BACKGROUND The aim of this study was to determine the relationship between body position, pulmonary function (PF) and bronchial blood flow (Q(aw)) in a group of heart failure (HF) and control subjects. METHODS Thirty-six subjects were studied: 24 stable, ambulatory HF patients (HF: LVEF=27±6%, age=65±9 yr) and 12 age- and sex-matched controls (CTRL: LVEF=60±7%, age=62±8 yr). Measures of Q˙(aw...

OBJECTIVES We administered aerosolized histamine to 32 subjects with tetraplegia to determine whether there were differences in spirometric and/or lung volume parameters between responders and nonresponders. RESULTS Baseline pulmonary function parameters revealed mild to moderate restrictive dysfunction. We found that 25 subjects (78%) were hyperreactive to histamine (mean provocative concent...

The toxicity of mixtures of copper, zinc, and diazinon were determined for Ceriodaphnia dubia using 7-d survival and reproduction tests. Fifteen treatments, including combinations of the chemicals at 0, 25, 50, 75, and 100% of their individual median lethal concentrations, adding up to one toxic unit (TU) were tested. The TU was then used to classify each mixture response as additive, greater t...

The association of high vitamin A intake and low bone mineral density (BMD) is still controversial. To determine the association of dietary vitamin A intake and serum 25-hydroxyvitamin D (25(OH)D) concentration with BMD, a total of 6481 subjects (2907 men and 3574 women) aged ≥50 years from the Korean National Health and Nutrition Examination Survey (2008-2011) were divided into groups accordin...

Povzetek. Sodobne organizacije se spreminjajo zelo pogosto. Spremembe se poskuša izvesti hitro in učinkovito. Spremembe pogosto vključujejo spremembe IS zaradi njegovega pomena v organizacijah. Odpor do sprememb spada med ključne dejavnike uspeha večjih projektov in programov IT. Obvladovanje odpora ne pomaga organizacijam zgolj izvesti spremembe hitreje in učinkoviteje, temveč je hkrati tudi p...

(b) We do several iterations of eliminating strictly dominated strategies. First, note that when v < 75, bidding 75 is strictly dominated: regardless of the other bidder’s strategy, you will win the auction at least half the time, giving strictly negative payoff, while bidding 0 ensures a payoff of 0. Second, assume your opponent never bids 75 unless his value is at least 75. Then a bid of 50 w...

BACKGROUND Adolescence is a period of change, which coincides with disease remission in a significant proportion of subjects with childhood asthma. There is incomplete understanding of the changing characteristics underlying different adolescent asthma transitions. We undertook pathophysiological characterization of transitional adolescent asthma phenotypes in a longitudinal birth cohort. MET...

To study seasonal inter-individual and intra-individual variations in serum 25-hydroxy vitamin D (25(OH)D) and to explore parameters associated with 25(OH)D in a healthy Swedish adult population. 540 blood donors (60 % men; mean age 41 ± 13 years) and 75 thrombocyte donors (92 % men, aged 46 ± 11 years) were included. Serum was collected during 12 months and analyzed for 25(OH)D and parathyroid...

Vital kapasitenin %25-%75 arasındaki zorlu ekspiratuar akım (FEF%25-75) küçük hava yolu hastalığı (KHH)’nın değerlendirilmesinde kullanılan solunum fonksiyon testi (SFT) parametresidir. Çalışmamızda, göğüs hastalıkları polikliniğine başvuru yapan FEF%25-75 düşüklüğü saptanan hastaların polikliniğe nedenleri, FEF%25-75’in kronik obstrüktif akciğer (KOAH)’ın erken teşhisine katkısı ve risk faktör...
