Prolonged increases in fetal lung expansion stimulate fetal lung growth and development, but the effects on pulmonary hemodynamics are unknown. Our aim was to determine the effect of increased fetal lung expansion, induced by tracheal obstruction (TO), on pulmonary blood flow (PBF) and vascular resistance (PVR). Chronically catheterized fetal sheep (n = 6) underwent TO from 120 to 127 days of g...

BACKGROUND Partial rebreathing is a noninvasive method for measuring pulmonary blood flow (PBF). This study examines the systematic errors produced by the partial rebreathing technique utilizing a comprehensive mathematical model of the cardiorespiratory system of a healthy, 70-kg adult male. METHODS The model simulates tidal breathing through a branched respiratory tree and incorporates the ...

Pattern information and natural language information used together can complement and reinforce each other to enable more effective communication than can either medium alone (Feiner 91) (Nakamura 93). One of the good examples is a pictorial book of flora (PBF). In the PBF, readable explanations which combine texts, pictures, and diagrams are achieved, as shown in Figure 1 and 2. Taking advanta...

BACKGROUND AND AIMS Pulmonary hypertension (PH) is increasingly recognised in patients with diffuse lung disease, and is associated with increased mortality. Cardiac output (CO) is a prognostic marker in PH. Non-invasive assessment of pulmonary blood flow (PBF(INNOCOR)) with the inert gas rebreathing Innocor device has been validated against CO in PH, but not in PH associated with parenchymal l...

The purpose of this study was to investigate the effect of tooth supported (TSD) and tooth-tissue supported (TTSD) removable partial denture wearing on pulpal blood flow (PBF) of the abutment teeth by using Laser Doppler Flowmeter (LDF). Measurements were carried out on 60 teeth of 28 patients (28 teeth and 12 patients of TTSD group, 32 teeth and 16 patients of TSD group) who had not worn any t...

Nitric oxide (NO) is a vasodilator substance controlling renal papillary blood flow (PBF) in the rat. In this study we have evaluated the role of AT1 angiotensin II receptors as modulators of the whole kidney and papillary vasoconstrictor effects induced by the acute or chronic inhibition of NO synthesis. Experiments have been performed in anesthetized, euvolemic Munich-Wistar rats prepared for...

OBJECTIVE The present study tested the extent to which age and obesity predicted impulsive choices for food and monetary outcomes and tested how a brief mindful-eating training would alter delay discounting for food and money choices compared with control groups. METHOD First, 172 adolescents (Mage = 13.13 years) and 176 (Mage = 23.33 years) adults completed the Food Choice Questionnaire (FCQ...

Effective closure of the postpneumonectomy bronchopleural fistula (PBF) with the use of different techniques still remains a challenge for thoracic surgeons. The aim of this study was to evaluate the efficacy of modified method of PBF closure using pedicled pericardial flap (PPF) supported by fibrin glue (FG). The efficacy of the late PBF closure with the use of two surgical methods was compare...

Understanding the impact of obesity on elective total joint arthroplasty (TJA) remains critical. Perioperative outcomes were reviewed in 316 patients undergoing primary TJA. Higher percent body fat (PBF) was associated with postoperative blood transfusion, increased hospital length of stay (LOS) >3 days, and discharge to an extended care facility while no significant differences existed for BMI...

The general form of PBFs corresponding to one weight WM filters, which are a subclass of WM filters, is derived in this paper. Based on the results, it is straightforward to derive the corresponding PBF from a given one weight WM filter or vice versa. The results can also be used to check whether an PBF corresponds to an one weight WM filters. The checking procedure is very simple and tractable...
