INTRODUCTION Impaired heart rate variability (HRV) is associated with poor outcome in diabetic patients. The present prospective study compared spectral components of HRV obtained by either fast Fourier transform (FFT) or autoregressive (AR) analyses in diabetic patients. METHODS Thirty patients (49+/-12 years; 11 F/19 M; 60% with insulin-dependent type 1 diabetes) underwent 24-h ambulatory e...

OBJECTIVE The relationship between serum testosterone (T) levels, muscle mass and muscle force in eugonadal men is incompletely understood. As polymorphisms in the androgen receptor (AR) gene cause differences in androgen sensitivity, no straightforward correlation can be observed between the interindividual variation in T levels and different phenotypes. Therefore, we aim to investigate the re...

OBJECTIVE Transitions in the spectrum of valvular heart diseases (VHDs) in developed countries over the 20th century have been reported from clinical case series, but large, contemporary population-based studies are lacking. METHODS We used nationwide registers to identify all patients with a first diagnosis of VHD at Swedish hospitals between 2003 and 2010. Age-stratified and sex-stratified ...

normal 0 false false false en-us x-none ar-sa microsoftinternetexplorer4 background: sex-related differences in the severity of multiple sclerosis (ms) could be influenced by the sex hormones. materials and methods: this cohort (historical) study evaluated the sex hormone levels during menstrual cycle and their correlation with disease severity in ms. result: patients with ms had significantly ...

The role of artificially created defects and steps in the local reaction kinetics of CO oxidation on the individual domains of a polycrystalline Pd foil was studied by photoemission electron microscopy (PEEM), mass spectroscopy (MS), and scanning tunneling microscopy (STM). The defects and steps were created by STM-controlled Ar+ sputtering and the novel PEEM-based approach allowed the simultan...

sublingual allergen immunotherapy (slit) is considered to be safer and more convenient than subcutaneus immunotherapy. slit trials with house dust mites involving patients with allergic rhinitis (ar) and asthma reported discordant results. the aim of the study was to investigate the clinical efficacy and safety of slit with dermatophagoides pteronyssinus (d.pt) extract produced in serbia and pa...

Spectral and cross-spectral analysis of R-R interval and systolic arterial pressure (SAP) spontaneous fluctuations have been proposed for noninvasive evaluation of baroreflex sensitivity (BRS). However, results are not in good agreement with clinical measurements. In this study, a bivariate parametric autoregressive model with exogenous input (ARXAR model), able to divide the R-R variability in...
