We discuss the design of reaction-diffusion systems that display a variety of spatiotemporal patterns. We also consider how these patterns may be controlled by external perturbation, typically using photochemistry or temperature. Systems treated include the Belousov-Zhabotinsky (BZ) reaction, the chlorite-iodide-malonic acid and chlorine dioxide-malonic acid-iodine reactions, and the BZ-AOT sys...

objective(s):the limited homing potential of bone-marrow-derived mesenchymal stem cells (bm-msc) is the key obstacle in msc-based therapy. it is believed that chemokines and chemokine receptor interactions play key roles in cellular processes associated with migration. meanwhile, mscs express a low level of distinct chemokine receptors and they even lose these receptors on their surface after a...

Background: β-thalassemia is an autosomal hemoglobinopathy with inconsistent universal distribution. Among patients with thalassemia diverse non-siderotic complications distinctly influence the attribute of life, including zinc deficiency due to varied etiologies. The objective of the present study was to determine zinc levels in patients with β-thalassemia major and its correlation with mat...

Disturbance of iron metabolism is a prominent feature of the anaemia of rheumatoid arthritis. The plasma iron concentration is almost always reduced in the presence of active disease (Bruzzone and Massimello, 1940; Nilsson, 1948). Despite intensive investigation (Raymond, Bowie, and Dugan, 1965), the metabolic pathways of iron in rheumatoid disease and the relationship between the levels of pla...

A method is described for the estimation of ferrioxamine and of desferrioxamine when either or both are present in urine.
