Populärvetenskaplig sammanfattning: En mycket reaktiv spårgas i Amazonas. Växter släpper ut flyktiga organiska ämnen, som är mycket viktiga eftersom de släpps ut i stora mängder och påverkar tillverkningen av aerosoler, förändrar luftkvaliteten och fungerar som kommunikation mellan växter och herbivorer. Det här arbetet presenterar uppmätningar av sesquiterpener, vilka är flyktiga organiska partikSesquiterpenes are highly reactive terpenoids produced by vegetation and may serve many important biological functions such as acting as antioxidants and as semiochemicals (chemicals acting as messengers within or between species). Once emitted to the atmosphere, by reacting with oxidants like ozone and contributing to secondary organic aerosol formation, the emission of sesquiterpenes from vegeta

En ofta använd behandlingsmetod mot cancer är strålbehandling. Inför en sådan behandling undersöks patienten ofta med en typ av röntgenundersökning som kallas datortomografi (eng. computed tomomgraphy, CT). Röntgenbilderna visar hur mycket av strålningen som absorberas av kroppen, vilket innebär att man tydligt ser skillnad mellan ben, som absorberar mer av strålningen än vävnad och luft, som strå"Introduction; The aim of this study was to examine the possibilities for MRI-based radiotherapy treatment planning. The work included evaluation of geometric image distortions in MR-images, investigations of how segmentation of bone could be performed from images acquired with the ultra short time of echo (UTE) pulse sequence and assessment of dosimetric differences between treatment plannin

This study examined whether Growth Differentiation Factor-15 (GDF-15) and echocardiographic measures of systolic left ventricular function improve intermediate- and long-term mortality risk prediction beyond the guideline-endorsed GRACE 2.0 score after Acute Coronary Syndrome (ACS). 751 ACS patients were included. GDF-15, left ventricular ejection fraction (LVEF), and global longitudinal strain (G

Background: Five risk factors account for approximately 50% of the global burden of cardiovascular disease. How the presence or absence of classic risk factors affects lifetime estimates of cardiovascular disease and death from any cause remains unclear. Methods: We harmonized individual-level data from 2,078,948 participants across 133 cohorts, 39 countries, and 6 continents. Lifetime risk of car

Background: Dementia is a growing public health concern, and although diet is a modifiable potential risk factor, the role of free sugar intake remains unclear. Excess sugar has been linked to metabolic and cardiovascular dysfunction, both associated with cognitive decline, but evidence regarding specific sugar sources is limited. Objectives: This study aimed to investigate the associations betwee

Blood biomarkers have the potential to revolutionize Alzheimer's disease diagnosis, offering advantages over CSF and PET due to their accessibility, scalability and cost-effectiveness. This study evaluated the effectiveness of individual plasma biomarkers, such as phosphorylated Tau (pTau) 217, as well as biomarker combinations, with a focus on the pTau 217/β-Amyloid (Aβ) 1–42 ratio to predict amy

AbstractBackground and purpose: The need for knee replacement revision arises from a combination of patient, prosthesis and surgeon factors. Registry data can help study these relationships. Pooling data from multiple registries may increase both reliability and generalizability. The study aim was to gain a multi-national overview of knee replacement revision, to inform best-practice and improve o

GTP-cyclohydrolase deficiency in dopa-responsive dystonia (DRD) patients impairs the biosynthesis of dopamine, but also of serotonin. The high prevalence of non-motor symptoms suggests involvement of the serotonergic pathway. Our study aimed to investigate the serotonergic system in vivo in the brain of`DRD patients and correlate this to (non-)motor symptoms. Dynamic [11C]DASB PET scans, a marker

Twenty-three lines from a mutagenized Bangladeshi BARI Gom-25 wheat population that included previously identified salt-tolerant lines, and the BARI Gom-25 control variety, were cultivated in a drip-irrigated salinity test field at Salt Farm Texel, Netherlands, to assess their performance during salt stress in European climatic conditions. Lines were tested at irrigation salinity levels of 1, 4, 8

CONTEXT: Minipuberty, a period of a transient activation of the hypothalamic-pituitary-gonadal (HPG) axis in both sexes, enables evaluation of gonadal function in infants suspected of hypogonadism. However, female minipuberty remains poorly elucidated. OBJECTIVE: We aimed to establish continuous reference ranges for the most commonly used reproductive hormones and to evaluate the dynamics of the H

BACKGROUND: Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) has improved the survival in selected colorectal cancer patients with peritoneal metastases. In these patients, the risk of a low anastomosis is sometimes diminished through the creation of a colostomy. Currently, the morbidity and mortality associated with the reversal of the colostomy in this population

Background: Clubfeet are typically shorter than normal feet. This study aimed first to describe the development of foot length in a consecutive series of children with congenital clubfoot and second to relate foot length to development of relapse and motion quality. Methods: Foot length was measured every 6 months in 72 consecutive children with congenital clubfoot (29 bilateral) aged from 2 to 7

Purpose: A pilot study to identify bacterial biofilm in the lacrimal sacs of patients with chronic dacryocystitis, and in patients with epiphora but without discharge, using scanning electron microscopy. Methods: Five patients: two with nasolacrimal duct obstruction without dacryocystitis, and three with dacryocystitis refractory to antibiotics, underwent external dacryocystorhinostomy. One contro

According to guidelines, total ischemic time for homografts at processing must be kept short to avoid degeneration. Many homografts are discarded due to practical inability to finish all steps from procurement to cryopreservation within the time limit. Although, several studies have shown that homografts with prolonged ischemic time show adequate quality and performance. Twenty aortic and 12 pulmo

Achieving high follow-up rates after smoking cessation interventions (SCIs) is a general challenge. The aim of this study was to identify preferences among patients and therapists for improving follow-up rates and to assess smoking status at 6 months among patients lost to follow-up. From the Danish STOPbase for Tobacco and Nicotine, which collects data on SCI across health care, 20 representative

Thylakoid membranes isolated from spinach have previously been shown to inhibit lipase/co-lipase and prolong satiety in vivo. There is a need to develop thylakoid products that not only have the desired characteristics and functionality after processing, but also are stable and provide equivalent effect on appetite over the promised shelf life. The aim of the present study was therefore to evaluat

The NEO model, developed by Lindström (2019) for paperboard, is a non-linear material model that utilizes empirically based constitutive relations with switches to mimic elastic-plastic responses. Due to the explicit definition of the constitutive relations, the NEO model does not require a constitutive equilibrium loop. This, in addition to modeling flexibility from the switches, poses the NEO mo

Agenda 2030 Graduate School monthly newsletter #3 2025-03-10 Ylva van Meeningen Hi! Okay! I do not know about you, but this has so far been a quite different start of the year. It has been unusually dark, people seem to have been more sick (including my family. Just these past two months we have been more sick than we have otherwise been for an entire year!) and all the turmoil in the world that s
