Popular Abstract in Swedish Bakgrund 5-Fluorouracil (5-FU) är ett cytostatikum, även kallat cellgift (ett ämne som hämmar tillväxten av cancerceller), som använts för behandling av cancersjukdom sedan många decennier. Det kan ges både i snabb injektion och i dropp över flera dygn. 5-FU har tyvärr flera vanliga biverkningar. Man kan få påverkan av slemhinnor i magtarm-kanalen, vilket ger sår i munnThe cytostatic drug 5-fluorouracil (5-FU) has been shown to affect both morphology and function of vascular endothelium. These effects could be part of the pathophysiology for 5-FU induced cardiotoxicity. The present thesis explores the mechanisms of this endothelial toxicity. In an animal model, treatment with thromboprophylactic doses of the low-molecular weight heparin (LMWH) dalteparin could

Aims. To investigate the effects of selective beta(2)- and selective beta(3)-adrenoceptor (AR) agonists on prostaglandin (PG) E-2-induced bladder hyperactivity in conscious free-moving rats. Methods. Female Sprague-Dawley rats were anesthetized for implantation of bladder, intravenous, and intra-arterial catheters. The effects of a beta(3)-AR agonist (CL316,243) on cystometric and cardiovascular p

The prostanoid thromboxane (TX)A2 plays a central role in haemostasis and is increasingly implicated in cancer progression. TXA2 signals through two T Prostanoid receptor (TP) isoforms termed TPa and TPβ, with both encoded by the TBXA2R gene. Despite exhibiting several functional and regulatory differences, the role of the individual TP isoforms in neoplastic diseases is largely unknown. This stud

The effect of hydrophilically modified polystyrene, poly(styrene-g-poly(ethylene oxide)), P(S-g-PEC), on the viscosity of ACT oil-continuous microemulsions has been investigated as a function of PS and PEO chain lengths and PEO chain density. A series of polymers, P (S-g-PEO) with PEO chain lengths of 23 or 9, and different graft densities were synthesized by living radical polymerization. Thus, a

We examined herbivore-induced responses of alfalfa (Medicago sativa) and cotton (Gossypium hirsutum) under different CO2 conditions. Plants were grown under ambient (350 ppm) or elevated (700 ppm) CO2 levels, and were either damaged or undamaged by Spodoptera littoralis larvae. At harvest, growth of undamaged (control) plants was determined, and foliar chemical composition of both undamaged and da

Introduction The aim of this study was to describe the complications of ureteroscopy (URS) and to investigate whether performing URS outside normal working hours leads to increased risk for clinically significant complications. Material and methods A cohort of 486 consecutive patients treated with URS, with a total of 567 sessions between 2009 and 2015 at Helsingborg/Ängelholm Hospital, Sweden, wa

Increased intraluminal pressure of the rat portal vein in vivo causes hypertrophy and altered contractility in 1 to 7 days. We have used organ cultures to investigate mechanisms involved in this adaptation to mechanical load. Strips of rat portal vein were cultured for 3 days, either undistended or loaded by a weight. Length-force relations were shifted toward longer length in stretched cultured v

Adsorption of uncharged homopolymers in good and theta solvents onto planar surfaces at various chain flexibility and polymer-surface attraction strengths was investigated by using a coarse-grained bead-spring polymer model and simulation techniques. Equilibrium properties of the interfacial systems were obtained from Monte Carlo simulations by monitoring the bead and polymer density profiles, the

From trash to treasure – detta är återbruk Vi lever idag i ett samhälle där ”slit och släng” är vanligt för bland annat kläder, möbler och leksaker. När något går sönder eller en nyare modell finns ute på marknaden slängs många föremål som hade kunnat användas (återbrukas). Att slänga föremål som fungerar eller hade kunnat lagas, skadar miljön. Det finns en tro om att återbruk av föremål inte är fToday we wear and tear objects and materials, in line with the linear economy. By instead reusing, the need for new production decreases, and so the extraction of raw materials, greenhouse gas emissions and generation of waste. By increasing the reuse rate, we can strive towards a circular economy and climb EUs waste hierarchy. The aim of this master’s dissertation was to study different business

In Sweden the academic year consists of an autumn and a spring semester - 30 ECTS respectively (60 ECTS for the full academic year).The autumn semester last from the start of September to mid-January, but there is no teaching activities during Christmas and the New Year). The spring semester lasts from mid-January to the beginning of June. Semester 1 (autumn)The first semester consists of four cou

Wnt-5a is a non-transforming Wnt protein that is implicated in cell-polarity, adhesion and motility. We have previously shown that low expression of Wnt-5a is a predictor of shorter disease-free survival in human breast cancer. Here, we investigated whether ss-catenin/E-cadherin mediated cell-cell adhesion was affected by loss of Wnt-5a in breast carcinomas, thereby promoting a metastatic behavior

The affinity of AMD3100, a symmetrical nonpeptide antagonist composed of two 1,4,8,11-tetraazacyclotetradecane (cyclam) rings connected through a 1,4-dimethylene(phenylene) linker to the CXCR4 chemokine receptor was increased 7, 36, and 50-fold, respectively, by incorporation of the following: Cu2+, Zn2+, or Ni2+ into the cyclam rings of the compound. The rank order of the transition metal ions co

Background: Increased expression of cyclooxygenase-2 (COX-2) is common in non-small cell lung cancer (NSCLC) and has been associated with poor prognosis. Experimental and clinical phase II trials have indicated that the addition of the COX-2 inhibitor celecoxib to palliative chemotherapy might increase survival time in patients with advanced NSCLC. Methods: We performed a double-blind, placebo-con

The regulation of the structural composition and complexity of the mycelium of arbuscular mycorrhizal (AM) fungi is not well understood due to their obligate biotrophic nature. The aim of this study was to investigate the structure of extraradical mycelium at high and low availability of carbon (C) to the roots and phosphorus (P) to the fungus. We used monoxenic cultures of the AM fungus Rhizophag
