The effect of human activated protein C (APC) on fibrinolysis was studied in a cell-free system by continuously monitoring the thrombin-induced formation and subsequent tissue-type plasminogen activator-induced degradation of fibrin. In systems comprising dialyzed human plasma, APC shortens the time for lysis to occur in a concentration-dependent, saturable manner. Half-maximal activity occurs ...

Our current understanding of the origin of barium and S stars is briefly reviewed, based on new orbital elements and binary frequencies. 1. The relation of barium and S stars to carbon stars Since the last conference (IAU Coll. 106, Evolution of Peculiar Red Giants, Johnson & Zuckermann eds., 1989) devoted to chemically-peculiar red giants (PRGs), much progress has been made in understanding ho...

Barium radiology remains the method of choice for the diagnosis and evaluation of many small intestinal disorders. Enteroclysis (small bowel enema) is proving to be a quick and efficient way of examining the small intestine. During enteroclysis the intestine is distended with barium contrast medium, clearly demonstrating any morphological changes that may be present.

osseointegration has been the concern of implantology for many years. researchers have used various ceramic coatings for this purpose; however, piezoelectric ceramics (e.g., barium titanate [bto]) are a novel fi eld of interest. in this regard, bto (batio3 , bto) coating was fabricated by electrophoretic deposition on ti6al4v medical alloy, using sol-gel-synthesized nanometer bto powder. struct...

This paper addresses the question of why metal-deficient barium stars are not yellow symbiotic stars (YSyS). Samples of (suspected) metal-deficient barium (mdBa) stars and YSyS have been collected from the literature, and their properties reviewed. It appears in particular that the barium nature of the suspected mdBa stars needs to be ascertained by detailed abundance analyses. Abundances are t...

' 2004 Canadian Medical Association D of the appendix is an uncommon cause of rightlower-quadrant pain. Whether it presents symptomatically or is an incidental finding at surgery or barium enema, understanding its clinical behaviour is important for its management. We report here a case of appendiceal diverticulitis including what we believe to be the first reported case of this condition diagn...

synthesis of bafe12o19 magnetic nano particles via precipitation in different ph conditions have been reported. the certain molar ratio of fe/ba = 12 selected and sodium hydroxide was used as a precipitant agent. x-ray diffraction (xrd), scanning electron microscopy (sem) and vibrating sample magnetometer (vsm) were used to consider the structural, morphological and magnetic properties of bariu...
