UNLABELLED Aberrant waveform during artificial pacing increases secretion of natriuretic peptides, mainly B-type natriuretic peptide (BNP). The aim of the study was to investigate whether renal function is modified through increased BNP secretion during artificial pacing. MATERIAL AND METHODS A total of 117 patients with pacemaker implanted were included (pacing mode: AAI/R - 21, DDD/R - 59, ...

Constant dielectric (CD) and distance-dependent dielectric (DDD) functions are the most popular and widespread in the Molecular Mechanics simulations of large molecular systems. In this article, we present a simple procedure to derive an effective dielectric constant, epsilon (out,eff), for these two methods based on numerical solutions of the Poisson equation. It was found that because of the ...

BACKGROUND Resistance to antibiotics is a major public-health problem and antibiotic use is being increasingly recognised as the main selective pressure driving this resistance. Our aim was to assess outpatient use of antibiotics and the association with resistance. METHODS We investigated outpatient antibiotic use in 26 countries in Europe that provided internationally comparable distributio...

The urinary metabolites of 1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane (DDT), 1,1-dichloro-2,2-bis(p-chlorophenyl)ethane (DDD), and 1-chloro-2,2-bis(p-chlorophenyl)ethene in female hamsters are reported. The principal metabolite of both DDT and DDD is 2,2-bis(p-chlorophenyl) acetic acid. DDT- and DDD-treated animals also excreted small amounts of DDD, 1-chloro-2,2-bis(p-chlorophenyl)ethene, 1...

Objective: To determine how short and long term complication rates after pacemaker implantation are influenced by patient morbidity, operator experience, and choice of pacing system. Design: Retrospective analysis of 1884 patients who received VVI (n = 610), VDD (n = 371), or DDD devices (n = 903) between 1990 and 2001. Follow up period was 64 (34) months. The influence of age, sex, coronary ar...

INTRODUCTION: Disc Degenerative Disease (DDD) is one of the most common causes of low back pain (LBP), to date; there is no one effective treatment of DDD. Artifical disc implantation have been proposed as a motion preservation solution to DDD. However, studies of artificial disc implants have suggested that the artificial discs causes permanent changes in the kinematics of the spine and cannot...

The concentrations of organochlorine pesticides (OCPs) and 16 priority polycyclic aromatic hydrocarbons (PAHs) were investigated in the sediments from Poyang Lake, the largest freshwater lake in China. The results showed that the total concentrations of four hexachlorocyclohexane (HCH) isomers (α-HCH, β-HCH, γ-HCH, δ-HCH), three dichlorodiphenyltrichloroethane (DDT) homologs and their metabolit...

Atrial fibrillation (AF) persists as the most challenging arrhythmia in clinical practice, and it currently affects an estimated 400 million people worldwide. We view AF as the most common sustained supraventricular tachyarrhythmia, for it is associated with extensive morbidity and mortality [1]. According to some studies, AF is responsible for numerous hospitalizations, which result in signifi...

Many neurons in the dorsal medial superior temporal (MSTd) and ventral intraparietal (VIP) areas of the macaque brain are multisensory, responding to both optic flow and vestibular cues to self-motion. The heading tuning of visual and vestibular responses can be either congruent or opposite, but only congruent cells have been implicated in cue integration for heading perception. Because of the ...

AIM OF DATABASE The purpose of the Danish Depression Database (DDD) is to monitor and facilitate the improvement of the quality of the treatment of depression in Denmark. Furthermore, the DDD has been designed to facilitate research. STUDY POPULATION Inpatients as well as outpatients with depression, aged above 18 years, and treated in the public psychiatric hospital system were enrolled. M...
