The endogenous chemokines CCL19 and CCL21 signal via their common receptor CCR7. CCL21 is the main lymph node homing chemokine, but a weak chemo-attractant compared to CCL19. Here we show that the 41-amino acid positively charged peptide, released through C-terminal cleavage of CCL21, C21TP, boosts the immune cell recruiting activity of CCL21 by up to 25-fold and the signaling activity via CCR7 by

The focus on recovery within psychiatric care is increasing, where peer support may play a pivotal role. Previous research shows both mixed and promising results in terms of beneficial outcomes for patients and peer support workers (PSW). The study’s aim was to investigate PSW’ experiences of their professional role and associated relationships with healthcare staff and patients. Semi-structured i

SyfteMålsättningen med denna studie var dels att säkerställa att tågpersonalen inte utsätts för höga halter av partiklar i sitt arbete på X60B fordon som trafikerar Arlanda. Syftet var även att ta fram ett förhållande mellan partikelnivåerna i tunnelmiljö och ombord på pendeltågsfordon av typ X60B i förarhytterna för att avgöra ventilationsfiltrets kapacitet. Kunskapen om filtreringseffektiviteten

Excessive tissue deformation near cartilage lesions and acute inflammation within the knee joint after anterior cruciate ligament (ACL) rupture and reconstruction surgery accelerate the loss of fixed charge density (FCD) and subsequent cartilage tissue degeneration. Here, we show how biomechanical and biochemical degradation pathways can predict FCD loss using a patient-specific finite element mod

Advanced therapies for Parkinson's disease (PD) constitute a broad range of treatments, each presenting specific ethical challenges. Some of these therapies are established and in clinical use, like device-aided therapies, and others, based on advanced therapeutic medicinal products (ATMPs), are still in early stage of clinical trials. This paper focuses on some common ethical issues arising in th

Splicing and translation are two of the key steps of post-transcriptional regulation of gene expression. Their tight regulation is essential for development, whereas their deregulation is involved in cancer pathogenesis. Nevertheless, many of the molecular mechanisms controlling these processes are still unknown. Hence, the main aim of this thesis is to elucidate novel regulatory mechanisms that a

Objectives: To compare physical impairments between patients with hip-related pain and those with non-hip-related groin pain, and to compare both patient groups with healthy controls. Design: Cross-sectional. Participants: Eighty-one hip and groin pain patients were consecutively included and categorized into having hip-related pain or non-hip-related groin pain. Twenty-eight healthy controls were

Background: In many high-income countries, life expectancy (LE) has increased, with women outliving men. This gender gap in LE (GGLE) has been explained with biological factors, healthy behaviours, health status, and sociodemographic characteristics, but little attention has been paid to the role of public health policies that include/affect these factors. This study aimed to assess the contributi

We studied the gas-phase photodissociation of a fully halogenated aromatic molecule, tetrabromothiophene, upon core-shell ionization by using synchrotron radiation and energy-resolved multiparticle coincidence spectroscopy. Photodynamics was initiated by the selective soft X-ray ionization of three elements-C, S, and Br-leading to the formation of dicationic states by Auger decay. From a detailed

This paper reviews the current literature regarding iron oxide formation in the wheel-rail contact in order to assess the possible role of iron oxides in the “Wet-Rail” phenomenon, which causes low adhesion between the wheel and the rail. The paper discusses the structure and formation of oxides from a chemical perspective before analysing the direct tribological effects and outlining the techniqu

The amino acid sequence of the cysteine-containing regions of human complex-forming glycoprotein, heterogeneous in charge (protein HC) was determined by studies of the tryptic peptides of the completely reduced and radioalkylated protein. One of the cysteines was located in the amino-terminal part of the molecule at position 34....Diagonal map electrophoresis showed that the cysteine residue in th
