Calculations of nuclear masses at finite angular momenta

The macroscopic-microscopic method to calculate nuclear masses is extended into the high-spin regime in order to calculate the nuclear binding energy as a function of proton number, neutron number and angular momentum. We describe the method and exemplify it on recent experimental data.

Saccharomyces cerevisiae RAP1 bind to telomeric sequences with spatial flexibility

A wide divergence has been detected in the telomeric sequences among budding yeast species. Despite their length and homogeneity differences, all these yeast telomeric sequences show a conserved core which closely matches the consensus RAP1-binding sequence. We demonstrate that the RAP1 protein binds this sequence core, without involving the diverged sequences outside the core. in Saccharomyces ca

Between-year variation of MHC allele frequencies in great reed warblers: selection or drift?

The major histocompatibility complex (MHC) genes are extremely polymorphic and this variation is assumed to be maintained by balancing selection. Cyclic interactions between pathogens and their hosts could generate such selection, and specific MHC alleles or heterozygosity at certain MHC loci have been shown to confer resistance against particular pathogens. Here we compare the temporal variation

Transmetallation reactions involving group 10 metals

This review gives an overview of the early development of transmetallation reactions for synthetic purposes and presents some recent results on the transmetallation reaction as a part of cross-coupling reactions and the mechanism of these reactions.

Experimental weathering of biotite, muscovite and vermiculite: a Mossbauer spectroscopy study

Biotite, muscovite and vermiculite were treated in HCl and H2SO4 solutions at pH ranging between 7 and 1. The solid residue was studied using Mossbauer spectroscopy at room temperature. The spectra of the untreated samples, D0Bio, D0Mus and DOVer were fitted assuming quadrupole splitting distribution, QSD. Different fitting models with different combinations of Gaussian components for the Fe sites

The effect of unfractionated and low-molecular-weight heparin on the release of prostacyclin from the arterial wall

Heparin is widely used as an antithrombotic agent, but one reported complication is thrombocytopenia associated with platelet aggregation. The mechanism is not fully clear but heparin interference in the prostaglandin production has been proposed. To investigate if heparin interacts with the production of prostacyclin from the vessel wall, and if low-molecular-weight heparin differs from unfractio

Human antibody response towards the pneumococcal surface proteins PspA and PspC during invasive pneumococcal infection.

gG antibodies against pneumococcal surface protein A, family 1 (PspAl) and family 2 (PspA2), protein C (PspC), and protein Hic were investigated in 41 patients with invasive pneumococcal disease. Pre-existing antibody levels against the four pneumococcal proteins were not significantly different from those found in 40 patients with non-pneumococcal bacteremia or 80 healthy controls. However, durin

Ballistic imaging of the liquid core for a steady jet in crossflow

A time-gated ballistic imaging instrument is used to obtain high-spatial-resolution, single-shot images of the liquid core in a water spray issuing into a gaseous crossflow. We describe further development of the diagnostic technique to improve spatial resolution and present images and statistics for various jets under crossflow experimental conditions (different Weber numbers). Series of these im

Artificial neural networks for rapid WWTP performance evaluation: Methodology and case study

Reliable performance evaluation of wastewater treatment plants (WWTPs) can be done by simulating the plant behavior over a wide range of influent disturbances, including series of rain events with different intensity and duration, seasonal temperature variations, holiday effects, etc. Such simulation-based WWTP performance evaluations are in practice limited by the long simulation time of the mech

Red cell sodium-potassium adenosine triphosphatase sites and intracellular sodium increased in obese school children

Principally to ascertain whether mineral metabolism is involved in weight regulation, the 40 most obese of 1,774 children, aged 10-11 years, screened for obesity were compared with 46 age-matched controls. The obese children had more 3H-Ouabain erythrocyte binding sites (p = 0.04), higher intracellular sodium (p = 0.04), and lower plasma sodium (p = 0.002). After exclusion of the non-Scandinavians

Effects of chronic citalopram treatment on central and peripheral spontaneous open-field behaviours in rats

The spontaneous open-field behavioural effects of 10 days of chronic treatment with two clinical doses (10 and 20 mg/kg daily) and one high/toxic dose (100 mg/kg daily) of the selective serotonin reuptake inhibitor citalopram (delivered subcutaneously by implanted osmotic pumps) were examined in rats. Central and peripheral arena locomotor and rearing activities were recorded simultaneously, and t

Supported liquid membranes in hollow fiber liquid-phase microextraction (LPME) - Practical considerations in the three-phase mode

In this work, three-phase liquid-phase microextraction (LPME) based on a supported liquid membrane (SLM) sustained in the wall of a hollow fiber was investigated with special focus on optimization of the experimental procedures in terms of recovery and repeatability. Recovery data for doxepin, amitriptyline, clomipramine, and mianserin were in the range of 67.8-79.8%. Within-day repeatability data

A high prevalence of organ-specific autoimmunity in patients with bipolar disorder.

BACKGROUND: In a previous study, we reported an increased prevalence of thyroperoxidase antibodies (TPOA) in patients with bipolar disorder. Here we report the prevalence of other organ-specific autoantibodies: H/K adenosine triphosphatase (ATPA), glutamic acid decarboxylase-65 (GAD65A), and GAD-67 (GAD67A). METHODS: ATPA, GAD65A, and GAD67A were determined (via a commercially available enzyme lin

Bcl-2 but not FOXP1, is an adverse risk factor in immunochemotherapy-treated non-germinal center diffuse large B-cell lymphomas

Non-germinal center (non-GC) phenotype, high level expression of the transcription factor forkhead box protein P1 (FOXP1) and anti-apoptotic protein Bcl-2 have been identified as unfavorable prognostic factors for diffuse large B-cell lymphoma (DLBCL) patients treated with chemotherapy. Our aim was to re-evaluate the prognostic impact of these biologic factors on the survival of the patients treat

Herbivory on aquatic vascular plants by the introduced golden apple snail (Pomacea canaliculata) in Lao PDR

The effect of naturally found densities of the exotic and herbivorous golden apple snail (Pomacea canaliculata) on three dominant aquatic plants - duckweed (Lemna minor), water hyacinth (Eichhornia crassipes) and morning glory (Ipomoea aquatica) - was assessed in a wetland survey and quantified in a field experiment in Laos in southeast Asia. Snail grazing reduced plant biomass, but plant species

Arabidopsis MYB68 in development and responses to environmental cues. Plant Science 167:

The Arabidopsis MYB68 gene encodes a MYB family protein with N-terminal R2R3 DNA-binding domains. Analyses of MYB68 expression by RNA blot and a transposant gene-trap MYB68::GUS reporter indicated that MYB68 is expressed specifically in root pericycle cells. Root cultures of the myb68 mutant, caused by the gene trap insertion in the first MYB68 exon, produced increased biomass and lignin levels co
