Introduction: Atrial arrhythmias in patients with sarcoidosis (Sar) are not unusual and can occur due to either atrial myocardial fibrosis and/or due to autonomic nervous system imbalance. Electrocardiographic markers (ECG), like maximum and minimum P wave duration and P wave dispersion {Pdis = Pmax − Pmin} reflect atrial depolarization inhomogeneity and can indicate patients prone to develop a...

BACKGROUND The oesophagus is the first gastrointestinal (GI) tract involved in systemic sclerosis (SSc), followed by the anorectum. OBJECTIVE Evaluation of oesophageal and anorectal involvement and their correlations in patients with very early diagnosis of SSc (VEDOSS). PATIENTS AND METHODS 59 patients with VEDOSS, evaluated with oesophageal and anorectal manometry and investigated with lu...

OBJECTIVE Prognosis in pulmonary hypertension (PH) is largely determined by RV function. However, uncertainty remains about what metrics of RV function might be most clinically relevant. The purpose of this study was to assess the clinical relevance of metrics of RV functional adaptation to increased afterload. METHODS Patients referred for PH underwent right heart catheterisation and RV volu...

Shop scheduling problems are known to be notoriously intractable, both in theory and practice. In this paper we give a randomized approximation algorithm for flow shop scheduling where the number of machines is part of the input problem. Our algorithm has a multiplicative factor of 2(1 + δ) and an additive term of O(m ln(m+ n)pmax)/δ ).

We state a sparse approximate version of the blow-up lemma, showing that regular partitions in sufficiently pseudorandom graphs behave almost like complete partite graphs for embedding graphs with maximum degree ∆. We show that (p, γ)-jumbled graphs, with γ = o(pmax(2∆,∆+3/2)n), are “sufficiently pseudorandom”. The approach extends to random graphs Gn,p with p ( log n n )1/∆.

The purpose of the present study was to determine whether extracellular osmotic pressure modulates beta2-adrenergic stimulation of the contraction force and L-type Ca2+ current in human atrial myocytes. Experiments were performed on human atrial trabeculae and myocytes isolated from the right atrium. We have studied the effect of salbutamol (SAL), a beta2-adrenoceptor agonist, on peak tension (...

1. Three common species of freshwater phytoplankton, the diatom Nitzschia sp., green alga Sphaerocystis schroeteri and cyanobacterium Phormidium luridum, were grown under contrasting daylengths [18 : 6 h light : dark cycles (LD) versus 6 : 18 h LD] and phosphorus (P) regimes (P-sufficient versus 1 lM P). The rates of growth and photosynthesis, as well as growth efficiencies and pigment concentr...

The aim of this study was to clarify the relation among systolic blood pressure (SBP), serum insulin, leptin, visceral fat accumulation and family history of hypertension, and to elucidate the pathophysiologic mechanism of blood pressure elevation in obese children. This study examined 109 obese children with a family history of hypertension (OF: 77 boys and 32 girls), and 83 obese children wit...

To reduce emissions and save energy, alternative fuel dual-fuel mode have been widely applied in the field of diesel engines. The pilot injection has potential to engine vibration noise pollutant emissions. effects a strategy on performance an ethanol/F-T were experimentally investigated four-cylinder four-stroke common rail modified with ethanol system. results indicate that variation combusti...

Aspergillus niger reproduces asexually by forming conidia. Here, the minimal nutrient requirements were studied that activate germination of A. To this end, was monitored in time using an oCelloScope imager. Data used as input asymmetric model to describe process swelling and germ tube formation. The maximum number spores (Pmax) activated swell form tubes 32.54% 20.51%, respectively, medium wit...
