The eggs of Capissa vagesa (Moore, 1859) and Trabala vishnou (Lefèbvre, 1827) from the families Erebidae Lasiocampidae were examined characterized under scanning electron microscope. Significant morphological traits on eggshells both analyzed species are presented in current study. Descriptions comparative assessments for these moths provided, addition to structural complexity uncovered through...

Results This lady was referred to our perinatology unit at 33 week's gestation for vaginal bleeding and abdominal pain. There were slight vaginal bleeding and minimal uterine contractions. Ultrasonographic examination revealed a single live fetus compatible with gestational age and circumvallate placenta (Fig 1). She received two doses of dexamethasone for accelerating fetal lung maturation. Tw...

Growth was measured in dechorionated and chorionated embryos of rainbow trout Oncorhynchus mykiss exposed to three oxygen treatments: hypoxia, normoxia and hyperoxia (nominally 5, 10 and 15 mg l ). Dechorionated embryos grew faster than chorionated ones in all three oxygen treatments. Similar patterns, however, were found in both dechorionated and chorionated groups; embryos exposed to hypoxia ...

We described the organization of two silkmoth chorion genes, called E1 and E2, whose expression is largely restricted in time to the very late period of choriogenesis and in space to one of two major subpopulations of follicle cells. Using E1 and E2 clone cDNAs as probes, we showed that gene copy numbers per haploid genome remain constant throughout silkmoth development despite major changes in...

Pattern formation during epithelial development requires the coordination of multiple signaling pathways. Here, we investigate the functions of an ovary-enriched miRNA, miR-318, in epithelial development during Drosophila oogenesis. mir-318 maternal loss-of-function mutants were female-sterile and laid eggs with abnormal morphology. Removal of mir-318 disrupted the dorsal-anterior follicle cell...

The chorio-allantoic placenta forms through the fusion of the allantois (progenitor tissue of the umbilical cord), with the chorionic plate. The murine placenta contains high levels of hematopoietic stem cells, and is therefore a stem cell niche. However, it is not known whether the placenta is a site of hematopoietic cell emergence, or whether hematopoietic cells originate from other sites in ...
