In this article, we demonstrate a method for inducing reversible crystal-to-crystal transitions in binary mixtures of soft colloidal particles. Through a controlled decrease of salinity and increasingly dominating electrostatic interactions, a single sample is shown to reversibly organize into entropic crystals, electrostatic attraction-dominated crystals, or aggregated gels, which we quantify usi
Ethanolamines are often added in the empirical formulation of commercial hard-surface cleaners and degreasers. Their use is usually justified by the fact they are anti-corrosive agents. However, their direct influence on cleaning performance is not well understood. In this work the cleaning performance of formulations with and without mono-ethanolamine (MEA) have been tested on standard polymerize
Background: Peritonitis is the leading cause of morbidity for peritoneal dialysis (PD) patients, and microbial biofilms have previously been identified on catheters from infected patients. However, few studies of catheters from patients without clinical signs of infection have been undertaken. The aim of the present study was to investigate the extent to which bacteria are present on catheters fro
Selecting the appropriate analytical methods for characterizing the assembly and morphology of polymer-based vesicles, or polymersomes are required to reach their full potential in biotechnology. This work presents and compares 17 different techniques for their ability to adequately report size, lamellarity, elastic properties, bilayer surface charge, thickness and polarity of polybutadiene-polyet
NETs (neutrophil extracellular traps) have been described as a fundamental innate immune defence mechanism. During formation of NETs, the nuclear membrane is disrupted by an as-yet unknown mechanism. In the present study we investigated the role of human cathelicidin LL-37 in nuclear membrane disruption and formation of NETs. Immunofluorescence microscopy revealed that 5 μM LL-37 significantly fac
Introduction: Systemic lupus erythematosus (SLE) is an autoimmune disease with chronic or episodic inflammation in many different organ systems, activation of leukocytes and production of pro-inflammatory cytokines. The heterodimer of the cytosolic calcium-binding proteins S100A8 and S100A9 (S100A8/A9) is secreted by activated polymorphonuclear neutrophils (PMNs) and monocytes and serves as a seru
Two new solvates were prepared in the system Cu(I) I using a solvolysis reaction. The structures for both of them were solved by X-ray crystallography, showing that they constitute two modifications of the same compound with the net formula [Cu4I6](P(C6H5)(4))(2)center dot 2OC(CH3)(2). Both types of crystals show vivid fluorescence when exposed to UV light. The formation of the first modification
A novel approach to create macroporous cryogels (or gels synthesized at sub-zero temperatures) with increased mechanical strength is presented. The cryogels with unique double-continuous macroporous networks were prepared via sequential freezing-thawing, when the new cryogel was synthesized inside the interconnected macropores of the preformed or primary cryogel. The prepared double-continuous mac
Brevmall Announcement of post-doc scholarship at the Department of Clinical Science, Malmö. EPDR1, a novel human batokine regulating β cell metabolism and function EPDR1 is expressed in β cells and may increase under metabolic overload to tighten glycolysis-mitochondrial TCA cycle coupling and, consequently, increasing GSIS. We aim to deepen our understanding of EPRD1 regulation of β-cell metaboli

A nonintrusive three-dimensional trap for microscopic particles in a Liquid is described. The trap is based on acoustic radiation forces in an ultrasonic confocal standing-wave cavity. Experiments at 11 MHz demonstrate the concept and verify the theoretically calculated forces. Theoretical calculations for higher-frequency systems indicate a significant potential for low-rms-displacement trapping
Aim: Several studies have addressed the association between changes in the female sex hormones estrogen and progesterone levels and changes in parameters of periodontitis. In order to understand how these hormones affect periodontal health it is of major importance to obtain information on their physiological importance. We have previously shown that periodontal ligament cells (PDL cells) express
Convincing data has suggested that four and a half LIM domain 2 protein (FHL2) serves a key function in cancer cell metastasis and that microRNA (miR)-340-5p can regulate cancer cell migration. The current study hypothesized that targeting FHL2 expression by miR-340-5p in colon cancer may attenuate colon cancer cell migration and invasion. FHL2 expression was therefore assessed in colon cancer mic
Quantum computing with single instances of rare earth-ions doped into inorganic crystals shows great promise as a scalable design in the field of quantum information. A detectable and controllable single readout ion is necessary for the scheme proposed in Lund to work. Due to its short excited state lifetime and its cyclable 4f-5d transition, cerium has been deemed suitable for just this purpose.
Prolate model colloids with defined properties can be obtained by the stretching of spherical polymeric particles, which is well-known for polystyrene and poly(methyl methacrylate) latices. The present study aims to extend this approach to functional core-shell particles in order to achieve a new class of anisotropic colloidal materials where both the aspect ratio and the effective volume fraction
In nature, bacteria usually exist as mixed-species biofilms, where they engage in a range of synergistic and antagonistic interactions that increase their resistance to environmental challenges. Biofilms are a major cause of persistent infections, and dispersal from initial foci can cause new infections at distal sites thus warranting further investigation. Studies of development and spatial inter
Objective: Constant exposure of pancreatic islets to high levels of glucose or free fatty acids can lead to irreversible beta-cell dysfunction, a process referred to as glucotoxicity or lipotoxicity, respectively. In this context a role for nitric oxide generated by pancreatic islet has been suggested. The present investigation examined whether the route of glucose administration, i.e., given oral
