    Notes: Abstract Neurological development in preterm children with birth weight appropriate for gestational age is reported in two separate groups: a longitudinal study of 97 preterm children and 93 term children as a control group and a cross-sectional study of 249 preterm children. Both preterm groups were regarded as high risk with respect to number of outborns, distribution of gestational age and perinatal risk factors. Neurological outcome at 5–6 years of age in the majority of the preterm children was comparable to that of the term children. However, 15% of boys and 9% of girls in the preterm group were diagnosed as having cerebral palsy. Mild diplegia was most frequently observed; 4% of the children were severely impaired. Fourteen percent of the preterm vs 2% of the term boys and 6–9% of the preterm vs none of the term girls received motor therapy during early school age. There was a small but consistent sex difference in neurological outcome in favour of the term and preterm girls. Effects of drop out rate and of incompleteness of ascertainment are reported in detail.

    Notes: Abstract  The objectives of this study were to estimate the outcrossing rate and to explain genetic consequences of the development of seed in the endocarp in a natural population of neem in Bangladesh. Cotyledons of germinated open-pollinated seeds of individual trees were analyzed by starch-gel electrophoresis to examine allozymes. Three loci with clear Mendelian segregation were used to estimate outcrossing rate. A multilocus mixed mating model was used to evaluate the mating system. The population exhibited high outcrossing rates both for multilocus (tm=0.90±0.024) and mean single-locus (ts=0.92±0.020) estimates. The difference between these two parameters (tm–ts=0±SE 0.038) was insignificant, indicating that there was no ’biparental inbreeding’ in the population. The degree of variance of the estimates of multilocus outcrossing rates decreased when two or more loci were included. In order to elucidate the significance of polycarpy a total of 471 seeds were counted out of 440 endocarps. This mechanism appears to be a possible way of avoiding inbreeding. The results indicated that the studied neem population was predominantly allogamous.
