Tailings pond sediment-exposed walleye exhibited a delay in development, as well as increased percentages of larvae with heart and yolk sac edema, and cranial and spinal malformations.
The congee of mud crab, palm heart, egg yolk emulsion is salty with a sea-like taste broken up by the sweet chunks of crab, while in the next course of XO Sea, the very salty Chinese-influenced XO stock is brought to the table in an iron tea pot and poured over seafood of – once again – competing textures.
The main malformation of VPN was growth retardation, and TPM-induced multimalformation included heart edema, yolk deformity, and scoliosis.
For example, genetic ablation of the murine gene encoding TGFβR2 (Tgfbr2) using Tie1-Cre leads to lethality by E10.5 resulting from heart and yolk sac vascular defects (Carvalho et al., 2007).
Of note, for reasons of comparability, we focused on observations in the skin of the heart and yolk sac area; we could, however, also observe soft tissue calcification, which was associated with cathepsinK-positive cells, in other loci, such as the brain and the heart itself (not shown).
To verify our method in practice, we acquired image sequences of a live rat embryo (11.5 days post coitus) using a swept-source OCT (SS-OCT) system as described previously in [ 3]. Figure 2 shows a representative frame of an SS-OCT image series of the embryonic heart and yolk sac acquired at different frame rates and spatial resolutions.

FACS analyses of E9.5 Nkx2 5IRES-Cre/+; R26YFPR/+ embryos suggested that about 16%and7.5%5% of CD41+/c-kit+ cells in the heart and the yolk sac, respectively, were derived from Nkx2 5+ cells (Supplementary Fig. S8).
In studies following the Exxon Valdez disaster, and in laboratory studies, scientists have found that fish embryos exposed to oil develop abnormalities of their jaws and body axis, and swelling (edema) involving their heart and their yolk sacs.
Expression of Sdf-1γ increased from E15.5, becoming the most abundant Sdf-1 transcript at E18.5 in the developing heart, AGM and yolk sac.
