Stem cell therapy using human skin-derived neural precursors holds much promise for the treatment of stroke patients. Two main mechanisms have been proposed to give rise to the improved recovery in animal models of stroke after transplantation of these cells. First, the so called by-stander effect, which could modulate the environment during early phases after brain tissue damage, resulting in mod
Objectives: Endovascular repair (ER) of popliteal artery aneurysm (PAA) is an alternative to open repair. However, there is no standardized protocol for when to opt for ER and the decision is therefore at the discretion of the clinician. This study aims to evaluate the adherence to the Instruction For Use (IFU) in patients undergoing ER for PAA and factors associated with stent graft patency at on
Light/dark cycles play an essential role in people's performance, mood and daily rhythm. This study aimed to evaluate an early prototype of a personalised home lighting system including body-worn loggers. A convenience sample (N = 28) wore the devices for 23 h in the field and were given a demonstration of the lighting system components. Participants reported on questionnaires their acceptance of
Background: Little is known about the value of biomarkers for prognostication in hip fracture patients. The main objective of the present study was to assess if biomarkers add useful information to an existing risk score for prediction of 30-day mortality in patients suffering from out of hospital hip fractures. Methods: In a prospective observational single centre study, association between plasm
CuInSe2 (CISe) colloidal quantum dots (QDs) display promising applications in photodetection especially within near-infrared (NIR) regions due to their high extinction coefficient and environmental-friendly. However, the high trap density and poor crystal quality introduced by the ternary structure result in low photodetection of CISe QDs devices. Herein, we dope transition metal manganese ions (M
På särskilda ungdomshem tvångsvårdas barn och unga i Statens institutionsstyrelses (SiS) regi. Personalen på ungdomshemmen har särskilda befogenheter vilket motiveras av de placerade barnen och ungas omfattande problematik. Tvångsåtgärderna inskränker emellertid barn och ungas fri- och rättigheter. Barnkonventionen inkorporerades i svensk lag i syfte att stärka och tydliggöra barn och ungas ställThe special residential homes for young people that are run by the national board of institutional care (SiS) provide children and young people compulsory care. The staff at the special residential homes have the right to use coercive measures which is motivated by the children and young people’s extensive problems. The coercive measures however restrict the freedoms and rights of the children and
Titel: Validering av en handledsburen aktivitetsmätare och en självskattningskala för beräkning av VO2max. Bakgrund: Fysisk aktivitet och god aerob kapacitet är kopplat till god hälsa och lägre risk för livsstilsrelaterade sjukdomar. I dagsläget anses maximalt arbetsprov med ergospirometri och gasanalys för bestämning av VO2max (VO2max-test) vara det mest exakta sättet att mäta aerob kapacitet. Su
As the population increases, so does the need for residential buildings, offices, schools and preschools. The construction industry accounts for about 20% of Sweden’s greenhouse gas emissions. While buildings become more energy-efficient the focus is shifted from the operational phase to the construction phase. The law on climate declaration is a Swedish law, which holds developers responsible for
Syftet med vår uppsats är att utifrån svenska mindre aktiebolags, revisorers och expertorgans perspektiv redogöra för om förslagen i propositionen ”Förenklade redovisningsregler m.m.” och BFNs ”Allmänna råd för K2 - mindre aktiebolag” överensstämmer med vad de anser behöver förenklas. Syftet är också att redogöra för vilken funktion redovisningen har för de mindre aktiebolagen och vilka konsekvens
Objectives: Limited understanding exists regarding non-detected cancers in digital breast tomosynthesis (DBT) screening. This study aims to classify non-detected cancers into true or false negatives, compare them with true positives, and analyze reasons for non-detection. Materials and methods: Conducted between 2010 and 2015, the prospective single-center Malmö Breast Tomosynthesis Screening Tria
We present a novel acoustofluidic chromatography platform for high-throughput nanoparticle trapping and enrichment, with a focus on extracellular vesicles (EVs) from blood plasma. The system features a packed bed of polystyrene beads inside a rectangular glass capillary, acoustically actuated by a piezoelectric element. Using fluorescent polystyrene nanoparticles as small as 25 nm, we characterize
During the COVID-19 pandemic, the Swedish Covid Association (SCA) was established to represent individuals with Long COVID (LC). The unique Swedish response to the pandemic, characterized by minimal restrictions, serves as the backdrop for the SCA’s efforts to highlight the specific needs of LC patients, who were largely excluded from pandemic policies and protective measures. Utilizing the Narrat
Background: Childhood (< 20 years) nervous system tumors manifest in some rare cancer syndromes but how commonly they present with familial clustering between various histological types is not well known at a nation-wide level. Our aim is to enhance understanding of familial risks in childhood nervous system cancers. Methods: We used the Swedish population and cancer data from years 1958–2021 to a
ObjectivesFrequent blood sampling in vulnerable patient groups, such as prematurely born infants, can lead to significant blood loss and increased transfusion needs. Current pre-analytical technology requires comparably large blood volumes and leads to discarding of cells. This study investigates a device prototype enabling in-line sampling where cell-reduced plasma for clinical chemistry analyses
The X-ray flux from X-ray free-electron lasers and storage rings enables new spatiotemporal opportunities for studying in-situ and operando dynamics, even with single pulses. X-ray multi-projection imaging is a technique that provides volumetric information using single pulses while avoiding the centrifugal forces induced by conventional time-resolved 3D methods like time-resolved tomography, and
