Telomere Biology and Vascular Aging

Telomeres form the end segment of the DNA helix and shorten with every cell division until getting so short that the cell stops dividing and will undergo programmed cell death (apoptosis). Research has supported the view that telomere length could be regarded as a marker of biological aging, even if methodological problems could interfere with the interpretation of telomere length in cross-section

CPAP and health-related quality of life in adults with coronary artery disease and nonsleepy obstructive sleep apnea in the RICCADSA trial

Study Objectives: To determine the effect of continuous positive airway pressure (CPAP) treatment on health-related quality of life (HRQoL) in adults with coronary artery disease (CAD) and nonsleepy obstructive sleep apnea (OSA). Methods: This was a secondary outcome analysis of the RICCADSA trial, conducted in Sweden between 2005 and 2013. Adults with CAD, nonsleepy OSA (apnea-hypopnea index [AHI

Hip-related groin pain, patient characteristics and patient-reported outcomes in patients referred to tertiary care due to longstanding hip and groin pain : A cross-sectional study

Background: Due to advances in hip arthroscopy, the number of surgical procedures has increased dramatically. The diagnostic challenge in patients with longstanding hip and groin pain, as well as the increasing number of hip arthroscopies, may lead to a higher number of patients referred to tertiary care for consideration for surgery. Therefore, the aims were: 1) to describe the prevalence of hip-

Aging Population : Challenges and Opportunities in a Life Course Perspective

In most Western countries the mean longevity for both men and women has increased dramatically over the past 100 years. This was first attributable to a reduction in perinatal and child mortality when deliveries became safer and conditions for children more healthy, such as better nutrition. In recent decades another trend is visible, that is, a reduction of the negative impact of chronic disease

Early Vascular Aging in the Young : Influence of Birth Weight and Prematurity

Longitudinal data from cohort studies show that early life factors such as low birth weight are associated with the development of hypertension, coronary heart disease, and type 2 diabetes in adulthood. Moreover, the majority of published studies concur that blood pressure is higher in adolescents and young adults with a history of low birth weight. Although the precise mechanisms linking early li

Entrepreneurship as a Career : An investigation into the pre-entrepreneurship antecedents and post-entrepreneurship outcomes among the Science and Technology Labor Force (STLF) in Sweden

This dissertation provides a career perspective on entrepreneurship based on the research question: “How do organizational bureaucracy and relative income affect the career choice of entrepreneurship among employees from the science and technology labor force (STLF); and what are the career outcomes in terms of returns during, and post entrepreneurship on re-entry into paid employment?” More speci

Early Vascular Aging (EVA) : New directions in cardiovascular protection

Early Vascular Aging (EVA): New Directions in Cardiovascular Protection brings together the last decade of research related to the characterization of EVA, as well as the predictive power of pulse wave velocity (PWV). The book presents a novel approach to the problem of cardiovascular disease, showing it in relation to great vessels disease and revealing a comprehensive approach to the problem of

Endo-lysosomal proteins and ubiquitin CSF concentrations in Alzheimer's and Parkinson's disease

Background: Increasing evidence implicates dysfunctional proteostasis and the involvement of the autophagic and endo-lysosomal system and the ubiquitin-proteasome system in neurodegenerative diseases. In Alzheimer's disease (AD), there is an accumulation of autophagic vacuoles within the neurons. In Parkinson's disease (PD), susceptibility has been linked to genes encoding proteins involved in aut

A comprehensive assessment of demographic, environmental, and host genetic associations with gut microbiome diversity in healthy individuals

BACKGROUND: The gut microbiome is an important determinant of human health. Its composition has been shown to be influenced by multiple environmental factors and likely by host genetic variation. In the framework of the Milieu Intérieur Consortium, a total of 1000 healthy individuals of western European ancestry, with a 1:1 sex ratio and evenly stratified across five decades of life (age 20-69), w

Highlighting the Dynamics of Graphene Protection toward the Oxidation of Copper under Operando Conditions

We performed spatially resolved near-ambient-pressure photoemission spectromicroscopy on graphene-coated copper in operando under oxidation conditions in an oxygen atmosphere (0.1 mbar). We investigated regions with bare copper and areas covered with mono- and bi-layer graphene flakes, in isobaric and isothermal experiments. The key method in this work is the combination of spatial and chemical re

Discordant amyloid-β PET and CSF biomarkers and its clinical consequences

Background: In vivo, high cerebral amyloid-β load has been associated with (i) reduced concentrations of Aβ42 in cerebrospinal fluid and (ii) increased retention using amyloid-β positron emission tomography. Although these two amyloid-β biomarkers generally show good correspondence, ~ 10-20% of cases have discordant results. To assess the consequences of having discordant amyloid-β PET and CSF bio

Lawrence Summers Deserves a Nobel Prize for Reviving the Theory of Secular Stagnation

Lawrence Summers produced a big upset within the economics profession when he revived Alvin Hansen’s theory of secular stagnation, which had been thought of as an old-Keynesian fallacy. While some economists like Brad DeLong and Paul Krugman instantly recognized Summers’s contribution, a large share of the economics profession remained skeptical at first. Whereas most New Keynesian models allow fo

Conversion of xylan into value-added products

Today’s high demand on finding sustainable energy sources, replacing petroleum-based products and the needfor healthier food alternatives have forced us to search for natural recoverable resources and explore their manyhidden applications. One such resource is xylan, which has gained much attention as possible raw material forvarious exploitations. However, its wider industrial application puts de

The Molecular Chaperone DNAJB6, but Not DNAJB1, Suppresses the Seeded Aggregation of Alpha-Synuclein in Cells

Alpha-synuclein (α-Syn) can misfold and aggregate, causing the degeneration of dopaminergic neurons, as seen in Parkinson's disease (PD). We recently demonstrated that DNAJB6, a co-chaperone found in Lewy bodies (LB), suppresses the aggregation of α-Syn in cells and in vitro. In this study, we compared the capacities of DNAJB1 and DNAJB6 to suppress the seeded α-Syn aggregation in HEK293 cells exp

Efficacy of Lactobacillus rhamnosus GG in treatment of acute pediatric diarrhea : A systematic review with meta-analysis

BACKGROUND Diarrhea is a major infectious cause of childhood morbidity and mortality worldwide. In clinical trials, Lactobacillus rhamnosus GG ATCC 53013 (LGG) has been used to treat diarrhea. However, recent randomized controlled trials (RCTs) found no evidence of a beneficial effect of LGG treatment. AIM To evaluate the efficacy of LGG in treating acute diarrhea in children. METHODS The EMBASE,

Decrease of soil organic matter stabilization with increasing inputs : Mechanisms and controls

Crop residue addition is a way to increase soil organic matter (SOM) level in croplands. However, organic matter input and SOM stocks are not linearly related. Consequently, adding high amounts of residues, such as straw, may increase SOM to only a small extent, and an alternative use of the residues may be justified. The objective of this study was to test how the level and type (above- or belowg

Integrated effect of different N-fertilizer rates and bioslurry application on growth and N-use efficiency of okra (Hibiscus esculentus L.)

Bioslurry obtained from biogas plants has the potential to reduce the use of expensive chemical fertilizers and increase yields. A field experiment was conducted to investigate the growth response and yield production of okra fertilized with various combinations of bioslurry and nitrogen fertilizer. The experiment was planned according to randomized complete block design with 3 replications. Biosl
