The ectoproct coelom is formed by neither of the processes used by other bilaterians, enterocoely, in which pouches that form on the wall of the gut become separate cavities, nor schizocoely, in which the tissue between the gut and the body wall splits, forming paired cavities.
One was a system in which a pouch of urine -- usually from a teammate who did not use a performance-enhancing drug -- was taped to the upper back of the player under his shirt.
The electrodes were immersed in nonaqueous electrolyte (1 M LiPF6 in ethyl carbonate/dimethyl carbonate 1 1) for 12 h, after which the pouch cell was hermetically sealed in laminated aluminum case and tested.
In particular, we observed reduced expression of the ectomesenchyme marker dlx2a in the posterior arches of tbx1 mutants, even at stages before those at which the pouches normally form.
Although this is a highly gregarious and colonial species, most of the focal animals refused to roost in a pouch which contained non-roostmate odors when given a choice including a control pouch and one containing a roostmate odor.
In contrast to stably transgenic nkx2.5 Wnt11r embryos, which never displayed pouch or cartilage defects on their own, a few nkx2.5 Fgf8a-GFP embryos did display subtle pouch ankx2.5 Fgf8a-GFPal cartilagembryosts, consistent with the local guididce function of Fgf8a that is displayed below (subtlementary material Fig. S3O-T).
The most prominent feature of phoronid metamorphosis is the eversion of the metasomal sac, which is a ventral pouch of the body.
When sample 21 pouches were cut open, it was noticed that there was a thin film in each pouch, which might have caused the slower release of nicotine from the sample.
You could imagine all of the above sporting this strappy acid-yellow pouch, which Ms. Gryson has nicknamed the "bar bag".
Attendants come up to the end of each pew with a velvet pouch, which is passed down the line.
