    Notes: ABSTRACT We report on 32 cases of Candida funisitis and describe the associated clinicopathologic features. The Candida funisitis was characterized grossly by small, circumscribed, yellow-white nodules on the umbilical cord surface and, microscopically, by subamnionic microabscesses in which fungal organisms were demonstrable. Chorioamnionitis was present in all cases. Twenty-four (75%) of the 32 infants were premature. There were 7 perinatal deaths, all in immature fetuses. Five (16%) of the 32 fetuses had congenital candidiasis. Five (16%) of the mothers had a history of intrauterine foreign body, including intrauterine contraceptive device in three and cervical cerclage in two. The diagnosis of Candida funisitis should prompt a careful examination for fetal infection, even though it is associated with congenital candidiasis in only a minority of the cases.

    Notes: In this study we concentrate on replacing side chains as a subtask of model building by homology. Two problems arise. How to determine potential low energy rotamers? And how to avoid the combinatorial explosion that results from the combination of many residues for which multiple good rotamers are predicted? We attempt to solve these problems by choosing position-specific rather than generalized rotamers and by sorting the residues that have to be modelled as a function of their freedom in rotamer space. The practical advantages of our method are the quality of the models for cases of high backbone similarity, the small amount of human intervention needed, and the fact that the method automatically estimates the reliability with which each residue has been modeled. Other methods described in this issue are probably more suitable if large backbone rearrangements or loop insertions and deletions need to be modeled. © 1995 Wiley-Liss, Inc.

    Notes: We have determined the nucleotide sequence of a cosmid (pIX338) containing the centromere region of yeast (Saccharomyces cerevisiae) chromosome IX. The complete nucleotide sequence of 33·8 kb was obtained by using an efficient directed sequencing strategy in combination with automated DNA sequencing on the A.L.F. DNA sequencer. Sequence analysis revealed the presence of 17 open reading frames (ORFs), four of them previously known yeast genes (sly12, pan1, sts1 and prl1), a tRNA gene and the centromere motif. Exhaustive database searches detected sequence homologues of known function for as many as 14 of the 17 ORFs. These include a mammalian tyrosine kinase substrate; the Escherichia coli cell cycle protein MinD; the human inositol polyphosphate-5-phosphatase (gene OCRL) involved in Lowe's syndrome, a developmental disorder; and helicases, for which the new yeast member defines a distinct DEAD/H-box subfamily. A surprisingly large fraction of the ORFs (at least six out of 17) in the centromeric region are apparently involved in RNA or DNA binding.The nucleotide sequence reported here has been submitted to the EMBL data library under the accession number X79743.
