It is generally well accepted that eukaryotes evolved from the symbiosis of an archaeal host cell and an alphaproteobacterium, a union that ultimately gave rise to the complex, eukaryotic cells we see today. However, the catalyst of this merger, the exact nature of the cellular biology of either partner, or how this event spawned the vast majority of complex life on Earth remains enigmatic. In rec

The influence of temperature and salt concentration on the properties of solid polymer electrolytes based on lithium bis(trifluoromethylsulfonyl)imide (LiTFSI) complexed by combshaped polyethers has been studied. The combshaped polyethers consisted of styrenic backbone polymers carrying pendant poly(ethylene oxide) (PEO) or poly(ethylene oxide-co-propylene oxide) (PEOPO) side chains terminated by

The presence of ribonucleic acid hairpin structures is important for proper processing of the genetic information in living cells. Recent studies indicate that interactions between platinum based anticancer active metal complexes and hairpin motifs result in a change of their three-dimensional structure combined with a decrease of the melting temperature. We here report a study of the reaction bet

EPR spectroscopy has been employed to determine the nature of vanadium (+4) species in the TiO2(B)-supported vanadia catalysts. IR and EPR studies show that multiple vanadia species are observed as a function of loading. At coverages greater than 3.5 theoretical layers, the EPR signal is reminiscent of bulk V205. At lower coverages, a different magnetic species dominates the resonance and may be a

Viral infection may trigger islet autoimmunity, type 1diabetes (T1D), or both. Fluctuating population density of bank voles as a putative reservoir of Ljungan virus has been claimed to be associated with variations in T1D incidence rate (IR). We tested the hypothesis that Ljungan virus antibodies reflecting prior exposure(s) to the virus may be associated with islet autoimmunity, childhood diabete

Abstract Therapeutic hypothermia has been shown to improve outcome in comatose survivors after cardiac arrest of cardiac origin. After the clinical implementation of this novel treatment, several international web-based registries were opened to facilitate the prospective collection of patient treatment data. The aim was to evaluate the actual use of hypothermia in clinical practice, safety aspect

Introduction: Interatrial frequency gradient is used to guide catheter ablation of atrial fibrillation (AF) but reliable tools for its non-invasive estimation are lacking. We present a patient with dissociated left and right atrial rhythms that allows identification of sum face ECG leads that closely reflect left atrial activity. Methods: 12-lead ECG was recorded simultaneously with electrograms f

Problem: The process of manufacturing corrugated board is a quite complicated process, when it comes to exactly understand what happens in the process. ln order to gain a better understanding and a tool for control of the corrugating process, the machine making the corrugated board, a method that possibly can describe the process is desirable. Throughout the thesis we are thus interested in findin
