Background Functional single ventricle (FSV) is a spectrum of severe congenital heart disease, with multiple anatomic variations but similar surgical treatment strategies. FSV patients are living longer into adulthood compared to two or three decades ago, and they are more frequently undergoing imaging to assist in clinical and surgical management....

Background With the advent of the term “Heart Failure with Preserved Ejection Fraction - HFpEF”, more and more evidence has emerged supporting the importance of Speckle Tracking Echocardiography in measurement of Left ventricular (LV) Strain to assess subtle myocardial systolic dysfunction in such patients. Aim: To assess Global Longitudinal stain...

—During a change in operating condition, oscillations of small magnitude and low frequency often persist for long periods of time and in some cases even present limitations on power transfer capability. Generators in power systems are equipped with automatic voltage regulator (AVR) to control terminal voltage. It is known that AVR has a detrimental...

Accurate fault locator (FL) algorithms become an essential requirement to increase system reliability in modern utility grids. Several FL algorithms based on phasor measurement units (PMUs) have been developed in the last two decades. Among the most common approaches, two distinctive FL concepts (Novosel and Jiang) are detailed in this paper. The s...

The behavior of dromedary milk during the ultrafiltration on mineral membrane was studied comparatively with that of cows' milk. At native pH, dromedary milk was marked by a better flux and a lower protein retention rate. Analysis of the corresponding permeates revealed that dromedary milk had lower mineral and citrate contents in the serum phase....

The ability of dromedary skim milk to form an acid curd during a lactic acid starter fermentation was investigated. The activity of the starter in dromedary milk was characterized by a longer lag phase ( approximately 5 vs. approximately 1 h) and by an earlier decline phase. This suggests the presence of inhibiting factors. The maximum buffering ca...

Direct addition of lactic acid was used to follow the behaviour of reconstituted skimmed milk during a chemical acidification. The mobility of the micellar materials: minerals and caseins, was correlated with the change in a range of physicochemical parameters such as buffering capacity and conductivity. It was hypothesized that, for a given pH, th...

An IgG2a anti-Schistosoma mansoni mouse monoclonal antibody was shown to passively protect Swiss mice. The 74 kDa target antigen was isolated from antigenic extracts of S. mansoni adult worms. Swiss and C57 BL/6J mice were immunized with 30, 50, 100 and 200 microg antigen/mouse doses with and without Freund's adjuvant. Sera of immunized mice showed...

Monoclonal antibodies can confer resistance to schistosome infections. This has led to identification of several protective antigens. An IgG2a monoclonal antibody designated BRL4 mAb identified a 74-kDa antigen in antigenic extract of Schistosoma mansoni adult worms. The target antigen was localized in gut and tegument. In 3 passive transfer experi...

A polypeptide antigen of 74.0 kDa molecular weight was detected in the antigenic extracts of the 3 developmental stages of Schistosoma mansoni (eggs, cercariae, and adult worms) by western blotting using BRL4 monoclonal antibody (mAb) that significantly protected mice at the levels of 51.6%, 42%, and 53.8% against challenge S. mansoni infection in...
