Cytokines play an important role in the regulation of homeostasis and inflammation. A de-regulated cytokine function can subsequently promote chronic inflammation. This is supported by clinical evidence showing the beneficial effect of inhibiting TNF-alpha through injection of antibodies and soluble receptor in disorders such as rheumatoid arthritis and Crohn's disease. Systemic anti-TNF-alpha the
A synthetic fluorapatite was prepared that undergoes a phase transformation generated during a dialysis step. A surface layer with the composition Ca(9)(HPO(4))(2)(PO(4))(4)F(2) is formed, which is suggested to form as one calcium atom is replaced by two protons. A surface complexation model, based upon XPS measurements, potentiometric titration data, batch experiments, and zeta-potential measurem
The dynamic soil model SAFE was calibrated and validated in a small hardwood forest of southern Quebec as a function of its ability to reproduce current soil chemistry and similar pre-industrial soil conditions despite the difference in forest history. SAFE was relatively accurate for reproducing soil chemistry, but comparison of pre-industrial soil conditions between unburned and burned stands ca
The essential protein Cdc13p binds the single-stranded telomeric 3' overhangs in Saccharomyces cerevisiae and takes part in the regulation of telomere length. The DNA-binding domain (DBD) of Cdc13p is structurally established by an oligonucleotide/oligosaccharide-binding (OB)-fold domain. The sequence homolog in Saccharomyces castellii (scasCDC13) was characterized previously, and the full-length
What does love have to do with gaming? As games have grown in complexity, they have increasingly included narratives that seek to engage players with love in a variety of ways. While media attention often focuses on violent emotions and behavior in gaming, love has always been central to the experience. We love to play games, we have titles that we love, and sometimes we love too much or love terr
Popular Abstract in Swedish Bildning, bearbetning och upplagring av cathepsin G, proteinas 3 och azurocidin - närbesläktade bakteriedödande proteiner i vita blodkroppar Människans kropp utsätts dagligen för fientliga attacker av olika sorters mikroorganismer, tillhörande bakterie-, virus- eller svampsläktet. Så länge vi är friska och vårt immunförsvar fungerar, kan vi som tur är framgångsrikt föThe neutrophil granulocyte contains a number of multifunctional proteins stored in different subsets of granules. The azurophil granules, synthesized early during differentiation, harbour leukocyte elastase, cathepsin G, proteinase 3, and azurocidin; the members of the serprocidin family. In order to study the biosynthesis, processing, and intracellular sorting of the proteins, human cDNA encoding
Talk in safety-critical activities displays features that distinguish it from both ordinary conversations as well as from other institutional talk, but it also shares some features with these. Formality and informality are both interactionally accomplished phenomena, although shaped through different sources. Safety rules and pre-printed forms constitute two sources of formalization, dictating how
Factor V (FV) serves an important role in the regulation of blood coagulation, having both pro- and anticoagulant properties. The circulating high molecular weight single-chain FV molecule undergoes a series of proteolytic cleavages during both activation of coagulation and during anticoagulant regulation of coagulation by activated protein C (APC). It is noteworthy that mutations in the factor V
Pathogenic mitochondrial DNA (mtDNA) mutations leading to mitochondrial dysfunction can cause cardiomyopathy and heart failure. These mutations were described in the mt-tRNA genes and in the mitochondrial protein-coding genes. The aim of this study was to identify the genetic defect in two patients belonging to two families with cardiac dysfunction associated to a wide spectrum of clinical phenoty
Receptors of the 5-HT2C subtype are assumed to be involved in the influence of serotonin on food intake. A polymorphism in the coding region of the gene for this receptor, resulting in a cysteine to serine substitution, has been reported. Fifty-seven somatically healthy teenage girls displaying weight loss and 91 normal-weight girls of the same age, all recruited by means of a population-based scr
Ostreopsis ovata is a benthic dinoflagellate that produces palytoxin and ovatoxins. Blooms of O. ovate causing human health problems and mortality of benthic fauna have been reported from many tropical and temperate marine waters. In the present study we examined the combined effects of temperature and different nutrient conditions on the biochemical composition, growth, toxicity and carbohydrate
Mitochondrial diseases involve the dysfunction of the oxidative phosphorylation (OXPHOS) system. This group of diseases presents with heterogeneous clinical symptoms affecting mainly organs with high energy demands. Defects in the multimeric complexes comprising the OXPHOS system have a dual genetic origin, mitochondrial or nuclear DNA. Although many nuclear DNA mutations involve genes coding for
Radome diagnostics are acquired in the design process, the delivery control and in performance verification of repaired and newly developed radomes. A measured near or far field may indicate deviations, e.g., increased side lobe levels, but the origin of the flaws are not revealed. In this paper, radome diagnostic is performed by visualizing equivalent currents on a radome surface. We localize pha
The legitimacy of the judiciary hinges on the presumption that truth can be found through the judicial process. Even though a distinction can be made between "truth" in a legal sense and "real truth", the legal truth can only be justified by its anchorage in "real truth". During the last few decades, the previosly all-powerful assumption of the objective nature of reality and knowledge has been ch
We study how the results of molecular dynamics (MD) simulations are affected by various choices during the setup, e.g., the starting velocities, the solvation, the location of protons, the conformation of His, Asn, and Gln residues, the protonation and titration of His residues, and the treatment of alternative conformations. We estimate the binding affinity of ligands to four proteins calculated
Moths depend on pheromone communication for mate finding and synthetic pheromones are used for monitoring or disruption of pheromone communication in pest insects. Here we produce moth sex pheromone, using Nicotiana benthamiana as a plant factory, by transient expression of up to four genes coding for consecutive biosynthetic steps. We specifically produce multicomponent sex pheromones for two spe
Context. The solution of the nonlocal thermodynamical equilibrium (non-LTE) radiative transfer equation usually relies on stationary iterative methods, which may falsely converge in some cases. Furthermore, these methods are often unable to handle large-scale systems, such as molecular spectra emerging from, for example, cool stellar atmospheres. Aims. Our objective is to develop a new method, whi
A set of B(E2) values for the low-lying excited states in the radioactive isotope Sn-109 were deduced from a Coulomb excitation experiment. The 2.87-MeV/u radioactive beam was produced at the REX-ISOLDE facility at CERN and was incident on a secondary Ni-58 target. The B(E2) values were determined using the known 2(+) -> 0(+) reduced transition probability in Ni-58 as normalization with the semicl
The specific insertion of a divalent metal ion into tetrapyrrole macrocycles is catalyzed by a group of enzymes called chelatases. Distortion of the tetrapyrrole has been proposed to be an important component of the mechanism of metallation. We present the structures of two different inhibitor complexes: (1) N-methylmesoporphyrin (N-MeMP) with the His183Ala variant of Bacillus subtilis ferrochelat
