The complement system is activated in response to tissue injury. During wound healing, complement activation seems beneficial in acute wounds but may be detrimental in chronic wounds. We found that the epidermal expression of many complement components was only increased to a minor extent in skin wounds in vivo and in cultured keratinocytes after exposure to supernatant from stimulated mononuclear

It is well established that adaptive immune responses induced by hypercholesterolemia play an important role in the development of atherosclerosis, but the pathways involved remain to be fully characterized. In the present study we assessed immune responses to hypercholesterolemia induced by feeding Apoe-/- mice a high-fat diet for 4 or 8 weeks.

SUMMARY AT A GLANCE: Secretory leukocyte proteinase inhibitor (SLPI) is a major anti-elastase barrier at the epithelial surfaces of upper respiratory tract. Our findings indicate clear up-regulation of SLPI in response to endotoxin in nasal secretions. In addition, SLPI shows dose-dependent anti-apoptotic and chemotactic effects on primary human neutrophils. ABSTRACT: Background and objective: The

Small intestinal lamina propria (SI-LP) CD103(+) dendritic cells (DCs) are imprinted with an ability to metabolize vitamin A (retinol), a property underlying their enhanced capacity to induce the gut-homing receptors CC chemokine receptor-9 and α4β7 on responding T cells. In this study, we demonstrate that imprinting of CD103(+) DCs is itself critically dependent on vitamin A and occurs locally wi

A supramolecular complex composed of Ru(II) tris-bipyridine, tyrosine, and dipicolylamine was synthesized and characterized. This complex was attached to TiO2 nanocrystalline films via ester groups at the Ru(II) chromophore, and photoinduced multistep electron transfer was investigated by laser flash photolysis and electron paramagnetic resonance techniques. Following ultrafast electron injection

ObjectivesAn endovascular aneurysm repair (EVAR) graft is a catheter-implanted vascular prosthesis and is the preferred treatment for patients with aortic aneurysm. If an EVAR graft becomes the focus of infection, the treatment possibilities are limited as it is technically difficult to remove the graft to obtain source control. This study examines whether Pseudomonas aeruginosa and Staphylococcus

Responding to perceived threats is energetically expensive and can require animals to curtail somatic repair, immunity, and even reproduction to balance energy ledgers. In birds and mammals, energetic demands of thermoregulation are often immense, yet whether homeostatic body temperatures are also compromised to aid the stress response is not known. Using data sourced from over 60 years of literat

Atherosclerosis, the underlying pathology of cardiovascular diseases such as myocardial infarction and ischemic stroke, is characterized by chronic inflammation. T cells are present in atherosclerotic plaques and have been implicated in its pathogenesis. This thesis describes studies exploring both the regulation of T cells in atherosclerosis as well as immunomodulatory therapeutics. To study the

BACKGROUND: The study aimed to show the relationship between a large number of circulating metabolites and subsequent cardiovascular disease (CVD) and subclinical markers of CVD in the general population. METHODS AND RESULTS: In 2278 individuals free from CVD in the EpiHealth study (aged 45–75 years, mean age 61 years, 50% women), 790 annotated nonxenobiotic metabolites were measured by mass spect

The preservation of labile biomolecules presents a major challenge in chemistry, and deep eutectic solvents (DESs) have emerged as suitable environments for this purpose. However, how the hydration of DESs impacts the behavior of proteins is often neglected. Here, we demonstrate that the amino acid environment and secondary structure of two proteins (bovine serum albumin and lysozyme) and an antib

ABSTRACT:Introduction / Rationale: From the onset of the COVID-19 pandemic, social distancing was recommended for adults 70 years and older (70+) in Sweden. From an outside view, they then became deprived of possibilities to engage in meaningful activities. However, as meaning is highly subjective, we need to listen to older adults’ voices to really know.Objectives: To explore how adults 70+ exper

In this study, we discuss Swedish travelers from different backgrounds during their visits to Greece and Asia Minor in the 18th century. Besides their scientific interests, they write about their impressions of the Greeks and other people in the area, as well as education, language, religion, local economy, culture, and social life. They have good knowledge of ancient Greek history and the Greek l

Bioarchaeological evidence of interpersonal violence and early warfare presents important insights into conflict in past societies. This evidence is critical for understanding the motivations for violence and its effects on opposing and competing individuals and groups across time and space. Selecting the Neolithic of northwestern Europe as an area for study, the present paper examines the variati

BACKGROUND: The EAT-Lancet Commission proposed a globally environmentally sustainable dietary pattern featuring mainly plant-based foods in 2019. However, evidence on this dietary pattern in preventing coronary events is minimal.OBJECTIVE: We aimed to examine the association between the EAT-Lancet diet and risk of coronary events.METHODS: The Malmö Diet and Cancer cohort study (recruited between 1

Aqueous dispersions of charged-neutral block copolymers (poly(acrylamide)-b-poly(acrylate)) complexed with an oppositely charged surfactant (dodecyltrimethylammonium) have been prepared by different approaches: the simple mixing of two solutions (MS approach) containing the block copolymer and surfactant, with their respective simple counterions, and dispersion of a freeze-dried complex salt prepa

Euro50 is a proposed optical telescope with an equivalent primary mirrordiameter of 50 m. Partners of the collaboration are institutes inSweden, Spain, Ireland, Finland, and the UK. The telescope will have asegmented primary mirror and an aplanatic Gregorian configuration withtwo elliptical mirrors. For a 50 m telescope there would be noeconomical advantage in going to a spherical primary. The siz

Popular Abstract in Swedish Antalet människor som insjuknar i cancer (cancerincidensen) runtom i världen ökar, exempelvis i Sverige har antalet diagnosticerade tumörer ökat med i snitt 2.1% per år de senaste 20 åren. Denna ökning förklaras bland annat av vår ökade livslängd och vårt val av livsstil. Trots detta har antalet människor som dör i cancer minskat de senaste 20 åren. Dessa motsägelsefullThe continual increase in incidence of cancer has created an urgent need for improved methods for diagnosis, prognosis and/or treatment. In this context, the field of biomarker research has expanded immensely during the last few years. This thesis, based on four original papers, revolves around protein biomarker discovery in cancer. For this purpose, an in-house design recombinant antibody microar
