One strategy evolved by teeth to avoid irreversible damage is to move and deform under the loads incurred during mastication. A key component in this regard is the periodontal ligament (PDL). The role of the bone underlying the PDL is less well defined. We study the interplay between the PDL and the underlying alveolar bone when loaded in the minipig. Using an Instron loading device we confirmed t

Objectives: To study the risk of osteoporosis-related fractures in a community-based sample of men and women with rheumatoid arthritis (RA) overall, as well as early (< 1 year of disease duration, follow-up time maximum 10 years) and established (RA diagnosis since ≥ 5 years on July 1, 1997) RA, compared with the general population. To study potential risk factors for fractures in patients with RA

OBJECTIVE: To investigate the feasibility of synchrotron radiation-based phase contrast enhanced micro-computed tomography (SR-PhC-μCT) for imaging of human meniscus. Quantitative parameters related to fiber orientation and crimping were evaluated as potential markers of tissue degeneration.DESIGN: Human meniscus specimens from 10 deceased donors were prepared using different preparation schemes:

Background: - An estimated 240,000 newborns die worldwide within 28 days of birth every year due to congenital birth defect. Exposure to poor indoor environment contributes to poor health outcomes. In this research, we aim to evaluate the association between the usage of different type household cooking fuel and congenital birth defects in Nepal, as well as investigate whether air ventilation usag

This Special Topic focuses on magnetohydrodynamic (MHD) processes in the deep interiors of planets, in which their fluid dynamos are in operation. The dynamo-generated, global, magnetic fields provide a background for our solar-terrestrial environment. Probing the processes within the dynamos is a significant theoretical and computational challenge and any window into interior dynamics greatly inc

Eocene flint 48–56.0 million years old (mya) from the Negev desert (Israel) was characterized using a suite of analytical techniques. High-resolution transmission electron microscopy (HR-TEM) and selected area electron diffraction (SAED) of the inorganic component showed the texture, morphology, size, and distribution of two silica polymorphs: α–quartz and moganite. While euhedral forms were attri

PURPOSE: Many municipalities today, together with other stakeholders, offer group exercises for the older population via municipal meeting places, focusing on promoting good health. During the Covid-19 pandemic, these group exercises either continued in a modified form or ceased. The aim of this study was to explore involved stakeholders' experiences of group exercises for older persons arranged v

Landfills have played a significant role in the recovery of white storks (Ciconia ciconia) populations across various European countries. While there is ample information about the populational-level effects, there is a lack of knowledge regarding the individual effects of using this food resource for feeding nestlings. This study aims to assess the nutritional status and oxidative stress balance

Background: Children with long-gap esophageal atresia (LGEA) risk living with aerodigestive morbidity and mental health difficulties. No previous study has investigated their experiences of schooling, despite the importance of schools in children’s development, learning and social relationships. We aimed to describe experiences of schooling in children with LGEA in Sweden in comparison with childr

The quantum mechanical equivalent of the classical Hall effect can lead to interesting results in solid state physics.A similar effect, that has received attention in recent years, occurs when large spin-orbit coupling is present in a material, the so-called quantum-spin Hall effect.In two-dimensional materials it leads to so-called helical edge states that exhibit counter-propagating electron sta

Vaccinated convalescents do not develop severe COVID-19 after infection with new SARS-CoV-2 variants. We questioned how mRNA vaccination of convalescents provides protection from emerging virus variant. From the cohort of 71 convalescent plasma donors, we identified a patient who developed immune response to infection with SARS-CoV-2 variant of 20A clade and who subsequently received mRNA vaccine

Previously, it has been indicated that oat polar lipids included in a liquid meal may have the potential to beneficially modulate various cardiometabolic variables. The purpose of this study was to evaluate the effects of oat polar lipids in a solid food matrix on acute and second meal glucose tolerance, blood lipids, and concentrations of gut-derived hormones. The oat polar lipids were consumed a

The focus of much sensory language research has been on vocabulary and codability, not how language is used in communication of sensory perceptions. We make a case for discourse-oriented research about sensory language as an alternative to the prevailing vocabulary orientation. To consider the language of sound in authentic textual data, we presented participants with 20 everyday sounds of unknown

INTRODUCTION: Psychiatric disorders are common during pregnancy, affecting up to 16% of pregnant women. Severe depression and anxiety have significant negative effects on the health of both the mother and the developing fetus. Electroconvulsive therapy (ECT) is considered a treatment option for pregnant women with severe psychiatric disorders when other treatments have been ineffective or pose ris

Abdominal aortic aneurysm (AAA) is a mostly silent vascular disease, with a rupture-related mortality rate exceeding 80%. To aid in future diagnosis and prognosis efforts, the studies included in the present thesis have explored the role of specific oxidative stress-related factors in the context of AAA using two population-based cohorts: AAA screening cohort of 65-year-old males (n = 421) and the

A key element for diagnosing cardiac enlargement in an autopsy setting is relevant heart weight references. However, most available references are to a large extent not representative of a medicolegal autopsy population, implying that reference weights are likely lower than those in the relevant population.To establish more applicable heart weight references in a medicolegal autopsy population, we
