Synergism between a novel chimeric lysin and oxacillin protects against infection by methicillin-resistant Staphylococcus aureus
Staphylococcus aureus is the causative agent of several serious infectious diseases. The emergence of antibiotic-resistant S. aureus strains has resulted in significant treatment difficulties, intensifying the need for new antimicrobial agents. Toward this end, we have developed a novel chimeric bacteriophage (phage) lysin that is active against staphylococci, including methicillin-resistant S. au
On the Growth of Bone through Stress Driven Diffusion and Bone Generation Processes
För att bättre kunna förebygga att skelettet bryts ner vid långvarig vila eller vid sjukdomarsom osteopenia och osteoporos, behövs bättre förståelse för de processer somstyr detta. I den här avhandlingen antas att den primära orsaken till bentillväxt är enförändring i den kemiska miljön i benet. Förändringen antas orsakas av att tillväxtstimulerandeämnen transporteras genom benet till den plats däIn order to prevent or modify bone degeneration due to rest or due to diseases such as osteopenia and osteoporosis, the modeling and remodeling of bone tissue must be better understood. In this thesis it is assumed that the primary condition leading to bone growth is a change of the chemical environment caused by transport of matter resulting from stress driven diffusion. The change in the chemica
Sri Lanka: as constitutional crisis triggers fears of ‘bloodbath’, concern mounts for minorities
Ett nytt cellskelett i kampen mot cancer
Forskare vid Lunds universitet har upptäckt ett cellskelett som ger struktur åt mito-kondrierna, cellens energifabriker. Skelettet är nödvändigt för mitokondriernas funktion, men forskarna fann även att cancerceller trots defekter utnyttjar skelettet för att kunna bibehålla sin energiproduktion – och därigenom överleva. Cellskelettet i mitokondrierna fungerar ungefär som ett armeringsnät och hjälp
Gamma-tubules — novel filaments in the fight against cancer
The word skeleton sounds very significant, and indeed humans could not exist without a skeleton! Similarly, a cellular skeleton or cytoskeleton is crucial for the functions of a cell. Several different types of cytoskeleton have been identified that are necessary, for among other things, muscle movement and the activities of the brain, and consequently humans could not function at all without cytosk
Report of the international conference on manufacturing and testing of pluripotent stem cells
Sessions included an overview of past cell therapy (CT) conferences sponsored by the International Alliance for Biological Standardization (IABS). The sessions highlighted challenges in the field of human pluripotent stem cells (hPSCs) and also addressed specific points on manufacturing, bioanalytics and comparability, tumorigenicity testing, storage, and shipping. Panel discussions complemented t
κλώταξ och κνώδαξ: ett sällsynt ord och dess synonym
Ordet κλώταξ är känt från en enda bevarad antik grekisk text, Kosmas Indikopleustes’ Topographia Christiana, där det förekommer sammanlagt fyra gånger. Översättare och lexikografer har haft besvär med ordet. Detta är ett försök att närmare precisera dess betydelse samt att göra det troligt att κλώταξ är synonymt med det något vanligare κνώδαξ.
Genetic and environmental factors affecting birth size variation : A pooled individual-based analysis of secular trends and global geographical differences using 26 twin cohorts
Background: The genetic architecture of birth size may differ geographically and over time. We examined differences in the genetic and environmental contributions to birthweight, length and ponderal index (PI) across geographical-cultural regions (Europe, North America and Australia, and East Asia) and across birth cohorts, and how gestational age modifies these effects. Methods: Data from 26 twin
Graphene and 2D-Like Nanomaterials : Different Biofunctionalization Pathways for Electrochemical Biosensor Development
In the last decades, nanotechnology has played a key role in the electrochemical biosensor development based on the mediated and direct electrochemical communication between the biorecognition elements and the electrode surface. In particular, graphene and 2D-like nanomaterials (e.g., boron nitride nanosheets, graphitic carbon nitride (g-C3N4) nanosheets, and various transition metal dichalcogenid
Evolution from γ -soft to stable triaxiality in Nd 136 as a prerequisite of chirality
The level structure of Nd136 has been investigated using the Mo100(Ar40,4n) reaction and the JUROGAM II+RITU+GREAT setup. The level scheme has been extended significantly. Many new bands have been identified both at low and high spin, among which are five nearly degenerate bands interpreted as chiral partners. Excitation energies, spins, and parities of the previously known bands are revised and f
Changes in f-wave characteristics during cryoballoon catheter ablation
OBJECTIVE: Changes in ECG-derived parameters are studied in atrial fibrillation (AF) patients undergoing cryoballoon catheter ablation.APPROACH: Parameters characterizing f-wave frequency, morphology by phase dispersion, and amplitude are estimated using a model-based statistical approach. These parameters are studied before, during, and after ablation, as well as for AF type (paroxysmal/persisten
Study protocol for an observational register-based study on health and risk factors in patients with hip and knee osteoarthritis
INTRODUCTION: Hip and knee osteoarthritis is a leading cause of disability worldwide. Currently, the course of deterioration in pain and physical functioning in individuals with osteoarthritis is difficult to predict. Factors such as socioeconomic status and comorbidity contribute to progression of osteoarthritis, but clear associations have not been established. There is a need for early identifi
Socioeconomic position, symptoms of depression and subsequent mental healthcare treatment : a Danish register-based 6-month follow-up study on a population survey
OUTCOMES: MHCT included number of contacts with: general practitioner (GP), GP mental health counselling, psychologist, psychiatrist, emergency contacts, admissions to psychiatric hospitals and prescriptions of antidepressants.OBJECTIVE: Examine whether the severity of symptoms of depression was associated with the type of mental healthcare treatment (MHCT) received, independent of socioeconomic p

Dental Implant Quality Register—A possible tool to further improve implant treatment and outcome
The Board of EAO (European Association for Osseointegration) has discussed an initiative to explore the conditions to establish a Dental Implant Register. It was suggested to bring this issue to the EAO Consensus Conference 2018 for a discussion and to possibly propose relevant and manageable parameters. This article presents some select examples from quality registers in the medical field. Based
The Tycho-Gaia Astrometric Solution
Gaia DR1 is based on the first 14 months of Gaia's observations. This is not long enough to reliably disentangle the parallax effect from proper motion. For most sources, therefore, only positions and magnitudes are given. Parallaxes and proper motions were nevertheless obtained for about two million of the brighter stars through the Tycho-Gaia astrometric solution (TGAS), combining the Gaia obser
GaiaNIR - A future all-sky astrometry mission
With the launch of Gaia in December 2013, Europe entered a new era of space astrometry following in the footsteps of the very successful Hipparcos mission. A weakness of Gaia is that it only operates at optical wavelengths. However, much of the Galactic centre and the spiral arm regions are obscured by interstellar extinction. An obvious improvement on Gaia is to include the Near-Infra-Red (NIR) w
Optical properties of III-nitride semiconductors
The optical properties of the group-III-nitride materials are obviously of direct relevance for optoelectronic applications, but experiments measuring optical properties also give information on a range of electronic properties. There is already a wealth of data in the literature on the optical properties of III-nitrides [1-4], and here we will concentrate on some of the most recent additions to t
Transcription factor programming of human ES cells generates functional neurons expressing both upper and deep layer cortical markers
Human neurodegenerative disorders affect specific types of cortical neurons. Efficient protocols for the generation of such neurons for cell replacement, disease modeling and drug screening are highly warranted. Current methods for the production of cortical neurons from human embryonic stem (ES) cells are often time-consuming and inefficient, and the functional properties of the generated cells h
