Predators typically avoid tricolour ringed patterns (Brodie 1993; Brodie & Janzen 1995; Hinman et al. 1997; Pfennig et al. 2001; Harper & Pfennig 2007; Pfennig et al. 2007; Harper & Pfennig 2008; Kikuchi & Pfenn...

by a ringed prosthetic graft in the left side by which the patient is haemodialysed over two months now. The unusual and frequent thrombosis of central veins in our patient may be due to recurrent cannulation, to some infections and to short bowel syndrome which may cause apolipoprotein abnormalities. We decided that the last placed prosthetic graft between subclavian artery and jugular vein sh...

A 5 1/2-yr-old child developed severe anemia with erythroid hypoplasia and 50% ringed sideroblasts in his bone marrow. A serum inhibitor of erythropoiesis was demonstrated, utilizing syngeneic and autologous bone marrow in a plasma-clot culture system. The IgG fraction of the patient's serum effected similar suppression of erythroid colony formation. Prednisone therapy was ineffective, but foll...
