Tau pathology as determinant of changes in atrophy and cerebral blood flow : a multi-modal longitudinal imaging study

Purpose: Tau pathology is associated with concurrent atrophy and decreased cerebral blood flow (CBF) in Alzheimer’s disease (AD), but less is known about their temporal relationships. Our aim was therefore to investigate the association of concurrent and longitudinal tau PET with longitudinal changes in atrophy and relative CBF. Methods: We included 61 individuals from the Amsterdam Dementia Cohor

Habitat area and local habitat conditions outweigh fragmentation effects on insect communities in vineyards

Fragmentation of habitat, for example by intensive agricultural practices, can be detrimental to local biodiversity. However, it often remains unclear whether such biodiversity declines are caused by loss of habitat area or increased fragmentation, and how habitat quality factors into it. In our study system, vegetated vineyards are typically small, and isolated from one another, potentially limit

Long-term trajectories of non-native vegetation on islands globally

Human-mediated changes in island vegetation are, among others, largely caused by the introduction and establishment of non-native species. However, data on past changes in non-native plant species abundance that predate historical documentation and censuses are scarce. Islands are among the few places where we can track human arrival in natural systems allowing us to reveal changes in vegetation d

PM2.5 and Dementia in a Low Exposure Setting : The Influence of Odor Identification Ability and APOE

BACKGROUND: Growing evidence show that long term exposure to air pollution increases the risk of dementia. OBJECTIVE: The aim of this study was to investigate associations between PM2.5 exposure and dementia in a low exposure area, and to investigate the role of olfaction and the APOE ɛ4 allele in these associations. METHODS: Data were drawn from the Betula project, a longitudinal study on aging,

A hybrid approach to assess the structural impact of long noncoding RNA mutations uncovers key NEAT1 interactions in colorectal cancer

Long noncoding RNAs (lncRNAs) are emerging players in cancer and they entail potential as prognostic biomarkers or therapeutic targets. Earlier studies have identified somatic mutations in lncRNAs that are associated with tumor relapse after therapy, but the underlying mechanisms behind these associations remain unknown. Given the relevance of secondary structure for the function of some lncRNAs,

Coordination of courses in university programmes and students’ experiences of their studies : student perspectives on the importance of course coordination

This article examines how university students assess the coordination of the courses their programmes contain and how course coordination affects how content they are with their studies. The study is based on survey data from more than 5700 students, collected through Lund University’s Student Barometer. The survey examines the students’ views on course coordination based on content, workload, adm

Hur kan det svenska skattesystemet bli mer konkurrenskraftigt?

Det svenska skattesystemet står inför en rad utmaningar, både inhemska ochinternationella, och behöver reformeras för att möta dessa. Mycket har häntsedan århundradets skattereform i början av 1990-talet när det gäller såvälden värld vi lever i som förändringar i skattesystemet och kunskapen kringskatters effekter på beteende. För att Sverige ska vara konkurrenskraftigt ochkunna vidmakthålla en hö

Associations between dietary patterns and dementia-related neuroimaging markers

BACKGROUND: The exploration of associations between dietary patterns and dementia-related neuroimaging markers can provide insights on food combinations that may impact brain integrity. METHODS: Data were derived from the Swedish Gothenburg H70 Birth Cohort Study (n = 610). Three dietary patterns were obtained using principal component analysis. Magnetic resonance imaging markers included cortical

Outpatient vs inpatient induction of labor with oral misoprostol : A retrospective study

Introduction: Induction of labor is one of the most common obstetrical procedures today, with a successively rising rate. With a limited number of hospital beds, the option of starting induction at home has gained increasing attention. The primary aim of this study was to compare the proportion of women achieving vaginal delivery and the duration of hospital stay before delivery in induction of la

This document details the main economic benefits of the blue economy of Ibiza and Formentera (Henceforth the “Pitiusas”). The main ecosystem services that the marine environment provides on both islands are identified, and the economic benefits estimated. The final objective of this study is to support the design of a sustainable blue economy strategy in the islands, in line with the Agenda 2030 a
