Objective Blood pressure variability (BPV) has been associated with risk of cardiovascular events in observational studies, independently of mean BP levels. In states with higher autonomic imbalance, such as in diabetes, the importance of BP variability may theoretically be even greater. We aimed to investigate the incremental value of BPV for prediction of cardiovascular and all-cause mortality i

The Bit Flipping algorithm is a hard decision decoding algorithm originally designed by Gallager in 1962 to decode Low Density Parity Check Codes (LDPC). It has recently proved to be much more versatile, for Moderate Parity Check Codes (MDPC) or Euclidean metric. We further demonstrate its power by proposing a noisy Euclidean version of it. This tweak allows to construct a lattice based key exchan

Popular Abstract in Swedish Avhandlingen undersöker naturumgängets modernisering i Förenade Arabemiraten, en federation av sju shejkdömen på den arabiska sidan av Persiska Viken. De traditionella näringarna var handel, pastoralism, fiske och pärlfiske, men dessa har sedan 1960-talet ersatts av en ekonomi baserad på export av fossila bränslen. Landet har under kort tid övergått från att vara ett trThe thesis investigates human-environmental relations in the rapidly modernizing United Arab Emirates, a federation of seven Arabian Gulf sheikhdoms. Since its establishment in 1971, the UAE has been transformed from a subsistence society based mainly on pastoralism and maritime activities (fishing, pearling, and trade) into an ultramodern society, with an economy based on the export of fossil fue

The location of lipoprotein lipase activity in rat adipose tissue was studied using intact epididymal fat pads, isolated adipocytes, and lipoprotein lipase activity secreted from adipocytes as enzyme sources. The enzyme activities of these preparations were characterized by gel filtration. The method used for isolation of adipocytes had been modified to minimize activation of lipoprotein lipase du

Background: It has been suggested that exhaled breath temperature (EBT) is increased in asthmatic subjects. Objectives: Our aim was to investigate EBT in asthmatics compared to healthy controls before and after eucapnic voluntary hyperventilation (EVH) and a methacholine challenge test (MCT). Methods: A total of 26 asthmatics and 29 healthy controls were included. Forced expiratory volume in 1 s (

The honeybee is one of several insect model systems for the study of olfaction, yet our knowledge regarding the spectrum of odorants detectable by Apis mellifera is limited. One class of odorants that has never been tested so far are the amino acids, which are important constituents of floral nectar. Using the proboscis extension response paradigm, we assessed whether the odor of amino acids is de

OBJECTIVES: To describe changes in physical activity levels related to health-enhancing physical activity guidelines during and after adjuvant chemotherapy in a cohort of Swedish patients with breast cancer. DESIGN: Exploratory clinical prospective longitudinal study with 6 and 12 months of follow-up. PARTICIPANTS: Forty women treated for breast cancer with adjuvant chemotherapy were included, and

Inherited resistance to activated protein C (APC resistance) is an important risk factor of venous thrombosis. It is caused by a point mutation in the gene coding for coagulation factor V, called FV:Q506. Arterio-venous thrombosis is a common and serious medical problem in patients with systemic lupus erythematosus (SLE). We studied the prevalence of the factor V mutation associated with APC resis

Aim: To evaluate three types of ventilation systems for operating rooms with respect to air cleanliness [in colony-forming units (cfu/m3)], energy consumption and comfort of working environment (noise and draught) as reported by surgical team members. Methods: Two commonly used ventilation systems, vertical laminar airflow (LAF) and turbulent mixed airflow (TMA), were compared with a newly develop

Thirty-four patients with traumatic distractive flexion injuries in the mid to lower cervical spine were treated with posterior wire stabilization without bony fusion from January 1981 through May 1987. Fifteen had cord involvement, and nine had root involvement. Ten were neurologically intact. Thirty patients were followed for a mean of 38 months. Two neurologically intact patients had root defic

Electronic and spin structure of the Dirac-cone-like topological surface and valence band states were studied experimentally and theoretically for topological insulator with fractional stoichiometry Bi1.5Sb0.5Te1.8Se1.2 which is considered as one of the best candidates for efficient spin-polarized current generation. By means of spin- and angle-resolved photoelectron spectroscopy we demonstrate th

Primary defence against invading microorganisms depends on a functional innate immune system and the complement system plays a major role in such immunity. Deficiencies in one of the components of the complement system can cause severe and recurrent infections, systemic diseases, such as systemic lupus erythematosus (SLE) and renal disease. Screening for complement deficiencies in the classical or

Objective: Apart from improved health outcomes, treatment convenience per se may have a value to individuals. This is sometimes referred to as process utility and can be estimated in terms of willingness-to-pay (WTP) or quality-adjusted life-years (QALYs). Previous research has produced multiple studies on QALY gains and WTP estimates of insulin-related attributes. There are, however, significant

In a case-control study of 280 out of 426 consecutive patients with a recent diagnosis of non-Hodgkin lymphoma (NHL) and 1827 control subjects, 53 (19%) and 230 (13%) respectively had received blood transfusions 1 year or more before the interview. Using an age- and sex-stratified analysis the odds ratio (OR) for transfusion was 1.74 (95% CI 1.24-2.44). ORs were also determined for transfusions re

If we take recent income per capita estimates at face value, they imply that the average medieval European was at least five times ‘better off’ than the average Congolese today. This raises important questions regarding the meaning and applicability of national income estimates throughout time and space, and their use in the analysis of global economic history over the long term.
