Treatment with cyclosporin A during sensitization with trimellitic anhydride attenuates the airway responses to allergen challenge three weeks later

The present studies examined the effects of oral treatment with cyclosporin A, betamethasone or azelastine administered over the time of sensitization with trimellitic anhydride on allergen-induced airway responses, compared to those of control animals given corn oil alone. Drugs were given for 8 days. The animals were sensitized with trimellitic anhydride (0.1 ml of 0.3% w/v) in corn oil given in

Green roofs on municipal buildings in Lund : modeling potential environmental benefits

Gröna tak kan minska problem med s.k. urban heat islands och kan användas för dagvattenhantering. Andra miljöfördelar som en förbättring av luftkvalitet, biodiversitet och bullerminskning finns också. Detta projekt fokuserar på lokala (kommunala) medel för att skapa en bättre miljö med extensiva gröna tak, vilka är nästan underhållsfria. Ett delområde i Lund som inkluderar Universitetet och UniverGreen roofs have the potential to mitigate problems with an urban heat island and to act as an element in stormwater management. Other environmental benefits exist as well, such as improvement of air quality, biological diversity and noise reduction. This project focuses on local community efforts to create a better environment through the use of extensive green roofs, which require almost no main

TGF-beta enhances the production of hyaluronan in human lung but not in skin fibroblasts

Transforming growth factor-beta (TGF-beta) enhances the production of extracellular matrix components, such as type I and type III collagen, fibronectin, proteoglycans, in various cell types. The effect on hyaluronan synthesis in relation to proteoglycan synthesis has not been investigated. Human lung or skin fibroblast cultures were treated with TGF-beta in serum-free medium for various periods o

Intestinal Ischemia and Reperfusion Injury - Pathophysiology as basis for novel treatment

Popular Abstract in Swedish Mesenteriell ischemi (nedsatt blodcirkulation till tarm och övriga bukorgan) är vanligt förekommande vid ett flertal olika sjukdomstillstånd som t ex blödnings-, septisk och cirkulatorisk chock. Inte minst är tarmen mycket känslig för nedsättning av blodflödet. Tarmskadan, inkluderande dess barriär(skydds-)funktion sker dels under perioden med nedsatt blodförsörjning meIntestinal ischemia and reperfusion (I/R) is not infrequent in the clinical situation and the intestinal barrier plays an important role in gut barrier function, preventing not at least septic complications and potentially the development of the multiple organ dysfunction syndrome. Mechanisms of intestinal I/R induced gut epithelial and endothelial barrier dysfunction and remote organ dysfunction

Release of neutrophil proteinase 4(3) and leukocyte elastase during phagocytosis and their interaction with proteinase inhibitors

Neutrophil proteinase 4 (NP4) is a major neutral proteinase of the human polymorphonuclear (PMN) leukocyte, which is present in amounts similar to leukocyte elastase. NP4(3) is a potent, non-specific proteinase, which may degrade structural and soluble proteins in the tissues and body fluids, and it has been implicated as an important pathogenetic factor in lung emphysema. We have studied the rele

The prognostic value of FET PET at radiotherapy planning in newly diagnosed glioblastoma

Background: Glioblastoma patients show a great variability in progression free survival (PFS) and overall survival (OS). To gain additional pretherapeutic information, we explored the potential of O-(2-18F-fluoroethyl)-L-tyrosine (FET) PET as an independent prognostic biomarker. Methods: We retrospectively analyzed 146 consecutively treated, newly diagnosed glioblastoma patients. All patients were

The impact of the glucagon-like peptide 1 receptor agonist liraglutide on the streptozotocin-induced diabetic mouse kidney proteome

In diabetes mellitus (DM), the kidneys are exposed to increased levels of hyperglycemia-induced oxidative stress. Elevated amounts of reactive oxygen species (ROS) are believed to provoke ultrastructural changes in kidney tissue and can eventually result in DM late complications such as diabetic nephropathy. While it is reported that glucagon-like peptide 1 receptors (GLP-1R) are present in the ki

Normal tissue sparing potential of scanned proton beams with and without respiratory gating for the treatment of internal mammary nodes in breast cancer radiotherapy

Proton therapy has shown potential for reducing doses to normal tissues in breast cancer radiotherapy. However data on the impact of protons when including internal mammary nodes (IMN) in the target for breast radiotherapy is comparatively scarce. This study aimed to evaluate normal tissue doses when including the IMN in regional RT with scanned proton beams, with and without respiratory gating. T

Bacterial outer membrane vesicles induce vitronectin release into the bronchoalveolar space conferring protection from complement-mediated killing

Pathogens causing pneumonia utilize the complement regulator vitronectin to evade complement-mediated killing. Although vitronectin is associated with several chronic lung diseases, the role of bronchoalveolar vitronectin in pneumonia has not been studied. This study sought to reveal the involvement of vitronectin in the bronchoalveolar space during pneumonia, to assess the effect of outer membran

Poloxamer/sodium cholate co-formulation for micellar encapsulation of doxorubicin with high efficiency for intracellular delivery : An in-vitro bioavailability study

Hypothesis: Doxorubicin hydrochloride (DX) is widely used as a chemotherapeutic agent, though its severe side-effects limit its clinical use. A way to overcome these limitations is to increase DX latency through encapsulation in suitable carriers. However, DX has a high solubility in water, hindering encapsulation. The formulation of DX with sodium cholate (NaC) will reduce aqueous solubility thro

Mortality and morbidity of low-grade red blood cell transfusions in septic patients : a propensity score-matched observational study of a liberal transfusion strategy

Background: Red blood cell (RBC) transfusions are associated with risks including immunological reactions and volume overload. Current guidelines suggest a restrictive transfusion strategy in most patients with sepsis but based on previous randomized controlled trials and observational studies, there are still uncertainties about the safety in giving low-grade RBC transfusions to patients with sep

Protein kinase A-dependent and -independent stimulation of exocytosis by cAMP in mouse pancreatic B-cells

1. The mechanisms by which cAMP stimulates Ca(2+)-dependent insulin secretion were investigated by combining measurements of whole-cell Ca2+ currents, the cytoplasmic free Ca2+ concentration ([Ca2+]i) and membrane capacitance in single mouse B-cells maintained in tissue culture. 2. Cyclic AMP stimulated exocytosis > 4-fold in whole-cell experiments in which secretion was evoked by intracellular di

A New Easy-to-Prepare Homogeneous Continuous Electrochromatographic Bed for Enantiomer Recognition

Completely homogeneous polyacrylamide-based gels were used for capillary electrochromatography (CEC) of drug enantiomers. Like continuous beds (also called continuous polymer rods, silica rods, monoliths) they do not require frits to support the bed, because it is covalently linked to the capillary wall. Along lifetime is an important feature of the beds. The gel matrices can be prepared in any la

Access to Cross-Border Healthcare for Older Persons in the European Union : The Interplay between EU Law and Swedish Law

This thesis deals with older persons on the move and their access to cross-border healthcare in the European Union. The number of persons crossing borders within the EU has increased exponentially in recent decades. Free movement has been at the core of the European integration project from its early days. Although it was originally intended to apply only to those who were economically active, the

Fluctuating potentials in GaAs : Si nanowires: Critical reduction of the influence of polytypism on the electronic structure

In this work, the effects of Si doping in GaAs nanowires (NWs) grown on GaAs (111)B by molecular beam epitaxy with different Si doping levels (nominal free carrier concentrations of 1 × 1016, 8 × 1016, 1 × 1018 and 5 × 1018 cm-3) are deeply investigated using scanning electron microscopy (SEM), transmission electron microscopy (TEM), grazing incidence X-ray diffraction (GID), photoluminescence (PL

Comparison of MAPIE versus MAP in patients with a poor response to preoperative chemotherapy for newly diagnosed high-grade osteosarcoma (EURAMOS-1) : an open-label, international, randomised controlled trial

Background We designed the EURAMOS-1 trial to investigate whether intensified postoperative chemotherapy for patients whose tumour showed a poor response to preoperative chemotherapy (≥10% viable tumour) improved event-free survival in patients with high-grade osteosarcoma. Methods EURAMOS-1 was an open-label, international, phase 3 randomised, controlled trial. Consenting patients with newly diag

Suppression of gastric acid secretion in patients with gastroesophageal reflux disease results in gastric bacterial overgrowth and deconjugation of bile acids

The aim of this study was to test the hypothesis that gastric bacterial overgrowth is a side effect of acid suppression therapy in patients with gastroesophageal reflux disease (GERD) and that the bacteria-contaminated gastric milieu is responsible for an increased amount of deconjugated bile acids. Thirty patients with GERD who were treated with 40 mg of omeprazole for at least 3 months and 10 pa

Influence of Severe Hypoglycemia on Brain Extracellular Calcium and Potassium Activities, Energy, and Phospholipid Metabolism

Abstract: In the cerebral cortices of rats, during insulininduced hypoglycemia, changes in the concentrations of labile phosphate compounds [ATP, ADP, AMP, and phosphocreatine (PCr)] and glycolytic metabolites (lactate, pyruvate, and glucose) as well as phospholipids and free fatty acids (FFAs) were studied in relation to extracellular potassium and calcium activities. Changes in extracellular cal

Impact of bacterial ice nucleating particles on weather predicted by a numerical weather prediction model

Bacterial ice-nucleating particles (INP) have the ability to facilitate ice nucleation from super-cooled cloud droplets at temperatures just below the melting point. Bacterial INP have been detected in cloud water, precipitation, and dry air, hence they may have an impact on weather and climate. In modeling studies, the potential impact of bacteria on ice nucleation and precipitation formation on
