[Opinion of women from a family health unit about the quantity of mothermilk produced].

This is a study aimed at knowing the opinion of women about the quantity of mothermilk produced, since insufficient milk is one of the main reasons mentioned by women from different cultures when introducing complementary feeding in children's diet before the fourth month of life. The interviews were made at the homes of 41 women from a family health unit in the Eastern area of S o Paulo City in 1998 and 1999. The majority of the mothers (82.

Goosecoid and cerberus-like do not interact during mouse embryogenesis.

Mouse Cerberus-like (Cer-l) is a neural inducer molecule, capable of inhibiting Nodal and BMP-4 signals in the extracelular space. The cer-l expression domain in the Anterior Visceral Endoderm (AVE) and prechordal plate, tissues involved in head induction and patterning, respectively, suggested a role for this gene in head formation. However, animals homozygous for the cer-l null allele failed to show any abnormality, leading us to propose the existence of other factor(s) that might compensate for cer-l loss-of-function.
