    Notes: Abstract Patients with glycogen storage disease type Ib (GSD Ib) suffer from recurrent bacterial infections due to neutropenia and neutrophil dysfunction. To improve the quality of life in a 9-year-old boy with GSD Ib, we subeutaneously administered recombinant human granulocyte colony-stimulating factor (G-CSF). Daily injections of 100 μg/m2 of G-CSF significantly increased absolute neutrophil counts and augmented neutrophil mobility. The patient was then treated with 70 and 100 μg/m2 of G-CSF daily and twice-weekly. The treatment maintained absolute neutrophil counts at significantly higher levels than those without treatment for 22 months and markedly decreased the frequency of infections and the necessity for hospitalisation. No adverse effects were observed during treatment. These findings indicate that daily and twice-weekly treatment with G-CSF of long duration are safe and effective for patients with GSD Ib. G-CSF may be a useful therapeutic agent in patients with neutrophilic impairment as a consequence of a metabolic disorder.

    Notes: Abstract Recently, evolutionary robotics (ER) has been attracting a lot of attention in the field of robotics artificial life and so on. ER approaches are expected to provide feasible methods to design controllers for autonomous mobile robots with less human intervention. However, most of the conventional studies in ER have been aiming at obtaining very simple (trivial) behaviors such as obstacle avoiding, wall following, and target approaching. To make the ER approach more fruitful, we should pay close attention to obtaining nontrivial behaviors. Based on these considerations, in this paper we propose a method for obtaining nontrivial behaviors using a developmental process with a carefully arranged grafting method. To verify the validity, we apply our idea to the construction of neural controllers that can cope with rough terrain.
