Primary serous papillary adenocarcinoma of the fallopian tube.

Fallopian tube cancer is least common of all gynecologic tumors, with the mean age at onset between 54 and 63 years. This case report presents a 67-year-old female, gravida 1, para 1, with primary adenocarcinoma of the fallopian tube, detected and diagnosed preoperatively in clinical stage IIIc. The patient was asymptomatic, with only mild vaginal discharge of amber color and normal measured value of CA 125.

Two-dimensional electrophoresis of plasma membranes, showing differences among wild-type and abnormal ascospore mutant strains of Neurospora crassa.

Plasma membranes isolated from vegetative cultures of wild-type Neurospora crassa were analyzed by two-dimensional electrophoresis, followed by staining with silver nitrate to visualize proteins and fluorescein-labeled concanavalin A to visualize glycosylated subunits. Mycelial plasma membranes from strains carrying mutations affecting ascospores were also analyzed. Two of the mutant strains were shown to have aberrant two-dimensional membrane subunit patterns.

Molecular alteration in a Neurospora crassa morphological mutant and its phenocopy.

A procedure using ion exchange chromatography has been developed to detect alterations in a polysaccharide produced by Neurospora crassa. The polysaccharide, isolated from medium that has supported the growth of a culture, is highly responsive to the 3-methyl-2-benzothiazolinone hydrazone assay, indicating a high hexosamine content. The substance elaborated by wild-type N.

Occurrence of a major protein associated with fruiting body development in Neurospora and related Ascomycetes.

Electrophoretic and immunological analysis of fruiting body (perithecial) extracts demonstrates the occurrence of a major phase-specific perithecial protein in all Neurospora species and in the closely related Gelasinospora cerealis and Sordariafimicola. The perithecial proteins from these different species fall into a number of groups with different electrophoretic mobilities. They appear to be immunologically closely related but not identical to one another even within the same genus, with only partial identity exhibited between the heterothallic and pseudohomothallic Neurospora on the one hand and the homothallic Neurospora on the other hand.

Genetically related protein variants specifically associated with fruiting body maturation in Neurospora.

Electrophoretic analysis of fruiting body extracts from Neurospora reveals a characteristic protein, apparently absent in vegetative structures and ascospores, and which increases markedly in relative concentration after fertilization. Different wild-type species and strains studied have electrophoretic variants of this protein, two of which are shown to be controlled by members of an allelie pair.

Evidence for the differentiation of wild-type alleles in different species of neurospora.

Wild-type alleles at the peak locus of Neurospora have been transferred by backcrossing from N. sitophila and N. tetrasperma to N.

Dominance modifiers in neurospora crassa: phenocopy selection and influence of certain ascus mutants.

When homozygous in zygotes, mutant alleles at the peak locus in linkage group V of Neurospora crassa initiate aberrant asci that are nonlinear, in contrast to the linear asci characteristic of wild type. Most mutant alleles are recessive, inasmuch as crosses of the mutant strains with wild type give linear asci. However, five different mutant alleles, when heterozygous with the wild-type allele, act in varying degrees as zygote dominants, initiating both linear and nonlinear asci, the relative proportions depending on the allele.
