Low Serum Testosterone and Estradiol Predict Mortality in Elderly Men.

Context: Age-related reduction of serum testosterone may contribute to the signs and symptoms of aging, but previous studies report conflicting evidence about testosterone levels and male mortality. No large prospective cohort study has determined a possible association between serum estradiol and mortality in men. Objective: The main objective was to examine the association between serum testoste

System-on-chip test scheduling with reconfigurable core wrappers

The problem with increasing test application time for testing core-based system-on-chip (SOC) designs is addressed with test architecture design and test scheduling. The scan-chains at each core are configured into a set of wrapper-chains, which by a core wrapper are connected to the test access mechanism (TAM), and the tests are scheduled in such a way that the test time is minimized. In this pap

Age‐related circulatory responses to whole body cooling: observations by heart rate variability

The purpose was to study potential age ‐ related changes in the circulatory system via heart rate variability (HRV) by gradually lowering ambient temperature (0.2°C/min) from thermoneutral (32 C°) towards cold (18 C°). ECG was recorded from a young (31 years) and from an older subject (78 years), both males. During the tests, brachium blood pressure (BP) was recorded. During the cooling, BP increa

Photoreceptor Function in School-Aged Children is Affected by Preterm Birth.

Prematurely born children have affected visual functions at school age. Optical coherent tomography (OCT) has shown morphological changes in the retina, suggesting a disturbance in normal retinal development in these children. The aim of this study was to examine retinal function with fullfield electroretinogram (ffERG) in school-aged children born prematurely and compare with children born at ter

Visualization and Simulation Technology in Healthcare - From a technology-centered to a human-centered perspective

Popular Abstract in Swedish I ett väderälskande land som Sverige finns det väl ingen som inte är bekant med den väderkarta som ger oss information om hur prognosen för den närmaste tiden ser ut? Många av oss tittar dagligen på väderrapporten och låter den hjälpa oss att bestämma om vi ska cykla eller ta bussen, sätta på grillen eller laga mat i ugnen. Genom enkla visualiseringar i form av sol, regWith the aid of modern computer technology the application of visualization and simulation technology has become increasingly important in today’s society. Through computer modelling it is possible to experience, understand and explore environments, systems or objects in two or three dimensions and to see, hear and sometimes tangibly feel them. It may be environments or objects that do not yet exi

Förmedlingstjänster för döva och hörselskadade

Detta är en förstudie genomförd på uppdrag av Post- och Telestyrelsen av förmedlingstjänster för döva och hörselskadade människor. Mycket talar för att det behövs fördjupade studier, men det går att peka på vissa tämligen uppenbara spår att vidareutveckla

Immune privilege of allogeneic neuroretinal transplants in the subconjunctival space.

BACKGROUND: The extent of site and tissue-associated immune privilege is of great interest in transplantation experiments involving the CNS. In the present paper we have explored neuroretinal immune privilege by transplantation to a non-immune privileged site. METHODS: Fetal and adult full-thickness rabbit neuroretinal grafts were placed in the subconjunctival space of immunocompetent rabbit hosts

Gut metabolites associated with pH and antioxidant capacity during in vitro colonic fermentation of Mexican corn products

Background and objectives: Food is the major factor driving the metabolism of the gut microbiota. In Mexico, nixtamalized corn products are widely consumed. Changes in antioxidant capacity (AOX) in 1,1-Diphenyl-2-picrylhydrazyl (DPPH) and Ferric ion reducing antioxidant power (FRAP), pH values, short-chain fatty acid concentration, and relative metabolite production during in vitro colonic ferment

Correlation of ST changes in leads V4–V6 to area of ischemia by CMR in inferior STEMI

Objective. We aim to determine the correlation between ST-segment changes in leads V4–V6 and the extent of myocardial injury by cardiac magnetic resonance (CMR) in patients with inferior ST elevation (STE) myocardial infarction (iSTEMI). Design. Admission electrocardiogram and CMR data from the MITOCARE trial were used. Differences in mean myocardium at risk, infarct size, ejection fraction and my

Occupational exposure to asphalt mixture during road paving is related to increased mitochondria DNA copy number : A cross-sectional study

Background: Asphalt workers are exposed to polyaromatic hydrocarbons (PAHs) from hot mix asphalt via both inhalation and dermal absorption. The use of crumb rubber modified (CRM) asphalt may result in higher exposure to PAHs and more adverse effects. Our aim is to assess occupational exposure to PAHs from conventional and CRM asphalt paving by measuring PAH metabolites in urine, and to investigate

Compact matrix factorization with dependent subspaces

Traditional matrix factorization methods approximate high dimensional data with a low dimensional subspace. This imposes constraints on the matrix elements which allow for estimation of missing entries. A lower rank provides stronger constraints and makes estimation of the missing entries less ambiguous at the cost of measurement fit. In this paper we propose a new factorization model that further

Parallel Evolution of Chromatin Structure Underlying Metabolic Adaptation

Parallel evolution occurs when a similar trait emerges in independent evolutionary lineages. Although changes in protein coding and gene transcription have been investigated as underlying mechanisms for parallel evolution, parallel changes in chromatin structure have never been reported. Here, Saccharomyces cerevisiae and a distantly related yeast species, Dekkera bruxellensis, are investigated be

High pT spectra and anisotropy of light and heavy hadrons

Data driven studies of heavy-ion results has played a big role in highlighting interesting features of these complex systems. In this proceeding, a simple QGP-brick interpretation of the RAA and v2 at high pT (pT≈10 GeV/c) is presented. This interpretation draws attention to two fundamental questions: is there an effect of the asymmetric QGP expansion on the v2 at high pT? is there an energy loss

Multiparton interactions : From pp to pA

In the process of understanding nuclear collisions, reliable extrapolations from pp collisions, based on Glauber models, are highly desirable, though seldomly accurate. We review the inclusion of diffractive excitations and argue that they provide an important contribution to centrality observables in pA collisions. We present a method for distinguishing between diffractively and non-diffractively

Influence of the steam addition on premixed methane air combustion at atmospheric pressure

Steam-diluted combustion in gas turbine systems is an effective approach to control pollutant emissions and improve the gas turbine efficiency. The primary purpose of the present research is to analyze the influence of steam dilution on the combustion stability, flame structures, and CO emissions of a swirl-stabilized gas turbine model combustor under atmospheric pressure conditions. The premixed
