INTRODUCTION: A granular understanding of the mechanisms linking tau pathology to cognitive decline in Alzheimer's disease is crucial. We investigate mediating effects of medial temporal lobe (MTL) and neocortical neurodegeneration on tau-induced domain-specific cognitive impairment in amyloid-beta (Aβ) positive cognitively normal and impaired adults.METHODS: We assessed magnetic resonance imaging
The anterior portion of the medial temporal lobe (MTL) is one of the first regions targeted by pathology in sporadic Alzheimer's disease (AD) and limbic-predominant age-related TDP-43 encephalopathy (LATE) indicating a potential for metrics from this region to serve as imaging biomarkers. Leveraging a unique post-mortem dataset of histology and magnetic resonance imaging (MRI) scans, we aimed to (
Background: Data in Ethiopia on the epidemiology of Respiratory Syncytial Virus (RSV) and subtypes among influenza-like illness (ILI) and severe acute respiratory infections (SARI) cases is limited. Here, we assessed the epidemiology of RSV and its subtypes among the pediatric and adult ILI /SARI cases in Ethiopia. Methods: We conducted prospective, multicenter facility-based study from May 2023 t
Latency is a common strategy in a wide range of viral lineages, but its prevalence in giant viruses remains unknown. In this work, we describe a 617–kilo–base pairs integrated giant viral element in the model green alga Chlamydomonas reinhardtii. We resolved the integrated viral genome using long-read sequencing, identified a putative polintovirus-like integrase, and show that viral particles accu
The presence of a single attractive impurity in an ultracold repulsive bosonic system can drive a transition from a homogeneous to a localized state, as we here show for a one-dimensional ring system. In the few-body limit, the localization of the bosons around the impurity, as seen in the pair correlations, is accompanied by low-lying modes that resemble finite-sized precursors of Higgs-Anderson-
BACKGROUND: Atrial fibrillation (AF) is suggested to be associated with venous thromboembolism (VTE) and might thereby play a role in the development of chronic thromboembolic pulmonary hypertension (PH). By elevating left-sided filling pressure and promoting atrial myopathy, AF may also play a role in the development of postcapillary PH. We aimed to investigate the association between AF, with or
Effluent wastewater contains organic micropollutants (OMPs) that harm aquatic ecosystems. Therefore, wastewater treatment plants (WWTPs) need to expand their facilities with advanced water treatment technologies. Water scarcity and improved effluent quality is encouraging the reuse of treated effluent. This study thus has a dual purpose: first, to evaluate OMP removal using two technique combinati
Aging and aging-related neurodegenerative disorders, such as Alzheimer’s disease, are characterized by chronic inflammation that progressively damages nervous tissue within the central nervous system (CNS). In addition to cytokines, lectin-like carbohydrate recognition molecules play a critical role in modifying cellular communication during inflammation. Among these, galectins—particularly anti-i
In recent years, new contributors to the marine silica cycle have emerged, including pico-sized phytoplankton (<2–3 µm in size) such as Synechococcus and picoeukaryotes. Their contribution and relevance to silica cycling are still under investigation. Field studies reporting the biogenic silica (bSi) standing stock in the pico-sized fraction are limited to silica-poor oligotrophic environments, an
It is becoming clear that the cognition of a species plays an important role in successful conservation, with cultural processes being a fundamental part of this. However, in contrast to mammals and birds, very little is known about cultural processes (and the social learning that underlies these) in reptiles. Here, we summarize the current state of knowledge, consider why this information is so l
