Gastrointestinal symptoms are common in endometriosis, but the mechanisms behind these symptoms are yet poorly understood. Associations between endometriosis and irritable bowel syndrome (IBS), celiac disease, and various autoimmune diseases have been reported. These diseases express characteristic autoantibodies. The aim of the current study was to investigate autoantibodies against g

Paralinguistic Information and Biological Codes in Intra- and Interspecific Vocal Communication: A pilot study of Humans and Domestic Cats

This pilot study is an attempt to explore how fundamental frequency (f0) as an acoustic correlate to paralinguistic infor- mation and biological codes are em- ployed in interspecific vocal communi- cation. Measures of f0 in human (Homo sapiens) and domestic cat (Felis catus) intra- and interspecific communication were compared. Results showed higher mean f0 in interspecific than intraspe- cific ut

Early microgliosis precedes neuronal loss and behavioural impairment in mice with a frontotemporal dementia-causing CHMP2B mutation

Frontotemporal dementia (FTD)-causing mutations in the CHMP2B gene lead to the generation of mutant C-terminally truncated CHMP2B. We report that transgenic mice expressing endogenous levels of mutant CHMP2B developed late-onset brain volume loss associated with frank neuronal loss and FTD-like changes in social behaviour. These data are the first to show neurodegeneration in mice expressing mutan

Derivation and validation of the CREST model for very early prediction of circulatory etiology death in patients without ST-segment-elevation myocardial infarction after cardiac arrest

BACKGROUND: No practical tool quantitates the risk of circulatory-etiology death (CED) immediately after successful cardiopulmonary resuscitation in patients without ST-segment-elevation myocardial infarction. We developed and validated a prediction model to rapidly determine that risk and facilitate triage to individualized treatment pathways. METHODS: With the use of INTCAR (International Cardia

Which ante mortem clinical features predict progressive supranuclear palsy pathology?

Background: Progressive supranuclear palsy (PSP) is a neuropathologically defined disease presenting with a broad spectrum of clinical phenotypes. Objective: To identify clinical features and investigations that predict or exclude PSP pathology during life, aiming at an optimization of the clinical diagnostic criteria for PSP. Methods: We performed a systematic review of the literature published s

TMEM106B and ApoE polymorphisms in CHMP2B-mediated frontotemporal dementia (FTD-3)

Single-nucleotide polymorphisms in the TMEM106B gene have been identified as a risk factor in frontotemporal dementia (FTD). The major allele of SNP rs3173615 is a risk factor in sporadic FTD, whereas the minor allele seems protective in GRN- and C9orf72-mediated FTD. The role of apolipoprotein E (ApoE) in FTD is uncertain, though an established risk factor in Alzheimer's disease. In a unique Dani

Return to Work and Participation in Society after Out-of-Hospital Cardiac Arrest

Background: The aim of this study was to describe out-of-hospital cardiac arrest (OHCA) survivors' ability to participate in activities of everyday life and society, including return to work. The specific aim was to evaluate potential effects of cognitive impairment. Methods and Results: Two hundred eighty-seven OHCA survivors included in the TTM trial (Target Temperature Management) and 119 match

Spatio-temporal activation of caspase-8 in myeloid cells upon ischemic stroke

Ischemic stroke (caused by thrombosis, embolism or vasoconstriction) lead to the recruitment and activation of immune cells including resident microglia and infiltrating peripheral macrophages, which contribute to an inflammatory response involved in regulation of the neuronal damage. We showed earlier that upon pro-inflammatory stimuli, the orderly activation of caspase-8 and caspase-3/7 regulate

A methodological study of locus coeruleus degeneration in dementing disorders

Background: Degeneration of the locus coeruleus (LC) of the brain stem is a recognized phenomenon in Alzheimer's disease (AD), in dementia with Lewy bodies (DLB), and in Parkinson's disease with dementia (PDD). Prior studies have suggested that LC degeneration can be used to differentiate various dementing disorders histologically, but the paucity of methodological data may hamper systematic resea
