En kartläggning och jämförelse av sambandet mellan fysisk aktivitet och sömn i olika populationer - en kvantitativ enkätstudie

Bakgrund: Studier har visat att regelbunden fysisk aktivitet har god effekt på sömnen. Det finns även forskning som tyder på att detta samband kan skilja sig beroende på kön och ålder. Det saknas dock studier som jämför sambandet i grupper med olika sysselsättningar. Vidare saknas det studier i en svensk kontext som undersöker sambandet, hur det skiljer sig mellan; män och kvinnor, olika åldersgru

The evolution of support networks among unmarried childless older men in rural China

Unmarried childless older men in rural China represent a growing group who face distinct care situations. Support networks are essential to their health and care, yet those networks remain understudied. This study aims to investigate the support networks available to this group, how they change over time, and the factors affecting their development. Guided by a situational perspective on care, the

Objective: To investigate the expression of Pyruvate dehydrogenase kinase 1(PDK1), phosphorylated Pyruvate dehydrogenase (p-PDH) and Pyruvate kinase isozyme type M2 (PKM2) based on Warburg effect pathway in cervical cancer tissues, and explore the roles of these molecules on prognosis and recurrence after postoperative radiation. Methods: The expressions of PDK1, p-PDH and PKM2 in primary tissues

Timing and combinations of cardiovascular diseases in survivors of childhood, adolescent, and young adulthood cancer

BACKGROUND: Children, adolescents, and young adults with cancer (referred to as CAYAs) are at risk of long-term health complications, with cardiovascular disease (CVD) being a major concern. In addition, sociodemographic characteristics and traditional cardiovascular risk factors may also contribute to disparities in outcomes compared with those of the general population. The aim of this study was

Diagnostic aspects of abdominal aortic aneurysm disease in men with reference to population-based screening. : Possibilities for refinement of ultrasound screening for abdominal aortic aneurysm in 65-year-old men.

Introduction Abdominal aortic aneurysm (AAA) mainly affects elderly men, grows slowly, and carries high mortality if left untreated, as rupture risk increases with larger diameters. AAA is well suited for screening due to its slow progression, long latent phase, reliable diagnostics, and established treatments. The primary aim of this thesis was to assess whether absolute infrarenal aortic diamete

Towards a Global Plastics Treaty: Navigating Policy Preferences and Economic Interests

At the fifth session of the United Nations (UN) Environment Assembly in March 2022, UN member states were mandated to negotiate an international, legally binding instrument on plastic pollution. This article assesses pre-session submissions from the second and third negotiation rounds to identify proposed measures and priorities for the treaty. The analysis, employing systematic qualitative conten

Visuo-Locomotive Update in the Wild The Role of (Un)Familiarity in Choice of Navigation Strategy, and its Application in Computational Spatial Design

We study active human visuo-locomotive experience in everyday navigation from the viewpoints of environmental familiarity, embodied reorientation, and (sensorimotor) spatial update. Following a naturalistic, in situ, embodied multimodal behaviour analysis method, we conclude that familiar users rely on environmental cues as a navigation-aid and exhibit proactive decision-making, whereas unfamiliar

How to turn over an egg: Rethinking the temporality of global value chains amidst emerging infectious diseases

The temporality of global value chains is an important area of concern for economic geographers. This paper argues for the analytical value of closely examining the category of ‘turnover time’ as articulated in Marx’s work and subsequent historical-geographical materialism. We argue that turnover times of capitals in competition – hence struggles over time – can be conceptualised as a driving forc

The Use of AI in Educational Environments and the Children's Right to Freedom of Thought and Conscience

De aktuella frågeställningarna i denna uppsats är: Hur försäkrar artikel 5(1)(a) AI förordningen uppfyllandet av baThis thesis investigates the use of AI within the educational environment, specifically the school environment, and the potential challenges and barriers for article 5(1)(a) AI Act, to ensure the realization of the children’s right to freedom of thought and conscience, under article 14 UNCRC. The research questions are: How does article 5(1)(a) AI Act ensure the realization of the children’s righ

Trafiksäkerhet i en större cirkulationsplats för oskyddade trafikanter

Sammanfattning Denna studie undersöker hur olika åtgärder kan påverka trafiksäkerheten för oskyddade trafikanter vid cirkulationsplatser. Studien bygger på en analys av trafiksituationen på en cirkulationsplats i Helsingborg. Bedömningen av trafiksituationen genomfördes med hjälp av tre metoder: hastighetsmätningar med radarpistol, en konfliktanalys mellan olika trafikgrupper baserat på filmat maSummary This study examines how various measures can impact traffic safety for vulnerable road users at roundabouts. The study is based on an analysis of traffic conditions at a roundabout in Helsingborg. The assessment was conducted using three methods: speed measurements with a radar gun, a conflict analysis between different traffic groups based on recorded footage, and a summary analysis of S

A scholarly quest for meaning : Negotiating scholar-activism at the intersection of structure and agency

Universities, operating at the intersection of state, market, and civil society, are increasingly called upon to address urgent global challenges, such as climate change, inequalities, and social injustice. This has given rise to hybrid roles for scholars, ranging from public intellectuals to policy advisers and academic entrepreneurs. Among these roles, scholar-activism stands out by explicitly a

Modeling Mitral Valve Dynamics: From Experimental Validation to Patient-Specific Simulations

Hjärtat består av fyra hålrum; två kammare och två förmak, som separeras av fyra hjärtklaffar. Dessa säkerställer att blodet enbart flödar åt ett håll och ger därmed hjärtat förutsättningarna för effektiv pumpning av blodet. Mitralisklaffen är en av dessa fyra hjärtklaffar och separerar vänster förmak från vänster kammare, vilket gör att den utsätts för det högsta trycket i hjärtat. För att mitralThe heart consists of four chambers, two atria and two ventricles, separated by four valves that ensure unidirectional blood flow and efficient cardiac function. Among these, the mitral valve regulates blood flow between the left atrium and left ventricle and is one of the most mechanically loaded structures in the heart, stabilized by the chordae tendineae, which are connective structures. Conseq

Isolation of high yield and quality RNA from human precision-cut lung slices for RNA-sequencing and computational integration with larger patient cohorts

Precision-cut lung slices (PCLS) have gained increasing interest as a model to study lung biology and disease, as well as for screening novel therapeutics. In particular, PCLS derived from human tissue can better recapitulate some aspects of lung biology and disease as compared to PCLS derived from animals (e.g. clinical heterogeneity), but access to human tissue is limited. A number of different

Accurate genotype-based demultiplexing of single cell RNA sequencing samples from non-human animals

Single cell sequencing technologies (scRNA-seq, scATAC-seq, etc.) have revolutionized the study of complex tissues and unique organisms, providing researchers with a much needed species agnostic tool to study biological processes at the cellular level. To date, scRNA-seq technologies are expensive, require sufficient cell quantities, and need biological replicates to avoid batch effects or artifac

Institutional Innovation and the Adoption of New Technologies : The Case of Steam

This paper documents how the advent of the limited liability corporation contributed to the diffusion of steam technology during Sweden's industrialization. Using longitudinal establishment-level data, we show that incorporation sharply raised the probability that industrial establishments adopted steam. Incorporation facilitated technology adoption partly by enabling smaller establishments to exp

The genomic landscape of relapsed infant and childhood KMT2A-rearranged acute leukemia

To study the mechanisms of relapse in KMT2A-rearranged (KMT2A-r) acute lymphoblastic (ALL) and acute myeloid leukemia (AML), we performed whole-genome and exome sequencing of infants and children with relapsed ALL/AML (n = 36), and longitudinal deep-sequencing of 257 samples in 30 patients. Somatic alterations in drug-response genes, most commonly in TP53 and IKZF1 (64%), were highly enriched in e
