A growing body of evidence suggests that the consumption of foods rich in polyphenolic compounds, particularly cocoa, may have cardioprotective effects. No review, however, has yet examined the effect of flavonoid-rich cocoa (FRC) on all major cardiovascular risk factors or has examined potential dose-response relationships for these effects. A systematic review and meta-analysis of randomized,...

DNA vaccination offers a strategy to induce immune attack on cancer cells, but tumor Ags are often weak. Inclusion of a "foreign" protein increases immunogenicity, and we found previously that fusion of the fragment C (FrC) of tetanus toxin to the tumor Ag sequence promotes Ab and CD4(+) responses against B cell tumors. For CTL responses, use of the full two-domain FrC may be less helpful, beca...

OBJECTIVE To investigate the effects of positive end-expiratory pressure (PEEP) on end-expiratory lung volume (EELV) and mean oscillated flow rate (VOSC) during high-frequency chest compression (HFCC) in normal subjects and patients with severe COPD. DESIGN Comparative study. SETTING Pulmonary function and lung mechanics laboratory, University of Alberta Hospitals. PARTICIPANTS Six normal...

BACKGROUND In ventilated newborns the use of multiple breath washout (MBW) techniques for measuring both lung volume and ventilation inhomogeneity (VI) is hampered by the comparatively high dead space fraction. We studied how changes in ventilator settings affected VI indices in this particular population. METHODS Using a computer simulation of a uniformly ventilated volume the interaction be...

Problems with appraisal-based return series combined with certain similarities between commercial real estate, bonds and stock suggest that equity REIT returns provide an accurate source of real estate pricing information. A model for deriving a discount rate for unsecuritized commercial real estate was developed. The model is a three factor Arbitrage Pricing model that measures the sensitivity...

Megakaryopoiesis is the hierarchical differentiation of hematopoietic stem cells into megakaryocytes. Differentiating megakaryocytes undergo maturation characterized by endomitosis and produce numerous platelets through proplatelet formation. C-type lectin-like receptor 2 (CLEC-2) is a podoplanin (PDPN) receptor mainly expressed on platelets and megakaryocytes. Deletion of platelet/megakaryocyt...

Objective: To evaluate the utility of inspiratory capacity (IC) measured by simple spirometry as an indirect measure of air trapping. Method: Functional residual capacity (FRC) and IC were determined, respectively, by a body plethysmography and by spirometry. Air trapping was defi ned by a FRC higher than 120%. Spearman’s rho between IC and FRC is determined and the receiver operating character...

Data on the shape of the chest wall at total lung capacity (TLC) and functional residual capacity (FRC) were used as boundary conditions in an analysis of the deformation of the dog lung. The lung was modeled as an elastic body, and the deformation of the lung from TLC to FRC caused by the change in chest wall shape and gravity were calculated. Parenchymal distortions, distributions of regional...

We have studied the effects of extrinsically applied PEEP (PEEPe) and intrinsic PEEP (PEEPi) on lung volume and peak airway pressure (Paw,peak) in 10 patients with airflow limitation during mechanical ventilation. PEEPe was applied in 2-4 cm H2O increments until values greater than PEEPi were reached. Total lung hyperinflation was quantified by measuring the expired volume resulting from deflat...

The fragmented red cell (FRC) is a useful index for diagnosing and determining the severity of thrombotic thrombocytopenic purpura (TTP), thrombotic microangiopathy (TMA) and other similar conditions, as it is found in peripheral blood in patients with these diseases. The FRC expression rate has conventionally been determined by manual methods using smear samples. However, it is difficult to at...
