Background and purpose: Heart failure (HF) is a serious issue concerning public health in all countries. Assessment and monitoring of mortality and influencing factors are of great importance in HF treatment programs. This study was conducted to determine the incidence of HF and the associated factors in Iran. Materials and methods: In this study, we did two main, independent analyses. One was...
Background and Aim: The aim of this study was to investigate the shear bond strengthof composite to Emax porcelain using different methods of ceramic surface preparation (in vitro). Material and Methods: In this laboratory study, 36 porcelain disks were made and divided into four equal groups. The first group was prepared by sandblasting with 50 micron alumina particles, in the second group rec...
Pyridostigmine bromide (PB) is a reversible cholinesterase inhibitor. The aim of this study was to determine the effect of orally administration of single dose sustained-released tablet of pyridostigmine bromide (PBSR) on the frequency domain indices of heart rate variability (HRV). Thirty-two healthy young men were participated in this study. They were divided into 2 groups; the pyridostigmine...
This paper presents a solution to increase the throughput of an HF (High Frequency) physical (PHY) layer in particular to allow for services such as IP over HF. Additionally, this new PHY layer can improve the adaptability of the waveform to the channel variations, in particular to limit the retransmissions due to errors. Taking into consideration the existing HF spectrum occupancy and its high...
Hyponatremia is a common clinical condition among hospitalized heart failure patients, associated with increased morbidity and mortality. The pathophysiological mechanisms that relate heart failure with hyponatremia are complex, involving beyond renal dysfunction, neurohormonal activation and diuretic treatment. The pituitary hormone vasopressin seems to play a central role leading to renal wat...
BACKGROUND The aim of the present study was to assess the utility of amino-terminal pro-A-type natriuretic peptide (NT-proANP) measurements for the emergency diagnosis of acute destabilized heart failure (HF), using a novel sandwich immunoassay covering midregional epitopes (MR-proANP). METHODS The retrospective analysis comprised 251 consecutive patients presenting to the emergency departmen...
Not only increasing body carbohydrate (CHO) stores before exercise but also suppressing CHO oxidation during exercise is important for improving endurance performance. We tested the hypothesis that intensive high-fat ingestion in the early stage of recovery from exercise training (ET) for 2 d would suppress CHO oxidation during exercise by increasing whole body lipolysis and/or fat oxidation. I...
OBJECTIVE Our aim was to study the therapeutic effects and the mechanism of combination of hemofiltration (HF) and peritoneal dialysis (PD) in the treatment of severe acute pancreatitis (SAP). METHODS Fifty-one cases of SAP were randomly divided into the HF+PD group (treated group, 36 patients) and the non-HF+PD group (control group, 15 patients). Both groups were treated by the same traditio...
AIM To determine whether brain natriuretic peptide (BNP)-guided heart failure (HF) treatment improves morbidity and/or mortality when compared with conventional treatment. METHODS AND RESULTS UPSTEP was an investigator-initiated, randomized, parallel group, multicentre study with a PROBE design. Symptomatic patients with worsening HF, New York Heart Association class II-IV, ejection fraction ...
Obesity is a risk factor for colorectal cancer (CRC), and alterations in the colonic microbiome and metabolome may be mechanistically involved in this relationship. The relative contribution of diet and obesity per se are unclear. We compared the effect of diet- and genetically-induced obesity on the intestinal microbiome and metabolome in a mouse model of CRC. Apc1638N mice were made obese by ...
