Hormone therapy and coronary heart disease risk by vasomotor menopausal symptoms.

OBJECTIVES: We examined whether the association between hormone therapy (HT) use and coronary heart disease (CHD) risk differed between women with and without vasomotor symptoms (VMS). STUDY DESIGN: We used data from a Dutch (EPOS) and Swedish (WHILA) population-based sample of 8865 women, aged 46-64 years, and free of CHD, stroke, venous thrombosis/pulmonary embolism or cancer at baseline. Data o

Plasma assisted combustion: Effects of O3 on large scale turbulent combustion studied with laser diagnostics and Large Eddy Simulations

Abstract In plasma-assisted combustion, electric energy is added to the flame where the electric energy will be transferred to kinetic energy of the free electrons that, in turn, will modify the combustion chemical kinetics. In order to increase the understanding of this complex process, the influence of one of the products of the altered chemical kinetics, ozone (O3), has been isolated and studie

Recent radiation in a marine and freshwater dinoflagellate species flock.

Processes of rapid radiation among unicellular eukaryotes are much less studied than among multicellular organisms. We have investigated a lineage of cold-water microeukaryotes (protists) that appear to have diverged recently. This lineage stands in stark contrast to known examples of phylogenetically closely related protists, in which genetic difference is typically larger than morphological diff

Fv structure of monoclonal antibody II-481 against herpes simplex virus Fc gamma-binding glycoprotein gE contains immunodominant complementarity determining region epitopes that react with human immunoglobulin M rheumatoid factors

Human immunoglobulin M (IgM) rheumatoid factors (RFs) show primary direct enzyme-linked immunosorbent assay (ELISA) reactivity with Fab rather than Fc fragments of monoclonal antibody (mAb) II-481 directed against the Fc gamma-binding site of herpes simplex virus glycoprotein gE. This preferential anti-Fab specificity suggests that RFs react with antigen-binding portions of mAb II-481 as anti-idio

Serum uric acid in traditional Pacific Islanders and in Swedes.

Background. In some western populations, increased serum uric acid has been positively associated with cardiovascular disease, possibly because hyperuricaemia could be an untoward part of the insulin-resistant metabolic syndrome. However, there is evidence that uric acid is a free radical scavenger capable of inhibiting LDL oxidation. Amongst the traditional horticulturalists of Kitava, Trobriand

Broad band synthetic seismograms for a spherical inhomogeneity in a many-layered elastic half-space

The propagation of elastic waves in a many-layered elastic half-space is considered. One of the layers contains a bounded inhomogeneity which in the numerical applications is taken as a sphere. The half-space is excited by an explosion, modelled as a sudden isotropic point source. First the time-harmonic problem is solved using the null field approach (the T-matrix method). Starting from surface

When binding matters: An ERP analysis of the development of recollection and familiarity in childhood

Dual process models of recognition memory assume that memory retrieval can be based on two distinct processes: an assessment of a context-free feeling of familiarity or on the reinstatement of specific context attributes that have been bound together to form a representation of the study episode during encoding (recollection). Recent neurophysiological evidence suggests that familiarity and recoll

Intramolecular dynamics of low molecular weight protein tyrosine phosphatase in monomer-dimer equilibrium studied by NMR: A model for changes in dynamics upon target binding

Low molecular weight protein tyrosine phosphatase (LMW-PTP) dimerizes in the phosphate-bound state in solution with a dissociation constant of K-d = 1.5(+/-0.1) mM and an off-rate on the order of 10(4) s(-1).H-1 and N-15 NMR chemical shifts identify the dimer interface, which is in excellent agreement with that observed in the crystal structure of the dimeric S19A mutant. Two tyrosine residues of

Phenotypic modulation of cultured bladder smooth muscle cells and the expression of inducible nitric oxide synthase.

Phenotypic modulation of smooth muscle is associated with various pathological conditions, including bladder dysfunction. Cytoskeletal dynamics modulate the cell phenotype and were recently shown to be involved in regulation of inducible nitric oxide synthase ( iNOS). We tested the hypothesis that the cell differentiation status affects iNOS expression, and that iNOS is preferentially expressed in

Some medical and biological applications of ultrafast lasers

Ultrafast lasers are finding many applications in medicine and biology. Pulses from such systems can be used directly or after non-linear modification. Direct utilisation includes time-resolved fluorescence spectroscopy and imaging. Such studies can be performed for tissue diagnosis in the field of malignant diseases as well as in the cardiovascular sector. Two-photon induced fluorescence provides

Integration of machine learning with phase field method to model the electromigration induced Cu6Sn5 IMC growth at anode side Cu/Sn interface

Currently, in the era of big data and 5G communication technology, electromigration has become a serious reliability issue for the miniaturized solder joints used in microelectronic devices. Since the effective charge number (Z*) is considered as the driving force for electromigration, the lack of accurate experimental values for Z* poses severe challenges for the simulation-aided design of electr

Decade of experimental permafrost thaw reduces turnover of young carbon and increases losses of old carbon, without affecting the net carbon balance

Thicker snowpacks and their insulation effects cause winter‐warming and invoke thaw of permafrost ecosystems. Temperature‐dependent decomposition of previously frozen carbon (C) is currently considered one of the strongest feedbacks between the Arctic and the climate system, but the direction and magnitude of the net C balance remains uncertain. This is because winter effects are rarely integrated

3D Structure and Mechanics of Silk Sponge Scaffolds Is Governed by Larger Pore Sizes

Three-dimensional scaffolds play an essential role in tissue engineering. Although essential, the tunability of the 3D scaffolds mechanical and transport properties remains a challenge. In this work, we present new approaches to advance the field. First, we applied our progressive pH acidification to mimic the natural silk gelation process before ice-templating (−20 and −80°C); second, we fitted t

Quantitative study of coherent pairing modes with two-neutron transfer : Sn isotopes

Pairing rotations and pairing vibrations are collective modes associated with a field, the pair field, which changes the number of particles by two. Consequently, they can be studied at profit with the help of two-particle transfer reactions in superfluid and in normal nuclei, respectively. The advent of exotic beams has opened, for the first time, the possibility to carry out such studies in medi

Quantification of tool wear mechanisms in machining : the case of controlled-microstructure AISI 316L

Tool wear intensity is one of the major performance and economic indicators of metal cutting processes. Understanding and control of tool wear and its governing mechanisms enables effective and sustainable manufacturing. Known wear mechanisms include abrasive, adhesive, chemical and diffusional, where their individual or combined action leads to an overall tool degradation. In this study, we prese

Statin use and risk of breast cancer among women with benign breast disease : a Danish nationwide cohort study

BACKGROUND: Statins have been suggested to protect against breast cancer risk, but the observational evidence is inconclusive. We examined the association between statin use and breast cancer incidence among women at higher risk of breast cancer due to a history of benign breast disease (BBD).METHODS: Using Danish registries, we identified cancer-free women aged ≥50 years during 1996-2018 with a h

Plasma 25-Hydroxyvitamin D Levels and Survival in Stage III Colon Cancer : Findings from CALGB/SWOG 80702 (Alliance)

PURPOSE: To assess whether higher plasma 25-hydroxyvitamin D [25(OH)D] is associated with improved outcomes in colon cancer and whether circulating inflammatory cytokines mediate such association.EXPERIMENTAL DESIGN: Plasma samples were collected from 1,437 patients with stage III colon cancer enrolled in a phase III randomized clinical trial (CALGB/SWOG 80702) from 2010 to 2015, who were followed

Tundra landscape heterogeneity, not interannual variability, controls the decadal regional carbon balance in the Western Russian Arctic

Across the Arctic, the net ecosystem carbon (C) balance of tundra ecosystems is highly uncertain due to substantial temporal variability of C fluxes and to landscape heterogeneity. We modeled both carbon dioxide (CO2) and methane (CH4) fluxes for the dominant land cover types in a ~100-km2 sub-Arctic tundra region in northeast European Russia for the period of 2006–2015 using process-based biogeoc
