1. Analysis of the dynamic of origin and fate of trophoblast cells in the maternal-fetal interface of pregnant guinea pig uterus to elucidate inverted yolk sac organization / Análise da dinâmica da origem e destino das células trofoblásticas na interface materno-fetal do útero gestante do cobaio na elucidação da organização da placenta vitelina invertida
A implantação embrionária e a placentação em cobaios são caracterizadas pela presença trofoblastos que se destacam da placenta principal, semelhantes ao trofoblasto extra-viloso de humanos. Nestes animais ultrapassam os limites, e podem ser encontrados infiltrados no profundamente no endométrio e no em ambiente externo ultrapassando aos limites da pa

2. Differential expression of cell surface sialoglycoconjugates on wild-type and cultured Ehrlich tumor cells as revealed by quantitative lectin-gold ultrastructural cytochemistry.
Three variants of the classical Ehrlich ascites tumor (EAT) cell have been studied by quantitative, sialic acid-specific, lectin-gold ultrastructural cytochemistry. Electron microscopic examination revealed pronounced differences in the surface morphology of the three cell variants. The wild-type Ehrlich cells (EAT-wt), grown in the peritoneal cavity of mice

3. Increased lectin binding capacity of trophoblastic cells of late day 5 rat blastocysts.
The binding of lectins to the trophoblast of rat blastocysts has been studied using quantitative ultrastructural cytochemistry. Rat blastocysts from early, mid and late d 5 of gestation were stained using biotinylated lectins (Phytolacca americana [Phy am], fucose binding protein [FBP] and soybean agglutinin [SBA]) and a sensitive avidin-ferritin cytochemica

4. Identification of chitin as a structural component of Giardia cysts.
The intestinal parasite Giardia lamblia is a significant cause of diarrheal disease, which is perpetuated by the infective cyst form of the parasite. Although a rational approach to the control of giardiasis would be to inhibit cyst formation, nothing is known of the chemical composition of the cyst wall or of its biosynthesis. In these studies, we have show

5. Galectin-4 and Small Intestinal Brush Border Enzymes Form Clusters
Detergent-insoluble complexes prepared from pig small intestine are highly enriched in several transmembrane brush border enzymes including aminopeptidase N and sucrase-isomaltase, indicating that they reside in a glycolipid-rich environment in vivo. In the present work galectin-4, an animal lectin lacking a N-terminal signal peptide for membrane translocati

6. DS28-6, a temperature-sensitive mutant of Chinese hamster ovary cells, expresses key phenotypic changes associated with brefeldin A treatment.
The temperature-sensitive Chinese hamster ovary (CHO) cell mutant DS28-6 has been previously shown to be pleiotropically defective in protein secretion. We have examined the mutant cells to determine the intracellular site of the block in secretion. By transmission electron microscopy a time-dependent disassembly of the Golgi apparatus was found under nonper
